Full textAbstract:
Owing to the agriculture intensification increasing, unreasonably extensive use of chemicals, comprehensive mechanization, intensive tillage, together with an increase in productivity leads to noticeable undesirable results. The contamination grow, the infectiousness of fields by pests and diseases of agricultural crops increases, due to decomposition of humus, the soil fertility gradually decreases, and the quality of the products is deteriorating by the presence of hazardous compounds for health, ecological balance is disturbed environment. In this connection, so that to solve these problems, it is necessary to develop farming biologzation, namely the expansion of perennial grasses, reducing the use of fertilizers, pesticides and other chemicals, the use of intermediate crops for fodder and green manure, the use of crop residues and organic fertilizers, the use of advanced tillage methods. In recent years, the study of some specific biologzation elements are held in Russia too, but without an integrated approach. An intensification of the use of biological means of soil fertility was contributed to: creation an optimum density of the addition of the soil; creation better moisture content of crops; phytosanitary condition of crops. The maximum crop productivity (4.03 tons per hectare) was obtained, when adding straw and stubbly green manure, the cost of 1 ton of grain was decreased, compared with mineral background to 281.4 rubles, the net income was higher to 1593.6 rubles per hectare, the profitability of oat production was 52.8%, against 32.5% on a mineral background.

Full textAbstract:
Seed yields, yield components, pest incidence and damage were examined in two field experiments of mixed intercropping of oats (Avena sativa) with field beans (Vicia faba) in Southern Finland in 1984—1985.The stand types were monocrops and replacement series of mixtures with 2/3 and 1/3 or 1/3 and 2/3 of oats and beans, respectively, on plots treated or not treated with insecticide. In the first season when the overall performance of the crops was poor and the numbers of the main pest Rhopalosiphum padi (Horn., Aphididae) on oats low, the Land Equivalent Ratio (LER) index indicated an intercropping advantage in the bean yield and a disadvantage in the oat yield, the insecticide treatment having no effect on the overall nor on the relative performance of the component crops. The site used during the second season was of high fertility, thus favouring oats over beans. The LERs indicated no advantage or disadvantage in mixed cropping for either oats or beans when R. padi was not controlled. Spraying against R. padi improved the performance of oats, the mixture with 1/3 oats showing an advantage over the monocrop. Simultaneously, there were signs (p = 0.08) of a reduction in the relative performance of the beans. The indicative results support the hypothesis of interspecific dynamics in compensatory yielding as an element of improved reliability in intercropping. The yield components most sensitive to the change in cropping pattern were the number of panicles per plant in oats and the seed weight in beans, both increasing in the mixtures. Compared to known responses to stand density in monocrops, the beans responded to the mixed cropping in a more specific way than the oats. Mixed cropping increased the numbers of aphids in oats. There were signs of a reduced incidence, but not of a reduced average colony size, of Aphis fabae, and of a reduced rate of notching by Sitona spp. weevils on beans in mixed cropping. The results for damage by the frit fly (Oscinella frit) were inconclusive.

The purpose of the article – to perform comparative analysis of the economic effectiveness of the 10 samples of organic fertilizer of pig farm, bio humus “Humivit” and mineral fertilizers (Nitroamofoska, ammonium nitrate, carbamide) on the example of oats. The study used the following methods: abstract-logical, cash-analytical, cash-equivalent, expert, monographic. The research was done in Ukraine. The results of the comparative analysis of economic effectiveness of the 10 samples of organic pig fertilizer, bio humus “Humivit” and mineral fertilizers (Nitroamofoska, ammonium nitrate, carbamide) in the example of oats on the green mass show that the use of organic fertilizers sample number 1, 2, 3, 4, 5, 6, 10 is an economically effective, while organic fertilizers of sample number 7, 8, 9 are economically inefficient. By the main indicators of economic effectiveness (coefficients of payback, conditional additional profit, level of profitability) organic fertilizers sample number 1, 2, 3, 4, 5, 6, 10 have significant competitive advantages over the studied brands of mineral fertilizers and bio humus “Humivit”. The use of organic pig fertilizers, except the sample number 8, in economic terms for the impact on potential soil fertility is more effective than bio humus “Humivit”. The most significant economic benefits for the impact on potential soil fertility are samples of organic fertilizers pig number 1, 5, 10, whose application generates the lowest cost price of humus. The element of novelty is that with using the author’s scientific and methodical approach it was conducted the estimation of economic effectiveness of the liquid organic fertilizer of pig farm for the impact on potential soil fertility.

