Comparison of Biophysical Parameters in D-DSR and TPR

Abstract

The study explained comparison of the biophysical parameters with in the two rice cultures. Study was conducted in the farmers field at Jogulamba Gadwal District of Telangana under same management practices. The biophysical parameters were recorded during the crop growth stages like Vegetative, Maximum Tillering, Panicle initiation, Flowering and Maturity. The data was analyzed by using the two-sample t test with equal variances reveled that there were no significant differences was observed in the dry matter produced, SPAD and LAI values of the two rice cultures at Vegetative, Maximum Tillering, Panicle initiation, Flowering and Maturity of the crop growth. The significant difference was found in the plant height at Maximum Tillering, Panicle initiation and Flowering. The total number of tillers were also significant at flowering Due to the pest infestation in the TPR reported the highest number of tillers when compared with D-DSR, the number of tillers at harvest were also less due to unproductive tillers damaged by pest in TPR than D-DSR.
