The objectives were to study effect of plant population and balanced mineral nutrition on productivity and quality of Baby corn. The experiment consisted 16 treatment combinations comprising four plant population (83 K, 111 K, 166 K and 333 K plants ha-1) and four fertility levels (60+30, 90+35, 120+40 and 180+45 kg N+ P2O5 ha-1). These treatments were replicated three times in a randomized block design. Amongst plant population, maintenance of 83 K plants ha-1 accumulated highest dry matter at successive growth stages compared to 111 K, 166 K and 333 K plants ha-1. Plant height was increased as plant density increased from 83 K to 333 K plants ha-1. Crop under influence of 333 K plants ha-1 attained highest LAI compared to 83 K, 111 K and 166 K plants ha-1. Stem diameter was found to be highest at 83 K plants ha-1 compared to 166 K and 333 K plants ha-1 but closely followed by 111 K plants ha-1. Number of ears plant-1 was highest at 83 K plants ha-1 where as 333 K plants ha-1 gave highest ear length. Ear girth decreased with increase plant population from 83 K plants ha-1 to 333 K plants ha-1. Both fresh and dry weight of ears was highest at 83 K plants ha-1 and decreased with increased plant population up to 333 K plants ha-1. Number of barren plants were highest at higher plant densities (333 K plants ha-1). Cob weight with husk was also highest at higher plant population of 333 K plants ha-1. Highest Baby corn, green fodder and biological yield were recorded at 166 K plants ha-1 closely followed by 333 K plants ha-1. Moisture content of ears was high at higher densities where as protein content and carbohydrate content of ears was higher at 166 K plants ha-1. Ascorbic acid content increased up to 166 K plants ha-1ennullThesis
