Effect of Cover Crops, Lime and Rock Phosphate on Maize (Zea mays L.) in an Acidic Soil of Northern Guinea Savanna of Nigeria JARTS
Jibrin, J. M.; Chude, V. O.; Horst, W. J.; Amapu, I. Y..
Phosphorus deficiency is the major constraint to maize production in acidic soil of Heipang (9°38’, 8°53’) in Northern Guinea Savanna of Nigeria. The soil is high in sesquioxides and soluble aluminum and has high phosphate sorption capacity. To address this problem, a field trial was conducted between 1996-1997 to assess the responses of six tropical cover crops and maize to lime and applied rock phosphate and to evaluate the effect of these treatments on the performance and P nutrition of succeeding maize. Results of the trial showed that planting Chamaecrista rotundifolia, Lablab purpureus, Mucuna pruriens, and maize-Chamaecrista rotundifolia intercrop reduced the leaf Al concentration of succeeding maize by more than 38%. Although none of the six cover...

Influence of inorganic and organic fertilization on microbial biomass carbon and maize yield in two soils of contrasting pH Agrociencia
Arrieche-Luna,Elena; Ruiz-Dager,Magaly.
Inappropriate soil management practices that have been applied in the Yafacuy River basin, Venezuela, have led to the loss of soil organic matter and crop productivity. The incorporation of composted organic residues has been suggested as an alternative management practice in order to increase organic matter (OM) content and crop yield in these soils. The objective of this study was to determine the effects of different application fates of an organic fertilizer obtained from sugarcane industry wastes, filter cake and bagasse with or without inorganic fertilizers, on microbial biomass carbon (MB-C), soil organic carbon (SOC), maize (Zea mays L.) yield and N, P, K content in the maize leaves, in Yafacuy River basin. The experiments were established in an...

The Possibility of a Green Revolution in Sub-Saharan Africa: Evidence from Kenya AgEcon
Otsuka, Keijiro; Yamano, Takashi.
It is widely believed that a Green Revolution similar to the one achieved in Asia is impossible in Sub-Saharan Africa. Although grain yields have been stagnant in this region, there are some signs of the intensification of farming systems in the face of growing population pressure on limited land resources. In this paper we focus on the new farming system based on the use of manure produced by dairy cows, which may be termed an “Organic Green Revolution.” Using the farm household data collected from Kenya, this paper demonstrates that the Organic Green Revolution has a potential of doubling maize yields in highlands of Kenya.
Tipo: Journal Article Palavras-chave: Green Revolution; Agricultural Revolution; Organic Green Revolution; Dairy cows; Manure; Chemical fertilizer; Maize yield; International Development.
