Урожайність та зимостійкість рослин ячменю озимого залежно від мінеральних добрив

Abstract

Досліджено вплив доз та співвідношення мінеральних добрив на ріст, розвиток рослин, зокрема під час вегетації, та на врожайність ячменю озимого. З’ясовано, як впливають мінеральні добрива на зимостійкість культури. Визначено оптимальні комбінації добрив, що забезпечують максимальну стійкість рослин до несприятливих умов зимового періоду. Встановлено, як впливають мінеральні добрива на ріст та розвиток. One of the leading agricultural cultures of Ukraine there is a winter barley. He has high potential of the productivity, besides a barley ripens winter-annual before winter wheat and barley furious accordingly on 8 and 12 days. It enables to free the field, properly to prepare soil and use an area under the repeated sowing. It is known that barley the winter-annual well reacts on bringing of mineral fertilizers. However next to advantages has the substantial failing – low resistance to cold. There were the directed niches exactly on the decision of this problem.Influence of doses and correlation of mineral fertilizers is investigational on growth, development and productivity of winter barley of-annual. It is found out how mineral fertilizers influence on resistance to cold of culture. Certainly optimum combinations of fertilizers which provide maximal firmness of plants to the not favourable terms of winter period. It is set, as mineral fertilizers influence on growth and development of plants during a vegetation. The most high resistance to cold of plants of winter barley-annual is got due to bringing of mineral fertilizers under the preseed cultivating in the doses of P30K30 and N30P90K60. The maximal productivity of plant of winter barley-annual is formed at bringing of mineral fertilizers in the dose of N60P90K30. Also the considerable productivity is got at the doses of N30P60K60 and N30P60K30 under basic till of soil.
