abstract
The present study was conducted at Horticulture Research Farm, Department of Horticulture Chaudhary Charan Singh University Campus, Meerut, during summer season of 2022 to investigate the effect of organic manures and bio-fertilizer on growth and yield performance of okra. The study performed in randomized block design and replicated three times. The treatments involved in the study were nine in number i.e. T1 (control), T2 (FYM @ 20 t/ha), T3 (FYM @ 20 t/ha + Azotobacter), T4 (FYM @ 20 t/ha + Azospirillum), T5 (Vermicompost @ 4 t/ha), T6 (Vermicompost @ 4 t/ha + Azotobacter), T7 (Vermicompost @ 4 t/ha + Azospirillum), T8 (FYM @ 10 t/ha + Vermicompost @ 2 t/ha + Azotobacter), and T9 (FYM @ 10 t/ha + Vermicompost @ 2 t/ha + Azospirillum). All treatments were randomly distributed among the plots. All variable parameters related to growth and yield attributes were significantly influenced by different treatments of organic manures and biofertilizers. Results revealed that among all the treatments, the soil application of FYM @ 10 t/ha + Vermicompost @ 2 t/ha + Azospirillum (T9) gave the better effect on vegetative and yield parameters viz. plant height (87.26 cm), number of branches per plant (3.33), number of leaves (20.00), leaf width (15.80 cm), days to 50% flowering (39.33), number of fruit per plant (14.46), fruit length (14.11cm), fruit diameter (10.26 mm), weight of fruit (12.60 g) and fruit yield (121.89 q/ha). While the treatment T1 (control) showed minimum values in term of growth and yield of okra.
