Abstract:

Studies on Maize seed yield and seed quality response to sowing date during spring in Andhra Pradesh were carried out under field conditions at SRTC, Rajendranagar, Hyderabad during 2012-13. Female (BML 6) and male (BML 7) parents of DHM 117 were sown at fortnightly intervals (from second fortnight of September to second fortnight of December) in 4:1 row ratio in RBD with three replications. Sowing in September second fortnight and October first fortnight recorded significantly more rows cob-1 (16.2 and 15.9), more seeds row-1 (33.1 and 30.7), cob yield plant-1 (120.01 g and 113.36 g), high seed yield plant-1 (92.98 g and 87.09 g) and bold seeds (30.40 g and 29.08 g). At the same time, high germination (96 %) along with long roots (17.1 cm), shoots (12.6 cm), seedling dry weight (0.39 g) and seedling length (29.6 cm) coupled with higher seedling vigor index (SVI I - 2842 and SVI II - 37.5) and field emergence (85 %) was observed during September second fortnight. From the above results, it was concluded that September second fortnight and October first fortnight sowings were better for achieving high seed yield besides realising quality seed.
