The study ran for 14 consecutive years (2011–12 to 2024–25) at the Regional Agricultural Research Station, Anakapalle, using a randomized block design with two farming systems: organic farming (OF) and conventional farming (CF). The investigation assessed cane yield, yield attributes, juice quality, soil properties, microbial populations, and economic returns. Two-way ANOVA showed that treatment effects had no significant impact on cane yield and yield attributes, juice quality parameters, economic elements, soil physicochemical, nutrient, and microbe parameters, except phosphate-solubilizing bacteria (PSB), indicating comparable performance of the two farming systems. Organic farming recorded numerically higher mean values for cane yield (72.38 t ha⁻¹), sugar yield (9.64 t ha⁻¹), sucrose (18.75%), commercial cane sugar (13.05%), soil organic carbon (0.71%), and net returns (₹180,527 ha⁻¹), whereas conventional farming maintained higher available soil nitrogen, phosphorus, and potassium. Soil health indicators were significantly improved under organic farming, evidenced by higher soil organic carbon (0.71%), lower electrical conductivity (0.20 dS m⁻¹), and stable pH, although treatment differences were not statistically significant. Among the microbial parameters, the population of phosphate-solubilizing bacteria (PSB) was the only trait with a significant treatment effect. Organic farming had much higher counts at 13.81 × 10³ cfu g⁻¹ compared to conventional farming at 6.67 × 10³ cfu g⁻¹, while the differences in Azospirillum and Azotobacter populations were not significant. Economic analysis showed similar profitability between the two farming systems. Organic farming had slightly higher net returns (₹180,527 ha⁻¹) and a benefit–cost ratio (0.88), but these differences were not statistically significant. This study was conducted at a single location with a single sugarcane variety, so the findings may not generalize to all agro-climatic conditions. More validation is necessary before applying the results broadly. Future research should test multiple sugarcane varieties across different agro-ecological regions with long-term organic management.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"28 6","pages":"1971 - 1984"},"PeriodicalIF":1.9,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hybrid seed production in sugarbeet is a complex, multi-stage process that begins with breeding parental lines and culminates in commercial hybrid seed production through crossing male-sterile single crosses with pollinators. In Iran, commercial sugarbeet hybrid seeds are produced almost exclusively in the Ardabil agricultural region. Given the substantial economic value of both basic and commercial sugarbeet seeds, this study aimed to identify yield-limiting factors in seed production fields. We collected 224 variables—including soil properties, field management practices, phenological characteristics, weather data, and seed yield—from 90 farms (98.8 hectares) during the 2022 growing season (March–September). Quantile regression analysis at τ = 0.9 identified five major yield-limiting factors: (1) number of days with relative humidity &lt; 20% during the reproductive period, (2) number of days with relative humidity &lt; 30% during vegetative growth, (3) field cover percentage, (4) sunshine duration during flowering, and (5) number of irrigations during vegetative growth. Collectively, these factors, identified during the 2022 production season, accounted for approximately 40% of the observed yield gap. Random forest analysis independently validated these five factors, with all ranking in the top 15 most important variables and collectively explaining 37.4% of model importance. Optimizing irrigation schedules during vegetative growth, combined with favorable humidity and sunshine conditions during flowering could substantially narrow the yield gap in sugarbeet seed production fields.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"28 6","pages":"1959 - 1970"},"PeriodicalIF":1.9,"publicationDate":"2026-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the spatial distribution and evolutionary trajectory were delineated, the decoupling relationship between the sugarcane net carbon sink and output value was analyzed, and precise predictions of the net carbon sink were conducted in Chinese sugarcane industry. Results showed that, from 2012 to 2023, the total net carbon sink displayed a fluctuating yet gradually declining trend, with an average value of 13.5906 million tons. Besides, the spatial configuration of the total net carbon sink was primarily characterized by a “northwest–southeast” distribution pattern. Regarding the projected total net carbon sink for 2024 and 2025, it is estimated at 13.7527 and 13.2282 million tons, respectively, with corresponding theoretical values of 2.063 and 1.984 billion US dollars. It is thus recommended that the planting scale in primary producing regions be maintained, the “northwest–southeast” spatial structure be reinforced, and the recovery and development of Hainan’s sugarcane sector be promoted. Rational monetization of the sugarcane net carbon sink is also suggested to elevate the overall industrial output value and benefits.