Abstract:
The present studies were undertaken during 2013-14 and 2014-15 to investigate the influence of drip fertigation on yield and benefit cost ratio of cauliflower cv. PSBK-1. The field experiments were laid out in randomized block design with four replications and six fertigation levels (100, 90, 80, 70, 60 and 110 percent of recommended dose). Fertigation with recommended dose significantly, increased the curd weight and curd yield by 17.8 and 17.9 percent over 60% RD, and also this treatment had better water and nutrient utilization. Furthermore, fertigation applied in ten equal splits led to an optimum supply of nutrients to cauliflower at different growth stages thus leading to higher curd weight and yield. The highest benefit cost ratio (B:C) was recorded under 100 percent recommended dose (3.75:1) closely followed by 110 percent (3.56:1) while the lowest of 3.13:1 was recorded with 60% RD with the differences in benefits related to the higher marketable yield and nutrient availabilities. The study suggests that application of recommended dose of fertilizer through drip irrigation in 10 equal splits leads to higher and sustainable cauliflower production.
