“…Tuber yield is a complex trait, affected by genotype and environmental factors (Struik & Wiersema, 1999). Luitel et al (2016) reported a marketable tuber yield variation of 7.6 to 24.0 tha -1 at high hills of Nepal and similar tuber yield variation were reported on potato by different researchers in Nepal (Luitel et al 2017a;Gainju et al 2019). In addition to the genotypic effect, differences in tuber size, plant spacing and weather variations could have caused the yield variation among the genotypes (Masarirambi et al 2012).…”

A field experiment was conducted at Horticulture Research Station (HRS), Dailekh, in Mid-Western hills of Nepal during 2019 and 2020, to evaluate the performance of ten potato genotypes for plant, and tuber yield characters. The potato genotypes were evaluated during spring season in a randomized complete block design with three replications. The genotypes showed highly significant difference for all the traits except tuber emergence. The mean squares for the year were also significant for all the traits except tuber emergence, stem numberplant -1 and total tuber yield. The interaction between genotypes and years did not show significant differences in all the traits except stem numberplant -1. Genotype CIP392797.22 produced more marketable yield (27.5 tha -1) and total tuber yield (30.2tha -1) than all other genotypes. The genotype CIP392797.22 is characterized as medium maturing, oval-shaped and dark red-skinned one with shallow eye depth in the tuber, and it imparted 13.2% higher marketable yield than Kufri Jyoti (24.3 tha -1). Thus, the genotype CIP392797.22 is recommended to evaluate on-farm for the verification and up-scaling among farmers at Mid-Western Nepal.

“…Seifu and Betewulign (2017) also reported a significant difference in total tubers plant -1 among potato varieties. Tuber weight is an important yield component of potato that contributes to total tuber yield (Morena et al 1994;Luitel et al 2017a). Variation in marketable tuber weight among the genotypes may be due to genetics.…”

The purpose of the study was to analyze the value chain of potato in the Ilam district. Potato is one of the major stable food and source of income for the majority rural farmers of the Ilam district. Using random sampling techniques, data were collected using semi-structured household survey with 165 respondents, 50 traders, input and service providers and along with 5 focus group discussion. Data were analyzed using SPSS and excel software. Results of the compound annual growth analysis showed that area, production and productivity is increasing significantly by 8.12, 2.87 and 2.79% respectively over 19 years in the country and 3.78, 2.84, and 3.55 respectively in the Ilam district. The farmers are generally growing local variety however; they also grow some improved varieties. The benefit cost ratio of local varieties is very low (0.68) whereas for improved varieties higher (1.73). Farmers do not adopt the grading and packaging which is generally done by the traders. The import of potato sharply increasing over the years which was 46,097 t worth of NPR 35.74 million in 2008/09 and reached to 249,368 t worth of NPR 531.25 million in 2016/17 which is 14.86 fold increases in value within 8 years. The value chain analysis reveals that, the margin received by the farmers is 27% of the retail price whereas traders and wholesalers deals in big quantities and extract substantial margin. The major constraints of potato production are diseases accompanied by weak availability of seed, high production cost, decreasing labor availability, and weak backward and forward linkage. Therefore, findings suggest that, government and developing agencies should support farmers organizations for the adoption of new variety, Shrestha and Yadav; SAJSSE, 2(3): 1-13, 2018; Article no.SAJSSE.46158 2 involve in quality seed production, integrated management of diseases, reduce cost of production, develop agricultural marketing infrastructures to boost up the production and make market access to the farmers.

Potato is one of the major crops of Nepal and postharvest loss is one of the major problems in the potato value chain system. Therefore, this study was conducted with the objective of assessing post-harvest losses of potato under farmers’ storage conditions. Potato tubers of six potato genotypes (three released varieties viz. ‘Jankdev’, ‘Khumal Upahar’ and ‘Khumal Vikash’ and three pipeline genotypes viz. ‘CIP 393073.179’, ‘CIP 395112.32’ and ‘Techno 304351.109’) were evaluated in randomized complete block design with three replications under four different farmers’ storage conditions at Panauti-8, Kavrepalanchok district of Nepal from May to August 2019. The tubers were cured after harvesting for two weeks in a shade, thereafter they were stored for 80 days. Data were recorded on 20, 40, 60, and 80 days of storage. The results showed that at 80 days of storage, the lowest weight loss (5.51%) was found in Techno 304151.109 followed by CIP 393073.179 (6.68%). Potato tuber moth infestation was minimum in CIP 393073.179 (1.15) followed by Techno 304151.109 (1.25). The days to sprouting was the highest in CIP 393073.179 (69.25) followed by Techno 304151.109 (68.75). No shrinkage was observed in CIP 393073.179 and Techno 304151.109 till 60 days of storage. Loss due to rotting was not observed in these genotypes. Therefore potato genotypes CIP 393073.179 and Techno 304351.109 were promising for their storability in farm conditions; which can be recommended for commercial production in the mid-hill environment of Nepal.
