Effect of Nano Fertilizers and Various Nutrient Sources on Growth Parameters of Maize (Zea mays L.)

Abstract

A field investigation was carried out during kharif season at Crop Research Centre-1, School of Agriculture, ITM University to study the effects of nano fertilizers and various nutrient sources on the growth and growth parameters of maize. The experiment was laid out in a randomized block design with three replications. The experiment consists of twelve treatments viz., T1- Control, T2 - 100 % RDF through chemical fertilizer (120:60:30 NPK kg ha-1), T3 - 100 % RDF through chemical fertilizer + nano fertilizer @ 1 g l-1 of water, T4 -100 % RDF through chemical fertilizer + nano fertilizer @ 1.5 g l-1 of water, T5- 100 % RDF through chemical fertilizer + nano fertilizer @ 2 g l-1 of water, T6 - 100 % RDF through chemical fertilizer + nano fertilizer @ 2.5 g l-1 of water, T7-125 % RDF through chemical fertilizer, T8- 75% chemical fertilizer + 25% vermicompost, T9- 75% chemical fertilizer + 25% vermicompost + nano fertilizer @ 1 g l-1 of water, T10 - 75% chemical fertilizer + 25% vermicompost + nano fertilizer @ 1.5 g l-1 of water, T11- 75% chemical fertilizer + 25% vermicompost + nano fertilizer @ 2 g l-1 of water, T12 - 75% chemical fertilizer + 25% vermicompost + nano fertilizer @ 2.5 g l-1 of water. The results of the experiment revealed that application 75% chemical fertilizer + 25% vermicompost + nano fertilizer @ 1g l-1 of water significantly influenced the growth attributes. This treatment recorded higher values of growth parameters like plant height of green leaves, leaf area per plant, dry matter accumulation, Leaf area index, Crop growth rate, and Relative growth rate The lowest values were recorded in the control.
