An investigation on effect of organic nutrients on physiological and flowering characters of bittergourd (Momordica charantia L.) ecotype “Mithipagal” through organic nutrient management practices was carried out at the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar during 2016-17.The experiment comprised of 13 treatments replicated thrice was executed following the principles of Randomized Block Design. Results of the experiment revealed that the application of vermicompost @ 5t ha-1 and sea weed extract 3% along with Azospirillum @ 2 kg ha-1 improved the growth, yield and quality performance of bitter gourd ecotype “Mithipagal”. Among the treatments, T5 (vermicompost 5t + sea weed extract 3% + azospirillum 2kg ha-1) selected the highest in physiological characters viz., leaf area index ,chlorophyll content, photosynthetic rate and dry matter production. It was closely followed by T2(vermicompost 5t + humic acid 2% + Azospirillum 2 kg ha-1). Regarding with flowering characters viz., days taken to first female flowering and number of female flowers, the best values are found with application of T5 .which was followed by T2 and the least values are found in control.
