- Abstract
A study was conducted in the Department of Agronomy, University of Agriculture, Faisalabad, Pakistan to check the effect of different potassium (K) levels on water relations, fibre quality and yield traits of two cotton cultivars (FH-942 and FH-113). Four levels of foliar potassium (0, 1, 1.5 and 2%) were arranged in RCBD replicated thrice with a net plot size of 1.5 m x 5.0 m in farm area. The results revealed significant differences for fibre quality and yield parameters due to foliar applied K levels. However, foliar applied K @ 1.5% performed better than all other treatments. Maximum water (-1.08 and -1.11MPa), osmotic (-1.43 and -1.45 MPa) and turgor potential (0.64 and 0.56 MPa) were noted in K level of 1.5% both at 40 and 60 DAS. The same K level showed maximum fibre strength (28.12g /tex), fibre length (32.24 mm), fineness (6.22 micronaire), uniformity (54.60%) and fibre elongation (5.80%). The yield related parameters i.e. number of sympodial and monopodial branches, bolls number, ginning outturn and yield of seed plus cotton were significant and more at 1.5% foliar applied potassium level. These parameters were better in cultivar FH-942 than FH-113.
