A field experiment was conducted to determine the growth, yield and quality performance of spring maize treated with different rate and source of organic materials i.e. poultry manure (PM) and farmyard manure (FYM) in 2006 under agro-ecological conditions of Faisalabad. The treatments included were 10, 15, 20, 25 and 30 t per ha FYM and 4, 6, 8, 10 and 12 t per ha PM. The results indicated that grain yield of 5.6 t per ha was recorded in plots added with 12 t per ha PM and it was statistically same as obtained with 10 t per ha PM. The increase in yield was attributed to increase in cob length, cob diameter and number of grains per cob. Grain protein percentage (8.15) was also maximum where 12 t per ha PM was applied. Effects of different treatments on growth and yield parameters of maize are discussed.
