Abstract/ Executive Summary:

An experiment was carried out at the Bangladesh Institute of Nuclear Agriculture (BINA) sub-station farm, Ishurdi during November 2007 to April 2008 to evaluate the effect of phosphorus with biofertilizer on the growth and yield of chickpea. The results of phosphorus and biofertilizer trial demonstrated that biofertilizer had markedly positive influence on the production of nodules, dry weight of nodules, pods plant^-1, seeds pod^-1, 1000-seed weight, grain yield, stover yield and harvest index. Binasola-3, Hyprosola and Binasola-4 in combination with biofertilizer produced the highest nodule number (27.37, 25.73 and 25.6, respectively) in chickpea. Inoculation of biofertilizer produced higher seed yield (2608, 2518 and 2517 kg ha^-1 by Hyprosola, Binasola-4 and Binasola-3, respectively).

Keywords: Phosphorus, Biofertilizer, Chickpea seed yield, Introduction

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 phosphorus with biofertilizer on the growth and yield of chickpea.

Methodology:

The experiment was conducted at the BINA sub-station farm Ishurdi during November 2007 to April 2008 to evaluate the effect of phosphorus and biofertilizer on growth and yield in chickpea. Two set of treatments were imposed as; (A) Varieties: 3 (Binasola-4, Binasola-3 and Hyprosola) and (B) Fertilizer doses: 5 (Control i.e. recommended fertilizer, biofertilizer and 30, 60 and 90 kg P₂O₅ ha^-1). The experiment was laid out in a split plot design with 3 replications. The entire experimental field was divided into three blocks and each block was divided into three main plots and each main plot was divided into five sub-plots. The total plots of the experiment were 45 (3 × 5 × 3). The varieties were placed in the main plot and the fertilizer doses were placed in the sub-plots. After making lay out of the experiment, the lands were fertilized. The phosphorus fertilizer doses were 30, 60 and 90 kg P₂O₅ ha^-1 as triple super phosphate. The recommended chemical fertilizers were applied @ 20.0, 28.0, 10.0, and 1.0 kg as N, K, S and Zn per hectare, respectively as recommended by the Fertilizer Recommendation Guide in the form of urea, muriate of potash, gypsum and zinc sulphate, respectively. All the fertilizers were applied as basal at the time of final land preparation. Biofertilizer was mixed @ 40 g kg^-1 seed with molasses and then the seeds were kept in the mixture and stirred by hand for few minutes. A black coating was formed around the seed surface and the seeds were dried under a shed before sowing. Seeds were sown on November 15, 2007 @ 40 kg ha^-1. Before sowing, seeds were mixed with fungicide (vitavax 200 @ 2 g kg^-1 seed). Seeds were sown by hand as uniformly as possible in furrows. Line to line distance was 60 cm. Then the seeds were covered with soil to have a good seed-soil contact. Fresh nodules plant-1 (no.) was collected at 45 days after sowing. Dry weight of nodules (mg) and the other plant characters were recorded from ten randomly selected plants. Data were compiled and analyzed through MSTAT computer package and the mean values were judged by DMRT.

Achievement/Findings:

The findings of experiment with biofertilizer inoculation in chickpea yield increased (2.04 t ha^-1) with the application of P fertilizer up to 60 kg ha^-1. In the present study, chickpea yield increased slightly by application of 90 kg of P₂O₅ ha^-1. So, it can be concluded that 60 kg P₂O₅ is economically profitable for chickpea.
