Pg. 30-31 Monitor Tree Nitrogen Status to Maintain Lychee Yields

Lychee (litchi) seedlings were grown in sand culture with different levels of applied N (nitrogen) to determine the optimum concentration of N in the plant for growth and potential yield. Differences in shoot growth above and below 1.2% N in leaves were not reflected in large differences in leaf colour. These results suggest that productivity will be affected long before leaves yellow. Growers need to monitor the levels of Nin their orchards and maintain them above 1.2% for optimum production.
