An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from November 2007 to March 2008 to study the effect of sowing date and seed rate on the yield and yield components of two mustard varieties. The treatments included two varieties viz. BARI Sarisha-9 and BARI Sarisha-6; three sowing date viz. 10, 20 and 30 November, and three seed rates viz. 8, 10 and 12 kg seeds ha-1. The experiment was laid out in a split plot design with three replications. It was observed that the variety had significant influence on the yield and yield contributing characters except non-effective pods plant-1, non-effective seeds pod-1 and 1000-seed weight. Higher seed yield was obtained by the variety BARI Sarisha-9. The highest seed yield (1.53 t ha-1) was recorded in 10 November sowing and the lowest one was achieved in 30 November sowing. Seed rate had also significant effect on plant height, branches plant-1, pods plant-1, effective pods plant-1, pod length, no. of seeds pod-1 and seed yield. The seed rate 8 kg ha-1 produced the highest seed yield (1.49 t ha-1) and the lowest seed yield was produced by 12 kg seeds ha-1. Among the yield contributing characters only harvest index and non-effective pods plant-1 were significantly influenced by the interaction of variety and date of seeding as well as the interaction of variety and seed rate. The highest seed yield (1.63 t ha-1) was produced when BARI Sarisha-9 was sown on 10 November. In case of interaction between variety and seed rate, BARI Sarisha-9 with 10 kg seeds ha-1 produced the maximum seed yield. Results further showed that the interaction of 10 November sowing with 8 kg seeds ha-1 produced the highest seed yield (1.55 t ha-1).

A field experiment was carried out at University of Dhaka from March to July, 2011 to study the effect of time of sowing on the growth and yield of BARI mung-5. The treatments consisted of three dates of sowing viz. March 15, April 15 and May 15. The crop responded significantly to sowing time and 15 April sowing seeds produced plants having maximum plant height (68.4 cm), leaves/plant (29.33), total dry matter/plant (17.99), branches/plant (8.17), pods/plant (11.33), pod length (8.78 cm), seeds/pod (11.17), 1000 seed weight (46.52 g), seed yield/plant (5.33 g), yield/ha (1.77 t) and harvest index (29.58 %) at harvest. The seed yield decreased by 36.8 and 49.9% when seed sown early (15 March) or late (15 May) due to production of lower yield components.   DOI: http://dx.doi.org/10.3329/jbas.v36i2.12966   Journal of Bangladesh Academy of Sciences, Vol. 36, No. 2, 227-231, 2012

The experiment was carried out to study the effect of variety and level of phosphorus fertilizer on the yield and yield components of lentil at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during October 2009 to March 2010. Three lentil varieties viz. BINA masur 2, BINA masur 3 and BARI masur 4 and four levels of phosphorus viz. 0 kg P ha-1 (P0), 15 kg P ha-1 (P15), 30 kg P ha-1 (P30) and 45 kg P ha-1 (P45) were used in this experiment. Varieties showed significant influence on the all characters except plant height. The highest seed yield (1165 kg ha-1) was observed in BARI masur 4, and the lowest seed yield (1028 kg ha-1) was found in BINA masur 3. Phosphorus fertilizer had a significant effect on all the plant characters studied except 1000 seed weight. The highest seed yield (1222kg ha-1) was observed in P45 (45 kg P ha-1) treatment and the lowest seed yield (893 kg ha-1) was found in P0 treatment. In case of interaction, effect of cultivar and phosphorus fertilizer doses had a significant effect on all the plant characters studied except seeds pod-1 and 1000-seed weight. The highest seed yield (1317 kg ha-1) was obtained in V3 X P45 treatment, and the lowest seed yield (830 kg ha-1) was observed in V2 X P0 treatment combination. Among the varieties BINA masur 2 and BARI masur 4 were superior to BINA masur 3 in respect of yield performance with 30 kg P ha-1. BARI masur 4 fertilized with 30 kg P ha-1 produced the highest seed yield. Int. J. Agril. Res. Innov. & Tech. 3 (1): 78-82, June, 2013 DOI: http://dx.doi.org/10.3329/ijarit.v3i1.16097