Abstract. The purpose of the study was to study the influence of biologized crop rotation with six fields by 50 %, saturated with legumes, on soil fertility and crop productivity on typical sod-podzolic light loamy soils of the Upper Volga. As a result of field experiments and laboratory studies, new data and knowledge about the effect of crop bipolarization on its productivity and the properties of sod-podzolic soil were obtained. For the first time in the region, it has been studied and established that use of legumes in the crop rotation instead of organic fertilizers partially contributes to the replenishment of the soil with organic matter and nitrogen in the form of organic residues and nodule bacteria, which leads to a decrease in the degradation of soil fertility or even to some improvement. By the end of rotation of the crop rotation when applying (NPK) 90 kg/ha compared with the control version (without NPK), in the biologized crop rotation, the humus content increased by 0.14 %, the acidity of the soil solution slightly decreased by 0.25 units, the content of nitrate nitrogen increased by 59 %, mobile phosphorus – by 72.8 % and exchange potassium – by 70.4 %. The density of soil compaction as a whole in a layer of 0–20 cm in occupied steam, under spring wheat and oats amounted to 1.22–1.24 g/cm3, in other crops (where treatment was not carried out for 2 years) – 1.35–1.39 g/cm3. Mineralization of flax tissue more actively occurred under clover 1st and 2nd years of use – 35.6–42.7 % and 31.0 and 37.3 % and in the employed (vetch-oat) – 26.5–34.4 %, less intensively under winter wheat – 20.9–27.5 and oats – 20.1–25.2 % and very weakly under spring wheat – 13.0–16.5 % at the control and the level of mineral nutrition, respectively. There were fewer weeds in winter wheat sowings – 84 pcs/m2, since it is more competitive with them, oats – 112 pcs, clover – 131 pcs, in a couple – 124 pcs and spring wheat – 138 pcs/m2. Productivity of crops to a greater extent was determined by the applied fertilizers. In fertilized plots, compared with the control, the productivity of the oatmeal mixture was 36.2 % higher, spring wheat – 24.4 %, clover 1st year of use – by 36.2 %, 2nd year of use – by 45.7 %, winter wheat – by 25.7 % and oats – by 30 %.

The article represents scientific and methodological approach to the problem of rational agricultural land use system formation (RALUS) based on soil fertility recreation theory. The main methods of research: system approach to the analysis of subject matter, theoretical generalization of the problem condition. The basis of approach to RALUS formation is the algorithm of soil fertility estimation, represented by a number of parameters, determining soil fertility, used in technological land use systems, determined by the main regional evolutional and ecological and genetic conditions for formation and recreation of the fertility level of the given soil types. The final estimation of agricultural land fertility level - the backbone of the RALUS economy of the municipality, is based on the calculation of productivity – getting the average values of biomass per unit area at the 8-10 most common cultivated crops and their mixtures (wheat, barley, oats, rye, peas, buckwheat, canola, rump, alfalfa, clover, etc.) in specific soil-climatic zone. As a result of the research, there were formulated the basis and content of the scientific and methodological approach to the estimation of the agricultural land fertility (productivity) level, as well as recommendations for the formation of zonal RALUS on the example of the Novosibirsk region, the use of which makes it possible to more reliably use (according to 3-5 years) the crop potential of the land fund of the economy, district, region.

Relevance and methods. The optimal selection of precursors and methods of biologization can increase the return of organic matter to the soil, increase the yield and productivity of crops. Corn was studied on irrigation, and crops (sorghum, oats, winter wheat) in crop rotation were studied on the bogar. To elucidate the general patterns of plant development in the system of forest strips and in experimental fields (bogar), statistical processing of the research results was used in the Exel and Statistica software packages, which is based on the generalization and synthesis of the results, which makes it possible to reach forecasts of plant development during the growing season. The soil is light chestnut, heavy loamy, with a humus content in the arable layer of 1.74%, the pH of the soil solution is 8.1. The content of easily hydro-lyzable nitrogen is low — 3.2–3.9 mg/100 g of soil, average phosphorus mobile — 2.1–3 mg and exchange potassium increased — 30–40 mg/100 g of soil. The amount of average annual rainfall is 339.7 mm.Results. A study of the data showed that regardless of crop rotation the maximum content of nutrients (nitrogen, phosphorus, potassium) was observed in the tillering phase, then decreased. The correlation coefficient on irrigation shows the tightness of communication over the entire array and gives grounds to use the approximation of the multiple regression equation as predictive in the system of forest stripes on irrigation: Y = a + b1 Х1 + b2X2 and on the dry land: Y = a + b1X1 + b2X2 + b3X3. In dry years the yield of grain crops (corn, sorghum, oats, winter wheat) ranges from 0.59 to 1.73 t/ha. In wet years the yield of grain crops increases to 4.95 t/ha. With the help of programs you can calculate the amount of fertilizer for a given yield and manage the bioproductivity of crops in the system of forest belts and on the dry land. The importance of soil fertility in managing bioproductivity is based on the optimal selection of precursors and methods of biologization, which can increase the yield of grain crops. The scope of the recommendations is the Lower Volga soil zone.

