Linseed is an important industrial crop cultivated for its edible seeds and fiber linen. Organic fertilizers have beneficial effects on soil properties and quality of crops. Therefore, we conducted two field experiments during 2018–2019 and 2019–2020 to determine the effect of organic fertilizers on soil fertility, yield and fiber quality of linseed varieties Roshni, BL1 and Chandni under low soil moisture conditions. We prepared organic fertilizers from seed cake of Eruca sativa, leaves of Moringa oleifera and chicken peat in various combinations by composting method. The various formulations of organic fertilizers included OF1(1 kg seed cake of Eruca sativa), OF2 (1 kg seed cake of Eruca sativa + 1 kg chicken peat), OF3 (1 kg seed cake of Eruca sativa + 0.5 kg chicken peat + 0.25 kg Moringa oliefera leaves) and OF4 (1 kg seed cake of Eruca sativa + 0.250 kg chicken peat + 0.5 kg Moringa oliefera leaves). Compositional analysis of organic fertilizers indicated that OF3 and OF4 had higher and may potentially sufficient quantities of NPK and organic matter. Both of these fertilizers significantly improved soil total N, available P, K, Zn and Fe contents. Growth response of linseed varieties to organic fertilizers was evaluated under water deficit stress (40% field capacity of soil) at tillering stage for one month. Water stress had significantly adverse effects on plant height, production of tillers per plant, leaf relative water content (LRWC), number of capsules per plant, thousand seed weight, total seed yield, straw yield, fiber length and fiber weight of linseed varieties. However, the application of OF3 and OF4 significantly enhanced plant height, tillers production, LRWC, seed yield, straw yield, fiber length and fiber weight under water deficit stress. Water deficit stress also resulted in a significant increase in the content of phenolics of both the leaves and roots. For each measured quality parameter of linseed varieties, organic fertilizer treatments resulted in higher values than untreated and irrigated control. We concluded that organic fertilizers particularly OF3 and OF4 significantly improved soil fertility and minimized negative effect of water deficit stress on plant height, tillers production, LRWC, seed yield, straw yield, fiber length and fiber weight of linseed varieties.

Safflower (<em>Carthamus tinctorius</em> L.) is an oilseed crop adapted to arid and semiarid regions. In this study, an experiment was performed to evaluate the effects of water deficiency on plant height, 1,000-grain weight, seed yield, harvest index, relative water content (RWC), oil yield, and oil content in 15 safflower genotypes. A split-plot randomized complete blocks design was arranged with three replications. Safflower plants were grown under normal irrigation and water deficit conditions in Sarvestan, Fars Province, Iran during 2016 and 2017 growing seasons. Combined analysis results indicated that water deficit stress had negative effects on all measured indices. Average seed yield declined by 65.91% (2,337.91 to 796.79 kg ha<sup>−1</sup>) due to water deficit stress. Genotype also had a significant effect on evaluated indices, and the interaction between genotype and irrigation significantly influenced all indices except plant height. Under both conditions, highest RWC, seed yield, and oil yield were observed in Dincer and PI-537598 genotypes. Maximum plant height and 1,000-seed weight in both irrigation conditions were observed in the Dincer genotype. In the normal irrigation condition, maximum harvest index and oil content were observed in the CW-74 genotype. Thus, Dincer and PI-537598 were classified as the best genotypes (based on seed yield, RWC, and oil yield) under both normal irrigation and water deficit stress conditions.

To investigate the effects of sowing dates and late season water deficit stress on quantitative and qualitative traits of different canola cultivars, a 2-year field experiment was carried out in the 2014–2015 and 2015–2016 growing seasons. The experimental factors consisted of sowing date at two levels (7th and 27th October), irrigation at two levels (full irrigation and irrigation termination at silique formation stage) and four German canola cultivars including Trapper, Makro, Smilla, and Agamax. The results indicated that the main effects of sowing date, irrigation, and cultivar were significant on all studied characteristics except for harvest index. The interaction between sowing date and irrigation was also statistically significant on silique number per plant, oil percentage, linolenic acid, and erucic acid percentage. The results demonstrated that seed yield and its components oil percentage and oil yield, as well as oleic and linoleic acid percentage, decreased when sowing date was delayed until 27th October. Due to irrigation termination, all the studied traits decreased except for linolenic and erucic acid. Seed yield also decreased. The results suggest that to improve seed and oil yield, canola should be sown on 7th October and fully irrigated until physiological maturity stage in the study area.

