Effect of Different Treatment Combinations on Yield and Yield Attributes of Okra (Abelmoschus esculentus L. Moench)

The present experiment was carried out during the Kharif 2010 at Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh. The experiment was laid out in the factorial randomized block design with four replications and nine treatment combinations, considering three levels each of zinc (0, 25 and 50 kg ZnSO₄ ha⁻¹) and iron (0, 25 and 50 kg FeSO₄ ha⁻¹). The results of experiment indicated that, among different levels of ZnSO₄ (0, 25 and 50 kg ha⁻¹), 50 kg ZnSO₄ ha⁻¹ significantly increased plant height (88 cm), number of leaves (14) per plant, immature green fruit girth (6.09 cm), immature green fruit yield (2888 kg ha⁻¹), dry pod yield (664 kg ha⁻¹), stalk yield (2215 kg ha⁻¹) and protein content (22.93 %) at harvest. Among different levels of FeSO₄ (0, 25 and 50 kg ha⁻¹), application of 50 kg FeSO₄ ha⁻¹ significantly increased number of leaves (14) per plant, immature green fruit girth (6.00 cm), immature green fruit yield (2934 kg ha⁻¹), dry pod yield (675 kg ha⁻¹), stalk yield (2204 kg ha⁻¹) and protein content (23.14 %) at harvest of okra.
