Abstract
In order to investigate tillage systems and plant densities effects on corn (Zea mays L.cv.sc704) silage yield and component after harvesting wheat, an experiment was carried out in randomized complete block design in a strip plot. Treatments were arranged with four replications in Agricultural and Natural Resources Research Center Station of Dashte-Naz in Mazandran, Iran, for two years in 2012 and 2013. Tillage systems had three levels: 1. Plow and Disk system (PDS). 2. Disk system (DS). 3. No tillage (NT). Other factor was plant density in four levels (70000, 80000, 90000 and 100000 plant/ha). The results indicated that most silage yield (55.62 ton ha-1) was obtained from Plow and Disk system (PDS) in density of 70000 plants/ha, that had no significant difference effects in comparison with No tillage system (NT) in density of 90000 plants ha-1 with silage yield of 53.39 ton ha-1. The results also indicated that most dry forage yield (18.09 tons ha-1) was obtained from Disk system (PDS) in density of 70000 plants ha-1 that had no significant difference effects in comparison to No tillage system (NT) in density of 90000 plants ha-1 with silage yield of 17.99 ton ha-1. According to results, best treatment was No tillage system (NT) in density of 90000 plants ha-1. Key words: Corn, plant density, silage yeild, tillage system.