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"28 5","pages":"1760 - 1772"},"PeriodicalIF":1.9,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, text mining techniques and the policy modeling consistency (PMC) index model were used to examine the development path and policy tools of Chinese sugarcane industry policies, and to quantitatively evaluate selected policy samples. The results show that sugarcane industry policies have maintained a clear objective orientation in China, while their functional roles and strategic positioning have been continuously adjusted and upgraded. This process reflects a development path characterized by “exploration and development—adjustment and reform—quality improvement and efficiency enhancement.” Five major policy tools have been used: excellent varieties and effective techniques, mechanization, research and development innovation, financial subsidies, and organizational coordination. The frequency ranking is: organizational coordination &gt; excellent varieties and effective techniques &gt; mechanization &gt; research and development innovation &gt; financial subsidies. Among these tools, organizational coordination is the most influential, and the coordination among different policy tools has become increasingly apparent with the development of the sugarcane industry. In terms of implementation effectiveness, the average performance of the policy samples reaches an excellent level, indicating strong relevance and practical feasibility. However, regional disparities remain evident, with PMC index rankings of Guangxi (5.6833) &gt; Yunnan (5.5833) &gt; Guangdong (3.8833) &gt; Hainan (3.1166). Therefore, during the stages of “exploration and development—adjustment and reform,” the Chinese government has actively performed the role of a “proactive government” by optimizing the industrial structure and promoting the high-quality development of the sugarcane industry. In the future, Chinese sugarcane industry should gradually move from policy-driven support to competition-oriented mechanisms, and from government-led guidance to function-based differentiation, thereby improving industrial competitiveness and better safeguarding the security of the sugarcane industry.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"28 6","pages":"1946 - 1958"},"PeriodicalIF":1.9,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The soil column leaching experiment revealed that imidacloprid exhibited moderate mobility, redistributing up to 15–20 cm depth depending on soil type and water flow conditions, while no breakthrough into the leachate was observed. However, fipronil showed strong sorption-driven immobility, with over 85–90% of residues retained within top 0–5 cm soil layer across all treatments. The co-presence of fipronil caused only minor competitive effects on imidacloprid mobility, suggesting limited interaction at the test concentrations. Soil texture and organic carbon content played a key role in restricting the pesticide movement. The present findings indicate a low immediate risk of groundwater contamination, while highlighting the importance of evaluating pesticide mixture behaviour for more precise environmental risk assessment.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"28 6","pages":"1935 - 1945"},"PeriodicalIF":1.9,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a structural element of cell walls and membranes, Ca²⁺ is also an essential secondary messenger in numerous physiological and signalling processes. This review provides a comprehensive overview of Ca²⁺ dynamics in sugar crops, focusing on its concentration, uptake, and transport mechanisms. Its physiological function ranges from membrane stability to cell extension and enzymatic control, all of which are essential under normal and stress conditions. Ca²⁺ deficiency in sugar crops results in apparent symptoms, such as leaf tip necrosis, impaired root growth, and reduced sugar accumulation, ultimately reducing crop yield and quality. New developments in Ca²⁺ sensor proteins, including calmodulins, calcineurin B-like proteins (CBLs), and CBL-interacting protein kinases (CIPKs), underscore their significance in transducing Ca²⁺ signals under abiotic stress conditions, including drought and salinity. Furthermore, the exogenous application of Ca²⁺—through soil, foliar, or fertigation methods—has been documented to alleviate stress-induced damage by promoting antioxidative defence, osmotic balance, and nutrient uptake. The facilitatory function of Ca²⁺ in the regulation of stress-responsive genes and enhancing tolerance mechanisms is gaining prominence as a sustainable strategy in sugar crop management. This review seeks to integrate existing research on the physiological, molecular, and agronomic importance of Ca²⁺ with an emphasis on its potential as a strategic tool in promoting abiotic stress resilience in sugar crops under conditions of climate change.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"28 5","pages":"1447 - 1457"},"PeriodicalIF":1.9,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis adopted an intersectional lens to examine structural exclusion across social, cognitive, and economic dimensions. Findings demonstrate that the implicit grower profile is not a historical relic but a persistent structural pattern in contemporary innovation systems. Most reviewed centers show an absence of extension programs specifically designed for women, elderly growers, or resource-constrained smallholders. While industry standards such as the Bonsucro Production Standard establish gender thresholds for management, these benchmarks do not extend to the intersectional heterogeneity of the producer base. Consequently, low technology adoption is identified not as an individual failure but as a rational response to an institutional choice architecture misaligned with real-world users.
