Influence of Nitrogen Timing and Levels on Yield and Yield Components of Canola

Abstract

The experiment on response of nitrogen application timing and levels on yield and yield components of canola was conducted at New Developmental Farm the University Agriculture Peshawar, during Rabi season 2013-2014. The experiment consist of three timing (full at sowing, split application and rosette stage) and levels 80 and 120kg N ha^-¹ of nitrogen. The experiment was designed in randomized complete block with three replications. Canola Cultivar  Abasin-95 was used as testing crop. The results indicated that more number of branches plant^-¹ (7), number of pods plant^-¹ (276), grain pod^-¹ (21), biological yield (3659kgha^-1), grain yield (1337kg ha^-1), thousand grain weight (4g) and harvest index (12%) were significantly affected except number of branches plant^-1. Split application were proved more effective as compared  full at sowing or rosette stage of both nitrogen levels 80 and 120kg N ha^-1 to obtain higher yield in agro- ecological conditions of Peshawar.
