Abstract

Bud burst, blooming, berry set, verasion and harvest are the key phenological stages of grapevine and identification of these stages is of great economic value to enhance productivity by forecasting the effects of seasonal variations and timely vintage management. Crop modeling is a reliable and robust approach in assessing phenology, crop growth and yield. Chakwal and Rawalpindi/Islamabad districts are emerging as new clusters for commercial viticulture in Pothwar region of Pakistan where key phenological stages and physiological responses need to be identified. Therefore, the present study is designed to evaluate the pheno-physiological responses of table grape cultivars; Kings Ruby, Sugraone, Perlette, and NARC Black at Chakwal and Islamabad using Growing Degree Days (GDD) and STICS dynamic crop models.
