Abstract: The combined effect of organic and inorganic nutrient sources on short grain aromatic rice-greengram cropping system was carried out during kharif and rabi seasons in 2017-18 and 2018-19. Pooled analysis showed that nutrient management by 50% RDF + 50 % RDN through FYM recorded significantly higher grain yield (3875 kg ha-1), straw yield (7233 kg ha-1), hulling (75.7 %), milling (66.7%), head rice recovery (59.8%) and protein content (9.0%). Application of 50% RDF + 50 % RDN through FYM to preceding rice recorded significantly higher seed yield (806 kg ha-1), stover yield (1957 kg ha-1) and harvest index (29.1 %) in greengram. Application of 75% RDF+ Rhizobium+ PSB to greengram crop recorded significantly higher seed yield (697 kg ha-1), stover yield (1787 kg ha-1), harvest index (28.2 %). Significantly higher nitrogen uptake (165.5 kg ha-1), phosphorus uptake (30.1 kg ha-1) and potassium uptake (217.3 kg ha-1) in cropping system were recorded with application of 50% RDF+ 50% RDN through FYM to rice.
