Still, the per hectare yield remained low compared to what is customary for the\nviticultural zone. The vines were nutritionally deficient to begin with, due to a lack of\nfunding during the critical years 2014\u20132017. Nevertheless, grape quality seems excellent,\nwhich results in the harvest of the entire vineyard being vinified as Thymari Petras, a limited\nedition of approximately 1200 bottles produced by the Petrakopoulos winery. The wine\nretails for around \u20ac45 per bottle.<\/p>\n<p>&nbsp;<\/p>\n<p>As far as the Robola experimental vineyard in the Omala region, the main findings are:<\/p>\n<ul>\n<li>In terms of ampelographic descriptors, it seems that the four Robola biotypes V<sub>1<\/sub>\u2013V<sub>4<\/sub>are more similar to each other than to the typical Robola preserved at the national germplasm\ncollection in Athens. We recommend further analysis of their genetic affinity with\nmolecular methods.<\/li>\n<li>The highest yielding combinations of rootstock and scion are 1103P-V<sub>2<\/sub>, 1103P-V<sub>1<\/sub> and R110-V<sub>1<\/sub>. Biotype V<sub>1<\/sub> seems indifferent to rootstock as it performed similarly on both 1103P and R110 rootstocks.<\/li>\n<li>Ongoing research at our lab examines more ampelographic descriptors related to mature\nleaf and berry characteristics.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>As far as the experimental vineyard at the Ionian University in Argostoli, the main findings\nare:<\/p>\n<ul>\n<li>After 10 years of No till treatment, several soil properties improved\u2014albeit marginally\u2014relative to the Till or \u201cconventional\u201d treatment. Specifically, in the No till treatment, organic matter is marginally higher for both soil depths examined.<\/li>\n<li>The No till treatment holds an advantage as far as nutrients: Exchangeable potassium, plant available phosphorus, and total nitrogen. This advantage is consistent for both depths examined.<\/li>\n<li>The No till treatment holds an advantage as far as microbial biomass nitrogen and\nphosphorus in the surface layer.<\/li>\n<li>The activities of enzymes \u03b2-glucosidase and L-asparaginase are higher in the surface\nlayer of the Till treatment, possibly due to the incorporation of fresh organic residue.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>The detailed results from both experimental vineyards were presented at the 2022 meeting of\nthe Soil Science Society of America and the American Society of Agronomy:<\/p>\n<p>Katsalirou, E., A.
