Abstract:

A field experiment was conducted to study the effects of irrigation and nitrogen applied at different growth stages on the oil and anethole yields of fennel (Foeniculum vulgare Mill.), and its yield components. Irrigation increased the yield of whole plant dry matter, with the stem elongation stage being the most sensitive. Full irrigation and irrigation applied during the flowering and late flowering growth stages increased umbel and oil yields. Irrigation during the late flowering stage made the greatest contribution to oil yield, accounting for >80% of the yield due to full irrigation. This was attributed to the concurrent timing of irrigation during the late flowering stage with dry conditions and the development of the main oil-bearing structures, the secondary and tertiary umbels. Irrigation had no significant effect on the anethole concentration of the oil. The best economic return was achieved by irrigating during the late flowering stage. There was no significant effect of nitrogen on any of the yield components measured in this study.

Abstract:

To understand and describe the behavior of charge dynamics in mills, a series of dry and wet grinding tests were performed on a laboratory-scale ball mill. The comparisons between experimental results and grinding media trajectory simulations were addressed. Results show that the grinding media trajectory simulations exhibit a good agreement with the experimental results. The shoulder angle was proportional to mill speed and ball filling. The toe angle was inversely proportional to ball filling, but the impact point angle was appeared to invariant to ball filling and inversely proportional to mill speed. By means of motion analysis of the charge, a good grinding efficiency can be obtained when the ball filling ranging from 20% to 40% and the mill speed ranging from 70% to 80%. For dry tests, the orthogonal analysis indicates that the influence order of four factors on power-mass ratio is ball filling, mill speed, powder-grinding media ratio and lifter profile and the influence order of four factors on −0.074 mm yield is mill speed, ball filling, powder-grinding media ratio and lifter profile. The best dry tests are a combination of 70% of critical speed, 20% of ball filling, 0.8 of powder-grinding media ratio and waveform lifter. Correspondingly, the power-mass ratio can increase by 28.27% and the production of −0.074 mm can increase by 50.38%. For wet tests, the variations of −0.074 mm yield on mill speed and moisture content increase up to a maximum and then decrease rapidly. The −0.074 mm yield can reach a maximum at the 80% of mill speed and 50% of moisture content.

Abstract:

Introduction. Birch bark contains biologically active substances (BAS). In this regard, the search for ways to increase yield of its bioactive agents is relevant. Aim. To study the effect of birch bark grinding methods on the extract of its BAS during extraction. Materials and methods. Samples of birch bark of silver birch (Betula pendula Roth.) and downy birch (Betula pubescens Ehrh.) were ground up on devices with various force effects on plant material — disk (mainly squeezing, shear, tensile and shearing forces), three-roll annular (crushing and abrasive forces) and ball (crushing, abrasive and shock-shear forces) mills. Morphological and microscopic studies were carried out, the content of extractive substances and moisture in the ground up samples was determined. The composition and content of BAS were analyzed. Results. The smallest changes in the morphological and anatomical structure of plant material were observed when using a disk mill (the morphological features of birch bark and its cellular structure are preserved), grinding on three-roll ring and ball mills leads to serious changes in the morphological and anatomical structure of birch bark (the morphological and anatomical structure is lost, cell walls are destroyed). Comparative analysis of the yield of extractive substances from ground up birch bark samples, depending on the grinding method and the extractant used (purified water and ethyl alcohol of different concentrations: 96, 80, 70, 40, 20 and 10%) showed that the best extractant is 80% ethyl alcohol. The highest yield of extractive substances was noted for a sample of birch bark ground up in a ball mill — 36.85%, for ground up in a disc mill — 29.96%, on a three-roll ring mill — 30.88%. When studying the yield of the main groups of BAS (saponins, tannins, coumarins, hydroxycinnamic acids) from ground up birch bark samples, it was found that when using grinding methods that do not lead to the destruction of cell walls, the yield of BAS is limited by the capillary-porous structure of the plant material. Conclusion. When using grinding methods that lead to the destruction of cell walls, the greatest yield of BAS from birch bark is observed in the case of using a more severe impact on it, including not only abrasion, crushing, but also impact (ball mills).

