Abstract: The present investigation Impact of organic fertilizers on performance of strawberry cv. Sweet Charlie under sub-tropical conditions of Punjab was carried out in the experimental plot of Department of Horticulture, Khalsa College, Amritsar during the year 2018. The investigation was laid out in RBD (Randomized Block Design) with eleven treatments replicated thrice. In the trial strawberry plants were fertilized with different organic (vermicompost and biofertilizers as azotobacter & PSB) and inorganic fertilizers to find out the optimum doses of these fertilizers to increase the growth and yield of the fruits. The results of the present study showed that vermicompost 2.80 t/ha + biofertilizers(T1) was found to be the best in improving the vegetative growth of the plants resulting in maximum plant height (15.05 cm), number of leaves per plant (23.24), average leaf area (90.87 cm2), number of flowers (26.03), fruits (19.05) per plant and fruit set (75.96 %) followed by treatment T2 (vermicompost 2.80 t/ha). The fruits yielded from the plants fertilized with vermicompost 2.80 t/ha + biofertilizers registered maximum fruit length (3.52 cm), breadth (2.36 cm) and fruit weight (14.58 g). The application of vermicompost 2.80 t/ha + biofertilizers also resulted in maximum fruit yield (298.44 g) per plant and (477.50 q) per hectare respectively.
