The agricultural industry is vital to the country’s economy and significantly affects climate change. Environmental concerns have raised the demand to investigate traditional farming practices and to adopt sustainable practices for increasing agricultural output by bringing innovative and sustainable technologies to improve farm production and to ensure the minimization of plant protection products (PPP) that emit harmful emissions to increase sustainability outputs. The untailored use of these PPPs is extremely detrimental to the environment; therefore, products that might improve the yield but are also environmentally friendly must be used. Sustainable agriculture is crucial for achieving the goals of Viksit Bharat, which are possible through climate-resilient technologies. Therefore, it is important to incorporate sustainable technologies in this domain. This study aimed to understand the use of sustainable technologies to increase the agricultural sector and ensure sustainability.
Key words: Agriculture, climate change, climate-resilient technology, intellectual property rights, plant protection.

Reforestation and afforestation initiatives are vital tools for mitigating climate change by sequestering atmospheric carbon in long-lived wood biomass. This study focuses on the carbon sequestration potential of six-year-old Populus deltoids Bartr. Marsh. plantations in Bihar, India. Morphometric measurements revealed significant variations among clones, with clone G-48 exhibiting superior growth characteristics, including height (14.2 m), diameter at breast height (17.51 cm), and crown width (4.83 m). Biomass estimation indicated that G-48 produced the highest biomass (60.69 kg tree-1). Carbon stock analysis revealed G-48’s dominance, with the highest total carbon stock (0.287 q tree-1) and above-ground biomass (0.246 q tree-1). Carbon sequestration assessments showed G-48’s remarkable potential, with the highest CO2 mitigation (129.79 Mg ha-1) and carbon storage from coal substitution (1.83 Mg ha-1). Soil organic carbon (SOC) analysis indicated significant improvements, with G-48 exhibiting the highest SOC levels. The study underscores the importance of clone selection and responsible forest management in maximizing carbon sequestration benefits. These findings contribute to the understanding of poplar plantation dynamics and emphasize the potential of afforestation initiatives in combating climate change.
Key words: Afforestation, biomass, carbon sequestration, populus, SOC dynamics.

This study examines the long-term effects of organic and inorganic fertilizers on soil sulphur (S) dynamics and fractionation in rice-based cropping systems on calcareous soils, addressing critical gaps in understanding S distribution and availability. The findings reveal that prolonged fertilization significantly influences S content across various soil depths, with the most pronounced increases in available S occurring at 30-45 cm, particularly in plots treated with compost. Compost amendments were especially effective in enhancing S availability, promoting greater S accumulation compared to inorganic fertilizers alone. The fractionation analysis highlighted that fertilization strategies and cropping systems affected different S fractions, with organically bound sulphur being the dominant form. Total S content increased substantially with the application of both organic and inorganic fertilizers, with compost at 5 t ha-1 showing the greatest impact. The study also demonstrated that S concentrations increased with soil depth, influenced primarily by organic inputs such as compost. These results emphasize the crucial role of organic inputs, particularly compost, in improving S availability and its distribution within the soil profile, which is essential for optimizing nutrient management in rice-based cropping systems. The research underscores the importance of adopting long-term fertilization strategies that combine organic and inorganic inputs to enhance soil health, sustain crop productivity, and ensure the efficient cycling of essential nutrients like sulphur. By providing insights into the interplay between fertilization practices and sulphur dynamics, the study offers valuable guidance for sustainable agricultural management in ricebased systems, particularly in calcareous soils, where the use of compost can significantly boost available S levels and improve overall soil fertility.
Key words: Compost, cropping systems, sulphur, Integrated Plant Nutrient System, organics.

