    SOIL TECHNOLOGY vol. 3, p. 183-198 Cremlingen 1990 ] PEA PLANTING UNDER A LIMITED WATER SUPPLY ~ M.Y. Tayel, S.I. Abdel Rahman, Cairo M.A. Matyn, Gent Summary A field experiment was conducted on peas, grown in a sandy soil located in the Western Desert of Egypt, to find out the best management under a limited supply of irrigation water. The experiment was designed in such a way that the main, sub-main and sub-sub-main plots were subjected to the following treatments: ir- rigation treatments (66.2 and 77.8% of the IRn), conditioners (control, 10 m3/ha stable manure, 10 m3/ha stable manure + 56 kg/ha P205 + 200 kg/ha agricul- tural sulphur, 10 m3/ha stable manure + 75 g/m 2 bituminous emulsion, and 75 g/m 2 bituminous emulsion) and seeding rates (60, 70 and 80 kg/ha), respectively. Concerning the yield, water use effi- ciency and root distribution, the best results were achieved using 66.2% of the IRn throughout the growing season, 75 g bitumen/m 2 and a seeding density of 70 kg/ha. 1 Introduction Our food demands are tremendous and continuously increasing. To meet those demands, Egyptian agriculture is forced to expand in sandy soils under severe ISSN 0933-3630 @1990 by CATENA VERLAG, D-3302 Cremlingen-Destedt, W. Germany 0933-3630/90/5011851/US$ 2.00 + 0.25 constraints ...i.e. limited irrigation wa- ter resources, inadequate soil water re- tention and low soil fertility. The key to a successful sandy soil reclamation program, depends upon our ability to correctly integrate soil and water man- agement practices with the local environ- mental conditions. TAYEL et al. (1988) mentioned that mulching sandy soil with bituminous emulsion up to 75 g/m 2 had no signif- icant effect on seed index, water use ef- ficiency and yield of broad bean. Ac- cording to WAHBA et al. (1989), the treatment mentioned above, had no sig- nificant effect on height, stem diameter, and disk diameter of sunflower plant. On the other hand, MATYN et al. (1989), stated that bitumen mulch had a positive effect on individual garlic plant weight. TAYEL et al. (1989) and TAYEL & MATYN (1990) found that bitumen mulch at the rate of 75 g/m2 had a pos- itive effect on groundnut growth. They added that this effect varied with irriga- tion level, the mulched area, and heaping process. In general, water use efficiency is mainly affected by irrigation level. Many workers using different plants stated that water use efficiency was higher at lower irrigation level (KAHN & AGAR- * Contribution from the Egypt/EEC Coopera- tive Project SEM/01/220/021.
