Jujube is a perennial tree primarily planted for edible fruits. The crop is famous in Asia but relatively unknown to the United States. Prospects of jujubes as an alternative future crop in New Mexico are increasing but the lack of proper extension and promotion caused many farmers to be unknown with the crop. Also, the lack of saplings and field-based research information have restricted its cultivation in New Mexico. Thus, we performed field experiments (2019 and 2020) to investigate water and fertilizer influence on jujube growth performance. For this study, we applied three levels of water (2: low, 8: medium, and 16 L: high), and fertilizers (35: low, 70: medium, and 140 g: high) to jujube plants. Control treatments did not receive any amount of water and fertilizer. Variables such as increment in plant height, stem diameter, number of leaves, leaf sizes, and chlorophyll contents were recorded. The 16 L water and 70 g fertilizer increased plant height and diameter by 60.1 cm and 5.23 mm in 2019, and 67.81 cm and 6.18 mm in 2020, respectively. Leaf length and width under W3F2 were 5.68 cm and 2.80 mm in 2019, and 5.85 cm and 2.98 mm in 2020, respectively. Similar trend was found in terms of leaf number. Leaf chlorophyll concentration was also positively influenced by water-fertilizer application. Based on the findings of our research project, we recommend 16 L water and 70 g NPK fertilizers per plant in young jujube orchards in order to maximize growth. This information guides farmers to adopt better water fertilizer management strategies in the orchards to enhance crop performance. These findings might encourage farmers to consider jujubes as an alternative crop in New Mexico.
