Abstract/ Executive Summary:

The experiment was conducted at the Pulses Reserch Centre, Ishurdi, Pabna during 2016-2017 to find out the optimum rice straw height for better growth, establishment and yield of grass pea. There were six treatments that were cutting straw height at 10 cm, 20 cm, 30 cm, 40 cm, 50 cm and Farmers practice (about 15 cm) in the experiment. Results demonstrated that40 cm rice straw height was optimum rice straw height for better growth, establishment and yield (675 kg/ha) of grass pea.

Program Area: Crop-Soil-Water Management

Commodity: Gardenpea

Objectives:

To find out the optimum rice straw height for better growth, establishment and yield of grass pea.

Methodology:

The experiment was conducted at the Pulses reserchcentre, Ishurdi, Pabna during 2016-2017 to find out the optimum rice straw height for better growth, establishment and yield of grass pea. There were six treatments that were cutting straw height at 10 cm, 20 cm, 30 cm, 40 cm, 50 cm and Farmers practice (about 15 cm) in the experiment. The experiment was laid out in a randomized complete block design with three replications. The unit plot size was 5m x 5 m. The crop was sown on 09 November 2016 (15 days before harvest of T.aman rice). Rice was harvested retaining about 25 cm tall stubbles after 15 days of seed sowing. The fertilizers were used @ 20-20-20 NPK kg ha^-1. One third nitrogen and full amount of other fertilizer were applied as basal before broadcasting of grass pea. Rest of the nitrogen was top dressed after rice harvesting. Rovral @ 2g/Lwas sprayed two times for controlling diseases at flowering and podding stage. Grasspea harvesting date was on 30 March 2017. Data on yield contributing characters were recorded from 5 randomly selected plants from each plot and grain yield (kg/ha) were recorded from the whole plot after harvest. Data on yield and yield contributing characters were taken and analyzed statistically with MSTAT-C program. The mean values were adjusted by LSD at 0.05 levels of probability.

Achievement/Findings:

Among all levels of straw retentions, the 40 cm rice straw height performed well in increasing growth and yield of grass pea. However, the experiment needs to be continued for the next year for drawing concrete conclusion.
