The results revealed a gradual but consistent diversification of India’s dairy exports, particularly in East Asia and the Gulf countries, whereas exports to Central and South Asia remained highly concentrated. Econometric evidence suggested that institutional and regional factors played a more decisive role than market size and price effects. In particular, Regional Trade Agreements significantly reduced export concentration, with AIPW estimates indicating a 21.1 per cent improvement in diversification for partner countries.

In an electrostatic pollinator, configurations of high-voltage electrostatic electrode significantly impact the electric field strength and its distribution pattern, initiating pollen detachment process. This study investigates the effect of electrode geometries, namely, ring, spherical, cylindrical and conical type electrode, on electric field generation and distribution by finite element analysis using ANSYS Maxwell 2024 R1.1. This paper also evaluates the effect of high voltage applied on the electrode and pollen-electrode distance on electric field. Simulation results demonstrate the intensification of electric field strength with increase in electrode voltage, which is highly dependent on the shape and arrangement of electrode. Ring and cylindrical electrodes generate uniform electric field, with maximum intensity of 1.01 × 10<sup>6</sup> V·m<sup>−1</sup>and 5.33 × 10<sup>6</sup> V·m<sup>−1</sup> respectively. But in contrast conical electrodes produce localized high-intensity regions (E<sub>max</sub> 1.07 × 10<sup>6</sup> V·m<sup>−1</sup>), which may induce corona discharge. Besides, the spherical electrode produces symmetrically distributed electric field due to uniform surface charge distribution. Conversely, reduction in the pollen-electrode distance resulted in a stronger electric field. Ring electrode offers relatively uniform and high electric fields suitable for broad-area electrostatic pollination, while spherical electrode provide lower, more localized fields advantageous for targeted applications. The findings highlights the pivotal role of electrode topology in enhancing electrostatic applications such as artificial pollination, controlled droplet delivery and particle collection, with broader implications for environmental sustainability and global food security.</p>\u0000 </div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"15 3","pages":"1953 - 1968"},"PeriodicalIF":1.5,"publicationDate":"2026-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148903289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demand for aquatic foods is on the rise and is expected to grow more. This growth is directly linked to the increasing fish waste across the globe. Notably, fish skins, comprising 3–10% of fish body weight, are often discarded and contribute to this fish waste. ICAR-CIFE has developed a Novel Fish Skin Leather using discarded fish skin waste of snakehead. This leather was tested and met quality standards set by the Bureau of Indian Standards for leather products, including watch straps and bookbinders. The objective of this study was to evaluate consumer perceptions of this leather among various stakeholder groups, which included leather professionals, textile designers, leather crafts persons, leather consumers, and fisheries professionals. Adopting the standard protocols, the sensory evaluation was assessed for visual, olfactory, auditory, and tactile attributes. Analysis of Variance (ANOVA) was performed to determine whether there were statistically significant differences in means among the groups. All sensory attributes had an overall score of 0.89 ± 0.10, which is a very high acceptance score. The tactile attributes had a very high acceptance score (0.92 ± 0.10), followed by olfactory (0.89 ± 0.08), visual (0.87 ± 0.14), and auditory (0.86 ± 0.10) attributes. ANOVA revealed no significant difference existed between the consumer groups (<i>p</i> > 0.05). The leather developed from discarded fish skins holds significant promise as a sustainable alternative in the leather and textile industries. The positive consumer perceptions underscore its potential to contribute to the circular economy, achieve sustainable development goals, and reduce fish waste.

This review explored the role of indigenous farming practices in combating food insecurity. We explored empirical data involving indigenous land management in agriculture, soil fertilisation, planting methods, and control of pests and diseases in southern Africa. Various databases were consulted using search engines, covering data from 2010 till 2023. The literature search yielded 15 eligible studies that covered countries in southern Africa except Mozambique and Eswatini. The four land management practices identified were fallowing, shifting cultivation, zero tillage, and minimum tillage. Four materials, namely farmyard/manure, grass/crop residue, ash, and mound from termites were used by indigenous farmers in southern Africa to increase soil fertility. Five crop production cultural practices including relay planting, intercropping, crop rotation, early planting and agroforestry were identified from the eligible studies. A total of 62 plant species were documented for protecting crops from pests and diseases by local farmers. The top three mentioned plant species were <i>Allium cepa</i>, <i>Nicotiana tabacum</i>, and <i>Tagetes minuta</i>, each of them having a frequency of five (5).
