Productive conservation at the landslide prone area under the threat of rapid land cover changes

Abstract Landslides often occur in the study area as a continuation of the erosion process on very thick soil from a series of volcanic ash deposition during the Tertiary and Quaternary periods. Rapid land cover changes from agricultural land into settlement increase runoff significantly causing accelerated soil erosion. Soil conservation approaches using parameters to reduce surface runoff and soil loss are less acceptable in agricultural society. Soil conservation methods aimed at reducing runoff and soil loss are not widely embraced in agricultural communities, efforts in soil conservation must be economically beneficial. Vegetative-based erosion control is the most suitable option for the agricultural communities. However, there needs to be improvements in terms of plant arrangement that is adapted to the spatial arrangement of slopes and is focused on zones along rills and gullies. Selection of tree species planted for erosion control that have the value of increasing economic income is the key to the success of planned soil and water conservation efforts.

Soybean yield and seed quality in equidistant versus non‐equidistant plant arrangements under different densities

Diversity of Thrips Species Associated with Soybean Grown in Different Plant Arrangements at Various Phenological Stages

Changes in crop seeding density may affect the presence of phytophagous organisms, whose development is closely associated with host plants. The main objective of this study was to evaluate the abundance and species composition of thrips (Thysanoptera) collected in soybean plants of two different varieties cultivated in different plant arrangements (row spacing, seed density) at different phenological stages. The research was carried out at two locations in southwest Poland between 2015 and 2018. The herbivores that inhabited the plants were caught using an entomological net. The experiments were conducted using a complete block design with four replications. A total of 20 species of thrips were identified and their dietary specialization was determined with an emphasis on the possibility of feeding on Fabaceae plants. Thrips tabaci, Aeolothrips intermedius, and T. fuscipes were the dominant species within the collected material. The general linear model revealed no significant changes in the number of thrips caused by the row spacing, seed density or soybean variety. The significant factor was the phenological stage. The number of thrips increased significantly during the flowering period and shortly after flowering, making them an important threat to the plants. Therefore, it is crucial to develop innovative pest management strategies tailored to effective soybean cultivation to mitigate potential pest-related challenges.

Bed, ridge and planting configurations influence crop performance in field-transplanted hybrid potato crops

Current cultivation practices for field transplanted potato crops grown from nursery-raised hybrid potato seedlings are mostly borrowed from the tuber-based conventional system. Most studies on field performance of field transplanted seedling crops have largely reported the use of ridged rows and in exceptional cases, the use of beds. It is therefore critical to assess the feasibility of the use of alternative ridge or bed systems for cultivation of field-transplanted nursery-raised potato seedlings considering the differences in physiological behaviour of crops grown from different starting materials. This study assessed the effects of six systems which included bed and ridge systems of different dimensions and planting configurations for field transplanted seedling crops. Field crop establishment, canopy growth and development as well as yield and yield components were assessed. In general, systems that boasted high plant densities resulted in faster canopy development and higher number of tubers and tuber yield. Bed systems (raised and flat beds; 8.0 plants m−2) therefore gave the highest numbers of tubers and tuber yield across all treatments. These systems also produced the most tubers in all tuber size classes resulting in the highest yields in all classes. Standard ridge systems (full- and half ridges; 0.75 m row distance), had the lowest plant populations (5.3 plants m−2) which resulted almost always in fewer tubers and lower yield. Other ridge systems (0.9-m and 0.5-m ridge systems), although having higher plant densities than the standard ridge systems (8.9 and 8.0 plants m−2, respectively) still performed poorer than the bed systems. The small and compact ridges in the 0.5-m ridge system and the compact arrangement of plants in the 0.9-m ridge system caused these effects. Conclusively, based on this study, productivity in field transplanting systems is highly influenced by plant density. Further, cultivation systems boasting higher planting densities should be recommended when the goal for production is to produce large quantities of seed tubers (> 35; ≤ 50 mm).

