The present field experiment was conducted at Horticultural Research and Extension Centre, Kanabargi (Belagavi Dist.) (Under University of Horticultural Sciences, Bagalkot) during Rabi season of 2019-20 and 2020-21. The objective of the experiment was to study the application of liquid jeevamrutha at different dosage and frequency on plant nutrient status (N, P & K) of marigold cv. Calcutta Orange. The experiment was designed in two factorial randomized block design with each factor having three levels. Three different levels of liquid jeevamrutha viz., @ 500 l/ha, @ 750 l/ha and @ 1000 l/ha at different frequencies are 15 days, 21 days and 30 days was applied to marigold by drenching around the plant root system. The combination effect of different dosage and frequency of liquid jeevamrutha application was compared with recommended package of practice (RPP). The results revealed that application of higher dosage of liquid jeevamrutha @ 1000 l/ha at an interval of 15 days recorded significantly higher plant nutrient status. Similarly in interaction treatments pooled data, revealed that D₃F₁ (liquid jeevamrutha @ 1000 l/ha at 15 days interval) recorded significantly highest nitrogen (59.96 kg/ha), phosphorous (14.13 kg/ha) and potassium (43.75 kg/ha) during after harvest was compared to other treatments.
