Fertilizer management plays an important role in obtaining satisfactory yields from maize. In addition, fertilizer management is essential for achieving sustainable agriculture and protecting the environment. The reported experiment was conducted in the summers of 2013-2014 in the Aghili region in the north of Khuzestan Province. The experiment was conducted as four replicates using split plots randomized complete block design (RCBD). The experiments consisted of four levels (25, 50, 75, and 100 %) of chemical fertilizers nitrogen (urea) and phosphorus (Triple superphosphate) and level of bio fertilizers (Control and 100 %), which were the main factors. The sub factor was three types of maize hybrids, which were single cross 704, single cross 701(SLD45/1/2-1× MO17), and single cross Mobin (SLD 45/1/2-1× SLH 2/29/14/2-4/1).The highest yields were obtained from the single cross 704 with 25% chemical and 100% bio-fertilizers (12,875 kg/ha) and it was followed by single cross 704 with 50% chemical and 100% bio-fertilizers (12,385 kg/ha), while the lowest yield was obtained from the single cross Mobin with 25% chemical and 100% bio fertilizers (10,215 kg/ha). The yield and component yield differences were observed between treatments so that the grain yield and biological yield as well as number of grains per row were significant at the 1% level and there were no significant differences between the other components.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
