Field experiment was conducted at organic research farm Karguan Ji, Institute of Agricultural Sciences, Bundelkhand University Jhansi (UP) during rabi season. The experiment was laid out in randomized block design comprised three levels of FYM (0, 10and 20t/ha) and three levels of Zinc (0,5 and 10 kg/ha) with three replications. The application of FYM and Zinc obtained significantly higher values in respect to growth,yield attributes and yieldof maize in all the treatments, over control.The maximum values and increased percentage were recorded in respect to plant height, no. of grains/cob, grains weight/cob, weight/cob, 100 seed weight, biological yield, stover yield and grain yield of 146.03cm and 12.35%, 288.66 and 7.4%, 96.86g and 12.36%, 92.30g and 13.72%, 20.1g and 5.0%, 150.33 q/ha and 33.67%, 107.16 q/ha and 33.3%, 42.86 q/ha and 33.4% with T8 treatment respectively,over control, followed by T7, T5 and T2 treatments. All the treatments were found superior in respect to all parameters, over control, while T8 treatment was proved most superior among the treatments. The data in respect of harvest index statistically found non significant. The lowest values regarding growth, yield attributes and yield at lower level of10 t/ha FYM along with 5 kg/ha Zinc application in the study.The soil samples were found neutral in reaction, normal in EC, low in organic carbon, low in available nitrogen, medium in available phosphorous& zinc and high in available potassium.

Key words : Biological yield, FYM, Grain yield, Harvest index, Stover yield, Zinc.
