Abstrakt: An investigation was carried out to optimize the planting ratios between female (CAL 1443) and male (CML 451) parents to maximize seed yield and quality of single cross hybrid maize, MAH 14-5 during Summer 2018. The study consisted of five planting ratio of male and female with zinc application at the time of sowing. Planting ratios, zinc nutrient and their interaction showed non-significant differences for growth parameters viz., plant height, number of leaves per plant, days taken to 50 and 100 per cent tasseling and silking in male and female respectively. The planting ratio of 4:2 significantly recorded maximum ear weight (141.63g), ear diameter (4.65 cm), ear length (18.55 cm), number of seed rows per ear (16.13), number of seeds per row (28.13), seed weight per ear (115.75g) and seed yield per plant (135.49g) in seed parent but, 4:1 showed significantly higher seed yield per plot (8.96 kg) and seed yield per ha (35.10q). However, number of ears per plant and pith weight showed non-significant for planting ratios. Zinc nutrient and interaction of planting ratios and zinc nutrient showed non-significant for all the yield parameters. Quality parameters viz., hundred seed weight, germination, seedling length, seedling dry weight, seedling vigour index I and seedling vigour index II showed non-significant differences for planting ratios, zinc nutrient and their interaction.
