A pot experiment was conducted to evaluate the response of two chickpea varieties to water stress at the College of Agriculture campus, Hawassa University under greenhouse from January to June 2017. Three water stress levels i.e. without stress (control), vegetative water stress and seed filling water stress were assigned as main plot, chickpea varieties Habru (Kabuli type) and Mastewal (Desi type). The treatments were laid in split plot design with four replications. The results showed that water stress significantly affected all parameters studied in this experiment. The seed filling water stress resulted greater reductions in the value of all tested parameters studied compared to optimum watering and vegetative stress except number of primary branches and harvesting index, which were significantly lower under vegetative water stress. As well, the two varieties significantly differed for all observed parameters except number of nodules per plant and nodule dry weight. Days to flowering, pod maturity, number of pods per plant, number of seeds per pod and harvest index were significantly higher for Mastewal variety while, plant height, number of primary branches, number of secondary branches, dry biomass, seed yield per plant, hundred seed weight and root dry weight were greater for Habru variety. Days to flowering, plant height, seed yield per plant, hundred seed weight, number of pods per plant and harvest index were significantly affected (p<0.05) due to all two way interactions. Water management schemes that ensure to avoid especially terminal water stress could help to maintain chickpea production, which is usually grown with residual moisture by the majority of Ethiopian farmers. Given the fact that the results are obtained from a pot experiment there is a need to substantiate the findings with field experiments conducted under contrasting moisture environments. Int. J.

The comparative effect of 0, 0.2, 0.4, 0.6 and 0.8% Zn levels of zinc chelate (Zn-EDTA; 8% Zn) and zinc sulfate (23% Zn) applied as foliar sprays for assuaging zinc deficiency of chickpea cv. Gökçe was evaluated under field condition. The sprays were applied on the plants before blooming stage during 2012 and 2013 growing seasons and seed yield, yield components like plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and mineral concentrations (nitrogen, phosphorus, zinc and iron) in seeds were investigated. Plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and seed yield were investigated. The results showed that increased zinc doses caused an increase in Zn content of seed, while seed yield was not affected similarly. In general, plant height, pod number and seed number per plant increased by the application of zinc. Lower dose of Zn-EDTA and higher dose of ZnSO<sub>4</sub> gave higher yield components. Seed weight, harvest index and seed yield were not significantly influenced by Zn sources and doses; however, mineral concentration of seeds enhanced when Zn doses were increased. It was concluded that foliar application of zinc resulted in an increase in seed mineral contents rather than seed yield of chickpea. The dose of 0.6% with Zn-EDTA was the optimum combination for Zn enrichment in seed of chickpea.

Abstract A research was conducted to evaluate the impact of various nitrogen and phosphorus levels along with beneficial microbes to enhance canola productivity. The research was carried out at Agronomy Research Farm, The University of Agriculture Peshawar in winter 2016-2017. The experiment was conducted in randomized complete block factorial design. The study was comprised of three factors including nitrogen (60, 120 and 180 kg ha-1), phosphorous (70, 100 and 130 kg ha-1) and beneficial microbes (with and without BM). A control treatment with no N, P and BM was also kept for comparison. Application of beneficial microbes significantly increased pods plant, seed pod, seed filling duration, 1000 seed weight, biological yield and seed yield as compared to control plots. Nitrogen applied at the rate of 180 kg ha-1 increased pods plant-1, seed pod, seed filling duration, seed weight, biological yield and seed yield. Maximum pods plant-1, seed pod, early seed filling, heavier seed weight, biological yield, seed yield, and harvest index were observed in plots treated with 130 kg.ha-1 phosphorous. As comparison, the combine treated plots have more pods plant-1, seeds pod-1, seed filling duration, heaviest seeds, biological yield, seed yield and harvest index as compared to control plots. It is concluded that application of beneficial microbes with N and P at the rate of 180 kg ha-1 and 130 kg ha-1, respectively, increased yield and its attributes for canola.

The present study was conducted at the Research farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, during March to June 2014 to examine the effect of Phosphorus on the growth and yield of Sesame. BARI Til-3 variety was used for the study. This experiment was consisted of single factor eg. phosphorus. There were three levels of phosphorus viz. (i) P0 (0 % P), (ii) P1 (20 % P) and (iii) P2 (30 % P) and the experiment was laid out in a Randomized Complete Block Design (RCBD) with six replications. Different levels of phosphorus showed significant effect on growth and yield of sesame. Individually phosphorus had significant effect on highest plant height, number of leaves plant-1, number of primary branches plant-1, number of secondary branches plant-1, number of capsule plant-1, number of seeds capsule-1, 1000 seed weight, seed yield and harvest index. The highest plant height of sesame (136.30 cm), the highest no leaves plant-1 of sesame (34.44), number of primary branches plant-1 (5.56), number of secondary branches plant-1 (7.61), number of capsule plant-1 (25.87), number of seed capsule-1 (70.47),1000 seed weight (3.54), Seed yield (1581.00 kg ha-1), Stover yield (3034.42 kg ha-1), biological yield (4615.76), harvest index (34.11%), oil content (43.92%) was recorded from P1. Again, the highest days to first flowering of sesame (31.67) was recorded from P1 (20 % P) but the highest days to maturity was (85.67) recorded from P2 (30% P). Application of P at different percentage is causing effect in growth and yield of sesame. Res. Agric., Livest. Fish.6(2): 245-251, August 2019

