The effect of deep and shallow tillage and fertilizer treatments i.e., recommended dose of fertilizer (RF), farm yard manure (FYM) and recommended dose of fertilizer plus farmyard manure (RF+FYM) on maize fodder yield was studied under rainfed conditions of Pakistan. It was observed that the emergence count m-2, maize fodder biomass, plant height, number of leaves per plant and maize fodder yield enhanced, with the application of RF+FYM. However, the effect of FYM+RF and recommended dose of fertilizer was statistically non-significant and on average basis RF+FYM treatment produced higher green fodder (19971.5 kg per ha) than fodder yield of 18349.1 kg per ha produced by applying recommended dose of fertilizer. However, green fodder yield produced with these two fertilizer treatments were significantly higher than that of the FYM and control treatments. The FYM treatment gave lowest fodder yield (16997 kg per ha) and was significantly lower than the fodder yield (17278.7 kg per ha) obtained in control treatment. The nutrient availability in RF+FYM treatment significantly increased the biomass production, however, application of FYM promoted the weed infestation that reduced the green fodder yield of maize, but it improved the overall forage yield as recorded in RF+FYM treatment. The effect of deep tillage on maize fodder yield was non-significant.
