Abstract: Field experiments were conducted during samba seasons of 2017-2018 and 2018-2019 to study the effect of organic manures and inorganic nutrients on yield, physicochemical and cooking quality of Seeragasamba rice. The experiments were conducted in sandy clay loam with pH around 7.5. Fourteen treatments comprising different sources of organic manures and inorganic nutrients were replicated thrice under RBD. The treatments are as follows: T1- 100%N through Green Manure, T2-75%N through Green Manure+25%N through RDF, T3-50%N through Green Manure+50% N through RDF, T4 -100%N through FYM, T5-75% N through FYM+25% N through RDF, T6-50% N through FYM+50% N through RDF, T7-100% N through Composted Poultry Manure, T8-75%N through Composted Poultry Manure+25%N through RDF, T9-50% N through Composted Poultry Manure+50%N through RDF, T10-100%N through Vermicomposted Pressmud, T11- 75% N through Vermicomposted Pressmud+25% N through RDF, T12-50% N through Vermicomposted Pressmud + 50% N, T13-RDF @ 56:37:37 NPK Kg/ha through in organic and T14 - Control (No Nitrogen). The results revealed that in both samba seasons, the highest grain yield was obtained in (T3) application of 50% N through green manure + 50% N through RDF and it was followed by the (T12) application of 50% N through vermicomposted pressmud + 50% N through RDF. However, both treatments were found to be on par with each other. The milling recovery, head rice recovery, protein and starch amylose content were also found to be higher in these treatments as compared to others. The cooking quality evaluated interms of increased length and breadth of cooked rice were also enhanced in these treatments. The sensory evaluation attributes viz., colour, taste, texture and overall acceptability were also increased in T3 and T12.
