The experiments were carried out during zaid seasons of 2014 and 2015 at Crop Research Farm, Block E of SHUATS Model Organic Farm (SMOF), Department of Agronomy, Allahabad School of Agriculture, SHUATS, Allahabad, and Uttar Pradesh, India. The objective was to study the influence of short duration legume intercrops and organic nutrient management practices on growth, yield, and quality, nutrient status of the soil and nutrient uptake of baby corn and component crops under certified organic production system. Short duration intercrops [greengram (Vigna radiata L.) and clusterbean (Cyamopsis tetragonoloba L.)] along with control (no intercrop) were taken in main plot. Different sources of organic manure and their combination [goat manure (M1), poultry manure (M2), FYM (M3), goat manure + poultry manure (M4), goat manure +FYM (M5) and poultry manure +FYM (M6)] were assigned to sub plot in a split plot design, the experiments were replicated thrice. Results of the experiments revealed that sole cropping of greengram under different treatments of organic manures gave significantly higher number of branches, leaf area index and number of nodules per plant during both the years and pooled analysis as compare to intercropping with baby corn. Intercropping of greengram with baby corn decreased the yield and yield attributes of greengram by 7.13% as compare to sole cropping. However, this marginal loss was compensated by additional harvest of baby corn crop. Among the manurial treatments significantly maximum number of branches per plant and leaf area index was recorded in treatment M6 and M2 due to application of poultry manure alone or either in combination with FYM. While, different sources of organic manures did not affect the number of nodules per plant of greengram during both the years and pooled analysis. Yield attributes and yield of greengram was increased in M2 (Poultry manure at the rate of 1.92t ha-1) and M6 (Poultry manure at the rate of 0.96t ha-1 +FYM at the rate of 5t ha-1) respectively, as compared to rest of the manurial treatments.
