Abstract:
India is gifted with advantages like soil variation and different types of climate. Hence This heterogeneous climatic condition has formed potential area for grapes cultivation zones. In Karnataka, its cultivation is seen in Krishna valley of northern parts and Nandi valley of southern parts of the state. Almost all the areas of major grapes-growing soils, fall under dry climatic conditions in Karnataka and contribute significantly for the state economy. Karnataka is the second largest grapes producing state in India and Devanahalli sub-division of Bangalore Rural district of Karnataka is well known area for production of Bangalore Blue variety which is predominantly grown in this region. Soil physical, morphological and fertility parameters were studied. Soils of Devanahalli vineyard was coarser in texture in surface and fine comparatively in sub-surface, The surface horizon was reddish brown and dark reddish brown in colour when dry and moist condition, respectively with a thickness of 11 cm. Soil reaction was slightly acid to neutral in soil water suspension ranging from 6.28 to 6.49 pH. There was no harmful effects of salts (EC) noticed in the pedon (0.07 to 0.11 dS m-1). Soil reaction was slightly acid to neutral in soil water suspension ranging from 6.28 to 6.49 pH. There was no harmful effects of salts (EC) noticed in the pedon (0.07 to 0.11 dS m-1). Available Cu, Fe, Mn, Zn, and B in the soil varied from 1.90-21.68, 9.1-18.98, 25.6-28.42, 1.2-5.12 and 1.71-5.18 mg kg-1 soil, respectively in fertility samples.