Sowing depth and density are factors which affect development and yielding due to their influence on plants’ competition for water, light and nutrients. The aim of the present research was to evaluate the effect of sowing depth (5 and 8 cm) and density (45, 60, 75 seeds m2) on the development and yield of two morphotypes of faba bean. Higher plants were found at 8 cm sowing depth in 2011 and 2013, in turn, plant density before harvest, at 5 cm in 2011 and 8 cm in 2013. The greatest seed yield was observed while sowing shallower in 2011 (4.50 t ha−1) and 2012 (6.62 t ha−1), and deeper in 2013 (3.53 t ha−1). Cultivar played in important role in shaping plant height and seed yield in all years of the experiment, as well as in straw yield in 2012. Bobas characterized by the greatest seed productivity in all years of experiment compared to Granit, as well as quantity of straw yield in 2011 and 2012 (3.51 and 4.88 t ha−1, respectively) and therefore can be recommended for cultivation. Taking into account plant density before harvest in 2011–2013 as well as straw yield in 2011 and 2013, the most favorable sowing density is 75 seeds per m2.

We studied the fiber flax varieties bred in the Tomsk region in 2017–2019 in the subtaiga zone of the Omsk region on the experimental field of the Northern Agriculture Department of the Omsk Agricultural Scientific Center. We provide the material for 7 varieties. The soil of the experimental plot is gray wooded podzolic, medium, loamy with a humus content of 3–4 %. The predecessor is spring wheat after fallow. The research results showed that the weather conditions significantly affected the growth, development, and formation of the yield. In 2017, cold and wet weather generally affected the yield and quality of fiber flax in comparison to 2018-2019. As a result of the research, we established that for 3 years the best varieties were TOST 5 and Tomich. The variety TOST 5 gave a straw yield of 4.70 t/ha with number 1.9, an estimated fiber yield of 1.31 t/ha and a seed yield of 0.80 t/ha with the growth season of 61 days. The variety Tomich was characterized by the high quality of straw with number 2.1 with a short growth season (48 days), it had a straw yield of 4.0t/ha, a fiber yield of 1.18 t/ha and a seed yield of 0.70 t/ha. Therefore, the combination of varieties of different ripening duration will optimize the harvesting timing, raise the flax straw, and get a high yield of quality products.

Linum album (Ky. ex Boiss.) is an important medicinal plant that produces compounds such as the well-known anticancer lignan podophyllotoxin and fatty acids. Despite its high medicinal value, it has not yet been studied in detail under agricultural conditions. This study was conducted to evaluate the morphological, phenological, and physiological responses of six L. album accessions under different levels of water deficit treatments (100%, 75%, 50%, and 25% available water) in pot conditions. Based on the results, some of the morphological characteristics of the response to water deficit were established. Accessions UTLA7, UTLA9, and UTLA10 showed a higher seed yield and dry weight of the vegetative part. There was a substantial difference in the occurrence of phenological stages in the accessions. The maturation process was accelerated in plants under stress conditions, and accession UTLA9 completed its complete growth cycle faster than the other accessions. The physiological responses of the different accessions did not show the same pattern on the basis of the characteristics studied, and significant differences were observed depending on the trait and accession. Among the most important results of this study was the diversity of responses in different accessions. Based on these results, it is recommended that morphological features (such as seed yield per plant, plant height, number of inflorescences per plant, shoot and root dry weight) be used to select tolerant accessions for the desired product.

