The present experiment was carried out at research field of Seed Science and Technology in the Department of Genetics and Plant Breeding, Sam Higginbottom Institute of Agriculture, Technology and Science, Naini Agriculture Institute, Prayagraj (U.P.) during Rabi season 2020-2021, in order to standardize the suitable treatment of mustard (Pusa Mustard-21). Two organic manures viz. Farmyard manure and Vermicompost are studied with different doses of NPK, are replicated thrice with thirteen treatment combinations in a Randomized Block Design (RBD). Different fertilizer treatments with control (Unhardened) were evaluated by screening of various doses viz., T0 – Control, T1 – FYM 10 t/ha + 25% N:P:K, T2 – FYM 10 t/ha + 50% N:P:K, T3 - FYM 10 t/ha + 100% N:P:K, T4 – Vermicompost 5 t/ha + 25% N:P:K, T5 – Vermicompost 5 t/ha + 50% N:P:K, T6 – Vermicompost 5 t/ha + 100% N:P:K, T7 – FYM + Vermicompost + 25% N:P:K, T8 – FYM + Vermicompost + 50% N:P:K, T9 – FYM + Vermicompost + 1

Integrated Nutrient Management is the process to maintain the soil fertility and plant nutrient supply at an optimum level through optimization by the benefits of all possible sources of nutrients like inorganic, organic and bio-fertilizers. The only chemical fertilizer application is influential elements for yield and quality of mustard seed. So, the amelioration of soil condition and increase yield potentiality by applying combination of organic and inorganic fertilizers rather than only inorganic (chemical) fertilizers.It is concluded from the present study that the seeds of mustard variety Pusa Mustard 21 treating with FYM + Vermicompost + 100% N:P:K enhanced the Field emergence percentage, Plant height (cm), Numbers of branhes per plant, Numbers of siliqua per plant, Number of seeds per siliqua, Seed yield per plant (gm), Seed yield per plot (gm), Biological Yield per plot (gm) and Harvest index followed by Vermicompost 5 t/ha + 100% N:P:K and FYM + Vermicompost + 50% N:P:K as com