Abstract:

In two-year trials taking place at the Faculty of Horticulture in Lednice (Mendel University of Agriculture and Forestry in Brno), three cultivars of sweet fennel (Foeniculum vulgare Mill. ssp.vulgare var. azoricum [Mill.] Thell) – Precoce di Bologna, Rudy F1 and Zefa Fino have been evaluated. The trials were conducted in two terms in each of the trial years (summer and autumn term). In the harvest time, nutritional value was evaluated: content of vitamin C, minerals (K, Na, Ca, Mg), dietary fibre, dry matter and nitrates. Besides, the weights of pseudobulbs and its yield have been evaluated. The content of the monitored substances ranged in the following intervals: vitamin C 87–347 mg/kg, K 4,241–5,851 mg/kg, Na 77–512 mg/kg, Ca 56–363 mg/kg, Mg 82–389 mg/kg, dietary fibre 5.75–7.59 g/kg, dry matter 61–75.8 g/kg, nitrates 650 to 3,767 mg/kg, weight of pseudobulb 199–383 g. A significant influence of cultivar on K content has been observed; furthermore, growing term markedly influenced the content of vitamin C, K, Na, Ca, Mg, dietary fibre, nitrates and on weight of pseudobulb. A significant influence of year on the content of vitamin C, Ca, Mg, dietary fibre, dry matter, nitrates and weight of pseudobulb has been recorded as well. From the three tested cultivars, Zefa Fino showed significantly higher average yield (331 kg/100 m2) in summer terms and Rudy F1 (267 kg/100 m2) in autumn terms.

Abstract:

Efficient lumber utilization at the saw has become a key issue in the woodworking industry. This is because of shrinking supply and increasing raw materials prices. In this paper, formulation of the cross-cut first method of cutting defects out of lumber as a one-dimensional stock cutting problem is discussed. A Monte-Carlo simulation method has been used for generating boards of a given grade. This simulation greatly aids in comparing alternate solution procedures proposed in the paper. To facilitate real time-application, a fast heuristic for the digital computer is introduced. This is followed by a discussion of cutting length priority allocation. The heuristic solution is compared with the optimal solution obtained using Kolesar’s knapsack algorithm.

Abstract:

The possibility of using sugar mills wastewater/effluent in irrigation was evaluated by investigating the effects of wastewater on growth and yield of wheat (Triticum aestivum cv. Prodip). The experiment was conducted at North Bengal Sugar Mill site in Natore during December 2011 to March 2012. Three irrigation treatments (I1: irrigation with fresh/tubewell water, I2: irrigation with a mixture of fresh and wastewater at 1:1 ratio and I3: irrigation with wastewater) under a main factor and three fertilizer treatments (F0: no application of fertilizer, F1: half dose fertilizer and F2: full dose fertilizer) under a sub factor were evaluated. The experiment was laid out in a split-plot design with three replications of the treatments. Wheat was grown with three irrigations totaling 14 cm applied at 4, 26 and 43 days after sowing (DAS). Important growth and yield data of the crop were recorded. The highest grain yield of 1.829 t/ha was obtained under mixed water irrigation and the lowest grain yield of 1.469 t/ha was obtained under wastewater irrigation. The three irrigation treatments, however, provided statistically similar (p = 0.05) grain yield. For the interaction between irrigation and fertilizers, mixed water irrigation and full dose fertilizer application (I2F2) provided significantly higher grain yield (2.757 t/ha) than all other treatment combinations. The second highest yield, produced under freshwater irrigation and full dose fertilizer (I1F2), was statistically similar to the yield under wastewater irrigation and full dose fertilizer (I3F2). Results of this experiment thus exposed good prospects of irrigating wheat by sugar mills wastewater.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19174 Progress. Agric. 24(1&2): 211 - 218, 2013

Abstract:

