Pre-emergent herbicides can have negative effects on maize seeds. The objective of this study was to model seed soaking curves through the processing of red-green-blue imagery of maize seeds under the influence of concentrations of s -metol-achlor + atrazine on both the soaking kinetics and primary root emission. Seeds were placed to soak for 114 h in Petri dishes containing aqueous solutions of a herbicide containing s -metolachlor (290 g l -1 ) + atrazine (370 g l -1 ) with the following concentrations: 0% (water only), 2, 5, 10, 20 and 50%, based on the recommended dose (4.0 l of the commercial product per hectare). The images were systematically taken from a flatbed scanner with artificial light control. The red excess index was adapted to improve image segmentation. From the binary masks applied, the soaking curves for each herbicide concentration were obtained using estimates of seed intumescence over time. The soaking curves were described by fitting Peleg’s model. The herbicide concentration has signifi cant effects on both the absorption rate and primary root emission; the absorption rate was reduced by 50%. A concentration of s -metolachlor (290 g l –1 ) + atrazine (370 g l –1 ) in aqueous solution that is above 20% can fully inhibit seed germination.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47738281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used NDVI, ET, and LST satellite images collected by moderate resolution imaging spectroradiom eter and tropical rainfall measuring mission sensors to investigate seasonal and yearly vegetation dynamics, and also the influence of climatological factors on it, in the area of the Caspian Sea Watersheds for 2001-2019. The relationships have been assessed using regression analysis and by calculating the anomalies. The results showed that in the winter there is a positive significant cor relation between NDVI and ET, and also LST (R = 0.46 and 0.55, p-value = 0.05, respectively). In this season, the impact of pre cipitation on vegetation coverage should not be significant when LST is low, as was observed in the analysed case. In spring, the correlation between NDVI and ET and precipitation is positive and significant (R = 0.86 and 0.55, p-value = 0.05). In this season, the main factor controlling vegetation dynamics is precipitation, and LST's impact on vegetation coverage may be omitted when precipitation is much higher than usual. In the summer, the correla tion between NDVI and ET is positive and significant (R = 0.70, p-value = 0.05), while the correlation between NDVI and LST is negative and significant (R = –0.45, p-value = 0.05). In this sea son, the main factor that controls vegetation coverage is LST. In the summer season, when precipitation is much higher than aver age, the impact of LST on vegetation growth is more pronounced. Also, higher than usual precipitation in the autumn is the reason for extended vegetation coverage in this season, which is mainly due to increased soil moisture. vegetation dynamics and climatological factors in the ( The relationship","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45597556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to evaluate the effect of different mineral-organic mixtures on changes in soil microbial composition and chemical properties. The design of the pot exper iment included 6 treatments: soil without fertilization – C, soil fertilized with mineral NPK fertilizers – MF, soil with NPK + 3 or 6% lignite and 3% zeolite-vermiculite composite (MF+CW3%, MF+CW6%), soil with NPK + 3 or 6% leonardite and 3% zeolite-vermiculite composite (MF+CL3%, MF+CL6%). The test plants were spring oilseed rape and spring wheat. The highest number of microorganisms was observed: for oilseed rape – in the soil of the MF+CW3% and MF+CW6% treatments, and for wheat – in the soil of the MF+CL3% and MF+CL6% treatments. The maximum percentage increase in the number of analysed micro organisms, for spring rape and spring wheat, respectively, was: bacteria 190% (MF+CW3%) and 1198% (MF+CL3%), mould fungi 221% (MF+CW3%) and 1601% (MF+CL3%), Azotobacter spp. 248% (MF+CW6%) and 251% (MF+CL3%), actinomycet es 116% (MF+CW3%) and 251% (MF+CL3%). The beneficial effect of the applied mineral-organic mixtures on soil biological activity is closely related to the effect of these materials on soil chemical properties, such as pH or electrical conductivity, which was confirmed by the calculated correlation coefficients.