Abstract:
Data collected were analysed statistically following ANOVA technique and treatment differences were evaluated using LSD test. Pre-cultivation soil analysis revealed a mean soil bulk density value of 2.37 g cm-3 and a value of 17.46 for total porosity. Soil pH showed alkalinity (>pH 7.5) with high values of exchangeable bases and base saturation. Post-cultivation results show that highest yields of rice and millet were obtained from application of 100% gypsum. Yields obtained from gypsum +FYM treatments were, however, statistically similar. Yields from control treatment were consistently low. First millet post-harvest (2011/2012 crop year) soil test showed a reduction in electrical conductivity (ECe) value in all treatment plots except in control. The values of soil pH and sodium adsorption ratio (SAR) reduced after second millet harvest in 2012/2013 cropping season. The study found that soil chemical properties in control treatment did not improve, while combined use of gypsum + FYM + Chiseling appeared most effective in improving the soil conditions for land use sustainability.
