Application of satellite images in cotton cultivation

In this project, 931, 932 and 933 hybrid cottonseeds were used. ‎This project was carried out on an area of 30 hectares. NDVI index is always helpful in assessing ‎plant health on farm. The most important reason for this capability is that the changes in this index ‎are consistent with the physiology of the plant and in simple terms with the changes in pigments and ‎staygreen of the plant cover. According to the trend of changes in NDVI index, hybrid cotton 933 ‎had the best greenness during the growing period. The variety 933 is the oldest figure in this study. ‎On the other hand, 931, which has the lowest NDVI, is the earliest figure. As the results show, the ‎yield of cotton transplanting was significantly differences by cotton seed planting method. ‎Transplanting yield is more than twice that of cottonseeds in November, especially for cultivar 931. ‎As expected, the highest yield was observed in transplanting 931 and the lowest yield was taken in ‎‎933 seed treatment. With help of NDVI index in September, it is possible to comment on the early ‎maturity of cotton cultivars.‎
