Baby corn is an exhaustive cereal in terms of nutrients absorbance from soil and thus soil become easily loss it’s beneficial physical and chemical properties. To maintain soil health during cereal production like baby corn both chemical and organic sources of fertilizers can be used, thus a study was executed at the agronomy field of Bangladesh Agricultural University, Mymensingh in the year of 2017-2018 to find out the growth performances and their impact on corn yield of baby corn as affected by varieties and different sources of nitrogen fertilizer. The experiment was conducted in Randomized Completely Block Design with three replications with two factors where two varieties viz., BARI Sweet corn-1 (V1) and Baby star (V2) acted as Factor A and five sources of nitrogen fertilizer viz.,100% recommended N from urea (N1), 75% N from urea + 25% N from cowdung (N2), 50% N from urea + 50% N from cowdung (N3), 75% N from urea + 25% N from poultry manure (N4), 50% N from urea + 50% N from poultry manure (N5) acted as Factor B. The highest plant height (153.0 cm), number of leaves per plant (7.33), leaf chlorophyll content (SPAD value 38.68), (TDM) (40.60 g plant-1), corn yield (3520 kg ha-1) were recorded in the interaction between Baby star when fertilized with N2 (75% N from urea + 25% N from cowdung). All the growth parameters showed strong positive correlation with corn yield. The highest harvest index (0.075) was observed when BARI Sweet corn-1 was cultivated with N2 (75% N from urea + 25% N from cowdung). Therefore, it may be concluded that for better growth performance and for better corn yield Baby star is the promising baby corn variety when cultivated with (75% N from urea + 25% N from cowdung) for better growth performances and maximization of baby corn yield.
