Interpretive Summary

This field experiment, initiated in 2013, continued to examine the effects of different rates and timing of controlled-release urea (CRU) on yield and economical returns of ratooned sugarcane in Wuming county of Guangxi.

Guangxi, the largest sugarcane-growing province in China, accounts for about 70% of the sugarcane production in the country. Sugarcane is a tropical and subtropical perennial crop with a long growing season of about 8 to 10 months. A high yielding crop of 50 to 60 t cane/ha requires a large quantity of fertilizer with multiple applications, especially for N.

Sugarcane is considered to be an ideal crop to use controlled-release urea (CRU) because of its long growing season, high biomass production, and dense population that makes it difficult to fertilize, especially at mid to late growth stages. A field experiment tested different fertilization rates and timings of CRU application on sugarcane yields in Guangxi, the number one sugarcane-producing province in China.
