The influence of method and application time of retardant CCC and herbicide fluroxypyr on weed control degree and wheat yielding was examined under field condition during 2006–2008. CCC and fluroxypyr were used separately and in tank mixture at two growth stages: BBCH 31–31 and BBCH 35–37. Both products were applied in recommended doses: CCC – 2.0 l/ha and fluroxypyr – 0.8 l/ha. The selectivity and...
В период 1977-1980 гг. сравнивали влияние разного числа растений мака полевого (О, 1-5, 5-10, 11-25, 26-50 на 1 м² ) на урожай озимой пшеницы и его структуру. Исследовательский материал составляли 120 образцов Колосов отобранных с площади 1 м² интенсивных сортов (Грана, Люна) и средне-интенсивных сортов (Мироновская 808) пшеницы возделываемой на рендзине в центрально-восточном макрорайоне Польши....
