INFLUENCE OF PLANTING GEOMETRY ON GROWTH AND YIELD OF MUNGBEAN

Abstract

An experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka during March to June 2015 to study the effect of spacing on the growth, yield and yield attributes of three varieties of mungbean. The experiment comprised with two factors viz. (i) variety and (ii) spacing. Five spacing treatment (30 cm × 10 cm, 20 cm × 20 cm, 30 cm × 30 cm, 40cm × 40 cm, 50 cm × 50 cm) and three varieties (BARI mung 4, BARI mung 5, BARI mung 6) were used. There were fifteen treatment combinations under the study. Results showed that cultivar and spacing significantly influenced all the parameters studied. The mungbean variety BARI mung 6 stand superior than BARI mung 4 and BARI mung 5 in respect of plant height (8.11 cm, 17.86cm, 26.31cm, 48.737cm) , branches plant -1 1 (1.06 g, 7.68 g, 13.57g, 17.87g) , pods plant (2.14, 2.85, 3.68 ) , dry matter plant -1 (37.8), pod length (7.63 cm), length of pods, seed pod -1 (9.64), 1000 seed weight(44.208 g) , seed yield (0.515 tha -1 ) and stover yield (1.69 tha -1 ). The 20cm × 20 cm spacing was superior in terms of plant height( 8.59cm, 20.09cm, 30.57cm, 49.290cm), branches plant -1 ( 2.84, 4.15, 5.07 ), dry matter plant -1 (2.23g,13.15g, 17.02g, 22.77g), pods plant -1 (35.71), length of pod (9.03 cm), seed pod -1 (10.77), 1000 seed weight (45.72 g), seed yield (0.8989 tha -1 ) and stover yield (2.19 tha ). In interaction, the variety BARI mung 6 in combination with 20 cm × 20 cm spacing produced maximum yield (1.16 tha -1 ) as well as yield attributes. This treatment showed 77.8% higher seed yield than control.
