Урожайність сучасних гібридів кукурудзи залежно від застосування засобів захисту рослин та регулятору росту

Abstract

Generalized 2-year data (2009-2010) researches on the studies of the reac- tion of corn hybrids on application of the growth regulator and means of plant protection have shown, that the greatest increase of the seed processing produc- tivity by Vial ТТ fungicides and Taboo insecticides is marked at hybrid of Credit МV average ripeness on the background of the limited application of fertilizers (humus 30 t/ha + N30P30K30) – 0.71 t/ha. Under the experience on the reaction studies of the Varta МV hybrid of early average ripeness on application of the growth regulator of the Gumata of potassium plants the greatest increase of productivity of grain is received on the background of the full dose of fertilizers (humus 30 t/ha + N60P60K60) + processing of the seeds + spraying of the crop in a phase 3-5 sheets – 0.80 t/hа
