Abstract/ Executive Summary:

A field experiment was conducted at PRSS, BARI, Gazipur during rabi season 2018-19 to find out the sowing method and optimum seed rate for newly released field pea variety (BARI Motor-3) for better crop growth and yield. The experiment was conducted in a randomized complete block design with three replications. There were three sowing methods- line sowing at 40 cm and 50 cm, and broadcast sowing; and three seed rates i.e., 70 kg/ha, 80 kg/ha and 90 kg/ha. It was observed that between line and broadcast sowing there was no significant difference. Among the seeding methods line sowing with 40cm gave better yield and yield attributes over other treatments. Comparing with seed rates 90 kg/ha increased plant population seeds/pod and grain yield. Seed rates @ 90 kg/ha with line sowing 40 cm performed better for of newly released field pea variety BARI Motor-3. However, this experiment will be continued for the next year for a concrete conclusion.

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Fieldpea

Objectives:

The objectives of this study are to determine the optimal plant population densities for newly release field pea variety (BARI Motor 3) grown in the Bangladesh.

Methodology:

The field experiment was conducted at PRSS, BARI, Gazipur during the rabi season of 2018-19 to find out the sowing method and optimum seed rate of newly released field pea variety (BARI Motor-3) for better crop growth and yield. The experiment was conducted in a randomized complete block design with three replications. There were three sowing methods- line sowing at 40 cm and 50 cm, and broadcast sowing; and three seed rates i.e., 70 kg/ha, 80 kg/ha and 90 kg/ha. The crop was sown on 13 November 2018 and harvested on 02 March 2019. The dimensions of the plots were 4 m x 5 m. The soil was sandy loam having pH 7.5.The fertilizers were applied @ 20-20-20 NPK kg/ha. One hand weeding was done at 25 days after sowing (DAS) for controlling the weed. Tafgor @ 2ml/L was used one time for controlling aphid at 30 DAS. Data on yield contributing characters were recorded from 10 randomly selected plants from each plot and grain yield (kg/ha) was recorded from the whole plot after harvest. The GenStat 15th Edition software package was used for all statistical analyses. The mean differences between treatments were separated by the least significant difference (LSD) at P≤ 0.05 for the measured variables.

Achievement/Findings:

The yield and yield components of field pea influence significantly among seeding methods and seed rates. SR @ 90 kg/ha X LS 40 cm sowing gave up to 60% higher yield over other treatments. It was demonstrated that there was yield benefit of seeding methods and seed rates over control. Hence, it can be concluded that the optimum seed rate of newly released field pea variety (BARI Motor-3) for better crop growth and yield is 90 kg/ha and the optimum seeding rate is line sowing with 40 cm spacing.
