Abstract/ Executive Summary:

A field experiment was conducted at farmer's field in Rajshahi (Godagari) during November 2007 to April 2008 with the objective to find out the effect of zinc on the yield and yield contributing characters of three chickpea genotypes. Two set of treatments were imposed as; (A) cultivar: 3 (Binasola-4, Binasola-3 and Hyprosola) and (B) doses of zinc: 5 (control, I.5, 2.0, 2.5, and 3.0 kg ha^-1). The application of I.5, 2.0 and 2.5 kg ha^-1 of Zn fertilizer gave significantly higher seed yield (2.24, 2.48 and 2.29 t ha^-1, respectively) over control. On the other hand, seed yield decreased to 2.15 t ha^-1 by the application of 3.0 kg ha^-1 of Zn fertilizer. Yield increased at 1.5, 2.0 and 2.5 kg ha^-1 of Zn were 9.26%, 20.97% and 11.70%, respectively over control. Thus, the results indicated that application of Zn at 1.50-2.0 kg ha^-1 in chickpea were better for achieving higher seed yield for all the tested varieties.

Keywords: Chickpea cultivar, Yield, Zinc fertilizer

Start Date: 00-11-2007

Program Area: Crop-Soil-Water Management

Commodity: Chickpea, Fertilizer

Objectives:

To evaluate the effect of zinc fertilizer on the yield and yield contributing characters of chickpea.

Methodology:

The field experiment was conducted at farmer's field in Rajshahi (Godagari) during November 2007 to April 2008 with the objective to find out the effect of zinc on the yield and yield contributing characters of chickpea. Two set of treatments were imposed as; (A) cultivars: 3 (Binasola-4, Binasola-3 and Hyprosola) and (B) doses of zinc: 5 (control, 1.5, 2.0, 2.5, and 3.0 kg ha^-1). The experiment was laid out in a split plot design with 3 replications. The entire experimental field was divided into three blocks. Each block was divided into three main plots and each main plot was divided into five sub plots. Thus, the total number of plots of the experiment was 45 (3 x 5 x 3). The varieties were placed in the main plots and the fertilizers were placed in the sub plots. The land was opened with a power tiller plough. Subsequent ploughing and cross-ploughing were done with power tiller followed by cleaning and removal of weeds. The land was left as such for a few days for operation and conditioning. The land was again ploughed, laddered and cleaned of remaining stubbles and weeds. After making layout of the experiment, the land was fertilized @ 20.0, 25.0, 28.0 and 10.0 kg ha^-1, as N, P, K and S, respectively. Five doses of zinc were used, such as; control, l.5, 2.0, 2.5 and 3.0 kg ha^-1. The sources of the N, P, K, Sand Zn fertilizers were urea, triple super phosphate, muriate of potash, gypsum and zinc sulphate, respectively. The fertilizers were used in the experimental plots following the fertilizer recommendation guide. All the fertilizers were applied as basal at the time of final land preparation. Seeds were sown on 15 November 2007 @ 40 kg ha^-1. Before sowing, seeds were mixed with fungicide (Vitavax 200 @ 2 g kg^-1 seed). Seeds were sown in furrows by hand maintaining uniformity as much as possible. Line to line distance was maintained as 60 cm. Then the seeds were covered with soil to have a good seed soil contact. All the plant characters were recorded from ten randomly selected plants, except seed yield. Seed and stover yield was collected from the whole plot and converted into t ha^-1. Data were compiled and analyzed using MSTAT computer package and the mean values were judged by DMRT .
