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.

Mungbean can successfully be grown under strip tillage system if appropriate seeding rate can determine and adjust with machine. Due to high weed pressure in strip tillage system, selection of such mungbean varieties that have some potentialities to suppress weeds need to find out and moreover, determining optimum seed rate for different varieties could help to achieve best yield. Therefore, a study was conducted at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during March-June, 2013 to study the effect of variety and seed rate on weed suppression and yield performance of mungbean under strip tillage system. The study comprised three mungbean varieties (BARI mung-6, BINA mung-5 and BINA mung-8) and five seed rates (20, 25, 30, 35 and 40 kg ha-1). The experiment was laid out in split-plot design with three replications. The study exposed that variety and seed rate had significant effect on plant population of mungbean, weed dry matter, number of pods plant-1, pod length, number of seeds pod-1, seed yield and stover yield of mungbean. The study results clearly found that weed population significantly reduced with increasing seeding rate of mungbean. Seeding of mungbean at 40 kg ha-1 and 35 kg ha-1 could successfully suppress weed under strip tillage system. Moreover, BINA mung-8 and BINA mung-5 had the more potentiality to suppress weeds compare to BARI mung-6. However, BINA mung-5 was found the superior among the three tested varieties that produced the highest seed yield from 35 kg ha-1 seed rate. In case of BARI mung-6 and BINA mung-8, maximum seed yield was also obtained from 35 kg ha-1 seed rate. Therefore, the study concluded that seeding of any of the three mungbean varieties at 35 kg ha-1 rate may help to obtain the satisfactory yield but the study suggest cultivation of BINA mung-5 at 35 kg ha-1 seeding rate under strip tillage system that will give not only the optimum seed yield but also provide good weed suppression.J.

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).

SUMMARYField trials are described in which the seed yield response of row-sown sesame to increasing plant population was examined, and in which row-sowing was compared with broadcasting at different seed rates. Maximum yields were obtained at an intended 200 to 250 × 103 plants ha−1 but yields were not greatly affected by a wider range of populations. Broadcasting, the normal local practice, gave yields slightly higher than those from rows 50 cm apart, the un-thinned rate of 800 × 103 viable seeds sown ha−1 yielded as well as treatments thinned to the optimum population, and double this seed rate, unthinned, gave the lowest yields, especially in rows.

A field experiment was conducted at District Seed Farm, Kalyani, Bidhan Chandra Krishi Viswavidyalaya (22.97oN, 88.43oE, 9.75m MSL), Nadia, West Bengal, India during rabi season of 2014-16 to identify the optimum seed rate and variety for relay cropping with transplanted long duration kharif rice under changing onset of monsoon. The experiment was laid down in split plot design with three replications comprising of three lentil varieties (PL6, WBL 77 and NDL 1) in main plot and four seed rates (50, 60, 70 and 80 kg ha-1) in sub-plot. The varieties and seed rates significantly affected the plant population, pods per plant, biological and seed yield. The lentil variety PL 6 recorded highest seed yield (1446.8 kg ha-1) with the seed rate of 60 kg ha-1 followed by WBL 77 and NDL 1. Among the varieties PL6 recorded highest test weight (27.58 g) followed by NDL 1 (18.36 g) and WBL 77 (16.20 g). The variety PL 6 exhibited highest seed yield which was mainly attributed by the highest test weight of seeds along with moderate plant population m-2 and number of pods plant-1.

