INTERCROPPING EFFICIENCY OF SOME MAIZE HYBRIDS ON PEANUT IN SANDY SOILS

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.
