Abstract/ Executive Summary:

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to examine the effect of variety and culture method on the yield and yield components of wheat. Four varieties viz. Kanchan, Protiva, Gourab and Sotabdi and two culture methods viz. bed planting and conventional method were included as experimental treatments. From the study it was found that the different varieties significantly influenced the grain yield, straw yield, number of tillers plant^-1, number of effective tillers plant^-1, number of filled grains spike^-1 and 1000 grain weight. These characters were also significantly influenced by the culture method. The variety Sotabdi produced the highest grain yield (2.94 t ha^-1) and Kanchan produced the lowest grain yield (1.44 t ha^-1). Higher grain yield (1.97 t ha^-1) was produced by bed planting method than conventional method. The interaction effect of variety and culture method had significant influence on all the crop characters except few. All the variety gave higher yield under bed planting method and the variety Satabdi gave the higher grain yield (2.31 t ha^-1). It is concluded that bed planting is better culture method for wheat production.

Start Date: 00-11-2004

End Date: 00-03-2005

Program Area: Crop-Soil-Water Management

Commodity: Wheat

Objectives:

1. To know the effect of variety and culture method on the yield and yield attributes of wheat under conventional and raised bed method of culture.
2. To assess the performance of bed planting as a resource conservation technology in wheat cultivation.

Methodology:

The experiment was carried out at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from November 2004 to March 2005. The experimental field was a medium high land with loamy textural soil having pH value of 6.8. Status of nitrogen and phosphorus and cation exchange capacity were medium. The experiment was laid out in two factorial randomized complete block design (RCBD) with three replications. The experiment comprised four varieties viz. Kanchan (V₁), Protiva (V₂), Gourab (V₃) and Sotabdi (V₄) and two culture methods viz. bed planting (T₁) and conventional method (T₂). The experimental field was prepared conventionally and the raised bed with furrows was made by spade. The bed size was 40 cm in width, 15 cm in depth with 30 cm furrows. The land was uniformly fertilized with 220-180-75 kg ha^-1 N, P₂O₅ and K₂O in the form of urea, triple super phosphate and muriate of potash respectively. One third of urea and all other fertilizers were broadcasted and incorporated into the soil at the time of final land preparation. The remaining urea was top dressed in two equal splits. The first split was applied at crown root initiation stage (21 days after sowing) and 2^nd at maximum tillering stage followed by irrigation. Seeds were sown continuously by hand on bed and conventional method with two rows and 25 cm row spacing along with all other intercultural operations were conducted to ensure a healthy crop stand in the field. Data on yield and yield attributing characters were recorded at harvest. Recorded data were analyzed following the ANOVA technique and mean differences were adjudged by Duncan’s New Multiple Range Test (DMRT) with the help of computer package M-STAT-C.

Achievement/Findings:

Among used 4 varieties of wheat Sotabdi gave highest yield attributing characters like number of tillers plant^-1, number of effective tillers plant^-1, number of filled grains spike^-1 and 1000 grain weight as well as it produced highest grain yield . The bed planting method showed better performance than conventional method. So farmers may adopt Sotabdi variety in bed planting method.
