Precision farming technologies have the potential to revolutionize agriculture by promoting eco-friendly practices. The review explores the potential advantages of precision farming technologies in achieving sustainable and environmentally conscious agriculture. The application of precision farming techniques allows for the targeted use of resources such as water, fertilizers, and pesticides, minimizing waste and reducing environmental impact. By incorporating advanced technologies like GPS, GIS, remote sensing, and data analytics, precision farming enables farmers to make informed decisions based on real-time data, leading to improved crop management and increased productivity. Additionally, precision farming promotes the adoption of site-specific management strategies, taking into account the unique characteristics of each field, optimizing resource allocation, and reducing the risk of environmental pollution. This review highlights the importance of precision farming in achieving eco-friendly agriculture and calls for further research and adoption of these technologies to promote sustainable farming practices.

Eco-challenges like greenhouse gas (GHG) emissions and nutrient depletion are key threats to the health of rice field ecosystems. Biochars (BCs) - porous, carbon-dense materials with substantial surface areas and an abundance of surface functional groups - are emerging as a viable solution for these issues, offering a way to increase rice production and address environmental concerns. Despite this potential, there is still a need for a comprehensive understanding of BCs' performance characteristics and their environmental interactions with rice paddy soils. The beneficial outcomes of using BCs, including enhanced rice growth and yield, decreased nutrient loss, and reduced GHG emissions. Factors like biomass type, pyrolysis temperature, and modification process significantly influence BCs' performance. The use of BCs can boost rice production while mitigating emissions of CO2, N2O, and CH4. They do this by improving soil properties, encouraging microbial diversity, supplying nutrients, and minimizing nutrient losses. However, the potential ecological hazards related to the use of BCs in rice paddies. These hazards include inconsistent research outcomes and the possibility of secondary pollution. Future research must address these challenges to ensure the sustainable application of BCs.

This study was conducted to know the utilisation pattern of Annapurna Krishi Prasaar Seva (AKPS) project by farmers of Nagarkurnool district of Telangana. Among the various projects in operation, Annapurna Krishi Prasaar Seva (AKPS) was selected for the study. Twelve respondents were selected randomly from each village that constituted 120 respondents for the study. It was observed that out of 120 respondents almost two-thirds of farmers (65.00 per cent) were utilising services with 3.33 per cent of farmers using it daily once, 13.33 per cent using it weekly once, 22.50 per cent using it monthly once and 25.83 per cent using it whenever needed. Further, the study also revealed that half of the farmers (50.83 per cent) were utilising services for information regarding crop protection followed by 42.50 per cent for weather information, 39.16 per cent for cultivation practices, 34.16 per cent for market prices and 29.16 per cent for livestock information. Whereas, 27.50 per cent, 24.16 per cent, 20.00 per cent and 15.83 per cent were utilizing Annapurna krishi prasar seva for quality inputs, irrigation practices, alternate crops and post-harvest practices information respectively. From this study it was found that Annapurna krishi prasar seva (AKPS) was a popular ICT and the farmers were interested in getting information which need regular update like quality inputs, information on government schemes, crop protection practices, market prices.

The present investigation was carried out to study the effect of foliar application of nano-fertilizers N and P on yield, and the economics of wheat in Semi-arid and sub-tropical region of Central Plain Zone of Uttar Pradesh. The experiment was laid out in triplicate following a randomized block design with twelve treatments comprising foliar application semi-different doses of Nano N and P. Foliar application of 1st spray of Nano N and P at 30 days after sowing (DAS) + 2nd spray of Nano N and Zn at 45 DAS along with 75% recommended dose of fertilizers (RDF) significantly (P=0.05) increased yield and have better economics. Foliar application of nano-fertilizers leads to significant improvement of crop productivity of wheat in Semi- arid and sub-tropical region of Uttar Pradesh. Moreover, the foliar application of nano-fertilizers, i.e., Nano N has direct role in increasing yield as nutrient get easily available to plant in case of foliar spray.