Root traits and soil legacies drive species competition outcomes

Abstract Plant competition can be affected by plant functional traits but also by differences in fitness mediated by soil microbes. Climatic conditions such as drought further influence plant competition. Yet little is known about how soil microbes and drought interact with plant species that have distinct root traits and how this influences plant competition outcomes. We grew three plant species that co‐occur in temperate grasslands in China (Stipa krylovii, Artemisia frigida, Agropyron cristatum) in monocultures and mixtures and subjected the plant combinations to five soil inocula (root‐associated soil of S. krylovii, A. frigida, A. cristatum, an equal mixture of the three root zone soils and sterilized soil) as well as to a drought treatment. The relative change in plant biomass was used to determine plant competition outcomes. The three species exhibited clear differences in competitive abilities with A. cristatum > S. krylovii > A. frigida, and soil inocula or the drought treatment did not change the order. The relative yield (RY) of plants was affected by soil inocula, drought and plant arrangement. The strongest competitor, A. cristatum, with high total root length, root surface area and root volume experienced more negative biotic feedback, and drought enhanced the magnitude of these negative effects. On the contrary, the most inferior competitor, A. frigida, with high specific root length tended to have neutral or positive biotic feedback, and drought had no effect. Furthermore, the RY and fitness difference (reflected as the competitive ability in the mixture) of the three species were differentially influenced by root traits and plant–soil feedback. RY of A. cristatum could be predicted by the feedback effect in the mixture, and the fitness difference was mainly related to root traits. Both RY and fitness differences of A. frigida (the weakest competitor) could be predicted by root trait differences and feedback effects. Differences in root traits were the best predictors of the intermediate competitor S. krylovii. Our study shows that competition outcomes of co‐existing species depend on root traits and species‐specific PSF effects in mixture. Future work should examine the mechanisms that explain how plant competition and soil microbial heterogeneity act in conjunction with climate change in influencing plant coexistence.

Cooling the high temperature nutrition solution to improve growth, yield and water productivity of hydroponic red lettuce (Lactuca sativa L Var Red rapids) in a tropical location

Red lettuce is preferred because of its high nutritional, vitamin, and antioxidant contents. Hydroponic cultivation has been known to successfully improve the quality and productivity of red lettuce. But the efforts to increase the productivity of hydroponic red lettuce face constraints of high temperatures in the tropics. The aim of this study was to compare the growth, yield, and water productivity of red lettuce in three hydroponic systems namely wick, floating raft, and dry systems by controlling the temperature of the nutrient solutions using protected nutrient containers. The experimental design of randomized complete block split plots with the main plots of the nutrient containers which consisted of three levels: Refrigerated container, styrofoam-insulated container, and bare bucket container in which the nutrient solution was delivered to plants in three separated gutters as the cultivation beds, then recirculated back to the corresponding nutrient container. The secondary plot is hydroponic systems including three systems namely wick, floating raft, and dry systems. The blocks were the arrangement of plants according to the flow direction of the nutrient solution, namely upstream, middle and downstream in each gutter. Each experimental unit was represented by 3 plants. Data sets were analyzed by using analysis of variance and followed by LSD multiple comparisons at the 5% level. The results showed that the temperature of the nutrient solution controlled by the three containers had a significant effect on all observed plant parameters. Meanwhile, the hydroponic systems and the blocks had no significant effect. The use of Refrigerated container showed the best performance in improving the growth, yield, and water productivity of the red lettuce.

Effect of row distance on plant architecture, weed suppression and yield of silage maize (Zea mays L.) and soybean (Glycine max (L.) Merr.) in a pesticide-free cultivation system in Southern Germany

Conventional farming prioritizes monocultures and synthetic chemicals to secure high yields. However, there are a growing number of initiatives worldwide to reduce or eliminate the use of pesticides. One option for pesticide-free weed management is the adjustment of sowing pattern (row distance, plant arrangement, sowing density). This study investigated the effects of an equal distance sowing versus a normal distance sowing (EDS and NDS1) at constant sowing density on plant morphology, growth and yield of silage maize (Zea mays L.) and soybean (Glycine max (L.) Merr.) as well as the weed occurrence. Therefore, a 3-year (2020–2022) pesticide-free, field experiment was conducted at the Heidfeldhof Research Station, University of Hohenheim, Germany. In silage maize, neither plant architecture nor biomass yield showed significant differences between EDS with 0.375 m and NDS with 0.75 m row distance. In contrast, soybean developed a bushier plant architecture with more branches and shorter petioles in EDS with 0.15 m compared to plants in NDS with 0.50 m row distance, demonstrating phenotypic plasticity. A higher number of pods per plant (EDS: 28.05; NDS: 22.73) and seed yield (EDS: 406.58 g m−2; NDS: 389.34 g m−2) indicated the potential for increased yields applying EDS. Crop competitiveness against weeds was higher in EDS than in NDS, especially early in the growing season. The results highlight the importance of EDS as a valuable tool for pesticide-free, non-organic cropping systems through positive effects on crop yield and efficient weed control.

