The field experiment was conducted to evaluate the different sources of organic manures in comparison with recommended dose fertilizer (RDF) on greengram at South farm, Karunya Institute of Technology and Science, Coimbatore, India. The field experiment was laid out in Randomized Block Design and replicated thrice during kharif and rabi seasons of 2022. The field study comprised of nine treatments, two organic treatments with sole organic manures at 100% on N equivalent basis (vermicompost, farmyard manure) another three treatments consisted of 25%, 50% and 75% combination of each manure. These two organic manures (vermicompost, farmyard manure) were combined with 50% RDF through inorganic fertilizers (12.5:25:12.5 of N, P2O5 and K2O kg ha-1) as a combination of organic and inorganic treatments and one sole 100% inorganic treatment through inorganic fertilizer (25:50:25 of N, P2O5 and K2O kg ha-1). A control treatment was maintained in the layout to compare the performance of all the treatments. The results showed that among the different combinations of organic and inorganic treatments, 100% recommended dose of fertilizer through inorganic (25:50:25 of N, P2O5 and K2O kg ha-1) (T7) fertilizer significantly enhanced the growth and yield of greengram which was closely followed by vermicompost 100% on N equivalent basis.
