Abstract/ Executive Summary:

An experiment was conducted to investigate into the effect of row spacing and seed rate on crop characters, yield attributes and yield of mustard. The experiment comprised three row spacing viz., 15, 30 and 45 cm, and four seed rates viz., 4, 6, 8 and 10 kg ha^-1. The siliqua number plant^-1 and seed yield plant^-1 increased with increasing row spacing while number of siliqua m^-2 as well as seed yield m^-2 decreased with increasing row spacing. Results further showed that siliqua number plant^-1, siliqua length, seeds siliqua^-1, 1000-seed weight and seed yield plant^-1 decreased with increasing seed rate. For unit area basis, number of siliqua m^-2 as well as seed yield m^-2 increased with increasing seed rate till 8 kg seeds ha^-1 but yield was the highest in 6 kg seeds ha^-1 (215 g m^-2) and these two parameters (number of siliqua m^-2 and seed yield m^-2) were statistically similar between 6 and 8 kg seeds ha^-1. In case of interaction between row spacing and seed rate, 30 cm row spacing with 6 kg seeds ha^-1 produced the maximum seed yield.

Location: Research farm, Bangladesh Agricultural University, Mymensingh

Start Date: 10-11-2007

End Date: 23-02-2008

Program Area: Crop-Soil-Water Management

Commodity: Mustard

Objectives:

To study the effect of row spacing and seed rate on the yield and yield components of Binasarisa-4; and to observe the interaction effect of spacing and seed rate on yield and yield contributing characters of mustard cv. Binasarisa-4.

Methodology:

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from November 2007 to February 2008 to investigate the effect of row spacing and seed rate on crop characters, yield attributes and yield of mustard. The experiment comprised three row spacing viz., 15, 30 and 45 cm, and four seed rates viz. 4, 6, 8 and 10 kg ha^-1. The experiment was laid out in two factors split-plot design with three replications where row spacing was placed at main plot and seed rate placed at sub-plot. Urea, triple super phosphate (TSP), muriate of potash (MP), gypsum and borax were used as source of nitrogen, phosphorus, potassium, sulphur and boron, respectively. The doses of fertilizers were 240, 180, 80, 140 and 10 kg ha^-1 for urea, TSP, MP, gypsum and borax, respectively. Total amount of TSP, MP, gypsum, borax and 50% of urea were applied at basal doses during final land preparation. The remaining 50% urea was applied as top dressing at 21 days after sowing (DAS) during flower initiation stage. Recommended cultural practices were followed. At harvest, yield components were recorded from 10 plants of eah plot. The plot yield converted into kg/ha. Data on plant characters were recorded from the five plants of each replication except seed and stover yield. The collected data were analyzed statistically.

Achievement/Findings:

The seed rate of 6 kg ha^-1 with 30 cm row spacing appears to be the best among the treatments regarding yield of mustard under the AEZ-9, which can be practiced in this area for better benefits.