Exploring the Correlation between Morpho-physiological Traits and Growth Attributes Associated with Yield Characteristics in Rice (Oryza sativa L.)

This study aimed to identify the morpho-physiological and growth attributes, and yield associated with yield in rice genotypes. The experiment included 120 rice genotypes and 3 checks, conducted in an alpha lattice design with two replications at the Research Cum Instructional Farm in the Department of Plant Physiology, Indira Gandhi Krishi Vishawavidyalaya, Raipur, Chhattisgarh, during the two consecutive Kharif seasons of 2021-22 and 2022-23. Conventional spacing of 15 x 20 cm and recommended cultural practices were employed. The objective is to improve the overall efficiency and productivity of rice cultivation to meet the needs of a growing population. It is crucial to emphasize the comprehension and enhancement of the fundamental features associated with canopy structure and growth attributes. Improving these morpho-physiological traits is pivotal for boosting rice yield. By studying and refining the arrangement and growth of the rice plant's leaf canopy, the goal is to enhance the efficiency and productivity of rice cultivation. The results indicated that productive tillers (0.335**) and flag leaf area (0.213*) were positively correlated with higher yields. While leaf angles, specific leaf area, and days to panicle initiation showed negative correlations with yield. The leaf area index at flowering was positively correlated with specific leaf area (0.382***) but negatively with grain yield (-0.199*). Specific leaf weight was positively correlated with yield per hectare (0.178*). Understanding these relationships can guide the selection and breeding of rice genotypes with optimal traits for enhanced grain yield and crop performance.

Variation in Soil Hydrothermal after 29-Year Straw Return in Northeast China during the Freeze–Thaw Process

In seasonal agricultural frozen soil areas, the straw return may influence the freeze–thaw characteristics by changing the soil organic matter and porosity. Monitoring moisture and heat in the freeze–thaw period is significant for preventing spring waterlogging and reasonable planting arrangements. However, the effect of long-term straw return on the soil freeze–thaw process is still unclear. In this study, we investigated the dynamics of soil temperature (ST) and soil moisture (SM) between straw-return cropland (SF) for 29 consecutive years and no-fertilization cropland (NF) during freeze–thaw progress in northeast China. The soil in both sites underwent unidirectional freezing and bidirectional thawing processes. The soil freezing and thawing dates in the NF of the profile occurred earlier than that in the SF. The NF had higher frozen depth and freezing rate than the SF and exhibited a larger range of ST variation and higher heat transmission efficiency. The SM showed a declining trend before the ST started to decrease to a freezing point at different depths in both sites. The migrated SM in most soil layers decreased during monitoring. The relationship between SM and negative ST was a power function at different frozen depths. The SM decreased rapidly in the range of −2–0 °C in both sites. During phase changes, the SF and NF consumed 33.0 and 43.6 MJ m−2, respectively. The results can partially explain the response of straw return to soil hydrothermal variation during the freeze-thaw process. This study may provide an integral theory for effectively utilizing agricultural soil hydrothermal resource in northeast China.