Background: It is the fact that, India consists of world’s largest tobacco chewer population, more prevalent in low income group. The effects of tobacco chewing on semen parameters have been widely studied. The study aim is to analyze the semen analysis parameters (oligozoospermia, asthenozoospermia, teratozoospermia, oligo-astheno-teratozoospermia -OATS and azoospermia) of tobacco chewer and non chewer infertile patients.Methods: A retrospective analysis of 639 patients was done out of which 150 were non-chewers and 489 were tobacco chewers. The percentage of population with particular semen abnormalities were compared between the two groups. The same comparison was performed between tobacco chewing primary infertility and secondary infertility patients in order to specifically assess the effect of tobacco chewing in sub-fertile patients.Results: OATS and azoospermia cases were significantly higher in the tobacco chewing infertile patients as compared to oligozoospermia, asthenozoospermia and teratozoospermia cases. In case of sub-fertile patients also, the percentage of OATS and azoospermia were significantly higher.Conclusions: This finding suggest that tobacco chewing greatly affects every parameter of sperm i.e. concentration, motility and morphology collectively. Moreover, tobacco chewing may be less affecting the male fertility initially but prolonged exposures affects detrimentally resulting in serious semen parameter abnormalities such as OATS and even azoospermia. And such cases are difficult to treat even with higher and advanced infertility treatment options like ICSI, microfludics, etc. This reduces the chances of IVF success as well as increases the financial burden on the patients undergoing infertility treatment. Thus, infertility clinics must employ awareness programs for such patients to explain them the effects of tobacco chewing habit and reducing it can definitely enhance the treatment outcomes.

The change in the microbiological activity of sod-podzolic sandy loam soil when using coffee waste and sewage sludge as a fertilizer for oats in comparison with traditional fertilizers is considered. During the study, it was determined that the predominant groups were bacteria and actinomycetes. Bacilli and fungi are few in number. The introduction of sewage sludge and coffee waste into the sod-podzolic sandy loam soil at a dose of 10 t / ha increases the activity of the microflora of the sod-podzolic sandy loam soil, which increases the effective and potential fertility.

Full textAbstract:
A field experiment was conducted to evaluate the yield and quality parameters of oats (Avena sativa L.) at forage research farm in Punjab Agricultural University, Ludhiana. Four different nitrogen levels viz. 0 (control), 50, 75 (recommended) and 100 Kg N/ha were applied in the form of urea. Samples were collected at three different growth stages i.e. 30, 45 and 60 DAS. As the growth of plant continued decrease in total nitrogen (45%), non protein nitro-gen (37%), ether extract (13%), ash content (24%) and digestibility (23%) was observed. But increase in free amino acids (48%) and cell wall constituents i.e. ADF (19%), NDF (31%) and CF (34%)with plant’s growth was reported. The interactive effect of varying levels of inorganic fertilizer application on the chemical composition of the plant at various growth stages revealed an increase in total nitrogen (18%), non protein nitrogen (26%), ether extract (18%), free amino acids (32%), ash content (13%) and digestibility (7%) with increase in fertilizer level however ADF (7%), NDF (2%) and CF (3%)content decreased with increased levels of nitrogen fertilization. Correlation studies showed that significant negative correlation was present forin vitro dry matter digestibility with acid detergent fiber (r= -.861**), neutral detergent fiber (r= -.891**) and crude fiber (r= -.740**) at recommended dose of N fertilization. The objective of this study was to investigate the effect of different doses of nitrogen fertilization at different growth stages on quality components in oats fodder.

Collecting additional data to calibrate and refine current guidelines for interpreting soil and plant test values for P is an ongoing need in Arizona. An experiment was conducted at the Safford Agricultural Center during the 1987 -88 crop year to evaluate the response of 'Aldura' durum wheat to P fertilizer applications on a clay loam soil testing low in available P. Maximum grain yields of more than 5,500 lbs. /A were obtained by banding 40 lbs. P₂O₅/A as triple super phosphate with the seed at planting. A December 9 planting date subjected plants to cold soil temperatures early in the season (up to 80 days after planting), rendering soil P less available for plant utilization. Preplant soil P analyses predicted the yield increase observed with P fertilization (11.2 %);however, economic returns were not sufficient to offset the cost of P fertilizer. The recommended preplant soil test for P proved accurate in predicting P status and stem PO₄⁻P tissue analyses seemed reliable in monitoring P nutrition of durum wheat. A critical nutrient range of 1200 - 2000 ppm PO₄⁻P is proposed for basal stem tissue sampled prior to the joint growth stage, and 1500 - 1706 ppm PO₄⁻P is suggested for flag leaf tissue sampled at the boot stage.

