| 520 | _aA Long-term field trial was conducted at Mallawi Agric. Res. St. (Middle Egypt), on clay loamy soil. It started in 2001/2002 to 2007/2008 seasons. The objective of this study was to compare different rotations i.e one prevailing rotation and two proposed intensive rotations that are assumed to be more productive, sustainable and less weedy. The results showed that yield of crops in the two proposed rotations were higher than those in prevailing rotation in both cycles. The NPK of soil contents and organic matter (OM) percentages were more improved under the two proposed rotations as compared with the prevailing rotation in both cycles. The results also revealed that the increase in soil contents of NPK and OM were higher in the latter year (after the second cycle) as compared with the first cycle. The intensification index in the proposed (I) and proposed (II) was 2.50 and 2.60, respectively as compared with the prevailing rotation 2.05. The density of associated annual weeds was more reduced which reached only 50% of the prevailing rotation. | ||
