Foliar Diagnosis of Nutrient Deficiencies in Mauritius Sugar Cane I. Changes in Optimum Leaf Nitrogen with Ecological Conditions
Published online by Cambridge University Press: 03 October 2008
Summary
The response of six cane varieties to nitrogen fertilization (0, 70 and 140 kg. N/ha.) has been studied. Results of three ratoon crops from 23 trials on representative sites throughout Mauritius indicate that optimum fertilization is around 70 kg. N/ha. Three levels for optimum nitrogen in the third leaf blade have been established, namely 1·93, 2·05 and 2·22 per cent corresponding roughly to the sub-humid, humid and super-humid areas of Mauritius.
