Wheat in Pakistan is grown under different agro-ecological zones. In irrigated areas wheat is planted after cotton, rice and sugarcane. In rain fed areas wheat is grown in sequence with maize, sorghum, pearl millet and after fallow especially in low rainfall zone. In the Punjab region of India and Pakistan, as well as North China, irrigation has been a major contributor to increased grain output. Use of fertilizer and semi-dwarf varieties in developing countries, has increased yields per hectare. Fertilizer and breeding technique improves its yield. Crop rotation with canola crop boosts yield by 25 %. Globally wheat is a leading source of vegetable protein in human food and has higher protein content than other major cereals. Wheat grain is staple food used to make flour for leavened, flat and streamed bread, biscuit, cookies, cake, breakfast etc. Wheat is used in a secondary capacity in some markets as a feed for livestock.
