The result indicated that different nitrogen levels were significantly influenced the growth parameters of okra cv. GAO-5. Application of nitrogen @ 100 kg/ha was recorded significantly maximum plant height (40.23, 82.98 and 92.32 cm) at 60, 90 DAS and at final harvest, maximum number of branches per plant at harvest stage (2.50) and total dry biomass (1297.85 g/plot). Soil parameters found non-significant like, available N, P2O5 and K2O. Results indicated that maximum nitrogen was found 250.95 kg/ha in treatment N1. Highest P2O5 and K2O was recorded 47.09 and 361.39 kg/ha. The foliar application of 2% novel organic liquid fertilizer (L3) exhibited the significantly maximum plant height (40.58, 81.81 and 89.42 cm) at 60, 90 DAS and at final harvest of crop, number of branches per plant (2.56) and total dry biomass (1287.67 g/plot) while in soil parameters i.e. available N, P2O5 and K2O were found non significant. Results indicated that maximum available N (248.22 kg/ha) and P2O5 (45.90 kg/ha) were recorded in treatment L3 and K2O was recorded (361.39 kg/ha) in treatment L1 (Control). Hence it can be concluded that 100% RDN and 2% novel organic liquid fertilizer (N1L3) successfully increased growth parameters exhibited the maximum net realization of okra cv. GAO – 5 under south Gujarat condition.
