AbstractWe report the discovery of the longest known radio pulsar period. PSR J2144–3933, previously thought to have a period of 2.84 s, actually has a period of 8.51 s. Under the usual assumptions about the stellar equation of state, this pulsar has an average surface dipolar magnetic field strength of ~ 2.0 × 1012G. According to popular theories of the emission mechanism this pulsar should not be emitting radio waves because its long period and magnetic field strength make pair creation impossible for all reasonable magnetic field configurations. Either assumptions about the equation of state are incorrect, or the emission theories must be revised.

Full textAbstract:
A 3-year field experiment was conducted at the Punjab Agricultural University, Ludhiana, during the rainy sea- son of ( kharif) 2006 to 2008, to study response of soybean [ Glycine max (L.) Merrill] to different levels of sulphur and born. The experiment comprised of 13 treatments including all the combinations of 4 sulphur (S) levels (10, 20, 30 and 40 kg/ha) and 3 boron (B) levels (0.5, 1.0 and 1.5 kg/ha) and absolute control (no S; no B). The highest grain yield, protein, oil content, gross and net returns of soybean were recorded with 40 kg S/ha, which were sta- tistically at par with 30 kg S/ha but significantly higher than other levels of sulphur. The productivity in 40 kg S/ha was enhanced 61.9% over the absolute control. The boron level of 1.5 kg/ha recorded the highest grain yield, gross and net returns, being statistically at par with 1.0 kg B/ha but significantly higher than 0.5 kg B/ha. The high- est S and B uptake were recorded in 40 kg S/ha and 1.5 kg B/ha respectively. The highest grain yield recorded in 40 kg S/ha and 1.5 kg B/ha was statistically at par with 40 kg S/ha and 1.0 kg B/ha, 30 kg S/ha and 1.0 kg B/ha, 20 kg S/ha and 1.5 kg B/ha and 30 kg S/ha and 1.5 kg B/ha treatments but was significantly higher than all the other combinations of sulphur and boron.

Full textAbstract:
A field experiment was conducted at New Delhi during 2003 and 2005 on sandy loam soil with 14.35 kg/ha available S to evaluate the relative efficiency of sulphur (S) sources and rates in pigeon pea [ Cajanus cajan (L.) Millsp.]wheat [ Triticum aestivum (L.) emend. Fiori & Paol.] cropping system. The study revealed that application of 30 kg S/ha being at par with 60 kg/ha produced 24.9 and 0.62 more pods/plant and seeds /pod respectively than control (no S). This increase in yield attributes finally led to 0.47 t/ha higher pigeon pea yield over no S ap- plication (1.15 t/ha). S applied to pigeon pea at 60 kg/ha left behind 1.19 kg/ha more S in soil than 30 kg/ha, which resulted in higher grain yield of succeeding wheat by 0.58 tonne/ha. Among the S sources, cosavet being on par with gypsum gave 14.8% (0.23 t/ha) more grain yield of pigeon pea over elemental S (1.55 t/ha). Both these sources also proved superior in their residual effect on succeeding wheat when compared with elemental S. Wheat responded to direct application of 30 kg S/ha only. Cosavet was the best source from productivity point of view. However, application of 30 kg S/ha to pigeon pea as gypsum and to wheat as elemental S was promis- ing in terms of S efficiency and economics.

Full textAbstract:
Low prices have prompted growers to contemplate transitioning to an organic system. We evaluated red clover-maize-soybean-wheat (Cl-M-S-W), maize-soybean (M-S-M-S), and soybean-wheat/red clover-maize-soybean (S-W/Cl-M-S) rotations in organic and conventional systems in New York, USA from 2015 to 2018 to identify profitable organic practices. Organic compared with conventional maize in 2017 had 14.6% higher yield and $2107/ha higher returns above selected costs in the S-W/Cl-M-S rotation; and had $1007/ha higher returns in the M-S-M-S rotation, despite 3.6% lower yield and higher production costs, because of the organic price premium. Likewise, organic compared with conventional soybean had ~$800 to ~$900/ha higher returns in 2017 and 2018, despite ~10% lower yield and ~$50/ha higher production costs, because of the organic price premium. Organic compared with conventional wheat yielded ~4% higher with $125/ha higher returns, despite ~$435/ha higher production costs. Organic compared with the conventional system had $1018/ha higher returns in the Cl-M-S-W rotation, $1782/ha higher in the M-S-M-S rotation, and $2961/ha higher in the S-W/Cl-M-S rotation in 2017 and 2018. Although returns in 2015 and 2016 (no organic premium) were lower, the organic compared with the conventional system from 2015 to 2018 had $673/ha higher returns in the Cl-M-S-W rotation, $497/ha higher in the M-S-M-S rotation, and $2355/ha higher in the S-W/Cl-M-S rotation indicating that the S-W/Cl-M-S rotation was the most profitable organic rotation during the four-year period.

Full textAbstract:
A novel biomedical material composed of spherical hydroxyapatite (s-HA) and polyamide 66 (PA) biocomposite (s-HA/PA) was prepared, and its composition, mechanical properties, and cytocompatibility were characterized and evaluated. The results showed that HA distributed uniformly in the s-HA/PA matrix. Strong molecule interactions and chemical bonds were presented between the s-HA and PA in the composites confirmed by IR and XRD. The composite had excellent compressive strength in the range between 95 and 132 MPa, close to that of natural bone.In vitroexperiments showed the s-HA/PA composite could improve cell growth, proliferation, and differentiation. Therefore, the developed s-HA/PA composites in this study might be used for tissue engineering and bone repair.

