Sugar Beet Cultivation in India: Prospects for Bio-Ethanol Production and Value-Added Co-Products.

Sugar beet is an important crop in the advent of COVID 19 as it has a high potential for ethanol production in less growth span. The life cycle of this crop is of five to six months with a root yield of 60-80 t ha and sugar content of 15-17%. Sugar beet is known as a temperate crop of short duration grown in the month of September to October and harvested in April and May, but successful efforts have been made in establishing this crop for Indian agro-climatic conditions. India stands to gain from capitalizing on the potential of sugar beet for sugar, ethanol, and fodder. It offers the increment in the farmer's income especially hill farmers with respect to seed production of this crop in India The crop has been bestowed with a natural endowment of reclaiming saline soils which will help in cultivating the Indian saline areas. The crop is full of carbohydrates content which is being used for multiple purposes giving value addition to the crop. The green top and, wet and dry pulp are a good source of fodder material for lactating animals like cattle. Beet pulp is another good source as silage feed and as an adhesive in beauty products as well as in printing ink. An amount of 5250 L of ethanol per hectare crop can be produced. Due to 30% galacturonic acid content, the dry beet pulp can also be used as a source of Vitamin C. Lactic acid is also being produced from the juice of sugar beet through fermentation. The pectin content of this crop is useful in paper and board manufacturing industries as a raw material and also in dishwashing detergents and leather production. The fiber content works as dietary fibers which are used in meat and baking industries as important ingredients in food commodities. The vinasse produced as an industrial by-product is useful as a fertilizer. Sugar beet tails and other parts have also been used in biogas production in some countries. Intercropping of this crop with other crops is an added benefit of this crop. New prospects are also available for this crop in pharmaceutical industries and material sciences in times to come.
