| Abstract | ||
| 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. | ||
