Effect of Micro-Nutrients in Growth and Nutrient Uptake of Maize (Zea Mays L.)

Abstract

The pot experiment was conducted in Department of Soil Science and Agricultural Chemistry . Annamalai university to evaluate the response of maize ( Zea mays L.) with conventional ,non – conventional organic source , industrial by-products combined with inorganic fertilizers. The treatments imposed were T_1-Control ( 100 % RDF ) , T_2- 100 % RDF + Municipal Solid Waste Compost @ 5 〖t ha〗^(-1) , T_3- 100 % RDF + Municipal Solid Waste Compost @ 〖10 t ha〗^(-1), T_4 – 100 % RDF + Vermicompost @ 2.5 〖t ha〗^(-1), T_5 – 100 % RDF + Vermicompost @ 5 〖t ha〗^(-1) , T_6-100 % RDF + Bagasse Ash @ 5 〖t ha〗^(-1) , T_7- 100 % RDF + Bagasse Ash @ 10 〖t ha〗^(-1) ,T_8- 100 % RDF + Lignite Flyash @ 5 〖t ha〗^(-1) ,T_9- 100 % RDF + Lignite Flyash @ 10 〖t ha〗^(-1).There were nine treatments combinations replicated thrice in CRD.The uptake of grain in Fe (5.495〖 mg pot〗^(-1)) ,Mn (0.592 〖mg pot〗^(-1)), Zn (0.746 m〖g pot〗^(-1)) and the uptake of grain in Cu (0.118 〖mg pot〗^(-1) ) recorded higher in the treatment ( T_3 ) which received 100 % RDF with Municipal Solid Waste Compost @ 10 tha^(-1).Stover uptake in Fe (44.0〖 mg pot〗^(-1)), Mn (3.25 〖mg pot〗^(-1)) , Zn (0.85 〖mg pot〗^(-1)) and Cu (0.72 〖mg pot〗^(-1)) was recorded highest due to application of 100 % RDF with Vermicompost @ 5 〖t ha〗^(-1) ( T_(5 )).
