Impact of Phytoremediated Sewage Water and Organic Inputs on the Growth and Yield of Okra

Abstract

Okra belongs to family Malvaceae, it is a good source of nutrition as well as for farmer economy. This experiment was based on two years field work. During the year 2021-22 and 2022-23 it was aimed to study the Effect of phytoremediated sewage water irrigation, organic manures & biofertilizers on growth and yield of okra var. Kashi chaman in Prayagraj agro climatic condition. The experiment was designed as Randomized block design consist of 16 treatments and 3 replicates of each. Among which the treatment T15 with the combination of Azotobacter @4 kg/ha + PSB(Pseudomonas) @2 kg/ha +Vermicompost + treated sewage water, emerged as most effective in promoting highest Number of branches (4.61) number of leaves (28.52) leaf area LAI (124.12 cm2) Root length per plant (15.15 cm) maximum fruit yield (464.72 g) was found significant at 0.05 level of critical difference. Whereas maximum plant height (127.11 cm) was recorded in T9 (Vermicompost+ Azotobacter @4 kg/ha and TSW). So it can be concluded that this treatment combination can enhance plant growth and yield attributes of okra variety Kashi chaman along with sustaining nutrient levels in the soil. Ultimately, by applying these practices it offers an alternative way for resource-limited farmers to achieve long-term productivity.
