Rhizobium and PSB inoculation with DAP application. The area situated at a latitude of 29 0 01' N and longitudes of 77 0 75' E with an elevation of 228 m above mean sea level. The soil of experimental field was well drained, sandy loam in texture, alkaline in reaction (7.81), low in available nitrogen, organic carbon and medium in available phosphorus and potassium with an electrical conductivity of 0.28 dSm -1 . Eight treatments comprising control, inoculation of Rhizobium and PSB with DAP application were tested in RBD with three replications. The chickpea crop was grown with recommended package and practices. The data on growth, yield attributes and yield were estimated as per the standard procedures. The experimental results revealed that growth parameters (plant height, number of branches plant -1 , number of nodules and their fresh and dry weight plant -1 and dry matter accumulation plant -1 ), yield attributing traits viz. number of pods plant -1 , number of seeds plant -1 , test weight and biological yield, grain yield, straw yield in chickpea differ significantly among different treatments. Growth parameters were significantly better in the treatment T8 (Rhizobium + PSB+ DAP). The highest grain yield was recorded in T8 where DAP was applied with inoculation of Rhizobium and PSB. This treatment was superior to the other treatments. Growth and yield attributing characters were comparatively higher in T8. From the study it is concluded that the application of DAP with Rhizobium and PSB inoculation (T8 Rhizobium + PSB+ DAP) gave best results and proved to be beneficial for Kabuli chickpea.

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.

An experiment into the "Performance of wheat (Triticum aestivum L.) on application of nano-fertilizers" was conducted on well-drained sandy soil in response to concerns about food and nutritional security as well as second-generation post-green revolution problems, such as increasing input use with declining efficiency trends, deteriorating soil health, depleting water resources, pollution and narrowing farmer profits. On the wheat variety DBW187 in RBD with three replications, 12 twelve treatments containing control, basal administrations of the required 100% NPK (150:60:40), 75% NPK (112.5:45:30), and Nano N and Nano P in various combinations were tried. The study's findings showed that wheat sprayed with 75% NPK + Nano N and Nano P at 30 and 45 days of growth experienced significantly better growth as evidenced by taller plants (91.23 cm), more tillers per square metre (322.5), higher LAI (0.83), and higher dry matter accumulation per square metre (1532.7), all of which were measured at harvest.

Integration of advanced robotics in agriculture can exponentially boost productivity, alleviate labor shortages, reduce the environmental footprint, and increase the overall profitability of farming. Agricultural robots, often controlled by sophisticated algorithms and AI, offer precision farming capabilities that can enhance yield and quality, while minimizing waste and harmful impacts on the environment. They carry out numerous tasks such as sowing, watering, harvesting, and pest control, more efficiently than traditional methods. The usage of robotic systems enables 24/7 farming operations, overcoming the challenges posed by traditional human labor like working hours and physical exhaustion. The review also explores how this technology can help cater to the rising global food demand in a sustainable way, making it a promising solution to achieving food security in the face of increasing population pressures and climate change impacts. Despite the significant capital investment required for adopting these technologies, the potential long-term benefits, such as reduced operational costs and enhanced farm outputs, underscore their vital role in the future of farming and food production. Concluding that the integration of robotics in agriculture could bring about a revolution in farming practices, ushering in a future of enhanced productivity and sustainability in the sector.
