Two field experiments were carried out at Ismailia Agricultural Research

S:ation, Agricultural Research Center under sprinkler irrigation in sandy soils in 2002

rd 2003 to study the efficiency of some maize hybrids; SC 155, TWC 321, and TWC

352 for intercropping under different patterns; pure stand maize, pure stand peanuts

. addition to 4 mixed patterns. All rows were planted with peanut then maize was

p'anted on peanut rows in different ratios; mixed 1 (Ml) 2:2 ratio maize on peanut

rows: pure stand peanuts, 30 cm between maize hills and one plant/hill, mixed 2 (M2)

2:2 ratio, 50 cm between maize hills and 2 plants/hill, mixed 3 (M3), 1:1 ratio, 30 cm

:etween hills and one plant/hill, mixed 4 M4, 1:1 ratio, 50 cm between hills and 2

tantsihill. Peanut variety Giza-5 was used. Treatments were laid out in a randomized

complete block design with 3 replications. Results revealed that the highest values of

peanut yield and its components were obtained when yellow maize hybrids (SC 155

ard TWC 352) were associated. lntercropping system Ml was accompanied with the

ghest peanut yield. Maize x intercropping pattern interaction was significant for all

traits. The highest pod yield was found when yellow maize hybridš were planted

according to Ml pattern. lntercropping pattern Ml had the highest values of land

equivalent ratio and relative crowding coefficient as well as the lowest values of

açgressivety.
