In our country wheat is cultivated largely (80 per cent), in irrigated areas whereas, rest in rain-fed. The yield and production in latter part of the country is predominantly controlled by rains during growing season, which usually are erratic. Hence yields are much lower during season of low precipitation.
There are of course three kinds of wheat cultivars, the long duration, the medium and short duration varieties. The wheat yields usually start declining after 20th Nov sowing at the rate of 20 kg per day.
Hence efforts must be made to plant it at optimum time. In cotton areas the sticks are by and large used as fuel in domestic house hold. Big heaps of cotton sticks can be seen along the roadside and in villages.
There is a great need to educate growers as to how much yield is last due to burning of sticks. So as to restores the soil fertility at least 80 per cent sticks may be buried in soil. In order to enhance the decomposition half a bag of urea per acre may be incorporated in the soil after the stick burial.
In view of numerous benefits through the addition of organic matter from cotton sticks, may be made mandatory for each farmer. In case wheat sowing is delayed owing to late maturity of cotton, wheat may be sown in standing crop, if there is low or no incidence of weeds. However in rice tract wheat should be sown on proper time immediately after crop harvest. In rice zone a sizable area must be brought under this season legumes, the chickpeas and lentils. It is of course not so difficult to reap their yields up to 1000 kg per acre, which will bring more finances to the growers as compared to raising wheat.
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.
