Effect of Organic Nutrition Practices on Papaya (cv. Surya) Fruit Yield, Quality and Soil Health
A field experiment was conducted during 2005-07 at Indian Institute of Horticultural Research, Bangalore, on papaya cv. Surya with six organic treatments along with recommended dose of fertilizers and no manure/fertilizer application. Results indicated that crop growth and fruit yield were higher in inorganic fertilizer treatment (55 t ha1) compared to organic treatments (26.9 to 38 t ha-1). There was no significant variation in average fruit weight and TSS, but shelf life of the fruit was significantly higher in organic treatments (6.2 to 7.9 days) as compared to inorganic fertilizer treatment (5.1days). Among the treatments, application of 7 kg urban compost plant-1 or 10 kg FYM plant-1 was found to be ideal for improving soil health in terms of microbial population, and biochemical reaction compared to other treatments.
