Water management imperatives in zero/reduced till

摘要: Resource conservation as means of enhancing resource use efficiency assumes high priority for sustainable agriculture. Resource conservation technologies (RCTs) such as zero/reduced tillage, surface seeding and raised bed sowing are emerging as new paradigm shift for enhancing conservation of soil, water, nutrient and energy. The long-term sustainability of zero/reduced tillage under crop residue or bare fields without residue is now a subject of attention. Judicious use and management of water is imperative in zero tillage to improve productivity of land and water. It would be imperative to examine and study the impact of RCTs in water conservation and adopt water management practices to supplement better adoption of RCTs/ZT to improve not only water use efficiency but also overall input use efficiency and water productivity. The paper covers impact of zero-tillage on water use aspects based on our …
