Design and fabrication of seed sowing machine for zero till farming

Recent literature on no-till is revised with particular emphasis on research results. Increased interest in notill, as well as minimum or reduced tillage, is the result of changes in the economic circumstances of crop production, the opportunity to increase the area of more profitable autumn-sown crops and increased concern about environmental damage associated with soil inversion by ploughing .The relative costs of fuel and herbicides have changed appreciably in recent years making no-till more attractive commercially. While effective weed control is an essential aspect of no-till, current herbicide technology may not yet fully achieve this. Considering all these we have developed a seed sowing machine for no till farming by making a design change in seed sowing machine.
