Taluk wise secondary data on the soil parameters viz., pH, EC, OC, P, K, Zn, Fe, Mn and B content for Bangalore Rural, Bangalore Urban and Ramanagaram districts were collected for the period 2007-2013. Per centdeficiency in Zn, Cu, Fe, Mn and B from 1998-2013 were collected for all districts of Karnataka. The data on productivity of paddy and ragi from 1998-2009 were collected for major growing districts of Karnataka. The descriptive statistics showed that soils of Nelamangala taluk had highest pH and Bangalore north had highest in rest of the nutrients. P and Fe were maximum in Magadi and Bangalore East. Correlation among nutrients showed that P, K, Zn, Cu, Mn, Fe and B were positively related with pH. Further, OC and EC were positively significantly related with P, K, Zn, Cu and Mn. With respect to deficiency in Fe, Mn and B positive significant trend were noticed in majority of the districts. While, deficiency in Zn and Cu were noticed in few of the districts. A multiple regression analysis on availability of Zn and B on the productivity of paddy and ragi showed that these nutrients were insufficient for enrichment of the soil.ennullSTATISTICAL ANALYSIS OF NUTRIENT STATUS IN SOILS OF KARNATAKAThesis
