Effect of different tillage systems and cultivars on yield and yield attributes of rice (Oryza sativa L.)

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