Productivity and profitability of maize (Zea mays) cultivars under organic management condition in mid-hills of Sikkim

A field experiment was conducted during pre-rainy (kharif) seasons of 2019 and 2020 at Research Farm ICAR Complex for North Eastern Hill Region, Sikkim Centre, Tadong, Gangtok, to evaluate the performance maize (Zea mays L.) cultivars under organic management condition. Twelve maize, viz. ‘Seti Makkai’, ‘Pahenlo ‘Rato ‘Baiguni ‘Kalo ‘Satheya’, ‘RCM 1–1’, 1–3’, ‘RCM–75’ ‘Vivek Sankul 31’, 37’ 35’ were evaluated system in randomized complete block design. The results showed that cultivar Makkai’ recorded significantly maximum plant height (305 cm) as compared other cultivars. highest dry-matter accumulation (81 g/plant) registered which superior remaining leaf-area index (4.35) minimum days required 50% flowering (61 days) noticed 35’. As cultivars, cob length (16.7 1-1’. 31’ higher girth (13.4 than others. Number rows/cob (12.9) Maximum number grains/row (36.8). grain yield (3.97 t/ha) economic benefits with Short- duration found most promising terms productivity profitability may be recommended cultivation by farmers Himalayas similar agroecoregions production system.
