The demand for high yield and fruit quality increases along with world population growth, demand for healthy fresh fruit, increased labour cost, and competitive land use. Implementation of precision horticulture relies heavily on sensors and systems, playing an increasingly important role in today’s horticultural production systems, regardless of operation size, commodity or management approach. This issue is providing current aspects and future perspectives of advances in sensing technology, various types of sensors that have been developed commercially and are becoming available in precision horticulture. It aims to provide a comprehensive coverage of the current trends on optical sensors, potential techniques for efficient, rapid and non-invasive detection of yield, stress, fruit size and quality. Special attention is given to new directions of sensor based extracted plant information and its relation with tree and fruit physiology.
