Abstract/ Executive Summary:

The experiment was conducted at the Sher-e-Bangla Agricultural University farm , Dhaka, during the period of March to May, 2006 in the kharif -1 season to study the efficacy of integrated nitrogen and irrigation managements on the yield attributes and yield of blackgram (cv. BARI mash- 3).The experiment was laid out in a Randomized complete block design with three replication (RCBD). Result revealed that nitrogen and irrigation influenced significantly on most of the growth, yield parameters and yield of blackgram. Plant height, number of branches per plant, number of leaves per plant, seeds per pod, leaf dry weight and stem dry weight increased significantly with 40 kg N ha-1 as basal with one irrigation at first flowering stage (35 DAS).This greater dry matter eventually supported the plant to produce more number of branches and pods per plant, which resulted in maximum seed yield per plant (10.45 g) or per hectare (1.86 ton). A functional positive relationship was observed among number of branches per plant, 1000-seed weight, pods per plant, and seeds per pod with seed yield.

Keywords: Integrated nitrogen, Irrigation management, Yield, Black Gram

Location: Sher-e-Bangla Agricultural University farm , Dhaka,

Start Date: 00-03-2006

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Black gram

Objectives:

1) To observe the optimum dose of nitrogen in black gram cultivation

2) To determine the irrigation level for the optimum yield of black gram

3) To determine the time of application of nitrogen fertilizer and irrigation in black gram for achieving maximum yield

Methodology:

Treatments of the experiment

The treatments were tested as follows:

T₁= No fertilizer and no irrigation (Control)

T₂ = 20 kg nitrogen/ha as basal without irrigation

T₃ = 20 kg nitrogen/ha as basal with one irrigation at first flowering stage

T₄ = 30 kg nitrogen/ha as basal without irrigation

T₅ = 30 kg nitrogen/ha as basal with one irrigation at first flowering stage

T ₆= 40 kg nitrogen/ha as basal without irrigation

T₇ = 40 kg nitrogen/ha as basal with one irrigation at first flowering stage

T₈ = 10 kg nitrogen/ha as basal and split 10 kg nitrogen/ha with one irrigation at first flowering stage

T₉= 15 kg nitrogen/ha as basal and split 15 kg nitrogen/ha with one irrigation at first flowering stage

T₁₀ = 20 kg nitrogen/ha as basal and split 20 kg nitrogen/ha with one irrigation at first flowering stage. The experiment was laid out in a Randomized complete block design with three replication (RCBD). Each replication had 10 unit plots in which the treatment combination were assigned at random. The size of each plot was 3m×2m. The blocks and unit plots were separated by 1.5m and 1m, respectively. The intra block and plot spaces were used as irrigation and drainage channels.The collected data were compiled and analyzed statistically using the analysis of variance (ANOVA) technique with the help of a computer package program MSTAT-C. The means were separated following least significance deference (LSD) test at 0.05 level of significance.
