Abstract/ Executive Summary:

A field experiment was conducted at Regional Pulses Research Station, Bangladesh Agricultural Research Institute, Madaripur during rabi season of 2015-16 to estimate the effective dose of nutrients for cowpea yield maximization. Five treatments were included in the study viz. T₁ (Control), T₂ (20-20-20 NPK kg/ha), T₃(20-20-20-10 NPKS kg/ha), T₄ (20-20-20-10-2 NPKSZn kg/ha) and T₅ (20-20-20-10-2-1.5 NPKSZnB kg/ha). The yield of cowpea increased significantly due to the application of S, Zn and B. The highest seed yield (1570 kg/ha) was produced in treatment T₅(20-20-20-10-2-1.5 NPKSZnB kg/ha).

Start Date: 00-00-2015

End Date: 00-00-2016

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Cowpea

Objectives:

To estimate the effective dose of nutrients for cowpea yield maximization.

Methodology:

The field experiment was conducted at Regional Pulses Research Station, Bangladesh Agricultural Research Institute, Madaripur during rabi season of 2015-16. The trial consisted of five treatments such as T₁=Control, T₂= 20-20-20 NPK kg/ha, T₃= 20-20-20-10 NPKS kg/ha, T₄=20-20-20-10-2 NPKSZn kg/ha, T₅=20-20-20-10-2-1.5 NPKSZnB kg/ha. The initial soil status of the experimental field are presented. The experiment was laid out in Randomized Complete Block design with 3 replications. The unit plot size was 4m × 2m. All the fertilizers were applied and incorporated in the soil during final land preparation. The variety of cowpea was BARI Felon-1. Seeds were sown on the 8 December, 2015 at a rate of 50 kg ha^-1. The seeds were sown in furrows at 40 cm x 10 cm spacing at a depth of 2 to 3 cm below the soil surface. Two irrigation were applied, one at 10 DAS another 30 DAS, at flowering stage of crop. Intercultural operations such as thinning, weeding, applying insecticides were done as and necessary. The mature pods of cowpea were harvested three times at 18 March, 30 March and 6^th April, 2016. At maturity, seed yield and yield contributing characters were recorded. The collected data were analyzed statistically.

Achievement/Findings:

The effect of nutrients on the growth and seed yield of cowpea is evident that T₅(20-20-20-10-2-1.5 NPKSZnB kg/ha) showed better response than other treatments. This is the first year trial. The experiment will be continued in the next year for confirmation.