The use of microbial inoculums can improve growth and yield of plants without use of agrochemicals which can result in obtaining quality food. Rocket is widely grown for spice and salad in the areas of Mediterranean Sea. Having in mind the importance of rocket in human diet the research was carried out in rocket grown in unheated protected houses. The experiment included four variants as follows: variant 1 control – untreated variant; variant 2 – treated with application of inoculum from the product Uniker into the soil before the sowing of the rocket; variant 3 – treated with application of inoculum from two different products Uniker and Slavol S before sowing of the seeds, whereby Slavol S was applied by immersion of the seeds for five minutes before sowing, and Uniker was applied in the soil before the sowing of the rocket; variant 4 – treated with foliar application of live cells of bacteria Azotobacter sp. (10-6 cfu/ml) every fifteen days during vegetation. During the vegetation total yield (t/ha) and yield components were measured. The results showed that the highest average yield (22,30 t / ha) was achieved by variant 4. Also the highest average value for the weight of the whole plant (4,22 g), root weight (0,50 g), rosette weight (3,73 g) and leaves weight (2,50 g) was obtained by variant 4. The highest average value for the number of leaves was measured in variant 3 (6,13) while the root length was highest in control variant (116,70 mm).

Abstract:

Organic amendments have been shown to increase sugarcane yield on sand soils in Florida. These soils have very low water and nutrient-holding capacities because of the low content of organic matter, silt, and clay. Because of high costs associated with broadcast application, this field study was conducted to determine sugarcane yield response to furrow application of two organic amendments on sand soils. One experiment compared broadcast application (226 m3 ha−1) of mill mud and yard waste compost, furrow application (14, 28, and 56 m3 ha−1) of these materials, and no amendment. Another experiment compared furrow applications (28 and 56 m3 ha−1) of mill mud and yard waste compost with no amendment. There were significant yield (t sucrose ha−1) responses to broadcast and furrow-applied mill mud but responses to furrow applications were not consistent across sites. There were no significant yield responses to yard waste compost suggesting that higher rates or repeated applications of this amendment will be required to achieve results comparable to mill mud. Results also suggest that enhancing water and nutrient availability in the entire volume of the root zone with broadcast incorporation of organic amendments is the more effective approach for low organic matter sands.

Abstract:

Plants of nine tomato cultivar (Lycopersicon esculentum Mill.) of contrasting breeding origins where grown under two growing systems using the nutritive film technique (NFT) and a peat substrate. Planting density was 3 plants m−2. Yield of marketable fruit, culls and four fruit quality parameters (texture, colour, titratable acidity and total soluble solids) were measured at harvest and over 28 d post-harvest. Two varieties were used: Trust, one of the most popular cultivars in Canada, and Cencara a newly released cultivar with long-keeping quality. Over a 21-wk harvest period there was no significant difference for yield or for post-harvest characteristics between the two growth substrates. Trust produced highest yields, compared to the other cultivars, followed by Bounty with a yield 1.6 kg m−2 lower. Bounty and Panther yielded significantly greater masses of marketable fruit than the other cultivars. The new cultivar Cencara showed significantly lower total and marketable yields than the other cultivars, because of the small size of its fruit. At harvest and in storage, Cencara showed better keeping qualities than Trust, while the latter had better eating qualities. Key words: Peat substrate, nutritive film technique, tomato, Lycopersicon esculentum Mill.

Plant height, number of leaves and number of branches, days required for first flower initiation, days required for 50% flowering, days required for fruit setting, fruit cluster plant-1, fruit plant-1, weight tomato-1, yield plant-1, yield plot-1 and yield hectare-1 were significant influenced by the combined application of IAA and varieties of tomato. BARI Tomato-7 had the highest fruit yield with 100 ppm IAA and the lowest yield was observed in Ratan with 0 ppm IAA. IAA treated plots showed better performance for growth parameters and yield compared to control condition and 100 ppm IAA was more suitable than the 200 ppm IAA for higher yield of tomato cultivation. Among the treatment combinations, BARI Tomato-7 with 100 ppm IAA was superior, Ratan with 0 ppm IAA was inferior and BARI Tomato-7 with 200 ppm IAA, Manik with 200 ppm IAA and Ratan with 200 ppm IAA treated plots showed the intermediate results for yield and yield components.J.

