Abstract
Finger millet (Eleusinecoracana) is the major staple food crop cultivated in rain fed and irrigated condition in the zone of North Eastern Region of Tamil Nadu. However the productivity of the crop is affected by blast disease caused by Magnaporthe grisea and lack of high yielding varieties. An investigation was made to identify suitable high yielding and blast resistant varieties through on farm trials in Velloredistrict during 2017–18. The results of the study revealed that TNAU Finger millet Co15 recorded the higher plant height (128 cm), number of tillers per plant (8.0), number of ear head per square meter area (76.2). The reaction to the blast incidence was moderately resistant to leaf blast with the disease score of 2.1. The per cent incidence of neck and finger blast was 5.2 and 5.7, respectively against ruling variety GPU 28 which recorded 14.3 and 19.2 per cent. The maximum grain yield (2268 kg/ha) was recorded in finger millet CO15followed by ML 365. The feedback from the farmers also revealed exultant with CO 15 due to its high tillering per plant, more number of ear head per square meter and moderately resistant to blast disease and high yielding nature. The economical parameter such as maximumnet income of Rs.44,850/ha and benefit cost ratio of 2.93 was recorded in CO 15 compared to the other finger millet varieties. Considering the above facts, CO 15 would be a better option to the farming community for enhancing the productivity of finger millet in North Eastern Zone of TamilNadu.
