The Effects of Tillage System and Varieties on Yield and Yield Components of Corn (Zea mays L.)
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 1
Abstract
In order to investigate the effect of tillage system on silage yield and yield components in four varieties of corn, an experimental was done in a split block design, treatments arrangement with four replication in north of Iran in 2012. Tillage system was the main plot in three levels: 1. Conventional tillage (CT). 2. Minimum tillage (MT) 3. No-tillage (NT). Other factor were four varieties of corn (SC 500, SC 260, AS62 and SC704). Plant height,ear diametr,dry and wet ear weight,dry and wet stem weight, dry and wet leaf weight , dry and wet silage yield. The results indicated that tillage systems had not significant difference on dry and wet silage yield. Because of the more expensive ,more soil practice , more irrigation and more time for land preparation at minimum and conventional tillage systems in compare of no- tillage system, i propose no-tillage system. Effect of varieties on silage yield was significantly different. Maximum silage and dry silage yield 32/76t/ha and 12/13 were obtained by SC704.
