YIELD AND ECONOMICS OF MUNGBEAN AS INFLUENCED BY ORGANIC AND INORGANIC FERTILIZER MANAGEMENT

Abstract

An experiment was carried out at Sher-e-Bangla Agricultural University Agronomy field, Dhaka to investigate the yield and economics of mungbean as influenced by organic and inorganic fertilizer management during the period from October to December, 2018. The experiment comprised 12 different treatments with organic and inorganic fertilizer and their combinations viz., F 1 = Recommended Dose of Fertilizer (NPKSZnB), F 2 = Vermicompost + 50% Recommended Dose of Fertilizer (NPKSZnB) , F 3 = Vermicompost + 75% Recommended Dose of Fertilizer (NPKSZnB), F 4 = Vermicompost , F 5 = Vermicompost + PK, F 6 = Vermicompost + NK, F 7 = Vermicompost + NPK, F 8 = Vermicompost + NP, F 9 = 50 % Vermicompost + 50 % Recommended Dose of Fertilizer ( NPKSZnB ), F 10 = Vermicompost + NPKB, F 11 = Vermicompost + B, F 12 = Control (no fertilizer). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The variety, BARI Mung-6 was used in this experiment as the test crop. Plant height, branches plant -1 , nodules plant -1 , pods plant -1 , pod length, seeds pod -1 , weight of 1000 seed, seed yield, stover yield, biological yield and harvest index, economics analysis were tested under different treatments. Results revealed that, F 3 treatment produced higher pod length (9.81 cm), number of pod plant -1 (9.53), number of seeds pod

(11.27), 1000- seed weight (71.90 g), seed yield (1.87 t ha -1 ), stover yield (3.14 t ha ), Biological yield (5.01 t ha -1 ). The treatments F 2 and F 9 also showed statistically similar results in respect of yield and yield contributing characters. The highest and comparable net returns was obtained with the application of vermicompost + 75% RDF (Tk. 90778 ha -1 ) followed by Recommended Dose of Fertilizer (Tk. 69359 ha ). The treatment influenced significantly on most of the growth, yield parameters of mungbean. Application of Vermicompost and 75% RDF (F 3 ) treatment could be the best fertilizer management for cultivation of mungbean for higher yield.