Penggunaan Pseudosa japonica (Bambu Jepang) sebagai Sound Barrier Alami di Markas Militer Komando Pasukan Khusus

The development of the times will always be accompanied by an increase in population, so infrastructure and a comfortable place to live are needed. However, currently many residential areas are close to public facilities such as stations, highways, airports, and so on. This condition causes noise intensity. Noise intensity can cause health, psychological, communication and productivity problems. Noise is a source of anxiety or pollution, especially in big cities in Indonesia. So, efforts are needed to deal with this. One solution is a natural barrier using Japanese bamboo plants (Pseudosa japonica). Noise measurements are carried out based on the Decree of the Minister of the Environment Number 48 of 1996, namely in a simple way. This research aims to determine the effect of using noise dampening using Japanese bamboo plants and the factors that influence it From the measurements and tests that have been carried out, it is concluded that this barrier can have a significant influence on noise reduction. Noise has little effect on temperature and altitude. The reason is the position of the building is still higher than the position of the bamboo plants which serve as barriers. The highest Ls values ​​are found on Mondays and Saturdays because these 2 days are the start of community activities and the start of holidays. Based on these results, it is necessary to improve the source and arrangement of Japanese bamboo plants according to technical instructions.

Exploring Herbaceous Plant Biodiversity Design in Chinese Rain Gardens: A Literature Review

Amidst rapid urbanization and escalating environmental degradation in China’s urban areas due to climate change, traditional drainage systems struggle to cope with rainfall, resulting in frequent flood disasters. In response, rain gardens have emerged as ecologically practical stormwater management solutions that integrate urban flood control with landscape design. Leveraging the dual benefits of rainwater purification and aesthetic enhancement provided by vegetation, herbaceous plant-based rain gardens have assumed a pivotal role in green infrastructure. However, dedicated research on the application of herbaceous plants in rain garden design is limited, especially within China’s water-stressed context. This study employs a literature review and case analysis to explore this critical issue. Initially, it delineates the concept of the sponge city introduced by the Chinese government. Subsequently, it reviews concepts and methods of plant biodiversity design in urban settings and rain gardens and elucidates the structure and function of rain gardens. Four Chinese rain gardens in different urban environments (old industrial areas, university campuses, urban villages, and urban highway green belts) were selected to examine the selection and arrangement of herbaceous plants while identifying deficiencies in their designs. Finally, feasibility suggestions are provided for the design of herbaceous plant diversity in Chinese rain gardens. This study’s findings can provide a reference for the planting design of herbaceous plants in rain gardens for other countries and regions with similar climates and environmental conditions.

Implementing biophilic design in architecture through three-dimensional green spaces: Guidelines for building technologies, plant selection, and maintenance

With the growing interest in biophilic design for health, well-being, and sustainability, a large variety of plant-integrated building designs have emerged over the past two decades. The integration of plants into buildings is complex because it requires an in-depth understanding of various challenges and considerations. Current guidelines are mostly limited to two-dimensional green surfaces (e.g. green roofs and walls) and are inadequate for richer types of three-dimensional (3D) green spaces. This study aimed to identify the key requirements for creating 3D green spaces (termed ‘green pockets’) in buildings and to develop tailored guidelines for green pockets regarding building technologies, plant configurations, and maintenance. A mixed-method approach including case studies, interviews, site observations, and document analysis was used to examine three representative examples of green pockets in biophilic buildings. We conducted 21 semi-structured interviews with stakeholders and experts involved in these projects, including the clients, designers, engineers, advisors, and property managers. Based on the findings, we developed a framework to guide green pocket design with key considerations for practical applications. We compiled implementation guidelines covering the construction criteria and technical installations, suggestions for plant selection and arrangement, and maintenance actions for the lasting operation of green pockets. This research is significant in providing design teams and decision-makers with a reference guide for implementing biophilic design in architectural practices, helping them understand the complex challenges of green pocket designs and collaborate on solutions to optimise performance in actual use. The research also stimulates further exploration of more sustainable ‘green’ architecture.

Process arrangement and multi-aspect study of a novel environmentally-friendly multigeneration plant relying on a geothermal-based plant combined with the goswami cycle booted by kalina and desalination cycles

