dc.description.abstractNutrients play a number of crucial roles towards better vine growth, yield and quality attributes of berries. Soil and petiole nutrient analysis helps in the determination of optimum nutrient recommendation for optimum yield and quality. Keeping these facts in view, a study was conducted to assess the soil and petiole nutrient status of different red and white wine varieties during summer and winter season in Doddaballapura taluk. The mean soil nitrogen (250.88 kg ha-1), phosphorus (32.92 kg ha-1), potassium (180.76 kg ha-1), Magnesium (3.28 meq/100g) and zinc (1.74 ppm) contents were highest in white wine orchards while calcium (5.55 meq/100g), sulphur (19.99 ppm), Copper (7.27 ppm), manganese (45.55 ppm) and iron (0.97 ppm) contents were more in red wine soil samples during winter season. In summer season, the maximum petiole N (1.63 %), Ca (2.07 %), Mg (0.67 %) and S (0.33 %) contents were noticed in red wine grapes while P (0.41 %) and K (1.61 %) contents recorded more in white wine grapes. Zn (92.32 ppm) and Mn (83.67 ppm) contents were more in red wine grape petioles whereas Cu (17.28 ppm) and Fe (75.12 ppm) concentrations were higher in white wine grape petioles during winter season. Between red and white wine grape varieties, the maximum mean length of shoots (77.25 cm), number of new shoots (20.75) and bunch weight (326.87 g) were noticed in red wine grapes. However, the maximum mean number of inflorescence (after thinning - 14.75), average yield (4.02 kg vine-1) and total yield (3810.00 kg acre-1) were recorded in white wine grapes. Red wine grapes recorded the lowest average yield (2.37 kg vine-1) and total yield (2,127.50 kg acre-1) with the maximum TSS (22.03 0brix), pH (3.43), firmness (1.52 N) and minimum titratable acidity (0.17 %). Correlation studies revealed that potassium and zinc positively correlated with high TSS and nitrogen with acidity.en_US
