The experiment was laid out in split plot design with three land configuration practices as main plots and four different combinations of an organic and inorganic source of nutrients as subplots replicated thrice. The results showed that, significantly higher seed cotton yield (2834 kg ha -1 ) were recorded with land configuration practice of Ridges and Furrow method in conjunction with application of 90:45:45 NPK kg ha -1 (50% N through organic) when compared to Broad Bed and Furrow method and Flat Bed methods and their respective combination with different Original Research Article
