Kotu, Bekele HundieKihara, JobLuanda, Y.Wikedzi, I.Lyimo, S.[Economic analysis of fertilizer options for maize production in Tanzania]Economic analysis of fertilizer options for maize production in Tanzania

Traditionally, crop production in sub-Saharan Africa (SSA) depends primarily on mining soil nutrients. Integrated Soil Fertility Management (ISFM) is an approach for intensifying agriculture in SSA that aims at maximizing the agronomic efficiency (AE) of applied nutrient inputs. ISFM contains the...

This is a comprehensive dataset specifically on crop response to fertilizers and is obtained from published journal articles, thesis and proceedings spanning at least 5 decades. It represents all the agriculturally productive regions of Ethiopia. The data contains information on region, crop type...

Tamene, LulsegedMponela, PowellNdengu, GiftKihara, Job[Assessment of maize yield gap and major determinant factors between smallholder farmers in the Dedza district of Malawi]Assessment of maize yield gap and major determinant factors between smallholder farmers in the Dedza district of Malawi

The application of nitrogen in a soil under agricultural production is subject to several pathways including de-nitrification, leaching and recovery by an annual crop. This is as well greatly influenced by the management practices, nitrogen source and soil conditions. The main objective of this s...


Kimetu, J.M.Mugendi, DNBationo, B. AndréPalm, C.A.Mutuo, PKKihara, JobNandwa, SMGiller, Ken E.[Partial balance of nitrogen in a maize cropping systems in humic nitisol of Central Kenya]Partial balance of nitrogen in a maize cropping systems in humic nitisol of Central Kenya

Crop production in sub-Sahara Africa is constrained by low soil phosphorus (P) content. A study was conducted in western Kenya to explore alternative P inputs and ways of optimizing their effectiveness and profitability. A field experiment established in 2007 studied the effects of Minjingu phosp...
