Abstract:A field study was undertaken at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during
Kharif season of year 2018, to evaluate the effects of integrated nutrient management on protein content, their yield and economics of transplanted rice (
Oryza sativa L.). This experiment was laid out in randomized block design (RBD) with eight treatments
viz.- T
1- Control, T
2- RDF 100% (150:60:60:20 NPK and zinc sulphate), T
3- RDF 75% + 25% N through poultry manure, T
4- RDF 75% + 25% N through FYM, T
5- RDF 75% + 25% N through pressmud, T
6- RDF 50% + 50% N through poultry manure, T
7- RDF 50% + 50% N through FYM, T
8- RDF 50% + 50% N through pressmud, respectively and replicated three times in the field. The study of the data of the experiment showed that the protein content was non-significant, however, yield of protein of transplanted rice were significantly influenced through different INM practices during the experiment and economics were also differed with integration of chemical fertilizers and organic manures.
Further results indicated that the protein content in grains of transplanted rice was found maximum under treatment T2 [RDF 100% (150:60:60:20 NPK and zinc sulphate)], while, this data was non-significant. However, significantly maximum protein yield (314.99 kg ha-1) was recorded under treatment T2 [RDF 100% (150:60:60:20 NPK and zinc sulphate)], which remained at par with treatment T3 (RDF 75% + 25% N through poultry manure) (298.07 kg ha-1). Maximum gross return (Rs. 84199 ha-1), net return (Rs. 43644 ha-1) and B: C ratio (Rs. 1.08 ha-1) were also obtained under T2 treatment [RDF 100% (150:60:60:20 NPK and zinc sulphate)].
