Effect of Nitrogen, Zinc and Iron on Growth and Yield of Baby-corn (Zea mays L.) Prayagraj Condition

A field experiment was conducted at the Crop Research Farm (CRF), Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (UP) during the year 2021 zaid season. To find out suitable Nitrogen, zinc and iron levels for profitable baby corn yield. The experiment comprised of 9 treatments with different combinations of nitrogen, zinc and iron replicated thrice in a Randomized Block Design. The main objective of the experiment was to evaluate the Effect of Nitrogen, Zinc and Iron on growth and yield of baby-corn (Zea mays L.). The nitrogen levels include [70, 80 and 90 kg/ha] where-as levels of zinc (0.5%) and iron (0.2%) From the present investigation The results showed that viz: Plant height (169.75 cm),Number of leaves per plant (13.80) plant dry weight (113.09 g/plant) were recorded significantly higher in 90kg/ha Nitrogen along with 0.5% Zinc and 0.2% Iron. Number of cobs per plant (1.69), cob length (18.50 cm), cob girth (8.10cm), cob weight with husk (48.85g), cob weight with out husk (13.80 g), cob yield with husk (11.75 t/ha), cob yield without husk (4.35 t/ha), green fodder (33.58t/ha) and the profitable production of baby corn can be secured by 90kg/ha Nitrogen + [0.5% Zinc + 0.2% Iron].
