The present study was carried out at the research farm of Krishi Vigyan Kendra, Sirsa during kharif 2014. The climate of this tract was semi-arid, sub-tropical with hot and dry summer and cold winters. The maximum temperature during summer months of May and June reached up to 47.2 °C. The total rainfall obtained during the crop season was about 327.5 mm. The cropping history of field from 2011 was cluster bean in kharif and in rabi crop wheat was grown. Seed cotton yield increased significantly with the application of K and mean highest yield (2751.98 kg/ha) was observed where K was applied @ 60 kg/ha along with two foliar spray of 1% of KNO3. The seed cotton yield increased significantly in the high K fertility soil up to the treatment T4 (N175P60 + K30). However, the mean seed cotton yield was higher in high K fertility soil as compared to medium K fertility soil. It indicates that in the high K fertility soils, application of potassium at the rate of 30 kg/ha is sufficient of optimizing the seed cotton yield. The number of bolls per plant and boll weight increased with application of K in all the treatments in both soils where as the GOT and harvest index remained unaffected.