SummaryCrosses between two cultivars of tomato (Lycopersicon esculentum Mill.), and two accessions of the wild species L. pimpinellifolium (Jusl.) Mill, were made and F1, F2 and backcross generations were developed and studied. Significant differences in number of fruits per plant, yield per plant and fruit weight were found between means of the different generations. Variation in number of fruits per plant and yield was also found between plants within generations. Number of fruits per plant was a highly heritable character (average h2 = 73·6%) and closely correlated with yield per plant, indicating that it may be a suitable selection criterion for yield improvement in tomato crosses.

Full text

Abstract:

Variability in wood properties has a major impact on pulp quality and the cost associated with pulp production. Frequently, accounting data for green tons of wood across the mill scales and the tons of pulp produced suggest that the pulp mill has affected the pulp yield because the tons of purchased wood divided by the tons of pulp produced changes. The current work examines the impact of the time — from when a tree is harvested in the forest to the time it is brought across the scales at the mill — on accounting yield and operating cost. Percentage weight loss (assumed to be changes in moisture content) were determined for Pinus taeda, Eucalyptus dunni, and Eucalyptus grandis over a 12-week period in the winter and summer seasons. Wood samples were obtained immediately after being harvested. The percentage weight loss within the first 5 days of storage varied from 2% to 13%, depending upon species and season, and reached 36% after 11 weeks of storage. For a 1000 tons/day mill with a 55% pulping yield on o.d. fiber, the difference between using fresh-cut wood verses cut trees that have been stored for 11 weeks is 1130 green tons. Assuming the mill pays $45/green ton, the change in green log usage between fresh-cut and 11-week-old logs can cost the mill US$50,850 per day.

Abstract:

Over the course of a year, mills experience substantial variations in reported pulp yields per green ton of wood. In the spring, more wood must be consumed to produce the same amount of good-quality pulp. This paper examines the extent of seasonal changes and the seasonal reproducibility of wood moisture in chips. Seasonal changes in the amounts of bark, pin chips, and fines in the chips going to the digester are also examined. Other potential seasonal accounting impacts on reported pulp yield and costs are also considered. Assuming a 1000-TPD mill with a nominal wood cost of $45/green ton, these seasonal changes can account for a variance of almost $600,000/month between the best and the worst operating month. In the worst month, an additional 0.5 green tons of wood per ton of pulp must be processed.

The treatments were 5 x 2 factorial combinations including five rates of PBZ (control, 1 kg ha-1, 2 kg ha-1, 3 kg ha-1and 4 kg ha-1) and two times of application (at 2 to 4 and 6 to 8 true leaf growth stages of tomato seedlings), arranged in a Randomized Complete Block Design, each treatment replicated three times. The objective of the study was to characterize the effect of rate and time of application of PBZ on the yield and yield related parameters of tomato. Time and rate of application of PBZ significantly increased harvest index, yield concentration and index of economic earliness, and decreased fruit set percentage, pericarp thickness, fruit diameter and percentage of class one fruit. Irrespective of the time of application, an increase in the rate of PBZ compared to the control significantly increased days to fruit maturity. Time and rate of application of PBZ were significantly interacted to increase; unmarketable fruit yield but decrease means fruit weight. Compared to the control, the interaction effects also produced two significant trends of variations on fruit yield per plant, fruit dry weight per plant, marketable fruit yield and total fruit yield. Significant reduction in yields was observed for diluted concentrations like 1 and 2 kg/ha a.i. of PBZ in the second time of application and 1 kg/ha a.i. of PBZ in the first time of application, whereas all other treatments produced significantly higher yields than the controls. On the contrary, time and rate of application of PBZ were found to be effective in improving economic earliness of tomato. As a whole, time and rate of application of PBZ resulted in two significant trends of variations (increasing and decreasing) on fruit yields of tomato. Hence, it could be possible to propose that more assimilate reallocation to the fruits are significant advantage of PBZ treatments contributing to the improvement of seedling quality at planting for increased seedling survival rate, better stress protection, early and more fruit production.

