Abstract
The studies were carried out at the School of Agricultural Sciences and Rural Development, Medziphema campus, Nagaland University during 2019. The experiment was laid out in a Split Plot Design (SPD) having three replications. The cultivars viz., Zarsi, Sipho, Ronimi, Khoi and HQPM-1 were sown on 3 different dates i.e., 6th March, 21st March and 5th April. Among the five cultivars used the local cultivar ‘Sipho’was found to be the most tolerant and performed better than the composite variety ‘HQPM-1’ and the different dates of sowing, 5th April was found to be the most successful with the least infestation by Chilo partellus. The maize sown on 21st March recorded the highest grain yield (4.12 t/ha). Among the four cultivars and one composite variety evaluated, the highest grain yield was recorded from cultivar Sipho with 4.13 t/ha, while the lowest from cultivar Ronimi with 3.11 t/ha.
