Abstract

A field experiment was undertaken at the Experimental Farm of Department of Agronomy of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur (H.P.) during kharif 2019 to study the effect of different tillage system and varieties on yield of rice. The treatments consisted of three rice varieties (viz., HPR 1156, HPR 2656 and HPR 2795) which were tested under three tillage systems viz., conventional tillage, and minimum tillage without residue and minimum tillage with residue treatment. The trial was laid out in split plot design with tillage system in main plot and rice varieties in sub plot and was replicated thrice. Conventional tillage recorded taller plants (124.50 cm) and higher dry matter accumulation (858.49 g/m-2) which was followed by minimum tillage without residue. Among the varieties tested HPR 2795 recorded taller plants (128.31 cm) and higher dry matter accumulation (891.33 g/m-2) which was followed by HPR 2656. Higher value of AGR, CGR and RGR was recorded in conventional tillage and among the varieties; HPR 2795 resulted in higher growth indices.
