Abstract/ Executive Summary:

A field experiment was conducted at FSRD site, Chabbisnagar, Rajshahi (AEZ 26, High Barind Tract) to evaluate the response or chickpea to individual nutrients (N, P. S. Zn and B) and to find out the optimum treatment combination during the rabi seasons of 2000-2001 and 2001-2002 There were two levels each of N (0 and 50 kg/ha), P (0 and 24 kg/ha), S (0 and 10 kg/ha), Zn (0 and 2 kg/ha) and four levels of B (0, 1, 1.5 and 2 kg/ha) and a blanket close of 30 kg K/ha. Inoculum was also applied in a treatment (T₃) instead of 50 kg N/ha. There was also an absolute control treatment (T₁₀). The experimental design was randomized complete block with four replications. Different nutrients had beneficial effects on the yield and yield parameters over their control and absolute control treatments. The application of B remarkably increased the grain yield up to 1 kg/ha beyond which yield decreased. The effect or inoculum (T₃) was not superior to 50 kg N/ha (T₂). The treatment T₂ (50-24-30-10-2-1 kg of N-P-K-S-Zn-B/ha) was found to be optimum for maximizing the grain yield (1.48 t/ha in 2001, 2.00 t/ha in 2002 and 1.74 t/ha in average) of chickpea.

Keywords: Nutrient management, Chickpea, Boron, Inoculum

Location: FSRD site, Chabbisnagar, Rajshahi

Start Date: 00-00-2000

End Date: 00-00-2002

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Chickpea

Objectives:

To find out the optimum fertilizer dose for chickpea production at High Barind Tract.

Methodology:

The experiment was conducted at the High Barind Tract during rabi seasons of 2000-2001 and 2001- 2002. Initial nutrient status of the experimental soil have been presented. T₁ = 0-24-30-10-2-1 kg N-P-K-S-Zn-B/ha, T₂ = 50-24-30-10-2-1 kg N-P-K-S-Zn-B/ha, T₃ = 0-24-30-10-2-1 kg N-P-K-S-Zn-B/ha + inoculum, T₄ = 50-0-30-10-2-1 kg N-P-K-S-Zn-B/ha, T₅ = 50-24-30-0-2-1 kg N-P-K-S-Zn-B/ha, T₆, = 50-24-30-10-0-1 kg N-P-K-S-Zn-13/ha, T₇ = 50-24-30-10-2-0 kg N-P-K-S-Zn-B/ha, T₈ = 50-24-30-10-2-1.5 kg N-P-K-S-Zn-B/ha, T₉ = 50-24-30-10-2-2 kg N-P-K-S-Zn-B/ha, T₁₀ = Absolute control. The experimental design was randomized complete block with ten treatments and four replications. The unit plot size was 3m x 4m. The variety Barandra (BARI Chola-3) was used in this study. The seeds were sown in the field on 17^th and 2^nd November, 2000 and 2001, respectively. The seeds were sown in line maintaining 30 cm x 15 cm spacing. The seed rate was maintained 40 kg/ha. The land was fertilized according to the treatments. All P, K, S, Zn, B and half of N were applied at the final land preparation. The rest of N was applied at the time of flowering. The crop was harvested on 22^nd and 12^th March during 2001 and 2002, respectively. The seed yield and other related data were recorded and analyzed statistically.

Achievement/Findings:

The results of the study indicated that 1.14 kg/ha B with 50-24-30-10 kg of N P K S was found to be optimum for maximizing the seed yield (1.71 t/ha) of chickpea in the High Barind Tract (AEZ-26) of Rajshahi.
