Despite being an efficient nitrogen (N) management method, the effects of controlled-release urea combined with normal (CRUNU) on stem and root lodging yield in maize have been rarely reported. Therefore, we conducted a field trial for three years between 2020 2022 using two N fertilizer types (CRUNU (NU)) application levels (low: 135 kg ha–1; medium: 180 high: 225 ha–1) to evaluate their maize, factors involved. The results showed that, compared NU, CRUNU reduced rate under rates, all were lowest medium rate. decreased was mainly attributed improved synchronization supply demand, population traits (plant height, ear center gravity height), morphological (length mass density) basal second, third, fourth internodes (I2, I3, I4), increased mechanical properties (stem breaking strength rind penetration strength), greater resistance index (SLRI), enhanced chemical compositions (lignin its related synthetase activities, cellulose, hemicellulose) I2, I4, increases bending strength, average diameter, vertical root-pulling CRUNU. In addition, SLRI values different followed order of: I2 > I3 thereby indicating that played important roles resistance. Furthermore, grain by 1.27–44.83% rates. particular, there no significant difference high rates conclusion, at ha–1 may be superior method.

Using conservation tillage to grow crops that enhance soil quality, such as legumes, seems be one of the best solutions for sustainable agriculture. The field study was conducted identify effect cultivation technology and fertilization, via strip-tilling (reduced) vs. plowing (conventional), on availability uptake NPK Mg, well growth shoots roots yield green peas (Pisum sativum L.). research carried out in central Poland (53°05′16.8″ N, 19°06′14.4″ E) over two growing seasons 2016 2017. Our has shown spatial distribution macroelements is influenced by method. nutrient peas, their parameters, were also system. However, observed mainly first year study, which had less precipitation higher temperatures. In general, our strip-till a positive impact plants, contributing longer biomass accumulation, especially part season. 2016, with rainfall, under produced more pods per plant than (by 13.8%). 2017, precipitation, an increase compared 9.1%), but this difference not statistically significant. To sum up, strip-tillage have macroelements, can recommended production crop.

In plant horticulture, furrow fertilizing is a common method to promote nutrient absorption and effectively avoid fertilizer waste. Considering the high resistance caused by soil compaction in southern orchards, an energy-saving ditching device was proposed. A standard blade with self-excited vibration designed, operated sandy clay tillage depth of 30cm. To conduct experiments, simulation model interaction between mechanism established coupling ADAMS EDEM software. begin with, first set up, taking into account its motion morphological characteristics. Then, MBD-DEM employed investigate effect particles blade. Afterwards, time-domain frequency-domain characteristics signals during process were analyzed using fast fourier transform (FFT) method, energy distribution extracted power spectral density (PSD). The experimental results revealed that vibrations has reciprocating displacement Dx direction torsional displacements θy θz directions operation, verifying correctness effectiveness reduction. Also, load bench test conducted, demonstrated device, compared achieved reduction up 12.3%. reasonable parameters spring stiffness, damping, quality can achieve satisfied performance relatively low torque consumption at appropriate speed.

During the later reproductive period of rice growth, chlorophyll in leaves degraded, accompanied by nitrogen (N) transportation from to panicle, resulting a change leaf color green yellow. This study aimed investigate effects exogenous N supply on color-changing, accumulation, transportation, and loss indica-japonica hybrid during grain-filling stage. Two cultivars, Chunyou 167 (CY167) 927 (CY927), which exhibited significant differences color-changing stage, were selected as materials for field experiment hydroponic with low, medium, high treatments (LN, MN, HN). The dynamic changes SPAD value heading maturity measured fitted quadratic function extract parameters; labeled 15N was used source after trace panicle remobilization vegetative organ N. results showed that 67.37–72.38% transported organs, transport efficiency upper three > lower stem, about 3.1–35.0% lost via volatilization. concentration harvest index, dry matter/grain production efficiency, reuse closely related parameters. In MN HN treatment, negatively correlated onset time (T0) final index (CIf), but positively rate (Rmean). Increasing increased T0 CIf, decreased Rmean, transport/reuse efficiency. Compared cultivar CY167 normal “stay-green” CY927 had higher T0, less volatilization loss, while conclusion, affects influencing

Improved fertilizer management, with a combination of organic and inorganic inputs, has the potential to enhance rice yield while maintaining soil health. However, studies on effects broadcast prilled urea (PU) deep placement (UDP) applied in inputs (poultry litter [PL] vermicompost [VC]), as integrated plant nutrition systems (IPNSs), yields nitrogen use efficiency (NUE) under alternate wetting drying (AWD) irrigation are limited. We conducted field experiments during dry wet seasons 2018, 2019, 2020 investigate treatments, including control (no nitrogen), UDP, PU, IPNSs (PU + VC, PU PL, UDP PL) NUE two regimes - AWD continuous flooding (CF). The results revealed that treatment regime had significant (p < 0.05) interaction agronomic N (AEN) season. significantly boosted yield, total matter (TDM), compared both seasons. Similarly, IPNS PL TDM, comparison PU. Under irrigation, alone produced higher than other similar CF irrigation. During season, increased AEN when conditions, but demonstrated equivalent CF. This research implies using or an could be good way boost crop productivity also fertility.

Hetao Irrigation District (HID) is one of the main regions for maize and sunflower production in North China. However, water resource shortages soil salinization greatly limit production. The surface irrigation method HID; however, now, plastic mulching drip area increasing to reduce enhance crop yield. In this study, water, salt, nitrogen contents at 0–100 cm layer under non-mulching conditions with irrigation—fertilizer broadcast practice fertigation were investigated elongation maturation stages 2021 2022 seasons. results show that methods influenced salt ionic (NO3− NH4+) distributions and, ultimately, Mulching reduced content 0–20 by a mean 35.7% 18.6% condition. NO3− system was approximately 8 times higher than out mulching. However condition, 8–10 lower distributed uniformly each deeper 40 depth, indicating minor effects NH4+ decreased as depth increased layer, insignificant influence practice. As result, yield drip-mulching condition 11% (10.6~11.4%) surface-mulching two Given currently primary (HID), we have proposed three approaches aimed enhancing through improvement levels practices.

Despite growing interest in controlled-release N fertilizers (CRNFs) because of their potential for enhancing nitrogen use efficiency (NUE) and economic returns, comprehensive impact on machine-transplanted rice remains to be understudied. To address this gap, here, we present a two-year field experiment that assessed the CRNF using mechanical deep placement fertilization (DPF) cultivation. The study involved three types (bulk blending fertilizer (BBF), polymer-coated urea (PCU), sulfur-coated (SCU)) two methods (DPF broadcast application), with high-yield split as control (CK). results showed DPF, especially SCU, greatly enhanced soil NH4+-N concentrations, NUE, yield, benefits compared application. BBF consistently exhibited superior NUE notable benefits, regardless application method used. Conversely, single-time PCU was less favorable growth. In conclusion, optimal DPF combined SCU is recommended. However, if not feasible only broadcasting possible cultivation, emerges ideal choice both high significant returns. This research offers insights improved management rice, effectively optimizing profitability.
