Essay

Research object: cabbage crops effect on water and physical properties, as well as on agrochemical characteristics of soil fertility and yields of the following crop - winter wheat. Research objective: the main objective of the thesis is to make a comparative evaluation of differently fertilised cabbage crops as winter wheat forecrops when they are harvested for green mass, green manure and seeds. Research methods: a multi-factor, short- time field experiment, laboratory methods corresponding to conventional agricultural practices. Research results. Theory: it's the first time that the most efficient cabbage crop as a winter wheat forecrop on dark chestnut soils under irrigation has been specified, and the mineral fertilisers dosage to ensure high grain yields has been determined. Practice: spring rape seed production as a winter wheat forecrop allows getting wheat grain yields of about 70 c/ha as well as achieving total economic efficiency of growing winter wheat and spring rape at 2482 hryvnas per hectare. Application sphere: Irrigated lands of Southern Ukraine.
