The experiment was conducted to study the effect of levels of potassium on yield, nutrient uptake, fertility status and economics of cotton grown in Vertisol at Akola during kharif season of 2009-10 to 2011-12. There were seven treatments comprising of potassium application through soil and foliar along with RDF (50 kg N + 25 kg P2O5 ha-1) laid out in Randomized Block Design with three replications. The pooled results of the present experiment revealed that, application of 37.5 kg K2O ha-1 along with recommended dose of fertilizers (50:25:0 NPK kg ha-1) recorded significantly highest seed cotton yield (14.64 q ha-1) followed by recommended dose of fertilizer + 25 kg K2O ha-1 (14.15 q ha-1). Lowest seed cotton yield (9.91 q ha-1) was recorded in control treatment. The soil fertility status and uptake of major nutrient was significantly influenced with the application of RDF + 37.5 kg K2O ha-1. The higher B: C ratio, GMR and NMR was observed with the application of RDF + 37.5 kg K2O ha-1. Apparent recovery percentage and fiber quality parameters i.e. span length, uniformity ratio, fineness micronaire and bundle strength tenacity were improved with the application of RDF + 37.5 kg K2O ha-1.
