Abstract: The on farm testing (OFT) experiment was conducted at farmer field of Srirengapuram village, Theni, Tamil Nadu during Kharif 2018 -2019. The experiment trail was conducted to assess the performance of high yielding Castor hybrids for rainfed region of Theni district. The experiment was laid out in a randomized block design and replicated thrice with following four treatments; T₁ - Farmers practice (Local nettai), T₂ - YRCH 2, T₃ - DCH 177, T₄ - DCH 519. There are three hybrids namely, YRCH 2, DCH 177 and DCH 519 was used in this experiment trail. The recommended doses of fertilizer (RDF) were applied at the time of field preparation as a basal dose. The yield and yield attributes viz., number of spikes per plant, number of capsules per spikes and yield (kg ha^-1) was recorded. In economics aspect the cost of cultivation (Rs.), Gross income (Rs.), Net income (Rs.) and B: C ratio were analyzed. Among the different treatments YRCH 2 resulted higher number of spikes per plant (39.6), number of capsule per plant (44.0), yield (1867 kg ha^-1). Based on the experimental results, it could be concluded that YRCH 2 Hybrid could be considered as a better option for achieving higher productivity and profitability and improved quality of Castor under the rainfed region of Theni District.
