A field study to evaluate the influence of integrated levels of Potassium and Zinc on the green fodder yield of Maize (Zea mays L.) was carried out at Agronomy Section, Agriculture Research Institute Tandojam University during Kharif, 2013. The experiment was laid out in a three replicated randomized complete block design (RCBD), having net plot size 5 x 4m. The treatments consisted of No Potassium + No Zinc (Control), Potassium @40 kg ha-1 and 60 kg ha-1, Zinc @ 5 kg ha-1 and 10 kg ha-1, Potassium @ 40.0 kg ha-1 + Zinc @ 5 kg ha-1, Potassium @ 40 kg ha-1 + Zinc @ 10 kg ha-1, Potassium @ 60.0 kg ha-1 + Zinc @ 5.0 kg ha-1 and Potassium @ 60.0 kg ha-1 + Zinc @ 10 kg ha-1. The integrated application of Potassium significantly effect on maximum plant population, plant height, green leaves plant-1, leaf length, stem girth, biomass weight plant-1and green fodder yield. Potassium @ 40 kg ha-1 + Zinc @ 10 kg ha-1 almost in all the growth and yield traits, particularly green fodder yield (38.1 t ha-1) showing the non-significant differences of above treatments with each other. Hence, the integration of Potassium @ 40 kg ha-1 + Zinc @ 10 kg ha-1 was found most suitable and economical for obtaining an optimum green fodder yield of maize because non-significant differences with Potassium @60 kg ha-1 + Zinc @ 10 kg ha-1 and Zinc @ 5 kg ha-1.
