Supplementary files for ground-based remote sensing of sesame drydown

This is a collection of supplementary materials in support of the article entitled "Using normalized difference vegetation index to estimate sesame drydown and seed yield," which was accepted for publication in Journal of Crop Improvement as of 31 October 2020. doi: 10.1080/15427528.2020.1846101 

Supplementary file 1 - list of computer program. This list documents Minitab macro, dryrate.mac, that was written to do regression analysis for sesame drydown data collected at the Texas A&M AgriLife Research Center at Uvalde. The macro automates the process of running m x 9 linear regressions, where m represents the number of sesame plots/genotypes and 9 the number of vegetation indices.

Supplementary file 2 - sample input data to macro dryrate.mac. The file contains nine vegetation indices measured five times from six plots during sesame drydown in the 2019 growing season.

Supplementary file 3 - sample output data. This file contains the outputs of dryrate, including selected regression coefficients for
each of the six sesame plots.

Supplementary file 4 - Figure S1. Scatter plots of average values of nine vegetation indices for 60 sesame genotypes measured five
times from 6 September 2019 to 6 October 2019.

Supplementary file 5 - Table S1. Values of the slopes depicting the regressions between nine vegetation indices and time for 60 sesame genotypes.

Supplementary file 6 - Table S2. Average values of different vegetation indices measured on Day 9 during drydown for 60 sesame
genotypes.

Supplementary file 7 - Figure S2. Relationships between sesame seed yield and the slopes of regressions between nine vegetation indices and time during the drydown period.

Supplementary file 8 - Figure S3. Histograms of the coefficients of determinations for the 60 linear regressions relating different
vegetation indices with time (days during sesame drydown).

Supplementary file 9 - Figure S4. Ranking from the highest to the lowest of the maximum NDVI (normalized difference vegetation index) for the 60 sesame genotypes, along with the measured seed yields for the corresponding genotypes.
