EFFECT OF PHOSPHORUS AND ZINC LEVELS ON YIELD AND SEED QUALITY OF MUNGBEAN VARIETIES

Abstract

An experiment was carried out at Sher-e-Bangla Agricultural University (SAU), Dhaka, Bangladesh during the period from March to June 2022 to study the effect of phosphorus and zinc levels on yield and seed quality of mungbean. Three varieties of mungbean viz., BARI Mung-6 (V 1 ), BARI Mung-7 (V 2 ) and Binamoog-8 (V 3 ) were combined with five P+Zn treatments viz., control treatment RDF+No P+Zn (F 0 ), 75% of RDF P+Zn (F 1 ), RDF of P+Zn (F 2 ), 125% of RDF P+Zn (F 3 ) and 150% of RDF P+Zn (F 4 ) laid out in Randomized Complete Block Design (RCBD) with three replications. Among different varieties of mungbean, V 3 (Binamoog-8) gave the best performance and showed maximum seed yield (1.46 t ha -1 ) and germination percentage (92.14%) compared to V 1 (BARI Mung-6) and V 2

(BARI Mung-7) varieties. Among the P+Zn treatments, F 4 (150% of P+Zn) showed the highest seed yield (1.51 t ha -1 ) and germination percentage (94.71%) compared to other treatments. Regarding, combined effected of variety and P+Zn treatments, the highest number of primary branches plant -1 (3.63), number of pods plant -1 (26.48), pod length (9.55 cm), number of seeds pods -1 (11.13), 1000 seed weight (51.42 g), grain yield (1.66 t ha ), stover yield (2.22 t ha -1 ) and germination percentage (95.81%) were recorded from the treatment combination of V 3 F 4 (Binamoog-8 + 150% of RDF P+Zn) whereas the lowest results were obtained from the treatment combination of V 2 F 0 . So, it may be concluded that the variety V 3 (Binamoog-8) combined with the treatment F 4 (150% of RDF P+Zn) was the best regarding growth, yield contributing parameters, seed yield and also quality parameters compared to other treatment combinations.
