Evaluation of High Yielding Groundnut Varieties for North Eastern Zone of Tamil Nadu

Groundnut (Arachis hypogaea L.) on farm trials was conducted by Krishi Vigyan Kendra, Kancheepuram to assess suitable drought tolerant groundnut variety in terms of yield, acceptability and adoption potential during Kharif in Kancheepuram district. The study revealed that CO 6 recorded higher pod yield (2850 kg/ha), higher number of pods/plant (32), lesser root rot incidence (3.5%) and optimum plant population (30.6 plants/m²) as compared to ICGV 91114 and Kadiri 9. CO 6, ICGC 91114 and Kadiri 9 recorded 49.4, 16.4 and 23.2 per cent higher yield than the check variety TMV 7, respectively. A reduction in root rot incidence and optimum plant population was observed in all the three varieties as compared to check variety. Gross and net returns were Rs.85, 500/-and Rs.59, 500/-ha, respectively by cultivating CO 6 as against Rs.57, 240/-and Rs.33, 740/-ha in the check variety. Farmers were very satisfied with CO 6, as crop did not suffer from a dry spell of 20–25 days without rain. CO 6 would be a better option for rainfed cultivation in Kancheepuram district.
