A field experiment was conducted during 2014-15 and 2015-16 on Research Farm of Division of Agronomy, IARI at New Delhi to evaluate Influence of crop residue and potassium management on yield, quality, nutrient uptake and K use efficiencies of mungbean in maize-wheat- mungbean cropping system. The experiment consisted of 15 treatment combinations with three crop residues [no crop residue, crop residue incorporation and fungal consortium incorporation] and five potassium management practices [control, KSB, 100 % RDK, 50% RDK+ KSB and 75% RDK+ KSB]. Results revealed that considerably highest grain yields, protein content, protein yield and N P K concentration both in seed and stalk and its uptake by mungbean were noticed with treatment receiving crop residue incorporation + fungal consortium which was statistically at par with crop residue incorporation. Similar trends were also recorded for K use efficiency, physiological use efficiency, apparent recovery and utilization efficiency during both years of study. Among Potassium management, significantly highest grain yield, protein content, protein yield, N P K concentration, uptake in both seed and stalk and its total uptake were noticed with treatment receiving 75% RDK + KSB which were statistically at par with 50% RDK+ KSB. However, maximum K use efficiency, physiological use efficiency, apparent recovery, utilization efficiency were noticed with treatment receiving 50% RDK+ KSB which were statistically at par with 75% RDK+ KSB as compared to the first year, maximum attributes and efficiencies were observed in the second year of investigation.
