Abstract
The current study was steered at Bhagwant University Ajmer, Rajasthan during the Rabi season of years 2019-20 and 2020-21 to find out the combined application of different organic and inorganic sources of nutrients on flowering behaviour and yield attributing traits of Marigold (Tagetes erecta L.) under Agro-climatic conditions of Ajmer Zone. Total ten treatments were used in Randomized Block Design (RBD) and replicated three times. The treatments namely T1- Control, T2- 100% RDF (N:P: K @ 120:80:60 kg/ha), T3-100% RDF + 25% VC, T4- 100% RDF + 25% FYM, T5- 75% RDF + FYM + Biofertilizers, T6- 75% RDF + VC + Biofertilizers, T7- 75% RDF + FYM + VC + Biofertilizers, T8- 50% RDF + FYM + VC + Biofertilizers, T9- 50% RDF + FYM + Biofertilizers and T10- 50% RDF + VC + Biofertilizers. Total 30 treatment combinations were formulated in present experiment. During the experimentation, observations were recorded on various flowering and yield attributing parameters like days taken to first bud initiation, days taken for opening of flower bud, days taken to first flowering, days taken to 50% flowering, flower stalk length, diameter of flower, number of flowers per plant, fresh weight of flower, flower yield per plant, flower yield per plot, flower yield (q/ha) and B:C ratio of applied treatments. However, the maximum flowering and yield were found in T7- 75% RDF + FYM + VC + Biofertilizers as compared to T8- 50% RDF + FYM + VC + Biofertilizers.
