At the two driest sites, Tel Hadya and Brida, the recharge front did not extend beyond 9I and 75 cm, respectively (Figs. IC, D, E, F) and thus the rooting depth of the crop was greatly restricted compared witli Jindiress. Thus at these sites there was little difference between treatments in the root distribution of the crop, even between winter and spring sowing. This is ilustrated in Table 5a which presents the "extractable" moisture within discrete depth intervals under all treatments. "Extractable" moisture is defined as the difference between the maximum moisture content observed in any soil horizon and that at maturity. The ability of a crop to extract moisture from a given depth interval will depend largely upon the root proliferation with that depth interval, and thus "extractable" moisture values will reflect the root distribution. It can be seen from Table 5 that at Tel Hadya and Brida there was no meaningful difference between treatments. The difference between sites represent the different soil moisture charateristics of the two soils. The same picture holds true at Jindiress when comparing the three wintersown crops, but a contrasting picture emerges when comparing winter sowing with spring sowing. Table 4 indicates that the recharge front under spring-sown 149
