Response of processing varieties of potato (Solanum tuberosum L.) under varying levels of nutrient in northern hill zone of Chhattisgarh

The present investigation noticed that the “Response of processing varieties of potato (Solanum tuberosum L.) under varying levels of nutrient 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, varieties Kufri Chipsona-1 (V₁) recorded the maximum all growth parameters, yield attributing characters, total tuber yield and quality characters viz. plant emergence (84.74%) plant height (38.27cm), number of shoots plant^-1 (4.98) and number of compound leaves plant^-1 (44.20) on yield parameters, number of tuber plant^-1 (7.48), fresh weight of tuber plant^-1 (259.36 g), tuberization efficiency (2.42) total tuber yield (155.30 q ha^-1 ) and tuber yield<50 g. (14.80 q ha^-1), 50-100 g. (54.14 q ha^-1), >100g. (86.36 q ha^-1 ), dry matter content (22.07 %.), starch content (18.55 %), protein content ( 1.55% ) as compare to Kufri Chipsona-3 (V₂) and Kufri Frysona (V₃) varieties.Among the fertilizer levels 150% RDF (F₃) recorded maximum all growth parameters, yield attributing characters, total tuber yield and quality characters viz. plant emergence (75.56%), plant height (39.87 cm), number of shoots plant^-1 (5.11) and number of compound leaves plant^-1 (47.16), and on yield parameters, number of tuber plant^-1 (7.29), fresh weight of tuber plant^-1 (242.22 g),total tuber yield (134.29 q ha^-1 ), dry matter content (22.69 %), starch content (17.60 %) and protein content (1.53%) which was closely followed by 100% RDF (F₂) and 50% RDF (F₁).
