Crops and varieties suitable <strong>for</strong>calcareous soil have been given in table -21.Apply the nutrients as per the dose recommended <strong>for</strong> the crops.Integration of organic manures with chemical fertilizer in 50:50 ratio to meet out thenitrogen requirement of the crop/cropping systems helps in mitigating the ill effect ofexcess carbonates in soil.In calcareous soils crop often suffers sulphur deficiency, application of 50 kg S/ha isrecommended <strong>for</strong> maize, Napier bajra hybrid, Guinea grass and Setaria <strong>for</strong> higherbiomass production and quality improvement.Apply the micronutrients like Zn, Cu, Mn and Fe depending upon the soil testrecommendation to manage the lime induced micronutrients deficiency limiting theproductivity of the crops.Output and economics: The oat variety OL-125 produces higher biomass and net profitin comparison to OL-189 and, Kent grown in calcareous soil. In light textured calcareoussoil, the deficiency of Mn causes poor growth of oats, application of 10 kg /ha Mn hasshown potential <strong>for</strong> 8.7- 44.3% increase in the <strong>for</strong>age yield. The application of sulphur @50 kg/ha is beneficial <strong>for</strong> improvement in <strong>for</strong>age yield of maize, Napier bajra hybrid,guinea grass and Setaria.Specific benefits : Increased availability of quality <strong>for</strong>age <strong>for</strong> sustained livelihood inlow productive areas, selection of tolerant crops ensures efficient utilization of natural<strong>Forage</strong> <strong>Production</strong> <strong>Technology</strong> <strong>for</strong> <strong>Arable</strong> <strong>Lands</strong>39