Full textAbstract:
The procedure currently recommended by the University of Arizona for predicting the nitrogen (N) requirements of durum wheat has proven to be quite accurate at sites where grain yields exceeded 5,400 lbs/acre. However, the method slightly overestimated N needs when the yield possibility was below that level. Additional information on the relationships between N rates, stem NO₃⁻N levels and grain yields are needed for the wide range of agronomic conditions found in Arizona. Three N fertility trials were conducted at the Maricopa Agricultural Center to: 1) document the accuracy of the currently recommended soil + stem NO₃⁻N testing procedure in predicting the N needs of durum wheat on soils of varying residual N content and grain yield potentials; and 2) to evaluate the use of the current stem testing procedure on two durum varieties 'Aldura' and 'Westbred -881. The University of Arizona procedure was found to accurately predict the minimum amount of N required for optimum production of durum wheat on two sites where yield potentials were 5,400 and 4300 lbs. grain /A, but it slightly overpredicted N rates on two sites with maximum yield levels of 5,400 lbs /a. 'Aldura' consistently out yielded 'Westbred -881' by about 12 % but 'Aldura' also averaged 0.78 %lower in grain protein content. Little statistical or practical differences were observed in the quantities of NO₃⁻N contained in the stem tissue of these two varieties, which should simplify the interpretation of stem NO₃⁻N values for various wheat cultivars. The currently recommended procedure for predicting optimum N rates in durum wheat production has proven to be accurate when yield levels exceed 5,400 lbs. grain /A. A slight modification of the procedure may be needed to more closely predict N requirements on lower yielding sites.

The relative efficiencies of residual soil NO₃⁻N and fertilizer Nin basin - irrigated wheat production are not well defined. A two-year field study was conducted at the Safford Agricultural Center to investigate what these N efficiencies are under optimum yielding conditions. 'Aldura' durum wheat was grown on the same field site two years in succession. In 1987 a wide range of fertilizer N (0 to 419 lbs /A) applications resulted in residual NO₃⁻N accumulations of 36 to 140 lbs /A in the surface four feet of soil. Residual N plots were split in 1988 with one subplot receiving no additional N while the other was treated with 145 lbs of fertilizer N /A. Grain yield response curves for the –N and +N subplots were used to estimate the marginal rate of substitution (MRS) of soil NO₃⁻N for fertilizer N. The marginal efficiency of residual NO₃⁻N was a constant 16.7 lbs. grain produced /lb. of N across the range of profile N values in this study, while the marginal efficiency of fertilizer N varied from over 17 to below 6 lbs. grain /lb. N. When basin- irrigated wheat is supplied with adequate, but not excessive N, the MRS of soil vs. fertilizer N is about 1:1 although absolute N efficiencies under basin irrigation are considerably lower than those achieved in other grain production systems.

Full textAbstract:
Under conditions of East Siberia, the positive effect of sainfoin on the fertility of gray forest soil and the introduction of this crop into fodder five-course rotations have been studied. In Siberia the Hungarian sainfoin (Onobrychis arenaria) is well-spread. As a control variant the crop rotation without perennial legume crops (sainfoin-free) was taken. Our research on the introduction of a new legume crop — sainfoin has shown that the content of mobile phosphorus, on the average in crop rotations, varies from 15.3 to 17.1 mg per 100 g of soil, the value of the nitrate nitrogen indicator — from 21.5 to 25.3 mg/kg. The intake of organic matter into the soil, due to a green manure — sainfoin — increases the humus content to 4.8–4.9 %. The rise in the yield of cultivated grain-forage crops after perennial legumes has been proved. Thus, the yield of pea-oats amounted 2.0–2.4 t/ha feed units. Among the crops harvested for green mass corn was more productive. It provided 1.8–2.2 t/ha of feed units. Pea-oats gave less productivity — from 1.5 t/ha of feed units in a control variant to 1.8 t/ha of feed units in the variants with sainfoin. The yielding capacity of sainfoin was 2.1–2.2 t/ha of feed units. The average yield for crop rotations with sainfoin was higher than the control by 16.6 %. Taking the obtained data into account, it may be concluded that all three five-course crop rotations are productive, the best, according to all criteria, is the variant with two fields of sainfoin providing the decline in cost price up to 3529.9 rub. one feed unit, the high level of pure income 11848 rub./ha and the biggest coefficient of energy efficiency — 3.0
