Impact of Organic Fertilizers on Guava (Psidium guajava L.) Yield

The study was conducted at horticulture farm, Aroma College, Haridwar during summer season of 2022-23 to evaluate the performance of different organic source of nutrients on growth of Thai guava cv. VNR bihi. Therefore, biofertilizers were applied as per various treatments under the tree canopy. This experiment was designed in Randomized Block Design with three replicates. The highest fruit length (10.08 cm), Fruit breadth (12.90 cm), Average fruit weight (616.30 g), Number of fruits per plant (35), Yield (21.60 kg/plant), Number of seeds per fruit (287.00) to were found in T12 (Farmyard Manure + Poultry manure + Azotobacter + Phosphate Solubilizing Bacteria) From March to December every month followed by T11 ( FYM + Poultry manure + PSB).The lowest of all these parameters were found in control T14 (8.77 cm, 9.97 cm, 524.02 g, 25. Number of fruits/plant, 13.28 kg/plant, 225.25 Number of seeds/ fruit) was recorded.
