Response of potato cultivars (Solanum tuberosum L.) under different nitrogen levels in northern hill zone of Chhattisgarh

Abstract

The present investigation noticed that the “Response of potato cultivars (Solanum tuberosum L.) under different nitrogen levels in northern hill zone of Chhattisgarh” was carried out at the research farm of Potato and temperate fruit research station, Mainpat, Surguja (C.G.) during Rabi of 2024-25, cultivars Kufri Khyati (C1) recorded the maximum all growth parameters, yield attributing characters and total tuber yield viz. plant emergence (90.71%) plant height (39.42cm), number of shoots plant-1 (7.25) and number of compound leaves plant-1 (42.39) on yield parameters, number of tuber plant-1 (8.35), fresh weight of tuber plant-1 (335.93 g), tuberization efficiency (2.31) total tuber yield (184.76 q ha-1) and tuber yield100g (120.88 q ha- 1) as compare to Kufri Kanchan (C3) and Kufri Karan (C2) cultivars. On quality characters maximum dry matter content (22.72%.) in Kufri Kanchan (C3) as compare to Kufri Karan (C2) and Kufri Khyati (C1) cultivars, maximum starch content (17.46%) in Kufri Karan (C2) as compare to Kufri Khyati (C1) and Kufri Kanchan (C3) cultivars, maximum protein content (1.79%) in Kufri Karan (C2) as compare to Kufri Kanchan (C3) and Kufri Khyati (C1) cultivars. Among the nitrogen levels 225 kg ha-1 (N3) recorded maximum all growth parameters, yield attributing characters, total tuber yield and quality characters viz. plant emergence (78.77%), plant height (38.35 cm), number of shoots plant-1 (5.27) and number of compound leaves plant-1 (39.46), and on yield parameters, number of tuber plant-1 (8.45), fresh weight of tuber plant-1 (334.81 g), total tuber yield (168.16 q ha-1), dry matter content (22.31 %), starch content (16.09 %) and protein content (1.54%) which was closely followed by 150 kg ha-1 (N2) and 75 kg ha-1 (N1).
