Influence of Organic, Inorganic and Biofertilizers on Growth, Yield, Quality, and Economics of Okra [Abelmoschus esculentus (L). Moench] under Assam Condition

Abstract

A field experiment was conducted at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during March to July 2016 to study the “Influence of organic, inorganic and biofertilizers on growth, yield, quality and economics of okra”. The results indicated that application of RDF (T1) recorded the highest branches plant-1 (1.80), Leaves plant-1 (14.66), Leaf area index (1.36), Chlorophyll content of leaf (0.210 mg/g), Fruit length (14.62 cm), Fruit girth (4.64 cm), fruit weight (12.56 g), Fruit yield plant-1 (190.96 g) with the B:C ratio of 3.89 followed by followed by T2 [75% RD of NPK + Vermicompost @ 1 t ha-1 (mixed with microbial consortium)]. However, among the quality parameters the highest carbohydrate (6.98 g/100g) and the lowest fiber (14.30 %) content of fruit recorded in T3. It was found that with lesser fiber content the quality of okra fruit increased. The present investigation revealed that most of the growth, yield and yield attributes were found highest in treatment receiving RDF. Whereas superior value regarding the quality of fruit observed in the treatment receiving the combination of organic, inorganic and biofertilizers. Considering the adverse effect on soil health and environment it is not advisable to use chemical fertilizers at a higher quantity. A study led to the conclusion that good growth, yield with better quality of okra can be achieved by judicious application of organic, inorganic and biofertilizers
