Description

This data was collected from a field experiment conducted during two consecutive seasons (2013/14 and 2014/15) at the Agricultural Research Council, Vegetables and Ornamental Plants, Pretoria, South Africa. The experiment had a 2×2×2 factorial design; factors were irrigation regimes (W1- well-watered regime; W2- supplemental regime), soil fertilisation [F1 - 100% N, P, and K application; F2 (control) - 0% N, P, and K application], and vine harvest (H1 - no vine harvesting; H2 - vine harvesting every 4 weeks). W1 means keeping soil water content (SWC) above 30% of plant available water and W2 was supplemental irrigation; if it did not rain for four weeks and soil water content reached a depletion of 80%, we irrigated back to 50% of plant available water
