Challenges and future prospects of agri-nanotechnology for sustainable agriculture in India

Abstract Nanotechnology presenting an inventive frontier in present day agricultural practices is expected to turn into a key force in future by contributing innovative applications. This new approach using nano-principles in agriculture has immense possibilities in handling the world wide challenges of environmental security and sustainability, food production, food safety, food security and global threats of climate change. Nanotechnology is very expansively used in contemporary fields of agriculture, food processing, and food protection, packing industry, dairy industry, packaging, transportation and quality control of agricultural products. It has enormous prospective in making agriculture more proficient and resourceful by using nanoparticles to improve the precision in delivering the nutrients to the specific part at a specific time. Use of nano- based agro-chemicals, ceramic devices, filters; lamination methods have great potential of making agriculture more organized and efficient by transforming the conventional agro-practices. Indian government is also supporting this by making plans to extend support for expansion and commercial applications and acceptance of nanotechnology by encouraging private sector investments and empowering partnerships in public and private sectors . Though nanostructures have enormous benefits in agri-sector, still their relevance and significance had not moved up- to practical field environment. The concerns related to the availability, synthesis, level of toxicity, health hazards, transportation challenges and incongruity of regulatory structure restrict the broad recognition and acceptance of adopting nanotechnology in agriculture. The present paper is an attempt to analyze and propose inputs in addressing the present and future possibilities, perspectives, applications and challenges of incorporating nanotechnology in agricultural sector with a focus on Indian perspective.

Identification of Nutritional Components in Black Sesame Determined by Widely Targeted Metabolomics and Traditional Chinese Medicines.

Chemical composition of secondary metabolites is of great importance for quality control of agricultural products. Black sesame seeds are significantly more expensive than white sesame seeds, because it is thought that black sesame seeds are more beneficial to human health than white sesame seeds. However, the differences in nutrient composition between black sesame seeds and white sesame seeds are still unknown. The current study examined the levels of different metabolites in black and white sesame seeds via the use of a novel metabolomics strategy. Using widely targeted metabolomics data, we obtained the structure and content of 557 metabolites, out of which 217 metabolites were identified, and discovered 30 metabolic pathways activated by the secondary metabolites in both black and white sesame seeds. Our results demonstrated that the main pathways that were differentially activated included: phenylpropanoid biosynthesis, tyrosine metabolism, and riboflavin metabolism. More importantly, the biomarkers that were significantly different between black seeds and white sesame seeds are highly related to the functions recorded in traditional Chinese medicine. The results of this study may serve as a new theoretical reference for breeding experts to promote the genetic improvement of sesame seeds, and therefore the cultivation of higher quality sesame varieties.

Visible and Near-Infrared Diffuse Reflectance Spectroscopy for Fast Qualitative and Quantitative Assessment of Nectarine Quality

Visible and near-infrared spectroscopy has been widely used as a non-invasive and rapid-assessment technique for the quality control of agricultural products. In this study, 325 samples of nectarines representing two commercial varieties, cv. ‘Big Top’ and cv. ‘Magique’, were analysed by visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR). The spectral data were pre-treated and analysed to predict the internal quality of the samples and to discriminate between the two varieties. Good prediction of the internal quality of the samples, using partial least-squares regressions, was observed for both (R 2 P of 0.909 and 0.927 and RMSEP of 0.235 and 0.238 for cv. Big Top and Magique, respectively). Discriminant models, using linear discriminant and partial least-squares discriminant analyses, were built to classify the nectarines. Both methods provided good results with rates of 97.44 and 100% of correctly classified samples. The results indicated that visible and near-infrared techniques can be useful and simple methods for quality control and for the correct identification of nectarines in commercial lines as an alternative to the slower and less accurate manual classification.

