Effect of graded levels of magnesium on the yield of hybrid maize in soils of Pudukkottai District, Tamil Nadu, India

Abstract

Field experiments were conducted in the farmer’s holdings with hybrid maize as a test crop during Kharif and Rabi season of 2016-2017 to evaluate the response of maize to soil application of graded levels of magnesium in Pudukkottai district of Tamil Nadu. The experiment was conducted with six treatments replicated five times in a randomized block design. The texture of experimental soil was sandy loam to sandy clay loam. The soil available NPK status fell under low-medium, low to high and low to high categories respectively. The available Mg status was also low to high. The results of the present study revealed that the application of 10 kg Mg ha-1 along with the RDF was found to record the highest grain and stover yield, uptake of Mg and also the available Mg in soil.
