Abstract
A field experiment was conducted during Kharif 2019 at the Experimental Farm of the Department of Agronomy of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur (H.P.) to investigate the effect of different tillage systems and varieties on yield of rice. The treatments consist of three rice varieties (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 retention. The experiment was set up in a split plot design, with the tillage system in the main plot and rice cultivars in the sub plots, and it was triple replicated. The texture of the soil at the test site was silty clay loam in texture, acidic in reaction and in terms of nitrogen, phosphorus, and potassium, it was evaluated as medium. Significantly higher no. of panicles per meter square were observed in minimum tillage without residue though this treatment was at par with conventional tillage while significantly lower number of panicles m-2 were recorded with minimum tillage with residue retention. Significantly greater number of grains per panicle and panicle length were recorded in conventional tillage while minimum tillage with residue retention recorded lower values of number of grains per panicle and panicle length. Different tillage practices had no effect on the test weight of rice. Among different varieties tested, HPR 2656 recorded greater number of panicles per square meter which was at par with variety HPR 1156. Significantly higher number of grains per panicle and panicle length were recorded with HPR 2795 while the other two varieties were at par with each other. Rice variety HPR 1156 produced grains that had significantly greater test weight while the other two varieties (HPR 2795 and HPR 2656) were at par with each other with respect to this parameter. In terms of yield, conventional tillage produced much larger grain yield, straw yield, and biological yield and was at par with minimum tillage without residue. Among different varieties tested, HPR 2795 recorded much greater grain, straw and biological yields.
