Abstract
<jats:p>The result of evaluation of correlation relationship between spectral indices of NDVI vegetation and NDMI humidity calculated on the basis of Earth remote sensing data obtained using Sentinel-2 satellite is shown. The research object is located in the Volgograd region and is an array of drip irrigation system with a total area of approximately 120 hectares, consisting of 11 sites. In 2024, a table carrot culture (Daucus carota) was grown on this territory. The nature of the distribution of random variables NDVI and NDMI does not correspond to the normal (non-Gaussian distribution) law is noted. The Shapiro-Wilkie W-test for all observed values of the NDVI vegetation index is in the range of 0.748... 0.871, for the NDMI humidity index – 0.748... 0.884. This indicates a non-Gaussian distribution with statistical significance (p = 0.01). The Munney-Whitney U-test values are 212... 360. This indicates statistically significant differences (p = 0.01) between the NDVI vegetation index and NDMI humidity index samples. NDVI and NDMI values correlate statistically significantly (Spearman rank coefficient rs = 0.41…0.95) with significance level p = 0.01. The paired Spearman correlation coefficients rs between NDVI and NDMI for one field are in the range of 0.85... 0.95 with a higher significance level p = 0.001.</jats:p>
