Water shortage, excessive fertilization and improper variety selection have seriously restricted the sustainable development of potato in Northwest China. Two-year field experiments were conducted 2021 2022 to explore effects irrigation amount fertilizer application rate on growth, yield, nutrient uptake, quality, water, use efficiency, soil enzyme activity economic benefits different varieties. Three levels W1 (100% crop evapotranspiration (ETC)), W2 (80% ETC) W3 (60% ETC). rates F1 (240 kg N ha−1), F2 (180 ha−1) F3 (120 ha−1). locally grown cultivars V1 (Feiurita), V2 (Longshu 7), V3 (Qingshu 9). The results showed that amount, significantly influenced tuber commercial tubers, maximum weight, reduced sugar content, water productivity (WPI), partial (PFP), catalase (SCA), total income, net input-output ratio. chlorophyll photosynthetic rate, dry matter accumulation, starch vitamin C crude protein content increased with increase amount. With plant nitrogen (N), phosphorus (P), potassium (K) absorption, WPI, income first then tended stabilize or even decline. On average, WPI 19.3% (6.9%), 1.6% (1.6%), 8.8% (10.4%), 3.8% (10.5%) 21.1% (7.8%), 34.6% (14.9%) higher than those (2022), respectively. In two years, average PFP SCA treatment 13.1%, 14.5%, 16.4% 4.8% treatment, Among all treatments, T5 (W2F2V3) had highest P SCA, alkaline phosphatase (SPA), sucrase (SSA) lowest reducing content. Plant accumulation N, K was closely related yield a significant positive correlation SSA. Based comprehensive differential combination evaluation model, considering growth development, efficiency benefits, best treatment. After evaluation, optimal ranges 270–290 mm 167 ha−1 193 ha−1, present study provides basis for evaluating selecting better management practices effective varieties

Understanding the underlying reasons for farmers' AGPT adoption in context of resource environment tightening and agricultural carbon reduction has become crucial to promote agriculture sustainable development. This paper uses multiple ordered regression model probit test impact perceived value on their green production technologies (AGPT) by using first-hand data from 613 rice farmers Hunan, explores effect mechanism policy subsidies market incentives AGPT, investigates differences different stages. The results showed that, (1)farmers' is significantly affected value, which benefits promotes adoption, while risks opposite. But stages influenced value. soil testing fertilization technology (STFT) pre-production stage benefits; pest control (GPCT) mid-production both risks; straw return (SRT) post-production risks. (2) Farmers' can be encouraged subsidies, also have moderating decreasing negative influence behaviour. (3) Further analysis reveals that compensate limitations greatly regulate encourage them use technologies. Consequently, Government should actively publicize organize training technologies, provide diversified subsidy programmes And governments improve quality certification system price products, so as help adopting achieve an increase income.

With soil fertility loss reached a critical state in arid and semi-arid regions, farmers are constrained to use mineral fertilizers, which costly, non-eco-friendly less effective improving than organic fertilizers such as dewatered sewage sludge (SS) poultry manure (PM). In this regard, the current study aimed highlight through experiments positive effect of SS PM applications on durum wheat growth. It targeted demonstrate safe wise fertilization while assessing heavy metals both plant. The experiment was carried out two batches thirty-two pots, one for each treatment (SS PM), addition control with no fertilization. were applied separately three doses (D1 = 50 g, D2 100 D3 200 g DM fertilizer/pot). induced significant increase plant-available phosphorus, matter, nitrates, moisture electrical conductivity soil, where these improvements higher compared treatment. A accumulation proline associated an biomass that proportional fertilizer dose levels. Our findings revealed relative water content leaf area Correlations showed several relationships between parameters studied. most efficient properties plant components. Plant zinc concentration increased significantly amendments, however it decreased SS. These not copper fertilizers. Both improved growth control, thus practice is promising solution tackle low production drylands.

Under the carbon emission pattern of “peak and neutrality”, policy crop rotation fallow system (CRFS) is regarded as an important initiative to promote green, low-carbon, high-quality development agriculture. Focusing on balanced panel data from 30 provinces in China 2010 2021, this paper empirically examines impact CRFS agricultural emissions (ACEI) its internal mechanism using a multi-temporal difference-in-differences model. The benchmark regression results show that can significantly reduce ACEI, remain robust after validation by multiple methods. Mechanism able ACEI reducing factor mismatch promoting level services. Heterogeneity analysis arable land more conducive reduction intensity main grain producing areas, marketing high transfer plantation areas than production low transfer, animal husbandry areas. This study demonstrates effectiveness implementation, provides doctrinal basis for expanding scope recommendations relevant departments improve policy.

A sustainable approach to improving agrifood production: getting the balance right between organic soil amendments and chemical fertilizers

China Agricultural Economic Review, Год журнала: 2024, Номер 16(4), С. 646 - 663

Опубликована: Май 22, 2024

Purpose We analyzed the effects of different combinations organic soil amendments (OSAs) and chemical fertilizers on agrifood production, focusing banana yields in China, second-largest producer bananas globally. Design/methodology/approach computed these by dividing expenditures OSAs those called them OSA-CF ratios. First, we classified farmers based quintiles fertilizers. Then, studied association between ratios for each quintile. also considered an alternate specification which were grouped along ratio continuum. The first group comprised not using OSAs. Their was zero. Farmers applying low, medium, high constituted groups two, three, four; delineated tertiles, associations tertiles quintile analyzed. data used this study collected surveying 616 households three major banana-producing provinces (Guangdong, Hainan, Yunnan) China. Standard linear regressions two-stage predictor substitution method employed to complete analysis. Findings There variations obtained iifferent quintiles. For second quintiles, improved relative only fertilizers, a low associated with improvement 792 kg/mu yields. their counterparts quintile, same transition gain 534 kg/mu. fifth comprising spending 320 yuan/mu or more instead 401 decline Even so, group, no differences observed medium Practical implications Banana southern can improve combining if fertilizer are less than 66.67 yuan/mu. Those 68 300 maintain conjunction However, may they incorporate such that reaches 0.78 higher. Overall, while attenuating adverse environment. Policymakers should inform benefits accelerate sustainable agriculture through educational awareness programs. Originality/value apply as farmyard manure adjust remedy nutrition farm productivity. little is known about how affects This provided attempt explore cross-sectional farming households.

Balanced Fertilization Improves Crop Production and Soil Organic Carbon Sequestration in a Wheat–Maize Planting System in the North China Plain

Plants, Год журнала: 2025, Номер 14(6), С. 838 - 838

Опубликована: Март 7, 2025

Maintaining the long-term viability of a wheat–maize planting system, particularly synchronous improvement crop production and soil organic carbon (SOC) sequestration, is crucial for ensuring food security in North China Plain. A field experiment which was regarded as an integral fertilization unit carried out Shanxi Province, China, adopting split-plot design with different distribution ratios phosphorus (P) potassium (K) fertilizer between wheat maize seasons main plot (A) (a ratio 3:0, A1; 2:1, A2) application rates pure nitrogen (N) during entire growth period (B) (450 kg·ha−1, B1; 600 B2). Moreover, no used control (CK). The findings showed that A2B1 treatment led to highest response, average yield 7.75 t·ha−1 8.40 over last 9 years. SOC content (15.13 g·kg−1), storage (34.20 t·ha−1), sequestration (7.11 t·ha−1) were also observed under treatment. Both enhanced resulted from improvements cumulative (C) input, nutrients, stoichiometry It confirmed total N (TN), alkali-hydrolysable (AN), available P (AP), K (AK), C:K, N:K, N:P had positive effects on through labile components microbial necromass C.
