Germination variables

Usually in agronomic studies, there exists the necessity of how the germination process of certain plant or variety works. It usually involves consecutives evaluations in time of a germination variable. Flavio et. al (2019) provides a germination study that includes germination evaluations that we are going to mimic to recreate an entire example of how an rfbapp along with Field Book App, a mobile phone application, can integrate each other to collect data into the field.

Creation of variables

In aforementioned study, there is one variable named D, which denote the number of germinated seeds in a certain day. For example: D1 number of germination seeds at day 1. The study especify the number of seeds initially planted are 50 per experimental unit (EU). Thus, the researcher should count how many seed successfully germinated in a certain day from the initial sample of 50 seeds. For example: in day 1, the number of germinated seeds are D1=39in first EU.

To create a variable list in `rfbapp`` that satisfy the aim of our study, we identify the followig attributes:

In rfbapp we can create quantitative variables as follows:

vars <- create_fbapp_template(variable = "D", type = "numeric", details = "Numer of germinated seeds", ntime = 10)
vars

Now we export these set of variables via:

rfbapp::write_rfbapp(vars,file = "germination_variables.trt")
