In Nepal, the overwhelming majority of the poor live in rural areas where they face poverty, hunger and acute challenges of food insecurity. The population is increasing and so is the number of mouths that demands food. To feed this growing population, agriculture production needs to be increased. With the agricultural land being used for other purposes, rather than cultivation, vertical expansion of land with its scientific cultivation method remains the sole factor to support the agriculture production. This research was carried out to explore the ideas of genetic variability of early maize to determine the best early maize genotype for hilly Nepal, which for some extent can help to meet the food demand of people.
