These recent summer cover crop studies under commercial farm fields have shown that potato tuber yields can be increased if a summer sorghum-sudan crop is grown with limited irrigation, harvested for hay, or an aboveground sorghum-sudan incorporated crop is grown before the potato crop; the yields increased by 12% to 30% when compared to a wet fallow system
serves the same purpose as crop rotation, but at a higher level, since while crop rotation involves use of the same parcel of land; the fallow system
involves physical movement to other parcel of land.
One of the most interesting features of the improved fallow system
is that it allows for forms of R&D that farmers can do on their own.
The Pwo traditionally practice short-cultivation, long-fallow farming, growing upland rice as a staple and other crops using a rotational fallow system
in mixed deciduous forest.
The winter wheat-summer fallow system
serves as the baseline for comparison since it is the predominant dryland cropping system of the region.
Residue production in the spring wheat/chemical fallow system
ranged from 3660 to 4210 kg [ha.
Fundamentals of water conservation practices used in the summer fallow system
3 in) of water per year more than a bare fallow system
Generally, the decline of food production in upland farming systems in the tropics has often been attributed to the lack of adoption of modern farming technologies and farmers have been unable to replenish nutrients lost in continuous cultivation which has replaced traditional bush fallow systems
(Hossner and Juo, 1999).
It encompasses principle of some ancient practices, including the shifting cultivation and the bush fallow systems

The quality of residues in legume plants rotated with rice crops might be the reason for greater N uptake compared to rice after fallow systems
