Storage of anthropogenic carbon dioxide (CO2) emissions in the soil profile is a current global challenge. Despite greater attention to research investigating the buildup of soil organic carbon (SOC) in the surface soil layer (0‒0.2 m), information on C sequestration rates in sub-soil layers (0‒1.0 m) is scanty in tropical upland crop production systems. We investigated the relationship of inputs of biomass C and C sequestration rates with the sustainability yield index (SYI) of the upland rice-based system in Vertisols of Central India. A randomised block design (RBD) was followed with five treatments viz., T1 = control; T2 = 100

Many underutilized edible fruit species (UEFS) are found in the Indo-Gangetic Plains (IGP), which support food security (FS) for both indigenous people and other dependent communities. Unfortunately, there is little study and fragmented information available about these naturally edible products. The UEFS of the IGP was the subject of a systematic review utilizing the PRISMA protocol, which produced implications for FS and land degradation neutrality (LDN). This review aims to survey, summarize, and annotate the published information about the angiosperms native and naturalized UEFS of IGP to identify and make use of this species, particularly for the sustainable development of this region. A systematic review confirmed that 371 species of UEFS, of which 62 species were threatened and near threatened (TNT)-UEFS. Among the TNT-UEFS, 41 species were threatened, while 21 species were NT. The threatened species were further categorized as per the International Union for Conservation of Nature (IUCN) Red List in the IGP as vulnerable (21 species), endangered (16 species), and critically endangered (four species). This systematic review suggests integration of the native and naturalized UEFS in afforestation and reforestation programs to aid in various ecosystem services. Calamus inermis, Corypha taliera , Licuala peltata, and Saurauia punduana are examples of multipurpose species that require immediate sustainable conservation and cultivation initiatives to save them from extinction in the near future. Multipurpose species such as Aegle marmelos , Buchanania lanzan , Manilkara hexandra , Syzygium cuminii , Tamarindus indica are immensely constructive and climate-smart by surviving in harsh agroclimatic conditions and have great potential for establishment on marginal and wastelands throughout the IGP region. These resilient fruit species enhance biodiversity, ecosystems, and landscapes in addition to providing food for humans. It progressively advances Indi & aacute;s commitment to LDN, combating climate change, and achieving the UN-SDGs, which call for reducing hunger and raising FS by 2030. As a result, the study will offer baseline data for the next investigations and be helpful to policymakers in creating sustainable and scientific policies for the IGP.

The study aimed to assess the effects of combined application of urea nitrogen (N) and tank* silt (TS) on greenhouse gases (GHG) emissions [i.e., carbon dioxide (CO 2 ) and nitrous oxide (N 2 O)] and agronomic productivity of maize‐horsegram system. A factorial [urea (0, 60, 120, and 180 kg N ha −1 )] and tank silt (0 and 30 t ha −1 ) replicated thrice randomized block design was employed for this investigation. Results of the study showed that maize grain yield was significantly influenced by the sole application of both N fertilizer and TS. When both the N fertilizer and TS were combined, the grain yield was significantly ( p < 0.01) improved by 5% (4870 kg ha −1 ) over the highest yield observed under only N. We have noticed a significant ( p < 0.01) residual effect of N and TS on horsegram straw yield during all the years of experimentation. With the increase in N‐rate, there was an increasing trend in CO 2 emission noticed in all the years including the pooled year data. Compared to CO 2 emission, N 2 O emission was greatly influenced by nutrient management and amendment application. Among the seasons, the post‐rainy season ( Rabi ) had a slightly lower emission trend of CO 2 , during all the years as compared to the rainy season ( Kharif ). The observed results marked the marginal increasing trend of cumulative CO 2 (cCO 2 ) emissions with regard to increasing doses of urea. Tank silt addition slightly favoured a CO 2 emissions. The trend of cumulative N 2 O (cN 2 O) emission was greatly influenced by the dose of urea following the order of N 180 > N 120 > N 60 > N 0 . However, N fertilizer application influenced the cCO 2 emissions ( r = 0.83), and significantly increased the cN 2 O emission ( r = 0.99). Therefore, optimum and timely application of urea combined with TS is recommended as an effective strategy to combat GHG‐based emissions (specifically N 2 O based) in semiarid rainfed regions.

