Abstract:
An experiment was taken up to assess the effect of seed coating polymers in combination with fungicide and biocontrol agent on field performance of groundnut variety Kadiri-6. The trial was laid out in randomized block design with three replications at Seed Research and Technology Centre, Hyderabad during kharif, 2019. Analysis of variance revealed the presence of significant differences among the treatments studied. The results showed that seed treatment with polymer-1 + tebuconazole + Trichoderma harzianum was found to be significantly superior for plant height, number of branches per plant, number of pods per plant, pod yield per plant, kernel weight per plant and pod yield per ha compared to control. The treatments such as polymer-2 + tebuconazole + Trichoderma harzianum and polymer-1 + tebuconazole were showed superiority for some of the yield components. Low disease incidence of collar rot and low disease severity of tikka leaf spot and rust disease were observed in polymer-1 + tebuconazole + Trichoderma harzianum followed by polymer-2 + tebuconazole + Trichoderma harzianum and polymer-1+tebuconazole. Use of quality seed is one of the best ways to exploit the potential of the varieties. Based on the study, it is suggested that seed treatment with polymer, fungicide and biocontrol agent could be used to realize higher yields in groundnut.
