Response of agronomic traits of forage corn to simultaneous cropping with legumes, nitrogen levels and cultivator application

In order to Response of agronomic traits of forage corn to simultaneous cropping with legumes, nitrogen levels and cultivator application. A factorial randomized complete block design with three replications was used. Urea manure levels [N0= without urea (Control), N1= 150 Kg ha-1 of urea, N2= 300 Kg ha-1 of urea) and simultaneous cropping treatment, (S1= cultivation of corn, S2= cultivation of corn + cultivator application, S3= cultivation of corn + cultivator application + soybean, S4= cultivation of corn + cultivator application + cowpea, S5= cultivation of corn + cultivator application + alfalfa) were assigned in plots. In this study, traits such as stem diameter, height of earing, number of ear, wet weight of ear, number of grain per m-2, harvest index, biological yield, wet weight of stem and leaf and surface of ear leaf were evaluated. The result have shown that the interaction effect of urea levels and simultaneous cropping + cultivator application treatment was significant on stem diameter, height of earing, wet weight of ear, number of grain per m-2, harvest index, biological yield and wet weight of stem and leaf. The highest and lowest of biological yield (18.13 and 9.60 ton ha-1) were obtained with the cultivation of corn + cowpea + 150 Kg ha-1 of urea + cultivator application and cultivation of corn + cowpea + cultivator application + 0 Kg ha-1 of urea manure, respectively