In this study, a novel trigeneration system for cooling, heating, freshwater, and electricity generation, driven by geothermal energy is evaluated from thermodynamics, thermoeconomic, and environmental perspectives. To gain a better understanding of the system's performance, energy and exergy analyses are conducted, and the outcomes are compared with other studies. The proposed structure includes a single-flash geothermal plant, a water desalination unit, the Goswami power and cooling cycle, and the Kalina power cycle. This analysis is conducted using Aspen HYSYS software, and the results demonstrated that the single-flash geothermal plant has the highest irreversibility (48 %), and the major sources of irreversibility among all equipment are the heat exchangers, contributing to 68 % of the total exergy destruction rate. Additionally, it is observed from the thermodynamic analysis results that the energy and exergy efficiencies and the total unit cost of products of the proposed process are 32.28 %, 51.71 %, and 5.66 $/GJ, respectively. According to the results, the production rate of the products is cooling (24.8 m3/h), steam (27.44 m3/h), domestic hot water (209.7 m3/h), fresh water (45.02 m3/h), and electric power (16260 kW). The environmental analysis shows that the new process has zero CO2 emission and can save an annual consumption of petroleum equal to 4325160 L, and when compared to the power plants with natural gas and oil as fuel, CO2 emissions are prevented equal to 5691000 kg/year and 13804740 kg/year, respectively.

Computational neural network for processing light-reflective spectra of plants and remote phytosanitary monitoring of potatoes

The article is devoted to studying the possibility of using the WaveLetNN artificial neural network to analyze the results of remote phytosanitary monitoring of early detection of plants in potato plantings affected by late blight. Various methods for analyzing the spectral characteristics of plant reflection are considered, including the classification method. To detect plants infected with late blight, the WaveLetNN neural network analyzes the light reflective characteristics of potato plants obtained as a result of research (in the range of 300–1100 nm) and calculates the cognitive significance index (CSI = 0...10), which characterizes the intensity of biochemical processes inside plants aimed at countering phytopathogenic microflora. It was found that a significant increase in the CSI index signals infection of plants by phytopathogenic microflora and activation of protective biochemical processes on the part of plants. To reliably indicate infected plants, the WaveLetNN neural network underwent test training on a large number of light reflectance spectra of uninfected plants and plants artificially infected with late blight. The spectral reflectance characteristics of infected and uninfected plants were measured during 3, 4, 7 and 8 days after infection. Processing the obtained spectra using the WaveLetNN neural network made it possible to identify significant differences between the second- and third-order spectral characteristics of uninfected and late blight infected plants on the third day after infection. Moreover, for infected plants the CSI index values were 6.1...6.7, and CSI for healthy plants – 1.9...2.5. The Wave-LetNN neural network eliminates the influence on the light reflectance spectra of the spatial arrangement of plant leaves, unevenness of the soil surface and shading of individual sections of the field, normalizing the spectra to the total intensity of light reflected from the leaves. Thus, the WaveLetNN neural network can be used as the software core of online systems for remote phytosanitary monitoring of potato plants.

A Review on Plant Taxonomy

The Identification and naming of plants has attracted a lot of attention throughout history. The science that investigates, identifies, describes, naming of the plant and classifies all plants. Plant taxonomy includes the description of the variation of plants, the observation of the characters like morphological, anatomical and phylogenic characters of the plants, variation, comparison and the manipulation of the data obtained from the previous information/ data is useful to arrange plants in a system of classification. The 3 aspects of the taxonomy are Identification, Nomenclature, classification are the main activates of the taxonomy. Taxonomy means law full arrangement of plants and it is a process of grouping the plants and other organisms. In ancient days plants the classification of plants was very easier and the classification of made by taking consideration of one or two morphological characters which is known as artificial classification but in course of time the classification of plants underwent many medications were taken place because of technological development. But end the end of 19th century the system of classification based on external morphological characters especially based on floral characters because floral characters are stable when compare to morphological characters while growth of the plants, this system of classification is classical/ alpha taxonomy. In course of time the classification of organisms/plants taken consideration of the multiple allied disciplines like the evidences from Anatomy, Embryology, Palynology, Cytology and Genetics. This type of classification is used to resolve taxonomic problems in addition to morphology this classification special significance which is called as biosystematics. Of course an insufficient number of experts, and the instability of phenotypes, which are easily affected by environmental factors, made this classification meet difficulties. With the advent evidences of the fields of phylogenetic, cladistics, experimental botanical gardens, field study, herbariums, keys, museums, computers and systematics, the artificial classification have progressed to a system of modern/ Phylogenic system of biological classification based on consideration of the evolutionary relationships between organisms and both biotic and abiotic factors. Here, I discussed the history of Identification, nomenclature classification and its different systems, for the identification of plants, the development of various molecular techniques that generate molecular markers has made it possible to accurately identify plants. Here I referred the reviews which gives information of the modern techniques and traditional methods that can be used for identification plant species through genotypic studies based on DNA barcoding.

