Determining Bush Density Amount, Yield and Zea Maize Seed Moisture in Different Tillage Methods

Tillage or preparing land operation is of first suitable farm management factor that cause preparing wide environment from mineral resources, better water penetration into soil and lead to soil penetration and its change.This investigation was done in a loamy soil in order to survey and evaluation of bush density condition, yield and zea maize seed amount in different tillage methods in north of Shoush city. In this investigation, effects of 3 different methods that formed for preparing land in zea maize cultivation in this area and with 3 replication in complete randomized block design were studied. Treatments consisted of: 1 time moldboard method + 2 time longitudinal Disk+ leveler (convention tillage), 1 time tillage by using of compound tillage machine (chisel pillar)+ 2 time longitudinal disk (medium tillage)+ tillage method with 2 time longitudinal Disk+1 time cross plough (reduced tillage). Research results showed that convention tillage treatment with 71230 bush per hectare have lowest bush density amount, reduced tillage treatment by disk with 79000 bush per hectare had highest bush density amount but rather than tillage method with Chisel plough that its bush amount was 77330 hadnʹt significant difference . Highest amount of zea maize seed yield with 8.8 Ton per hectare obtained from reduced tillage treatment with disk, tillage treatment by using of Chisel plough and convention tillage treatment had 8.5 and 8.3 ton seed yield mount per hectare, respectively. Convention method with 31.4 percent moisture had highest seed moisture amount, tillage treatment with Chisel and Disk were 29.5 and 27.6 percent humidity. Whatever the amount of zea maize seed moisture was lower, price of the product became more.
