Life Cycle Assessment of the Farm-to-Retail Carbon Footprint of Crossandra (Crossandra undulaefolia Salisb.) in Karnataka, India
This study evaluates the farm-to-retail carbon footprint of Crossandra (Crossandra undulaefolia Salisb.) production in Karnataka, India, based on primary data collected from 260 farmers during 2024–25. A Life Cycle Assessment (LCA) framework was applied to estimate stage-wise greenhouse gas (GHG) emissions (kg CO₂e) associated with cultivation, post-harvest handling, transportation, and retail operations. The results show that irrigation is the predominant source of emissions, contributing 96.34% (4,243,508.17 kg CO₂e) of total emissions, mainly due to electricity-intensive groundwater pumping from deep borewells. Fertilizer application accounts for 2.22% (97,850.12 kg CO₂e) of total emissions, while packaging contributes 1.42% (62,559.08 kg CO₂e). Emissions from pesticide use, transportation, and retail electricity are negligible, reflecting localized marketing systems with limited cold-chain infrastructure and short transport distances. The average carbon emission intensity is estimated at 64.51 kg CO₂e per kg of flowers, with wide variability across farms (1.23–235.52 kg CO₂e/kg), driven primarily by differences in irrigation practices and input use intensity. The study provides stage-wise evidence to support informed decision-making by policymakers, extension agencies, and supply-chain stakeholders aimed at reducing the carbon footprint of floriculture while sustaining farmer profitability.
A Comparative Study of Traditional and Contemporary Textile Practices in Kiphire District of Nagaland
This study explores generational shifts in textile practices in Kiphire district, Nagaland, comparing traditional and contemporary approaches across six dimensions: fiber usage, sourcing, weaving expertise, function, dyeing methods, and stylistic preferences. Textile traditions in the region are deeply rooted in identity, ecology, and ritual, yet modernization has prompted significant transformations. Using random sampling, 100 participants—50 aged 15–20 and 50 aged above 60—responded to a structured questionnaire. Analysis revealed that traditional textiles relied on natural fibers like cotton and wool (78%) and were sourced through homegrown and community-based means (100%). In contrast, contemporary textiles favored synthetic fibers (63%) and commercial sourcing (97%), reflecting convenience and market dynamics. Weaving, once a women-exclusive craft (99%), has evolved into a gender-neutral skill (83%), indicating broader shifts in societal roles. Traditional garments, primarily used for rituals and seasonal adaptation (100%), are increasingly replaced by fashion-driven, comfort-focused attire (70%) in younger groups. Dyeing has transitioned from eco-friendly, plant-based methods—turmeric, indigo, and natural dyes—to synthetic techniques dominating modern production (88%). Statiscally, traditional clothing emphasizes handwoven wraps, beadwork, and cultural motifs, while contemporary fashion leans toward fusion styles, minimalist designs, and machine-assisted production. These findings reflect a complex interplay between cultural continuity and innovation. The study offers a foundation for textile preservation, sustainable fashion design, and community-centered policy interventions in tribal contexts navigating rapid change.
Technological Advances in Weed Management for Sustainable Crop Production
Globally, weeds are the major obstacle to sustainable crop production, resulting in lower yields, higher labour and chemical input costs, and environmental damage from overuse of herbicides and the ensuing resistance. Rapid developments in robots, artificial intelligence (AI), sensor technology, precision agriculture, and creative non-chemical techniques over the past ten years have opened up new avenues for integrated weed management (IWM). Deep learning-based weed/crop classification, unmanned aerial vehicle (UAV) and hyperspectral imaging, ground robotic weeders, Harvest Weed Seed Control (HWSC), and innovative thermal, laser, steam, and electrical spot treatments are just a few of the recent technological advancements in weed detection, removal, and resistance mitigation that are highlighted in this review. Particularly for large-scale and smallholder systems, we evaluate their efficacy, constraints, cost-benefit factors, and adoption paths. Additionally, we present a flowchart and decision framework for selecting suitable weed management technologies based on crop type, weed species, farm size, and economic, regulatory, and environmental constraints. Finally, we identify research gaps and future directions necessary to ensure these technologies contribute to sustainable weed control, reduced herbicide reliance, and biodiversity conservation.
DYNAMICS OF CARBON POOLS IN DIFFERENT RICE ESTABLISHMENT METHODS
Rice yield and productivity enhancement is a consequence of increased soil carbon. Rice yield and productivity enhancement is a consequence of increased soil carbon which has an important social and economic bearing on the livelihood of people. Soil carbon plays a pivotal role in sustaining rice productivity and ecological stability. Indicators of soil quality are derived from the labile pools of soil organic carbon. Rising awareness and alarm over increasing atmospheric CO2 levels impacting renewed interest regarding the sink potential of soil organic carbon (SOC). Carbon sequestration in agricultural soils has three situations i.e. potential, attainable and actual. The research was designed in a Randomized Block Design (RBD), arranged in three replications and treatments included the growing environment of rice which is transplanted, puddled rice. And three replications and four treatments (Control, TP, SRI and DSR) for the field A3(a) & for B7(a) field. Hyderabad’s climate is tropical characterized by dry, hot summers and mild winters. Investigation entitled “Studies on carbon pools and stocks under different rice establishment methods” was conducted during Kharif season of 2024. The different C fractions were estimated through a modified Walkley and Black method as described. The results of the present study revealed that the soil organic carbon content in soil across the different soil depths studied (0-20, 20-40 and 40-60 cm) varied from 0.22 to 0.46%. Among them, non- significantly increased soil organic carbon in soil (0.46%) was observed with System of rice Intensification method followed by Direct seeded rice method (0.45%) and Transplanted Rice (TP) method (0.45%) compared to control (0.42%) at (0-20 cm) soil depth. The results of the present study revealed that the non-labile carbon content in soil across the different soil depths studied (0-20, 20-40 and 40-60 cm) varied from 0.07 to 0.56%. Among them, significantly higher value of non-labile carbon in soil (0.54%) with SRI and DSR methods compared to TP method (0.14) at (0-20 cm) soil depth. Significantly increased the non-labile carbon content in soil with SRI (0.50%), compared to control (0.12%) at (20-40 cm) soil depth. Significantly increased the non-labile carbon content in soil with DSR method (0.56%), compared to TP method (0.07%) at (40-60 cm) soil depths.
Evaluation of mechanical tools to reduce the number of mandays in weed management of newly established tea plantation
Young tea, being highly susceptible to weeds and subjected to herbicide damage due to drift leads to higher dependence on manual weed control. Therefore, two weeders had developed for evaluating their field performance after modification of traditional weeder and field experiment was conducted at Jorhat, Assam with a view to monitor the severity of weed infestation and tea growth in relation to weed management methods in newly established tea. Manual weeding (cheeling) at various intervals was compared with two types of young tea weeder (Type I and Type II), with or without mulching under randomized block design with four replications. Paspalum conjugatum Berg., Axonopus compressus (Sw.) Beauv. and Borreria hispida (L.) K. Schum. were the dominant weed florae. Results revealed that weed control with young tea weeder (YTW) was superior to that of traditional cheeling and it can save mandays to an extent of 25 – 38 per cent, compared to conventional cheeling during the critical period of weed infestation and the saving in man power requirement was more when the collar of young tea was mulched with dry bamboo leaves and weeding done with YTW. Among the treatments, combination of Tocklai YTW II (Type II) with mulching was found to be the best in respect of less weed density, dry weight and man power requirement. This treatment also recorded the highest values of all the biometric parameters. Hence, a combination of mulching and YTW, particularly Type-II was considered the most appropriate treatment for weed management in young tea.