Full textAbstract:
AbstractField and greenhouse studies were conducted in 2016 and 2017 to determine sweetpotato tolerance to herbicides applied to plant propagation beds. Herbicide treatments included PRE application of flumioxazin (107 g ai ha−1), S-metolachlor (800 g ai ha−1), fomesafen (280 g ai ha−1), flumioxazin plus S-metolachlor (107 g ai ha−1 + 800 g ai ha−1), fomesafen plus S-metolachlor (280 g ai ha−1 + 800 g ai ha−1), fluridone (1,120 or 2,240 g ai ha−1), fluridone plus S-metolachlor (1,120 g ai ha−1 + 800 g ai ha−1), napropamide (1,120 g ai ha−1), clomazone (420 g ai ha−1), linuron (560 g ai ha−1), linuron plus S-metolachlor (560 g ai ha−1 + 800 g ai ha−1), bicyclopyrone (38 or 49.7 g ai ha−1), pyroxasulfone (149 g ai ha−1), pre-mix of flumioxazin plus pyroxasulfone (81.8 g ai ha−1 + 104.2 g ai ha−1), or metribuzin (294 g ai ha−1). Paraquat plus non-ionic surfactant (280 g ai ha−1 + 0.25% v/v) POST was also included. After plants in the propagation bed were cut and sweetpotato slip number, length, and weight had been determined, the slips were then transplanted to containers and placed either in the greenhouse or on an outdoor pad to determine any effects from the herbicide treatments on initial sweetpotato growth. Sweetpotato slip number, length, and/or weight were affected by flumioxazin with or without S-metolachlor, S-metolachlor with or without fomesafen, clomazone, and all fluridone treatments. In the greenhouse studies, initial root growth of plants after transplanting was inhibited by fluridone (1,120 g ai ha−1) and fluridone plus S-metolachlor. However, by 5 wk after transplanting few differences were observed between treatments. Fomesafen, linuron with or without S-metolachlor, bicyclopyrone (38 or 49.7 g ai ha−1), pyroxasulfone with or without flumioxazin, metribuzin, and paraquat did not cause injury to sweetpotato slips in any of the studies conducted.

Full textAbstract:
A field experiment was conducted during the kharif and rabi season of 2000-04 at Indian Institute of Pulses Re- search, Kanpur to find out the performance of maize ( Zea mays L.)-chickpea ( Cicer arietinum L.) cropping se- quence with sulphur fertilization along with farmyard manure (FYM). Inorganic S at 0 and 20 kg/ha was applied during kharif maize cultivation and in rabi season, three levels of S (0, 10 and 20 kg/ha) were applied with 2 levels of FYM (0 and 4 t/ha). Maize grain yield increased by 0.59 t with the application of 20 kg S/ha over control (1.99 t/ ha). Significant positive effects of 20 kg/ha of S as manifested on growth, yield attributes, yield, S uptake, S utiliza- tion and economics of maize were not further carried over to following chickpea crop. However, in chickpea nodu- lation, grain and straw yield, protein content, and S uptake significantly increased due to application of sulphur along with FYM application. Higher mean nodule number (19.38), nodule dry weight (0.213 g/plant), grain yield (1.69 t/ha), straw yield (1.78 t/ha), and S uptake (15.6 kg/ha) was found with the 20 kg/ha of S fertilization. But utili- zation of added S decreased with increased S supply. Net return and return per rupee investment of the system also increased due to application of S and FYM to chickpea.

Phosphorus (P) and Sulphur (S) are the most important plant nutrients which play significant roles in enhancing the early growth and development and increasing the fodder yield of maize. This important field study was planned to evaluate the P-S interaction effects on maize growth, fodder yield and nutrient (P and S) uptake. The soil used for study was clay loam, medium-alkaline (pH: 7.9), non-saline (EC: 0.85 dS m-1), strongly calcareous (CaCO3: 24 %), adequate in organic matter (1.6 %), low in ABDTPA-P (3.5 mg kg-1), while medium in SO4-S (21.5 mg kg-1). Eight P and S treatments were involved in this study, i.e. single application of each 90 kg P2O5 (T1) and 20 kg S ha-1 (T2); integration of 90 kg P2O5 with S @ 20, 40 and 60 kg ha-1 (T3, T4 and T5, respectively), and integration of 120 kg P2O5 with S @ 20, 40 and 60 kg ha-1 (T6, T7 and T8, respectively). The experiment followed an RCBD arrangement that was replicated thrice. Recommended seed rate of maize (95 kg ha-1) was used for sowing. The results revealed that shoot biomass production was maximum when maize plants received higher doses of P and S in an integrated manner (120-60 kg P2O5-S ha-1). At 30 DAS, shoot fresh biomass was found maximum, and statistically alike, when 90 or 120 kg P2O5 was integrated with S @ 60 kg ha-1. Shoot fresh biomass was maximum, at 40 DAS when 120-60 kg P2O5-S ha-1 was applied to maize. Shoot dry biomass after 30 days of sowing was highest when 90 kg P2O5 was applied with S @ 60 kg ha-1 or when, 120 kg P2O5 was used with S @ 40 and 60 kg ha-1. Shoot length was maximum, both at 30 and 40 DAS, in case of using 120-60 kg P2O5-S ha-1. Chlorophyll content of maize was maximum, both at 30 and 40 DAS, when 90 kg P2O5 was applied with S @ 60 kg ha-1. Maximum fodder yield of maize was noted when 120 kg P2O5 was applied with 60 kg S ha-1. Highest P-uptake, both at 30 and 40 DAS was noted when 120 kg P2O5 was applied with S @ 60 kg ha-1. At the first stage of growth, S-uptake was highest when 60 kg S was integrated with 90 kg P2O5 ha-1. The study advocated integrated application of 120-60 kg P2O5-S ha-1 for obtaining economically maximum fodder yield of maize.

