A studywas conducted to study the influence of secondary and micro nutrients status of soils on grape yield of vineyards during the year 2019-20 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 collected after harvest of crop recorded slight increase in the exchangeable Ca and Mg content compared to the soil samples collected before October pruning. The HYV [11.16± 2.61 and 12.08±2.76 c mol (p+) kg-1] soils recorded higher calcium content compared to other groups in both the sampling seasons respectively. HYV [6.81± 1.26 and 6.88 ± 1.19 c mol (p+) kg-1] recorded highest exchangeable Mg content compared to other two groups in both the sampling seasons respectively. The sulphur content in group HYV was significantly higher (51.67 ± 16.46 and 64.09 ± 18.59mg kg-1) as compared to the other groups at before October pruning and at after harvest, respectively. Distribution of micronutrients in soil samples collected before October pruning and after harvest were found in the order Mn > Fe > Zn > Cu. Vineyard soil sample showed medium to high content of micronutrients. The concentration of DTPA extractable micronutrients among three groups of vineyards differed significantly. The differences in yields of vineyards is depends on soil fertility status. Hence, it is important to adopt good nutrient management practices to ensure sustainable grape yields in vineyards.
