Neupane S., Karn R., Khanal P., Karki S., and Sah S.K., 2019, Performance of maize hybrids in spring season at Sonpur, Dang, Nepal, Field Crop, 2(4): 21-27 (doi: 10.5376/fc.2019.02.0004)

A field experiment was conducted to assess the performance of maize hybrids during the spring season of 2019 at Lamahi, Dang, Nepal. The treatments consisted of two maize hybrids from Nepal registered as pipeline varieties viz. RML 95/96 and RML 86/96 and four commercial multinational hybrids viz. P3396, P3522, 10V10 and X5. The experiment was conducted in RCBD with three replications. The data was analyzed using MSTATC and Zenstat fifteenth edition. Plant height was insignificant among the varieties at all dates of observation except at 75 DAP and at harvest. 10V10 recorded significantly lower plant height at both dates of observation. The Number of leaves was also non-significant among the hybrids tested at all dates of observation. Although number of ears harvested per ha were found non-significantly different among the hybrids, multinational hybrids recorded numerically higher number of ears. Other yield attributing characteristics viz. thousand kernel weight, number of kernels per ear, shelling percentage, kernels per row was found significantly higher in multinational hybrids compared to Nepalese hybrids. Grain yield was found significantly higher in multinational hybrids with 10V10 maize hybrid recording yield of 12.85 t ha^-1 closely followed by P3522 (11.65 t ha^-1), P3396 (11.59 t ha^-1) and X5 (10.62 t ha^-1) whereas Nepalese hybrids RML 95/96 and RML 86/96 recorded grain yield of 8.35 t ha^-1 and 8.30 t ha^-1 respectively. Therefore, selection of maize hybrids for thousand grain weight, number of ears harvested, kernels per ear and cob length could help in improving maize grain yield.