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 This research aims to determine the relationship between yield and yield components of French bean using multivariate statistical techniques. The study was conducted at Horticulture Research Station, Dailekh, Nepal for consecutive three year of 2016-2018. In this study, six French bean genotypes were used. The following measurements and observations were made: germination (%), pod length (cm), pod diameter (mm), individual pod weight and number of seeds pod-1, number of dry pods plant-1, dry pod yield plant-1 and dry pod yield (t/ha), 100 seed weight (g) and seed yield (t/ha). Highly significant and positive correlation was recorded between seed yield and individual pod weight (r=0.659***), number of seed pod-1 (r=0.548**) and pod length (0.459*). Conversely, pod diameter showed a negative and non-significant (-0.025) correlation on seed yield. Based on simple regression analysis, linear regression of individual pod weight, number of seed pod-1 and pod length leads to an increase in the seed yield (t/ha) by 0.188, 0.285 and 0.103 units respectively. From the path coefficient analysis maximum positive direct effect on seed yield was recorded by number of seeds pod-1 (0.767) followed by 100 seed weight (0.530) and individual pod weight (0.429). Also, stepwise multiple linear regression analysis revealed that three traits including individual pod weight, 100 seed weight and number of dry pod plant-1 with R2 = 68.22% showed their overall contribution towards seed yield. The rest of the variance (R2 = 31.78%) was contributed by the variables that were not included in the study. Results concerning four statistical methods showed that individual pod weight appeared to be most effective contributor of seed yield followed by the number of seed pod-1, 100 seed weight, and pod length. Therefore, attention should be paid to these characters in any breeding program during the selection criteria for improving the seed yield.

Abstract In order to study the role of leaf position on yield and yield component of maize, this research was conducted based on randomized complete block design with three replicates at the research field of Urmia University, Urmia, Iran, in 2011. For determine the role of leaf position in maize yield, we used the leaf removing (clipping) treatments. Leaf clipping treatments contain ear leaf clipping, above ear leaf clipping, below ear leaf clipping and control (without leaf clipping) that imposed at one week after ear initiation. Leaf removing had a significant effect on all measured traits (number of seed per row, row number per ear, ear length, 1000 seed weight, seed yield, biological yield), except harvest index. Removing of above leaves decreased 6.68% the number of seeds on ear compare to control. The highest 1000 seed weight (274 g) was observed in plants without leaf clipping. Ear leaf clipping and below ear leaf defoliation ranked second for 1000 seed weight. Whereas plants without any leaf clipping had the utmost seed yield (8.77 t ha-1) but defoliating of leaf above ear lead to lower seed yield (6.77 t ha-1). Leaf removal above ear decreased 22.80% biological yield compared to control. The correlation analysis showed that all traits had positive correlation with seed yield. The most correlation was between ear length and number of row per ear (r=0.89**). Also, number of seed per row (r=0.71**), 1000 seed weight (r=0.67**), ear length (r=0.65**), biological yield and harvest index (r=0.59**) showed the most correlation with seed yield, respectively. Results revealed that the most reduction in all traits accrued in maize plants with above ear leaf clipping, this results indicated that the important roles of leaves position especially the role of above ear leaves in yield and yield components of maize.

The area coverage and productivity of linseed decreased from time to time; even there is no crop package and recommended row spacing and seed rate at regional level due to lack of attention by researchers and also by farmers. In Ethiopia, linseed has been cultivated for two primary purposes, seed and oil use. Its production in Ethiopia country is characterized by low input, low yield and poor product quality mainly due to attitude and poor management practices such as lack of proper weed management system, poor seed and field hygiene, poor seed bed preparation, inadequate plant nutrition, inappropriate seeding rate and spacing (mostly broad casting), improper threshing ground and improper cleaning. Field experiment was carried out to evaluate the effects of seed rate and row spacing on the yield and yield components of linseed, during 2017/2018 cropping season at Dabat district, North Western Ethiopia. KULUMSA1 (CHILALO) was used as test crop. Factorial combinations of three row spacing, (20, 25, and 30 cm) and three seed rates, (40, 45 and 50kgs) were laid out in RCBD with three replications.  Data regarding different parameters were recorded from days to sowing up to different stages. Statistical analysis of data showed that most of the parameters were affected by the main effects of Seed Rates and Row spacing. The main effect of seed rate was highly significant for days maturity, thousand seed weight and harvest index of linseed. More over it was significant for days to flower and number of capsule per plant, but it was not significant to plant height and bio mass yield. The main effect of row spacing was significant for days to maturity. The interaction of seed rate and row spacing was highly significance (p<0.05) for number of primarily branch per plant and seed yield. It was not significant on number of seeds per capsule, number of capsule per plant and thousand seed weight. The main finding of this research is highest seed yield (1771 kg ha-1 ) was obtained at 40kg ha-1 x 25 cm of row spacing while the lowest seed yield (752kg ha-1) was recorded at 50 kg ha-1 x 30 cm. 40kg ha-1 and 25cm is recommended to increase yield of linseed and its components. In conclusion the effect of seed rate and row spacing affects the important yield components of linseed.

