Abstract/ Executive Summary:

A field experiment was carried out at the Bangladesh Institute of Nuclear Agriculture (BINA) sub-station farm, Ishurdi during the rabi season of 2007-’08 to find out the optimum date of sowing of chickpea varieties. The treatments of the experiment were; four sowing dates (November 1, November 15, December 1 and December 15) and three varieties (Binasola-4, Binasola-3 and Hyprosola). The results of four dates of sowing demonstrated that early sowing (November 1 and November 15) produced the highest number of branches plant^-1, pods plant^-1, seeds pod-1 and seed yield (1991-2085 kg ha^-1). Late sowing (December 1 and December 15) produced the shortest plant height, lowest number of branches and pods plant^-1 and seeds pod-1, smallest size of seed and lowest seed yield. Among the different varieties, Binasola-4 produced higher seed yield (2085 kg ha^-1) followed by Binasola-3 (2036 kg ha^-1) in November 15 sowing.

Keywords: Sowing date, Chickpea, Seed yield

Location: BINA sub-station farm, Ishurdi

Start Date: 00-11-2007

End Date: 00-04-2008

Program Area: Crop-Soil-Water Management

Commodity: Chickpea

Objectives:

To evaluate the effect of date of sowing on the yield and yield contributing characters of chickpea.

Methodology:

The experiment was conducted at the BINA sub-station farm, Ishurdi during November 2007 to April 2008 to find out the optimum sowing date of chickpea varieties. Treatments were; four sowing dates (November 1, November 15, December 1 and December 15) and three varieties (Binasola-4, Binasola-3 and Hyprosola). The experiment was laid out in a split plot design with three replications. The entire experimental field was divided into three blocks and each block was divided into four main plots and each main plot was divided into three sub plots. The total plots of the experiment were 36 (3 × 4 × 3). The size of each plot was 3 m × 4 m. The sowing date was placed in the main plots and the varieties were placed in the sub-plots. After making lay out of the experiment, the lands were fertilized. Chemical fertilizers were applied @ 25.0, 23.0, 28.0, 10.0, and 1.0 as N, P, K, S and Zn from urea, triple super phosphate, muriate of potash, gypsum and zinc sulphate ha^-1, respectively. The fertilizers were used in all the unit plots using Fertilizer Recommendation Guide. The full dose of N, P, K, S, and Zn were applied as basal at final land preparation. Seeds were sown on November 1, November 15, December 1 and December 15, 2007 @ 40 kg ha^-1. To avoid the contamination; seeds were treated with fungicide vitavax 200 @ 2 g kg^-1 seed before sowing. The 50 cm apart furrows with 4 cm depth were made with hand tine for sowing seed. Healthy seeds were sown by hand as uniformly as possible in furrows. The seeds were covered with soil to have a good seed-soil contact. The cultural practice such as weeding was done two times i.e. 25 and 45 days after sowing. Thinning was done on the same date of first weeding to maintain plant to plant distance of 10 cm. A light irrigation was given immediately after sowing. To control pod borer, Ripcord at the rate of 10 ml/10 litre water and to control root rot disease fungicide, Ridomil MZ 72 at the rate of 25 g/10 litre water were sprayed two times at 60 and 75 days after sowing. Data on yield contributing characters were recorded from ten randomly selected plants. The yield was taken from whole plots and converted in kg ha^-1. Data were compiled and analyzed throught MSTAT computer package and the mean values were judged by DMRT.
