In the future, the agricultural sector in many parts of the world is to produce more with less water. In this regard, this experimental study was carried out to evaluate the performance of AquaCrop model in simulating potato crop growth parameters under various water levels at Debre Birhan, Ethiopia (2019-2020. The simulated crop yield parameters were compared to experimental results for this purpose. The experiment was arranged in Randomized Complete Block Design, with four replications and under five water levels (115%, 100%, 85%, 70% and 55 %). The 100% water level was determined to be 377.2 mm of water depth in the growing season. The growth parameter and tuber yield were significant differences among the water levels at p < 0.05. The fresh potato tuber yield and water productivity ranges from 36.09 ton/ha to 43.13 ton/ha and 12.67 kg/m 3 to 10.5 kg/m 3 were obtained in 55% and 115% water levels respectively. The AquaCrop model performance in the canopy cover, dry aboveground and tuber biomass and soil water content of the potato crop. The statistical indicators; Nash-Sutcliffe efficiency (NSE), Normalized Root mean square error (NRMSE) index of agreement (d) and Coefficient of determination (R 2 ) showed very well to excellent efficiency, there value is in ranges on aboveground and tuber biomass ranges 0.78 to 0.99, 14.1 to 35.5, 0.96 to 0.99 and 0.96 to 0.98 was observed respectively. However, the results of soil water content before irrigation were found to be poor efficiency ranges -0.96 to 0.00, 10.2 to 10.7, 0.5 to 0.78 0.081 to 0.45 respectively in the above order. From the results of the study, we can conclude in two scenarios: First, in case of water scarce area, it may be more profitable for a farmer to maximize crop water productivity instead of maximizing the harvest per unit of land. The saved water can be used to irrigate extra units of land. Second, in case of no water scarce area, it may be more profitable to maximize the yield harvest than crop water productivity. Under the first scenario, farmers should adopt 70% of crop water requirement with a 10-days interval, which 16.65% saved water with 10.1% yield penalty over 100%. On the other hand, they should adopt 100% of crop water requirement within 10-days interval in the case of no water scarce area.

“…This may be due to that under wider spacing and whole tuber planting there was proper growth and development of the plant resulting in more yield of large-size tubers which ultimately increases the marketable yield, total yield as well and biological yield, while under closer spacing using cut tubers, there was higher plant population per unit area which increases the yield of all of the size tuber. The present finding also confirmed the results of Malik et al and Birhanu et al [15,11] who reported that the tuber yield per hectare was higher with whole tubers planting as compared to cut tubers under the same plant spacing.…”

“…The varietal difference in potato varieties concerning tuber yield, marketable yield as well and biological yield was also noticed by Yadav et al [16]. The present findings are following results reported by Abrha et al [17], Lal et al [18] and Birhanu et al [11]. The interaction effect between different plant spacings and potato varieties was found non-significant for tuber yield, marketable yield as well and biological yield.…”

Aim: Potato is one of the most prominent crops to eliminate hunger and poverty at the global level. It is one of the world's most widely consumed and important food crops, providing a significant portion of the world's dietary energy and nutrients. Methodology: The study was carried out at the research farm of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University- Hisar, India during the rabi season of the year 2021-22. The field experiment was conducted in a split-plot design with three potato varieties (Kufri Neelkanth, Kufri Bahar and Kufri Lima) and four different spacing (60×10 cm, 60×15 cm, 60×20 cm with cut tuber and 60×20 cm with whole tuber). Results: Among different spacings and varieties, spacing 60×20 cm with whole tuber and Kufri Neelkanth was found best for plant height at 60, 75 and 90 days after planting, number of leaves/hill, leaves weight/hill (g), stem weight/hill (g), weight of fresh foliage (kg/m2) and and total tuber yield (q/ha), biological yield (q/ha), respectively. Whereas, Kufri Bahar was found maximum for the number of stems/hill (7.22) and Kufri Lima for total marketable tuber yield (374.4 q/ha). Conclusion: The present study opens up new doors to the farmers and researchers for sustainable production of potatoes. The findings can be useful for farmers and researchers in developing effective strategies for improving the production of potato, which can have significant economic and nutritional benefits.