There is large number of sulphur(S) sources available in the country and their efficiency need to be evaluated. In view of the meager information available on sulphur nutrition in a popular intercropping system of pigeonpea + groundnut. A field experiment was conducted during kharif 2003 and 2004 to evaluate the response of pigeonpea [ Cajanus cajan (L.) Millsp.] + groundnut ( Arachis hypogaea L.) intercropping system to FYM and S fertilization. Ap- plication of FYM at 5.0 t/ha significantly increased the yield and yield attributes, nutrient (NPK) uptake in pigeonpea and groundnut, system productivity (1.71 t/ha), net returns (Rs 18,287) and available S in soil after har- vest (15.72 kg/ha). However, B: C ratio was higher with crop receiving no FYM. Intercropping failed to influence the yield attributes, yield and nutrient uptake in pigeonpea, however, system productivity, net income and B: C ra- tio was higher in pigeonpea + groundnut system. The available soil S after harvest of crop(s) was lower in pigeonpea + groundnut system (13.11 kg/ha) when compared with sole pigeonpea (17.06 kg/ha). Application of sulphur at 35 and 70 kg/ ha, being on par, recorded significant increase in yield and nutrient uptake in pigeonpea and groundnut, system productivity and total net income over no S. The available soil S after harvest of crop (s) was higher with 70 kg S/ha. The S use efficiency indices were higher at lower i.e. 35 kg S/ha. Among the sources of sulphur, cosavet recorded higher yield and yield attributes, nutrient uptake and S use efficiency. However, the highest soil available S at harvest (19.34 kg/ha) was recorded with elemental S applied at 70 kg/ ha, while the highest net income (Rs 20,431) and B: C ratio (2.0) were achieved with gypsum at 35 kg S/ha.

The experiment was conducted at Agronomy field of Bangladesh Agricultural Research Institute, Gazipur during 2016-2017 and 2017-2018 to determine the nutrient requirement for yield maximization of Bt brinjal (var. BARI Bt Begun-2). The treatments were T1= STB (soil test base) recommendation (120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B+ 3 t/ha poultry manure), T2 = T1 + 25% of N-P-K-S-Zn-B (150-45-112-18-2.5-1.25 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure), T3= T1 + 50% of N-P-K-S-Zn-B (180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure), T4= T1 + 25% of N-P-K-S-Zn-B + 3 t/ha poultry manure (150-45-112-18-2.5-1.25 kg/ha N-P-K-S-Zn-B+6 t/ha poultry manure), T5= T1 + 3 t/ha poultry manure (120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B + 6 t/ha poultry manure). Nutrient uptake, yield components and yield of Bt brinjal varied significantly due to variation of nutrients in the tested years. The highest plant height (98-116 cm), canopy coverage (1.21-1.26 m2/plant), number of fruits/plant (57.69-59.23) and individual fruit weight (83-86 g) were obtained from 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure (T3) treatment where days to flowering showed the lowest values (109-110 days). The highest pooled yield (58.46 t/ha) of Bt brinjal was observed from the treatment 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B +3 t/ha poultry manure(T3) and the lowest (23.39 t/ha) from 120-36-90-15-2-1 kg/ha N-P-K-S-Zn-B+ 3 t/ha poultry manure) (T1). The highest nutrient uptake (214-43-208-60-0.38-0.213-49 kg/ha N-P-K-S-B-Ca) was also observed from the same treatment (T3). Fruit yield showed a strong (r=0.97) linear relationship with applied nutrients. Effect of nutrient application on fruit yield of Bt brinjal was estimated about 86%. The highest gross return (Tk. 587900/ha), gross margin (Tk. 417660/ha) and benefit cost ratio (3.45) were obtained by applying 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B+3 t/ha poultry manure. Results revealed that application of 180-54-135-22-3-1.50 kg/ha N-P-K-S-Zn-B along with 3 t/ha poultry manure would be economically optimum for achieving higher yield of Bt brinjal grown under Grey Terrace soil (Aeric Albaquept) of Gazipur.

Increasing levels of phosphorus up to 60 kg P2O5 ha-1 resulted in significantly higher grain (745 kg ha-1) and stover (1245 kg ha-1) yields and uptake of NPK and S by grain, stover and the whole plant over lower levels of phosphorus during both the years of the study as well as on pooled basis. But it was at par with 40 kg P2O5 ha-1 in respect to S uptake by grain during 2011, S uptake by stover during both the years and total S uptake during 2011. 45 kg S ha-1 produced significantly higher grain (743 kg ha-1) and stover (12264 kg ha-1) yields and uptake of NPK and S by grain, stover as well as total uptake over lower levels of sulphur during both the years of the investigation and on pooled basis. Interaction effect was significant in respect to total NPK and S uptake on pooled basis.

Tomato (Lycopersicon esculentum L.) was grown with polyethylene mulch and drip irrigation on a Millhopper fine sandy soil testing very high in P and low in organic matter during two season to evaluate the effect of S source, rate, and application methods on plant growth and yield of fruit. S rates of 34 and 68 kg S/ha were applied preplant (broadcast in the bed), by drip (10 weekly drip application), and by split applications (40% preplant and 60% drip). In split applications, S sources evaluated were ammonium sulfate and ammonium thiosulfate. Plant height was increased with S application from 0 to 68 kg S/ha in both studies. However, response on plant dry weight only occurred in Spring 1999. Total marketable yield was 17.9 tons/ha with 0 kg S/ha and was increased quadraticaly to 48.1 tons/ha with application of 68 kg S/ha in Spring 1999, but no response to S was obtained in the Spring 1998 study. Measured variable were not affected by S source and methods of application. Increasing S application from 0 to 68 kg S/ha reduced leaf and plant tissue P concentration 14% and 12% at mid season and 26% and 25% at late-season sampling, respectively. Application of 68 kg S/ha reduced soil pH ≈0.3 unit at the end of the season in both studies.

VBN-8) as a test crop.Factorial randomized block design with ten treatments (T1- Absolute control;T2-Recommended dose of NPK and S (Control);T3-Soil test based NPK; T4-T3 + S as Elemental Sulphur @ 40 kg S/ha; T5-T3 + S as BSGI@ 40 kg S/ha; T6-T3 + S as BSGII@ 40 kg S/ha;T7-T3 + Vermicompost @ 4 t ha-1; T8-T4 + Vermicompost @ 4 t ha-1;T9- T5 + Vermicompost @ 4 t ha-1; T10- T6+ Vermicompost @ 4 t ha-1 ) replicated thrice and 5 pots were maintained for each replication. The results of this study revealed that there was an upward trend in all S fractions in every treatment (T1 to T10), in the following order: organic > inorganic > water soluble > exchangeable S. The pot that received vermicompost coupled with BSG II (T10) (ES@ 40 kg ha-1 and MethylobacteriumthiocyanatumVRI7-A4 as S source) was found to have the greatest S-fraction and was higher than other treatments. Therefore, using BSG II in conjunction with vermicompost is necessary to preserve the availability of S nutrients in calcareous soil and increase the solubility of nutrients through S-oxidation.

