Megjegyzések:	Eco-friendly, cost-effective, and long-term solutions for agricultural systems should be explored, such as nano fertilizers, which can be employed as controlled-release or slow-release fertilizers. Therefore, pot experiments were conducted to investigate foliar application of nano-NPK and nano-micronutrients at different concentration on growth, flowering and chemical constituents of Tecoma stans plants compared to the traditional mineral fertilization (NPK) at a private nursery in Mansoura city, Dakahlia Governorate, Egypt over the course of two consecutive 2021 and 2022 seasons. The examined treatments included; 3 g L-1 of mineral NPK fertilizer as control, nano-NPK at 1, 2 and 3 ml L-1 and nano-NPK at 2 ml L-1 + nano-micronutrients at 0.5, 1, 1.5 ml L-1 for each. Results demonstrated that all treatments with nanofertilizers enhanced vegetative growth (plant height, branches number/plant, aerial fresh and dry weights/plant, leaves number and leaf area), root growth (length, fresh and dry weight), membrane stability index, relative water content, and flowering parameters (inflorescence number, and floret number/inflorescence). Additionally, chemical components such as total carotenoids in flowers; leaves chlorophyll a and b, total carotenoids, mineral N, P, and K, and peroxidase and catalase activity in leaves were all enhanced by all nano treatments. Treatment with 2 ml L-1 of nano NPK + 1.5 ml L-1 of nano-micronutrients produced the most statistically significant results for these characteristics. The same treatment exhibited the highest reduction in the period from planting date until emergence the first inflorescence. It could be concluded that applying mixture of nano-NPK fertilizer (2 ml L-1) and nano-micronutrient (1.5 ml L-1) at intervals of 15 days during the growth season achieved the most favorable results in terms of morphological, biochemical, and physiological parameters.

Megjegyzések:	Nanofertilizers have great promise as a tool for environmentally friendly farming. Fertilizers of this type may have a high nutrient use efficiency and a slow-release nutrient profile, meaning they provide plants with the nutrients they need for an extended period of time, unlike mineral fertilizers. A pot study was conducted under plastic house condition at a private nursery in Mansoura City, Dakahlia Governorate, Egypt during two successive seasons of 2021 and 2022. The purpose of this study was to assess the effects of foliar application of nano-NPK and nano-chitosan at varying doses on the physiochemical characteristics and growth of Phildedron plant. Using the treatments of mineral NPK (3 g L-1) as a control and nano-NPK at (1, 2 and 3 mg L-1) as well as 2 mg L-1 nano-NPK combined with (1, 2, and 3 mg L-1) nano-chitosan for each seedling. The obtained results showed that all nano fertilizer treatments increased all studied parameters especially with the treatment of 3 mg L-1 nano-NPK for vegetative growth parameters (plant height, fresh and dry weights of aerial parts/plant and leaf area) by 39.23, 70.84, 51.50 and 15.80%, respectively over the control and highest mean value for root growth (root length, root fresh and dry weights) and superiority chemical constituents (chlorophyll a, b and carotenoids, membrane stability index as well as mineral N, P and K (%), peroxidase and catalase activities) compared to the control treatment. The highest significant values of these traits and chemical constituents were observed for the treatments of either NPK nanofertilizer at 3 mg L-1or nano-NPK at 2 mg L-1plus nano chitosan at 3 mg L-1.

Megjegyzések:	Soil 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.
