Abstract

A field trial was carried out on an alluvial soil at Shandaweel, Up­per Egypt to evaluate the contribution of bulk density, total porosity, field capacity, OM and available-P in predicting chick-pea. yield, which re­ceived P-fertilizer, OM and gypsum. The results obtained revealed that all soil properties under study were affected positively by the added ma­terials. Field capacity is the direct variable to straw yield, while for seed yield bulk density and field capacity are responsible. Available-P and to­tal porosity are the accepted direct variables for content of protein in seeds.