An experiment was conducted at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University, and Mymensingh to study the effect of phosphorus and boron on the growth and yield of var. BARI Jharsheem-3 along with French bean during November 2017 to March 2018. The experiment was comprised of two factors involving number of levels viz. phosphorus had four levels  15, 20, 25 and 35 kg ha-1 and four levels of boron viz. 0, 0.5, 1.0 and  1.5 kg  ha-1. Triple super phosphate and Borax were used as source of phosphorus and boron, respectively. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The results exhibited that yield and its contributing characters were significantly influenced by the phosphorus and boron applications. The experimental findings revealed that highest  number of pods per  plant (4.95), pod length (13.06 cm), number of seeds per pod (4.34), and 1000-seed weight (427.99 g), seed yield (1.40 t ha-1), stover yield (1.76 t ha-1), biological yield (3.16 t ha-1) and harvest index (46%) were recorded under phosphorus level at 25 kg ha-1. The experimental findings also revealed that the highest number of pods per plant (4.91), pod length (14.45 cm), number of seeds  per pod (4.36), and 1000-seed weight (427.22 g), seed yield (1.39 t ha-1), stover yield (1.68 t ha-1), biological yield (3.07 t ha-1) and harvest index (45.27 %) were recorded  under boron level at 1.5 kg ha-1. In case of  interaction of phosphorus and boron, the highest number of pods  per plant (5.18),  pod length (14.35 cm), number of seeds pod-1 (4.84), and 1000-seed weight (427.19 g), seed yield (1.86 t ha-1), stover yield (2.05 t ha-1), biological yield (3.91 t ha-1) and harvest index (47.57 %) were recorded under P level at 25 kg  ha-1  and B level at1.5 kg ha-1. So it may be concluded that 25 kg P ha-1 and 1.5 kg B ha-1 could be applied to obtain higher yield of bean.

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.

A study was conducted at Bangladesh Agricultural University, Mymensingh during March-June, 2013 to evaluate the performance of mungbean varieties and to determine the optimum seed rate under strip tillage system. Three mungbean varieties (BARI Mung-6, Binamung-5 and Binamung-8) were tested against five seeding rates (20, 25, 30, 35 and 40 kg ha-1). The experiment was laid out in splitplot design with three replications. The study revealed that variety and seed rate had significant effect on plant population, pods plant-1, pod length, seeds pod-1, seed yield and stover yield of mungbean. The highest seed yield was obtained from Bina mung-5 at 35 kg seed ha-1 while the highest stover yield was obtained from 40 kg seed ha-1. For BARI Mung-6 and Binamung-8, 35 kg seed ha-1 also provided higher seed yield than other seeding rates. Nevertheless, the lowest seed and stover yields were obtained from Bina mung-8 with 20 kg seed ha-1. Therefore, the study concluded that machine seeding of mungbean at 35 kg seed ha-1 ensure optimum seed yield for tested varieties under strip tillage system and cultivation of Bina mung- 5 at 35 kg seed ha-1 can produce the maximum seed yield under this system.Bangladesh Agron.

SUMMARYTen selections from the cultivar China A, with widely different pod lengths, were compared in a single environment in Perth in 1983. Pod length was correlated positively with seed weight per pod but negatively with number of pods per plant. As a result, there was no significant relationship between pod length and seed yield, although the highest- and lowest-yielding lines were, respectively, longand short-podded.Two lines differing markedly in pod length were compared in a second experiment in 1984 in which sowing date and plant population density within a sowing date were varied. Although pod length was relatively stable, seed yield and some of its components were greatly affected by sowing date and plant density. Again, the long-podded line produced fewer pods with a greater weight of seed per pod than the short-podded line in most conditions. Compensation for greater seed weight per pod by a reduction in number of pods per plant was primarily responsible for the absence of significant differences in yield between lines in any treatment.Although long pods generally produced a greater weight of seeds per pod than short pods, the advantage in seed number and/or the weights of individual seeds was less than that expected pro rata for the much greater pod length. Indeed, short pods produced more seeds per unit length of pod than long pods. This suggested a less efficient distribution of assimilates within the longer pods, a greater amount being required to support the growth of pod walls than in short pods.Alternative approaches to using pod length as a criterion of selection for high yield are discussed.
