Abstract/ Executive Summary:

This study was conducted to evaluate the performance of blackgram (Vigna mungo L) under various levels of nitrogen at the Agronomy Research Site of Bangabandhu Sheikh Mujibur Rahman Agricultural University during March to June 2002. Two varieties of blackgram- BARI mash 3 and BINA mash 1 and six levels of nitrogen i.e., 0, 20, 40, 60, 80 and 100 kg N ha^-1 were the treatment variables. Different morphological characters including grain yield were affected significantly by the nitrogen levels. The longest plant was measured with 100 kg N ha^-1 whereas largest leaf area was obtained with 80 kg N ha^-1. BINA mash 1 was longer than BARI mash 3. Yield and yield contributing characters were affected significantly by different levels of nitrogen. The highest grain yield was obtained with 60 kg N ha^-1 in both the varieties, thereafter the grain yield declined. Application of 60 kg N ha^-1 favored most of the yield contributing characters that contributed the maximum grain yield production at this level of N.

Location: Gazipur

Start Date: 03-03-2002

End Date: 15-06-2002

Program Area: Crop-Soil-Water Management

Commodity: Black gram

Objectives:

This study was therefore undertaken aimed to evaluate the beneficial effect of different levels of nitrogen alone and in combination with variety on plant height, leaf area development, yield and yield contributing characters of blackgram.

Methodology:

A field experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during Kharif -1 season (from March to June 2002). The soil of the experimental field was silty clay under salna series with pH 6.5. The experimental soil contains 0.159% total N, 0.619% organic carbon, 0.312 meq exchangeable P/100 g soil, 0.38 meq exchangeable K/100 g soil and CEC 22.54 meq/100 g soil. The experimental site is situated in a subtropical environment having frequently rainfall during March to June. The experiment was laid out in a factorial RCBD with 3 replications. Treatment combination: Two varieties of blackgram with six level of nitrogen fertilizer constituted the following treatment combinations. B1 N0: BARI mash-3 with 0 kg ha^-1 level of nitrogen fertilizer; B1 N20: BARI mash-3 with 20 kg ha^-1 level of nitrogen fertilizer; B1 N40: BARI mash-3 with 40 kg ha^-1 level of nitrogen fertilizer; B1 N60: BARI mash-3 with 60 kg ha^-1 level of nitrogen fertilizer; B1 N80: BARI mash-3 with 80 kg ha^-1 level of nitrogen fertilizer; B1 N100: BARI mash-3 with 100 kg ha^-1 level of nitrogen fertilizer; B2 N0: BINA mash-1 with 0 kg ha^-1 level of nitrogen fertilizer; B2 N20: BINA mash-1 with 20 kg ha^-1 level of nitrogen fertilizer; B2 N40: BINA mash-1 with 40 kg ha^-1 level of nitrogen fertilizer; B2 N60: BINA mash-1 with 60 kg ha^-1 level of nitrogen fertilizer; B2 N 80: BINA mash-1 with 80 kg ha^-1 level of nitrogen fertilizer and B2 N100: BINA mash-1 with 100 kg ha^-1 level of nitrogen fertilizer. The data recorded on different plant characters were statistically analyzed with the help of MSTAT program. The differences between the treatment means were compared by Least Significant Difference (LSD) test (Gomez and Gomez, 1983).

Total Budget (Tk.) : 16000

Achievement/Findings:

Between the two varieties of blackgram, BARI mash 3 out yielded BINA mash 1 at all levels of nitrogen. It was obvious that grain yield of blackgram can be increased substantially with the judicious application of N.
