Abstract

The agricultural residue mostly paddy residue is primarily regarded as a waste owing to its minimum utilization and discarding relating problems. Indian agriculture is progressively succeeding, more emphasizes is provided on the crop yield and productivity. But in existing situation, the management of bulk amount of post-harvest agricultural residue is cumbersome and onerous task and requires more momentum for its effective incorporation and utilization. With these implications, the farmers frequently compelled to opt for appropriate option of burning residues inopen farm field for getting good riddance from large quantity of paddy straw. To discourse these concerns, the in-situ post-harvest residue management machinery can prove to be a feasible alternative which not only provides judicious paddy straw management but also can restricts open field burning. These machineries are either based on the in-field retention or incorporation of crop residues. Recently developed machines viz., Happy seeder, Super seeder, Mulcher etc. plays an indispensable role in replenishing soil quality and reducing environmental pollution calumniating from stubble burning. These technologies supports in modifying soil physical properties, improving soil organic content and edaphic factors, provides economy to farmers, saving energy and consequently eradicating indiscriminate residue burning. The paper reviews the transformation and evolution in functional design and development of the paddy straw management machineries. It focuses on the previous developed technologies in the field straw management and its associated problems and issues
