    Water and nitrogen regulation strategy for wolfberry farmland based on nitrogen balance in the Yellow River irrigation districts of Gansu Province, China by Minhua Yin, Rongrong Tian, Yi Ling, Yuqing Yang, Yanlin Ma, Yanxia Kang, Guangping Qi, Jinghai Wang

    Published 2025-02-01
    “…Agricultural production frequently encounters challenges, including soil nitrogen pollution and imbalances resulting from improper irrigation and fertilization practices. This study focuses on wolfberry farmland, analyzing the effects of four irrigation levels [full irrigation (W0, 75%−85% θf), mild water deficit (W1, 65%−75% θf), moderate water deficit (W2, 55%−65% θf), and severe water deficit (W3, 45%−55% θf)] and four nitrogen application levels [no nitrogen application (N0, 0 kg·ha−1), low nitrogen application (N1, 150 kg·ha−1), medium nitrogen application (N2, 300 kg·ha−1), and high nitrogen application (N3, 450 kg·ha−1)] on nitrogen uptake by wolfberry plants, soil nitrogen loss, plant-soil nitrogen balance, and nitrogen use efficiency. …”

    Snap Bean (Phaseolus vulgaris) Response to Deficit Irrigation and Nitrogen Fertilizer and Relationships between Yield, Yield Component, and Protein Content by Melaku Fisseha Teferi, Bizuayehu Tesfaye, Abraham Woldemichael, Adugna Debella

    Published 2022-01-01
    “…The treatments were deficit irrigation with three levels (50, 75, and 100% ETc) and application of nitrogen with four levels (0, 46, 92, and 138 kg·N·ha−1), which were set up as split-plot arrangement, with irrigation being as the main plot and nitrogen levels as subplot, replicated thrice. …”
