Abstract/ Executive Summary:

An experiment was conducted at Sher-e-Bangla Agricultural University farm during the period from February to April 2012 to study the effect of organic and inorganic fertilizers on growth and yield of mungbean (BARI Mung 5). The experiment was followed by Randomized Completely Block Design with three replications. During the experiment following treatments were incorporated T₀; Control, T₁; 10 tha^-1 Cowdung (Recommended dose), T₂; 10 tha^-1 Cowdung + 25 % of recommended dose of inorganic fertilizer, T₃; 10 tha^-1 Cowdung + 50 % of recommended dose of inorganic fertilizer, T₄; 10 tha^-1 + 75% of recommended dose of inorganic fertilizer, T₅; 10 tha^-1 Vermicompost (Recommended dose), T₆; 10 tha^-1 Vermicompost + 25% of recommended dose of inorganic fertilizer, T₇; 10 tha^-1 Vermicompost + 50 % of recommended dose of inorganic fertilizer, T₈; 10 tha^-1 Vermicompost + 75 % of recommended dose of inorganic fertilizer, T₉; 100 % Inorganic fertilizer. Maximum numbers of pods/plant (25.6), seeds/pod (12.1), seeds/plant (312.6), seed yield/plant (14.6 g), 1000-seed weight (35.6 g), seed yield (1127.5 kg/ha), N content in seeds (3.39%), P content in seeds (0.35%) and K content in seeds (2.25%) was found from T₈ treatment while lowest was found from T₀.

Keywords: Mungbean, fertilizers, yield and NPK content

Location: Sher-e-Bangla Agricultural University (SAU) farm, Dhaka

Start Date: 00-02-2012

End Date: 00-04-2012

Program Area: Crop-Soil-Water Management

Commodity: Mungbean

Objectives:

To study the effect of organic and inorganic fertilizers on growth and yield of mungbean (BARI Mung 5)

Methodology:

The experiment was carried out at the Sher-e-Bangla Agricultural University (SAU) farm, Dhaka to study the effect of organic and inorganic fertilizers on growth and yield of mungbean (BARI Mung 5) using Randomized Completely Block Design with three replications during the period from February to April of 2012. During the experiment, following treatments were incorporated: T₀; Control, T₁; 10 tha^-1 Cowdung (Recommended dose), T₂; 10 tha^-1 Cowdung + 25% of recommended dose of inorganic fertilizer, T₃; 10 tha^-1 Cowdung + 50 % of recommended dose of inorganic fertilizer, T₄; 10 tha^-1 + 75% of recommended dose of inorganic fertilizer, T₅; 10 tha^-1 Vermicompost (Recommended dose), T₆; 10 tha^-1 Vermicompost + 25% of recommended dose of inorganic fertilizer, T₇; 10 tha^-1 Vermicompost + 50 % of recommended dose of inorganic fertilizer, T₈; 10 tha^-1 Vermicompost + 75% of recommended dose of inorganic fertilizer, T₉; 100 % Inorganic fertilizer. Each plot was measured 3 m x 2 m. The lands were finally prepared on 17^th February 2012. Organic fertilizers (Cowdung and vermicompost) were applied along with urea, TSP, MoP, gypsum, zinc sulphate and boric acid as per treatments during the final land preparation. Healthy seeds of mungbean @ 35 kg ha^-1 were sown by hand as uniformly as possible in furrows with 30 cm line to line distance. Data was taken from ten randomly tagged plants. Data were taken at plant height, number of leaves/plant, number of branches/plant, days to 50% flowering, number of pods/plant, number of seeds/pod, number of seeds/plant, seed yield plant, 1000-seed weight, seed yield/ha, nitrogen content in seeds (%), phosphorus content in seeds (%), potassium content in seeds (%). The plant material (seed) were dried in an oven at 600 C at 72 hours after sun drying and finely ground in a grinder machine for chemical analysis. The total nitrogen was determined from the seed sample by macro Kjeldahl method. Phosphorus, potassium and sulphur were analyzed by following standard methods. Phosphorus in the digest was determined colorimetrically using SnCl₂ as reducing agent. The intensity of color read at 660 nm wave length with a spectrophotometer. Potassium of the plant sample was determined with the help of flame emission spectrophotometer. The samples were aspirated into a gas flame. The air pressure was fixed at 10 PSI. Percent emission was recorded. The collected data on different growth and yield parameters and nutrient contents of mungbean were statistically analyzed. The means for all treatments were calculated and the analyses of variances for all the characters were performed by ‘F’ variance test using MSTAT-C computer package program. The significance of difference between pair of means was performed by the Dancan’s Multiple Range Test (DMRT).

Achievement/Findings:

Combination of organic and inorganic fertilizer found to be more productive compared to sole use of inorganic fertilizers. This may be able to reduce the doses of inorganic fertilizers by combining the both. It is evident from the results that, in case of BARI Mung 5, Vermicompost @ 4 tha^-1 + 75 % of optimum dose of inorganic fertilizer gave statistically same yield with Cowdung @ 6 tha^-1 + 75% of optimum dose of inorganic fertilizer. So, if we use these combinations, it will allow us to reduce the use of 25% inorganic fertilizer at least.
