Effects of plant density and nitrogen levels on yield and yield components in corn
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 15
Abstract
In the present research the effects of different levels of nitrogen fertilizer and plant density on yield and yield components in corn in field conditions was under investigation.A factorial experiment was conducted in Moghan area as a complete randomized block design with 3 replicates in year 2010. The first factor was four levels of nitrogen fertilizer (225 and 150, 75, 0) and the second factor was plant density (12, 10, and 8) p/ m2 within 60 cm row spaces. In this study number of grains per row, number of grains per corn, 1000 grain weight and grain yield were evaluated. Results from variance analysis indicated that there were significant differences between interactional effects of nitrogen fertilizer and plant density for all traits. In fertilizing treatment of 225 kilogram nitrogen per hectare and plant density of 10 plants per square meter more yield was obtained and in fertilizing treatment of 225 kilogram nitrogen in hectare and also minimum yield in fertilizing treatment of 75 kilogram per hectare and plant density of 12 plants per square meter was observed.
