Impact of organic and bio-fertilizer combinations on the growth and yield of okra (Abelmoschus esculentus (L.) Moench)

The present study was performed between March and June 2023 to study the effects of organic and bio-fertilizer combinations on the growth and yield of Okra (Abelmoschus esculentus L. Moench). Four nutrient combinations included T0 (Control), T1 [Jaivik Prom (100 kg/ac) + 4ml Bio NPK], T2 [Pori Potash (100 kg/ac + 4ml Bio NPK], T3 [Dharti ka Chaukidar (10 kg/ac) + 4ml Bio NPK] and T4 [Jaivik Poshak (7 kg/ac) + 4ml Bio NPK] were analyzed in this study using a randomized complete block design (RCBD). Pearson's correlation coefficient was calculated to determine the strength and direction of linear relationships among the parameters and a heat map was generated to represent these correlations visually. The effects of organic nutritional treatments were analyzed in terms of plant growth and yield parameters. All the combinations of organic and bio-fertilizers except T1 (Jaivik Prom + Bio NPK) exhibited a positive impact on plant height, leaf area, number and yield of fruits. Similarly, the combination of Bio NPK with Pori Potash + Bio NPK (T2) and Dharti ka Chaukidar + Bio NPK (T3) was also found fruitful in promoting the growth and yield of okra. These results concluded that organic nutrients in combination with bio-fertilizers can enhance the growth and yield of vegetable crops including okra.
