Technologia uprawy i plonowanie pszenżyta ozimego w środkowowschodniej Polsce

Abstract

The work presents data collected by means of a survey carried out in the years 1998 and 2006 – in central-eastern Poland. There was observed an increase in the share of cereals in the structure of planted crops to the level of 82.4% the increase for triticale being 27.3%. A large share of cereals in rotations deteriorated the value of the land and reduced winter triticale yields. The yields were very low (on average 3.59–3.78 t · ha–1). However, in both years they were higher than the averages for Poland, which was a result of higher (than the average for Poland) mineral fertilization applied to the land. Winter triticale yields were mainly influenced by mineral fertilization, pesticides and soil quality. Higher yields were obtained on farms where higher fertilization was applied, pesticide applications were more frequent and triticale was cultivated on higher-quality soils.
