Despite the importance, sustainable crop production continues to be an issue because of the pressure put on land, the decline in soil fertility, the buildup of pests and diseases, and no standardized production practices. Production is highly mechanized in temperate regions, whereas, in the tropics, it is still a subsistence crop confined to subsistence farming systems. These issues are compounded by a lack of generically and agronomically improved genotypes adapted to wider agroecological zones with adaptive tolerance to existing and new stresses. In the recent past, significant progress has been made worldwide; however, the outcomes tend to be locality-specific, and cannot be extrapolated, needing decentralization of the current approaches. This review points out that the crop is a critical strategic crop in the Oceania region because of its ability to grow under adverse ranges of agroclimatic conditions and can produce a reasonable yield. The paper continues to emphasize the current trends in emerging modern technology that can be used to efficiently improve and enhance traits of agronomic importance and wider adaptivity. In addition, land use plans, farming systems, and cultural production practices need to be changed for sustainable production. The need for these is further strengthened by pointing out alternative strategies, e.g., using organic matter as a relatively cheap and readily available source of soil nutrients compared to inorganic fertilizers.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135380308","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 research was arranged in a randomized complete block design with two treatment factors, which were the type of boron fertilizer application (soil and foliar fertilizer), and the dose of boron fertilizer (1.5, 3, 4.5, and 6 g plant−1 with 0 g plant−1 as a control). Data were then analyzed for variance differences (ANOVA) with α = 5%, followed by the Tukey test, and contrast orthogonal for comparing treated and control plants. The results showed that the dose of boron fertilizer and the type of fertilizer application used have a significant effect on the physiological activity of the cocoa plant. The dose of boron with soil application affects physiological activity in a linear pattern where each additional dose of boron will increase the activity of nitrate reductase, chlorophyll content, and photosynthetic rate. The dose of boron with foliar application affects physiological activity in a quadratic pattern, where the dose of boron in the range of 3 g plant−1 is the optimum dose that gives maximum results on nitrate reductase activity, chlorophyll content, and photosynthetic rate in the cocoa leaves. Therefore, it is considered that the application of boron fertilizer at a dose of 3 g plants−1 with the foliar application is more efficient in increasing physiological activity compared to the dose of boron with soil application.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87772927","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}

Each succession of crops was evaluated in two years field experiment using a randomized complete block design. Results revealed that oat-corn-corn and pea/triticale-corn-corn successions produced the highest dry biomass (46.5 t ha-1 year-1). The crop succession of berseem-corn-soybean resulted in the lowest biomass (30.8 t ha-1 year-1). The highest net energy for lactation was recorded at oat-corn-corn and pea/triticale-corn-corn successions (303 103 MJ ha-1 year-1).

Ponds are diverse, extremely dynamic, and highly productive as they offer various services like harbor biodiversity, tool for combating water scarcity, have roles in pollution mitigation and carbon sequestration. Ponds also offer sustainable solutions to support climate change amelioration and aquatic resource management. However, ponds are the most neglected aquatic ecosystems, despite their huge ecological functions. Thus, ponds are debasing at an alarming rate as a result of increased anthropogenic activities and anthropogenically driven changes in natural processes, wreaking havoc on ecological health and water quality. In this context, the major threats to ponds include the dumping of solid waste, increased urbanization, pollution, encroachment and climate change which have resulted in the deterioration of ponds over the years. Sustainable management and restoration of ponds are crucial as this ecosystem offers a wide array of ecological functions. As a result, this research aims to assess the current state of ponds in India in terms of monitoring, ecological services provided, and the various threats to which they are subjected. Further, the discussions on management and perspective restoration strategies of this substantial ecosystem are also included. Thereby, this study suggests better conservation strategies for restoration, reclamation, and sustainable utilization of ponds.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75355000","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 results of a study of the dynamics of changes in Rendzik Leptosol and Greyic Phaeozem Vertic forests in the middle mountains of the North-Western Caucasus after clear-cutting in 2010-2020 are presented. Immediately after clearing the forest, areas with varying degrees of disturbance of the soil and vegetation cover were identified in the clearings, from maximum disturbance in the central part of the clearing to slight disturbance on their periphery at different elevations of 540-1600 meters above sea level (masl). The soil covering is represented with Rendzik Leptosol and Greyic Phaeozem Vertic. Among used metrics were temperature, humidity, texture density, penetration resistance, structural and aggregate composition, and other soil parameters. On felling areas, increased temperatures and decreased soil humidity were recorded. The temperature of Rendzik Leptosol at a depth of 10-30 cm changes within the range of 1-15°С in the period 2018-2020. The terrain elevation affects the soil due to the temperature gradient significantly. Rendzik Leptosol is much colder at an elevation 1640 meters above sea level than at 1200 meters above sea level. The temperature of Phaeozem (540 meters above sea level) reaches 20°С during the summer months at a depth of 10 cm. Soils in felling have differences in structural and aggregate composition and water resistance of aggregates. The study results can be used in assessing damage to ecosystems after deforestation and developing methods for accelerating the restoration of soil properties after deforestation. The result of the study can be applied to assess the change in the state of ecosystems after forest degradation. The most informative diagnostic indicators for assessing the state of ecosystems after forest degradation are discussed in the article.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73173999","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}

