Field studies were conducted at three locations over three years with Linum usitatissimum L. to determine whether the solin cultivar Linola 947 and the traditional oilseed flax cultivars McGregor and Vimy, differed in seed yield, straw yield and harvest index response to N and P fertilizer and the phosphorus-solubilizing fungus, Penicillium bilaji, marketed as "Provide". While cultivars differed in seed yield, straw yield and harvest index, the relative performance of the cultivars varied with site and year and did not relate to whether the cultivar was solin or traditional oilseed flax. The degree and pattern of response of straw yield and harvest index to N and/or P fertilization varied with year and location. Where significant differences occurred due to P or Provide management, seed yield and harvest index were lower and straw yield higher with application of Provide than with application of P fertilizer, indicating that Provide was less effective than P in enhancing seed yield of flax. Solin did not generally differ from traditional oilseed flax in the response of seed yield, straw yield and harvest index to fertilizer applications. Response of seed and straw yield to N and response of harvest index to P each differed among cultivars in only one-site year, while an N-by-P-by-cultivar interaction occurred in only one site-year for seed and straw yield. Considering the limited occurrence of cultivar-by-fertilizer interactions, fertilizer recommendations produced for traditional flax cultivars should also be applicable to solin cultivars.

Important Trait

Background: Seed yield is a very important trait for selection but shows low heritability and hence is difficult to improve. Since the productivity of linseed (Linum usitatissimum L.) in India as well as Himachal Pradesh is low in comparison to other major linseed growing countries and states, improvement in cultivars for grain yield is a must. Therefore, the present study was aimed for studying the character associations in linseed genotypes for seed yield over locations. Method: The experiment was conducted during rabi 2019-2020. The experimental material for the present investigation comprised of 52 linseed genotypes grown over three locations in Himachal Pradesh i.e. Linseed Experimental Farm, CSK HPKV, Palampur (1290 m amsl), Shivalik Agricultural Research and Extension Centre, Kangra (700 m amsl) and Hill Agricultural Research and Extension Centre, Dhaulakuan (468 m amsl). Randomized block design with three replications was used. Phenotypic and genotypic correlation coefficients were worked out as per the procedure outlined by Burton and De Vane (1953) and Johnson et al. (1955). Direct and indirect effects of component traits on grain yield were worked out using correlation coefficient of various traits as suggested by Wright (1921) and elaborated by Dewey and Lu (1959). Result: Correlation studies indicated highly significant positive correlation for seed yield with 1000 seed weight (0.965**) followed by harvest index (0.801**), secondary branches (0.585**) and a significant correlation with biological yield (0.269**). Seed yield exhibited a non-significant positive correlation with seeds per capsule. However, a negative significant correlation was observed for seed yield with days to 50 per cent flowering and number of primary branches. The path coefficient analysis indicated that 1000 seed weight exhibited maximum positive direct effect with seed yield (0.741) while others had a low direct effect. The significant positive correlation of number of secondary branches and harvest index with seed yield was mainly due to indirect effect via 1000 seed weight indicating that 1000 seed weight is the most important trait for the improvement of grain yield in linseed as per the present study.

Four field experiments were conducted during 1988 to 1990 to evaluate the response to fertilizer P of six crisphead lettuce (Latuca sativa L.) cultivars grown on Histosols. There were season × cultivar interactions for total mass produced, marketable yield, and P uptake by lettuce. A significant yield response to fertilizer P was demonstrated during all four seasons. The performance of individual cultivars within a given season led to cultivar × P rate interactions for marketable yield. However, there were no significant P rate × cultivar interactions for total mass produced, P uptake, and marketable yield during the one season when growing conditions were near ideal. Calculated critical soil-test P values for both eastern and western lettuce types produced in Florida were all within error currently associated with P fertilizer recommendations for lettuce produced in Florida. Therefore, we conclude that no immediate change in P fertilizer recommendations is required for the new western-type lettuce cultivars produced on Histosols in Florida.

