Ecological and legal problems of protection of lands

Abstract

The purpose. To determine the optimum scheme of sowing and density of plants of parsnip in conditions of Right-bank Forest-steppe for deriving high productivity of standard root crops. Methods. Field —for research of elements of technique of growing and weather environment on the object of researches; biochemical — for determination of quality of root crops; statistical — for verification of reliability of the gained data. Results. Results are brought of researches (2015-2017) on study of effect of schemes of sowing and density of plants of parsnip (Pastinaca sativa L.) of the grade Stimulant on productivity, marketability and biochemical content of root crops in conditions of Right-bank Forest-steppe. Conclusions. It is fixed that optimum schemes for growing parsnip are as follows: (70+10+10)×8, (70+10+10)×10, and (50+20) ×8 cm. The highest yield of commodity root crops was gained at sowing on rows (90-93%). Reduction of area of feed leads to increase of amount of plants at a unit of area and to decrease of average mass of root crop. At increase of feeding area the average mass of root crop is also increased.
