Abstract

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from November 2007 to March 2008 to study the effect of sowing date and seed rate on the yield and yield components of two mustard varieties. The treatments included two varieties viz. BARI Sarisha-9 and BARI Sarisha-6; three sowing date viz. 10, 20 and 30 November, and three seed rates viz. 8, 10 and 12 kg seeds ha-1. The experiment was laid out in a split plot design with three replications. It was observed that the variety had significant influence on the yield and yield contributing characters except non-effective pods plant-1, non-effective seeds pod-1 and 1000-seed weight. Higher seed yield was obtained by the variety BARI Sarisha-9. The highest seed yield (1.53 t ha-1) was recorded in 10 November sowing and the lowest one was achieved in 30 November sowing. Seed rate had also significant effect on plant height, branches plant-1, pods plant-1, effective pods plant-1, pod length, no. of seeds pod-1 and seed yield. The seed rate 8 kg ha-1 produced the highest seed yield (1.49 t ha-1) and the lowest seed yield was produced by 12 kg seeds ha-1. Among the yield contributing characters only harvest index and non-effective pods plant-1 were significantly influenced by the interaction of variety and date of seeding as well as the interaction of variety and seed rate. The highest seed yield (1.63 t ha-1) was produced when BARI Sarisha-9 was sown on 10 November. In case of interaction between variety and seed rate, BARI Sarisha-9 with 10 kg seeds ha-1 produced the maximum seed yield. Results further showed that the interaction of 10 November sowing with 8 kg seeds ha-1 produced the highest seed yield (1.55 t ha-1).

Highlights

In Bangladesh context, mustard (Brassica spp.) is a popular edible oil in rural area and is considered important for improving the taste of a number of food items
In Ayurvedic medicine, it is believed that mustard oil boiled with few cloves of garlic can cure some forms of influenza (Khaleque, 1985)
Varietal performance Branches plant-1, pods plant-1, effective pods plant-1, non-effective pods plant-1 were higher in BARI Sarisha-9

Summary

Introduction

In Bangladesh context, mustard (Brassica spp.) is a popular edible oil in rural area and is considered important for improving the taste of a number of food items. Effect of sowing date and seed rate of two mustard varieties Results revealed that plant height, branches plant-1, pods plant-1, effective pods plant-1, non-effective pods plant-1, pod length, seed yield and harvest index (%) decreased with delaying date of sowing and the highest and the lowest values of above parameters were recorded in 10 and 30 November sowing, respectively (Table 1).
