1. Maize-cowpea intercropping as an ecological intensification option for low input systems in sub-humid Zimbabwe: productivity, biological N2-fixation and grain mineral content.

Poor soil fertility and erratic rainfall constrain crop production in rain-fed smallholder farming systems in sub-Saharan Africa. Integration of cowpea, a drought tolerant and N2-fixing crop into maize-based cropping systems is a risk-averse strategy that also improves N cycling.  A field experiment was carried out during 2017/18 and 2018/19 cropping seasons in Zimbabwe to assess the effect of intercropping and fertilizer micro doses on productivity, N2-fixation and grain mineral content....
