Abstract
A study was conducted to assess the fertility status of Kanwara minor lift canal command area using Nutrient Index values of different soil parameters under study in 2019-20. A systematic set of two hundred and eleven georeferenced soil samples were collected and analysed following the standard sampling and analytical procedure. The analysed values of different parameters were categorized in low, medium and high and further used in determination of the nutrient index. NI value of soil organic carbon was 1.16, 1.00 for available N, 1.47 for available P and 2.55 for available K respectively. Regarding the fertility class based on Nutrient Index values it was deficient in organic carbon, available N and available P while, sufficient in soil available K. This requires immediate attention towards the management of nutrients to restore the soil fertility and sustain crop productivity.
