Effect of Shoot Trimming on Yield and Quality of the Peanut Cultivar “Chiba P114”

Abstract

A new peanut cultivar ‘Chiba P114’ has a high sucrose content. However, its sucrose content is not always high. Its branches are also too long for harvesting. In order to produce peanuts with a high sucrose content and to improve the harvesting operation, we investigated the effects of shoot trimming on the yield and seed quality. The earlier the shoot was trimmed, however, the greater the decrease in yield. However, shoot trimming at 70 days after flowering increased the sucrose content, regardless of sowing date. The results showed that shoot trimming at 70 days after flowering would be an appropriate practice for production of peanuts with a high sucrose content while minimizing the reduction in yield.
