Abstract

The field experiment was conducted during the year 2004-05 and 2005-06 at Main Experiment Station, Department of Horticulture, Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) to study the influence of organic manures, inorganic fertilizers and biofertilizers on leaf and soil nutrient status of papaya cv. CO-7. The maximum nutrient content of leaf viz., nitrogen, phosphorus, potassium, calcium and magnesium was recorded with T10 (FYM + 100% NPK + Azotobacter + PSB) which was at par with T11 (FYM + 100% NPK + Azospirillum + PSB), T4 and T5. However, the maximum nutrient status of soil i.e. nitrogen, phosphorus, potassium, calcium, magnesium, organic carbon and minimum pH, EC and ESP was noted with the application of T10(FYM + 100% NPK + Azotobacter + PSB) closely followed by T11(FYM + 100% NPK + Azospirillum + PSB), T4 and T5 during both the year of study. The improvement of soil health and nutrient status of leaves due to application of organic manures, inorganic manure and biofertilizers on papaya orchard.