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46119376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kahraman","doi":"10.31545/intagr/149295","DOIUrl":"https://doi.org/10.31545/intagr/149295","url":null,"abstract":". The objective of this report was to classify ingredients based on their flowability. Twenty-six different feed ingredients (52 samples) were used including cereal grains, cereal by-products, oilseeds, oilseed meals, and animal-origin products. As an indication of flowability, the angle of repose was determined using a funnel test. In general, high protein oilseed meals had the lowest angle of repose, and therefore they had the highest flow ability with the exception of cottonseed meal. Corn gluten feed and wheat middlings had the highest angle of repose values (39 and 34°, respectively), and therefore they had the lowest flowabil ity. Ingredients with a range of angle of repose values between 22 and 25°, between 27 and 30°, and more than 30°, were categorized as having an easy flow, a moderate flow, and cohesive, respective -ly. The greater the protein content, the smaller the compressibility value ( r = –0.38) and the lower the angle of repose ( r = –0.42). An increase in the ether extract content of the ingredients resulted in a subsequent increase in angle of repose ( r = 0.31) and therefore a decrease in flowability (p<0.05). The angle of repose was positively correlated with compressibility and the Hausner ratio. In conclusion, oilseed meals were classified as “easy flow”, most by-products as “moderate flow”, and cereal grains as “cohesive”.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43104011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gołacki","doi":"10.31545/intagr/148097","DOIUrl":"https://doi.org/10.31545/intagr/148097","url":null,"abstract":". The paper presents the research results of the response of “Ramos” potatoes under impact loading conditions. The parameters characterizing the impact such as: maximum stress, maximum force, impact time, maximum deformation, permanent deformation and restitution coefficient were determined. The extent of the damage was also assessed on the basis of the parameters describing the particular bruise such as: bruise depth and width. The impact parameters were related to the bruise size in order to determine the damage threshold for the potatoes under impact loading conditions and to show which parameters describe the bruise beginning to manifest itself. For the tested potato cultivar with a weight of 160-190 g the initiation of the bruise was found to occur at an impact velocity of 1 m s -1 . This corresponded to a bruise threshold (drop height) of 50 mm. The restitution coefficient changed to an insignificant extent which amounted to 0.44-0.49 in the tested range of the impact velocity which proves that the energy losses during the potato impact are constant and independent of the impact velocity. The maximum stress increased with increasing impact velocity, reaching a constant value of 0.9 MPa for the highest impact velocities. The stabilization of the maximum stress indicates that the damage to the potato tissue was determined by exceeding the specified stress value.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43164076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are affected by serious soil erosion and extensive agricultural activities, the structural and hydraulic properties of particular Entisols may differ. Characterizing soil structure and hydraulic properties is important with regard to the development of an understanding of the hydrology and ecosystem functions of shallow Entisols. X-ray computed tomography was used to characterize and quantify the soil pore structure under four typical land use types (cropland, grassland, tea orchard and forest land) from a hilly landscape in South China and the hydraulic properties of the soil including its saturated hydraulic conductivity and water retention curve were measured. The results showed that the soils under the grassland retained 14 and 21% more water at saturation than those under the cropland and tea orchard, respec-tively. The Entisol in the forest land had a significantly larger macroporosity (0.214 mm 3 mm –3 ) compared with that in the cropland (0.117 mm 3 mm –3 ) and tea orchard (0.131 mm 3 mm –3 ). The contribution of pores with a diameter >4 mm as compared to the total computed tomography derived porosity was 62.4% in the forest land, while this size class contributed 69 and 47.3% to the total porosity in the tea orchard and grassland, respectively. The saturated hydraulic conductivity value was well correlated with the degree of anisotropy and the fractal dimension.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46628367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maize ( Zea mays ) is one of the key crops in the world, taking third place after wheat and rice in terms of cultivated area. This study aimed to demonstrate the potential of non-destructive hyperspectral imaging in the wavelength range of 400-1000 nm to discriminate between and classify maize kernels in three cultivars by using non-destructive hyperspectral imaging in the wavelength range of 400-1000 nm. Three cultivars of maize kernels were exposed to hyperspectral imaging with 20 rep -lications. Predictor variables included 28 intensities of reflection wave for spectral imaging and 4 variables in terms of the weight, length, width, and thickness of a single kernel. The classification was successfully performed through Linear Discriminant Analysis and Artificial Neural Network methods, taking into account 32, 15, and 5 predictor variables. According to the results, Linear Discriminant Analysis with 32 predictor variables is characterized by a high degree of accuracy (95%). The most important predictor variables included the reflection wave intensity of the third peak, the wavelength intensity of 490 nm, the wavelength intensity of 580 nm, and the weight and thickness of a single kernel.