A field experiment was conducted during rabi season 2018-19 to study the response of 23 cowpea genotypes grown under residual moisture condition in rice-fallow situation of Goa state. Analysis of variance revealed significant differences among the genotypes for all the eleven characters, justifying the selection of genotypes for the study. The estimate of Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV) were high (>20%) for seed yield, straw yield, pods per plant and 100 seed weight. Heritability and genetic advance as per cent mean estimates were high for most of the characters except for days to 50 per cent flowering, days to maturity and plant height. Characters plant height, pods per plant, straw yield and harvest index showed positive and significant association with seed yield. Path analysis based on seed yield, as a dependent variable, revealed that straw yield and harvest index had the highest positive direct effect on seed yield. Therefore, maximum importance should be given to these traits during the selection for achieving the higher seed yield under rice-fallow situation. Three promising genotypes identified from this study viz., PCP-1131, SKAU-C- 407 and RC 101 would serve as dual-purpose cowpea under rice-fallow areas due to their high seed yield and straw yield

The objective of this study was to evaluate the physiological performance of wheat seeds coated with micronutrients. The treatments were combinations of two products based on micronutrients, product "A": 780.0 g.L-1 of zinc and product "B": 182.4, 7.6 and 45.6 g.L-1 of zinc, boron and molybdenum, respectively, with five dosages of the products: 0, 1, 2, 3 and 4 mL. kg-1 seed, totaling 10 treatments with four replications. Physiological quality of the treated seed was evaluated from germination and vigor tests and the early plant growth from determinations of shoot dry weight, plant height and leaf area at 10, 20 and 30 days after emergence (DAE), as well as the rate of crop growth, relative and net assimilation. Seed yield and physiological quality were determined after harvest. It was concluded that coating wheat seeds with the product "A" , based on zinc and "B", consisting of zinc, boron and molybdenum, respectively, up to a dosage of 4 mL.kg-1 seed, did not adversely affect the physiological quality of the treated seeds or those produced. Both products tested resulted in increases in leaf area, plant height and shoot dry weight up to 30 DAE, as well as a higher seed yield.

Two large-seeded buckwheat (Fagopyrum esculentum Moench.) cultivars, Mancan and Manor, and semi-dwarf lines, were grown at Morden and Portage la Prairie in the years 1979–1982 at seeding rates of 15, 30, 45 and 60 kg/ha. There was no consistent effect of seeding rate on plant height, seed weight (g/1000 seeds) or seed density. In six of the eight location-years there was no interaction of genotype × seeding rate for seed yield, indicating that, generally, the cultivars and lines reacted similarly to differences in seeding rate. It was concluded that a seeding rate of from 30 to 45 kg/ha would ensure optimum yield in most years.Key words: Buckwheat, Fagopyrum esculentum Moench., seeding rates

Varietal Differences

Feed supply in terms of quality and quantity plays an important role in livestock production and productivity. Here we report on varietal differences in yield and nutritional quality among 9 alfalfa accessions over 7 harvests following planting in Ethiopia. Experimental design was a randomized complete block with 3 replications at Chano Mille, Southern Ethiopia on a sandy loam soil where mean annual rainfall is 544 mm. Days to harvesting, plant height, dry matter yield, seed yield and the concentrations of the nutritional quality parameters crude protein (CP), neutral detergent fiber, acid detergent fiber, acid detergent lignin, hemicellulose and cellulose plus in vitro dry matter digestibility (IVDMD) and relative feed value (RFV) were assessed to rank the accessions. There were significant (P<0.001) differences between accessions and harvests in plant height, dry matter yield and seed yield. Accession ILRI_7323A performed best in all agro-morphological aspects. All accessions, except 1, produced forage with CP in excess of 30% and IVDMD greater than 80% with RFV greater than 150 at 50% flowering, indicating the high quality of forage produced. Further studies to assess the longevity of stands of the various accessions seem warranted along with studies in higher rainfall environments or under irrigation.