An experiment was carried out over two consecutive Rabi seasons in 2017-18 and 2018-19 to investigate the impact of biofertilizers and varying levels of sulphur on periodic changes in soil biological properties and yield of mulched Groundnut in Alfisols. The study was conducted in Red ferrogenous lateritic (Alfisols) soil at the College of Agriculture, Dapoli Dist. Ratnagiri (M.S.), India. The experiment included 16 treatments with different levels of sulphur (0, 15, 30, 45 kg ha-1) and biofertilizers such as Rhizobium, phosphorous solubilizing bacteria, and sulphur oxidizing microorganisms, in addition to a control without biofertilizer, along with 100% recommended dose of fertilizers. Enzyme activities and biological properties were monitored periodically. The results indicated that the application of sulphur oxidizing microorganisms at 5 l ha-1 in 200 l of water through drenching, and sulphur at 45 kg ha-1, significantly increased groundnut yield and enhanced soil biological properties, specifically bacterial population and nitrate reductase activity, except for fungi and actinomycetes. In conclusion, the study suggests that the addition of sulphur at 45 kg ha-1 and sulphur oxidizing microorganisms at 5 l ha-1 in 200 l of water through drenching can lead to significant yield increments and improvements in soil biological properties.

The effect of different multiplex yield enhancers was studied on the growth and yield parameters of potatoes which worked variably at different stages of the crop. The treatment T10 [RDF+Annapurna (240 kg ac-1)+Samruddhi (50 kg ac-1) +Zinc high (10 kg ac-1)+Navjeevan G (10 kg ac-1)] which includes a recommended dosage of fertilizer, organic manures, essential nutrients, and biostimulants has shown a positive effect in increasing the plant height (36.00, 48.33, and 46.67 cm), number of branches per plant (5.89, 7.56, and 10.22), number of leaves per plant (65.78, 82.78 and 98.44) at 30, 60 and 90 DAP, respectively and numbers of tubers per plant. The treatment T15 [RDF+Foliar spray (Mahapal+samras+sambrama+Bio jodi)] has recorded the highest yield per plant and hectare (0.54 kg and 17.86 t, respectively) because of the foliar application at the reproductive phase. Whereas the treatment included with Biojodi have recorded the lowest pest and disease incidence. As potatoes are a nutrient-exhaustive crop, combining organic and inorganic sources of nutrient management would be helpful over chemical fertilizers.

Linz-Donawitz (LD) steel slag, a byproduct of steel industry produced in huge amount is a rich source of plant essential and beneficial mineral nutrients. This study aims to evaluate the impact of LD slag (ranging from 0.5-1.0 t ha-1) given with and without 80 per cent recommended dose of NPK fertilizers (RDF) on yield and physico-chemical and biological characteristics of soil under wheat, rice, maize, brinjal, tomato, amaranthus and mustard. The application of LD slag without RDF reduced the soil quality and crop growth and yield significantly. However, in comparison to control, the LD slag applied along with 80 per cent RDF significantly increased soil pH, electrical conductivity, organic carbon, urease and phosphatase activities across majority of crops. The total microbial count (TMC) was reduced in the soil under all crops except wheat and maize under the slag alone treatment. The slag application with 80 per cent RDF enhanced plant biomass and yield of maize and brinjal, but increased biomass and fruit yield alone in mustard and tomato, respectively. The study evidenced that the application of LD slag is useful in improving soil physical and biological status, and improves the crop growth and yield, selectively, even with less NPK fertilizer application.

Steel slag, a waste from steel manufacturing, cannot be directly used in agriculture despite its nutritional characteristics. The present research deciphered the response of sulfur enriched steel slag (16-20% S) on cauliflower, cabbage and capsicum. The performance of steel slag based sulfur fertilizer (SSSF) at 30, 45 and 60 kg S ha-1 with 100 and 50% NPK fertilizer application was evaluated in terms of growth, yield and quality attributes i.e., total antioxidant capacity, ascorbic acid, phenolic content, and pigment system (anthocyanin, lycopene, â carotene, total carotenoid and chlorophyll content). The application of SSSF caused a significant increase (~25%) in economic yield. An increase in physiological and nutritional attributes including antioxidants was also evidenced with the supplementation of the SSSF. The study showed that steel slag based fertilizers can be applied to complement the conventional chemical fertilizers without causing any soil toxicity and phyto-toxicity. In fact, SSSF application helped to save costs (up to 50%) towards NPK chemical fertilizers without any negative impact on the economic yield and nutritional quality of cabbage, cauliflower and capsicum. The study does not reveal any negative effect of steel slag based fertilizer on soil characteristics. Thus, it supports the possibility that an enriched-amended steel slag can be used as source of mineral nutrients in agriculture.
Key words: Steel slag, sulfur fertilizer, brassicacae, economic yield, antioxidant capacity, oxidation stress.
