Effect of pertigation on leaf area and leaf petiole nutrient contents in Bangalore Blue grapes

摘要

Grape is one of the most important fruit crops and fairly a good source of minerals and vitamins. Bangalore Blue is a variety believed to be a hybrid of Vitis vinifera and Vitis labrusca and popular cultivar grown in parts of South India and in the Southern Dry Region of Karnataka as it is hardy and relatively more tolerant to mildews and adverse climatic conditions. Fertigation permits application of various fertilizer formulations directly at the site of high concentration of active roots and is thus also reported to improve the efficiency of nutrient. Hence, the present study, on fertigaton in Bangalore Blue grapes was undertaken to examine, if drip fertigation could enhance the efficiency of management of nutrient.