Ethnoecological Perspectives on Agroforestry Practices for Climate Change Mitigation and Adaptation

This research investigates the ethnoecological perspective of agroforestry practices for climate change mitigation and adaptation. Through a literature review method, we analyze relevant literature from various sources to uncover the relationship between local wisdom and agroforestry practices in addressing the challenges of climate change. Findings indicate that the ethnoecological perspective plays a crucial role in shaping sustainable and adaptive agroforestry practices by integrating local knowledge of local ecology and climate patterns with modern scientific knowledge. Agroforestry not only contributes to mitigating greenhouse gas emissions and carbon storage but also provides effective adaptation solutions through season-based planting arrangements and the cultivation of species resilient to extreme conditions. By recognizing the value of local wisdom and knowledge and actively involving community participation in agroforestry management, we can strengthen the resilience and sustainability of agroforestry systems in facing climate change.

Impact of Urbanization on Environmental Eminence: Moderating Role of Renewable Energy

In the era of modernization, the movement of the multitude from rural to urban regions all over the globe is rising swiftly. This movement crafts so many socio-economic prospects for the masses. However, in chorus, it has made severe challenges for the eminence of the environment due to a decrease in forestation and the arrangement of more buildings and plants, causing CO2 emissions. It is unmanageable to edge the endurance of urbanization, and the issue is how we can switch its adversative effects on the environment. This study investigated the moderating role of renewable energy consumption in the urbanization-CO2 nexus. For this study, twenty-three of the most urbanized economies from around the world were chosen from 1997 to 2021. Three econometrics techniques are applied for empirical investigation: fixed effect model, robust least square and panel quantile regression with twelve model specifications. The dependent variable is carbon dioxide (CO2) emissions. The explanatory variables are gross fixed capital formation, patent application, inflation, financial development, industrial growth, urbanization and interaction term of renewable energy and urbanization. To check the robustness of empirical findings, we used four different proxies of (CO2) emissions and three different proxies of urbanization. In our empirical findings, patent application, inflation and industrial growth are positively and significantly associated with all proxies of CO2 emissions. While financial development is inversely and significantly allied with CO2 emissions. The impact of all proxies of urbanization is positive and significant on CO2 production. But the moderating effect of renewable energy on environmental depredation is inverse and significant. It suggests using clean and renewable energy and developing the financial sector to improve the eminence of the environment. Our research aligns with the sustainable development goals and the corporate social responsibility stream, making some valuable contributions to the body of previously established research.

Lonesome plants: How isolation affects seed set of a threatened dioecious shrub.

Plant reproductive failure is a critical concern for conserving rare and endangered species that typically have low-density and sparse populations. One important factor contributing to reproductive failure is the spatial arrangement of plants within a population, which can lead to isolation and negatively affect seed production, particularly in obligate outcrossers. Additionally, plant size can compound this effect, influencing seed production via multiple processes. Here, we investigate how spatial distribution and size influence the reproductive success of Vasconcellea chilensis, an endemic-threatened papaya species in Chile. We first examined whether V. chilensis can produce seeds via apomixis using pollinator exclusion experiments. We then used Spatial Point Pattern Analysis (SPPA) in three populations to explore the spatial arrangement of plants. Finally, we assessed whether plant size and neighbor distance influence the reproductive success V. chilensis is a dioecious shrub unable to produce fruits through apomixis. The SPPA revealed significant clustering of female and male plants at different spatial scales, indicating a non-random distribution. Moreover, a significant spatial association between the sexes was observed. In two populations, closer proximity to male plants was linked to higher seed production. Our study revealed that the reproductive system of V. chilensis is susceptible to distance-dependent reproductive failure due to pollen limitation. While the species' spatial structure may partially mitigate this risk, female plants isolated from male counterparts will likely experience reduced seed set.
