| Abstract | ||||
| The present study was carried out in two succeesive seasons of 1 ~98/1999 and 1999/ 2000 \0 find out the relative importance of irrigation interval and hoeing frequency under two 'Irrigation systems on yield and quality of sugar beet in sandy soil at Ismalilia Governorate. The study included 12 treatments which were the combination between two Irrigation systems (drip and surface). two hoeing regimes (ellery 7 and 14 days) ano tnrae irrigation intervals (every 3, 5 and 7 da s). The results showed that surface irrigation out yielded drip Irrigation system; in most studied characters. Hoeing at intervals of 7 days produced higher roolle~gth, rool diameter, root and top yields! fed , sucrose % TSS %, sugar yield 1 fed and LUE compared with 15 days ones. While purity % was not affected by hoeing interval. Irrigation intervals (at 3,5 and 7 days) exercised a significant effect on all studied characters except, purity % which was not significantly affected For the interaction effects, the effect of hoeing intervals on roo! yield was s nificant only when surface irrigation was followed. Sucrose % behaved like root I~ield and sugar yield lIed , prolonging hoeing interval to 15 days, decreased sucrose % and sugar yield I fed. Sugar yield I fed I day showed similar reaction to increasing hoeing interval only under surface irrigation. SImple correlation coefficIents proved positive and highly significant correlation between sugar yield (11 fed) and the studied eight characters. According 10 Ihe oolained results, it could be recommended that surface rrigation system Is considered the best one as it, hoeing at intervals of 7 days and scheduling irrigation at 5 days interval. This treatments were more suitable for growing sugar beet plants under newty redaimed land conditions. . | ||||
