Abstract/ Executive Summary:

A pot experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during kharif II season of 2011 to investigate the growth, dry matter production and yield of mungbean genotypes under nutrient stress soil. Ten mungbean genotypes viz., IPSA-12, GK-27, IPSA-3, IPSA-5, ACC12890053, GK-63, ACC12890055, BARI Mung-6, BUmug- 4 and Bina moog- 5 and six nitrogen fertilizer levels viz., 0, 20, 40, 60, 80 and 100 kg N ha^-1 were included as experimental treatments. Results revealed that increasing nitrogen level in nutrient stress soil increased growth and dry matter production up to 60 kg N ha^-1 irrespective of genotype and thereafter decreased. Among the mungbean genotype IPSA 12 showed maximum leaf area, dry matter production and seed yield (14.22 g plant^-1) in nutrient stress soil. The lowest seed yield (7.33 g plant ^-1) was recorded in ACC12890053 under control condition.

Location: At Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur

Start Date: 00-08-2011

End Date: 00-11-2011

Program Area: Crop-Soil-Water Management

Commodity: Mungbean

Objectives:

To evaluate the effect of nitrogen levels on growth, dry matter production and yield of mungbean genotypes under nutrient stress condition.

Methodology:

The pot experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during kharif II (August to November) season of 2011 of AEZ 28. The experimental site was located at 24009 N latitude and 90026 E longitude and 8.4 m above the sea level which is characterized by subtropical climate. The soil was sandy loam having 6.9 pH, 0.538 % organic matter, 0.05%N, 0.16 mg kg^-1 P, 0.85 meq % K, and 0.70 mg kg^-1 and the Rhizobium count was 4.55 x 108 g soil. Each pot containing 12 kg soil was fertilized with 32 kg K ha^-1 in the form of muriate of potash and mixed thoroughly with soil.
The experiment was established in pot containing 12 kg soil collected from codda bazaar which belongs in codda series. Experimental soil was fertilized 25 kg P and 32 kg K ha^-1 in the form of triple super phosphate and muriate of potash, respectively and incorporated thoroughly into soil. The experiment was laid out in completely randomized design (CRD) with 4 replications. There were 10 genotypes like IPSA 12, GK 27, IPSA 3, IPSA 5, ACC12890055, GK 63, ACC12890053, BUmug 4, BARI Mung 6 and Bina moog 5 and six level of nitrogen 0, 20, 40, 60, 80 and 100 kg N ha^-1 as treatment variable and applied at 15 days after sowing.
Seeds were sown on 31 August, 2011. For uniform germination, a light irrigation was given immediately after sowing of seeds., the plants were thinned at first trifoliate stage and 4 plants was remained maintained for recorded growth parameter and one plants remained finally for seed yield in pot. All agronomic management and plant protection measures were kept uniform during the whole growing period of mungbean. Data on growth parameters, dry matter partitioning and yield were recorded. Leaf area were measured using automatic leaf area meter at 50% flowering stage.

Achievement/Findings:

The results revealed that nitrogen is necessary to ensure better growth and productivity of different mungbean genotypes under nutrient stress soil. But the genotype IPSA 12 performed better in nutrient stress soil where 60 kg N ha^-1 is optimum for better crop growth and development.
