Abstract/ Executive Summary:

The experiment was conducted to study the effect of sowing depth on the yield of spring wheat. The experiment consisted of two factors i.e. three sowing depth viz. 2 cm, 4 cm, 8 cm and two modern wheat varieties viz. Bijoy and Prodip. A randomized complete block design was adopted with three replications. Results indicated that the effect of sowing depth was significant on almost all the parameters except spike length. Sowing on 4 cm depth gave the highest grain yield (3.88 t ha^-1) followed by 2 cm (3.75 t ha^-1) and 8 cm sowing depth (3.62 t ha^-1). Significant variation was found due to different varieties in respect of all the parameters studied. Bijoy produced the highest grain yield (3.92 t ha^-1) and the lowest one was produced by Prodip (3.57 t ha^-1). Bijoy produced the highest grain yield (4.06 t ha^-1) when sown on 4 cm depth.

Commodity: Wheat

Objectives:

1. To study the effect of sowing depth on the yield of spring wheat.

Methodology:

The present research work was carried out at the Agronomy Field Laboratory, Department of Agronomy and Agricultural Extension, University of Rajshahi during the period from November, 2011 to April, 2012 to study the effect of sowing depth on the yield of spring wheat. The experiment consisted of two factors i.e. sowing depth viz. 2 cm, 4 cm, 8 cm and wheat varieties viz. Bijoy and Prodip. A randomized complete block design was adopted with three replications. The size of the each unit plot was 3m × 4m. The experimental field was fertilized with urea, TSP, MoP and gypsum at the rate of 220,180, 50, 120 kg ha^-1. One third of urea and all other fertilizer were applied during the final land preparation. The second one third urea applied at 21 days after sowing and last one third at second irrigation. All the applied fertilizers were thoroughly mixed to the soil. Wheat seeds were sown on 2 cm, 4cm and 8 cm depth on 29 November, 2011 at the rate of 120 kg ha^-1 with 25 cm apart rows opened by specially made in iron hand tine. Two weeding at 21 and 52 days after sowing were done before fertilizer application to control weeds in the experimental field. Thinning was done followed by first weeding for maintaining 5 cm apart from plant to plant. Two irrigations were applied. First irrigation was applied at 21 days after sowing and second irrigation at 53 days after sowing followed by weeding. Data on yield and yield contributing characters were recorded. The data were compiled and tabulated for statistical analysis. The data were analyzed statistically and the mean differences among the treatments were adjudged by Duncan’s Multiple Range Test with the help of MSTATC software.
