Abstract

The objective of this work was to investigate the effects of early or late harvest times on the changing yield and yield component and the seed quality of peanuts. It was determined that harvest time had statistically significant effects on plant height, primary branch number, primary branch length, per plant pod number, per plant yield, 100 seed weight, shelling percentages, pod yield, fresh and dry weight, harvest index, oil content, protein content, carbohydrate and ash ratio andoleic/linoleic acid ratio. The highest pod yield was determined by the third harvest times in both years, because of having a high podper plant yield, per plant pod number, 100 seed weight, shelling percentage and harvest index. The protein and oil ratios were increased by delaying the harvest time, whereas the carbohydrate ratio decreased. In particular, it was revealed that the oleic/linoleic acid ratio increased because of increasing seed size and the amount of oleic acid throughout the delay in the harvest. As a result of this study although fourth and fifth harvest times were observed in terms of the highest 100 seed weight, there were problems due to the harvest lost and the formation of substances that threaten human health such as aflatoxin in the delayed harvest times. Therefore, there is no point waiting to take a very high pod yield at late harvest times. It was suggested that earlier cultivars or earlier planting and harvest times should instead be used for pod yield and healthy crops
