A pot experiment was conducted at Experimental area, Agronomy Department PMAS- University of Arid Agriculture Rawalpindi to see the effect of different levels of nitrogen fertilizer on the growth and physiological traits of Sorghum Sudan Grass during March, 2022. Completely randomized designed was applied along with three replications. Seeds of Sorghum Sudan grass were collected from NARC Islamabad. Nitrogen fertilizer was applied in pots on 30th March, 2022, according to the treatments. Nitrogen played a significant role in the growth and physiology of Sorghum Sudan Grass. Nitrogen @ 150 kgha-1 is the best among other four treatments and attained the highest plant heights in three times (21.355, 65. 153 and 100.620 cm) respectively. However, results of nitrogen @ 200kgha-1 are approximately statistically at par with NPK. Nitrogen @ 150 kgha-1 gained the highest position in two times data (0.7050 and 1.4250) respectively. Nitrogen @ 200 kgha-1 gained less value than nitrogen @150kgha-1 might be excessive dose. Nitrogen nutrition played a key role in the enhancement of leaf area values; however nitrogen @150kgha-1nutrition had the top position (1.140 and 1.950) during two times respectively. Leaf area index data had statistically significant results but among the nutrition treatments nitrogen @150kgha-1nutrition is the best option attaining the highest values (91.475 and 152.550) respectively in two times. Nitrogen fertilizer at different levels had statistically significant effect on crop growth rate of sorghum plants; however nitrogen @150kgha-1nutrition treatment attained the highest value (0.5333) which was statically at par @200kgha-1nutrition treatment. Nitrogen @150kgha-1nutrition treatment had the top position (4061.9) but other three doses of nitrogen values having minute difference with nitrogen @150kgha-1 and higher than control. Four doses of nitrogen fertilizer produced more net assimilation rates than control and nitrogen @150kgha-1gained the highest value (45.653) which was statistically at par with nitrogen @200kgha-1(43.521).Nitrogen fertilizer is an inorganic fertilizer provides the nutrition the plant fastly and provides better performance at nitrogen @150kgha-1. Nitrogen @200kgha-1 showed better performance than control but less than nitrogen @150kgha-1, therefore this finding improves the economics of the study.
