 ABSTRACT

A field experiment was conducted, with a view to present study entitled “Effect of different levels of nitrogen and Novel organic liquid fertilizer on yield and quality of okra {Abelmoschus esculentus (L.) Moench} cv. GAO-5” during summer season 2017 at Agriculture Experimental Station (AES), Navsari Agricultural University, Village: Paria, Taluka: Pardi, District: Valsad, Gujarat, India. The experiment was laid out in Split Plot Design with comparing of two factors viz., different levels of nitrogen (100%, 80% and 60%) and Novel organic liquid fertilizer (0, 1 and 2%) with six replications. The result indicated that different nitrogen levels were significantly influenced the yield parameters of okra cv. GAO-5. Application of nitrogen @ 100 kg/ha was recorded significantly influenced the yield parameters like, days to 50% flowering (42.83 days), pod diameter (1.75 cm) days to 1st picking (48.11 days), number of pods per plant (15.93), pod length (11.36 cm), pod weight (11.18 g), pod yield per plant (0.148 kg/ha) and pod yield (10.93 t/ha). In case quality parameters like ascorbic acid (10.98 mg/100g) and fibre content (1.71%) were found significant superior in treatment N1 (100% RDN) while TSS and protein content were found non-significant. The foliar application of 2% Novel organic liquid fertilizer (L3) exhibited the significantly reduced to days to 50% flowering (41.02 days), days to 1st picking (47.33) consequently this treatment not only increased number of pods per plant (15.45), pod length (11.88 cm), pod weight (11.52 g), pod yield per plant (0.146 kg/ha) and pod yield (10.71 t/ha) but also produced favourable effect on pod quality in terms of ascorbic acid(11.00 mg/100g ) and fibre content (1.95%) in okra pods while in TSS and protein content was found on non-significant effect. From economics point of view, pod yield (11.52 t/ha) and highest benefit cost ratio (1.93:1) were obtained with treatment combination N1L3 i.e.100 % RDN with 2% of Novel organic liquid fertilizer. So, nitrogen fertilizer 100% RDN and 2% of Novel organic liquid fertilizer successfully increased yield (t/ha) and exhibited the highest B:C ratio of okra cv. GAO – 5 under south Gujarat condition.
