Abstracts |
A study was conducted to determine the effects of different organic manures and biofertilizers with or without chemical fertilizers combined on pear cv. Pant Pear-18. Treatments comprised: a control (600:400:400 g NPK/tree); 50 kg farmyard manure (FYM)/tree + 350:300:150 g NPK/tree; 50 kg FYM/tree + 37.5 g vesicular arbuscular mycorrhiza (VAM)/tree + 350:225:150 g NPK/tree; 10 kg poultry manure (PM) + 300:150:250 g NPK/tree; 2 kg neem cake (NC) + 500:380:376 g NPK/tree; 37.5 g VAM/tree + 600:325:400 g NPK/tree; 1.25 g Azotobacter/tree + 535:400:400 g NPK/tree; 1.25 g phosphate solubilizing bacteria (PSB)/tree + 600:335:400 g NPK/tree; and 25 kg FYM + 10 kg PM + 2 kg NC + 1.25 g Azotobacter + 1.25 g PSB/tree. Different treatment combinations using organic nutrition to reduce the quantity of recommended inorganic fertilizers had significant effects on yield and quality of Pant Pear-18. The treatment consisting of 10 kg PM + 300:150:250 g NPK/tree had the highest yield (50.17 and 62.50 kg, respectively) in both years and also recorded a significant improvement in fruit quality in terms of total soluble sugars, reducing sugars, nonreducing sugars, total sugars, fruit weight and volume. Treatment with 25 kg FYM + 10 kg PM + 2 kg NC + 1.25 g Azotobacter + 1.25 g PSB/tree enhanced fruit quality but had less effect on productivity.. |
