Effectiveness of urea with urease inhibitor -utec to the potato

In the he article are presented the research result on effectiveness of application new form of urea on potato. New urea form is urea with urease inhibitors. This fertilities type allow to reduce losses of nitrogen in ammonium form. Field experiment was carried out in 2017 on solonetc light chestnut soils with heavy granulometric compound in the conditions of the Volgograd region In the experimental polygon of the lower Volga agricultural research Institute - branch of Federal state budgetary scientific institution "Federal scientific center for agro-ecology, integrated land reclamation and protective afforestation wounds". As an obect of research used potatoes mid-early table varieties Nevsky. The advantage of a new fertilizer form is the yield increase and improvement of tubers quality. Urea UTEC application leads to formation bigger and uniform tuber size. The use of urea UTEC provide the potato yield of 56.4 t/ha, with marketable tubers fraction up to 54.82 t/ha, the total yield increase to the control - 35...
