Działanie azotu i magnezu na plonowanie, skład chemiczny nasion i niektóre cechy morfologiczne łubinów

A pot trial was carried out to investigate the effect of fertilization with nitrogen and magnesiu on the yield and morphological character of yellow lupine variety Teo and blue lupine variet Saturn and Polonez. It was found that nitrogen and magnesium fertilization decreased yield of yellow lupine see< Nitrogen fertilization increased yield of blue lupine seeds whereas magnesium fertilizati decreased it. The studied factors affected the differentiation of thousand seed weight, height plants and number of pods and seeds per plant. Concentration of macronutrients in lupine seeds was dependent only to slight degree on appli fertilization. Yield of crude protein depended first of all on genetic characters of varieties, yi< of crude fat was only slightly differentiated.
