Improving nitrogen fertilizer absorption and its effect on quality and seed yield of corn (Zea mays L.)

Abstract

Improving nitrogen uptake by pyraclostrobin application in maize under green house and field conditions were investigated. There were three series experiments conducted in dry season, 2011 and 2012. The research was conducted using nested design and three replications. Nested design was applied in order to get information as careful as possible about the role of treatment, especially the main factor. The first experiment was carried out in the field while the second and third were in the green house.The experiments had two factors, pyraclostrobin application and nitrogen fertilizer. Vegetative growth, flowering and earing age, chlorophyll content, yield, amylose and protein content were evaluated. Application of pyraclostrobin, significantly increased nitrogen fertilizer efficiency. Amylose content and fresh yield were different on nitrogen and pyraclostrobin application. Application of pyraclostrobin 400 ml/ha significantly increased amylose 10.85-18.5%.Both amylose and protein content were increased by nitrogen fertilizer application. Vegetative growth and chlorophyll content were affected by nitrogen and pyraclostrobin significantly.
