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., 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. , , ## Optimizing_maize_yield_in_West_and_Central_Africa

## Description of the data and file structure

The data are phenotypic data of maize hybrids.  The data are collected from four environments. The environments are written in full in the excel, except “Legon minor season” which is written as Legon_Mi, and “Legon off season” which is written as Legon_off. The data are put in one Excel file, but two separate sheets. The first excel sheet has data which were collected during harvesting and after harvest, and the second excel sheet has data which were collected before harvesting. All the data were collected from four environments, except days to maturity, chlorophyll content, and tassel size which were determined only from one, two, and three environments, respectively. For the environments where these parameters (traits) were not collected, the Excel cells are filled with \"n/a\". Plant Density (PD), Enviro...,
