Increasing the yield of Nebbiolo grapevines grown in acid soils: a comparison of different techniques

The detrimental effect of soil acidity on the performance vines can be attributed to both P deficiency and Al toxicity stresses. This study aimed investigate different agronomical techniques applied in a vineyard Nebbiolo solve problem low productivity due pH. liming, phosphorus fertilization pre-bloom shoot trimming yield bud fruitfulness was followed over period 3 years. Moreover, last year grape analyses were performed assess treatments’ quality. Results confirmed that it is possible alleviate part Overall, trimming, fertilization, combination these two treatments have been most effective options. Regarding differences between treatments, only fertilisation significantly affected yields comparison untreated. Little or no has observed among terms composition at harvest.
