Wheat (Triticum aestivum L.) is a strategic agricultural crop that plays significant role in maintaining national food security and sustainable economic development. Increasing technical performance considering lowering costs, energy, environmental consequences are aims for wheat cultivation. For drylands, which cover approximately 41% of the world’s land surface, water stress has considerable negative impact on output. The current study aimed to assess aspects chemical fertilizer combination with compost dryland irrigated winter production systems through life cycle assessment (LCA). cradle-to-farm gate was considered as system boundary based one tone yield four strategies: D-C (dryland compost), D without I-C (irrigated I compost). Based results, highest lowest amounts were related strategies 12.2 6.7 ton ha−1, respectively. LCA result showed strategy comparison other had human health (49%), resources (59%), ecosystem quality (44%), climate change (43%). However, resulted adverse effect 6% health, 1% resources, 10% quality, 11% change. Utilizing areas could ensure higher crops addition alleviating indicators.

Effects of Humic Acid Added to Controlled-Release Fertilizer on Summer Maize Yield, Nitrogen Use Efficiency and Greenhouse Gas Emission

Agriculture, Journal Year: 2022, Volume and Issue: 12(4), P. 448 - 448

Published: March 23, 2022

Humic acid plays an important role in improving grain yield and reducing N losses. In order to explore the effects of humic added controlled-release fertilizer on summer maize yield, nitrogen use efficiency (NUE) characteristics greenhouse gas (GHG) emissions farmland soil, a two-year field experiment was set up. The treatments consisted two fertilizers: 3% (HACRF), (CRF) control (without fertilizer, N0). results demonstrate that NUE were significantly increased with addition fertilizer. Compared N0 CRF, by 99.1% 5.0%, respectively. contents soil ammonium–nitrogen (NH4+-N) nitrate–nitrogen (NO3−-N) HACRF higher during early growth stage but lower late grain-filling stage. interdependent rate 4.6–5.4% 7.2–11.6%, respectively, across years compared those CRF. Moreover, annual cumulative N2O decreased 29.0% Thus, global warming potential emission intensity 29.1% 32.59%, conclusion, adding can result uptake, improve reduce emissions, which have better environmental effects.

Response of greenhouse gases emissions and yields to irrigation and straw practices in wheat-maize cropping system

Agricultural Water Management, Journal Year: 2023, Volume and Issue: 282, P. 108281 - 108281

Published: March 20, 2023

Global water shortages and appropriate crop residues management are the major issues threatening sustainable development of agriculture, food security, environment. In this study, we conducted a one-year field experiment (in 2020–2021) to investigate annual yield, greenhouse gas (GHG) emissions, global warming potential (GWP) intensity (GHGI) in wheat-maize cropping system. Straw practices were kept main plot, including straw incorporation (SI) removal (SR). Irrigation allocated into sub-plots, surface drip irrigation (DI), sub-surface (SDI), partial rootzone (PRI), flood (FP). All treatments fertilized at level 210 kg N ha–1 for each season. The soil acted as net sink CH4 but source N2O emissions during growth period under all treatments. highest direct GHGs, GWP, GHGI found FP compared with other SI or SR. significantly increased yield (5.0%), emission (17.1%) ΔSOC (119.9%), decreased (19.4%) GWPd (19.6%), thus resulting GWP reduction 23.6% SR SDI. Additionally, best treatment minimizing negative environmental impacts was SDI, which reduced by 39.7% (P < 0.05), 43.0% 0.05) SI. We conclude that combined simultaneously mitigates GHG improves enhances C sequestration, making it suitable environment-friendly agricultural practice farming northern China.

A Review on Regulation of Irrigation Management on Wheat Physiology, Grain Yield, and Quality

Plants, Journal Year: 2023, Volume and Issue: 12(4), P. 692 - 692

Published: Feb. 4, 2023

Irrigation has been pivotal in sustaining wheat as a major food crop the world and is increasingly important an adaptation response to climate change. In context of agricultural production responding change, improved irrigation management plays significant role increasing water productivity (WP) maintaining sustainable development resources. Considering that cultivated arid semi-arid regions, which consumes high amounts water, developing with efficiency urgently required. Both scheduling methods intricately influence physiology, affect plant growth development, regulate grain yield quality. this frame, review aims provide critical analysis regulation mechanism on formation, key traits involved uptake utilization efficiency, we suggest series future perspectives could enhance wheat.

Straw return alleviates the greenhouse effect of paddy fields by increasing soil organic carbon sequestration under water-saving irrigation

Agricultural Water Management, Journal Year: 2023, Volume and Issue: 287, P. 108434 - 108434

Published: July 7, 2023

The comprehensive greenhouse effect depends on the trade-off between gas (GHG) emissions and soil organic carbon sequestration (SOCS) of paddy fields. Investigations straw return GHG SOCS under different water management regimes help clarify strategy to alleviate Therefore, a two-year field experiment was conducted investigate emissions, SOCS, rice yield. fields quantified by calculating emission intensity (GHGI) net (NGHGE). included four treatments: CI: controlled irrigation + removal; FI: flooded CI+SR: return; FI+SR: return. results showed that could increase yield regimes, average CI+SR were higher than FI+SR. Furthermore, compared with FI, FI+SR promoted increased global warming potential 36.37%, which significantly GHGI NGHGE 19.95% 22.63%, respectively. However, had no significant difference FI due water-saving mitigate CH4 caused decrease 22.02% 38.45%, combined is an effective