A field experiment was conducted in the experimental farm of Zonal Agricultural Research Station, Dumka, Birsa Agricultural University, Ranchi, Jharkhand during kharif seasons of 2015, 2016 and 2017 to study the effects of secondary and micronutrients on rice under rice-wheat cropping system in acid soil. The experimental findings have been interpreted in terms of grain yield, crop response (%), P, K, S and B -uptake by the crop. There were seven treatment combinations viz., NPK (RD) [@ (80 : 40 : 20) kg / ha], NPK + FYM [@ 3t / ha], NPK + lime [@ 4q / ha], NPK + S [@ 30kg / ha], NPK + S + B [@ 200 ppm foliar spray as borax], NPK + S + B + Si [@ 20 kg K - silicate / ha] and (NPK + FYM + S + B + Si). The experiment was laid out in RBD with three replications. It was found that the highest grain yield (40.60 q / ha) was obtained with the combined application of (NPK + FYM + S + B + Si), which also corresponded to the maximum crop response (24.4%). It was also found that application of micronutrients alone did not have significant effects on S and B-uptakes unless they were applied in combination with FYM. The highest S-uptake (7.40 kg/ha) and B-uptake (126.03 g/ha) were recorded with (NPK + FYM + S + B + Si). The highest P-uptake (13.74 kg/ha) and K-uptake (16.11 kg/ha) were obtained with (NPK + Lime).

This experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Dhaka during 2014-2015 to know the combined effect of different levels of sulphur (S) and boron (B) on yield and yield contributing characters, nutrient and oil content of mustard and to find out the suitable combination of sulphur (S) and boron (B) for yield maximization of mustard. There were 16 treatment combinations comprising four levels each of S (S0= 0, S1=10, S2= 20 and S3= 30 kg S ha-1) and B (B0= 0, B1= 1, B2= 2 and B3= 3 kg B ha-1). It was replicated thrice in a randomized complete block design. Results showed that the combination of S and B (20 kg S ha-1 and 3 kg B ha-1) contributed positively for better performance of yield contributing characters of mustard. The combination S2B3 (20 kg S ha-1 and 3 kg B ha-1) produced the highest grain yield (2180 kg ha-1) followed by S3B2 and S3B3 treatment combination. The highest protein and oil content of mustard were recorded from S3B3 (30 kg S ha-1 and 3 kg B ha-1) treatment followed by S2B3 treatment combination. Therefore, the combination of S and B (20 kg S ha-1 and 3 kg B ha-1) might be suitable dose for cultivation of mustard in tejgaon series soils under agro-ecological zone of 28 (Madhupur Tract) Bangladesh.Bangladesh J.

Abstract The preparation of the Method for Determining Fertilizer S Recommendations for Maize based on Soil Analysis and Yield has been carried out at the Bontobili Installation, Gowa Regency, South Sulawesi, from February 2020 to May 2020. The purpose of this experiment is to find out S fertilizer recommendations based on soil analysis. The pH of the study site was <6.5, and to make a difference in soil pH, it was incubated with lime 2 t/ha to raise the pH to neutral and 4 t/ha to obtain a pH >7.5. For each soil pH condition treatment was made using a split plot group design. The main plots were given agricultural lime at a rate of 0, 200kg/ha, 400 kg/ha and 600 kg/ha.. While the sub-plots were fertilized with S, namely: 0.20,40,60,80, kg S with 3 (three) replications. All treatments will be fertilized with N and P based on soil analysis. The highest yield was obtained with lime and S fertilizer at the dose of K3S60 (600 kg/ha lime and 60 t/ha S fertilizer) showing the highest yield of 10.81 t/ha and not significantly different from the K3S80 treatment (600 t/ha lime). and fertilizer S 80 kg/ha) which is 10.64 t/ha.

In a 3-year experiment on a typic Haplustert low in soil test sulfur (S), residual effects of S applied to either soybean or wheat in a soybean–wheat system were measured for seed yields, recoveries of added S, and changes in the soil test S. Sulfur as gypsum was applied at 5 rates (0–80 kg S/ha) to soybean and 4 rates (0–60 kg S/ha) to wheat during the first year. In subsequent years the residual effects were studied in relation to fresh application of 40 kg S/ha to each crop. Seed yields of soybean and wheat were increased significantly by the application of S to each crop. The rate 80 kg S/ha applied to soybean showed residual effects in 2 succeeding crops, while 60 kg S/ha applied to soybean or wheat showed residual effect in only 1 succeeding crop. The S applied to wheat was more effciently utilised than that applied to soybean in rotation. The rates 53 and 70 kg S/ha (calculated via regression equations) applied to soybean gave 90% of the seed yield of freshly applied S at 40 kg/ha in the succeeding wheat and soybean crops, respectively, and 57 kg S/ha applied to the wheat crop gave 90% of the seed yield in the succeeding soybean crop. The recoveries of added S were greater with smaller rates of added S and were greater in the first 2 residual crops. Soil test S was adequate only in the first year and fell below critical level in the subsequent cropping period. Cumulative S uptake determined the levels of available S in the soil.

