The Effect of Conventional and Conservation Tillage Systems on Maize Yield

Absztrakt

Increasing the agricultural production is indispensable from the aspect of feeding the world’s population which can be provided with increasing amounts of irrigation water and mineral fertilisation. Increasing yields can be achieved with proper nutrient management, but yield safety can only be provided with proper water management. Today, producers can choose from various different maize hybrids. However, it is important to consider the nutrient response of the given hybrid and there is an increasing need for irrigation as a result of climate change. In Hungary, in addition to the conventional (ploughing-based) tillage technology of maize, moisture-saving and conservation (precision, strip-tillage) tillage methods also appeared. The principle of conservation tillage involves maintenance of surface soil cover through retention of crop residues achievable by practicing minimal mechanical soil disturbance. Strip-tillage is a form of conservation tillage systems. It combines the benefits of conventional clean tillage with the soil-protecting advantages of no-tillage systems. Strip-tillage has the potential advantages of providing a suitable seedbed for maize production and maintained yield level with minimum energy expenditures, while leaving surface residues in the inter-row area to reduce soil erosion, water loss from the soil and improved soil structure.
