Abstract

The critical limits of available K in soil with two different extractants were determined through a pot culture experiment with 30 soils of Rangareddy district. NH4 OAc NN) and NaB Ph4 (0.2 M) extractable K were found to be positively and significantly correlated with plant K content and curd yield of cauliflower. The critical limits of available K for cauliflower growing soils of Rangareddy district were found to be 120.8 and 334.2 ppm, respectively, for NH4 OAc (NN) and NaB Ph4 (0.2 M). The critical plant of K content of cauliflower was found to be 2.6%. The curd yield of the cauliflower increased with increased levels of potassium.
