Abstract:
The present investigation on "Growth and Yield of Potato (Solanum tuberosum L.) as Influenced by Biostimulant under Soilless Culture System," was conducted in the glasshouse at Bidhan Chandra Krishi Viswavidyalaya, Department of Vegetable Science, Faculty of Horticulture, during the year 2020-21. The purpose of this study was to investigate six commercial varieties of potato in order to identify the most suitable variety and to investigate the best biostimulant under soilless culture system. The experiment was laid out in Completely Randomized Design with three replications. The treatment consists of six varieties viz. (Kufri Jyoti, Kufri Chandramukhi, Kufri Himalini, Kufri Gaurav, Kufri Khyati, Kufri Pokhraj and two biostimulants pilatus (@ 1 ml/lt water) and goldstar (standard dose @ 2 g/li water) cultivated in the growing media- cocopeat, vermicompost, perlite and their 1:1:1 mixture. From the investigation it was observed that. Kufri khyati had the highest plant height (58.170 cm at 60 DAP and 61.233 cm at 90 DAP), the most tubers per plant (19.437) and the largest tuber diameter (6.667 cm) and the highest total yield per plant (1.303 kg/plant).All of these yield-related characteristics were discovered to be most effective in plants treated with Pilatus biostimulant. In terms of quality parameters, the variety Kufri Pokhraj contains the most total sugar (0.77%) and reducing sugar (0.512%). The variety Kufri Jyoti had the highest total soluble solids (7.115 o Brix). When it comes to quality parameters, goldstar exhibits the maximum values of total sugar (0.535%), reducing sugar (0.389%), total soluble solids (5.455⸰Brix). Pilatus biostimulant was found to be most effective for growth and yield attributing characters whereas goldstar was found effective for quality traits. Overall it concluded that variety kufri khyati in application of Pilatus is best combination for cultivation of potato under soilless culture systems.
