Abstract: The population of India is likely to reach by 1.4 billion in 2025 with 42.5% as urban. With per capita land availability <3 ha and net availability of cereals and pulses < 450 g d-1, India is facing challenge in coping up with the national food security and environmental sustainability. Western Uttar Pradesh registered a high agricultural growth during the second wave of ‘Green Revolution’ in 1980s. However, rapid urbanization and developmental processes are increasingly in conflict with other forms of land use, especially agriculture. This study addresses the productivity trends and soil fertility status of Saharanpur district of western Uttar Pradesh.The Soil fertility has direct implication on the agricultural production scenario of the region. Soil samples from 16 villages covering 8 Blocks were collected during the period of 2016-17. Results showed that soil organic carbon content was 72-54%. However, entire district and area of 64%, 57% and 54% were low under nitrogen, phosphorus and potassium availability. Micronutrient in general, was low except copper, which indicated that 48% of the area was under low availability of micronutrients. A methodology was developed to enhance the individual nutrient status. The integrated nutrient status showed that the 48% of area had multi-nutrient deficiencies and fell under higher priority zone of UP that immediate nutrient management is needed for region to meet which indicated requirement of nutrients.Potential yields of major crops of the district were computed and current yields were obtained through field survey in selected land units and other collateral data. Yield gaps (potential-current) ranged 3.87-6.64, 2.85-4.89 and 30 t/ha in rice, wheat and sugarcane for a majority of land units. A few agri-technological levels were tested for the fertilizer inputs required to bridge yield gaps in rice, wheat and sugarcane in selected land units. It is argued that augmenting the production through assessment of biophysical potential of a district can ensure food security and sustainability of the system.