SUMMARYField experiments were conducted to test the seed yield responses of winter oilseed rape (Brassica napus L., cvs Libravo or Falcon) to the addition of different rates of S fertilizer, at three N application rates, on a sandy loam at Woburn, Bedfordshire, in 1990/91, 1991/92 and 1993/94. Large increases in seed yields, ranging from 0·7 to 1·6 t/ha, or 42–267% on a relative scale, were obtained in response to the application of 40 kg S/ha with 180 and 230 kg N/ha treatments. The effects of S were highly significant in 1991/92 (P < 0·01) and 1993/94 (P < 0·001) and close to significant (P = 0·053) in 1990/91. The yield benefits were obtained mainly from the application of the first 10 kg S/ha and further yield increases were unlikely above 40 kg S/ha. Increasing N application from 180 to 230 kg/ha decreased seed yield in 1990/91 and 1993/94, when no S was applied. In contrast, seed yield was not increased by S at zero or low (50 or 100 kg/ha) N rates. The interactions between N and S on seed yield were significant (P < 0·05) in 1990/91 but not in the other two seasons. Application of S also increased seed oil content in 1993/94, when the degree of S deficiency was particularly severe. With an application of 230 kg N/ha, the crops took up 5–22 kg S/ha at maturity when no S was applied and 26–51 kg S/ha when 40 kg S/ha was applied. The utilization efficiency of the fertilizer S ranged from 50 to 73% in the three seasons. Although the concentrations of total N in plants were largely unaffected by S treatments, large amounts of NO3-N accumulated in the leaves of S-deficient plants in 1993/94. This indicates that N metabolism was disrupted by S deficiency. The concentrations of S and the N: S ratios in different tissues and the whole plant changed considerably with time. The concentration of S in leaves at early flowering was found to be the best index in predicting S deficiency in terms of seed yield, and a critical value of 3·8 mg/g was obtained. In comparison, the N: S ratio in leaves at early flowering was a much poorer predictor of S deficiency.

A field experiment was carried out in order to study the relative efficacy of different sources of sulphur in kharif rice (Cv. Swarna Sub 1) under mid-central table land zone of Odisha. It was carried out in RBD with 10 treatments and 3 replications. Four different sources of sulphur (Single Super Phosphate, Calcium Sulphate, Elemental S0 and Navaratna as (20-20-0-13) were used with two methods of application as basal & top dressing to rice crop during Kharif season. The treatment details consists as T1 = Control (No Sulphur), T2 = Basal application (B.A) of 30 kg S ha-1 through Calcium Sulphate (CaSO4), T3 = Basal application of 30 kg S ha-1 through Elemental S ( ES ) , T4 = Basal application of 30 kg S ha-1 (through SSP) , T5 = Basal application of 30 kg S ha-1 (through 20-20-0-13) , T6 = Twice application of 15 kg S ha-1 as basal and top dressing through CaSO4, T7= Twice application of 15 kg S ha-1 as Basal application & top dressing through ES , T8 = Twice application of 15 kg S ha-1 through SSP each at Basal application & top dressing, T9 = Twice application of 15 kg S ha-1 as Basal application and top dressing through (20-20-0-13) & T10 = Basal application of 30 kg S ha-1 through CaSO4 and SSP @1:1 ratio . Significantly highest pooled mean grain yield (5.41 t ha-1) and straw yield of (5.62 t ha-1) were recorded with T7, whereas the lowest values were recorded with (control) T1 (4.1 t ha-1 & 4.31 t ha-1 respectively). Among different sources of sulphur, the grain yield of rice varied significantly and it followed the trend as Elemental Sulphur (ES) > CaSO4 > SSP > (20-20-0-13). Spilt application of sulphur fertilizer showed a beneficial effect on S uptake and translocation of micronutrients like Fe, Mn, and Zn. The sulphur economic yield efficiency ratio also inversely varied with S applications.

The effects of five training systems on tree growth, fruit yield and some fruit characteristics were assessed in Jonagold apple cv. grafted on M.9 rootstock. The trees were trained in one of five ways: slender spindle (SS; 4,761 trees/ha), vertical axis (VA; 2,857 trees/ha), hytec (HT; 1,904 tree/ha) and two different tree densities of super spindle (L-Super S with 5,000 trees/ha; H-Super S with 10,000 trees/ha). Trunk cross-sectional area (TCA) was higher in HT and VA than SS, L-Super S and H-Super S in the 4<sup>th</sup> year. While HT had the highest cumulative yield/tree, the lowest cumulative yield was observed in H-Super S. Although HT had the highest yield/ tree, it ranked the last in cumulative yield efficiency (CYE) due to high TCA. The highest (CYE) was measured in trees trained as L-Super S. When cumulative yields (CY)/ha were evaluated, the yield advantage of high density planting was clearly evident for the first three cropping years. H-Super S systems (10,000 trees/ha) had the highest CY/ha and achieved a yield of 91.24 t/ha in year 4. HT (1,904 trees/ha) had the lowest CY/ha (33.46 t). Training systems had no consistent effect on average fruit diameter, weight, firmness, soluble solid and titratable acidity.

Binding of GTP induces alpha subunits of heterotrimeric G proteins to take on an active conformation, capable of regulating effector molecules. We expressed epitope-tagged versions of the alpha subunit (alpha s) of Gs in genetically alpha s-deficient S49 cyc- cells. Addition of a hemagglutinin (HA) epitope did not alter the ability of wild type alpha s to mediate hormonal stimulation of adenylyl cyclase or to attach to cell membranes. The HA epitope did, however, allow a mAb to immunoprecipitate the recombinant protein (HA-alpha s) quantitatively from cell extracts. We activated the epitope-tagged alpha s in intact cells by: (a) exposure of cells to cholera toxin, which activates alpha s by covalent modification; (b) mutational replacement of arginine-201 in HA-alpha s by a cysteine residue, to create HA-alpha s-R201C; like the cholera toxin-catalyzed modification, this mutation activates alpha s by slowing its intrinsic GTPase activity; and (c) treatment of cells with the beta-adrenoceptor agonist, isoproterenol, which promotes binding of GTP to alpha s, thereby activating adenylyl cyclase. Both cholera toxin and the R201C mutation accelerated the rate of degradation of alpha s (0.03 h-1) by three- to fourfold and induced a partial shift of the protein from a membrane bound to a soluble compartment. At steady state, 80% of HA-alpha s- R201C was found in the soluble fraction, as compared to 10% of wild type HA-alpha s. Isoproterenol rapidly (in < 2 min) caused 20% of HA-alpha s to shift from the membrane-bound to the soluble compartment. Cholera toxin induced a 3.5-fold increase in the rate of degradation of a second mutant, HA-alpha s-G226A, but did not cause it to move into the soluble fraction; this observation shows that loss of membrane attachment is not responsible for the accelerated degradation of alpha s in response to activation. Taken together, these findings show that activation of alpha s induces a conformational change that loosens its attachment to membranes and increases its degradation rate.

