Performance of groundnut varieties for better yield in nagapattinam district of Tamil Nadu

The present study was conducted during kharif 2017 in three villages of Nagapattinam district to assess the suitable variety of Groundnut. Five farmers’ field were randomly selected and sown three high yielding improved varieties of groundnut namely Kadiri 9, CO 6 and ICGV 91114 with five replications with one check variety already grown by the farmers. The study revealed that Kadiri 9 recorded higher pod yield (19.87 q/ha), higher number of pods/plant (21.12), lesser root rot incidence (4.30%) and optimum plant population (33.02 plants/M²) as compared to CO 6 and ICGV 91114. Kadiri 9, CO 6, and ICGV 91114 recorded 35.15, 27.10 and 18.89 per cent higher yield than the check variety TMV 7, respectively. A reduction in root rot incidence, leaf minor, leaf spot, Spodoptera damage and optimum plant population was observed in all the three varieties as compared to check variety. Gross and net returns were Rs.1,19,220/- and Rs.73,990/-ha, respectively by cultivating Kadiri 9 as against Rs.77,280/- and Rs.37,824/-ha in the check variety. Hence, it was inferred that Kadiri 9 variety of ground nut proved better followed by CO 6 and ICGV 91114.
