| dc.description.abstract | The present investigation was carried out in two field experiments, one being the staggered sowing to study synchronization of flowering between female (CAL 1443) and male (CML 451) parents of single cross hybrid maize, MAH 14-5 during kharif 2017. The experiment was laid out in RCBD design with five treatments and four replications. The female and male parents sown on same day (S3) showed better synchronization in flowering which in turn resulted significant enhancement in yield parameters like ear length (18.33 cm), number of seeds per row (28.15), ear weight (140.35 g), seed weight per ear (115.75 g), seed yield per plant (140.10 g), seed yield per plot (2.24 kg) and seed yield per ha (34.09 q) in female parent. Another experiment was carried out to optimize the planting ratios during summer 2018. The experiment was laid out in split plot design with five main plot treatments (planting ratios) and two sub plot treatments (zinc nutrient). Planting ratio of 4:2 (female : male) registered significantly higher values for ear weight (141.63 g), 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 (115.75) and seed yield per plant (135.49 g) in seed parent. However, significant differences for seed yield per plot (8.96 kg) and seed yield per ha (35.10 q) was observed in 4:1 planting ratio. Hence, the study concluded that the sowing of male and female parents on same day with planting ratio of 4:1 could achieve better synchronisation of flowering in parents higher seed quality attributes and yield of seed parent. | en_US |
