Land development is one of the prime components of sustainable farming. Unevenness of agricultural fields leads to the in-efficient use of irrigation water, which in turn reduces the yield and farm income. Levelling index, which is a dynamic factor, determines the quality and accuracy of land levelling. Land development/levelling is having enormous impact on moisture storage and distribution in the field both spatially and temporally, crop growth, yields and irrigation water saving. Therefore, it is imperative to study the impact of levelling indices on soil moisture distribution in fields. An experiment was conducted in the research farms of Irrigation Water Management Research Center (IWMRC), Belvatagi, University of Agricultural Sciences (UAS) Dharwad during Rabi 2018 to investigate the effect of land levelling indices on soil moisture distribution in Cotton fields. The results indicated spatial variability with respect to levelling indices and soil moisture in the same fields with average LI ranging from 1.57 cm to 3.50 cm and average soil moisture ranging from 28.63 % to 31.87 %. Also, it was found that lower the LIs higher the soil moisture i.e. soil moisture increased with the better quality of land leveling irrespective of the cotton varieties. Soil moisture distribution variability can be reduced by better quality of land leveling.
