Performance analysis of potato seed production at different agroclimatic regions of Bihar

Regional performance of potato seed

Abstract

The major drawback to higher potato productivity in Bihar is the non-availability of quality and disease-free potato seeds. However, the aeroponic system followed by adopting the SPT method is a potential method for obtaining good quality seed tubers. Therefore, in this study, the potato mini-tubers that were produced under the Aeroponic system viz., Yushimap, Bari Aloo-7015, Kufri Thar-2, Kufri Neelkanth, Kufri Mohan and Kufri Lima were evaluated at all 18 locations of Bihar. Results revealed that the different varieties expressed significant differences in their productivity at different locations. The varieties Yushimap and Bari Aloo-7015 performed better at all locations therefore, these varieties have an ability of higher yield potential under agro-climatic conditions of Bihar. The varieties such as Kufri Thar-2, Kufri Neelkanth, Kufri Mohan and Kufri Lima performed better than local varieties in terms of heat, moisture, disease and pest tolerance. The study indicates that these new potato varieties may manifold potato productivity and encourage potato growers and entrepreneurs to expand quality seed production businesses in Bihar.
