Weather parameters such as temperature, leaf wetness, soil moisture, and relative humidity play a vital role in the growth of diseases in plants. The current study analyses the effect of weather parameters on the development of early blight disease in tomato plants by utilizing traditional machine learning techniques. A real-time dataset TomEBD, comprising five weather parameters, has been employed. Three resampling techniques—Synthetic Minority Oversampling Technique(SMOTE), K-Means SMOTE(KM-SMOTE) and Support Vector Machine SMOTE(SVM-SMOTE)—have been used to balance the dataset. Five different machine learning classifiers—k-Nearest Neighbor(kNN), Support Vector Machine(SVM), Random Forest(RF), Artificial Neural Network(ANN), and Kernel Extreme Learning Machine(KELM)—have been used to classify a plant as healthy or diseased based on meteorological factors. The five classifiers are used on the imbalanced and three balanced datasets, resulting in 20 models. Hyperparameter tuning of all five classifiers has been done for optimization. The results indicate that out of the 20 models evaluated, the proposed model KELM-KM - KELM classifier on KM-SMOTE balanced data outperforms all others with a mean accuracy of 85.82%. A comparison with the existing studies shows that KELM-KM outperforms the state of the art without involving any complex feature extraction techniques. Therefore, it can be used to alarm the farmers for fungicide spray on diseased plants in conducive environments.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 2","pages":"232 - 242"},"PeriodicalIF":1.4,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40003-023-00691-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140431569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Limited water availability negatively affects many physiological processes and the final productivity of sesame. Limited work has been carried out in the past to understand the role of plant growth regulators (PGRs) in modulating sesame growth and development for optimum productivity. A field study was conducted under rainfed conditions to evaluate the response of foliar application of different PGRs such as hormonal-based gibberellic acid (20 ppm); chemical-based thiourea (500 ppm); chemical-constituting structural component-based ortho-silicic acid (380 ppm); and control (water-sprayed) on sesame cultivars: Swetha til, GT-10, TKG-22, and JCSDT-26. The PGRs foliar application was done at the vegetative (25–30 days after sowing), 50% flowering (40–45 days after sowing), and seed development (70–75 days after sowing) stages of the crop. The results revealed that application of different PGRs positively influenced the plant’s growth, physiological, yield and quality traits; however, most effective results were obtained with gibberellic acid (20 ppm), followed by ortho-silicic acid (380 ppm), and thiourea (500 ppm) improved the morphological, yield, and yield-attributing traits. The interaction between PGRs and varieties was found significant and among the sesame cultivars, swetha til followed by JCSDT-29 was found most promising. The application of PGRs has significantly improved the plant height, leaf area, number of branches, capsules, seeds/capsules, seed yield oil content, and fatty acid content compared to the control by gibberellic acid, followed by ortho-silicic acid and thiourea. The interaction between PGRs and varieties was found to be significant, and cultivar Swetha til, a white-colored cultivar performed most superiorly among the different tested cultivars in terms of growth, physiology, yield as well and quality traits when treated with GA3 at 20 ppm. The seed yield was enhanced by 25–26%, 11–12%, and 6–7% with the application of gibberellic acid, ortho-silicic acid, and thiourea, respectively, over control. Considering the findings, it can be concluded that the application of PGRs (thiourea, ortho-silicic acid, and gibberellic acid) significantly enhanced the growth, physiology, yield, and quality of sesame under rainfed conditions; however, GA₃ at 20 ppm was found most effective and may not only enhance the optimum productivity but also effective in improving the quality traits of sesame.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 3","pages":"436 - 449"},"PeriodicalIF":1.4,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140431016","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 experiment utilized a randomized complete block design with four replicates and included six treatments: sole cowpea with 40 kg N ha⁻¹ (T1) and 80 kg N ha⁻¹ (T2), simultaneous sowing of maize and cowpea with 40 kg N ha⁻¹ (T3) and 80 kg N ha⁻¹ (T4) and cowpea sown 3 weeks after maize with 40 kg N ha⁻¹ (T5) and 80 kg N ha⁻¹ (T6). Results showed that sole cowpea had higher light interception and leaf area index than intercropped maize/cowpea, regardless of sowing date and nitrogen supply. The highest photosynthetic rates of cowpea were observed in the intercropping maize/cowpea sown simultaneously with 40 kg N ha⁻¹ and sole cowpea with 80 kg N ha⁻¹. The water use efficiency of cowpea was found to be higher when intercropped with simultaneously sown maize, regardless of nitrogen supply, with values of 3.23 μmol CO₂/mmol H₂O and 3.3 μmol CO₂/mmol H₂O for treatments T3 and T4, respectively. Moreover, the highest cowpea grain yield was observed when maize and cowpea were sown simultaneously with the application of 80 kg N ha⁻¹ (0.99 t ha⁻¹), while the lowest yield was obtained when cowpea was sown 3 weeks after maize (0.37 t ha⁻¹), irrespective of nitrogen supply.

