Effect of Integrated Nutrient Management on Growth, Yield And quality of Okra (Abelmoschus esculentus (L.) Moench)

A field experiment was carried out at Vegetable Research Farm, Department of Horticulture (Vegetable and Floriculture), Bihar Agricultural University, Sabour during Kharif season of 2017 to study the integrated effect of bio-inoculants, organic and chemical fertilizers on growth, yield and economics of okra. The sixteen integrated treatments consisting chemical, organic and biofertilizers were arranged in a randomized block design replicated thrice. Results revealed that the application of 75 % RDN through chemical fertilizer + 25 % N through vermicompost + Azotobacter @ 20 g kg-1 of seed+ PSB @ 20 g kg-1 of seed (T14) influenced most of the characteristics significantly and recorded the highest values of plant height, number of branches per plant, fruit length, average fruit weight, number of fruits per plant, yield per hectare and B: C ratio (1.62) except number of nodes to first flower appearance, days taken to 50 % flowering and days to first picking, which were the minimum under same treatment (T14). The quality parameters viz. the ascorbic acid, TSS and crude protein content in fruit were also highest in T14 treatment. Thus it can be inferred that 25% of RDN can only be substituted through Vermicompost along with the use of biofertilizers (Azotobacter + PSB)
