Agronomic assessment of phosphorus efficacy for potato (Solanum tuberosum L) under legume intercrops
(Taylor & Francis, 2019)Phosphorus (P) is an essential element and its efficient use is of global importance. This study evaluated the effect of growing potato under legume intercrops on P uptake and use efficiency indices: P harvest index (PHI), ... -
Increasing potato equivalent yield increases returns to investment under potato-legume intercropping systems
(De Gruyter, 2019-11)In order to enhance sustainable intensification of potato-based cropping systems, especially in sub-Saharan Africa (SSA), there is a need to investigate the economic viability of investing in this lucrative venture. This ... -
Intercropping Optimizes Soil Temperature and Increases Crop Water Productivity and Radiation Use Efficiency of Rainfed Potato
