ABSTRACT
A study was conducted in three successive seasons during 2004-06 on loam soil at three different sites in tehsil Faisalabad. The objective was to investigate the response of cotton (cv. NIAB-111) to different levels and times of K-application. The treatments comprised three potassium doses (0, 62.5 and 125 kg/ha) and its application on three times (full at sowing, full at first irrigation and ½ at sowing + ½ at first irrigation). The results indicated that potassium doses and application times significantly affected seed cotton yield. On an average, the highest seed cotton yield (2418.55 kg/ha) was obtained when crop was fertilized @ 125 kg K (full at sowing) closely followed by 62.5 kg (full at sowing) (2409.77 kg/ha). However, both these doses were statistically at par. The lowest yield was noted in control (2192.98 kg/ha) where no potassium fertilizer was applied. Hence application of K at economical dose of 62.5 kg per hectare is recommended in tehsil Faisalabad.
