Abstract: 
In order to study the effect of nourishment with chemical bio-fertilizer and manure fertilizers on agrophysiologic characteristics and weed density of maize, an experiment was conducted a split plot based on a randomized complete block design with three replications at Agricultural Research Field Station of Mehran during 2014-2015 cropping season. Nitrogen chemical fertilizer (0, 25, 50, 75 and 100% recommended) was assigned as a main plots and Nitroxin bio-fertilizer (Azospirillum brasilense and Azotobacter chroococcum), manure fertilizer (20ton/ha), co-application of manure and bio-fertilizer and check (without application of biological fertilizer and manure) treatment were arranged as a sub plots. Number of grain per row, number of grain per ear, ear length, plant height, a chlorophyll, b chlorophyll, relative water content, weed density and weed dry weed were significantly affected by main effects of nitrogen and co-application of bio-fertilizer and manure. n this study, interaction effct of nitrogen and coapplication of bio-fertilizer and manure had effect on row er ear, 1000-grain weight, grain yield, biological yield and harvest index. The highest row per ear (20. 6 ear), 1000-grain weight (237. 3 g), grain yield (11900 kg/ha), biological yield (24690 kg/ha) and harvest index (48. 4%) observed in 75 and 100% of nitrogen chemical fertilizer and o-application of bio-fertilizer and manure.
