Abstract
An experiment was conducted in two years (2009/10-2010/11) at Rampur, Chitwan Nepal to study effect of sowing date and varieties on yield of maize. Three varieties namely Rampur Composite, Arun-2 and Gaurav were sown at every week from April to March. The design was randomized complete block design with four replications (week as replication). The result showed that interaction effect of variety and sowing date on grain yield of maize was significant. Rampur Composite and Arun-2 produced highest yield in August and lowest yield in May and Gaurav yielded highest in September and lowest in November. The sowing date was highly significant for grain yield. The highest production was 5.120 tha-1 in August followed by February (4.922 ton ha-1), September (4.626 ton ha-1) and March (4.395 ton ha-1) respectively. The lowest yield was of month May (2.376 ton ha-1).Therefore it was concluded that August planting was best for higher grain production.
