The aim of this project is to improve understanding of nutrient and irrigation management in rambutan, with particular emphasis on management through the fruit filling stage. This should lead to improved yield and fruit quality with more efficient use of fertiliser and irrigation inputs and hence increased profitability.
A new critical range for rambutan soil and leaf nutrition has been developed, and rambutan growers have successfully taken up soil water monitoring principles and practice.
Further work is urgently required on the influence of the environment on rambutan flowering and fruit retention under NT conditions.
