The present investigation entitled “Response of organic farming on quality evaluation of rice (Oryza sativa
L.)” was carried out during kharif season on randomized block design with four replications in sarjoo- 52 variety. Five treatments of organic farming were taken namely T1 ( In situ decomposition of rice straw and pressmud @ 5.0 t/ha with PSM and Azotobacter
), T2 ( In situ decomposition of rice straw and FYM @ 5.0 t/ha with PSM and Azospirillium
), T3 ( In situ decomposition of rice straw with pressmud @ 10.0 t/ha and PSM), T4 (In situ decomposition of rice straw with FYM @ 10.0 t/ha and PSM), T5 ( In situ decomposition of rice straw with poultry manure @ 5.0 t/ha and PSM).
Maximum and minimum test weight of rice variety was noticed in treatment T5 (29.00g) and treatment T3 (25.00g). Highest L: B ratio was recorded in treatment T5 (3.00) while minimum L: B ratio was noticed in treatment T3. Maximum starch iodine blue value was recorded in treatment T5 (70.73%) while minimum starch iodine blue value was recorded in treatment T4 (70.60%). The protein content was observed maximum in T5 (8.85%) and minimum protein content was noticed in T3 treatment (7.73%). The amylose content was noticed highest in T5 treatment (22.90%) and minimum content was reported in T3 treatment (20.47%). The total mineral content of rice grain was observed maximum in T5 treatment (1.40%) while minimum content was recorded in T3 treatment. The protein profiling of rice grain quality indicates the prominent bands showed in the T5, T4 and T3 treatment while light band showed in T1 and T2 treatments.
