Description

A photo taken by Nava Thompson of grapes in a vineyard in Tontitown Arkansas. I love the look of beautfiul grapes on the vine in the sun with all the various colors of grapes...............................Recently planted vineyard in Medanos, Argentina.The quest for vineyard efficiency has produced a bewildering range of systems and techniques in recent years. Due to the often much more fertile New World growing conditions, attention has focussed heavily on managing the vine's more vigorous growth. Innovation in palissage (training of the vine, usually along a trellis, and often referred to as "canopy management") and pruning and thinning methods (which aim to optimize the Leaf Area/Fruit (LA/F) ratio relative to a vineyard's microclimate) have largely replaced more general, traditional concepts like "yield per unit area" in favor of "maximizing yield of desired quality". Many of these new techniques have since been adopted in place of traditional practice in the more progressive of the so-called "Old World" vineyards.............................................Other recent practices include spraying water on vines to protect them from sub-zero temperatures (aspersion), new grafting techniques, soil slotting, and mechanical harvesting. Such techniques have made possible the development of wine industries in New World countries such as Canada. Today there is increasing interest in developing organic, ecologically sensitive and sustainable vineyards. Biodynamics has become increasingly popular in viticulture. The use of drip irrigation in recent years has expanded vineyards into areas which were previously unplantable........vineyard using modern spacing and trellising methodsFor well over half a century Cornell University, the University of California, Davis, and California State University, Fresno, among others, have been conducting scientific experiments to improve viticulture and educating practitioners. The research includes developing improved grape varieties and investigating pest control. The International Grape Genome Program is a multi-national effort to discover a genetic means to improving quality, increasing yield and providing a "natural" resistance to pests.............The implementation of mechanical harvesting is often stimulated by changes in labor laws, labor shortages, and bureaucratic complications. It can be expensive to hire labor for short periods of time, which does not square well with the need to reduce production costs and harvest quickly, often at night. However, very small vineyards, incompatible widths between rows of grape vines and steep terrain hinder the employment of machine harvesting even more than the resistance of traditional views which reject such harvesting.
