Abstract

Two Field Experiments were carried out at Nubaria Agric. Res. Station
during the two successive seasons 1998 and 1999 to study the effect of tillage
treatments and some intercropping systms ( 2 : 2, 2 : 4 , 1 : 3 and :3:3 )for (soybean:
maize) . Besides solid stand of soybean and solid stand of maize on yield of maize
and its attributies of maize and soybean and competitive relations of soybean and
maize . The obtained results indicated that tillage systems and intercropping patterns
had significantly affected on seed yield of soybean and maize. The highest seed
yield per I feddan was obtained from tillage systems in the two seasons to each two
crops .Also , intercropping patterns had significant effect on all characters studied.
Maximum seed yield of maize was obtained with sowing patterns of 2 row soybean:
4 rows of maize. The solid stand gave higher seed yield of soybean and grain yield
of maize.
The results indicated that land equivalent ratio LER of maize and soybean
valued more than one moreover, maize was always dominate crop whereas soybean
was dominated.
