Wheat requires moderate temperatures (maximum 20-23 degrees Celsius and minimum 4-5 degrees Celsius) during sowing season and light rains in January for growth. High temperature and no rains lead to improper growth of the crop, early ripening and damages formation of grain. It thrives best in well-drained loamy soil. Wheat is grown extensively in USA, Canada, Argentina, Russia, Ukraine, Australia and India. In India it is grown in winter.
