Data from a study on the growth rate of paprika plants grown under small-scale farming conditions in southern Africa.
paprika
A tibble with 1070 rows and 5 variables:
replicate number
fertilizer treatment
plant variety
plant number
height of the plant (cm)
The data were obtained from https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/25747, and the original paper on the study can be found at https://link.springer.com/article/10.1007%2Fs10457-011-9415-2.
The study was conducted in 2007 and 2008 in Malawi using a split plot design with five replicates. The researchers compared 4 fertilizer treatments ((1) control, (2) inorganic fertilizer, (3) Gliricidia biomass, and (4) Gliricidia biomass plus half the recommended dose of fertilizer for paprika) and 6 plant varieties ((1) Papri-King, (2) Papri-Queen, (3) Papri-Excel, (4) Papri-Supreme, (5) Papri-Ace, and (6) PX1140 4601). The fertilizers were applied to the main plots, and the varieties were assigned to the subplots within a main plot. For each replicate, 10 plants were randomly chosen from each treatment and variety treatment combination and observed over 20 weeks. This dataset contains observations from week 4 of the data in 2008.
