Description
The project evaluates controlled deficit irrigation and reduced fertilization in 'Verna' lemon trees on vigorous rootstock, seeking to extend the harvest, maintain commercial sizes and optimize water and nutritional resources in a semi-arid climate context.
Results
Monitoring the crop's water status, using xylem water potential, has allowed for the detection of stress levels in moderate RDC treatments, corresponding to the degree of irrigation reduction applied. In the short term (one growing season), the treatment with the highest stress level (RDC-60) showed a harvest delay of up to 59 days, representing an attractive option for growers targeting later markets. However, in the long term, the accumulated stress in RDC treatments can reduce the number of final fruit set, thus preventing the desired harvest delay.
