Farmland mulching and optimized irrigation increase water productivity and seed yield by regulating functional parameters of soybean (Glycine max L.) leaves

Agricultural Water Management, Journal Year: 2024, Volume and Issue: 298, P. 108875 - 108875

Published: May 16, 2024

In both arid and semi-arid regions, adopting field mulching can effectively optimize soil moisture distribution, enhance crop yields, improve water productivity. While acknowledging its advantages, seems insufficient for maintaining high productivity due to the increasing frequency of extreme weather. Furthermore, drought often coincides with critical growth stages, necessitating implementation agricultural irrigation ensure normal growth. Accordingly, we conducted a three-year experiment from 2021 2023 including three typical methods (no mulching, NM; straw SM; plastic film FM) supplementary strategies (irrigated at branching stage (V4), W1; irrigated pod-filling (R2), W2; V4 R2 stage, W3). Throughout entire period, monitored conditions each treatment, measured leaf physiological parameters crucial assessed soybean yields (WP). Our findings indicated that, relative SM NM, FM maintains optimal balance, augments chlorophyll content, enhances photosynthesis, resulting in an average yield increase 17.0% 38.3% over growing seasons. Additionally, also significantly affects seed soybean. FMW2 achieved higher (4307.5 kg ha−1, 3-year averaged), had insignificant difference highest 4568.6 than other treatments. Similarly, area index, net photosynthetic rate (Pn) transpiration (Tr) presented between FMW3, while WUEleaf (Pn/Tr) obviously that FMW3. As result, WP 12.2 ha−1 mm−1 seasons, compared treatments, ranges 5.6% 46.7%. summary, treatment optimized distribution meet demands soybeans during reproductive achieving beneficial balance production by regulating functional parameters. Future research will explore more specific scheduling techniques (e.g., precision irrigation, deficit sensor-based management systems) integrating innovative materials biodegradable films) further resilience under evolving climatic conditions.

No-tillage with straw mulching increased maize yield and nitrogen fertilizer recovery rate in northeast China

Agricultural Water Management, Journal Year: 2024, Volume and Issue: 292, P. 108687 - 108687

Long-term intensive tillage has led to soil environment degradation, reduced fertility, difficulty in increasing maize yield, and low nitrogen (N) use efficiency the Mollisol region of northeast China. In order raise yield improve hydrothermal environment, we conducted field experiments investigate effects different practices straw returning on N fertilizer recovery loss, aiming increase both rate. Four treatments were established: flat no-tillage with full mulching (NM), ridge (RM), rotary incorporation (RR), conventional without (CK) as control treatment. The two-year results indicate that increased 15N rate, accompanied by improvements water content (SWC) regulation temperature changes, compared CK Specifically, total rate RM was significantly 15.23% 23.46%, while losses notably 14.99% 25.12%, respectively, NM RR treatments. Additionally, 3.10% 2021 1.97% 2022 (P < 0.05), it 2.06% 0.91% > 0.05). mean SWC 0–100-cm layer 7.99% 5.74% 8.09%, 5.50% during growth seasons. At 60–80 days after sowing (DAS), when air higher, lower than treatments, 0.46 ℃ 0.54 0.31 0.70 2022. However, decreased at 100–140 DAS, 0.69 0.81 0.73 0.94 Our study indicates treatment is most suitable practice method

Drip Fertigation with Moderate Nitrogen Topdressing Rate Achieves High Nitrogen and Water Use Efficiencies for Irrigated Wheat

Agronomy, Journal Year: 2025, Volume and Issue: 15(2), P. 259 - 259

Published: Jan. 21, 2025

Drip fertigation (DF) can improve yield, water use efficiency (WUE), and nitrogen (NUE, grain production per unit of the sum soil inherent mineral N fertilizer N), as well reduce risk environmental pollution compared with flood irrigation broadcast (FB). Previously, we showed that DF enhanced response yield to topdressing rate (NTR), but underlying mechanisms associated supply, root architecture, uptake remain unclear. We conducted a field experiment by testing six treatments (no applied, NTRs 0, 40, 80, 120, 160 kg ha−1, denoted N0, T0, T40, T80, T120, T160, respectively) under FB from 2021 2023. Compared FB, NUE WUE were 4.8–4.9% 10.0–10.5% higher DF. The was due an improvement in (6.1–7.7%) resulting aboveground (AGN). greater AGN attributed availability at depth 0–40 cm. decreased residual NO3−-N 40–200 cm increased In addition, combined T80 achieved high length density, surface dry weight density improved WUE. efficient utilization N, NTR threshold 61.75–119.50 which conditions similar those experimental site. Our results provide reference for high-efficiency usage irrigated winter wheat North China.
