Increased awareness of environmental degradation and growing concern of human health has attracted worldwide
attention towards organic farming. A field experiment was carried out during kharif of 2013–2014 to identify suitable
maize (Zea mays L.) cultivars having high yield potential under organic production system. Twelve released cultivars
of maize varied in duration and nitrogen requirement were evaluated. Results revealed that late maturing cultivars
PMH-1 and PMH-3 being at par to each other recorded the significantly higher values of growth parameters like plant
height, dry matter accumulation and leaf area index; and yield attributes in terms of cobs plant, cob length, cob girth,
grain rows/cob, grains/row and test weight, whereas the extra early cultivars like Vivek QPM-9 being at par with
Vivek Hybrid-9 registered the lowest values of growth and yield attributes. The late maturing cultivars like PMH-1,
PMH-3, Seed tech-2324 and Bio-9681 produced significantly higher grain yield (>5.0 t/ha) and biological yield (>12.5
t/ha). Cultivars PMH-4 among medium maturity group produced comparable yield with late cultivars. Grain yield
across the varied duration cultivars had a significant positive correlation with cob length, grains/row and N uptake. As
per their maturity class, the extra early and early cultivars commence silking (
