A field experiment was conducted during late kharif 2018-2019 at College of Horticulture, Anantharajupeta to evaluate the effect of different organic manures and bio- fertilizers on plant nutrient uptake and post-harvest soil fertility status in senna cv. ‘Sona’. Analysis of plant nutrient uptake by senna has revealed that significantly maximum uptake of nitrogen content (174.87 kg ha-1) in the plant sample was observed by application of 100% RDN through urea, whereas, significantly maximum plant nutrient uptake of phosphorous (48.22 kg ha-1) and potassium (173.84 kg ha-1) contents were observed by application of 100% RDN through vermicompost in combination with bio-fertilizers viz., Azospirillum and PSB. However, post-harvest soil fertility analysis of senna has revealed that significantly maximum nitrogen content (168.65 kg ha-1) and potassium content (440.51 kg ha-1) in the soil was recorded by application of 100% RDN through neem cake, whereas, significantly maximum content of phosphorous fertility in the soil (101.82 kg ha-1) was noticed with the application of 100% RDN through vermicompost in combination with bio-fertilizers viz., Azospirillum and PSB.
