“…Applied nanofertilizers can mediate plant tolerance and mitigation of salinity through many mechanisms including enhancing plant retaining of K + and eliminating Na + , maintaining reactive oxygen species (ROS) homeostasis, increasing nitric oxide production, and lowering lipoxygenase activities (Singh et al 2023a). Many approaches have been applied to ameliorate salinity including nanomaterials such as nanofertilizers (Ibrahim and Hegab 2022;Singh et al 2024a), nano-biochar (Rasheed et al 2024), nano-amendments like sulfur (EL-Madah et al 2024), organic fertilizers (Elshaboury et al 2024), biostimulants (AbdEL-Azeiz and Faiyad 2024), and nano-priming of seeds (Zhao et al 2024). Therefore, this investigation aimed to evaluate the effect of foliar application of nano-NPK and nano sulfur using different doses on the growth, and chemical constituents of Khaya senegalensis Desr A. Juss during the seedling growing stage.…”

OIL salinity is considered a serious and limiting factor reducing the crop productivity in particular under arid, and semi-arid conditions. Pot experiments were conducted at the Ornamental Department of the Horticulture Research Station in Sakha, Kafr El-Sheikh Governorate, Egypt during the season of 2021 and 2022. This study aimed to evaluate the effect of foliar application with nano-NPK and nano-sulfur using different doses on the growth and chemical compounds of Khaya senegalensis L. under salinity stress. The studied treatments were mineral NPK fertilizer at 5 g L -1 (as a control), applied nano-NPK at 1, 2 and 3 ml L -1 , besides three combinations of nano NPK (2 ml L -1 ) and applied nano-sulfur at 1, 2 and 3 ml L -1 , separately. The obtained results showed that the treatment of nano-NPK 2 ml L -1 + nano-sulfur 2 and/or 3 ml L -1 significantly increased plant height (cm), stem diameter (cm), fresh and dry weights of vegetative parts per seedling (g), membrane stability index, as well as root length (cm), number of roots and root fresh and dry weights per plant. The superiority of the nano-NPK at 2 ml L -1 + nano-sulfur at 2 ml L -1 treatment comparing with the control in both seasons. Most treatments recorded significantly higher chlorophyll a, b, carotenoids, catalase and peroxidase activity in the leaves than control. A superiority was found after applying nano-NPK 2 ml L -1 + nano-sulfur 2 ml L -1 in both seasons for nitrogen, phosphorus and potassium content in the leaves, which was significantly increased over the control.

Over the years, the changes in the agriculture industry have been inevitable, considering the need to feed the growing population. As the world population continues to grow, food security has become challenged. Resources such as arable land and freshwater have become scarce due to quick urbanization in developing countries and anthropologic activities; expanding agricultural production areas is not an option. Environmental and climatic factors such as drought, heat, and salt stresses pose serious threats to food production worldwide. Therefore, the need to utilize the remaining arable land and water effectively and efficiently and to maximize the yield to support the increasing food demand has become crucial. It is essential to develop climate-resilient crops that will outperform traditional crops under any abiotic stress conditions such as heat, drought, and salt, as well as these stresses in any combinations. This review provides a glimpse of how plant breeding in agriculture has evolved to overcome the harsh environmental conditions and what the future would be like.

Nano-biochar is a source of blackish carbonaceous material, a prerequisite for sustainable crop productivity. By using a variety of feedstock materials, nanobiochar synthesis can be employed via pyrolysis. Therefore, a project was initiated to explore the morpho-physio-biochemical alteration at the vegetative stage of wheat crops after the foliar application of nanobiochar suspension (NBS). This investigation was conducted at the Botanical Research Area of the University of Lahore in a randomized complete block design (RCBD) arrangement, with four treatments (0, 1, 3, and 5% NBS) by maintaining three replications for each treatment using the wheat variety “Zincol”. Nano biochar suspension in above mentioned concentrations were foliarly applied at the end of tillering/beginning of leaf sheath elongation of wheat seedlings to assess the morphological changes (root length, shoot length, number of leaves, fresh biomass/plant, dry biomass/plant), physio-biochemical alterations (total free amino acids, total sugars, chlorophyll content, protein, phenols, flavonoids), and nutrient uptake (Na, K, Ca, Mg, N, P contents. Our findings indicate that the foliar application of 3% NBS yielded the most favorable results across all measured attributes. Furthermore, Treatment-4 (5% NBS) specifically improved certain traits, including leaf area, total soluble proteins, and leaf calcium content. Finally, all NBS resulted in a decrease in carotenoid and sodium content in wheat seedlings.