Combining spatial and spectral information to estimate chlorophyll contents of crop leaves with a field imaging spectroscopy system

Imaging spectroscopy is widely used in weed recognition, pest monitoring, agricultural product quality control and other precision agricultural fields. In the present study, an in-house-designed/developed field imaging spectroscopy system (FISS, 380–870 nm) was used to obtain the imaging spectra of soybean leaves at 344 wavelengths. The spatial and spectral information including the entropy, mean reflectivity and standard deviation of the leaf images at different wavelengths were extracted; the chlorophyll content was retrieved using multiple linear regression (MLR) together with the spatial information and spectral information, and the results were compared with the results derived with the Analytical Spectral Devices (ASD, FieldSpecFR spectrometer, Analytical Spectral Devices Inc., USA) data that were generated using conventional single sensor spectrometers. The results demonstrated that the entropy, standard deviation and other features of the image were very good indicators of the leaf chlorophyll content, confirming the idea that spatial information can be used to retrieve chlorophyll content, with an accuracy equivalent to that of spectral information, and can provide information that spectral reflectivity cannot provide. Thus, integrating spatial information and spectral information can greatly improve the chlorophyll content retrieval accuracy and reduce the estimation errors by 20 %. Due to the unique measurement method and image-spectrum-in-one feature, the field imaging spectroscopy system (FISS) data can be conveniently used to achieve accurate chlorophyll content retrieval, and the retrieval error was reduced by 30–45 % compared with that for the ASD data. FISS data and the proposed method of integrating both spectral and spatial information of imaging spectroscopy have potential advantages in quantitative spectral analysis applied in agricultural biochemistry related fields.

Associations among Wine Grape Microbiome, Metabolome, and Fermentation Behavior Suggest Microbial Contribution to Regional Wine Characteristics.

ABSTRACTRegionally distinct wine characteristics (terroir) are an important aspect of wine production and consumer appreciation. Microbial activity is an integral part of wine production, and grape and wine microbiota present regionally defined patterns associated with vineyard and climatic conditions, but the degree to which these microbial patterns associate with the chemical composition of wine is unclear. Through a longitudinal survey of over 200 commercial wine fermentations, we demonstrate that both grape microbiota and wine metabolite profiles distinguish viticultural area designations and individual vineyards within Napa and Sonoma Counties, California. Associations among wine microbiota and fermentation characteristics suggest new links between microbiota, fermentation performance, and wine properties. The bacterial and fungal consortia of wine fermentations, composed from vineyard and winery sources, correlate with the chemical composition of the finished wines and predict metabolite abundances in finished wines using machine learning models. The use of postharvest microbiota as an early predictor of wine chemical composition is unprecedented and potentially poses a new paradigm for quality control of agricultural products. These findings add further evidence that microbial activity is associated with wine terroir.

베트남 농산물 유통시스템 현황과 발전 전략

Agricultural marketing in Vietnam is not well developed in many aspects. Because of the small farming scale, it is difficult to apply mechanization and technological progresses. Standardization of quality and packaging of agricultural products is poor, and processing industries are not well developed. Rural infrastructure for agricultural marketing, such as roads, warehouses, ports, and retail-markets, is in poor condition. Market information for farmers is limited and market monitoring system which controls behaviors of traders is poorly developed. Quality control of agricultural products, foodstuff hygiene, and safety guarantee in the market are underprepared. In urban areas, wholesale markets are congested and not modernized, and agricultural products are not traded in a transparent manner. Considering Vietnam’s situations and reflecting upon Korean experiences, it is suggested for the Vietnamese government to adopt the following policy programs: modernization of wholesale markets in large urban areas, construction of marketing facilities in rural areas, provision of grading, standardization, and safety inspection, and market information services, enactment of basic law in agricultural marketing, and nurturing marketing cooperatives.

Progress on the analytical methodology for biological volatile organic compounds

Biological terminal metabolites are volatile organic compounds (VOCs) with strong volatility, containing important bio-information related with biological metabolism. As a crucial research precondition, analytical methodology for biological VOCs has attracted much attention to achieve the adequate composition information of biological VOCs at different physiological status and metabolism phases. In this article, the analytical methodology for biological VOCs is summarized, focusing on the latest advances on sampling and analytical techniques followed by the preliminary application of distilling potential, but crucial, bio-information. Systematic study of the relationship among biological VOCs, biological VOC characteristics and corresponding biomarkers would result in a potential but promising research field, bioodoromics. The concept of bioodoromics is described, and the developing trend of bioodoromics in the future is proposed in this paper. It is believed that bioodoromics possesses the power to describe potential but crucial bio-information related with metabolism pathway. The study of biological VOCs and potential bioodoromics would facilitate relevant fields such as insect prevention, disease diagnosis, criminal track-down, agricultural product quality control and food safety, etc..

