Abstract
The research was carried out at Fruit research station, Sangareddy, Hyderabad during the period of June, 2019 to January, 2020 (Mrig bahar crop) to know the effect of biofertilizers and biostimulant on yield parameters of guava (Psidium guajava L.) cv. Allahabad Safeda under meadow planting system. The study indicated that interaction between biofertilizers and biostimulant significantly influenced yield parameters. Among the twelve treatment combinations application of B3S3- Azotobacter @ 50 g tree-1 + Phosphate solubilizing bacteria @ 50 g tree-1 + Seaweed extract @ 75 g tree-1 recorded maximum fruit set (56.68 %), fruit retention (54.95 %), fruit length (7.12 cm), fruit diameter (7.14 cm), fruit weight (180.69 g) and yield per tree (4.51 kg).
Keywords: Guava, azotobacter, phosphate solubilizing bacteria, seaweed extract, yield parameters
