Abstract

The present experiment was carried out during theKharif 2010 at Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh. The experiment was laid out with four replications and nine treatment combinations, considering three levels each of zinc (0, 25 and 50 kg ZnSO₄ha^-1) and iron (0, 25 and 50 kg FeSO₄ha^-1). The results of experiment indicated that, application of ZnSO₄ @ 50 kg ha^-1 significantly increased plant height, number of leaves per plant, immature green fruit girth, immature green fruit yield, dry pod yield, stalk yield and protein content at harvest. Among different levels of iron application of 50 kg FeSO₄ ha^-1 significantly increased number of leaves per plant, immature green fruit girth, immature green fruit yield, dry pod yield, stalk yield and protein content at harvest of okra.

Keywords

Abstract

Seventy three surface (0-15 cm) soil samples from the three talukas viz., kutiyana, Ranavav and Porbandar of Porbandar district were collected from the cultivated fields and were analyzed for different chemical poperties. The results revealed that Na⁺ and Cl^- were dominant among the water soluble ions, whereas, Ca⁺⁺ and Mg⁺⁺ were dominant among the exchangeable cations. Nearly half (48.0%) of the cultivated coastal soils of Porbandar district were found normal in nature, followed by sodic (20.5%), saline (16.4%) and saline-sodic (15.1%).

Abstract

Seventy three surface (0-15 cm) soil samples were collected from the cultivated soils of Porbandar district, and were analyzed for EC and pH from saturation extract and 1:2.5 soil water ratios. The results revealed highly significant correlations between ECe and EC_2.5 and between pHs and pH_2.5. High correlation coefficient (r) and regression coefficient (b), high percentage of variance (R²) in case of EC_2.5 and pH_2.5 were observed and hence, prediction of ECe from EC_2.5 and pHs from pH_2.5 with greater precision was possible by using the regression equation for the soils of Porbandar district.

Keywords
