This
study examines the ability of different cropping sequence (including or not including alfalfa) to
improve bean productivity in calcareous and alkaline soils of the old Nile (high) terraces in North of Sudan. The soil in the experimental
site is sandy clay to sandy clay loom. Soil properties were examined before
planting and after bean harvest. Salinity which was
greater in non-reclaimed soil decreased regardless of the cropping sequence.
Soil alkalinity remain higher than 8 in all cropping sequence after more than
6-7 cropping seasons. P (Olsen) and calcium
carbonate showed inconsistent trends regardless of the cropping
sequence. Organic carbon increased after bean
cultivation in both cropping sequence. Change in growth parameters as
affected by cropping sequence were significant
in various levels, however, that determining yield were not. Presence of
alfalfa in the cropping sequence increased seed yield, number of pods per
plant, number of seeds per pods, pod length, plant length, leaf length, leaf
width, fresh plant weight, nodule number. However seed weight was decreased.
