Identification of the Effect of Sulfur Spray on Okra (AbelmoschusesculentusL. var. MI 5)Seedlings

Abstract

The study investigated that the effect of sulfur solutions as foliar spray with different concentrations on some selected growth parameters of ladies fingers plants. Pot experiment was conducted with six treatments (2g/L, 4g/L, 6g/L, 8g/L and 10g/L sulfur solutions) and three replicates. For each pot,two plants were maintained throughout the experiment. After seedling emerging, sulfur solutions were sprayed in every week using OSATU sprayer (5 L), until all the leaves got wet. After 30 days physiological features (Number of leaves, leaf length andleaf width) were recorded. Pest and disease incident also recorded at the mean time. Completely Randomized Design (CRD) with five replicates was used. Statistical analysis was performed with Duncan's multiple range test using SAS software (version 9.1.3). Result showed that the highest significant values in number of leaves (26), leaf length (21cm) and leaf width (24cm) were observed that in 10g/L solution of sulfur applied as foliar spray. With the increasing concentration of sulfur solutions the values for the selected physiological features also increased. Pest and disease incidence was significantly higher in control experiment while all the other treated plants don't showed any physiological damage or symptom. The results revealed that the application of sulfur as a foliar spray can be effectively use in increase the net photosynthetic area and to reduce the pest and disease incidence.
