Effect of time of sowing and plant spacing on broccoli production

Abstract

A field experiment was conducted at Agricultural Research Station, BARI, Thakurgaon during rabi season, 2009/10 to find out the optimum time of sowing and plant spacing on broccoli production. Three sowing time viz. (i) 1 October, (ii) 15 October and (iii) 30 October and three plant spacing viz. (i) 60 x 40cm, (ii) 60 x 50cm and (iii) 60 x 60cm were included in the study. Yield and yield contributing characters were significantly influenced by the treatments. 1 October sowing produced the highest yield (21.39 t/ha) and 30 October sowing produced the lowest yield (13.6t/ha) of broccoli. On the other hand, closer spacing (60 x 40cm) produced the highest yield (18.8t/ha) which was statistically similar to 60 x 50cm (17.6t/ha) and lowest yield (16t/ha) was obtained from 60 x 60 cm spacing. 1 October sowing and 60 x 40cm plant spacing combination produced the highest yield (22.5t/ha) which was statistically similar to 1 October sowing and 60 x 50cm plant spacing (21.9t/ha) and the lowest yield (12.8t/ha) was produced from 30 October sowing and 60 x 60cm plant spacing combination.
