Abstract

In order to investigate the effect of urea different levels and simultaneous cropping of some legumes on agronomic characteristics and total biomass of corn, the study was carried out in the field of agricultural research center of Markazi province in 2013. A experimental design was factorial based on randomized complete block design with three replications. Urea levels including N0= without urea (Control), N1= 75 Kg ha-1 of urea, N2= 150 Kg ha-1 of urea, N3= 225 Kg ha-1 of urea) and simultaneous cropping treatment, (S1= cultivation of corn, S2= cultivation of corn + chickpea, S3= cultivation of corn + cowpea, S4= cultivation of corn + mung bean) were assigned in plots. S. C 704 hybrid was used. Characteristics such as: wet weight of stem + leaves, wide of ear leaf, dry weight of ear + husk, nitrogen Agronomic efficiency, number of legumes grains per m2, harvest index of ear, total biomass of corn + legumes, 1000 grain weight of corn + legumes and amount of nitrogen absorbtion were assessed. Results indicated that the effect of urea levels on the characteristics such as: wet weight of stem + leaves, wide of ear leaf, dry weight of ear + husk, nitrogen Agronomic efficiency, number of legumes grains per m-2, total biomass of corn + legumes and amount of nitrogen absorbtion was significant. Effect of simultaneous cropping treatment on wet weight of stem + leaves, nitrogen Agronomic efficiency, number of legumes grains per m2, total biomass of corn + legumes and amount of nitrogen absorbtion was significant, too. The maximum and minimum of total biomass of corn + legumes (36. 42 and 21. 47 ton ha-1) were obtained in 225 Kg ha-1 urea + Simultaneous cropping of chickpea and corn and non application of urea + Simultaneous cropping of corn and mungbean treatments, respectively.
