Response of Fertigation to crops

Significant savings in the use of fertilizers and increase in yield of various crops have been reported by researchers (Table 6) (Anonymous, 2001) (Patel and Rajput, 2001a, 2001b, and 2002). The research conducted at various places on fertigation indicated that crop yields were substantially increased from 26-40% in pomegranate, 11-41% in straw berry and 8 - 31% in grape.

Potential of fertigation

Studies revealed significant fertilizer savings of 20-60% and 8-41% increase in yields of horticulture and vegetable crops. Fertigation could be adopted for increased yield and fertilizer saving. It is the essence of drip irrigation. Fertigation is a must in order to realize the full potential and benefits of drip irrigation system. With increasing area under drip irrigation in India, there is tremendous opportunity of using fertilizer through fertigation system for many crops.
