2. Avoid the use of synthetic chemical pesticides.Control weeds, pests and diseases were done by mechanical, biological, and crop rotation.

3. Avoid the use of growth regulators and synthetic chemical fertilizers. Soil fertility and productivity enhanced and maintained by adding crop residues, animal manure, and natural mineral rocks, and planting of legumes and crop rotations.
