Abstract

The crop biological yield refers to the total dry matter accumulation of a plant system. Improved harvest index of the represents increased physiological capacity to mobilize photosynthates and translocate them into organs having economic yield. The economic yield is a fraction of dry matter produced; the harvest index forms a useful measure of crop yield potential. Accordingly, multi agro-ecological field experiments were conducted for three consecutive seasons (2005/06, 2006/07 and 2007/08), to investigate the effect of five agro-ecological environments on the biological yield and harvest index of Faba bean (Vicia faba L.). The selection based on different soil types and different climatic growing conditions. Six Faba bean lines were used; namely: H.72/7/1, Daba.1/1, Z B F.1/1, C.86, Triple White and Turki. The treatments were arranged in a Randomized Complete Block Design (RCBD) with three replications. The results showed that the environments had significant effect on the biological yield. The highest biological yield of faba bean crop was obtained from the lower terrace soil, Riverian (Al Salama location). However, the high terrace soils in Almatara location attained the lowest biological yield compared to other environments. The highest harvest index of faba bean crop was observed in the middle and lower terrace soils in Hudeiba and Al Salama environment. In all production environments tested in this study the line C.86 scored the highest biological yield and harvest index.
