| Descrizione: | Introduction. Climate change and low-intensity cropping technologies limit cowpea [Vigna unguiculata (L.) Walp.] yield in sub-Saharan Africa. Objective. To implement and optimize high-intensity climate-smart cropping systems for cowpea. Materials and methods. Cowpea was planted using four seeds per hill, spaced at 75 × 20 cm in a randomized complete block design with four replicates, and later thinned to the required stand at the Savanna Agricultural Research Institute, Manga, Ghana, in 2021 and 2022. Four planting designs were used: a single row with two plants per hill at the center of the ridge (66 667 plants/ha); a single row with one plant per hill at the center of the ridge (33 333 plants/ha); a double row with two plants per hill on both sides of the ridge (133 333 plants/ha); and a double row with one plant per hill on both sides of the ridge (66 667 plants/ha). Days to 50 % and 90 % flowering, pod load and pod length, number of seeds per pod and 100-seed weight, and grain and biomass yields were recorded. Results. Planting designs and plant densities had no effect on the number of days to flowering. A single row with two plants per hill or a double row with one plant per hill increased pod load. A single row with two plants per hill or a single row with one plant per hill improved the number of seeds per pod. Planting a single row of two plants per hill or a double row of two plants per hill optimized grain and biomass yields. Conclusions. Different planting designs and plant densities can enhance pod load, improve the number of seeds per pod, and optimize cowpea grain and biomass yields. |
