W pracy wykorzystano dane agrometeorologiczne dotyczące: opadów, temperatury powietrza oraz usłonecznienia z 59 stacji meteorologicznych w Polsce z lat 1970-1995. Ponadto uwzględniono niedostateczne i nadmierne dekadowe stany uwilgotnienia gleby w okresie od kwietnia do lipca z Biuletynów Agrometeorologicznych IMGW, za lata 1966-1995, a także plony jęczmienia jarego z 49 województw zebrane z opracowań...
The objective of the studies was to determine the ratios of nitrogen to remaining macroelements (N/P, N/K, N/Ca, N/Mg, N/S i N/Cl) at the flowering state of spring wheat, spring barley and oat under the conditions of differentiated fertilization of very acid soil. The study showed the ratios of N/P, N/K, N/Ca, N/S in the tested plants were the broadest on the first (largest) level of fertilization...
On excellent wheat complex soil, research was done on the impact of north-south and east-west direction of seeding on yields and the kernel protein content in six varieties of spring corn. The direction of seeding did not have an essential influence on the kernel yield. A tendency to higher yields from nort-south seeding was discovered. This direction had a favorable impact on the protein yield, causing...
