Evaluation of wheat sowing technologies under paddy residue conditions

Abstract

Evaluation of different wheat sowing technologies under paddy residue conditions were conducted in a combine\rharvested paddy field. Field of paddy variety PR-121 was harvested with combine. The straw load was 8.22 t/ha at moisture\rcontent of 20.2 per cent. Wheat variety (HD 2967) was sown with different farm machines viz., T1: Happy seeder, T2: Spatially\rmodified no till drill and T3: Roto till drill in combine harvested paddy fields. In T1, all the paddy straw was remained in the field\ritself but spreaded uniformly manually/stubble shaver, in T2, 40 per cent of loose paddy straw removed manually/chopping of\rpaddy straw with paddy straw chopper cum spreader while in T3, there was a partial collection of loose paddy straw manually for\rbetter operation of the machines. The grain yield was maximum in treatment T2 (5395.9 kg/ha).