The Indian Council of Agricultural Research (ICAR) and the World Bank have collaborated on a project entitled the National Agricultural Higher Education Project (NAHEP) to improve agricultural higher education in India, paving the way for sustainable higher education in agriculture. As part of this project, the present investigation was carried out through national-level workshops involving seven State Agricultural Universities (SAUs) across India, with participants from academia and industry, to strengthen ‘academia–industry collaboration’ through effective linkages. Based on the responses of 199 respondents from academia and industry, the study demonstrates an absolute need for linkages between universities and industries (p < 0.001), which are perceived to help improve higher education sustainably. Academic institutions believe that such linkages benefit students concerning their employability, entrepreneurial skills, and financial support received. At the same time, industries believe that they would benefit from novel technologies and influencing academic curricula. This article also establishes an alliance between some parts of academia and industry in the form of MoUs in the identified areas. However, many other areas need more appropriate linkage models. Both sectors, i.e., academia and industry, concur that such exposure and collaboration between the two entities will help to improve the quality of education. Moreover, such collaborations provide financial support, increase students’ employability, and improve their entrepreneurial skills. Among the areas requiring collaboration, the ‘capacity building of students’ was rated most important by academia and industry. Overall, the present study has significant implications for university administrators and industry leaders involved in enhancing academia–industry cooperation and improving the quality and sustainability of higher education in agriculture. Further, the study greatly contributes to the National Education Policy (NEP) to promote innovation among the student communities through Higher Educational Institutes (HEIs) and to the Sustainable Development Goals (SDGs).

This study investigated the effect of bioinoculants (Bacillus subtilis and Pseudomonas fluorescens) as biopriming agents under varied sulphur (S) fertilizer levels (0, 20, 30, and 40 kg S ha−1) to enhance sulphur use efficiency (SUE) in Indian mustard. The experiment was conducted during the 2018–19 and 2019–20 winter seasons at the research farm of the Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (25°26′ N, 82°99′ E). A randomized block design was employed to assess the combined effect of biopriming and S fertilization on the partitioning of S in different parts of mustard plants, S uptake, SUE, and soil urease, dehydrogenase, alkaline phosphatase, and arylsulphatase activity. Results showed that the application of S fertilizers along with biopriming significantly increased the S content, uptake, and SUE by plants and enzymes involved in the S mineralization process. Application of 40 kg S ha−1 + B. subtilis resulted in the highest S content in the root (0.12%), stover (0.30%), and seed (0.67%), and the highest total S uptake (2.97 g m−2 in the first year and 3.37 g m−2 in the second year), agronomic use efficiency (8.80 g g−1), apparent S recovery (22.37%), urease activity (156.68 µg NH4+ g−1 hr−1), dehydrogenase activity (42.80 µg TPF g−1 24 hr−1), and arylsulphatase activity (39.94 µg pNP g−1 hr−1). However, the highest alkaline phosphatase activity (129.17 µg pNP g−1 hr−1) was found in the treatment that received 40 kg S ha−1 + P. fluorescens. Further, the different indices of SUE revealed that the effect of biopriming was more prominent in apparent recovery efficiency than agronomic SUE and physiological SUE. Conclusively, the present study demonstrated that seed biopriming with B. subtilis along with S fertilization is more rewarding and can promote sustainable production of Indian mustard.

Agricultural and Forest Research and Environmental Management entail significant decisions that can impact research findings. Better findings come from well-managed research. In the research and management, a practical methodology approach is used to improve decision-making and prioritise numerous possibilities and research programmes. However, most research scientists need help setting the priority for the research project. A web-based decision-making system, i.e., the Analytic Hierarchy Process (AHP) methodology, provides support and solutions in prioritising the research project options based on multi-criteria decisions in order to eliminate these barriers in agricultural research and management. Considering these factors, the National Academy of Agricultural Research Management (NAARM), Hyderabad, Telangana, India, devised and developed “AHP Analyser”, a web-based group decision-making tool for prioritising the climate change mitigation options of research projects using an analytic hierarchy approach. It was created with PHP, JavaScript, and MySQL and is available at https://naarm.org.in/ahp/. In the present research article, we have briefly discussed the AHP methodology, analytics of publication on AHP usage, primary features of the AHP Analyser, which was built by using AHP methodology, and a case study that shows how the AHP Analyser was used to mitigate climate change in the forestry sector. Study concluded that AHP methodology can be widely applicable in various sectors for decision making, portfolio management and prioritisation; also contributes to the sustainable development goals (SDGs). Therefore, creating awareness on the advantages of AHP methodology among the researchers is critical to bring quality outputs in the research field.

