Abstract
Kafi EL-Sheikh Governorate is the main area for sugar beet cultivation, which produce almost 80-90 % of the total national production. One way of increasing production of sugar beet could achieved by proper utilization of fertilizers and increasing the efficiency of added NPK as well as expanding of sugar beet cultivation in reclaimed areas. The objective of the present investigation is to study in field experiments the effect of soil salinity, N levels and K fertilization on sugar beet yield and yield components. The chemical composition of the plant was also undertaken. Using the strip-plot design for two successive seasons, the main plots of the experiment were two soil salinity levels: Kafi EL-Sheikh location (KS) which represented low level of soil salinity (EG3.23 dSlm) and EL-Harnoul location (EH) which represented high level of soil salinity (EC4.52 dS1m). The sub-plots were four potassium fertilization rates 0, 48, 96 and 120 Kg KzO/feddan and the sub-sub-plots were five nitrogen levels, 0,30,60, 90 and 120 Kg Nlfeddan. The investigation was carried out at EL-Kolleaa village (ELHamoul district) and at the Faculty of Agriculture Experimental Farm (Kafi EL-Sheikh district) during 1994/95 and 1995/96 seasons.
