This study's central premise was that chlorine dioxide's oxidant properties would mimic the signaling properties of radical oxygen species, thereby initiating a cascade of molecular plant defenses, including the synthesis of salicylic acid (SA). This signaling agent then initiates a cascade of pre-defense activities to provide a more rapid and robust natural defense against pathogen attacks. This factorial study included two levels for a foliar chlorine dioxide treatment and two for a bacterial wilt inoculation treatment. The two plant response variables were free and conjugated salicylic acid levels sampled in leaf tissue over two collection dates. Half of the 96 plants were inoculated with a bacterial culture that causes common bean wilt disease. Leaf tissue was harvested 17 to 32 h and 960 h after the wilt inoculation to determine the temporal dynamics of SA due to chemical treatments. Also, PCR tests were used to verify wilt presence in the inoculated plants. Inoculation of the wilt disease did not affect free SA when leaf tissue was sampled from 17 to 32 h. after wilt inoculation. However, chlorine dioxide applied at 400 mg/l and sampled at 20 h after inoculation resulted in a 15-fold increase in free SA over the control. Also, chlorine dioxide applied at 400 mg/l with leaf tissue sampled at 26 h after inoculation resulted in a 33-fold increase in conjugate SA levels compared to the control plants.\u0000Leaf tissue sampled at 960 h after the inoculation showed no free SA differences among the chemical treatments. However, the inoculated plant had a 15.9-fold increase in free SA compared to the non-inoculated plants. The priming effect on kidney bean seedlings using a single chlorine dioxide foliage application temporarily increased free and conjugate SA. The free and conjugate SA levels for the non-inoculated plants returned to baseline levels when sampled at 960 h. These results indicate that primed plants elevate SA up to several weeks with a slow decline back to baseline levels. Stem injection of the bacterial wilt bypassed the immunity mechanisms present in leaves, which significantly increased the wilt injury levels. Stem injection negated much of the foliar defenses, which overshadowed the priming effects of the chemical treatments on plant immunity and foliar defenses. The second leaf sampling on newly formed leaves reveals elevated SA levels in the inoculated plants but not in the non-inoculated plants.","PeriodicalId":337372,"journal":{"name":"Global Journal of Agricultural Innovation, Research & Development","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117053487","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}

Furthermore, we show that livestock economic water productivity is often limited compared to crops, which may hide complex interactions between crops and livestock. These interactions provide diverse and steady sources of income for farmers, ensuring the resilience of farms in the face of climate, biotic, and economic risks. Our findings also suggest that the labor requirements of farming activities are burdensome, particularly for family members.

Because of the comprehensive influence of spatial differentiation conditions, such as temperature, precipitation, soil, rice variety, and irrigation, yield estimation requires integrated modeling that is based on dynamic conditions. These dynamic conditions include geographical background, biological factors, and human impact. Most existing studies focus on the observation and analysis of external factors; only a few reports on yield simulations are coupled with nature, management, and crop growth mechanism. Our study incorporates the crop growth mechanism of rice, along with data of rice varieties, soil, meteorology, and field management, to determine the rice yield in Jiangsu province, China. In addition, we have used a decision support system for the agrotechnology transfer model, along with Coupled Model Intercomparison Project data and geographic information system technology. Our results showed that: (1) A calibrated variety genetic coefficient could simulate rice biomass value (flowering stage, maturity stage, and yield) reasonably. The values of NRMSE (Normalized Root Mean Square Error) between the simulated and measured values after parameter calibration are all less than 10%, the values of d(index of agreement) are all close to 1, the simulated value of yield is in good agreement with the measured value. (2) A linear correlation between the meteorological elements and yield was observed. The linear correlation had regional differences. Notably, an increase in precipitation was conducive to the increase in yield. Except at the Huaiyin site, the other sites showed that the temperature rise could potentially lead to reduced production. We found that an increase in solar radiation was unfavorable to the production of rice in the northern and western sites in the Jiangsu province, whereas it was conducive in the southern and eastern sites. (3) Our study predicted the rice yield from typical sites in the Jiangsu province from 2019 to 2060 in the wake of climate change while excluding the extreme effects of diseases, pests, typhoons, and floods. The order of average yield per unit area is as follows: Xinghua site (8212.76 kg/ha) > Huaiyin site (7912.70 kg/ha) > Gaoyou site (7440.98 kg/ha) > Gaochun site (7512.29 kg/ha) > Ganyu site (7460.88 kg/ha) > Yixing site (7167.00 kg/ha). Notably, the average yields from the Xinghua and Huaiyin sites were higher than that from the Jiangsu province (7617.77 kg/ha). The fluctuation of the yield per unit area at each site was generally consistent with the fluctuation in the overall yield, showing a downward trend and tends to be stable. The dispersion of yield per unit area indicates that Gaochun had the most stable yield per unit area followed by Xinghua, Ganyu, Yixing, Huaiyin, and Gaoyou. The yield per unit area of the Huaiyin and Gaoyou sites was unstable and portrayed the biggest fluctuations.