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43213037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Souza","doi":"10.31545/intagr/147422","DOIUrl":"https://doi.org/10.31545/intagr/147422","url":null,"abstract":". Superior agricultural yields are obtained from seeds which have a high physiological potential, these are conserved in the post-harvest stage. Thus, it is crucial to implement post-harvest projects with appropriate technologies related to the equipment used and the control of operations. This article presents a review of the technical-kinetic developments in the area of the technology of processing post-harvest soybean seeds, with a particular focus on the evolution and current circumstances of the sector. The findings from this research reveal significant tech nological advances in the drying, processing and storage of seeds at different levels and in various areas of soybean production. In drying systems, temperatures of up to 40°C are recommended, while seed batches must remain static in drying chambers. When processing and standardizing seeds, it is recommended that low-moving equipment and abrupt contacts with mechanical systems, such as pneumatic and gravity separators, be employed to minimize dropping and contact with seeds. In soybean storage, the applications of technologies that can control temperature and relative humidity, and also maintain the storage moisture content in a hygroscopic balance are recommended. The storage of seeds in coated big bags and artificial cooling; a controlled and modified atmosphere serve to preserve essential seed qualities. This review concludes that over the years, there has been a reduction in the cumulative losses due to post-harvest processes.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43343890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tang, Yuemei Zhu, Jinyue Zhang, Yongjian Sun, Na Li, Jun Ma, Zhiyuan Yang","doi":"10.31545/intagr/146934","DOIUrl":"https://doi.org/10.31545/intagr/146934","url":null,"abstract":"Rice is an essential staple food crop for more than half of the world’s population (Xiong et al., 2013). China is the leading rice producer worldwide, and rice plays an important role in China’s grain production. Moreover, over 65% of China’s population consumes rice as their staple food (Zhang et al., 2005). Nitrogen (N) is an essential nutrient in crop growth and plays a decisive role in ensuring a high and stable crop yield (Erisman et al., 2008). Currently, the average N application rate for rice in China is 180 kg ha (Peng et al., 2010; Zhang et al., 2013; Fu et al., 2021). However, the N application rate reaches 350 kg ha in the high-yield Taihu Lake area (Jiao et al., 2018). The past two decades have witnessed increased N fertilizer use, promoting essential rice yield growth in China. Unfortunately, the excessive N input has also caused water eutrophication, soil acidification, reduced rice production efficiency, and other adverse effects (Xia et al., 2016; Townsend et al., 2003). Minimizing N application while avoiding yield reduction is thus a research hot spot in China. Taking into account the disadvantages of predominantly applying base fertilizer and low-efficiency tiller fertilizer in traditional rice production (Ling et al., 2014), most agricultural scientists and technological workers promote the split application of N fertilizer based on leaf age (Ling et al., 1983), site-specific N management based on soil testing (Roland et al., 2019; Ling et al., 2005), real-time N management based on the © 2022 Institute of Agrophysics, Polish Academy of Sciences CHUANHAI SHU et al. 48 relationship between leaf colour and N content (Mohanty et al., 2021), and computer-assisted model optimization to guide fertilization policy (Baral et al., 2021; Sharma S., 2019; Pan et al., 2017; Peng et al., 2002; Angus et al., 1996). These systems have greatly contributed to reduced N use and increased rice yield. Existing studies have shown that improvements in N application methods have more potential than the optimization of the N application rate to further increase rice yield and nitrogen use efficiency (NUE) (Yang et al., 2020; Chen et al., 2015). Increasing the number of N applications in paddy fields from 3 to 4 and 6 to 7 times can notably enhance NUE and achieve the goal of reducing N without affecting the yield. Nevertheless, increasing the frequency of N application can also add to operational costs and induce high water supply requirements, this has limited the promotion of low-intensity/high-frequency N application (Yang et al., 2020; Ohnishi et al., 1999). Rice requires more water than any other cereal grain, it accounts for approximately 60-70% of agricultural water use (Pan et al., 2017) and 50% of domestic water consumption. With increasing demands for industrial water and water for both urban and rural residents, the proportion of water allocated to rice production decreases each year. Therefore, researchers have also conducted many water-","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46369430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
