Effects of water-nitrogen interaction on some physiological characteristics and grain yield in hybrid rice during grain filling by SUN Yong-jian, SUN Yuan-yuan, LIU Kai, ZHANG Rong-ping, MA Jun

“…Super hybrid rice Gangyou 527 was used to investigate the effects of three irrigation regimes (submerged irrigation, dry cultivation, the treatment W2 that damp irrigation before booting stage, shallow irrigation at booting stage, wetting-drying alternation irrigation from heading stage to mature stage) and different amounts of N application on photosynthetic rate (Pn), activities of nitrate reductase (NR), glutamine synthetase (GS), glutamate synthase (GOGAT), endopeptidase (EP) in flag leaves, bleeding intensity (BIS) in basal internodes and grain yield during grain filling, and studied correlations among the photosynthesis, nitrogen metabolism enzyme activity and root vigor at this stage. …”

Multi-source Data-driven Analysis of Deformation and Influencing Factors for Expansive Soil Canal Slopes by ZHANG Yuhan, HU Jiang, LI Xing

“…ObjectiveDeep excavated expansive soil canal slopes frequently exhibit significant deformation and poor stability due to the combined effects of excavation unloading, wet-dry cycles, and groundwater level fluctuations. …”

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). …”

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.…”
