Abstract
Optimization of planting dates and plant density for maize cultivation for green fodder is of particular importance under increased aridity in the Republic of Crimea. The aim of the research was to identify optimum planting dates and plant density for maize hybrids for green fodder harvested at the late milk stage under rain-fed conditions of the steppe zone of the Crimea. In the course of the experiment, we found that for the period from 2016 to 2019 yield of green fodder depended on the hydrothermal conditions of the year and plant density, as well as we observed the interaction of planting dates and conditions of the year. The optimum plant density was 70 thousand plants per hectare. On average, the yield of green fodder of early-ripening maize hybrid ‘Nur’ was 19.58 t/ha; medium early hybrid ‘Mashuk 220 MV’ – 19.25 t/ha, medium ripening hybrid ‘Mashuk 355 MV’ – 21.3 t/ha.
