Abstract: Field experiment on Effect of different levels of seed rate, nitrogen and zinc on yield and quality of fodder maize (Zea mays L.) was conducted at Zonal Agricultural Research Station, UAS, GKVK, Bengaluru during kharif 2017. 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 dry matter accumulation (104.32 g plant-1) and green fodder yield of 34.29 t ha-1 when compared to seed rate of 50 kg ha-1 (98.60 g plant-1 and 29.58 t ha-1 of dry matter accumulation and green fodder yield respectively), and was on par with seed rate 100 kg ha-1 (102.75 g plant-1and 32.50 t ha-1 of dry matter accumulation and green fodder yield respectively). Application of 150 kg nitrogen ha-1 resulted significantly higher dry matter accumulation of 107.87 g plant-1 and green fodder yield (34.56 t ha-1) over nitrogen at 100 kg ha-1 and 125 nitrogen per ha. Application of 10 kg zinc ha-1 recorded significantly higher dry matter accumulation of 103.69 g plant-1 and green fodder yield (33.07 t ha-1) over no zinc application (30.78 t ha-1).
