Abstract:
Summer and winter vegetable crops responded differently depending on the side of the ridge on which they were planted during the winter season of central and northern Sudan.
Summer vegetables like okra, purslane and jew's mallow gave the best yield and quality when planted on the southern side of the ridge.
The revorse was true for winter crops like tomato, potatoes, garlic and sweet peppers.
The eastern and western sides were comparable to each other in yield and quality but intermediate to those of the northern and southern sides for both winter and summer crops.
This differential effect on yield and quality of the different season crops, grown during winter, was attributed to the difference in soil temperature.
The northern side gave the lowest temperature followed by the western side, then the eastern side while the highest temperature was recorded on the southern side of the ridge.
