Each farmer experimenter rated the performance of the legume fallows against the control with indicators which they developed in the second year of experimentation.
With the exception of phosphorus, treatment effects on legume growth were marginal.
Legume-based cropping systems have reduced carbon and nitrogen losses.
It is concluded that grass+legume mixtures increased milk yields on farms.
The present study pointed to the critical role of legumes, especially perennial alfalfa, for increasing the energy efficiency of a cropping system.
However, other experiments have indicated the beneficial effects of perennial legumes and no-till agriculture on soil nitrogen.
This paper reports the results of on-farm testing of grass+legume pastures assessed in terms of milk production in dual-purpose systems.
Absent from private sector research, not surprisingly, are many crops cultivated by the world's poor, including small-grain cereals, tubers and legumes.
