The field experiment was conducted at Regional Research Station, S.D. Agricultural University, Bhachau, Kachchh to evaluate the effect of different levels of FYM, phosphorus and nitrogen on yield and economics of moth bean [Vigna aconitifolia L.] during Kharif season of 2017-18, 2019-20 and 2020-21. The experiment consists of eighteen treatment combinations comprised of two FYM levels [0 t/ha (F0) and 2.5 t/ha (F1) combined with three phosphorus levels [0 kg P₂O₅/ha (P₀), 20 kg P₂O₅/ha (P1) and 40 kg P₂O₅/ha (P2)] along with three levels of nitrogen [0 kg N/ha (N₀), 20 kg N/ha (N1) and 40 kg N/ha (N2)]. Phosphorus applied in the form of PROM and nitrogen in form of urea. The experiment was laid out in factorial RBD with three replications. The results revealed that seed and stover yields of moth bean were significantly increased by the FYM, phosphorus and nitrogen treatments. The increased in seed yield due to F1 over F0 (698 kg/ha) increased in seed yield by 13.46 per cent. The treatment P2 and P1 over P0 (776 kg/ha) was 21.92 and 13.51 per cent, respectively and treatment N2 and N1 over N0 (783 kg/ha) was increased 23.35 and 10.93, respectively. Similar trend in stover yield was noted by FYM, phosphorus and nitrogen treatments. The interaction of P X N effect was significant on seed and Stover yields indicate that nutrient use efficiency of P was higher when phosphorus was applied along with organic FYM @ 2.5 t/ha and nitrogen @ 20 kg N/ha. The interaction of P X N effect was significant on seed and stover yields indicate that nutrient use efficiency of P was higher when phosphorus was applied along with organic FYM @ 2.5 t/ha and nitrogen @ 20 kg N/ha. Treatment combination F1P2N2 (FYM @ 2.5 t/ha, 40 kg P₂O₅/ha and 20 kg N/ha) was obtained significantly higher nutrients uptake by seed and stover. Available nutrients in the soil after harvest are best in the F1P2N2 (FYM @ 2.5 t/ha, 40 kg P₂O₅/ha and 20 kg N/ha) maintained the soil physico-chemical properties. The application of FYM @ 2.5 t/ha with phosphorus @ 40 kg P₂O₅/ha and nitrogen @ 20 kg N/ha secured the higher net realization of 23853, 26076 and 23626 /ha, respectively.