Abstract:

The salinity tolerances of 21 accessions belonging to four wild tomato species [Lycopersicon pimpinellifolium (Jusl.) Mill., L. peruvianum (Corr.) D'Arcy, L. hirsutum (L.) Mill., and L. pennellii Humb. Bonpl.) were evaluated using their vegetative yield-salinity response curves at the adult stage, determined by a piecewise-linear response model. The slope (yield decrease per unit salinity increase), salinity response threshold, maximum electrical conductivity without yield reduction (ECo), and salinity level for which yield would be zero (ECo) were determined by a nonlinear least-squares inversion method from curves based on the response of leaf and stem dry weights to substrate EC. The genotype PE-2 (L. pimpinellifolium) had the highest salt tolerance, followed by PE-45 (L. pennellii), PE-34, PE-43 (L. hirsutum), and PE-16 (L. peruvianum). The model also was tested replacing substrate salinity levels with leaf Cl- or Na+ concentrations. Concentrations of both ions for which vegetative yields were zero (Clo and Nao) were determined from the response curves. In general, the most tolerant genotypes were those with the highest Clo and Nao values, suggesting that the dominant salt-tolerance mechanism is ion accumulation, but there were cases in which salt tolerance was not related to Clo and Nao.

Abstract:

Several studies were conducted to determine the effect of using tomato (Lycopersicon esculentum Mill.) plant skeletons as a support for trellised cucumbers (Cucumis sativus L.) double-cropped with tomatoes. In addition, the effect of mulch color, drip irrigation, and root-knot nematodes on subsequent cucumber yield also were examined. The presence of tomato skeletons significantly reduced the total yield (U.S. Fancy, no. 1, and no. 2), but not the premium (U.S. Fancy, no. 1) yield of cucumbers. Black polyethylene mulch used for the previous tomato crop had no undesirable effect on cucumber yield compared to the white mulch. Drip irrigated cucumber using same tomato irrigation lines significantly increased cucumber yield compared to nonirrigated cucumber. Cucumbers planted after nematode resistant tomatoes produced significantly higher yields than cucumber planted after nematode-susceptible tomatoes.

Abstract:

The relative importance of insects, weeds and diseases to yield losses in processing tomato (Lycopersicon esculentum Mill.) and cabbage (Brassica oleracea L. var. capitata L.) was measured by comparing yields in the presence and absence of appropriate control programs. In the absence of any pest control, average crop losses exceeded 80% in both crops. Average yield losses due to weeds alone approached 80% in processing tomato and 60% in cabbage. Insects alone did not significantly reduce yield of processing tomato in either year. In the absence of insect control, significant yield loss in cabbage approached 50% in only one year. When diseases were not controlled, yield of processing tomato declined significantly by nearly 30% in one trial. Failure to control disease had no significant impact on cabbage yield in this study. Monetary losses and costs of each management program were calculated. Key words: Tomato, cabbage, yield loss, insects, weeds, diseases

Abstract:

The Tully Sugar Mill has collected information about sugarcane supplied for crushing from every block in the mill district from 1970 to 1999. Data from 1988 to 1999 were analysed to understand the extent of the variation in cane yield per hectare and commercial cane sugar in the Tully mill area. The key factors influencing the variation in cane yield and commercial cane sugar in this commercial environment were identified and the variance components computed using a restricted maximum likelihood methodology. Cane yield was predominantly influenced by the year in which it was harvested, the month when the crop was ratooned (month of harvest in the previous year) and the farm of origin. These variables were relatively more important than variety, age of crop or crop class (plant crop, first ratoon through to fourth or older ratoons) and fallowing practice (fallow or ploughout-replant). The month-of-ratooning effect was relatively stable from year-to-year. Commercial cane sugar was influenced by the year of harvest, the month of harvest and their interaction, in that the influence of the month of harvest varied from year to year. Variety and farm differences were also significant but accounted for a much lower portion of the variation in commercial cane sugar. An empirical model was constructed from the key factors that influenced commercial cane sugar and cane yield to quantify their combined influence on sugar yield (t/ha). This may be used to assist mill personnel to predict their activities more accurately, for example to calculate the impact of a late finish to the current harvest season on the following year's crop.