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

AbstractPresent study is performed to evaluate the effects of foliar application of salicylic acid, glycine betaine, ascorbic acid, nano-silica and nano titanium dioxide on yield and yield component of sunflower. Chlorophyll content, leaf length, leaf width, days to 50 % flowering, day to maturity, plant height, husk percentage, number of seeds per head, head number per plant, percentage of empty achenes, 1000-seed weight, kernel weight, grain length, straw yield, harvest index, grain yield and oil percent were measured. Results showed that the first two principal components accounted 49 % and 19 %, respectively of sums of squares of the TT interaction and were used to create a two-dimensional treatment by trait (TT) biplot. The vertex treatments in polygon of TT biplot were ascorbic acid, glycine betaine, nano-TiO2 and control which Nano-Ti2 treatment indicated high performance in chlorophyll content, day to maturity, number of seeds per head, head number per plant, kernel weight, grain length, straw yield, harvest index, grain yield and oil percent. The identification of ideal treatment, the treatment that is most favorable treatment among all treatments, showed that the nano-TiO2 might be used in selecting superior traits and it can be considered as the candidate treatment. Treatments suitable for obtaining of high seed yield were identified in the vector-view function of TT biplot and displayed nano-silica and nano titanium dioxide as the best treatments suitable for obtaining of high seed yield. In short, nano-fertilizer could increase crop yields and improve the fertilizer efficiency.

Field studies were conducted to evaluate the effect of the rate and timing of N application and the amount of seed-placed P on grain yield and protein content of winter wheat grown on zero-tilled and conventionally tilled land in Manitoba. Yield increased with increasing amounts of fall-applied N and P. Yield, as affected by time of N application, decreased in the order: spring, freezeup, seeding, and applied on snow in winter. Split application of N resulted in yields comparable to that obtained with N applied at seeding. Protein concentration in grain decreased when small amounts of N led to large increases in dry matter but increased when sufficient quantities of N fertilizer were added to meet the requirements for both yield and protein. The amount of fertilizer N recovered in the grain did not differ with time of application in 1979–1980. However, in 1980–1981, N recovery was consistently higher with spring applications of N than with applications at any other time. Differences between the two seasons reflected the higher moisture availability for crop growth in 1980–1981 as compared to 1979–1980.

Forty five linseed genotypes (local collection) were subjected to study the genetic variability at the Experimental Farm of the Department of Crop Improvement, CSK Himachal Pradesh KrishiVishvavidyalaya, Palampur, during rabi 2015-2016. Analysis of variance revealed that the differences among all the genotypes were significant for all the traits. Mean performance of genotype KLSA-15 for seed yield recorded highest contribution of 3.69 grams. The PCV values were greater than the GCV values for all the traits studied indicating that the apparent variation is not only due to genotypes but, also due to the influence of environment. The highest PCV (64.17) and GCV (64.09) were found for biological yield per plant. Higher estimates of PCV and GCV were obtained for primary branches per plant, secondary branches per plant, capsules per plant, biological yield per plant, harvest index (45.94 and 44.60) and seed yield per plant (52.39 and 50.94). All the characters studied in the present investigation expressed high heritability estimates ranging from 62.95 to 99.77 percent for technical height and biological yield per plant respectively. It was revealed that most of the traits under study showed low genetic advance, high heritability (94.23) and high genetic advance (31.06) was recorded for harvest index indicating predominance of additive gene action for this character. Simple selection based on phenotypic performance of this character would be more effective. The cluster analysis showed that the genotypes were placed into four clusters, showing inter-cluster divergence, which is important for future hybridization programme.

Flax (Linum usitatissimum L.) was grown in two growth chamber experiments on a total of 16 Black Chernozemic soils varying in content of Mg, Ca, P, and Zn. On three of the soils, dry matter yield of flax increased in response to application of P. Phosphorus availability was greater with broadcast than with banded fertilizer applications. Increased yield in response to Zn application was observed on one-half of the soils. Applications of P that increased P level in the tissue above 0.46% led to consistent but nonsignificant decreases in yield and reduced the level of Zn in the tissue. Zinc fertilization increased Zn and decreased P level in the tissue. Yield response to P application was not strongly related to soil chemical parameters measured, but increased as tissue P level decreased and tissue Zn level increased. High levels of soil Mg and soil pH and high tissue levels of Mg and P were the factors most closely associated with a yield response to Zn applied with P.

