    The effect of nitrogen fertilization on the dry matter formation and the energy accumulation by spinach plants

  • Original language description

    In the years 1998 and 1999 in four periods (spring, first half of summer, second half of summer, autumn) was grown spinach, variety Pavana F1, in micro-plot trials in neutral soil (pH > 6,5) and in acid soil (pH < 4,5). The spinach pertain to the plantswith low net energy contents in dry matter of leaves. We measured this physiological value dur-ing vegetative period by calorimeter Laget MS 10 A and the contents of energy was from 11,52 kJ net energy to 15,61 kJ net energy in 1 g of dry matter of spinach leaves. The graduated rates of nitrogen fertilization (50 and 100 kg N.ha-1) increased the energy contents as many as 2,39 kJ.g-1 of dry matter compared with control variant without nitrogen fertilizer. The total formation of dry matter during vegetative period, spinach yield and the total accumulation of net energy by spinach plants were higher in neutral soil than in acid soil. The total quantity of produced dry matter and the total accumu-lated energy by spinach plants increased by
