Investigation has been carried out to study the effect of fertigation evels i.e., 100%, 75% and 50% of recommended doses of Fertilizers (RDF) and foliar spray of bio stimulants, three levels of humic acid (0.1%, 0.2% and 0.3%) and panchagavya at 3% in yield parameters viz., flower yield/m2, flower diameter (cm), flower discdiameter (cm), flower stalk length (cm), and flower stalk girth (cm), of gerbera (Gerbera jamesonii Bolus ex Hooker F.) var. Debora under polyhouse conditions. The treatment T4 (100% RDF+3% panchagavya + 0.3% humic acid) recorded the highest flower yield, largest flower diameter and disc diameter and longest stalk. However, the flower stalk girth was highest with T8 (75% RDF + 3% panchagavya + 0.3% humic acid).
