Effect of Drip Fertigation Levels on Soil Fertility and Productivity of Cauliflower cv. Pusa Snowball K-1

The field experiment were conducted during 2013-14 and 2014-15 to study the effect of drip fertigation on nutrient availability, plant parameters yield cauliflower. experiments laid out in randomized block design with four replications six levels (60, 70, 80, 90, 100 110 per cent recommended dose). Recommended doses N, P K are 125, 108 76kg/ha, respectively for cauliflower Himachal Pradesh. Fertigation dose fertilizer resulted highest available N (365.3 kg ha-1), (95.8 ha-1) (477.8 ha-1). Drip also increased Zn, Cu, Fe Mn content by 8, 29, 21 40 cent, over 60% (i.e N- 75, 65 46 kg/ha) treatment. productivity was maximum application percent nutrients through irrigation recorded an increase 17.9 curd 60 RD suggests that 10 splits leads higher sustainable production.