The effects of seeding date and seeding rate on the agronomic characteristics of five genotypes of Brassica napus L. were studied for 2 yr at two locations in western Canada. Delayed seeding resulted in a significant increase in vegetative and total yield but a significant decrease in seed yield, harvest index, plant density, racemes per plant and racemes per unit area. Seeding date had no significant effect on seed yield per plant, 1000-seed weight and plant height. Increased seeding rate resulted in a significant increase in plant density, and racemes per unit area, but a significant decrease in harvest index, racemes per plant, seed yield per plant and plant height. Seeding rate had no significant effect on seed, vegetative or total yield and 1000-seed weight. There were significant differences due to genotypes for all variables except for total yield and racemes per unit area.

Forty genotypes of chickpea (Cicer arietinum L.) were studied in a field experiment conducted at the experimental field of BARI, Joydebpur, during the year 2004-2005. Significant genetic variations were observed among the genotypes for days to flower, plant height, number of branches per plant, number of pods per plant, 100-seed weight and seed yield per plant. The highest genotypic variability was observed in number of seeds per pod and seed yield, followed by number of pods per plant and branches per plant, whereas days to maturity showed the lowest genotypic co-efficient of variability. In all cases, phenotypic variances were higher than the genotypic ones. High heritability coupled with high genetic advance was observed for seed yield per plant, pods per plant, 100-seed weight and dry weight per plant, which indicates that selection could be effective for these traits. Considerable heritability was observed in pod length, seeds per pod and days to flowering. The results showed that seed yield per plant had positive and significant relation with branches per plant and pods per plant. Number of pods per plant were positively correlated with branches per plant but negatively correlated with plant height and days to first flowering. Weight of 100-seed had significant and positive correlation with days to first flowering, dry weight per plant and pod length but had negative correlation with pods per plant and seeds per pod. Days to first flowering, pod length, pods per plant, dry weight per plant had direct effect on yield. Therefore, days to first flowering, pods per plant, pod length, branches per plant and dry weight per plant are found the important characters which could be used in selection for yield.

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.

Background: Lentil is the major cultivated pulse crop in the state of West Bengal in terms of total area coverage under cultivation. Selection of high yielding and better quality genotype is the prime vital matter to increase productivity. Investigation and a better understanding of the variability existing in a population base of the crop are pivotal to crop improvement so that the plant breeders can exploit it. Methods: The current study has been carried out at the experimental farm of the University of Calcutta during 2016-2017 in a plot designed with the randomized block design. It was carried out to estimate the magnitude of genetic variability, heritability and genetic advance of fifty-four lentil germplasms. Result: Moderate to high heritability, GCV, PCV, GA and GA % of mean was obtained by days to1st flowering, days to 50% flowering, pods per plant and harvest index. The genotypic and phenotypic association of seed yield was significantly positive with traits like plant height, pods/plant, 100 seed weight and harvest index. Characters like days to 50% flowering, plant height, primary branches per plant, pods/plant, pod length, 100 seed weight and harvest index shows a positive direct effect on seed yield in path analysis suggesting select for such traits while exercising selection for seed yield per plant in lentil.

Genetics of agronomic traits in safflower was determined using 6×6 full diallel population. Data were recorded on days to flowering, days to maturity, plant height, primary branches per plant, head diameter, number of heads per plant, number of seeds per head, 1000-seed weight and seed yield per plant. Variance components showed that days to maturity and heads per plant were largely controlled by dominance gene effects, whereas 1000-seed weight, plant height and seeds per head were governed by additive type of gene action. The results also revealed both additive and non-additive types of gene actions for remaining traits. The significant mean squares of reciprocal crosses for days to flowering, head diameter, number of seeds per head, 1000-seed weight and seed yield per plant suggested that maternal inheritance also played an important role in the inheritance of these traits. Significant general combining ability for yield revealed that genetic improvement through accumulation of desirable alleles from parents in the target genotype using appropriate selection methods would be desirable in safflower.

The study of the effect of three well known mutagens, ethyl methane sulphonate (EMS), methyl methane sulphonate (MMS) and gamma rays (GR) on the yield contributing traits of the urdbean variety TPU-4 were carried out in the M3 generation. Effect of selected mutagenic treatments/doses of EMS (0.02, 0.03 and 0.04 M), MMS (0.0025, 0.05 and 0.01 M) and (GR) (30, 40 and 50 KR) on different yield contributing traits like plant height, plant spread, number of pods per plant, pod length, number of seeds per pod, seed yield per plant and 100 seed weight were analyzed in the M3 populations of the variety TPU-4. Seeds of M2 plants and control were harvested separately and sown to raise M3 population.. Genetic variabilty in the mutagen administered M3 progeny of the urdbean variety TPU-4 was analyzed by employing statistical methods. Data on mean values and shift in the mean of seven quantitative traits was evaluated on individual plant basis. The experimental findings revealed that concentrations / dose of the all these mutagens showed inhibitory effect on plant height, number of pods per plant, pod length and number of seeds per pod. Lower concentrations of mutagens exerted a promotory effect on plant spread, 100 seed weight and seed yield per plant while higher concentrations of these mutagens inhibited them to different extent.
