Abstract: Field experiment was conducted at Zonal Agricultural Research Station, UAS, GKVK, Bengaluru during kharif 2017 to study the Effect of different levels of seed rate, nitrogen and zinc on yield and quality of fodder maize (Zea mays L.). There were 18 treatment combinations involving 3 levels of seed rate (50, 75 and 100 kg ha-1), 3 nitrogen levels (100, 125 and 150 kg ha-1) and 2 zinc levels (0 and 10 kg ha-1). The experiment was laid out in a FRCBD, replicated thrice. The results revealed that, seed rate of 75 kg ha-1 recorded significantly higher green fodder yield (34.29 t ha-1), Crude protein yield (0.89 t ha-1 and crude fiber yield (3.67 t ha-1) over 50 kg ha-1 (29.58, 0.72 and 3.10 t ha-1, respectively) and was on par with seed rate 100 kg ha-1 (32.50, 0.80 and 3.58 t ha-1, respectively). Application of 150 kg nitrogen ha-1 resulted significantly higher green fodder yield (34.56 t ha-1), crude protein content (8.95 %) and lower crude fiber content (32.05 %) over nitrogen at 100 kg ha-1 (29.14 t ha-1, 7.52 and 35.46 %, respectively). 10 kg zinc ha-1 recorded significantly higher green fodder yield (33.07 t ha-1), crude protein content (8.50 %) and lower crude fiber content (33.12 %) over no zinc.
