dc.description.abstractA study was conducted to evaluate the nutrient status in different vineyards and its influence on soil fertility, petiole nutrient contents and grape yields during 2019-2020 in Yelburga taluk of Koppal district. Based on the previous year yield data, the thirty vineyards were classified into three groups namely, low yielding vineyards (LYV), medium yielding vineyards (MYV) and high yielding vineyards (HYV). The soil samples were collected before October pruning and after harvest of the crop and petiole samples were collected at full bloom stage after October pruning. The soil pH and EC did not show significant difference among different groups of vineyards. Significantly higher soil organic carbon (7.54 ± 0.34 g kg-1 ) was recorded in HYV group. The available nitrogen (384.57 ± 57.06 kg ha-1 ), phosphorous (75.25 ± 14.22 kg ha-1 ) and potassium status (667.37 ± 59.22 kg ha-1 ) were noticed significantly higher in HYV group. The exchangeable Ca and Mg status were found non significant in soils of all three vineyards group while, the available sulphur was found significantly higher (64.09 ± 18.59 mg kg-1 ) in HYV group. Micronutrient (Fe, Mn, Zn and Cu) content was found significantly higher in HYV group compared to other groups. The nutrient status was recorded higher in soil samples collected after harvest as compared to soil samples collected before October pruning. The petiole nitrogen (1.41 ± 0.21 %), phosphorus (0.48 ± 0.06 %) and potassium (3.07 ± 0.40 %) contents were found significantly higher in HYV group followed by MYV and LYV. The petiole Ca and Mg contents were found non significant while, the sulphur content was found significantly higher (0.25 ± 0.04 %) in HYV. Micronutrient (Fe, Mn, Zn and Cu) content in petiole was found higher in HYV group compared to other groups. The grape yield was recorded significantly higher (33.15 ± 2.69 t ha-1 ) in HYV group compared to MYV (26.25 ± 1.02 t ha-1 ) and LYV group (19.70 ± 1.58 t ha-1 ). The differences in yields of vineyards is depends on nutrient inputs applied, soil fertility status and petiole nutrient concentration etc. Hence, it is important to adopt good nutrient management practices to ensure sustainable grape yields in vineyards.en_US
