use soil nutrients more efficiently than sole crops, because of a higher N- recovery and increased dry matter yields [6 and 7].
Considering that most bean production takes place in an intercrop
system with maize and sorghum, understanding quality of seed produced and participatory planning, and testing of practices that help produce seeds of acceptable quality under different intercropping system would be a sound strategy for the assurance of the supply of high quality seeds for the area.
Kaiser and Lesch (1977) revealed similar results, demonstrating that the increase in CP concentration can reach as high as 78% from a monoculture corn to an intercrop
corn with lablab bean.
The present study, however, provides a new dimension to this field, in that the mixture ratios and residue amounts were based on dry matter yield of intercrops
from a related field study (Rusinamhodzi et al.
in a Maize and Beans Intercrop
by Soil Fertility Management.
The Land Equivalent Ratio (LER) index was utilized to evaluate intercrop
efficiencies with respect to sole crops (Ciftci and Ulker, 2005).
Additionally, the roots of intercrops
freely intermingle, leading to a complementary and more efficient use of nutrients, especially nitrogen (Natarajan and Wiley 1980).
While coconut-citrus intercrops
I and II respectively enjoy 26.
In general, lentil growth measured by plant height, leaf and sympodial number per plant, and yield attributes (pod numbers per plant, grain numbers per pod and 100-grain weight) were greater in intercrops
than monocrops (Table 1).

Therefore, the combined yields of two crops grown as intercrops
can be higher than the yield of the same crops grown as pure stand.
Where Sa and Sb are sole crop yields of the component crop a and b, and Ya and Yb are the yields of component a and b in the intercrops
