The present research work was carried out at to study the growth and yield of barley as affected by irrigation, sowing method and phosphorus level. The experiment had three factors i.e irrigation frequency viz. no irrigation (Io), one irrigation (I1) at 25 DAS, two irrigations (I2) one at 25 DAS and 45 DAS and sowing method viz. line sowing (L) and broadcasting (B) method and four levels of phosphorus viz. 0 Kg ha-1, 17 Kg ha-1, 25 Kg ha-1 and 33 Kg ha-1. The experiment was laid out in a Spilt-spilt plot design with three replications. The experiment field was fertilized with cowdung, Urea, Triple Super Phosphate (TSP), Muriate of Potash (MP) and Gypsum. From the results of the present study the following conclusions can be drown: i. Irrigation applied two times at tillering and booting stages, showed better performance on growth and grain yield. ii. A line sowing method was appropriate for growth. iii. Phosphorus applied with P3 treatment i.e 33 kg phosphorus ha-1 at produced higher grain yield and also better for growth. So, a line sowing method with 33 kg phosphorus ha-1 and two times irrigation at tillering and booting stages is better for growth and yield of barley.
