Effect of Different Inorganic Fertlizers and Bio Fertilizers on Growth, Yield and Quality of Okra (Abelmoschus esculentus L. Moench )

Abstract

This study was carried out during March – June 2022 on vegetable research farm Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj. The objective of the experiment was to screen out the best combination of biofertilizer and inorganic manures for growth, yield, and quality of okra and to work out the economics. The design of the experiment was randomized block design (RBD) with three replications. The result shows that T8  75%N + 100%PK + Azotobacter + Azospirillum + PSB was found superior in terms of plant height (9.30cm in 20 days, 30.23cm in 40 days, 43.58cm in 60 days),  plant spread (19.94cm2 in 20 days, 34.64 cm2  in 40 days, 60.74 cm2  in 60 days), days to first flowering (33.98 days), days to 50% flowering (42.43days), days to fruit setting (46.95 days), days to first fruit picking (48.68 days), fruit weight (9.83g), length of fruit at marketable stage (13.10cm), girth of fruit (2.02cm), no. of fruit per plant (23.98/plant), no. of seeds per fruit (48.39), fruit yield per plant(g) 235.65g, fruit yield per plot (kg) 7.78kg, fruit yield (t/ha) 19.44, TSS (14.61oBrix), ascorbic acid (21.31 mg/100g). Net economic returns of treatment were highest in T8 (75%N + 100%PK + Azotobacter + Azospirillum + PSB) Rs.472592.83 with highest cost benefit ratio of (4.27).
