Wheat feed about 2.5 billion poor people (living on <2 $/day). Pakistan is predominately an agricultural country and over 60% of its economy is Agri-based. In Pakistan, 85% wheat area is irrigated, and 15% area is rain-fed. The Average yield of the irrigated area has been assessed around 30-33 minds/acre, whereas average Yield in rain-fed area is around 12-15 minds/acre. The Prime Minister of Pakistan approved agenda and allowed Ministry of National Food Security & Research (M/o NFS&R) to work on increasing productivity and profitability of wheat and develop sustainable mechanism for improved wheat production. Integrated Nutrients Management involved collective use of organic and inorganic fertilisers so that both soil fertility and productivity can be achieved with single shot. Objectives: Coordinated research to develop climate resilient, high yielding, disease resistant, heat & drought tolerant wheat varieties as well as innovative resource conserving crop production & protection technologies.
