Abstract:

Timely sowing is one of the key cultivation measures for increasing peanut yield and achieving a bumper harvest. To determine the optimal sowing date for Pukehua 11 and provide a scientific basis for peanut production, this study set five sowing date treatments, including May 1, 11, 21, 31, and June 10, to systematically investigate the effects of different sowing dates on the growth process, agronomic traits, yield, and quality characteristics of Pukehua 11. The results showed that as the sowing date was delayed, the emergence time, flowering time, and growth period were shortened. The main stem height, lateral branch length of peanuts were higher under the sowing date of May 11 and May 21. Sowing date had no significant effect on the branche number per plant. Under the May 11 sowing date, the pod yield and kernel yield of peanuts were higher than those under other sowing dates. With the delay of the sowing date, the crude fat content, oleic acid content, and the ratio of oleic acid to linoleic acid gradually decreased, while the crude protein and linoleic acid content increased. In conclusion, May 11 can be recommended as the suitable sowing date for Pukehua 11.
