Abstract
Abstract: Tillage is a very important crop production activity which may affect crop performance differently. An experiment was conducted during the during the 2009 and 2010 major crop growing seasons in Kumasi, Ghana, to compare the effect of four different tillage practices on Asontem cowpea (Vigna unguiculata (L) Walp) performance. The treatments consisted of disc ploughing only, disc ploughing followed by disc harrowing, disc harrowing only and no tillage. There was significant difference in Asontem cowpea growth, dry matter yield and yield components between tillage practices. Disc ploughing followed by disc harrowing gave the best results producing the highest percentage seedling emergence, tallest plant, biggest stem girth and greatest number of leaves. Furthermore, disc ploughing followed by disc harrowing resulted in the longest root length, highest dry matter yield, highest number of pods per plant, highest number of seeds per pod and highest 1000 seed-weight. The no tillage plots produced the shortest plant, smallest stem girth and smallest number of leaves. In addition, the no tillage plots gave the shortest root length, lowest dry matter yield, smallest number of pods per plant, smallest number of seeds per pod and smallest 1000 seed-weight. Therefore, considering the soil and weather conditions of the experiment the best tillage practice for Asontem cowpea growth and yield is disc ploughing followed by disc harrowing.
