Optimizing maize yield in West and Central Africa

A study was conducted in four different environments of Ghana. The aim was to optimize maize by developing maize hybrids tolerant of high plant density. The hybrids were evaluated under three plant densities, namely, high (88,888 plants/ha), medium (66,666 plants/ha), and low (53,333 plants/ha). The experimental design was 8 x 6 alpha lattice with split plot. The experiment was replicated two times in each of the four environments. Data on different phenotypic traits were collected either by measuring or counting.

Methods
The data are collected from field experiments. Most of them were directly entered into Excel sheets using a tablet in the field, but some were recorded into a hard copy of data collecting sheets. Some data were transformed, but both the original and the transformed data are all available in the Excel file.
