A pot experiment was conducted during winter (rabi) season of 2020–21 at research farm of Rajiv Gandhi South Campus (Banaras Hindu University), Mirzapur, Uttar Pradesh to study the effect of NPK on growth and yield attributes of late sown winter baby corn (Zea mays L.). Treatment consisted of 7 levels of recommended dose of fertilizer (RDF) i.e. NPK, viz. control; 20% RDF; 40% RDF; 60% RDF; 80% RDF; 100% RDF; and 120% RDF in completely randomized design, replicated thrice. Each increment in NPK levels, significantly enhanced the growth and yield parameters of baby corn, viz. plant height, leaf area/plant, number of leaves/plant, chlorophyll a and Chlorophyll b, dry weight/plant, first cob harvest and total harvest period, baby cobs/plant, baby corn length and girth, baby cob and baby corn weight, baby cob:baby corn ratio, baby cob, corn and fodder yield (g/plant) up to the highest level than other treatments. The results suggest that late sown winter baby corn can be applied with 150– 75–50 kg NPK/ha for higher yields.
