“…Significant variations of potato varieties in tuber yield were also reported [36]. A similar result of the differential performance of total tuber yield (t/ha) of potato was reported [37][38][39][40].…”

Coordinated Varietal Trial (CVT) on different genotypes of potato received from National Potato Research Program (NPRP), Khumaltar, Lalitpur was carried out at Horticultural Research Station, Rajikot, Jumla at an altitude of 2396 m above mean sea level during two consecutive years 2019 and 2020 to evaluate potato genotypes suitable for the high hills of Karnali province of Nepal. Nine different potato genotypes with two checks i.e. Desiree and Jumli Local were tested on Randomized Complete Block Design (RCBD). Each treatment was replicated four times. Compost was used at the rate of 20 tons per hectare. There was no use of chemical fertilizer. Well sprouted tubers of 25-50 g were planted with 60cm x 25cm spacing. The effects of different genotypes were recorded for both vegetative as well as yield parameters. Tested genotypes differed significantly for vegetative (emergence percentage at 30 days after planting & 45 days after planting, uniformity, ground coverage, plant height, number of main stems) as well as yield parameters (total number of tubers and tuber yield per ha). The highest tuber yield (20.9 t/ha) was harvested from CIP 392797.22. Result of consecutive years showed that potato genotype CIP 392797.22 is suitable for cultivation in high hills of Karnali province for food as well as nutritional security.

The trial was carried out to identify suitable potato genotypes for high hills of Karnali province of Nepal. The genotypes were received from International Potato Centre (CIP), Lima, Peru through National Potato Research Program (NPRP) and evaluated for two consecutive years 2017 and 2018 at Horticulture Research Station (HRS), Rajikot, Jumla, Nepal (2396 masl). Nine nutrient dense potato genotypes with two checks i.e. Desiree and Jumli Local in on-station trial were tested in Randomized Complete Block Design (RCBD) with three replications. Fertilizer was used at the rate of 100:100:60 kg NPK/ha and 20 t/ha compost. Well sprouted tubers of seed size (25-50 g) were planted at a spacing of 60cm x 25cm. The effects of different genotypes were recorded for both vegetative as well as yield parameters. There is a significant difference among tested genotypes for vegetative (emergence percentage at 30 days after planting & 45 days after planting, uniformity, ground coverage, plant height, number of main stems) as well as yield parameters (total number of tubers and tuber yield per ha). The highest tuber yield (46.93 t/ha) was recorded from genotype T 304351.109 followed by genotype T 304368.46 (41.46 t/ha) and genotype T 302498.7 (32.69 t/ha) among the nutrient dense potato genotypes. Similarly, late blight scoring was minimum (score 1) in all these three genotypes. The results of both years showed that potato genotypes T 304351.109, T 304368.46 and T 302498.7 are promising for cultivation in high hills of Karnali province to combat the malnutrition as well as ensure nutritional security.

“…But straw mulch contributed to the highest canopy cover, marketable tuber and yield indicating that straw mulch can be the best option to conserve soil moisture in water deficit areas. Shrestha et al (2020) have also mentioned the highest yield in straw mulch potato in comparison to non-mulch.…”

Variable rainfall and recurrent drought in spring season limit the potato production at Dailekh. To address this problem, a two-year (2019-2020) field experiment was conducted at HRS, Dailekh to investigate 12 potato genotypes (T-304347.6, T-393371.58, T-304350.1, T-304351.109, T-302498.7, T-304405.47, T-303381.3, T-396311.1, T-397029.1, T-304368.46, Desiree and Cardinal) along with different growing practices (Partial Irrigation (PI), rain-fed and straw mulch) for their growth, and yield traits. The experiment was laid out in split-plot design, where three different growing practices were allotted as main plot and 12 potato genotypes were placed as sub-plot treatment, and it was replicated three times. The combined analysis revealed that growing practices significantly affected the ground cover, plant height, stem number, marketable tuber number and weight, and yield. Potato genotypes showed the significant effect on all the plant and yield traits. Straw mulch produced 28.7% and 21.6% higher marketable tuber yield than PI and rain-fed potato, respectively. Genotypes T-304351.109 and T-397029.1 imparted 22.9% and 17.4% higher marketable tuber yield than Desiree, check variety, respectively. Therefore, growing of high yielding genotypes T-304351.109 and T-397029.1 along with straw mulch can be the best option to increase the potato productivity at rain-fed condition of Dailekh.
