Excessive nitrogen application can lead to environmental pollution, thus improving soil properties, along with raising fertilizer efficiency is necessary for sustainability in Egypt. Therefore, afield experiments were conducted assess the impact of varying doses recommended (NR) at 100% and 75% as main factor, different rates zeolite addition (0.0, 2.5, 5.0 tons fed-1 ) sub-main factors, spraying titanium 3.0, 6.0 mg L-1) sub-sub-main factors on properties growth performance crisphead lettuce during 2022 2023 seasons. Soil available nutrients, including nitrogen, phosphorus potassium, other such water holding capacity (WHC), electrical conductivity (EC), cation exchange (CEC), determined. Additionally, plant quality traits fresh dry weights, relative content, potassium levels, chlorophyll carotene contents, head weight diameter, total dissolved solids, matter, vitamin C assessed. Results revealed that highest levels phosphorus, post-harvest observed rate (5.0 fed-1), while lowest noted control treatment. WHC, EC CEC increased higher rates, values recorded treated fed-1, followed by 2.5 Plant traits, growth, leaf chemical constituents, photosynthetic pigments, characteristics, quality, gradually improved from 0.0 then fed-1. Similarly, all aforementioned exhibited gradual enhancement 3.0 L-1. Overall, most favorable results achieved plants NR, a simultaneously sprayed Ti Notably, L-1 demonstrated superior compared those NR without titanium.

Onion cultivation faces challenges related to nutrient management, impacting growth, yield and quality. Therefore, this study aimed evaluate the synergistic effects of elemental sulfur beneficial elementson onion quantitative qualitative parameters. The experimental design included treatments with three rates as main factor (control, 150 200 kg fed-1) five elements sub-main (without control, calcium at rate 500 g Ca-EDTA fed⁻¹, zinc Zn-EDTA fed-1, copper Cu-EDTA fed-1and manganese Mn-EDTA fed-1). Results showed that highest (200 combined (500 yielded best outcomes. This combination significantly enhanced availability, photosynthetic efficiency, overall plant health, leading superior growth parameters higher concentrations pigments essential chemical constituents in bulbs. Furthermore, application microelements (copper particular) also exhibited substantial improvements bulb concluded integrated use is crucial for optimizing production. These findings underscore importance balanced management achieving robust high-quality produce, offering a practical solution cultivation.

With increasing municipal and industrial demands for water, its allocation agriculture is decreasing steadily. Irrigated agriculture, both now in the future, will occur areas with limited water resources. Insufficient supply irrigation become norm rather than exception, management move from prioritizing production per unit area to optimizing of consumed. To deal resources, deficit an integral strategy minimizing consumption. In this study, growth, yield, use efficiency, nutritional content onion (Allium cepa L.) were evaluated, as well interacting effects manure treatment on these factors. The research was carried out utilizing a factorial design that arranged split plots included three replications each group. Treatments consisted levels (ETc 100%, ETc 75% 50%) two (with without application). When compared alone, results showed combination application resulted considerable increase plant height, stem diameter, number leaves, bulb weight, nutrient content. 50% had highest efficiency all treatments. Under conditions when there study demonstrates can improve yield.
