A field study was carried out at two sites: village Nazar Killi and Ziam Banda of districts Mardan and Swabi, respectively during Kharif, 2000 to examine the effect of various amendments on the yield of rice crop under saline conditions. The treatments were control, 100% GR, 20 ton FYM ha-1, 2.5 ton pressmud ha-1. 10 ton FYM ha-1 + 1.25 ton pressmud ha-1, 100% GR + 20 ton FYM ha-1, 50% GR + 1.25 ton pressmud ha-1 and 33% GR + 1.25 ton pressmud ha-1 + 10 ton FYM ha-1. All the treatments increased the paddy yield considerably. The most effective treatment noted was the combination of gypsum, pressmud and farmyard manure (94% increase in yield over control) followed by pressmud alone (60%) or in combination with FYM (57%). Of all the treatments, gypsum proved the best in reclaiming the soil with regards to pH and gypsum requirement as it reduced pH and GR at 14-18% and GR 88-100%, respectively.
