Abstract:
A field experiment was conducted in the year 2018 during the Kharif season at the Instructional Farm, Odisha University of Agriculture and Technology (OUAT), Bhubaneswar, Odisha to study the effect of application of fly ash (FA) in conjunction with other chemical fertilizers (CF) and farm yard manure (FYM) on the protein content and protein fractions of rice (Oryza sativa) cv. ‘Swarna’. The treatments were applied in 5m × 3m size plots taking nine treatments replicated thrice in a randomized block design (RBD). The soil was acidic and the experimental FA was alkaline in nature. It was observed that the crude protein content of rice grains varied from 7.91% to 9.19% and that of true protein from 6.81% to 7.95%. The true protein content decreased by the application of only FA but increased significantly with the inclusion of NPK along with FYM. The amount of protein fraction albumin varied from 0.47% to 0.57% and that of globulin from 0.42% to 0.51%. The minor fraction prolamin varied from 0.09% to 0.15% and the major fraction glutelin from 4.94% to 5.71%. It is proved that cumulative application of only NPK fertilizers had no effect on the crude protein but in combination with FA and FYM reduced the amount of crude protein content and NPN along with the true protein content.