Stomata are crucial structures in plants that play a primary role in the infection process during a pathogen's attack, as they act as points of access for invading pathogens to enter host tissues. Recent evidence has revealed that stomata are integral to the plant defense system and can actively impede invading pathogens by triggering plant defense responses. Stomata interact with diverse pathogen virulence factors, granting them the capacity to influence plant susceptibility and resistance. Moreover, recent studies focusing on the environmental and microbial regulation of stomatal closure and opening have shed light on the epidemiology of bacterial diseases in plants. Bacteria and fungi can induce stomatal closure using pathogen-associated molecular patterns (PAMPs), effectively preventing entry through these openings and positioning stomata as a critical component of the plant's innate immune system; however, despite this defense mechanism, some microorganisms have evolved strategies to overcome stomatal protection. Interestingly, recent research supports the hypothesis that stomatal closure caused by PAMPs may function as a more robust barrier against pathogen infection than previously believed. On the other hand, plant stomatal closure is also regulated by factors such as abscisic acid and Ca2+-permeable channels, which will also be discussed in this review. Therefore, this review aims to discuss various roles of stomata during biotic and abiotic stress, such as insects and water stress, and with specific context to pathogens and their strategies for evading stomatal defense, subverting plant resistance, and overcoming challenges faced by infectious propagules. These pathogens must navigate specific plant tissues and counteract various constitutive and inducible resistance mechanisms, making the role of stomata in plant defense an essential area of study.

Global warming, threats to humankind as driven by the emissions of different greenhouse gases (GHGs) including carbon dioxide (CO2), is becoming a great concern to deal with the vagaries of climate. Plantation ecotypes with greater carbon(C) sink capability are leading among the potential abatement strategies for sequestration of terrestrial C. The present investigation emphasizes on total C stock and litter C status under 13 years old Swietenia macrophylla (Mahogany) pure plantation in Terai belt of West Bengal, India. Stratified tree technique was adopted to estimate the above ground biomass through non-destructive method whereas quadrate method of sampling was followed for estimating leaf litter. The present investigation showed that the total above ground biomass (AGB) of the plantation was 179.73 Mg ha−1 including 95.02 Mg ha−1 (52.83%) shared by stem and in other hand the branch contributed 55.37 Mg ha−1 (30.81%) and the remaining 29.34 Mg ha−1 (16.32%) by leaves. The below ground (root) biomass (BGB) was assessed to be 53.91 Mg ha−1. The biosphere part recorded C was 109.81 Mg ha−1, comprising the total C of AGB and BGB of 84.47 Mg ha−1 and 25.34 Mg ha−1, respectively. Soil C stock (at 0–60 cm) of 40.36 Mg ha−1 comprised 25.30 Mg ha−1 at 0–20 cm followed by 10.46 Mg ha−1 at 20–40 cm and 4.60 Mg ha−1 at 40–60 cm depth, respectively. The total litter production was 6.92 Mg ha−1 yr−1 in 2016–17 and 8.39 Mg ha−1 yr−1 in 2017–18, respectively. The amount of total C storage of plantation was observed to be 150.17 Mg ha−1, comprising 109.81 Mg ha−1 in biosphere and 40.36 Mg ha−1 in soil. The litter C stock of 3.48 Mg ha−1, was excluded from the ecosystem carbon budgeting (ECB), because it acts as a transitional between lithosphere and biosphere. Conclusively, the mahogany-based plantation is not only remunerative to the farmers but also provisions significant improvement in soil fertility along with C sequestration which deploys a crucial part in the sustainable maintenance of the ecosystem in addition to providing a guideline for ECB of the plantation.

