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 harvested paddy field. Field of paddy variety PR-121 was harvested with combine. The straw load was 8.22 t/ha at moisture content of 20.2 per cent. Wheat variety (HD 2967) was sown with different farm machines viz., T 1 : Happy seeder, T 2 : Spatially modified no till drill and T 3 : Roto till drill in combine harvested paddy fields. In T 1 , all the paddy straw was remained in the field itself but spreaded uniformly manually/stubble shaver, in T 2 , 40 per cent of loose paddy straw removed manually/chopping of paddy straw with paddy straw chopper cum spreader while in T 3 , there was a partial collection of loose paddy straw manually for better operation of the machines. The grain yield was maximum in treatment T 2 (5395.9 kg/ha).
