Abstract
Experiments were laid out on 3 yrs-old plant of guava cv. Allahabad Safeda
and maximum fruit number and yield (92 & 13.69 kgtree-1 and 283 & 40.11 kgtree-1)
were recorded consistently for 2 years in the trees, applied with 20kg FYM and
inoculated with Azotobacter. Fruit quality parameters TSS (14.13°
Brix) and vitamin
C (242.40mg100g-1 fruit) were improved with application of 20kg 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 (5.1x106
cfu g-1soil) in rhizosphere soil with
application of 20 kg FYM + ceilrich while yeast and mould was better (1.2x104
) with
FYM 20kg+BD-500.
