Field trials show improved grain yield in maize with specific sowing dates, indicating optimal planting times may enhance productivity.
The field experiment, conducted at ZARS, V.C. Farm, Mandya during kharif season, was laid out in a split plot design where main plots were assigned to four sowing dates (August 1st fortnight, August 2nd fortnight, September 1st fortnight and September 2nd fortnight) and sub-plots to three cultivars of maize (MAH 14-138, MAH 14-5 and Bio 9544), with twelve treatment combinations and replicated thrice. The results revealed that, D1 (August 1st fortnight) sowing recorded higher cob length (17.19 cm), cob girth (8.83 cm), test weight (32.59 g), grain yield (7355 kg ha-1) and stalk yield (10647 kg ha-1). Among different cultivar H2 (MAH 14-5) recorded higher cob length (17.47 cm), cob girth (8.75 cm), test weight (31.99 g), grain yield (6967 kg ha-1) and stalk yield (10075 kg ha-1).
