Zero tillage and water productivity: A review

Abstract

Nevertheless, zero tillage is the best choice because crop residues retained in zero tillage decreases evaporation, controls soil temperature, reduces erosion, reduces total cultivation costs, increases soil organic carbon stock, enhances water use efficiency and increases crop yield on sustainable crops. A range of resource management technologies are advocated to increase water productivity. In all agro-climatic conditions, the conservation of soil moisture is a crucial priority for improving soil and water productivity. Conserved soil moisture helps minimise water inputs without impacting grain yields, which further increases the output of water and crops. The best choice for efficient water usage and sustainable output could be zero tillage after maintaining sufficient residue load and with proper control of weeds. Keeping all of these under consideration, an attempt was made to come up with an efficient sustainable solution that could be used to implement the zero tillage successfully.
