To meet the increasing demand for food due to the increasing population, nitrogen fertilizers are being used extensively. Uncontrolled use of nitrogen leads to decreased soil health along with polluting the environment. Maize is one of the important crops in the rainfed regions of Punjab. Therefore, there is a need to optimize the usage of nitrogen fertilizers and that's where nano fertilizers come in. The current investigation was conducted in an RBD (Randomized block design) with 9 treatments and 3 replications. The study showed that the application of 75 % RDN + foliar spray of nano urea 0.1% at knee high and tasseling stage gave superior results concerning growth and yield attributes in kharif maize. However, since the application of 75 % RDN + 2 foliar spray of nano urea at knee high and tasseling stage was significantly at par with a full doze of RDN, therefore this might be an appropriate management alternative for sustainable cultivation practice of maize.

The current experiment was conducted at Chamelti Agriculture Farm, Shoolini University, Solan during rabi season of 2023-24 to study the effect of different nitrogen levels and nano urea on growth and yield attributes of wheat under mid hills of Himachal Pradesh. The soil of experimental field was sandy loam in texture, medium organic carbon, available nitrogen and potassium, high in phosphorous and neutral in reaction with EC in safer range. The field experiment was laid out in Split plot design consisting of four treatments in main plot and three treatments in sub plot. The treatments of main plot were comprising of four nitrogen levels viz., Control, 50% RDN, 75% RDN and 100% RDN (recommended dose of nitrogen) and three foliar spray of Nano urea in sub plot viz., CRI stage, Tillering stage and Jointing stage. The recommended doses of fertilizers were applied in each plot. The doses of phosphorous and potassium were applied as basal at the time of sowing through SSP and MOP. Nitrogen was applied in two split doses, half dose was applied through urea at the time of sowing as basal dose and remaining half dose was applied in two equal splits at the time of CRI and tillering stage. While, foliar application of nano urea was applied as per treatment @ 3 ml l-1 of water. Other operations were performed as per package of practices of this area. The results revealed that application of 100% RDN recorded significantly higher crop growth characters and yield attributes viz., plant height (cm), number of tillers (m-2), chlorophyll content, dry matter accumulation (g m-2), crop growth rate (g m-2 day-1), number of effective tillers (m-2) and number of grains spike-1. While, foliar spray of nano urea at jointing stage resulted in significantly higher plant height and chlorophyll content. However, Foliar spray of nano urea at tillering stage resulted in significantly higher number of tillers, dry matter accumulation, crop growth rate, number of effective tillers, number of grains spike-1. Spike length (cm) and test weight (g) was higher with the application of 100% RDN and nano urea at tillering stage but the difference was found to be non-significant.

Nitrogen fertilizers play an important role in the cultivation of rice. Excessive and improper usage of Nitrogen fertilizer causes problems on human and environment. It is essential for a suitable alternative source of Nitrogen with reduced harm on environment. Nano nitrogen fertilizers are alternative to conventional fertilizers with slow and control release of nitrogen. An experiment was conducted at the Rice Research Station, Sammanthurai, Sri Lanka during the season of 'Yala 2017' April to July involving the use of NPK fertilizers and Nano-Nitrogen fertilizer to test the growth attributes and yield of rice cultivar 'Bg 250'. The experiment was laid out in the Randomized Complete Block Design with five treatments and four replications and experiment was conducted in plastic pots (25cm height and 40cm diameter). The seeds were wrapped with net cotton cloth and three days after germination, it was transferred to seedling tray. At 12 th day uniform and healthy seedlings were transplanted in the plastic pots. A number of 10 seedlings were raised in each plastic pot. There were altogether 20 plastic pots. Five treatments viz; T1-Control (No fertilizer), T2-100% recommended fertilizer (Urea, TSP and MOP), T3-75% Urea + 25% Nano-Nitrogen (Usual TSP and MOP) fertilizer, T4-50% Urea + 50% of Nano-Nitrogen (Usual TSP and MOP) fertilizer and T5-100% Nano-Nitrogen (Usual TSP and MOP) fertilizer were applied. The results revealed that there were significant (p<0.05) differences between treatments in the tested parameters. The application of 100% Nano-Nitrogen fertilizer has given the highest growth performance with regard to plant height

It is widely accepted that deficiency of macro (nitrogen) and micronutrients (zinc, copper etc.) affects the plant growth and development which cause a significant threat to crop production and food security. The Indian Farmers Fertilizer Cooperative (IFFCO) developed nano-urea (nano-N), nano-zinc (nano-Zn), and nano-copper (nano-Cu) liquid fertilizer formulations to enhance the crop yields, simultaneously addressing the nutrient deficiency, without causing toxicity. Therefore, this study was formulated to evaluate the effectiveness of nano-N (nano-urea), nano-Zn, and nano-Cu at varying N levels [0, 50, 75, and 100% of the recommended rates of nitrogen (RRN)] on maize-wheat and pearl millet-mustard systems during 2019–20 and 2020–21. The results exhibited that the application of nano-N + nano-Zn with 100% RRN exhibited significantly higher grain yields in maize (66.2–68.8%), wheat (62.6–61.9%), pearl millet (57.1–65.4%), and mustard (47.2–69.0%), respectively, over absolute control ...

The results of 600 on-farm trials with 8 crops conducted during winter season in different districts of Rajasthan have proved that the quantity of urea being applied by the farmers to supply nitrogen to the crops can be successfully reduced to half. The yields obtained with 50% less nitrogen plus 2 sprays of nano-nitrogen in standing crops gave yields higher than that applied in most of the 8 crops tested in these trials. Apart from this, effect of the Nano-Zn and Nano-Cu was also evaluated. As the deficiencies of these micronutrients were not universal like nitrogen, the significant responses to these nanofertilizers depended on the magnitude of deficiency of specific micronutrients and the nature of the crops.These results clearly establish that with application of nanofertilizers, the nutrient use efficiency can be significantly enhanced as revealed by 50 per cent saving of urea through 2 sprays of Nano N.Nanofertilizers are considered as a novel approach towards saving of nutrie...
