Abstract/ Executive Summary:

The experiment was conducted to determine optimum seed rate and method of sowing of some newly developed mutants and varieties. The methods of sowing were broadcasting and line sowing and seed rates were 5, 8, 11 and 14 kg/ha. Results revealed that method of sowing and seed rate had no significant effect on seed yield. However, broadcasting method of sowing was relatively better than line sowing method and 5 kg seeds/ha was enough to get optimum yield.

Keywords: Rape seed, Seed rate, Method of sowing, Yield

Location: Research farm, BINA, Mymensingh

Start Date: 00-11-1985

End Date: 00-02-1986

Program Area: Crop-Soil-Water Management

Commodity: , Mustard

Objectives:

To determine the optimum seed rate and appropriate sowing method for modern rapeseed varieties under Bangladesh environment condition.

Methodology:

The experiment was conducted at BINA research farm, Mymensingh during November 1985 to February 1986. Two newly developed mutants namely BINA-1 and BINA-2 were evaluated along with two existing varieties, YS-52 and Sampad under both lone sowing and broadcasting methods. Four seed rates viz., 5, 8, 11 and 14 kg/ha were tested. The experiment was laid out in a split-plot design with three replicates having the genotypes in the main plot and method of sowing and seed rate in the sub-plot. The line to line distance was 20 cm for line sowing methods. Recommended fertilizers and cultural methods were followed. At harvest, yield and yield components were recorded. The collected data were analyzed statistically.
