PRODUCTIVITY INCREASE OF POTATO VARIETIES DUE TO WATER-SOLUBLE FERTILIZERS TERRAFLEKS APPLICATION
The effect of complex water-soluble fertilizers terrafleks on the productivity of different potato varieties was studied. At the background of 40 t/ha of manure the efficiency of foliar dressing by terrafleks increased for all investigated potato varieties according to the increasing basic mineral fertilizers rates. At the background of 40 t manure per ha + N120Р120К120 the productivity increased from 3,3 t/ha for middleearly varieties - to 4,8 t/ha for late varieties, at the background of 40 t manure per ha + N90Р90К90 - from 2,8 to 4 t/ha, at the background of 40 t manure per ha + N60Р60К60 - from 2,0 to 2,8 t/ha respectively.
