“…The application of Nano NPK through spraying showed superior results as it had a longerlasting effect and influenced the physiological processes within the plant cells. These findings are consistent with the results reported by Sankar et al (2020), Yomso and Menon (2021), and Massey and Gaur (2014).…”

Maize holds significant importance as a staple crop in the rainfed regions of the Northern plains of Punjab. To maximize the utilization of nitrogen-based fertilizers, the exploration of Nano Fertilizers becomes imperative. This research paper aims to compare the effectiveness of different levels of nano fertilizers, NPK foliar application, and soil application on the growth and yield of Kharif maize (Zea mays L.). The study’s objective is to assess the potential of nano fertilizers as a viable alternative to conventional fertilizers for enhancing crop productivity. A randomized block design with eight treatments and three replications was employed for this investigation. The results indicated that Treatment 8 (50% soil application + 50% Nano NPK) exhibited superior performance in terms of influencing growth attributes and yield of Kharif maize. However, Treatments 50% NPK and Nano NPK, with soil application and foliar application respectively, showcased promising outcomes compared to other treatments. These findings suggest that this combination could be an appropriate management strategy to achieve sustainability. Moreover, the use of Nanoparticle fertilization proves to be a safe method for elevating plant nutrition levels without compromising the environment. This research paper provides detailed insights into the application of Nano urea, Nano NPK, and foliar NPK (19:19:19) in relevant treatments.

“…Greater AGR was mainly due to increased leaf number, leaf area and leaf area duration of plant leading to higher photosynthesis by higher nutrient availability. These results validate the findings of Sankar et al (2020) who also indicated the positive effects of nitrogen on AGR of wheat crop.…”

An experiment was conducted at the Zonal Agricultural Research Station, Gandhi Krishi Vigyan Kendra, University of Agricultural Sciences, Bangalore, with the aim of assessing the impact of nano nitrogen on growth, yield, nutrient uptake, nitrogen use efficiency and enzymatic activity in finger millet cultivation. Among different treatments, application of 75% RDN + seed treatment with nano urea + foliar spray of nano urea at 30 and 50 DAS showed significant improvements in various growth and yield parameters of finger millet. At 90 DAS, it resulted in a remarkable increase in the number of leaves hill-1 (36.73), leaf area (982.90 cm2 hill-1) and leaf area index (3.28). The treatment also led to enhanced growth indices viz., absolute growth rate of 0.74 g day-1, a relative growth rate of 0.029 g g-1 day-1 and a crop growth rate of 24.80 g m2 day-1 during 60-90 DAS period. Significantly, it boosted the grain yield of 3,397 kg ha-1 for finger millet over control. Notably, this treatment exhibited higher NPK (86.56, 25.93 and 55.36 kg ha-1 respectively) uptake at harvest. It also demonstrated superior agronomic efficiency, internal utilization efficiency and nutrient increment efficiency of nitrogen (52.57, 39.24 and 1.40 kg kg-1 respectively). These findings underscore the potential of nano nitrogen in enhancing finger millet growth, increasing yield, optimizing nutrient uptake and improving nitrogen use efficiency in finger millet cultivation.

“…The use of nano NPK fertilizers in potatoes at 50% of the recommended level showed higher values of NPK nutrient use efficiency (Azeim et al, 2020). maximum Agronomic efficiency, apparent nutrient recovery and partial factor productivity were recorded with the application of nano NPK fertilizer alone when compared to other treatments in maize (Sankar, 2020).…”

To ensure the food and nutritional security of the burgeoning global population, food production needs to be doubled in developing countries by 2050. Currently, 30-40% of agriculture production predominantly relies on chemical fertilizers. Precise crop nutrition, low nutrient efficiency, maintaining soil fertility, less damage to soil flora and minimal environmental footprint are the major challenges in modern agriculture. Recent developments in the application of nanotechnology to produce agriculture inputs emerged as a sustainable solution for addressing the challenges in modern intensive agriculture by replacing synthetic bulk fertilizers with their nanoparticle size ( less than 100 nm), superior properties and smart delivery system. Nano fertilizers had the potential to fulfill the requirements of plant nutrition along with imparting sustainability in crop production without compromising the yield of the crops. Some of the current research studies have been reviewed in this paper with citation and these results showed that nano fertilizers have a substantial effect on plant growth, development and physiological parameters including chlorophyll content and photosynthetic activity, it depends on their composition, method and time of application. Their enhanced nutrient use efficiency, correlated with mitigating greenhouse gas emissions. Hence evolving as a cutting-edge approach for sustainable agriculture in climate change is enlightened in this review.
