Abstract
An experiment was conducted on Ferric Acrisol under rainfed conditions during the 2010 minor crop growing season in Kumasi, Ghana to determine the effect of different tillage practices on Akposoe maize (Zea mays .L) variety performance. The experiment was arranged in a randomised complete block design with four treatments namely disc ploughing only, disc ploughing followed by disc harrowing, disc harrowing only and No Tillage. Each treatment was replicated three times. At ten weeks after planting, the disc harrowing only plots produced the tallest plant, biggest stem girth, highest number of leaves per plant, and highest leaf area index. On the other hand the No Tillage plots presented the shortest plant, smallest stem girth, lowest number of leaves per plant, and smallest leaf area index. At harvest, the longest root, highest dry matter yield and highest fresh cob weight were obtained from the disc harrowing only plots while the shortest root, lowest dry matter yield, lowest fresh cob weight, lowest dry cob weight, and smallest 1000-seed weight were located in the No Tillage plots. The disc ploughing followed by disc harrowing treatment produced the highest dry cob weight and highest 1000-seed weight. There was no significant difference in Akposoe maize plant growth, dry matter yield and yield components between the disc harrowing only and the disc ploughing followed by disc harrowing treatments. Thus, considering the soil and weather conditions of the experiment, the optimum tillage practice for producing Akposoe maize variety is disc harrowing only.
