Response of okra seed production to bio-fertilizers

An experiment was conducted during rainy season of 2013–14, 2014–15 and 2015–16 at Vegetable Research Station, Kalyanpur of C.S. Azad University of Agriculture & Technology, Kanpur. The soil of experimental field was sandy loam with low fertility. There were seven treatments comprised recommended dose of NPK, Azospirillum + recommended dose of NPK, Azospirillum + 75% N + recommended doses of P&K, Azospirillum + 50% N + recommended doses of P&K, PSB + recommended dose of NPK, PSB + 75% P + recommended doses of N&K and PSB + 50%P + recommended doses of N&K. The treatments were evaluated i.e. growth, yield contributing characters and seed yield of okra. The okra variety Azad Bhindi-1 was sown with recommended agronomical practices. The highest seed yield of okra by 15.69 q/ha was reaped from Azospirillum + recommended dose of NPK, followed by PSB + recommended dose of NPK (14.57 q/ha). The growth and yield contributing characters were concordant to the seed yield.
