The experiment was conducted at the Agronomy Field laboratory, Department of Agronomy, Bangladesh Agricultural University, Mymensingh to evaluate the effect of variety and boron on the growth and yield of French bean (Phaseolus vulgaris L.) during November 2017 to March 2018. The experiment was comprised two factors involving three varieties viz. BARI Jharseem-1, BARI Jharseem-2, BARI Jharseem-3, and four Boron doses viz. 0 (No boron), 0.5, 1.0 and 1.5 kg B ha-1. Borax was used as a source of boron. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The result exhibited that yield and its contributing characters were significantly influenced the variety and boron applications. The experimental findings revealed that the highest number of pods plant-1 (4.73), effective pods plant-1 (4.01), seeds pod-1 (3.98), 1000-seeds weight (416.53g), seed yield (1.53 t ha-1), stover yield (2.69 t ha-1), biological yield (4.22 t ha-1), and harvest index (36.03%) were highest for the variety BARI Jharseem-3. At the same time, highest number of pods plant-1 (5.02), number of effective pods plant-1 (4.03), number of seeds pod-1 (4.04), 1000-seed weight (412.74 g), seed yield (1.54 t ha-1), stover yield (3.05 t ha-1), biological yield (4.59 t ha-1), and harvest index (36.98 %) were recorded under boron level at 1.5 kg ha-1. Again incase of interaction of variety and boron, highest number of pods plant-1 (4.95), number of effective pods plant-1 (3.98), number of seeds pod-1 (3.69), 1000-seeds weight (413.15g), seed yield (1.76 t ha-1), stover yield (3.11 t ha-1), biological yield (4.87 t ha-1) and harvest index (37.19%) were recorded in BARI Jharseem-3 under boron level 1.5 kg ha-1. Plant dry matter found positively correlated (r2=0.8126) with seed yield. So, it may be concluded from this experiment that cultivation of var. BARI Jharseem-3 along with 1.5 kg B ha-1 could be applied to obtain higher yield of French bean.
Wheat is facing increased high temperature during its grain filling period in Bangladesh which reduces yield drastically. Mulching may help to mitigate this problem. Therefore, a field experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from November 2015 to March 2016 to find out growth and yield performance of wheat as influenced by mulching. The experiment comprised of two factors viz., variety and mulching. The variety comprised of BARI Gom-26, BARI Gom-27 and BARI Gom-28. Mulching comprised of four different levels of treatments viz.no mulch + no irrigation (control), water hyacinth mulch + no irrigation, rice straw mulch + no irrigation and two irrigations at CRI and flowering stage. The experiment was laid out in a randomized complete block design with three replications. BARI Gom-28 showed the highest values in growth parameters (plant height, number of total tillers hill -1 , LAI, chlorophyll content and total dry matter) at 30, 45 and 60 DAS. On the other hand, when mulching was compared, rice straw mulch gave higher yield compared to other treatments at 30, 45 and 60 DAS. The interaction effect of variety and mulching showed significant in relation to yield and yield components except plant height, spike length, 1000-grain weight and harvest index (%). The tallest plant (93.20 cm) was obtained from the interaction of BARI Gom-28 and rice straw mulch. The highest number of total tillers hill -1 (4.80), number of effective tillers hill -1 (4.57), spike length (10.23), number of spikelets spike -1 (21.15), 1000-grain weight (48.54 g), grain yield (5.20 t ha -1 ), straw yield (7.27 t ha -1