ABSTRACT Crop demands for the macronutrient sulfur (S) are similar or greater than those for phosphorous. However, S is often overlooked in the management of crop fertilization. This study aimed to evaluate the effect of sources and doses of S on soybean cultivation under field conditions. A randomized block design, with 4 replications, was used. The treatments were arranged in a factorial scheme with one additional treatment (3 x 5 + 1), totaling 64 experimental units. Sources (elemental sulfur, single superphosphate and agricultural gypsum) and doses (20 kg ha-1, 40 kg ha-1, 60 kg ha-1, 80 kg ha-1 and 100 kg ha-1) of S were used, in addition to one control (without fertilizer). The following parameters were assessed: plant height at flowering, 1,000-seed weight, yield and agronomic efficiency, which were affected by the doses and sources of S; number of pods per plant, only affected by the sources of S; and number of pods with 3 seeds, with no statistical difference for any of the treatments. The highest yield recorded was 1,927 kg ha-1, at the dose of 80 kg ha-1 of S for gypsum, and the greatest agronomic efficiency was observed for the single superphosphate, at the dose of 20 kg ha-1 of S.

A field experiment was conducted to study S response of rice-peans cropping system with graded doses of S i.e. 0, 15, 30 and 45 kg ha applied in the form of SSP to rice crop. The peanut was grown as residual crop. The results of the experiment laid on a sulphur deficient (7 ppm 0.15% CaCl, extractable S) alluvial soil in Niali block of Cuttack district showed that application of S at 30 kg ha produced the highest yield of 34.3 q ha of rice grain and 21.8 q ha of peanut pod. Rice yield was 9 per cent higher and the peanut yield was 31 per cent higher than the yield recorded in control (no sulphur) treatment. Total biomass production from rice-peanut cropping sequence varied between 148.2 and 173.6 q ha. There was 17 per cent increase in biomass production due to application of 30 kg S ha. Both the crops removed 184.4 to 233.4 kg N, 20.9 to 28.6 kg P, 171 to 213 kg K, 95.8 to 127.2 kg Ca and 16.7 to 22.4 kg of S ha from soil. Highest amount of all the test nutrients were removed when both the crops received S at 30 kg ha'. At this rate of S application the recovery of N, P and K by the crops were 61, 29 and 54 per cent, respectively. The apparent S recovery (19%), shelling (57.3%) oil content (49.7%) oil yield (567 kg ha) agronomic efficiency (50.0) and value cost ratio (43.0) were the highest at this rate of S application. This suggest that 30 kg S ha in the form of single super phosphate to be the best for rice-peanut cropping system.

To establish a short rotation coppice (SRC) system in the temperate region of East Asia, planting was conducted for cuttings from seven species, including Salix eriocarpa, S. gilgiana, S. gracilistyla, S. integra, S. sachalinensis, S. serissaefolia, and S. subfragilis, with wide distribution in eastern Japan. During cultivation, cheap compost derived from swine manure and containing high concentrations of various nutrients was added. Three treatment groups, including control, low manure (5 Mg ha−1), and high manure (10 Mg ha−1) treatments, were established, and seven willows were grown for two complete growing seasons to obtain the clone density of 10,000 cuttings ha−1. The manure treatments accelerated the growth of all the willow species after two growing seasons. The averages of annual biomass production of seven willows grown under the control, low manure, and high manure treatments were 0.2 Mg ha−1yr−1, 5.3 Mg ha−1yr−1, and 8.5 Mg ha−1yr−1, respectively. By comparing with the biomasses of seven willows, the largest annual biomass production rates of 14.1 and 13.7 Mg ha−1yr−1 were observed in the high manure treatments of S. sachalinensis and S. subfragilis, respectively. For two species under the high manure treatment, S. sachalinensis had the thickest shoots, and S. subfragilis had the tallest shoots. These growth characteristics of S. sachalinensis and S. subfragilis originate from their high biomass production. Overall, these results suggest that S. sachalinensis and S. subfragilis are potentially feasible candidates for the SRC system in temperate regions of East Asia.

Fomesafen and imazosulfuron are two recently registered herbicides for use in Florida bell pepper. Field studies were conducted in 2012 and 2013 to evaluate PRE, POST-directed (POST-DIR), and PRE followed by (fb) POST-DIR control programs utilizing these new herbicides for nutsedge control in Florida bell pepper. PRE treatments included: S-metolachlor at 0.71 and 1.07 kg ai ha−1, fomesafen at 0.28 and 0.42 kg ai ha−1, S-metolachlor at 0.71 kg ha−1 + fomesafen 0.28 kg ha−1, and S-metolachlor at 1.07 kg ha−1 + fomesafen at 0.42 kg ha−1. POST-DIR treatments included imazosulfuron at 0.21 and 0.34 kg ai ha−1. PRE fb POST-DIR treatments included S-metolachlor at 0.71 or 1.07 kg ha−1 fb imazosulfuron at 0.21 kg ha−1 and fomesafen at 0.28 or 0.42 kg ha−1 fb imazosulfuron at 0.21 kg ha−1. Nutsedge control in both years at 28 d after planting was similar among all PRE treatments providing ≤ 60% control. The addition of imazosulfuron POST-DIR following S-metolachlor or fomesafen PRE provided greater control compared to S-metolachlor or fomesafen alone 14, 21, and 28 d after the POST-DIR application. Plots treated with S-metolachlor resulted in lower marketable weight and marketable fruit count compared to fomesafen in 2012; however, this was not observed in 2013. The results for these studies indicate the importance of a PRE fb POST-DIR herbicide for nutsedge control and that fomesafen or S-metolachlor PRE fb imazosulfuron POST-DIR provides growers with a viable tool capable of achieving season-long control of nutsedge in bell pepper.

