Under the conditions of Egyptian soils, in which soil pH rises to more than 7.5 - 8.2, phosphorus is deposited form tri calcium phosphate Ca (PO4)2, a complex that not ready for plant. To address this issue, field trial was conducted over 2020/21 and 2021/2022 seasons using split-plot experimental design. The primary objective enhance availability assess its impact on faba bean growth through mineral, bio, organic fertilization, alongside foliar feeding with iron zinc. main factor experiment involved additions, including control (no additions), superphosphate, compost, citric acid, phosphorine, combined treatment compost acid. sub-main considered application microelements, options being no application, zinc application. Various parameters, such as nutrient (N, P, K, mgkg-1) matter (%) were determined at harvest stage. Additionally, chemical constituents K %) straw seeds, along concentrations (mg kg-1) protein assessed harvest. Yield-related components, number pods plant-1, weight seed pod-1 (g), 100 yield (ardb fed-1) (ton fed-1),were also measured. results indicated all additions significantly increased well other compared treatment, (compost + citric) showing superior effects both availability. applications properties clearly discernible. In terms plant-related parameters exhibited highest values, followed by treatments, respectively. Regarding demonstrated most substantial increase traits while realized lowest values. These findings underscore potential specific mitigating phosphorus-related challenges enhancing alkaline soils.

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.
