Abstract

                                A pot culture study with sixteen treatments (combination of two levels of lime, two levels of KO and four levels of magnasium) was conducted with CO 7 ragi (Eleualhe Coracana Gaertn.) as the test crop. The results indicated that application of magnesium at the rate 50 kg Mg/ha was the optimum in increasing the yield. Ragi yield was increased by 15.14 per cent. However quadratic In both the soils liming depressed the yield Under high calcium content in the soil, lower availability of magnasium and phosphorus was observed. Potassium did not influence the ragi yield. Top/rost ratio indicated that root was affected more intensely by magnesium than the tops Soil variations in their response to application of magnesium, lime and potassium ware significant. Titukkal soil was better than Doddabetta soil.
