Effect of different machinery system on plant growth and yield of wheat under combine harvested paddy field

Abstract

Evaluation of different wheat sowing technologies under paddy residue conditions were conducted in a combine harvested paddy field. Wheat variety (GW 366) was sown with different farm machines viz., T1: Happy seeder, T2: Rotavator with zero till drill, T3: Disc harrow+zero till drill, T4: Trichoderma application + Disc harrow with zero till drill zero and T5: Mulcher + zero till drill in combine harvested paddy fields. All the rice straw was remained in the field itself but spreaded uniformly manually/stubble shaver, In case of happy seeder both the operation is cutting of paddy and sowing of wheat accomplished in one operation. In T2: Rotavator + Zero till drill is loose paddy straw and stubble are incorporate in the soil with the help of rotavator, In T3 Disc harrow + Zero till drill loose paddy straw and stubble are incorporate the soil, In T4: Trichoderma application + Disc harrow + zero till drill, application of Trichoderma help to easily decomposition of paddy straw incorporated in the soil. In T5: Mulcher with zero till drill are cut the stubbles and loose paddy straw spared then sowing the wheat. In Among the treatments, T2 gave better result over the rest of the treatment. The grain yield was maximum in treatment T2 (2454.4 kg/ha).