The experiments were conducted in Factorial randomized block design which comprised of 25 treatment combinations in which five levels of Nitrogen (0,40,80,120 and 160 kg N ha-1) and five levels of sulphur (0,25,35,45 and 55 kg S ha-1). The experiments were laid out in the two factors RCBD with three replications, The plant height, number of branches plant-1, dry matter accumulation, seed and stover yield increased with increasing N level of 160 kg N ha-1 which was at par with 120 kg N ha-1 and while significantly superior over rest of the levels of nitrogen. On the other hand, with increasing S levels plant height, increased significantly up to 55 kg S ha-1. However, the number of branches plant-1 and seed yield and shoot yield increased up to the highest dose of S (55 kg S ha-1). Considering the combined effect of N and S, the treatment combination (120 kg n ha-1 and 45 kg S ha-1) produced the maximum seed yield (21.32 q ha-1).

Full textAbstract:
ABSTRACT Initial attachment of the cariogenic Streptococcus mutans onto dental enamel is largely promoted by the adsorption of specific salivary proteins on enamel surface. Some phosphorylated salivary proteins were found to reduce S. mutans adhesion by competitively inhibiting the adsorption of S. mutans-binding salivary glycoproteins to hydroxyapatite (HA). The aim of this study was to develop antiadherence compounds for preventing dental biofilm development. We synthesized phosphorylated polyethylene glycol (PEG) derivatives and examined the possibility of surface pretreatment with them for preventing S. mutans adhesion in vitro and dental biofilm formation in vivo. Pretreatment of the HA surface with methacryloyloxydecyl phosphate (MDP)-PEG prior to saliva incubation hydrophilized the surface and thereby reduced salivary protein adsorption and saliva-promoted bacterial attachment to HA. However, when MDP-PEG was added to the saliva-pretreated HA (S-HA) surface, its inhibitory effect on bacterial binding was completely diminished. S. mutans adhesion onto S-HA was successfully reduced by treatment of the surface with pyrophosphate (PP), which desorbs salivary components from S-HA. Treatment of S-HA surfaces with MDP-PEG plus PP completely inhibited saliva-promoted S. mutans adhesion even when followed by additional saliva treatment. Finally, mouthwash with MDP-PEG plus PP prevented de novo biofilm development after thorough teeth cleaning in humans compared to either water or PP alone. We conclude that MDP-PEG plus PP has the potential for use as an antiadherence agent that prevents dental biofilm development.

One of the main constraints for sustainable barley production is lack of information on the use of multi-nutrient fertilizers, involving the actual limiting nutrients for specific site. On farm experiment was conducted in 2016 and 2017 cropping seasons on two farmers’ field to evaluate the effect of NPS and NPSB, and to determine their optimum rates for barley production in Bulle woreda. The experiment consisted of nine treatments, including control (no fertilizer)(T1); four rates of NPS at 46 kg N. 23.5 kg P, 10 kg S/ha (T2), 69 kg N, 31 kg P, 13 kg S/ha(T3), 92 kg N, 39 kg P, 17 kg S/ha (T4), 92 kg N, 23.5 kg P, 10 kg S/ha (T5); and four rates of NPSB at 46 kg N, 23.5 kg P, 10 kg S, 1.07 kg B/ha(T6), 69 kg N, 31 kg P, 13 kg S, 1.4 kg B /ha (T7), 92 kg N, 39 kg P, 17 kg S, 1.7 kg B/ha(T8) 92 kg N, 23.5 kg P, 10 kg S, 1.07 kg B/ha (T9) were laid out in a randomized complete block design with three replications. Except the absolute control, all plots received 50 kg K/ha. Results of ANOVA indicated that application of NPS and NPBS significantly (P < 0.05) improved plant height, biomass and grain yield compared to control. NPS application at 92 kg N, 23.5 kg P and 10 kg S + 50 kg K/ha followed by NPSB at 69 kg N, 31 kg P, 13 kg S and 1.4 kg B + 50 kgK/ha recorded highest barley grain yield and resulted in 5271 and 5158 kg/ha, respectively, while the lowest yield was recorded for the unfertilized plot. In general, effects of NPS or NPSB were not significantly different, suggesting that farmers’ could invest in NPS for increased barley production. This treatment also gave higher net benefit with acceptable marginal rate of return even under projected (20%) input price increment.t Therefore, we could recommend the application of 92 kg N, 23.5 kg P and 10 kg S + 50 kg K/ha (142 kg NPS + 142 kg urea + 100 kg KCl kg/ha) for barley production in the study area. The response of barley to NPSB (inclusion of B in NPS) and NPS effect on barley with respect to RNP still needs to be widely investigated.

SUMMARYIn order to determine whether cereal crops require fertilizer sulphur (S) in areas estimated as receiving < 20 kg S/ha per year from the atmosphere, the effects of applying agricultural gypsum (10, 20, 30, 40, 60 and 80 kg S/ha), ammonium sulphate (24 and 48 kg S/ha) and foliar-applied elemental S (10 kg S/ha) fertilizers were compared with a nil-S control in replicated field experiments at 12 sites in England and Wales during 1987–90. Averaged across all S treatments, significant (P ≤ 0·01) positive yield responses of 0·4 t/ha were obtained in winter barley at three sites in 1990 on sandy soils in Wales (two sites) and in south-west England (one site). There was no yield advantage in applying > 10 kg/ha of S as gypsum at these sites. Yield responses were best predicted by a nitrogen: S concentration ratio ≥ 17:1 in leaf tissue at anthesis and a S concentration of ≤ 0·1% in the grain dry matter at harvest.Significant increases in total S and sulphate-S concentrations in leaf tissue at anthesis were obtained from increasing the rates of gypsum applied at ten of the sites, but a significant increase in the concentration of S in the grain at harvest was obtained at only one site. There was no difference in effectiveness between gypsum and foliar-applied elemental sulphur when compared at a single rate of 10 kg S/ha. Comparison of the increases in leaf-S status from maximum application rates of ammonium sulphate and gypsum suggested that ammonium sulphate was the more effective Sfertilizer source. The results confirm that S deficiency is starting to appear in cereal crops in England and Wales.

