IMPACT OF BIO-ENHANCERS AND BIO-FERTILIZERS ON THE PRODUCTION ECONOMICS OF WINTER SEASON GUAVA

To assess the economic effects of bio-enhancers and bio-fertilizers on winter season guava production, an experiment was carried out in the Kalyanpur Nursery, Department of Fruit Science, Chandra Shekhar Azad University of Agricultural and Technology, Kanpur over two consecutive years, i.e. 2022-23 and 2023-24.Utilizing a randomized block design with ten treatments, each was replicated thrice.The findings clearly show that the combination of bio-enhancers and bio-fertilizers, as in treatment T 9 -FYM (10 kg tree -1 year -1 ) + Organic mulch (Paddy straw) + Panchagavya (3%) + PSB (50g tree -1 ) + Azotobacter (50g tree -1 ), achieved the highest Benefit: cost ratio (3.96) and net returns (Rs.352400.00hectare -1 ).The total fixed cost for cultivation was estimated at Rs. 71022.00hectare -1, with the maximum yield recorded in the same treatment (T 9 ) reaching 8.81 t hectare -1 .These results underscore the significant potential of using bio-enhancers and bio-fertilizers to enhance guava production by providing substantial economic benefits to the growers.
