Abstract: Red gram is one of the most important grain legumes in India with 90 % of global production confined within the country. It is largely cultivated and consumed in developing countries and this crop is widely grown in India. The present study has been undertaken to study the performance of different short duration and high yielding Red gram varieties that are suitable for rainfed region of Theni district. The ICAR introduce the on farm testing (OFT) for evaluation of suitable varieties for specific localities to enhance the yield and income of the farmers. A field experiment was conducted in the various farmers field of Theni district, Tamil Nadu during Kharif season 2017-2018. The experimental site is situated in subtropical region. The experimental plot was laid out in Randomized Block Design (RBD) and replicated in thrice with following treatments T₁ - Vellai thuvarai, T₂ - CO 7, T₃ - LRG 52 and T₄ - ICPL 14003. Three improved varieties that are suitable for rainfed region of Theni district was used in this experiment. The recommended dose of fertilizer (RDF) was applied as per crop production guide. The yield and yield attributes viz., number of branches per plant, number of pods per plant, test weight and yield (kg/ha) were recorded. In economics aspect the cost of cultivation (Rs/ha), Gross income (Rs/ha), Net income (Rs/ha) and B: C ratio was analyzed. Among the different varieties of Red gram CO 7 was recorded higher number of branches (13.40) number of pods per plant (255), test weight (9.8 g), lower incidence percentage of pest buildup (13.70) and higher yield (1440 kg/ha). Based on the experiment results, it could be concluded that the CO 7 red gram variety could be considered as a better option for achieving higher productivity and profitability improved quality of Red gram under the rainfed region of the Theni District.
