Combined application of biofertilizers and inorganic nutrients improves sweet potato yields por Mukhongo, Ruth Wilhem, Tumuhairwe, J.B., Ebanyat, Peter, AbdelGadir, Abdel Aziz H., Thuita, Moses N., Masso, C.

“…Two kinds of biofertilizers were compared to different rates of phosphorus (P) fertilizer when applied with or without nitrogen (N) and potassium (K). The sweet potato response to treatments was variable across sites (soil types) and seasons, and significant tuber yield increase (p < 0.05) was promoted by biofertilizer and NPK treatments during the short-rain season in the Ferralsol. …”

Heterogeneity in farmers production decisions and its impact on soil nutrient use: results and implications from northern Nigeria por Berkhout, Ezra D., Schipper, R.A., Keulen, H. van, Coulibaly, O.

“…In farm plans of the most risk-averse households, the production of cereals for subsistence consumption dominates and leads to negative soil nutrient balances, especially for potassium. Farmers who place a large importance on gross margins are likely to benefit most from policies aimed at enhancing profitability through improving functioning of markets. …”
