An evaluation of soil-water management on an Alfisol in the semi-arid tropics of Burkina Faso
1987
Perrier, E.R.
Experiments were undertaken at Kamboinse Ex2048periment Station in Burkina Faso to compare the yield advantages of flat and ridged soil-surface treatments, with and without mulching and with open and tied ridges, to obtain data on cultivation practices that conserve water and increase infiltration. Data on grain and dry-matter yields and the growth characteristics of two varieties of sorghum and three of pearl millet used in the experiments over 2 years are presented. It was found that mulch can significantly increase yields regardless of the method chosen for water conservation: flat, open ridges, or tied ridges. The best system was the use of tied ridges with mulch. The traditional method of flat sowing restricts crop yield. This was found to be particularly true for the improved varieties, for which plowing was found to be necessary for increasing their yields. Plowing before sowing increased the sorghum (E 35-1) yield by
