ChickpeaEnd.dat {asremlPlus}R Documentation

A large data set comprising the end of imaging data from a chick pea experiment conducted in high-throughtput greenhouses

Description

The data collected after imaging had been completed on the 1056 plants in the experiment reported by Atieno et al. (2017). The design employed for the experiment was a split-plot design in which two consecutive carts formed a main plot. The split-plot design assigned 245 genotypes to main plots, the genotypes being unequally replicated 2 or 3 times. Treatments (non-saline, saline) were randomized to the two subplots (carts) within each main plot.

The columns in the data.frame are: Smarthouse, Lane, Position, Zone, Mainplot, Subplot, Replicate, xLane, xPosition, Genotypes, Treatments, Biomass, PlantHeight, SenescenceRank, TotalPods, FilledPods, EmptyPods, SeedNo, TotalSeedWt, SeedWt100.

The columns Smarthouse, Lane and Position uniquely identify the rows of observations. Zones are groups of 4 Lanes, Mainplots are the 44 pairs of consecutive Subplots within each Zone, and a Subplot is a cart containing a single plant. The columns xLane and xPosition are numeric covariates for location within a Smarthouse. Genotypes and Treatments indicate the genotype and treatment that each plant was allocated. The response variables are Biomass, PlantHeight, SenescenceRank, TotalPods, FilledPods, EmptyPods, SeedNo, TotalSeedWtand SeedWt100.
