Dhakal B., Bhusal T.N., Acharya S., and Bist D., 2024, Evaluation of potato varieties for yield and yield components in Myagdi, Nepal, International Journal of Horticulture, 14(6): 333-342 (doi: 10.5376/ijh.2024.14.0034)

An experiment was conducted between February and June 2022 in Annapurna Rular Municipality, Myagdi, Nepal with an objective to assess various potato varieties for their yield and yield components. The experiment followed a randomized complete design with five treatments (Desiree, Janakdev, Kufri Jyoti, Mustang local, and Myagdi local) each replicated four times. Growth parameters, including plant height (cm), number of leaves per plant, number of stems per hill, and canopy diameter (cm) at various days after planting, were measured. Yield parameters such as tuber weight per plant (g), tuber number per plant, marketable tuber (kg/m²), Unmarketable tuber (kg/m²) and tuber distribution by grading in terms of number and weight were recorded. Additionally, disease scoring was done for severity and incidence of potato wart on potato varieties. The results indicated that Janakdev exhibited the tallest plant (66.00 cm), while Desiree had the shortest (47.50 cm). Janakdev also displayed the maximum number of leaves per plant (76.90), whereas Desiree had the minimum (50.55). Desiree and Myagdi local recorded the highest (5.53) and lowest (3.50) number of main stems per hill, respectively. Myagdi local demonstrated the maximum canopy diameter (55.15 cm), while Desiree had the minimum (43.91 cm). Janakdev showed the highest tuber weight per plant (512.73 g) and the highest tuber number (8.50). Mustang local produced the highest number of small-sized tubers (25 mm), with Janakdev recording the highest number of large-sized tubers (>50 mm). In terms of yield, Janakdev yielded the highest (37.93 t/ha), whereas Mustang local had the lowest yield (12.27 t/ha). Highest incidence of potato wart was found on Myagdi local (Seto aalu) about 98%. Given its superior performance across various growth and yield traits, Janakdev demonstrated high yield potential (337.93 t/ha) in khibang-06, Myagdi, Nepal. Consequently, Janakdev was recommended as the most suitable variety for farmers in khibang-06, Myagdi.
