Excessive nitrogen (N) mining coupled with negligence of external application of N sources in rainfed eco-system is widespread at farmers field for achieving higher productivity of pulses and N-use efficiency. The objective of this research was to explore the possibility of nitrogen nutrition to rainfed pulses grown on highly N deficient acidic upland red soil in Mirzapur district of Vindhyan zone, India. Field experiments were conducted separately on major rainfed pulses viz; greengram, blackgram and pigeonpea during Kharif season of 2018 under rainfed area of Mirzapur in Vindhyan zone, India. The present study comprised of ten treatments consisting of two levels of N, lime and biofertilizer either alone or different combinations including control. The treatments were replicated thrice in randomized block design. The results revealed that grain yields and agronomic use efficiency of greengram, blackgram and pigeonpea were improved considerably due to conjunctive application of the recommended dose of phosphorus and potassic fertilizers (RDPK), 40 kg N ha-1, lime and Rhizobium together over absolute control. Application of  lime and Rhizobium resulted in an increase of N use efficiency which was  higher at applied lower level (20 kg N ha-1) as compared to higher level of N (40 kg ha-1). Grain protein content of greengram, blackgram and pigeonpea were  increased greatly up to 23.41, 24.56 and 22.55 per cent under application of 40 kg N ha-1, lime and Rhizobium along with RDPK application over unfertilized control (22.1, 22.85 and 20.9%), respectively. Results further indicated that, amino acids (cysteine and methionine) content of pulses grain were improved appreciably due to nitrogen, lime and Rhizobium application
