The object of research - Reaction of corn hybrids of different groups of ripeness to methods of the basic soil tillage and level of the mineral nutrition. The purpose - to establish the features of formation of grain productivity of corn hybrids of different groups of ripeness depending on methods of the basic soil tillage and level of the mineral nutrition in the conditions of a southeast part of Steppe of Ukraine. The methods: field, laboratory, statistical, calculated - comparative. The results: elements of cultivation technology of corn hybrids are optimized which provide increase of grain productivity in the conditions of the southeast part of Steppe of Ukraine. The industrial check is conducted in farms of the Pologovs’ky district, the Zaporizhzha region, namely: in the limited liability company "Agrofirm the Batkivshchina" on 72 hectares and in the limited liability company «Agrofirm the Aurora» - on the area of 45 hectares.The novelty - for the first time in the conditions of the southeast part of Steppe of Ukraine the features of formation of grain productivity of corn hybrids at ploughing, different-depth, subsurface and zero soil tillage are established; possibility of increase of efficiency of the mineral nutrition at the expense of optimization of terms and methods of fertilizers application of and ratio in their structure of nitrogen, phosphorus and potassium is established; reaction of corn hybrids of different groups of ripeness to methods of the basic soil tillage and level of the mineral nutrition is revealed.The branch - agriculture.
