Abstract
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 object 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 – 35.6%, in monetary terms this amounted to 245887.0 RUB/ha additional profit. Under these conditions, was obtained lowest amount of non-marketable yield – 0.16 t/ha, which is 2.65 times less than in the control variant. The advantage of urea UTEC application in comparison with ammonium nitrate was the increase in the yield of marketable potatoes by 5.1 t/ha and an additional profit up to 76.8 thousand rubles/ha. The Assessment of the potato quality showed that the best treatment was also the treatment with UTEC urea, the starch content in tubers was 9.22%. Note that almost the same value of the indicator in the variant with the use of urea (option 2), and the lowest starch content was noted when using ammonium nitrate – 9.05%.
