Effect of Organic Manure and Biofertilizers on the Growth, Yield and Productivity of Guava under Meadow Orcharding Karanveer Devi Singh C.John Wesley

The study was conducted to investigate the effect of organic manure and biofertilizers on the growth, yield and productivity of guava under meadow orcharding at Horticulture Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj. In this experiment, various organic sources (Farm yard manure (30 kg/plant/y), vermicompost (30 kg/plant/y) and neem cake (3 kg/plant/y) along with various biofertilizer combinations (Azotobacter, Azospirillum, PSB) were tested on five-year-old guava cultivar 'Allahabad Safeda' to study its effect on growth, fruiting and yield. The results obtained showed higher fruit weight (218.00 g), fruit length (7.60 cm), fruit diameter (7.42 cm), maximum number of fruits produced per plant (26.64 fruits/plant), maximum yield per plant of 5.81 kg/plant and maximum yield per ha (23.12 t/ha) with the application of T9. The highest total soluble solids (12°Brix) and total sugar content of fruit (8.26%) with the application of T9. Application of nutrients through organic along with biofertilizers improve soil health in terms of mean microbial population in the rhizosphere of root zone soil as compared to control. From the present study, the application of biofertilizers with the combination of organic manures has a beneficial effect on the availability of major nutrients in the soil to help in maintaining of the soil fertility and plant growth of the fruits at a desired level. It can be concluded that, for better growth, yield and quality guava fruits, the guava trees should be fertilized with (FYM (30kg/plant) +Azospirillum @250g/tree +PSB @250g/tree +Neem cake @3kg/tree) per year with treatment T9.