Methodology: Two field experiments were conducted on the Experimental Farm at El-Gemmeiza Research Station, Gharbia Governorate, Agricultural Research Center, Egypt, during two successive winter seasons of 2018-19 and 2019-20. Aims: To investigate the effect of three nitrogen fertilizer rates, i.e. 30, 50 and 70 kg N feddan-1 [one feddan (fed) = 4200 m2] and three plant densities, i.e. 1500, 2000 and 2500 seeds m-2 on flax (Linum usitatissimum L.) yield and its quality of three cultivars of flax, i.e. Sakha 3, Giza 11 and Giza 12. Results: Results in combined analysis of the two seasons showed that Sakha 3 cultivar significantly produced the maximum total plant height, technical stem length, upper branching zone length, No. of seeds capsule-1, total fiber percentage, fiber yield plant-1, fiber yield fed-1, fiber length and fiber fineness. Meanwhile, the highest No. of basal branches plant-1, straw yield plant-1, straw yield fed-1 and seed oil content were recorded with Giza 12 cultivar. While, Giza 11 cultivar gave the maximum stem diameter, No. of upper branches plant-1, No. of capsules plant-1, No. of seeds plant-1, seed index, seed yield plant-1, seed yield fed-1, harvest index, oil yield plant-1 and oil yield fed-1. Increasing nitrogen fertilizer rates from 30 up to 70 kg N fed-1 caused significant increases in almost straw, fiber, seed and oil yields and its related traits of flax, on the other hand, fiber fineness which significantly decreased with increasing nitrogen rates. Flax plants growing at 1500 seeds m-2 markedly gave the greatest No. of basal branches plant-1, stem diameter, straw yield plant-1, upper branching zone length, No. of upper branches plant-1, No. of capsules plant-1, No. of seeds plant-1, seed yield plant-1, harvest index, oil yield plant-1 and fiber yield plant-1. Meanwhile, the maximum total plant height, technical stem length, straw yield fed-1, seed yield fed-1, oil yield fed-1, total fiber percentage, fiber yield fed-1, fiber length and fiber fineness were obtained from flax planting at 2500 seeds m-2. The maximum fiber yield were recorded from the interactions among treatments Sakha 3 X 70 kg N fed-1, Sakha 3 X 2500 seeds m-2, 70 kg N fed-1 X 2500 seeds m-2 and Sakha 3 X 70 kg N fed-1 X 2500 seeds m-2. Meanwhile, the maximum seed and oil yields fed-1 were recorded from the interactions between treatments Giza 11 X 70 kg N fed-1, Giza 11 X 2500 seeds m-2, 70 kg N fed-1 X 2500 seeds m-2 and Giza 11 X 70 kg N fed-1 X 2500 seeds m-2. Generally, it could be concluded that Sakha 3 cultivar under soil fertilized by 70 kg N fed-1 with plant density of 2500 seeds m-2 to maximizing fiber yield fed-1, while Giza 11 cultivar with the same rates of nitrogen and plant density to maximizing seed and oil yields fed-1.

The experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka with the financial support of SAURES (Sher-e-Bangla Agricultural University Research System) to study the possibility of growing quinoa in Bangladesh with different sowing dates having two cultivars. The experiment comprised of two factors; Factor A: Cultivar (2) viz., Titicaca (C1) and Vikinga (C2) and Factor B: Sowing date (5) viz. November -10 (S1), December -10 (S2), January -10 (S3), February -10 (S4) and March -10(S5). The experiment was laid out in split-plot design with three replications. Results revealed that different growth parameters, yield attributes and yield were significantly varied with different sowing dates. At harvest, the tallest plant height (63.75 cm), highest seed yield (0.77 t ha-1) and straw yield (0.89 t ha-1) was found from Titicaca but the higher number of branches plant-1 (17.71) from Vikinga. The tallest plant height (62.54 cm), highest branch number plant-1 (22.82), longest inflorescence (29.62 cm), highest 1000-seed weight (2.56 g), seed yield (1.09 t ha-1), straw yield (1.25 t ha-1) and harvest index (46.58%) was exhibited by November -10 sowing. The interaction effect of Titicaca sown in November -10 (C1S1) resulted the highest plant height at harvest (72.83 cm), branches plant-1 (25.20), 1000-seed weight (2.58 g), seed yield (1.16 t ha-1) and straw yield (1.33 t ha-1) but the highest inflorescence length (31.46 cm) and harvest index (47.02%) from C2S2 (Vikinga sown in December – 10). From the above results it can be concluded that quinoa – as a new crop is suitable to cultivate in Rabi season of Bangladesh with a complete agronomic management package. Bangladesh Agron.
