It is a matter of serious concern that out of 11 districts of central India, 9 districts are showing increasing trend in maximum temperature with a rate of 0.01 ˚C to 0.15˚C/year. The regional and seasonal variations in the teperature and rainfall distribution have been the major fac- tors influencing the economy of a region. Livestock rearing is one of the major occupations in India and is making significant contribution to the country GDP. Water shortage can damage field crops anytime throughout the season, especially during the dry season yet the effect on seedling stage has received little attention. Drought tolerant crops, such as sorghum, need to be better exploited to reduce the impact of climate changes. The effects of drought can be mitigated through plant breeding to create cultivars adapted to new climatic conditions and resistant to evolving pests and diseases. The plant varieties with lower water requirements and/or higher resistance to drought could be useful in the areas with limited access to water and thus compensate the losses associated with reduced yields. Different varieties can display various requirements in terms of environmental conditions. In the studies on watering plants, increased emphasis is being placed on understanding reactions to drought, not only in species but also their particular varieties. Drought stress in certain stages of plant growth commonly occurs in many regions of the world. The improvement of tolerance to drought has been a long- lasting principal goal of the majority of breeding programs. Sorghum is a globally cultivated cereal unique due to its tolerance to drought, water logging and saline-alkali infertile soils and high temperature (Taylor, 2003). ![]() It is reported to be one of the main staple food crops for the world’s poorest and food insecure people (Timu et al., 2012). The plant has for a long time been noted to be the most important cereal for human consumption surpassed only by maize, wheat, rice and barley (Dicko et al., 2006 Akram et al., 2007). ![]() Sorghum is one of the most important drought tolerant crops and is often referred to as the camel of the plant kingdom (Fetene et al., 2011). Broom sorghum on the other hand is for making brooms while sweet and grass sorghum is used to make sweetener syrup and green feed (U.S Grain Council, 2010). Grain sorghum is mainly used as a principal food in tropical areas and often used as raw material for alcoholic beverages, sweets and glucose. grain, sweet, broom sorghum or grass sorghum. It is a member of the grass family graminea and can be categorized into four groups by application, i.e. The crop is a self- pollinating plant and its drought tolerance is higher than that of corn. Sorghum is produced throughout the tropical, semi-tropical and arid regions of the world. The oldest cultivation records date back to 3000 B.C.
