摘要：Nowadays conventional farming practices are not sustainable and produce harmful effects on the environment. In many developing countries, environmental degradation is mainly takes the form of nutrient depletion and reduces the potential of food production. Challenges demand that the issues of efficient use of resources and adoption of resource conservation technologies (RCTs). Cropping system which enhance the maintenance of a permanent soil cover, minimum disturbance of soil, diversification of crop species, improvement of biodiversity and enhance natural biological processes above and below the soil is known as conservation agriculture. Conservation agriculture has four principles: 1) minimizing mechanical soil disturbance and seeding directly into untilled soil improve soil organic matter content and soil health; 2) enhancing soil organic matter using cover crops and crop residues. This protects the soil surface, conserves water and nutrients, promotes soil biological activity; 3) diversification of crops in associations, sequences and rotations to enhance system resilience that complement reduces tillage and reduce retention by breaking cycles of pests and diseases; 4) controlled traffic that loosen soil compaction. These RCTs are in the form of reduced tillage, residue management, laser land levelling and site specific nutrient management etc. These technological components also plays an important role to decrease the greenhouse gases by decreasing the use of fossil fuels. There is a need to adopt these new technologies under diversified cropping system and appear to be appealing options to achieve sustainable and intensive crop production under different agro-ecological environments. Now, a move from conventional to conservation farming system is highly warranted to maintain the ecological balance for future generation.
