EFFECT OF NUMBER OF SEEDLINGS PER HILL AND SPACING ON GROWTH AND YIELD OF TRANSPLANTED AMAN RICE

Abstract

A field experiment was conducted with a view to examining the effect of number of seedlings hill-1 and spacing of planting on the growth and yield of transplanted aman rice (var. Ranisalute). The experiment consisted of five different number of seedlings hill-1 viz. 2, 3, 4, 5 and 6 and three plant spacing viz. 50 cm × 50 cm, 40 cm × 40 cm and 30 cm × 30 cm. The experiment was laid out in a factorial randomized complete block design with three replications. Individually number of seedlings hill-1 and spacing had no significant effect on growth and yield components. Numerically the highest grain yield and harvest index was obtained from 6 seedlings hill-1 and of 30 cm × 30 cm spacing separately. There were significant variation in the interaction effect of seedling hill-1 with spacing on the yield components except panicle length and 1000-grain weight. Among the interactions 3 seedlings hill-1 with 30 cm × 30 cm spacing produced the highest grain yield and harvest index, the uppermost straw yield and biological yield was obtained from 2 seedlings with 30 cm × 30 cm spacing and maximum grain panicle-1 was produced by 2 seedlings with 40 cm × 40 cm spacing.