Construction and Management Status of Agricultural Traceability Information System of Korea

Recently, as the standard of living is improved and the life expectancy is lengthened by social and economic growth, demands for the safe food have increased to satisfy customer’s values such as the well–being, LOHAS (Lifestyles of Health and Sustainability) etc. As the food safety problems are emerging as social issues, the taste and quality (37.1%) and the safety (24.4%) are represented as the first considerations rather than the cost (6.1%) when customers purchase agricultural and livestock products (CRIC, 2009). As the food safety is critically considered by customers, certification systems such as GAP, HACCP, traceability management etc. have been introduced and operated to guarantee the food safety in foreign developed countries as well as in Korea. Among such certification management systems, the most fundamental method would be the traceability management system (Choi and Baek, 2009). In particular, after international outbreak of mad cow disease (BSE), developed countries such as European countries, Britain, and Japan etc. have promoted the traceability management system focused on livestock products, and are gradually expanding it toward agricultural products, fishery products, and processed food etc. Korea has followed the examples of these developed countries by promoting traceability management systems. The traceability management system for agricultural products was introduced through the amendment of Agricultural Product Quality Control Act in August, 2005, for systematically managing exact traceability information for each production process, distribution process, and sales step of agricultural products. Subsequently, the traceability management system for agricultural products was constructed in 2006 and has been operated up to now (MAF and MMAF, 2005). It is expected that the traceability management system for agricultural products could further improve customer’s reliability by securing the safety, quickly investigating the causes and taking emergency measures when problems arise. This study attempted to examine the construction of the traceability management information system to guarantee the safety of agricultural, livestock, and fishery products from production stage to consumption stage, and to describe the operation status. From the results of survey, the traceability management system for agricultural products currently operated and managed will be evaluated.

Environmental Impact Assessment of Orchard Soilds by the Heavy Metal Concentration in Yantai City of Shandong Province, China

8kg, equivalent to 3.3% of the national consumption, and the application rate in Yantai City is about 9 times higher than the national average. Yantai City is an important base for export of agricultural products. The export value in Yantai city was 1.77 billion US dollar in 2005 and was about 1/20 of the national value. Recently, vegetable production bases are constructed in Yantai City, and mass production of vegetables in a factory is advancing. Major destination for export of agricultural products is Japan, and it faces a difficult phase due to tightening of quality control standard for agricultural products in Japan. Therefore, quality control of agricultural products is essential, and soil quality management is most important for keeping quality of agricultural products. In the present study, scientific data were presented for fertility management of soils in the vegetable field in Yantai City, Shandong Province, and heavy metal concentrations of the soils were measured to assess environmental impact for the purposes of maintenance of vegetable quality and sustainable development of vegetable production.

Sensor Fusion for Quality Control of Agricultural Products

Different tools are described in order to check the complementarity or the redundancy of different sensors before applying a fusion process. Different techniques are described for applying the fusion process at different levels (decision and feature level). Different tools are described in order to check whether the fusion process does or does not improve the performance of the decision. These techniques are successfully applied to two different kinds of fruits: peaches for firmness assessment, and melons for quality prediction, though some problems remain with the inconsistency of the classification provided by an expert in the case of melons.

Use of indirect multivariate calibration for quality control of agricultural products by near infrared spectroscopy

In the near infrared (NIR) region, (λ=800–2500 nm) of the spectrum, most organic molecules have weak but reproducibly measurable absorption bands. This phenomenon has been increasingly exploited for the rapid, quantitative analysis of major constituents of agricultural products. As there is strong spectral overlap and an interaction of constituents in NIR, the calibration of instrumentation has to be performed indirectly with a training set of samples applying multivariate methods. A software package for IBM compatible personal computers includes programs to select samples to be used for calibration, to compute multiple linear regression equations, to cross-validate regression equations and to detect unusual samples. These methods are applied to rapidly determine the oil content of over a thousand rapeseed samples of the harvest of 1986. A considerable saving of time, labour, and costs can be achieved, the agreement with the standard laboratory method is very satisfactory.
