%X This paper investigated the effect of pre\|sowing irrigation and phosphorus fertilizer supply on grain yield formation. Four treatments were employed: CK was as a control, P was phosphorus fertilizer applied in cultivated soil layer, W was pre\|sowing irrigation with 30 mm water depth, WP was W plus P. Soil moisture, root and shoot biomass, and grain yield were measured in the given periods. The root biomass and its distribution in medium and down soil layers in WP treatment were higher than others. Compar...
