Abstract:
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 with only FYM application Significant variation was witnessed among sowing dates regarding dry yield of sweet corn. While, it also varied significantly among the hybrids. Among the main-plot treatments sowing on 2nd July (S1) (2.44 tha-1) exhibited highest grain yield and was significantly superior over remaining treatments. While it was followed by S2 (1.87 t ha-1) and S3 (1.39 t ha-1). Among the sub-plot treatments ASKH-6 (V3) witnessed significantly highest dry yield with (3.34 t ha-1) followed by ASKH-1 (V1) (2.04 t ha-1). Data obtained for post-harvest nutrient availability was found to be non-significant among the main-plot treatments. However, among sub-plot treatments highest available nitrogen was registered by ASKH-4 (V2) (232.11 kg ha-1) followed by V4 and V1. While highest value for available phosphorous was recorded by ASKH-4 (V2) (19.56 kg ha-1) followed by V4 and V1. Available potash (K) was found to be highest in ASKH-4 (V2) (382.91 kg ha-1) which was statistically at par with V4. Delay planting reduced dry grain yield and the length and diameter of cob.
