Abstract: A field trial was conducted during summerseason of 2014-15 at Agronomy Instructional Farm, Department of Agronomy, C.P. College of Agriculture, S.D. Agricultural University, Sardarkrushinagar, Gujarat (India), to assess the effect of nitrogen and potassium on yield, nutrient content and uptake by forage sorghum [Sorghum bicolor (L.) Moench] on loamy sand. The experiment encompassed three levels of nitrogen viz., 60, 80 and 100 kg N ha-1 and three levels of potassium viz., 0, 25 and 50 kg K2O ha-1. The experiment was laid out in randomized block design (Factorial) with four replications. Results revealed that individual application of nitrogen @ 100 kg ha-1 and potassium @ 50 kg ha-1 produced the significantly maximum plant height (173.98 cm), leaf area per plant (224.63), stem diameter (1.85 cm), number of leaves per plant (8.19), green leaf weight per plant (52.82 g), dry leaf weight per plant (21.95 g), green stem weight per plant (132.90 g), dry stem weight per plant (62.78 g), green (244.81 q ha-1) and dry fodder (122.14 q ha-1) yields were recorded due to application of 100 kg N ha-1.Application of potassium @ 50 kg ha significantly influenced the number of leaves per plant, green leaf weight (g/plant), dry leaf weight (g/plant), green stem weight (g/plant), green fodder yield (q ha-1) and dry fodder yield (q ha-1). Effect of different levels of nitrogen and potassium application on forage sorghum influence by the nitrogen content and nitrogen, phosphorus and potassium uptake. Application of nitrogen significantly influenced the quality parameters like crude protein content, crude fiber content and chlorophyll content in forage sorghum.
