Abstract
A field study was conducted during kharif, 2021 at Regional Agricultural Research Station, Warangal to evaluate the performance of rice varieties under different systems of cultivation for central Telangana zone. The treatment consisted of three systems of cultivation i.e., transplanted rice system with 15x10 cm spacing, wet direct seeded rice (Drum seeding) with 30x6-8 cm spacing and dry direct seeded rice at 30 cm row spacing in main plots and four varieties i.e., RNR 15048 (Telangana sona), WGL 44 (Siddi), WGL 915 (Warangal Rice-1) and KNM 118 (Kunaran sannalu) in sub plots. Experimental data revealed that transplanted rice recorded significantly superior growth components and yield attributing characters i.e., number of tillers m-², number of effective tillers m-², dry matter production, grain yield, straw yield and harvest index (%) compared to other systems of cultivation. Significant higher grain and straw yield was recorded with transplanted rice system followed by wet DSR and least in dry DSR. Under varieties KNM 118 registered higher dry matter production, grain yield, straw yield and harvest index (%) as compared to remaining varieties.
