Standardisation of fertigation in papaya for higher productivity and profitability

A field experiment conducted to standardize the fertigation in papaya (Carica L.) variety Arka Prabhat with 12 treatments split plot design, indicated that 75% recommended fertilizers (250:250:500 g NPK/plant/year) through water soluble recorded significantly higher fruit yield (47.34 t/ha), fertilizer use efficiency (20.45 kg yield/kg of nutrient applied) and increase 31% over soil application. The TSS was although not influenced by both doses sources fertigation, lower cavity index (3.12%) observed when RDF supplied organics soil. Fertigation 100% organic carbon (1.16%). However, inorganic found more economical gross returns (Rs.7.10 lakh/ha), net (Rs.4.7 lakh/ha) benefit cost ratio (2.96)
