Abstract: abiAn investigation was conducted in rabi season of 2013-14 to find out the suitable dose of Nitrogen in barley crop and to study the time and dose of nitrogen application for higher productivity of barley. The experiment was laid out in split plot design with four levels of nitrogen (0, 20, 40, and 60 kg N ha-1) and three time of application (½ at the time of sowing and ½ after first irrigation, 1/3 at sowing and 2/3 after first irrigation, 1/3 at sowing and 1/3 after first irrigation and 1/3 after second irrigation) with three replications. Nitrogen level (60 kgha-1) treatment and Time of application (1/3 at sowing and 2/3 after first irrigation) treatment was found best over rest of the treatments in all aspects of growth parameters i.e., IPP, Plant height, Number of shoots, Dry matter accumulation and Leaf area index (LAI). Treatment N3 (60 kg N ha-1) increases significantly and was found maximum with No. of shoots (393.45), Plant height (70.70 cm), Leaf area index (5.10) & Dry matter accumulation (621.25 g) under main plot treatments. Treatment T2 (1/3 at sowing and 2/3 after first irrigation) was found best with No. of shoots (389.96), Plant height (61.31 cm), Leaf area index (4.46) and Dry matter accumulation (554.94 g) as compared to other treatments and being at par with Treatment T3 (1/3 at sowing and 1/3 after first irrigation and 1/3 after second irrigation) in all aspects of growth parameters.
