Abstract: An experiment was conducted to evaluate the effect of fertigation and consortium of biological sources on growth parameters, yield attributes and flower yield of tuberose during 2015-2016. The treatment consists of three level of recommended dose of fertilizer through fertigation (RDFTF) gradients (125, 100 and 75 % of NPK), recommended dose of microbial consortium (5 kg @ acre-1), foliar spray of panchakavya (3 % and 4 %) and humic acid (0.4 % and 0.5 %) were laid out in randomized block design with two replications. The results revealed that the morphological characters namely plant height and number of leaves plant-1 at various growth stages were recorded highest in 100 % RDFTF + microbial consortium @ 5 kg acre-1 + 3 % panchakavya and 0.4 % humic acid. The yield attributes viz., number of florets spike-1, spike length, number of spikes clump-1, were registered highest with treatment received 100 % RDFTF + microbial consortium @ 5 kg acre-1 +3 % of panchakavya and 0.4 % of humic acid when compared to 100 % recommended dose of fertilizer through soil application. The yield attributes namely single flower weight was noticed highest of 1.81g respectively with 100 % NPK+ microbial consortium @ 5 kg acre-1 +3 % panchakavya and 0.4 % humic acid when compared to fertigation alone. The percent increase of flower yield by 100 % NPK+ microbial consortium @ 5 kg acre-1 +3 % panchakavya and 0.4 % humic acid was 39 % over soil application of recommended fertilizers. Overall findings concluded that treatment combinations of 100 % NPK+ microbial consortium @ 5 kg acre-1 +3 % panchakavya and 0.4% humic acid were recorded higher flower yield and yield attributes besides quality parameters.
