A field experiment was conducted at the experimental field of Pandit Deen Dayal Upadhyay Institute of Agricultural Sciences, Utlou, Bishnupur District, Manipur during Rabi season of the year 2023-24 to monitor the response of phosphorus and potash on the growth and yield of field pea (Pisum sativum L.). The experiment was laid out in Factorial Randomized Block Design (FRBD) of 9(nine) treatments, containing three levels of phosphorus and three levels of potash i.e. T₁(P₁K₁): 0 kg P₂O₅/ha + 0 kg K₂O/ha, T₂(P₁K₂): 0 kg P₂O₅/ha + 30 kg K₂O/ha, T₃(P₁K₃): 0 kg P₂O₅/ha + 60 kg K₂O/ha, T₄(P₂K₁): 40 kg P₂O₅/ha + 0 kg K₂O/ha, T₅(P₂K₂): 40 kg P₂O₅/ha + 30 kg K₂O/ha, T₆(P₂K₃): 40 kg P₂O₅/ha + 60 kg K₂O/ha, T₇(P₃K₁): 80 kg P₂O₅/ha + 0 kg K₂O/ha, T₈(P₃K₂): 80 kg P₂O₅/ha + 30 kg K₂O/ha and T₉(P₃K₃): 80 kg P₂O₅/ha + 60 kg K₂O/ha with three replications. From the present investigation it is found that all the growth attributes and yield attributes were significantly influenced by the application of phosphorus and potash. Maximum growth attributes and yield attributes were obtained with the application of 80 kg P₂O₅/ha + 60 kg K₂O/ha (T₉) and the lowest were observed from 0 kg P₂O₅/ha + 0 kg K₂O/ha (T₁). From the present record it can be concluded that using 80 kg P₂O₅/ha + 60 kg K₂O/ha proved to be more productive and profitable for the cultivation of pea during Rabi season in Manipur climatic condition.