The rate of change in the relative amount of active and passive carbon (AC and PC) due to the land management practices (cropping systems combined with tillage) may vary with soil types depending on their level of chemical and/or physical protection from the decomposition but has rarely been directly measured. We have quantified the C storage potentiality of different soil types, namely old alluvial Inceptisol of Malda and recent alluvial Entisol of Coochbehar in West Bengal (subtropical eastern India) under the influence of different cropping systems (rice-maize: RM and rice-wheat: RW) and tillage practices (zero-tillage: ZT and conventional tillage: CT). The key objective was to demonstrate the short-term impact of conservation agriculture (CA) on soil C dynamics over the conventional practice. Research revealed that after short-term CA, total organic carbon (TOC), AC, PC, and total nitrogen (TN) showed significant (p < 0.05) improvement under the RM cropping system over the RW. The highest TOC content under the RM cropping system was recorded in the sites of Malda over the Coochbehar sites. The ZT significantly (p < 0.05) enhanced the TOC in the upper layers (0–5 and 5–10 cm) and the CT showed improvements in the lower depths (10–20 cm). We observed some irregular variations in the interactions of the cropping system and tillage with respect to different sites. However, the ZT performed better in improving C fractions under RM and RW as compared to CT. The TOC and TN stocks were maximum in the lower depth which was evident in both soil types. The TOC linearly regressed on TN accounted for 94.2% variability (R2 = 0.942) of the C accumulation in soil and vice-versa. The PC was in a significant relationship with TN (R2 = 0.943), but AC was moderately regressed (R2 = 0.851). Lower stratification ratio values in Coochbehar soils (sandy loam in texture) indicated higher profile distribution of AC and PC in the soil profile; while in the Inceptisol, accumulation of the C fractions on the soil surface due to heavy texture resulted in the higher stratification values. The novelty of this study is that old alluvial Inceptisol showed a comparatively greater amount of AC and PC storage capability in comparison with the new alluvial Entisol. Conclusively, our study demonstrated that the adoption of conservation agriculture (CA practice/ZT) in cropping systems with higher C biomass input would significantly enhance the AC and PC fractions; however, the amount of storage is highly governed by the soil type and climatic factors.

In this paper the first results of anisotropy of magnetic susceptibility (AMS) studies carried out on 10 schist samples taken from different depths of a borehole in the vicinity of Singhbhum Shear Zone (SSZ) are presented. A cube of 8 cm3 volume was extracted from each borehole sample and its AMS was measured; the shallowest sample is from 112 m depth, while the deepest is from 850 m depth. In the depth vs. mean magnetic susceptibility (Km) plot, a sharp decrease in the Km values is noted in samples from 547 m and 588 m depths. Microstructural investigation of the different samples reveals presence of thick quartz veins in samples from the above mentioned depths vis-à-vis other samples. Petrographic studies also reveal presence of the mineral "allanite" in sample from 547 m depth, which contained a thick quartz vein. It is thus suggested that studies involving AMS investigation of borehole samples from the top 1 km depth of the region hold promise in mineral exploration studies.

Comparison of the carbon (C) stocks among different soil orders allows us to explore the role of various soil characteristics in long-term C storage and their vulnerabilities. This study quantified and compared the accumulation rates of soil organic carbon (SOC) fractions (in 0-60 cm soil profile) in an Alfisol of Malda (25 degrees 27 ' 33.9 '' N, 88 degrees 19 ' 10.2 '' E) and an Entisol of Cooch Behar (26 degrees 09 ' 62.7 '' N, 89 degrees 53 ' 51.7 '' E) districts of West Bengal, India. We noticed a greater level of SOC (0-60 cm depth) in the Alfisol than the Entisol as the former soils were clayey in nature (fine textured) which provided the maximum stabilization of SOC compared to the Entisol (sandy textured). However, the storage of C fractions showed some peculiar results. The concentration of mineral-associated carbon (Min-C) was more or less similar in both the soil orders, but its stock was maximum in the Alfisol. While in the Entisol, permanganate oxidizable carbon (POX-C) and particulate organic matter carbon (POM-C) stocks recorded maximum among all the studied depths. A positive relation of SOC fractions and stocks with clay (r(2) = >0.500 in the Alfisol; r(2) = >0.700 in the Entisol) indicated the importance of finer fractions in profile storage of C. Min-C contributed to SOC of about 75%-85% followed by POM-C (3.27%-17.87%) and POX-C (2.57%-4.22%). Higher stratification of SOC and POX-C and POM-C fractions was observed in Entisol; while in Alfisol, stratification of Min-C was greater. Overall, this research demonstrated that the Alfisol has a greater potential in stabilizing Min-C than the Entisol with POM-C and POX-C and the distribution of these fractions varied as per its stabilization.
