Effect of organic manures and inorganic fertilizers on growth, yield and quality of Okra [Abelmochus esculentus (L.) Moench]

Abstract

An experiment was conducted to access the influence of organic manures and inorganic fertilizers on growth, yield and quality of Okra. Among 25 treatments under study, (FYM 3 t + SM 2 t + PM 0.5 t + VC 0.6 t + BF 7 kg + 60:30:30 N:P2O5:K2O kg ha-1 recorded maximum values for plant height (186.82 cm), number of nodes main stem (28.82), number of fruits plant-1 (28.93), fruit yield ha-1 (272.17 q), protein content (3.01%), Vitamin C content (17.59 mg 100-1g) and dry matter content (12.95%). Besides recording a minimum fiber content of 1.28%. PM 3 t + 60:30:30 N:P2O5:K2O kg ha-1 was next best treatment. Organic integration proved superior over sole applications but recorded lower values than 120:60:60 N:P2O5:K2O kg ha-1 . Treatment FYM 6 t + SM 4 t + PM 1 t + VC 1 t + BF 7kg ha-1 proved better, followed by PM 3 t + VC 3 t ha-1. Among sole applications of organics, T4 PM 6 t ha-1 proved better than rest of the organic sources.
