The yield and quality of green of forage crops under irrigation conditions in the south of Ukraine
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 99, Issue
Abstract
The article considers the ways to increase the yield and improve the quality of old alfalfa green forage at the expense of winter crops (rye, wheat, barley, rape), early spring (barley, oats, rape, oil radish) and late-summer (Sudan grass and corn on green fodder) sowings and Mineral fertilizers. The research was carried out during 2015-2017 inthe dark chestnut soils of the RC "Radianska"of zemliaBilozerskyi district of Kherson region. Two backgrounds of mineral nutrition of plants: without fertilizers and N90P60 were studied. The minimum yield of green forage the experiment was provided by the sowings of early spring crops, the maximum –bythe sowings of late-summer crops. The use of compatible crops of alfalfa and the sown crops contributed to an increase in the yield of green forage by 21,48-29,99 t / ha or 53,1-82,3% in the variants of the experiment with winter crops, by 12,61-22 , 60 t / ha or 33.8-60.6% – in the variants with early spring crops and by 24.47-43.08 t / ha or 1.7-2.2 times – in the variants with late spring cropson average in the background of nutrition. The improvement of the nutrition background through the application of mineral fertilizers increased both the yield of green forage and the content of raw protein in it and its conditional yield per hectare of sowing. The weeds increased the yield of green forage, but significantly worsened its quality, the fertilizers, on the contrary, increased the yields and improved the quality of green forage, which met the requirements of feeding farm animals. According to the results of the three years research, it is determined that rye and rape are the most expedient for winter crops, while oil radish is forearly spring crops, and Sudan grass-for late spring. Cropsregardless of the time of sowing, it is recommended to improve the plant nutrition background, at the expense ot the application of mineral fertilizers.
