ASSESSMENT OF THE IMPACT OF PROFEBA ON ACID SOIL, AND THE SORGHUM AND MILLET YIELDS UNDER RIDGE AND HOE TILLAGES IN SAHELIENNE ZONE IN MALI
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
Mali faces a serious threat to its crop production due to increase in soil acidity. Keeping this aspect in mind, soil experiments were conducted at Siguidolo, located in sahelienne zone of Mali. The effect of profeba, ridge tillage, and hoe tillage on soil fertility was determined in addition to millet and sorghum yield. Profeba was applied at optimal levels as control, profeba, profeba + urea, profeba + urea + TPR, or profeba + urea + lime. Profeba was found to have a prospective liming effect, as it elevated pH from 4.78 to 5.33. This effect was augmented to about 5.58 when supplemented with mineral fertilizers and lime. All the different combinations of profeba produced superior millet and sorghum yields, especially with better rainfall. Profeba in combination with urea alone or urea with TPR produced the best grain yield. Compared to hoe tillage, ridge tillage gave a higher millet and sorghum grain yield. The highest VCR, although less than 2, was acquired under profeba + urea for millet and sorghum.
