Abstract

One of the most important methods in integrated WEED management to reduce the amount of herbicides is nutrient management. In order to study NITROGEN split application pattern and Nicosulfuron dosages, an experiment was conducted as split plot based on randomized complete block design with 3 replication in the research field of natural resources Sabzevar in 2011-2012. Experimental factors were NITROGEN SPLITTING PATTERNs (75% as sowing +25% as top dressing, 50% as sowing +%50 as top dressing and 25% as sowing +75% as top dressing) as main factor and herbicide amounts (Control, Recommended, Recommended + 25% and Recommended - 25%) as sub plot. Amount of applied NITROGEN was 225 kg as urea and herbicide dose was 1.5 lit. ha-1 (80 g ai ha-1). The results showed that biological yield, economic yield, number of rows in cob and seed per rows affected by NITROGEN split application and 25% at sowing+75% as top dressing was the best treatment compared to others. Although, increasing 25% herbicide dose increased yield and yield component of CORN but hadn’t significant difference with recommended dose. Generally, the results showed that the NITROGEN application as 25% at sowing and 75% at top dressed and recommended dose of herbicide is the most appropriate attendance to obtain maximum yield.
