Abstract

Papaya (Carica papaya L.) is one of the most important and delicious fruit, but it is a heavy feeder of nutrients and requires judicious supplies of nutrients at frequent intervals for better growth and fruiting. Growers applied heavy dose of fertilizers without knowing the soil status, that leads to deterioration in the soil physical and chemical composition and also causes environmental pollution. Hence, it is imperative to shift from conventional nutrient management systems to integrated nutrient management systems for sustainable production as well as for maintaining the soil health. The present study 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 conditions. The INM helps restoring and sustain soil fertility along with crop productivity. Further, it also helps checking the emerging deficiency of nutrients other than N, P, K and favorably affects the physical, chemical, and biological environment of the soil.

Conclusion

In case of leaf nutrient content, significantly higher nutrient content were noted under the application of (T13) FYM + NPK (100%) + Azotobacter + PSB except or phosphorous content which was higher under (T14) FYM + NPK (100%) + Azospirillum + PSB during both years. Available nutrient status of soil, significantly higher values of available nutrients were reported under (T14) FYM + NPK (100%) + Azospirillum + PSB during the period of research. Overall, the appraisal study shows that the use of integrated nutrient management increases soil fertility, and improves soil health. If these treatments are continued for a few years, then minimise the use of inorganic fertilizers so farmers get more benefits.
