Fodder is a necessity for the livestock. As the increased population requires more grain for feed so the land for fodder production is declining with time passage. Some techniques leading to more yields of fodder with lesser leaf area duration have to be developed to overcome the situation. To go through this problem a field experiment to evaluate the influence of different allelopathic chemicals on the growth and yield of forage maize (Zea mays L.) cultivar was conducted at Agronomic Research Area, University of Agriculture Faisalabad during the summer season 2013. Randomized complete block design with factorial arrangement was used. Net plot dimensions were 6 m x 1.8 m. Two fodder maize varieties Pak. Afgoyee and Neelum were tested against foliar application of Brassica, Rice, Sorghum and Moringa extracts as allelopathic substances. Observations regarding plant height (222.87 and 220.46 with averaged 221.66 cm), plant population (14.43 and 14.32 with average value of 14.37), Plant fresh and dry weights, green forage yields (381 and 380.7 with averaged 380.8 g, 23.69 and 22.96 averaged 22.82 g, 62.65 and 62.91 averaged 62.78 t per ha), protein, ash and fiber content were also recorded highest in the treatments subjected to foliar application of moringa leaves extract. The data recorded was analyzed statistically using Fisher's analysis of variance technique and differences among the treatment's means were compared using least significant difference (LSD) test at 5% probability level.
