Abstract

Abstract Intercropping maize with legume crops was reported to be able to increase grain yield of maize. This study aimed to examine the possibilities to increase yield performance of maize by changing the row patterns and additive intercropping with several varieties of peanut in dryland of East Lombok, Indonesia. The experiment was arranged according to Split Plot design with three blocks and two treatment factors, namely intercropping with peanut (K0= monocropped maize; K1= intercropping with Hypoma-1; K2= Katana-1; K3= Tasia-1 peanut variety) as the main plots, and row patterns of maize (R1= double row; R2= normal row) as the subplots. Peanut was seeded two weeks before maize. The results indicated that additive intercropping of maize with peanut and changing from normal to double-rows significantly increased maize grain yield, and there were significant interaction effects on maize grain yield, number of seed rows per ear, weight of 100 grains, and harvest index. Although in general changing from normal to double row pattern increased grain yield, significant increase was found only on the maize plants intercropped with Katana-1 peanut variety, from 10.78 ton/ha under normal to 11.95 ton/ha under double row pattern, while grain yield of monocrop Ped maize was only 9.23 ton/ha.