With this background, the manuscript explores the possibility of employing chickpea isolates to fortify yogurt to improvise protein content along with sensory and physicochemical properties. So far, the literature has shown that protein extracts, when added to yogurt, result in gaining protein content and overall product quality. The yogurt market is growing, and consumers from different countries have expressed their willingness to purchase fortified yogurts to achieve optimum health.

The biological control of the species is done with products based on toxins produced by Bacillus thurigiensis (Bt), as bioinsecticides, or in transgenic plants. After activation by intestinal proteases, these toxins interact with receptors, especially cadherin, leading to death due to the formation of cellular pores. In recent years resistant populations have been identified in the laboratory, which can be a problem if the same patterns are found in crops, reducing their control effect. In this paper, we performed a comparative structural analysis of a mutation region for the gene of this receptor in A. gemmatalis, among resistant and susceptible strains treated with a toxin produced by Bt (Cry1Ac). The HaCad fragment of the cadherin gene was amplified by PCR, sequenced, and analyzed by bioinformatics tools. The PCR results were positive for resistant specimens but not for susceptible strains, suggesting the presence of a mutation in the resistant strain. In the sequenced fragments of the resistant insects, six haplotypes were found, and the originated amino acid sequences demonstrated the modification in four sites, which did not interfere with the three-dimensional shape of the protein. These data showed considerable variation taking into account the size of the fragment, even if they do not affect the final structure of the protein. The results allowed a better understanding of the mechanisms of resistance to Cry1Ac in the species, mainly in the involvement of cadherin in this process.","PeriodicalId":337372,"journal":{"name":"Global Journal of Agricultural Innovation, Research & Development","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114174466","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}

This study was based on data collected using focus group discussion, key informant interviews, and field observation. The results show that P. juliflora has expanded rapidly and invaded valuable grazing and croplands, and settlement areas. The rapid expansion of P. juliflora in the study area is attributed to climate change (increased temperature and declined rainfall), its ecological competition, spreading of seeds by wild animals and pastoral (mobile livestock) livelihood system, and recent occurrences of flood and drought-induced pasture scarcity that has forced livestock to eat more P. juliflora seed pods. Also, delays in the use of land cleared for farming activity have created good opportunities for Prosopis expansion. The perception and views of people on the benefits of P. juliflora and management options vary according to livelihood systems and stakeholder types (e.g., environmental managers and pastoralists). The attempted management strategies to eradicate P. juliflora (cutting, burning, and bulldozering or converting into economic utilization by making charcoal, fodder, and furniture) failed to achieve the intended outcomes. These management interventions failed due to many reasons. Some of these were the rapid rate of P. juliflora expansion triggered by the recurrent drought, severe scarcity of pasture that forced livestock to eat P. juliflora’s seed pods and travel into new areas, inadequate technologies to aid utilization and eradication, inability to collect sufficient quantity of pods to produce fodder for livestock, and absence of sufficient and satisfactory markets for the end-product (fodder). The results generally imply the need for urgent policy and management interventions. This study also highlights important issues that should be considered in introducing and implementing management strategies in the future.","PeriodicalId":337372,"journal":{"name":"Global Journal of Agricultural Innovation, Research & Development","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116273993","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}
