Irrigation methods and nitrogen-form interactions regulate starch-metabolising enzyme activity to improve rice yield and quality by Haojing Li, Hairun Li, Danke Zhang, Mengmeng Jiang, Jing Cao, Guowei Xu

“…A soil-growth experiment was conducted using a high-lodging-resistance rice cultivar under three irrigation methods, namely, submerged irrigation (0 kPa), alternate wetting and moderate drying (-20 kPa), and alternate wetting and severe drying (-40 kPa), as well as three nitrogen forms, namely, ammonium nitrogen (NH4+-N), mixed ammonium + nitrate (50:50), hereafter denoted as 50:50, and nitrate nitrogen (NO3--N). …”

Quantification of Subsurface Hydrological Connectivity Using Wavelet Coherence Analysis by REN Ruijie, Fan Bihang, ZHANG Yaling, WANG Erqing, YANG Ruxin, HAN Xiaole, LIU Jintao, GUO Li

“…This is likely related to rainfall event dynamics and soil structure: soil moisture in the study area exhibits a wetting-drying cycle driven by rainfall events, with shallower soils responding more sensitively to rainfall; soils with high rock fragment content facilitate the formation of vertical connectivity. 2)Pronounced aspect differentiation (shaded vs. sunny slope) was observed in lateral subsurface process connectivity. …”

Yield and water productivity of rice as influenced by crop establishment and irrigation methods under temperate environment by Tasneem Mubarak, Intikhab Aalum Jehangir, Ashaq Hussain, Eajaz Ahmad Dar, Zahoor Ahmad Shah, Aabid H. Lone, Mohd Salim Mir, Salah El-Hendawy, Mohamed A. Mattar, Ali Salem

“…Overall, the study indicates that adopting DSR with either the saturation or alternate wetting and drying irrigation methods can lead to higher yields, improved economic returns, and increased water productivity in temperate environments, positioning it as a more sustainable and efficient alternative to transplanted rice cultivation.…”
