Abstract/ Executive Summary:

The experiment was conducted at RARS, Jamalpur during Kharif-1 season of 2016 to find out optimum rates of boron for growth and yield of blackgram. The experiment was laid out in RCBD with three replications.The treatments were T₁= Control, T₂ = 20-20-20-10-2-0.5 kg NPKSZnB/ha^-1, T₃= 20-20-20-10-2-1.0 kgNPKSZnB/ha^-1, T₄=20-20-20-10-2-1.5 kg NPKSZnB/ha^-1, T₅=20-20-20-10-2-2.0 kg NPKSZnB/ha^-1, T₆=20-20-20-10-2-2.5kg NPKSZnB/ha^-1. Application of B on blackgram ponded positively and contributed to achieve higher yield over control treatment in different extent. Treatment T₃= 20-20-20-10-2-1.0kg NPKSZnB/ha^-1 and T₄= 20-20-20-10-2-1.5kg NPKSZnB/ha^-1 gave the highest and similar seed yield 1211 kg/ha that was 20 % higher than the control treatment. So, it may be coucluded that application of 1.0 kg boron ha^-1 with a blanket does of 20-20-20-10-2 NPKSZn ha^-1was suitable for successfully blackgram cultivation in Jamalpur region.

Location: Regional Agricultural Research Station, Jamalpur

Start Date: 00-00-2016

End Date: 00-00-2016

Program Area: Crop-Soil-Water Management

Commodity: Black gram, Soil fertility

Objectives:

To study the requirement of boron on the growth and yield of blackgram.

Methodology:

The experimental site was of medium high land belonging to the Old Brahmaputra Flood plain under Agro-Ecological Zone 9 (UNDP & FAO, 1988). The experiment was conducted at the Regional Agricultural Research Station, Jamalpur during Kharif-II season of 2016 find out the effect boron on the of growth and yield and optimum rates of boron for blackgram. Design of the experiment was RCB with 3 replications. Each treatment was sown in unit plot having 3m × 4m with the spacing of 30 cm between rows. Spacing between two plots and replications to replication were 1m and 1.5m respectively. BARI Mash-3 was used as a variety in the experiment. Treatments included in the experiment were: T₁=20-20-20-10-2 kg NPKSZn/ha^-1, T₂=20-20-20-10-2-0.5 kg NPKSZnB/ha^-1, T₃=20-20-20-10-2-1.0 kg NPKSZnB/ha^-1, T₄=20-20-20-10-2-1.5 kg NPKSZnB/ha^-1, T₅= 20-20-20-10-2-2.0 kg NPKSZnB/ha^-1, T₆=20-20-20-10-2-2.5 kg NPKSZnB/ha^-1. Seeds were sown on September 01, 2016 and harvested on at 2^nd November 2016 maintaining 30 row distances in continuous line. Weeding was done at 20 days after emergence of the crop. Grain yield was calculated from the whole plot. Yield contributing characters were taken from 10 randomly selected plants from the middle rows of each plot. Data were analyzed with the help of a computer package program STAR and means were separated following LSD test at 5% level of significance.

Achievement/Findings:

Considering the yield performance, it may be concluded that application of boron @ 1.0 kg ha^-1 blackgram produced higher seed than other fertilizer treatments with a blanket dose 20-20-20-10-2 kg NPKSZn ha^-1 was suitable for successfully Blackgram cultivation in Jamalpur region.
