Effect of Sowing Dates on Yield of Soybean in High BARInd Tract

Chief Scientific Officer & Head, OFRD and Relevant Scientists of OFRD

Abstract/ Executive Summary:

A field trial was conducted at the farmer's field of FSRD site Kadamshahar, Godagari, Rajshahi during rabi season of 2014-15 to find out the suitable sowing date for soybean cultivation in rabi season under rainfed condition in High Barind Tract. BARI Soybean-5 was planted on three sowing dates: T₁ (1 Dec), T₂ (6 Dec) and T₃ (11 Dec). The experiment was laid out in RCBD with three dispersed replications. The treatment T₁ (1 Dec) produced the highest seed yield (1.88 t ha^-1) and T₃ (11 Dec) gave the lowest one (1.07 t ha^-1). Result indicated that soybean should be sown by 1 December in the High Barind Tract.

End Date: 00-00-2015

Program Area: Crop-Soil-Water Management

Commodity: Soybean

Objectives:

To find out the suitable sowing date for soybean cultivation in rabi season under rainfed condition in High Barind Tract.

Methodology:

The field experiment was conducted at Farming System Research and Development (FSRD) site, Kadamshahar, Godagari, Rajshahi during rabi season of 2014-15. The experiment was designed with three sowing dates as 1 December (T₁), 6 December (T₂) and 11 December (T₃). It was laid out in a randomized complete block design with three dispersed replications. The unit plot size was 4m x 5m. The BARI Soybean-5 was the test crop in the study. The field of soybean was prepared by power tiller and followed by laddering. During land preparation, weeds and other stubbles of previous crop were collected and removed from the land. The seed rate, sowing method and fertilizer dose were maintained as per BARI recommendation. The sources of nutrients were urea, triple super phosphate, muriate of potash, gypsum, zinc sulphate and boric acid for N, P, K, S and B; respectively. All fertilizers were applied as basal at final land preparation. Crop was harvested at its maturity. Intercultural operations viz. weeding and insecticide spray were done in order to support normal plant growth. Data on yield and yield contributing characters were recorded. Observations were made on yield components from 10 randomly selected plants per plot. The data were analyzed statistically and the mean differences were adjudged by LSD Test (Gomez and Gomez, 1984).
