Abstract
Two field experiments were conducted in 200012001 and 200112002 growing seasons at Sakha Agric. Res. Station Farm, in clayey salt affected soils, to stUdy the effect of three soil wetting depths (30, 45 and 60 cm), two ploughing depths (1r cm and 30 cm) and three potassium fertilizer levels (24, 48 and 72 kg K20Ifed.) on sugar beet yield, Its water relations and some soil properties. Splil-l'lplit plot design with four replicates was used. Results indicated that, under salt affected soli condit ons, moderate applications of irrigation water, which was watered till a depth of 45 cm and deep ploughing technique (30 cm) with application of 72 kg K20/fed. were the best combination, which enhanced the growth of sugar beet plants, and produce the highest beet yield, average root weight, root size and sugar yield. With regard to irrigation water consumption. it is noticed that values of water consumptive use increased as the soil wetting depth increased. On the other side. values of ater consumptive use decreased with increasing ploughing depth. due to the greater ability of root system to reach. and use irrigation water in the deeper plou~hing treatment. Concerning the water use efficiency for root and sugar yields, data clearly showed that, the soil wetting depth of 45 em with deep ploughing technique, achieved the highest values of water use efficiency. While the lowest value was gained from soil wetting depth of 60 em with shallow ploughing. With respect to chemical properties, after harvesting sugar beet. the mean values of ECe and SAR generally decreased, with increasing soil wetting depth, in both seasons. as well as under tilled treatments, compared with the values obtained before applying Ihe different treatments.
It can be concluded that irrigation to a depth of 45 em. and deep plou!ilhing technique are the best combination treatments under salt affected soil to obtain favourable physico-chemical properties and consequently high sugar beet yi Id at North Delta region.
