Physiological analysis of the effects of different soils on sugar beet crops in different years.
Abstract
In each of three years, sugar beet was grown on; seven different soils with two rates of fertilizer-N. Differences in yield between different soils and seasons were associated principally with differences jn leaf area index (L). These were associated with differences in N supply, but also depended on water supply. Net assimilation rate (E) varied less than L, and E was smaller where yield and L were greater.
