The experiment was laid out on the basis of randomized complete block design under factorial arrangement with three replications. Factors were: foliar application of potassium (control, vegetative phase, reproductive phase and vegetative+ reproductive) and plant density (10, 20 and 30 plant.m-2 respectively). The results showed that foliar application of solo-potash on vegetative + reproductive had the maximum plant height (28.75cm), branch number (8.33 branch per plant), pod per plant (20.71), biological yield (994.44 kg.ha-1) and economic yield (488.49 kg.ha-1). Increasing plant density plant height augmented (5.12%), lateral branch number (16.55%), pod per plant (32.06%) compared to 10 plant. overall, foliar application of solo-potash on vegetative + reproductive stage and 20 plant.m-2 produced the highest economic yield (480 kg.ha-1) on rain-fed condition. %> http://arpe.gonbad.ac.ir/article-1-182-en.pdf %P 91-104 %& 91 %! %9 Research %L A-10-145-3 %+ %G eng %@ 9 %[ 2015
