Effect of different fertilizer levels and plant densities on agromorphological characteristics and yield attributes of hybrid and synthetic cauliflower

Field experiments were carried out to ascertain the effect of different levels of fertilizers and plant densities on agro-morphological characteristics and yield attributes of hybrid and synthetic cauliflower during 2005-06 and 2006-07 at the Bihar Agricultural College, Sabour, Bhagalpur, Bihar taking variety Pusa Hybrid-2 and Pusa Synthetic. The variety Pusa Hybrid-2 was found to be superior over Pusa Synthetic in terms of the curd diameter, net curd weight, marketable curds weight and total calculated marketable yield per hectare. All the growth parameters increased significantly with successive increments in the doses of fertilizers (NPK) levels only up to F3-N160 P120 K100 level. Further increase in fertilizer dose did not bring about significant increase in growth characters. Closer spacing S3 (60 x 30 cm) recorded significantly higher plant height and stem length of crop than wider spacing viz. S2 (60 x 45 cm) and S1 (60 x 60 cm). Wider spacing S1 (60 x 60 cm) produced significantly higher biological yield (gross plant weight), curd diameter, curd depth, net curd weight and marketable curd weight over closer spacing.