Geetanjali) produced higher rice grain yield (4065 kg ha-1) and pea seed yield (1044 kg ha-1) from aromatic rice -pea paira cropping system. However, application of STBFR + FYM @ 5 t ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 producing grain yield (3944 kg ha-1) and pea seed yield 977 kg ha-1 is another option. Application of STBFR (75 : 30 : 20 kg N : P2O5 : K2O ha-1) + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 (T10) recorded maximum gross return (Rs. 1,26,991 ha-1) , net return (Rs. 80,146 ha-1) and B : C ratio of 2.71. The increase in rice equivalent yield (REY) in this treatment was 51.4% higher than the farmer practice i,e., application of chemical fertilizers alone (40 : 20 : 20 kg N : P2O5 : K2O ha-1).

Field experiments were conducted in 2001, 2002, and 2003 to evaluate PRE applications of mesotrione at 150, 230, and 310 g ai/ha alone, and in mixtures with S-metolachlor at 1,070 g ai/ha and atrazine at 560 and 1,120 g ai/ha in corn. Corn injury was 11 to 18% with all treatments in 2002 when 3.2 cm of rainfall occurred within 10 d after PRE applications, but no injury was observed in 2001 and 2003 when rainfall was 0 and 1.1 cm within 10 d after PRE applications, respectively. Rainfall following PRE herbicide applications also influenced weed control, where weed control was generally poor with all herbicide treatments in 2001. Mesotrione at 150 g/ha controlled common lambsquarters and smooth pigweed at least 95% in 2002 and 2003, but control was 70% or less in 2001. PRE mesotrione at rates of 230 or 310 g/ha controlled common ragweed at least 83% in 2002 and 2003, but control exceeded 88% with mixtures of mesotrione at rates greater than 150 g/ha plus S-metolachlor plus atrazine at 560 g/ha. Morningglory species (ivyleaf morningglory, pitted morningglory, and tall morningglory) were not consistently controlled by mesotrione alone. In 2002 and 2003, mixtures of all mesotrione rates plus S-metolachlor plus atrazine at 1,120 g/ha controlled morningglory species at least 90%. Corn treated with mesotrione at any rate plus S-metolachlor plus atrazine at 1,120 g/ha consistently produced high yields. It is concluded that control with this three-way mixture would be most consistent with a minimum rate of mesotrione at 230 g/ha and atrazine at 1,120 g/ha.

Field experiment was conducted on baby corn (Zea mays L.) in sandy loam soil during the pre-kharif season of 2012 and 2013 at Varanasi to assess the effect of balanced fertilization (NPKS and Zn) on productivity, quality, energetics and soil health of baby corn. Results revealed that application of 125% RDF (187.5, 93.75, 75.0 kg NPK/ha) produced significantly higher yields of total baby cob yield with husk (9.55 tonnes/ha) and total baby corn yield without husk (2.15 tonnes/ha). Similarly, the higher nutrients (NPKS) and protein content in baby corn and green husk were recorded with application of 125% RDF. Among different levels of S and Zn, application of 50 kg S and 10 kg Zn/ha produced significantly higher yields of total baby cob with husk (9.38 and 9.24 tonnes/ha) and total baby corn without husk (2.15 and 2.10 tonnes/ha), respectively. Further, the crop fertilized with 50 kg S and 10 kg Zn/ha increased the nutrients (NPKSZn) and protein contents in babycorn and green husk but it was noted being on a par with application of 25 kg S and 5 kg Zn/ha. In terms of energetics, the higher values of energy inputs (20.71 x 103 MJ/ha), energy returns (226.98 x 103 MJ/ha), net energy returns (205.98 x 103 MJ/ha), energy use efficiency (10.80), energy productivity (0.454/kg/MJ), human profitability (65.20), energy productivity (9.80), energy intensiveness (0.354 MJ/Rupees), energy output efficiency (3.78 x 103 MJ/ha/day) and energy intensity in economic terms (3.82 MJ/Rupees) were recorded with application of 125% RDF and the lowest with 100% RDF. Similarly, application of 50 kg S and 10 kg Zn/ha gave the highest values of energy inputs (18.33 and 17.91 x 103 MJ/ha), energy returns (223.12 and 219.69 x 103 MJ/ha), net energy returns (203.31and 200.09 x 103 MJ/ha), energy use efficiency (11.25 and 11.19), energy productivity (0.473 and 0.471 kg/MJ), energy intensiveness (0.330 and 0.328 MJ/Rupees), energy output efficiency (3.72 and 3.66 x 103 MJ/ha/day), energy intensity in economic terms (3.71 and 3.67 MJ/Rupees), human energy profitability (64.09 and 63.11) and energy profitability (10.25 and 10.19), respectively as compared to its preceding doses. The highest actual loss of S and Zn were recorded with application of 125% RDF, 50 kg S and 10 kg Zn/ha whereas, the maximum positive balance of S and Zn were associated with 50 kg S and 10 kg Zn/ha, respectively.

Full textAbstract:
A field study aimed to evolve efficient nutrient management for improving yield and quality of sesamum was conducted during pre-rabi season of 2022. The experiment was laid out in a factorial randomized block design replicated thrice with twelve treatments. Treatments consisting of two levels of nitrogen (25 and 50 kg/ha), two levels of phosphorus (12.5 and 25 kg/ha) and three levels of sulphur (0, 20 and 30 kg/ha). Seed and stover yield as well as total nutrient uptake were recorded significantly higher with the application of 50 kg/ha N, 25 kg/ha P and 30 kg/ha S. The application of 50 N and 30 kg S was recorded significantly higher oil content and oil yield over the rest of the nitrogen and sulphur levels. N content in seed (3.13%) and stover (1.226%) were found significantly influenced by 50 kg/ha N. Phosphorus @ 25 kg/ha was recorded significantly higher P content in seed (0.493 %) and stover (0.392%).S content in seed (0.325%) and stover (0.171%) were found significantly influenced by 50 kg/ha S. Significantly higher available nitrogen (281.22 kg/ha) was found under application of nitrogen @ 50 kg/ha. Significantly the higher residual phosphorus (28.81 kg/ha) was obtained with the application of 25 kg P/ha. Significantly the higher residual sulphur (7.63 mg/kg) was obtained with the application of 30 kg S/ha.