Abstract:

The problem faced by the palm oil industry today is the instability of the Crude Palm Oil (CPO) yield. The condition of Fresh Fruit Bunches (FFB) starting from the time of harvesting to transporting to the factory, including during stockpiling at the palm oil mill, is an influential factor affecting the yield of CPO. This study aimed to find the factors causing instability of CPO yield in the palm oil industry. I-MR control maps and fishbone diagrams were used to analyze the factors that cause low CPO yields. From the data analysis for three years, the evidence of CPO yield was not statistically controlled. The causative factor of CPO yield instability included the quality of raw materials, production equipment, character of workers, and environmental conditions, with the dominating factor was the low quality of raw materials.

Abstract:

Five rocket (Eruca sativa (L.) Mill.) varieties and accessions were cultivated under field conditions in the Czech Republic (Central Europe) and subsequently studied for variation in morphology and yield. Two cultivation techniques (treatments) were tested during the growing seasons in 2010 and 2011: directly sown seeds in the field and plantlets cultivated in a glasshouse and later transplanted to the field. There were analysed four morphological parameters of the leaf rosette (leaf shape in outline, leaf margin, leaf apex and leaf colour), marketable yield, nonmarketable parts, and rosette radius. Plants from plantlets transplanted to the field in spring terms (April) yielded a substantially higher marketable yield and had a higher rosette radius in contrast to plants from directly sown seeds. Conversely, for the summer terms (late August, September) the direct sowing technique produced higher marketable yield in comparison with plantlets treatment. Plants cultivated from directly sowed seeds reached a marketable yield on average from 15 to 60 g per plant while transplanted plants produced on average from 10 to 49 g per plant. It is evident that cultivation of rocket under field conditions of the Czech Republic is possible and provides, when using the appropriate sowing term, more or less stable yields of marketable parts. Details on variation in yield parameters of individual varieties and accessions are presented.

Abstract:

The effect of six equidistant spacings (23, 30, 38, 45, 53 and 60 cm, corresponding to 113 000, 74 000, 53 000, 40 000, 31 000 and 25 000 plants ha−1, respectively) on fruit yield of four-row plantings of greenhouse tomato (Lycopersicon esculentum Mill. ’Jumbo’ and ’Ohio CR-6’) was studied over two spring and two fall seasons. Fruit was harvested and recorded separately from inside (shaded) and outside (exposed) plants of the four-row plantings. The total and marketable yield (g plant−1) of both inside and outside plants of both cultivars and in both seasons declined linearly with successive decreases in plant spacing. The rate of yield reduction of both cultivars was steeper in the spring, compared to the fall season. Also, the rate of yield reduction in the spring was steeper on inside compared to outside plants; but, in the fall, yield was similar for inside and outside plants. The response of the total and marketable yield (g m−2) of both inside and outside plants of both cultivars and in both seasons to decreasing plant spacing was described by a first or second degree polynomial. In the fall, the total and marketable yield of all plants increased (mostly) linearly with decreasing plant spacing; but, in the spring, yields were highest at intermediate spacings and declined with closer and wider spacings. We conclude that there is a greater potential for marketable yield increases, with any increase in plant density from a normal of 25 000 plants ha−1 to a maximum of 74 000 or 113 000 plants ha−1 for the cvs. Ohio CR-6 and Jumbo, respectively, in a fall greenhouse tomato crop than in a spring crop. However, with closer planting, a reduction in fruit size must be anticipated in both seasons.Key words: Lycopersicon esculentum Mill., plant spacing, greenhouse tomato

Abstract:

Introduction of the eight-roller mill into the wheat flour milling process significantly reduces the investment costs and overall energy requirements compared to the conventional milling system. However, the conditions for controlled milling are less favorable and could result in deterioration of flour yield and quality. Paper compares milling results obtained using a conventional process and process with an eight-roller mill employed on the tail-end passages of the reduction system. At the same roll gap and under the same sieving conditions, the flour release was lower in the process with the eight-roller mill compared to the conventional milling system. By decreasing the roll gap and increasing the upper size limit (granulation) of flour in the process with the eight-roller mill it is possible to increase flour yield and decrease milling energy consumption per unit mass of flour produced. This can be achieved without deterioration of flour quality as determined by ash content.

Abstract:

`Agriset', `All Star', and `Colonial' tomato (Lycopersicon esculentum Mill.) transplants set to a depth of the first true leaf and `Cobia' transplants set to a depth of the cotyledon leaves yielded more fruit at first harvest than plants set to the top of the rootball (root–shoot interface). The increase in fruit count was predominantly in the extra-large category. More red fruit at first harvest suggested that deeper planting hastens tomato maturity. The impact of planting depth diminished with successive harvests, indicating the response to be primarily a first-harvest phenomenon in tomato.

Abstract:

Ten cultivars of processing tomatoes (Lycopersicon esculentum Mill.) grown in bare soil or on black polyethylene and hairy vetch (Vicia villosa Roth.) mulches were evaluated for yield, fruit processing quality, and leaf necrosis. Yields were higher, fruit was heavier, and leaf necrosis less in hairy vetch than in bare soil or black polyethylene mulch. With the exception of pH, yield and fruit quality component responses to mulch treatments were not cultivar-dependent. Fruit pH, soluble solids concentration, and color equaled values obtained using bare soil production practices. Percent solids was highest with black polyethylene and lowest in hairy vetch. The hairy vetch mulch delayed fruit maturity compared to the bare soil and black polyethylene. The hairy vetch cultural system has the potential to increase yield of processing tomatoes.

Abstract:

Researchers have been attempting to improve the yield of bleachable-grade kraft pulp for several decades. Wood is typically one of the major costs associated with kraft pulping. Therefore, it is typically assumed that improving pulp yield or conversely, reducing the amount of wood required to make a specific mass of pulp, is a cost-effective, lucrative endeavor. Although this may be true, it is important to understand the impact of increasing pulp yield on the interconnected processes within an integrated pulp and paper mill and to fully evaluate the cost implications on these processes. The current work employed several sets of laboratory pulping conditions and a WinGEMS model of a pulp mill, fully integrated with chemical recovery, power, and recausticization, and pulp drying islands to determine where the largest cost impact associated with improved pulp yield may be experienced.

Abstract:

Lavandula angustifolia was watered with either deionized tap water treated with low-temperature, low-pressure glow plasma of low frequency in the air (LPGPA), under oxygen-free nitrogen (LPGPN), methane (LPGPM), carbon dioxide (LPGPC) or molecular oxygen (LPGPO). The crop yields were slightly dependent on the type of water used for watering. Notably, only plants watered with LPGPN showed a slightly higher crop yield. The plants also contained a higher level of protein and bioaccumulated magnesium. The type of water had a considerable and specific effect on the yield of isolated essential oils and their composition. The yield of essential oil decreased in the following order LPGPA = LPGPN (0.4 g/100 g dry mass) > LPGPC = LPGPO (0.3 g/100 g dry mass) > LPGPM = non-treated water (0.2 g/100 g dry mass). The composition of the isolated essential oils varied depending on the type of water used for watering, which influences their role as a fragrant component of cosmetics, and in herbal therapy and aromatherapy.

