Abstract

Field experiments were conducted in Nigeria, during the 2006/07 cropping seasons, to find out the effects of tillage practices and intercropping on the growth and yield of maize. The treatments comprised 3 tillage practices (CT, MT and NT) and cropping systems. At 8 WAP, the tallest plants of 134 cm were obtained with CT and sole cropping, while the shortest plant, about 84 cm, was obtained from NT and intercropping. Application of CT and sole cropping also had the widest leaf of 451 cm2 per plant, while a leaf about 231 cm2 was obtained from NT and intercropping. The same trend was obtained for the number of leaves per plant with CT and sole cropping having the highest value (11 leaves per plant). Land equivalent ratio was greater than unity in all treatments during both seasons. Aggressivity was negative for CT and MT and positive for NT, while the relative crowding coefficient was positive for all treatments. Maize grain yield was significantly highest, about 3 t/ha, under CT and sole cropping while the least yield of 2.12 t/ha was obtained from NT and intercropping. The results indicated that maize growth, intercropping efficiency and yield were well supported with CT
