In 1978-1980 on light acid soil the effect of liming and mineral fertilization on yield and chemical composition of barley grain of Aramir and Diva varieties was investigated at the Experiment Station Zawady. Liming was applied at the rate of 1.5 t/ha of CaCO₃ and P - 26.2 and 34.9, K - 66.4 and 83.0 and N - 60, 80, 120 and 140 kg/ha. Liming led to a significant increase of the Diva variety yield,...
The objective of the study was to determine the changes in the chemical composition of winter rye during selected development stages as a result of mineral NPK, manure, keratin-bark-urea granulate, and sewage sludge fertilization. It was found that the content of elements under examination (P, K, Ca, and Mg) was significantly higher in the tillering phase, with the content of P significantly higher...
