“…Alfalfa is mainly located at mid-to high latitudes and frigid regions in China [5,24]. Winter hardiness is one of the major characteristics affecting alfalfa growth and productivity [25,26]. The results of this research showed that among the alfalfa cultivars selected for the field experiment, the ASI values of the indigenous cultivars are lower than those of the introduced American cultivars.…”

Integration of perennial grass species into the current food production systems, especially in the agropastoral regions worldwide, may produce multiple benefits including, among others, a more stable productivity and a smaller eco-environmental footprint. However, one of the fundamental challenges facing the large-scale adoption of such grass species is their ability to withstand the vagaries of winter in these regions. Here, we present a comprehensive evaluation of the winter hardiness of 50 indigenous Chinese cultivars of alfalfa, a high-quality leguminous perennial grass, in comparison with six introduced U.S. cultivars in a multi-site field experiment in northern China. Our results reveal that indigenous cultivars have stronger winter hardiness than introduced cultivars. Cultivars native in the north performed better than southern cultivars, suggesting that suitability evaluation is an unavoidable step proceeding any regional implementations. Our results also show that the metric we used to assess alfalfa’s winter hardiness, the average score index (ASI), produced more consistent results than another more-widely used metric of winter survival rate (WSR). These findings offer a systematic field evidence that supports regional cropping system adjustment and production system betterment to ensure food security under climate change in the region and beyond.

“…This study has shown that the growth and development of alfalfa cultivars depended on the weather conditions, environmental factors and genetic differences between cultivars. Winter hardiness is one of the major characteristics affecting alfalfa growth and productivity in long term period [29,30]. In all experimental year, the weather conditions In 2019, the cultivar Magnat was the least damaged by the DM at the first cut.…”

Alfalfa exhibits high adaptability to a range of environmental conditions. The aim of this study was to evaluate the agro-biological traits of alfalfa and select its most promising cultivars under different contrasting vegetation seasons. The field experiment was carried out at the Institute of Agriculture of Lithuanian Research Centre for Agriculture and Forestry. In 2016 and 2018, eleven alfalfa cultivars of different origin were established in the Endocalcari Epigleyic Cambisol. In the seasons of 2017–2018 and 2019–2020, the agro-biological traits of alfalfa cultivars were evaluated during winter; at the height of spring regrowth; before flowering at the three cuts; and during the fresh and dry matter yields; we also examined the development of diseases at the three cuts. The cultivar Birutė from Lithuania was distinguished by its wintering, its plant height at spring regrowth, its height before flowering, and its fresh and dry matter yields. The cultivar Timbale from France was distinguished by its wintering, spring regrowth, and its height before flowering. The cultivar Magnat from Romania was distinguished by its height before flowering and the fact that it was less damaged by downy mildew. The cultivars Jõgeva 118, Juurlu, and Karlu from Estonia were distinguished by their wintering and the fact that they were less damaged by diseases. The cultivar Eugenia from Italy was distinguished by the fresh and dry matter yields and the height before flowering.

“…The estimated dry bean seasonal ETa averaged 512.8 ± 46, 484.9 ± 39, 505.6 ± 67, 507.4 ± 59, and 520.0 ± 60 mm for the growing seasons of 2016, 2017, 2018, 2019, and 2020, respectively. Alfalfa is a perennial high-value forage crop usually planted in fall or spring; however, fall planting yields higher than the spring planting during the first production year [65][66][67]. For this research, the planting year data were removed from the dataset to better help plan water management throughout the year of well-established alfalfa fields regardless of the second, third, fourth, or fifth year after planting.…”

“…For this research, the planting year data were removed from the dataset to better help plan water management throughout the year of well-established alfalfa fields regardless of the second, third, fourth, or fifth year after planting. The monthly alfalfa ETa varied with years and rapidly increased from January to May and slightly decreased in June, July, August, and September, corresponding to the first, second, third, and fourth cut, respectively, in the study area [12,43,67] (Figure 8). Alfalfa ETa decreased from September to December when air temperature drastically decreases in winter, and reduced alfalfa growth plants go into the dormancy stage from November to February, with intrinsic variation due to the fall dormancy rating for the planted alfalfa varieties.…”

Crop evapotranspiration (ETa) is the main source of water loss in farms and watersheds, and with its effects felt at a regional scale, it calls for irrigation professionals and water resource managers to accurately assess water requirements to meet crop water use. On a multi-crop commercial farm, different factors affect cropland allocation, among which crop evapotranspiration is one of the most important factors regarding the seasonally or annually available water resources for irrigation in combination with the in-season effective precipitation. The objective of the present study was to estimate crop evapotranspiration for four major crops grown on the Navajo Agricultural Products Industry (NAPI) farm for the 2016–2010 period to help crop management in crop plant allocation based on the different objectives of the NAPI. The monthly and seasonal satellite-based ETa of maize, potatoes, dry beans, and alfalfa were retrieved and compared using the analysis of variance and the least significant difference (LSD) at 5% of significance. Our results showed the highly significant effects of year, months, and crops. The year 2020 obtained the highest crop ETa, and July had the most evapotranspiration demand, followed by August, June, September, and May, and the pool of April, March, February, January, December, and November registered the lowest crop ETa. Maize monthly ETa varied from 17.5 to 201.7 mm with an average seasonal ETa of 703.8 mm. The monthly ETa of potatoes varied from 9.8 to 207.5 mm, and their seasonal ETa averaged 600.9 mm. The dry bean monthly ETa varied from 10.4 to 178.4 mm, and the seasonal ETa averaged 506.2 mm. The alfalfa annual ETa was the highest at 1015.4 mm, as it is a perennial crop. The alfalfa monthly ETa varied from 8.2 to 202.1 mm. The highest monthly crop ETa was obtained in July for all four crops. The results of this study are very critical for cropland allocation and irrigation management under limited available water across a large commercial farm with multiple crops and objectives.
