An experiment titled ‘Study on the effect of different levels of NPK alone and in combination with liquid biofertilizers on the quality parameters and nutrient uptake status in Marigold (Tagetus erecta L. Cv. Pusa Naringa Gainda)” was conducted in two Rabi seasons of year 2015-16 and 2016-17 at Floriculture Research Station, Sri Konda Laxman Telangana State Horticulutural University, Rajendranagar, Hyderabad. Among the treatments in the pooled data, T7 (100% N + 100% P + 50% K + liquid KSB) recorded significantly maximum flower diameter (5.4cm), flower weight (6.4g), Shelf life (4.0 days), maximum uptake of Nitrogen content (3.3%), whereas maximum Phosphorous content (0.34%) was recorded with T2 (75% N + 100% P + 100% K + liquid azotobacter) and maximum Potassium content was recorded (1.47%) with T13 (50% N + 50% P + 50% K + liquid azotobacter + PSB + KSB) in leaves of Marigold.
