Abstract/ Executive Summary:

An experiment was conducted at the Field Laboratory, Bangladesh Institute of Nuclear Agriculture, Mymensingh during February to May 2010 to investigate the effect of biofertilizer and urea on growth, yield attributes and yield of two mungbean varieties. The experiment comprised of four fertilizer combinations viz., (i) control (No biofertilizer and urea, F₀), (ii) Biofertilizer with no urea (F₁), (iii) Biofertilizer with 1/3rd urea (13 kg urea ha^-1) of recommended dose (F₂), (iv) Recommended dose of urea (40 kg urea ha^-1) with no biofertilizer (F₃) and two varieties viz., BINAmung-5 and BINAmung-6. The recommended doses of TSP, MoP and gypsum were applied in each plot. The experiment was laid out in two factors randomized complete block design with three replications. Results showed that combined application of urea and biofertilizer was more effective in plant growth and yield attributes than single application of biofertilizer or urea. Among the fertilizer combinations, biofertilizer with recommended TSP, MP, gypsum and 1/3rd urea showed superiority in plant height, number of branches plant^-1, leaf area plant^-1, number of nodules plant^-1, chlorophyll content in leaves, total dry mass plant^-1, absolute growth rate, number of pods plant^-1 and harvest index compared to other fertilizer treatments which resulted the highest seed yield both per plant and per hectare. In contrast, the lowest above parameters was recorded in F₀ where biofertilizer and urea was not applied. The genotypic variation existed in morphological, growth, yield attributes and yield with BINAmung-5 was superior to BINAmung-6. The combined effects of variety and fertilizer combination on yield attributes and yield were superior in F₂ (biofertilizer with 1/3rd urea of recommended dose) of both the genotypes with magnitude was higher in BINAmung-5 than in BINAmung-6. Therefore, biofertilizer with 13 kg urea ha^-1 may be recommended for increased seed yield of mungbean after few more field trials under different AEZ of Bangladesh.

Program Area: Crop-Soil-Water Management

Commodity: Mungbean

Objectives:

1. To assess the effect of biofertilizer along with different levels of nitrogenous fertilizer on growth and yield of mungbean varieties.

Methodology:

A field experiment was carried out at the field laboratory of Bangladesh Institute of Nuclear Agriculture, Mymensingh (24075? N and 90050? E), Bangladesh, during February to June 2010. The soil of the experiment was sandy loam having a total nitrogen 0.06%, organic matter 1.05%, available phosphorus 18.5 ppm, exchangeable potassium 0.28 meq%, sulphur 18 ppm and pH 6.8. The experiment comprised of four fertilizer combinations viz., (i) control (No biofertilizer and urea, F₀), (ii) Biofertilizer with no urea (F₁), (iii) Biofertilizer with 1/3rd urea (13 kg urea ha^-1) of recommended dose (F₂), (iv) Recommended dose of urea (40 kg urea ha^-1) with no biofertilizer (F₃) and two varieties viz., BINAmung-5 and BINAmung-6. The experiment was laid out in two factors randomized complete block design with three replications. The recommended doses of TSP, MoP and gypsum were applied in each plot. Total amount of urea, TSP, MP and gypsum were applied at basal doses during final land preparation. The size of the unit plot was 2.5 m x 3.0 m. All the fertilizers were incorporated into the soil before sowing of seeds. In case of biofertilizer, seeds of mungbean varieties were inoculated with Rhizobium inoculants just before sowing. The seeds were kept in polythene bags and were mixed with molasses for adhering to the biofertilizer. Then the biofertilizer was mixed thoroughly with the seeds and were kept in shade and cool place to avoid sticking together. The seeds were sown in furrows on 17 March 2010 and furrows were covered by soils soon after seeding. The line to line and plant to plant distances were maintained at 30 cm and 10 cm, respectively. To obtain data on growth characteristics, a total of two harvests were made: the first one at reproductive stage (flowering and fruiting stage at 35 days after sowing, DAS) and the second one at fruiting stage (50 DAS). Five plants from each plot were randomly selected and uprooted for obtaining data of necessary parameters. The plants were separated into leaves, stems and roots and the corresponding dry weights were recorded after oven dry at 80 ± 2⁰C for 72 hours. The leaf area of each sample was measured by LICOR automatic leaf area meter (LI 2000 USA). The growth analyses like absolute growth rate and relative growth rate were carried out. Nodule was counted at 50 DAS. Chlorophyll was determined at 50 DAS. Other morphological and yield attributes were recorded at harvest. Pods were harvested three times. Harvests were completed by 28 May 2010. Finally, seed weights were taken on individual plot basis at moisture content of about 12% and converted into kg ha-1. Harvest index was calculated by dividing economic yield to biological yield of plot by multiplying with 100 and expressed in percentage. The collected data were analyzed statistically using the computer package programme, MSTAT-C and the mean differences were adjudged by Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

It may be said that single application of biofertilizer or urea or in combination of biofertilizer and urea as basal dose enhance plant growth and development which resulted increase seed yield in mungbean. Among the fertilizer combinations, biofertilizer with 1/3 urea (13 kg urea ha^-1) of recommended dose had superiority in plant growth, yield components and yield over other fertilizer combinations. Therefore, biofertilizers with 13 kg urea ha^-1 may be recommended for increase seed yield of mungbean after few more field trials under different AEZ of Bangladesh.
