Abstract: Abstract Efficient water use remains a major challenge globally. Semi-arid regions of the eastern plains of the state of Uttar Pradesh are no different. With stagnating yields and increased input achieving homogeneity in crop yield remains the only way to increase production. Water being the main drive, its judicious use is to be encouraged. Heterogeneity in water usage resulting in yield heterogeneity has to be quantified. It explains the extent of problem. This research conducted at Samrakalwana village at Allahabad reveals that a 36.12 % heterogeneity in water usage results in wheat yield heterogeneity of 44.04 %. Based upon this, management practices can be recommended to the farmers to minimize yield gap. Water footprints for wheat were obtained. The obtained water footprints for wheat were found to vary between 9844 to 2951 l/Kg. The water productivity ranged from 3.88 to 1.01 Tonnes/m3. This huge variation also explains the large heterogeneity is present in utilizing existing water as a resource at the Samrakalwana village.
