Besides a very good protein fodder legumes can also leave a good stand for the forecrop. In effect of legumes symbiosis with bacteria they are able to fixed N2. Thanks to that their cultivation does not require high doses of nitrogen fertilizers, and fixed nitrogen is also available in the soil for the successive crop. The aim of researches was to recognize the impact of blue and yellow lupine forecrops...
Legume-cereal mixtures cover a considerable cultivated area in Poland what follows mainly from better and more stable yielding of mixed stands than pure ones. Besides a very good protein fodder the legume – cereal mixture can leave also good stand for subsequent plant. It is an effect of symbiosis of legumes with symbiotic bacteria and thanks to that lower doses of nitrogen are used in the mixture...
The aim of the present research was to proof the yielding role of nitrogen and sulfur in the process of growth and development of winter wheat. The experiment was conducted at a greenhouse, in Mitscherlich pots and soil had a low concentration of sulfur. Three increasing doses of N were applied in this experiment. The N sources were ammonium nitrate (without sulfur) and tetra urea calcium sulfate...
Pszenicę ozimą uprawiano w wazonach Mitscherlicha. Pierwszym czynnikiem doświadczenia był nawóz azotowy: saletra amonowa (bez S) i czteromocznikan siarczanu wapnia (zawierający S), a czynnikiem drugim - dawka azotu: 0,8, 1,6 i 2,4 g N·wazon-1. Rośliny zbierano w trzech fazach rozwojowych, oznaczano ich masę oraz wykonano analizy chemiczne na zawartość: N, P, K i S. Stwierdzono, że deficyt siarki spowodował...
