A field experiment was conducted during rabi 2002-03 on deep vertisol at Research and Development Farm Ugar Khurd, Athani taluk Belgaum district of Karnataka State, to study the effect of micronutrients (zinc and iron) and time of N application on growth and yield of durum wheat. Data on grain and straw yields differed significantly both due to micronutrients and time of nitrogen application. Among micronutrients application, combined application of zinc and iron each @ 25 kg per ha recorded significantly higher grain yield (42.23 q/ha) as compared to control. Among the different time of nitrogen application tested, nitrogen applied in three splits i.e., ½ basal + ½ 30 DAS + ¼ 60 DAS and «basal + 1/3 30 DAS + 1/3 60 DAS recorded significantly higher grain yield (41.44 and 40.96 q/ha respectively) as compared to nitrogen applied in two splits i.e., ½ basal + ½ 30 DAS (38.91 q/ha). However, the interaction effects were found to be non-significant.  The correlation studies between yield and growth as well as yield components revealed that grain yield had positive and significant correlation with total dry matter production, number of tillers at 30, 60 and 90 DAS, leaf area at 60 and 90 DAS, effective tillers, 1000-grain weight, number of grains per ear head and weight of grains per earhead.
