- Effect of irrigation on fruit quality of table olives ( Olea europaea ), cultivar ‘Ascolana tenera’ (1996)
increaseIrrigation increased fruit weight, fruit volume and pulp/pit ratio compared with the control.
TRANSITION TO IRRIGATION OF AN OLD RAIN FED OLIVE ORCHARD IN CROATIA (2011)no changeYield, fruit weight and pith weight were typical for the cultivars and were not affected by irrigation.

A paper is on the positive side when any of its claims here is positive. Claims are grouped by organism, treatment and what was measured or targeted. Claims that compare genotypes are left out; a claim about lacking a nutrient counts the other way round in that nutrient’s question. “Results differ” marks a question where two model reviewers, reading both claims, accepted at least one pair of papers whose results differ.
