A field experiment was conducted during the rabi season of 2013 at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, SHUATS, Prayagraj to evaluate the response of row orientation, sowing time, and levels of zinc on growth and economics of sweet corn (Zea mays saccharata). The experiment consisted of twelve treatments comprising of three-row orientations (control, East–West and North-South orientation of sowing), two dates of sowing (22nd October and 06th November) and two zinc levels (20 kg/ha and 30 kg/ha), which were laid out in Randomized Block Design and replicated thrice. The experimental findings reveal the highest plant height, number of leaves/plant, dry weight accumulation, and Crop Growth rate under the treatment T11 (East–West orientation of sowing on 22nd October and applied with 30 kg/ha of Zn/ha). Similarly, the highest number of cobs/plant, cob weight (g), number of grains/cob, and stover yield (t/ha) were recorded under the same treatment T11.
