Abstract:
Papaya (Carica papaya L.) is an important and economically valued fruit crop of the tropical and sub-tropical regions across the globe. It is believed to be a native to southern Mexico and adjoining Central America. It belongs to the family Caricaceae bearing chromosome no. 2n=18. Papaya is a good source of iron, Vit A, B and C. On the other hand the latex of papaya is a source of papain and chymopapain, has multifarious uses. Papaya is a heavy feeder of nutrients and requires judicious supply of nutrients at frequent intervals for better growth and fruiting. The application of heavy dose of fertilizers without knowing the soil status leads to deterioration in the soil physical and chemical compositions and also causes environmental pollution. Hence, it is imperative to shift from conventional nutrient management system to integrated nutrient management system for sustainable production as well as maintaining the soil health. The basic concept underlying the principal of INM is to maintain and improve soil fertility for sustaining the crop, use of all possible sources of nutrient and their scientific management for optimum growth, yield and quality of different crops in specific agro-ecological condition. The INM helps in restoring and sustaining soil fertility along with crop productivity. Further, it also helps in checking the emerging deficiency of nutrients other than N, P & K and favorably affects the physical, chemical and biological environment of soil.
