A field experiment was conducted at Main Agricultural Research Station, UAS, Dharwad during kharif, 2017 to study the effect of nutrient levels and growth regulators on yield, plant nutrient content, plant nutrient uptake and soil nutrient content of transplanted pigeonpea under rainfed conditions. The experiment comprising of 3 nutrient levels as main plots and 4 sub plot treatments of foliar application of micronutrients and growth regulators compared with 1 single control were laid out in split plot design with 3 replications. The results showed that among nutrient levels, application of 50:100 N:P2O5 kg ha-1 (N3) recorded significantly higher organic carbon, nitrogen, phosphorus and potassium content in soil after harvest and significantly higher nitrogen, phosphorus and potassium uptake by crop at harvest. Significantly higher zinc uptake was recorded with application of 25:50 N:P2O5 kg ha-1 (N1). Significantly higher grain yield was recorded with 37.5:75 N:P2O5 kg ha-1 (N2) as compared to N1 which was at par with N3. Among the interactions, significantly higher nitrogen uptake and grain yield was recorded with application of N2 along with foliar spray of salicylic acid (0.02%) + ZnSO4 (0.5%) + soluble boron (0.2%) (F2). Significantly higher phosphorus and potassium uptake was recorded with treatment N3F2.
