Abstract

Micronutrient disorder appears to be the most widespread and frequent problem in crop production worldwide, resulting in severe losses in yield and nutritional values. To overcome this problem study was conducted. The experiment was conducted in kharif during 2020 and 2021 in Factorial RBD with three replications and fourteen treatment combinations comprising two varieties i.e., V1: GAO 5 and V2: GO 6 and seven level of foliar application of Zn and Fe viz., M1: FeSO4 @ 0.50 %, M2: ZnSO4 @ 0.50 %, M3: Fe EDDHA @ 0.1 %, M4: Fe EDDHA @ 0.2 %, M5: Zn EDTA @ 0.1 %, M6: Zn EDTA @ 0.2 % and M7: Control (Water spray). Which were sprayed in four frequencies at 30, 40, 50 and 60 DAS. Variety GAO 5 recorded the maximum pods per plant (20.50), pod yield (258.89 g/plant and 13.91 t/ha), fibre content of pod (2.56%), chlorophyll content of pod (0.496 mg/100 g), phenol content of pod (0.112%), and the lowest amount of leaf membrane damage (32.72%). Foliar application of Zn EDTA @ 0.2% resulted in maximum days to last picking (96.93), number of pods per plant (21.35), pod weight (14.43 g), pod yield (269,44 g/plant and 14.64 t/ha), fibre content of pod (2.62%), chlorophyll content of pod (0.504 mg/100 g), phenol content of pod (0.119 %) and least amount of leaf membrane injury (26.92 %). Zn EDTA applied topically at 0.2% with variety GAO 5 produced the maximum pods per plant (24.22), with the highest chlorophyll content (0.509 mg/100 g).

Conclusion

From the two years of field study, it can be concluded that variety GAO 5 found better with regards to yield and quality parameters and foliar application of Zn EDTA @ 0.2 % at 30, 40, 50 and 60 days after sowing improves yield parameters as well as quality of okra pods. Combining the effects of variety GAO 5 and foliar Zn EDTA @ 0.2% spray increases okra pod length, number of pods per plant, and chlorophyll content of pod.