Genotypic variability, heritability and genetic advance for yield and yield contributing characters were studied on 55 tomato genotypes. Data were recorded on number of primary branches per plant, days to first flowering, plant height, number of bunches per plant, number of fruits per plant, individual fruit weight, number of seeds per fruit, dry matter content of fruits, pH level of fruit juice and yield per plant. Very little differences were observed between genotypic coefficient of variation and phenotypic coefficient of variation for all the characters except dry matter content and yield per plant indicating that they were less influenced to environmental factors for their phenotypic expression. High heritability estimates coupled with high genetic advance in percentage of mean were obtained for number of primary branches per plant, number of days to first flowering, plant height, number of bunches per plant, number of fruits per plant, individual fruit weight and number of seeds per fruit indicating wide scope for improvement through selection of these traits.DOI: http://dx.doi.org/10.3329/pa.v19i1.16982 Progress.

Abstract:

Celeriac (Apium graveolens L., Apiaceae), originating from the Mediterranean basin, is a two-yearold species grown worldwide. The article presents the content of chlorophylls a and b, β-carotene and anthocyanin in various celery root varieties, and an assessment of their resistance to septoriosis and the yield of root crops. The studies were carried out on the basis of the All-Russian Scientific Research Institute of Vegetable Growing, a branch of the Federal Scientific Vegetable Center (Moscow Region, Ramensky District) in 2014-2016. The total content of anthocyanins in the leaves in varieties with anthocyanin coloring on the leaf stem is on average 1.32 mg / 100 g, in the varieties with a green stem, 0.90 mg / 100 g, β-carotene – 1.82 and 1.67 mg / 100 g, chlorophyll a – 86.5 and 81.4 mg / 100 g, chlorophyll b – 43.1 and 44.9 mg / 100 g wet weight, respectively. Linear correlation analysis allowed to establish a reliable (at 5% significance level) positive relationship between the yield of root crops and the total content of anthocyanins in celery leaves (r = 0.53), the total content of anthocyanins and chlorophyll a in leaves (r = 0.55), a negative relationship between the degree of development septoria and root mass (r = -0.62), as well as the yield of root crops (r = -0.71), between the chlorophyll a content in the leaves and the degree of septoria development (r = -0.54). The revealed variability in chlorophyll, β-carotene, the total content of anthocyanins reflects genetic heterogeneity among the studied celery varieties and plant responses to the environment. For breeding for resistance to septoria and crop yields of root crops, varieties of celeriac Kornevoy Gribovskiy, Maxim, Kupidon were selected.

Abstract:

ABSTRACT We compared and statistically evaluated the effectiveness of nine DNA extraction procedures by using frozen and dried samples of two silt loam soils and a silt loam wetland sediment with different organic matter contents. The effects of different chemical extractants (sodium dodecyl sulfate [SDS], chloroform, phenol, Chelex 100, and guanadinium isothiocyanate), different physical disruption methods (bead mill homogenization and freeze-thaw lysis), and lysozyme digestion were evaluated based on the yield and molecular size of the recovered DNA. Pairwise comparisons of the nine extraction procedures revealed that bead mill homogenization with SDS combined with either chloroform or phenol optimized both the amount of DNA extracted and the molecular size of the DNA (maximum size, 16 to 20 kb). Neither lysozyme digestion before SDS treatment nor guanidine isothiocyanate treatment nor addition of Chelex 100 resin improved the DNA yields. Bead mill homogenization in a lysis mixture containing chloroform, SDS, NaCl, and phosphate-Tris buffer (pH 8) was found to be the best physical lysis technique when DNA yield and cell lysis efficiency were used as criteria. The bead mill homogenization conditions were also optimized for speed and duration with two different homogenizers. Recovery of high-molecular-weight DNA was greatest when we used lower speeds and shorter times (30 to 120 s). We evaluated four different DNA purification methods (silica-based DNA binding, agarose gel electrophoresis, ammonium acetate precipitation, and Sephadex G-200 gel filtration) for DNA recovery and removal of PCR inhibitors from crude extracts. Sephadex G-200 spin column purification was found to be the best method for removing PCR-inhibiting substances while minimizing DNA loss during purification. Our results indicate that for these types of samples, optimum DNA recovery requires brief, low-speed bead mill homogenization in the presence of a phosphate-buffered SDS-chloroform mixture, followed by Sephadex G-200 column purification.
