Background and Objective: Salinity either saline water of irrigation or soil is considered a major factor in limiting plant growth.Nano fertilizers are used to reduce drastic effect salinity.This study was performed limit salinity on productivity the SiO 2 nano foliar spray growth parameter, yield, chemical composition cucumber (Cucumis sativa) grown under agricultural drainage water.Materials Methods: A field experiment carried out Kasr Rashwan village at Tameya province, Fayoum...

Abstract Legumes' sensitivity to salt is exacerbated under growth conditions requiring nitrogen fixation by the plant. Phosphorus (P) deficiency widespread in legumes, especially common bean ( Phaseolus vulgaris L). To examine performance of P. stress conditions, a field experiment was conducted using two recombinants inbred lines (RILs) 115 (P‐deficiency tolerant) and 147 susceptible), grown different salinity levels (L) (1.56, 4.78, 8.83 dS m −1 as LI, L2, L3, respectively) supplied with...

In Egypt's arid and semi-arid lands where the main olive production zone is located, evapotranspiration higher than rainfall during winter. Limited research has used nanomaterials, especially nano-silicon (nSi) to improve growth, development, productivity of drought-stressed fruit trees, amid global water scarcity problem. To assess role nSi on drought-sensitive 'Kalamata' tree biochemical physiological changes under drought conditions, a split-plot experiment was conducted in randomized...

Plant growth, development, and productivity are adversely affected under drought conditions. Previous findings indicated that 5-aminolevulinic acid (ALA) 24-epibrassinolide (EBL) play an important role in the plant response to adverse environmental This study demonstrated of ALA EBL on oxidative stress photosynthetic capacity drought-stressed ‘Williams’ banana grown Egyptian semi-arid Exogenous application either or at concentrations 15, 30, 45 mg·L−1 significantly restored activity...

Water scarcity, especially in countries like Egypt, is one of the biggest challenges facing agricultural development. Pomegranate (Punica granatum) drought-resistant but only if irrigation can be optimized. This a crucial approach toward country’s The impact deficit on pomegranate growth, yield, and overall fruit quality was observed during this study, which focused two consecutive years from 2023 to 2024 at private farm located El Khatatba, Egypt. It determined that able achieve high level...

Organic fertilization improves soil fertility and ameliorates the deleterious effects of accumulated salts in for sustainable agricultural production. This research was carried out on thirteen-year-old Mexican lime trees to study effect humic acid (HA), applied as (10, 20 or 30 mL·tree−1) foliar (0.1 0.2%) applications, fertility, tree growth, productivity fruit quality. The experiment conducted during 2020 2021 seasons a randomized complete block design twelve treatments with three...

Evolved in South Africa and released to market 2009, the ‘African Rose’ plum has been introduced grown under Egyptian semi-arid conditions since 2010. Within that time, this cultivar faced significant fruit quality issues, mainly poor color low total soluble solids (TSS). Several trials using foliarly applied growth regulators have conducted, but with little conspicuous results on yield quality. There is very limited information about relationship between irrigation regime for cultivar....

Drought is regarded as one of the environmental constraints threatening agriculture worldwide. Melatonin a pleiotropic molecule prevalent in plants capable promoting plant endogenous resilience to many challenges including drought. Banana an important staple food consumed developing countries especially Africa. In this research, we studied role melatonin growth bananas subjected drought under Egyptian semi-arid conditions. To achieve objective, field experiment on banana (Musa spp., cv....

In the light of crop shortage production, water scarcity and environmental pollution. The utilization biofertilizers as an algae extract modern irrigation systems has become paramount important to reduce chemical fertilizers ensure good distribution for plants. Therefore, two field experiments were conducted in Nubaria district at Agricultural Station National Research Centre, El-Behira Governorate within winter seasons 2015/2016 & 2016/2017 demonstrate influence systems, i.e., drip...

Abstract One of the most important simulation models in field water produc"tivity (WP) management world is Aquacrop model, which depends on many factors and conditions related to climate, soil, irrigation water, etc. model program simulates vegetative growth yield both grains, biomass WP. The purpose this study evaluate two Egyptian wheat varieties, Gemeza-9 (G-9) Misr-1 (M-1), under modern systems, sprinkler drip, application algae solution. Experiment location fieldwork for research was...

The nitrogen fixed by blue-green algae could supply rice plants with their needs of nitrogen. Cyanobacteria can fix atmospheric in submerged fields. A field experiment was carried out at Rice Research and Training Center, Sakha Station, Agricultural Center ( ARC ) Kafer EL-Sheikh, Egypt during the summer season 2016 to investigate effect biofertilizers as inoculants (Anabaena oryzae D Nostoc muscorum K) . both cyanobacterial strains were selected according amount indole acetic acid...

The good design of irrigation system is one the main steps extent life system, as well increase cultivated crop productivity by choosing proper components control head unit ( such pump, motor, filters, line pipe, fertilization device, and different attachements).Different types are used according to conditions for agricultural areas.It very difficult find an expert at desired time place correct which varied in models.In this study, problem was be tried solve designing network.A rule-based...

Biogate-fert technique ensures to optimization of fertilizer and water units yield the potato crop. There were two field tests conducted in growing seasons. 2019-2020 2020-2021, at research farm National Research Centre Nubaria region, Egypt study management biogate-fert based on a developed SALTMED model crop under drip irrigation system sandy soil conditions. According findings, demonstrated its capacity forecast moisture availability, yield, total dry matter, nitrogen (ppm) for seasons...

A field experiment was conducted to investigate the changes in soil bacteria when using bio fertilizers such as; azotobacter, bacillus circullans and megaterium sandy soils across varied numbers of cultivated years drip irrigation. Drip irrigation had a significant effect on bacterial levels. The biological qualities improved significantly as number planted under rose. After two cultivation, levels increased 102 times more than uncultivated ground. vertical direction, colonies reduced depth...