However, there is a scarcity of information regarding the soil mycorrhizal potential, natural mycorrhization, and the spore density of arbuscular mycorrhizal fungi (AMF) associated with <i>P. vulgaris</i> in South-Kivu Province. Sample of rhizospheric soil and roots were collected from famer’s field in three localities in two territories namely Kabare and Walungu. The goal was to determine the natural mycorrhization rate of common beans, AM fungi spore density, and the soil mycorrhizal potential in relation with soil chemical properties. Our findings revealed that bean root colonization was notably high in Katana, Kavumu and Miti, while being comparatively low in Lurhala, Walungu centre, and Nduba. Katana and Kavumu exhibited a high number of spores (242.9 ± 37.8 and 183 ± 13.1 spores.100 g⁻¹ soil, respectively) compared to other sites. Soil mycorrhizal potential was higher in Katana, Kavumu, and Miti sites, located in Kabare territory (10.8 ± 0.7, 9 ± 1.3 and 8.8 ± 0.9 AM fungi propagula g⁻¹ soil). The AM fungi potential was positively and significantly correlated with bean mycorrhizal colonization (<i>p</i> &lt; <i>0.0001</i>). As soil phosphorus (<i>P</i>) content increased, mycorrhization frequency and intensity significantly decreased (<i>r</i> = − 0.69, <i>p</i> &lt; 0.0001 and <i>r</i> = − 0.54, <i>p</i> = 0.002, respectively), along with the soil mycorrhizal potential (<i>r</i> = -0.87, <i>p</i> &lt; 0.0001), regardless the study sites. Conversely, soil pH positively influenced mycorrhizal colonization (<i>r</i> = 0.73, <i>p</i> &lt; 0.0001 and <i>r</i> = 0.54, <i>p</i> = 0.002, respectively), and the soil mycorrhizal potential (<i>r</i> = 0.78, <i>p</i> &lt; 0.0001).

Our results indicate that there is a significant difference between the different provinces of the two regions in several aspects such as the diseases and pests encountered and consequently in the phytosanitary products and control methods, due to the pedoclimatic differences between the two regions. The biological control of insects is carried out by using black soap, neem oil, <i>Melia azedarach</i> (L.) extract, and <i>Bacillus thuringiensis.</i> Rotation with legumes (87.1%), and intercropping mint with aromatic and medicinal plants (22.8%), are the agroecological practices most frequently used by farmers. The relationship between farmers’ practices and parameters related to mint yielding, pathogens involved, and pesticide usage was revealed to be strong and complementary. In summary, our work stands out for its focus on specific regions, its innovative agroecological approach, its in-depth analysis of the chemicals used, and its commitment to close collaboration with the farming community.

However, the participation behaviors in environmental governance represent an ongoing life cycle. Therefore, the study of farmers' sustained engagement in environmental participation is crucial for promoting green and low-carbon development and addressing ecological and environmental problems in China. Drawing on data from the China General Social Survey released in 2017, this paper constructs a theoretical analysis framework of “social network—social fairness perceptions—farmers' continued participation in environmental governance.” Additionally, we employ a structural equation model with bootstrap autonomous sampling method to examine the mediating role of social fairness perceptions. The findings demonstrate that social network, procedural fairness perception, and outcome fairness perception all significantly influence farmers' continued participation in environmental governance. Moreover, social fairness perceptions partially mediate the relationship between social network and farmers' continued participation in environmental governance. Furthermore, higher levels of procedural fairness perception and outcome fairness perception correspond to greater degrees of Chinese farmers' continued participation in environmental governance; conversely, stronger social networks are associated with lower levels of Chinese farmers' continued participation in such activities. This paper aims to elucidate the specific role played by social fairness perceptions within Chinese farmers' continued participation in environmental governance and to actively explore the policy implications.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 2","pages":"319 - 327"},"PeriodicalIF":1.4,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139852324","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}
