| Abstract:
Experiments were laid out on 3 yrs-old plant of guava cv. Allahabad Safeda and maximum fruit number and yield (92 & 13.69 kg tree-1 and 283 & 40.11 kg tree-1) were recorded consistently for 2 years in the trees, applied with 20 kg FYM and inoculated with Azotobacter. Fruit quality parameters TSS (14.13°Brix) and vitamin C (242.40 mg 100 g-1 fruit) were improved with application of 20 kg FYM + BD-500. Leaf nutrients, N, P, K, Ca, S, Zn, Cu, Mn and Fe levels were found optimum with the application of different organic treatments. Improvement in microbial property of the soil was also improved after the application of different organic treatments. Bacterial count was maximum (5.1 x 106 cfu g-1soil) in rhizosphere soil with application of 20 kg FYM + ceilrich while yeast and mould was better (1.2 x 104) with FYM 20 kg + BD-500. | |
