A container model trial was set up on sandy soil with 5 replications to study the nutrient regime of 16 wine grape varieties in a 10 year program starting in 1982 at Kecskemet-Miklostelep in the Institute for Viticulture and Oenology.
Leaf, fruit and wood analysis data and production parameters (fruit and wood weight, frost tolerance) were evaluated every year under identical cultural conditions. Interactions between years, varieties and nutrient elements (N, P, K, Ca, Mg, Zn, B, Fe, Mn) were discussed.
Trials so far have proved the decisive role of variety characters fixed genetically on nutrient uptake and nutrient utilization at given nutrient supply.
