Abstract/ Executive Summary:

A field experiment was conducted at Regional Agricultural Research Station, Jumalpur during 2003 to determine the requirement of boron and molybdenum for the cultivation of mungbean. Both boron and molybdenum were applied @ 1 and 2 kg/ha from boric acid and sodium molybdate, respectively. Yield and yield components significantly responded to different treatments and on an average, the combined application of B and Mo was superior to their single application. The treatment comprising 2 kg B/ha with 1 kg Mo/ha increased seed yield by 96.63%, over recommended fertilizer dose N, P, K and S. The net return was highest in the treatment having 2 kg B with 1 kg Mo/ha.

Keywords: Mungbean, Boron, Molybdenum, Recommended fertilizer

Location: Regional Agricultural Research Station, Jamalpur

Start Date: 00-00-2003

End Date: 00-00-2003

Program Area: Crop-Soil-Water Management

Commodity: Mungbean

Objectives:

To determine the requirement of boron and molybdenum for the cultivation of mungbean.

Methodology:

The experiment was conducted at Regional Agricultural Research Station, Jamalpur during the Kharif-l of 2003. The experimental field was located at 24°56'N latitude and 89°55'E longitudeat a height of 19m above the sea level. Before conducting the experiment, soil sample representing Sonatala soil series was collected from the field of Regional Agricultural Research Station, Jarnalpur, Bangladesh under Old Brahmaputra Flood Plain Soil (AEZ 9) and analyzed in the laboratory. The soil was characteristically acidic (pH 6.0) having organic matter of 1.62%. total N 0.09%, exchangeable K 0.08 me/100g soil, exchangeable Ca 1.3 me/100g soil, exchangeable Mg 1.87 me/100g soil, available P 4.9 ppm, available S 7.69 ppm, available Zn 0.68 ppm, available B 0.14 ppm. The experiment was laid out in a randomised complete block design replicated three times. The micronutrients, such as Band Mo each @ 1 and 2 kg/ha along with recommended fertilizers (20, 18, 25 and 10 kg/ha of N, P, K and S) and a control (without ferti lizer) were taken into consideration to constitute ten treatments. All the plots received recommended fertilizers except the control. The source of NPKSB and Mo was urea, TSP, MP, gypsum, boric acid and sodium molybdate were applied as per treatments. The unit plot was 4m x 5m. The variety was BARI Mung-5 and seeds were sown in rows 30 cm x 5 cm spacing on the 20 February and harvested on 15 May 2003. Agronomic practices and plant protection measures were taken whenever necessary. Ten plants were randomly uprooted from each plot after 59 days of sowing for recording data on nodules/plant and nodules dry wt/plant. At maturity, data were recorded for plant height, plant/m2, branches/plant, pods/plant, seeds/pod, 1000-seed weight and yield was also recorded. Ten plants were collected prior to harvest from each plot to collect data on yield attributes. Data on grain yield was recorded from 6m2 area. Collected data were analyzed statistically and the means were separated following Duncuns Multiple Range Test (DMRT). The partial budget and marginal analysis of cost of undorninated fertilizer treatments were done. The analysis was done considering the prices of the nutrients, products and additional costs only.

Achievement/Findings:

From the study it may be concluded that in addition to recommended fertilizers, 1 kg Mo/ha in combination with 1 or 2 kg B/ha may be applied in mungbean for attaining higher yield and net returns.