Effect of detopping and mepiquat chloride on morphological, physiological and yield attributes of soybean cultivar ‘SL 544’ was studied. A two year investigation was conducted at Punjab Agricultural University, Ludhiana, during kharif seasons of 2014 and 2015. The experiment was laid-out in randomized complete block design (RCBD) with eight treatments viz. control, detopping (removal of 4-5 cm apical portion of main stem) at 50-55 days after sowing (DAS), mepiquat chloride @ 200 ppm (50-55 DAS), mepiquat chloride @ 200 ppm (50-55 + 65-70 DAS), mepiquat chloride 250 ppm (50-55 DAS), mepiquat chloride @ 250 ppm (50-55 + 65-70 DAS), mepiquat chloride @ 300 ppm (50-55 DAS) and mepiquat chloride @ 300 ppm (50-55 + 65-70 DAS) with four replications. Detopping had a non-significant effect on leaf area index, SPAD value, PAR interception, abscission of reproductive parts, seeds per pod, 100-seed weight, pod length and stover yield of soybean. It significantly decreased plant height, increased total dry matter accumulation/plant, number of flowers and pods/plant, pod setting percentage and seed yield over control during 2014 and 2015. At crop harvest, detopping developed optimized source-sink relationship by means of distribution of total dry matter between stem, foliage and pods by 20.4, 14.9 and 64.6 % during 2014 while 22.6, 20.1 and 57.4 % during 2015, respectively. Mepiquat chloride posed a non-significant effect on plant height, PAR interception, number of flowers/plant, number of seeds/pod, pod length and stover yield of soybean but it significantly decreased leaf area index, abscission of reproductive parts while increased the dry matter accumulation/plant, number of pods/plant, 100-seed weight and seed yield relative to control. At harvest, two foliar applications of mepiquat chloride @ 250 ppm resulted in optimized source-sink relationship by the distribution of total dry matter among stem, foliage and pods by 20.6, 10.9 and 68.5 % during 2014 while 19.5, 7.6 and 72.9 % during 2015, respectively. Occurrence of more rainfall during 2015 as compared to 2014 caused mepiquat chloride to hike seed yield as compared to detopping which is clearly witnessed by increase in pod dry weight per plant during 2015 than 2014. Conclusively, both detopping and mepiquat chloride resulted in enhancement in source-sink relationship and seed yield of soybean.

An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during October 2014 to March 2015 to study the growth and yield performance of field pea varieties as influenced by date of sowing. The experiment comprised of two factors namely, date of sowing and variety. Date of sowing comprised of 29 October, 13 November and 28 November and the variety comprised of BARI motor-1, BADC motor-1, Natore local and Narail local. The experiment was laid out in a split plot design with three replications. The results indicate that all the growth characters were varied significantly at different days after. Those growth characters except leaf area index were highest for the crop sown on 28 November. The growth characters were highest in variety Natore local and lowest in Narail local except dry matter it was lowest in BADC motor-1. The interaction effect of 28 November sowing, Natore local was highest for all of the growth parameters except leaf area index it was highest on 13 November sowing and the interaction on 29 October sowing BARI motor-1 gave the lowest value. Most of the yield contributing parameters significantly affected by sowing date. The highest seed yield (827.7 kg ha-1) and other yield contributing characters were found on early sowing (13 November) and the lowest seed yield (534 kg ha-1) and other yield contributing characters was at 28 November sowing. Variety had significant effect on yield and yield contributing parameters. The highest seed yield (1032.2 kg ha-1) and Stover yield (3221.35 kg ha-1) was obtained from Natore local while Narail local gave lowest (469.1 kg ha-1) seed yield and lowest Stover yield. The interaction of 13 November with Natore local gave the highest seed yield (1319.3 kg ha-1) and lowest seed yield was produced by Narail local (330.35 kg ha-1) by late sowing (28 November). It can be concluded that, vegetative growth were highest at 28 November sowing and yield components gave highest value on 13 November sowing. Highest yield was produced by Natore local at 13 November sowing but yield was reduced drastically when the crop sown on 28 November. So, it is clear that the optimum date of sowing for field pea is at 13 November.

The experiment was conducted to study the response of lentil to irrigation levels and different methods of boron application in relation to yield and yield contributing characters. Three levels of irrigation viz., I0: control (No irrigation), I1: one irrigation at 25 days after sowing (DAS), I2: two irrigations at 25 DAS and 40 DAS, and four levels of Boron viz., B0: control (No boron), B1: 80% recommended dose (RD) as basal + rest 20% as a foliar spray (FS) at pre-flowering (PF), B2: 60% RD as basal + rest 40% as FS at PF, B3: 40% RD as basal + rest 60% as FS at PF as treatment variables. It was found that the highest number of pods plant-1, number of seeds pod-1, 1000-seed weight, pod length, seed yield and stover yield was obtained with two irrigations. In contrast, B3 had a significant effect on the yield contributing characters of lentil. Results also revealed that numerically more seed yield (638.23 kg ha-1) was recorded in I2B3. Similar trend was found in case of stover yield (751.26 kg ha-1) and biological yield (1389.4 kg ha-1) from I2B3 combinations. These results suggested that combined application of irrigation at 25 and 40 DAS and boron at 40% RD as basal + rest 60% as FS at PF significantly enhanced the crop yields of lentil.

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.
