ABSTRACT

Exploring the relationship among inorganic potassium fractions, yield and soil properties were important to know the best extractant for available K for cauliflower in the light textured soils of Rangareddy district. Surface soils in bulk were collected from thirty locations of Rangareddy district and pot culture experiment was carried out. Inorganic K fractions were analysed to evaluate the relative efficiency of extractants in determining the available K. Here, we have investigated the relationships among the soil properties, between soil properties and K uptake, between soil properties and yield, between K fractions and K uptake, between K fractions and yield. Organic carbon (r = 0.65**), available nitrogen (r = 0.60**)  exhibited a significant positive correlation with NH4OAc (1N) extractable K. Available potassium extracted by NH4OAc showed a significant positive correlation with NaBPh4 (0.2 M) extractable K (r = 0.93**), 1M HNO3 (r = 0.55**) and also with citric acid extractable K (r = 0.67**). Among all the extractants 1N NH4OAc extractable K showed higher positive correlation with curd yield (r = 0.975**).  It had a significant positive correlation with NaBPh4 (0.2 M) extractable K (r = 0.926**).