An analysis of long-term trends over a specific area is required to understand rainfall variability. The aim of this study was to assess climate variability in terms of rainfall magnitude and frequency by analyzing spatial and temporal rainfall trends in Bengawan Solo Sub-Watershed as well as the rainfed rice production. Daily rainfall data from 10 rain gauge stations over the sub-watershed area from the years 1975 to 2020 were used. The data was managed and collected by the Bengawan Solo Watershed authority. Pearson, Mann-Kendall, and Sen’s Slope tests were applied to assess the recorded data correlation, rainfall trends, and magnitude of trends into annual, monthly, and 10-day. The findings of the study indicated the spatial and temporal inhomogeneous rainfall pattern for all locations for 10-day, monthly and annual patterns. The mountainous regions at Tawang Mangu and Ngrambe stations tend to experience an upward trend (positive magnitude), while the coastal regions at Nglirip and Bojonegoro stations have a downward trend(negative magnitude). Those trends also confirmed that coastal regions would be drier than mountainous regions in the future. Understanding this rainfall trend can assist with rainfed farming strategic planning.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83796569","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 Tulis Watershed has an area of 12,750 ha, which is dominated by hilly areas with areas below alluvial-colluvial. This study aimed to map the potential distribution of the landslides in the Tulis Watershed. As the Tulis Watershed has the potential for landslides, this study was conducted by using Shuttle Radar Topography Mission (SRTM) imagery year 2016. This study considered five aspects that affect landslides, namely: geological type, soil regolith depth, fault, slope, and soil texture. Areas in the Tulis Watershed were classified into five levels of landslide potential The following landslide classes and the area they cover were predicted after applying the formula: very low (0%), low (48%, 6,126 ha), moderate (51%, 6,548 ha), high (0.5%, 63 ha), and very high (0.1%, 13 ha). From the results of the level of potential landslides, several prevention and mitigation measures are recommended according to the level. For shallow landslide levels, it is recommended that relocation centers should be set up. In contrast, for those areas with very high landslide potential, it is necessary to mitigate and install Early Warning System (EWS) tools and prepare the community for adaptation.","PeriodicalId":36463,"journal":{"name":"Sains Tanah","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90160828","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}

Linear and nonlinear models showed that fitting Langmuir and Freundlich isotherms is suitable for this study. The isotherm adsorption of glyphosate sequentially occurs in the Freundlich and Langmuir models (Inceptisol + 40^-t ha^-1 RHB > Inceptisol), where the Freundlich model (R² = 0.938) is dominated by glyphosate adsorption on Inceptisol + 40^-t ha^-1 RHB with n of 0.46 and KF of 1.747 mg kg^-1, whereas the Langmuir model (R² = 0.8608) with Qm of 30.01 mg kg^-1 and KL of 0.08 L mg^-1 at a concentration level of 100 ppm and pH of the glyphosate solution 5.20 units. The glyphosate adsorption was also supported by changes in functional groups, where Fourier transform infrared spectroscopy shows a decrease in transmittance in the O-H; C=C; C-O; C-H, and mineral groups, indicating an increase in the adsorption capacity in Inceptisol ameliorated with 40^-t ha^-1 RHB.

A field experiment was conducted to evaluate the influence of biochar-based organic amendments on the soil quality of sandy loam soils under cassava (Manihot Esculenta, Crants)–peanut (Arachis Hypogeae L.) cropping sequence. The treatments were as follows: biochar (10 ton ha-1) and rice straw  (3 ton ha-1)  (B1);  biochar  (10 ton ha-1), cattle manure (10 ton ha-1), and rice straw (3 ton ha-1) (B2);  biochar (10 ton ha-1)  and cattle manure (10 ton ha-1) (B3);  biochar (10 ton ha-1) and cattle manure (10 ton ha-1) plus rice straw mulch (3 ton ha-1) applied on surface soils (B4),  and without organic amendments (B0) as control. Results showed that the biochar-based organic amendments significantly improved several soil quality indicators such as SOC, total N, available P, Ca, cation-exchange capacity (CEC), and aggregate stability but had no significant effect on pH, K, and Mg. Improvement in soil quality was strongly indicated by an increase in the growth and yield of cassava and peanuts. Treatments B1, B2, B3, and B4 generally had a comparable effect on soil parameters and tended to improve the growth and yield of cassava and peanuts. Cassava was responsive to treatments B2 (biochar, cattle manure, and rice straw) and B3 (biochar and cattle manure) with its actual yield of 27 tons ha−1, which is a 40% increase compared with that in the control. As a secondary crop growing after cassava, peanuts also exhibited higher yields in all amended plots compared with that in the control. The highest yield was obtained in B2 (1.38 ton ha−1), followed by B4 (1.36 ton ha−1), B1 (1.33 ton ha−1), and B3 (1.25 ton ha−1).
