A field experiment was conducted during kharif season of 2018 at the College of Agriculture, Kyrdemkulai, (Central Agricultural University, Imphal), Ri-bhoi district, Meghalaya to evaluate the sweet corn hybrids under varied date of sowing in mid hill of Meghalaya. The experiment was carried out in a split plot design with three numbers of main- plot treatments, viz., sowing date on 2nd July (S1), 12th July (S2) and 22nd July (S3) four numbers of sub- plot treatments, viz., ASKH-1 (V1), ASKH-4 (V2), ASKH-6 (V3) and SWEET-77 (V4) and replicated thrice. Among the main-plot treatments (S1) exhibited highest cob yield (6.59 t ha-1) and stover yield (9.97 t ha-1) was significantly superior over remaining treatments. While, among the sub-plot treatments (V3) witnessed significantly highest cob yield with (6.20 t ha-1) followed by (V1) (5.60 t ha-1), (V4) (4.89 t ha-1) and (V2) (4.40 t ha-1). Sowing done in 2nd July (S1) registered the highest LAI followed by 12th July (S2) and 22nd July (S3) at 30, 45, 60 and 75 DAS. Significantly the highest LAI was witnessed by ASKH-6 (V3) among all the sub-plot treatments of sweet corn hybrids at 30, 45, 60 and 75 DAS. ASKH-6 was proved to be best among all the four hybrids while 2nd July was found to be superior among all sowing dates because further delay of sowing has negative effect on the performance of the hybrids.
