Influence on different sources of liming materials on nutrient concentration of maize leaf grown in acid soil of Odisha

Abstract

A field experiment was conducted to study the “Influence of different sources of liming materials on nutrient concentration of maize leaf grown in acid soil of Odisha” in the village Bajpur of Khorda district during kharif, 2013. The application of different sources of liming materials increases the nutrient concentration (P, K, Ca, Mg & S) from the 1st stage (30 DAS) to the 3rd stage (90 DAS) except nitrogen because the nitrogen increase from 1st stage to 2nd stage then decreases thereafter from 2nd stage to 3rd stage. The total nutrient concentration in the maize leaf varies between 2.13-2.90 % N, 0.25-0.39 % P, 1.35-2.16 % K, 0.45-0.74 % Ca, 0.48-0.77 % Mg and 0.49-0.33 % S where lowest concentration of all the nutrients were seen in absolute control and highest concentration N was seen in ST @ 0.1 LR, P in PMS @ 0.1 LR+F, K in CS @ 0.2 LR, Ca in CS @ 0.2 LR+F and Mg & S in ST @ 0.2 LR+F. The increasing of nutrient concentration in the maize leaf follows the order N>K>Mg>Ca>P>S. The application of double dose of stromatolite @ 0.2 LR increases the P, Ca, Mg, S concentration & decreases the N, K concentration in all the stages but integration with FYM increases the N, K, Mg, S concentration and decreases the P, Ca concentration. Irrespective of the treatments the application of lone sources of liming materials increases all the nutrients in all the stages but mixed application of liming materials with FYM decreases the N, P, K concentration but increase the Ca, Mg & S concentration.
