Therefore, these practices should be recommended to sugarcane growers for sustainability of the cropping system while maintaining the soil resource base.

Because of urbanization infrastructural expansion, industrial growth, and land degradation losses due to rapid erosion and secondary salinization, the arable land area has been shrinking (Lal, 2013). Generally, the soil types of Rajasthan are sandy, saline, alkaline, and calcareous soils and were commonly called clay, loamy, and black lava soils. Groundwater level is very low because the annual rainfall is approximately 360 mm and the ground water level very deep. Water is available at depths of 100 to 61 meters. The soil of the Rajasthan region is classified as Aridisols, Alfisols, Entisol, Inceptisols and Vertisol according to the USDA Land Division program (Chiroma et al., 2014). The capital of Rajasthan is the state of Jaipur, located between 26˚55′10ʺ N and 75˚47′16ʺ E. Jaipur has an average height of 1414 feet from sea level and Jaipur 11,152 km 2 .
