Importance of Cacti (Opuntia sp) and its role in dryland management

Abstract

Introduction of drought tolerant plant species and adoption of soil and water conservation are regarded as component of management strategy for arid lands. Cacti and platyopuntias are CAM plants with ability to withstand long periods of droughts and able to produce large quantities of fodder during periods of favourable rainfall. Nutritionally cactus is low in crude protein, fibre phosphorus and sodium. Opuntias are high in moisture (85-90%), soluble carbohydrates vitamin A (29 µg/100g carotenoids), Ca (1.4%) and ash (20%). By appropriate supplementation and feed combination the protein deficiency can be overcome. The studies indicate that Opuntias can be successfully integrated in rangelands. With high water and rainfall use efficiency cactus form a good component in the arid ecosystem. Once established, the cactus can either be subjected to controlled grazing or stall feeding. The adaptability studies conducted shows that the crop can very well come up in the arid region of India.Not Available
