W doświadczeniu wazonowym, które założono na piasku gliniastym lekkim z gryką odmiany Hruszowska, na tle stałego nawożenia azotem, fosforem i potasem zastosowano wzrastające dawki magnezu: 0,00; 0,25; 0,50 oraz 1,00 g Mg/wazon. Rośliny opryskiwano roztworem syntetycznej cytokininy (benzylo- aminopuryna - BAP) o stężeniu 45 mg/dm3, który sporządzono na bazie acetonu z dodatkiem Tween-80 jako emulgatora...
W trzyletnim doświadczeniu polowym z bobikiem odmiany Dino na tle jednakowego nawożenia fosforem (60 kg P205 • ha-1) i azotem (40 kg N • ha-1) zastosowano zwiększane nawożenie potasem (0-210 kg K2O • ha-1). W roślinach (nasiona, strączyny i łodygi) oznaczono zawartość podstawowych makro- pierwiastków, a w glebie - przyswajalnych i wymiennych składników pokarmowych. Stosowanie zwiększanych dawek nawozu...
A pot experiment was conducted to study the effects of increasing rates of nitrogen, potassium, sodium and magnesium on yield and mineral composition of rescuegrass (Bromus unioloides Humb. et Kunth.). The highest yield of dry matter was obtained in the case of nitrogen and potassium treatments, while the effect of sodium and magnesium turned aut tobesmall. Increasing rates of nitrogen improved mineral...
In the six-year field experiment on the weakly loamy sand the increasing (from 0 to 800 tons per hectare) rates of hard coal fly ash were appplied. The ash treatments were used in the four experimental series e.i. without organic substance, manure, cereal straw and tree bark. Increasing ash rates have increased magnesium contestations in crops as in the soil. However, the utilization of this nutrient...
