“…Plants desperately need these chemical fertilizers continuously for a long period to replace the nutrients used, this causes the soil's chemical and physical qualities to deteriorate, particularly its fertility, which in turn reduces the quantity of organic matter the soil can contain. Egypt used a lot of chemical fertilizers, which are heavy inorganic fertilizers that are adverse to soil microbial activity and human health (Suhag, 2016), furthermore, horticultural production is continuously influenced by many factors, including the effects of rising environmental pollution (Abobatta, 2020).…”

A two-year investigation was conducted at the experimental farm of Sides Horticulture Research Station, Beni-Suef Governorate, Agriculture Research Center, Egypt, to test organic and NPK fertilizers on the growth, yield, and leaf mineral contents of Murcott Tangerine (Citrus reticulata, Blanco). The experiment included 10 treatments;T1 (100% Mineral NPK fertilizers), T2 (50 % of NPK fertilizer + 50 % yeast vinasse), T3 (50 % of NPK fertilizer + 50 % compost), T4 (50 % of NPK fertilizer + 25 % yeast vinasse + 25 % compost), T5 (25 % of NPK fertilizer + 75 % yeast vinasse),T6 (25 % of NPK fertilizer + 75 % compost), T7 (25 % of NPK fertilizer + 37.5 % yeast vinasse + 37.5 % compost), T8 ( 100% yeast vinasse ), T9 ( 100 % compost) and T 10 ( 50 % compost + 50 % yeast vinasse ). The application of compost and yeast vinasse and its combinations with NPK mineral fertilizers compared with mineral NPK only (control) led to a significantly increased vegetative growth, yield, fruit quality and leaf mineral contents. The highest fruit weight (181.66 g) and yield (72.86 kg/tree) as an average of both seasons were found at (T4). Greatest values of fruit physical and chemical properties were also found with (T4) in both seasonsto improve nodulation and plant growth of leguminous crops.

“…Citrus species stand out as the most productive and widely consumed fruit globally, constituting a vital component of the economy as an evergreen tree cultivated in 140 countries that span across various regions [1]. These regions can be predominantly found in warm temperate zones [2], which offer favorable conditions for citrus cultivation, albeit they are often characterized by arid, hot summers. A prime example of this is the south-eastern region of Spain, renowned for its significant citrus output, attributed to a warm Mediterranean climate and a fertile soil, which collectively foster an optimal growing environment [3,4].…”

An experiment was conducted with two-year-old ‘Fino 95’ lemon plants (Citrus limon Burm. f. cv. Fino) grafted on C. macrophylla (Citrus macrophylla Wester) to study the effects of salinity on plants inoculated with arbuscular mycorrhizal fungi (AMF). Half of the inoculated (+AM) and non-inoculated (−AM) plants were irrigated with half-strength Hoagland solution, and the remainder were inoculated with half-strength Hoagland solution + 30 mM NaCl. Ninety-eight days later, results showed that AMF had alleviated the negative effect of salinity on growth. Inoculation with AMF provided some protection against the damage that salinity caused on cellular membranes and improved the plant water status and turgor under saline conditions (Ψx and Π increased by 16% and 48%, respectively). The responses of mineral nutrition to salinity and AMF treatments were complex. P concentrations in the leaves and roots of +AM plants were lower than in those of −AM plants, but inoculation improved Ca2+ (by 20%), Mg2+ (24%), Fe2+ (21%), and Zn2+ (7%) nutrition in roots and also the Mg2+/Na+ ratio in leaves (33%), reducing the antagonistic effect of Na+ on Mg2+ nutrition in salt-treated plants. AMF could protect plants against salt stress through the maintenance of the gas exchange capacity and due to a better antioxidant response. All these positive effects of AMF contributed to mitigating the harmful effects of salinity stress on the plant growth performance of lemon trees grafted on C. macrophylla rootstock under salinity conditions.

“…Fertile soil considered a basic requirement for citrus cultivation, and , with the extension of citrus cultivation particularly in sandy soil , and the continuous use of inorganic fertilizers for prolonged periods to compensate the used nutrients, leading to the deterioration of soil physical and chemicals characteristics particularly fertility thereby limiting the organic matter in the soil, more attention for using organic and biofertilizers arise ,as there is a strong relationship between soil organic matter content and citrus productivity (Ge et al, 2018). Due to rapid increase of world population which expected reach to 9 billion by 2050 and 12 billion by 2100, there is dramatic increase of food and agricultural commodities demands more than available production (FAO, 2017), so, the greatest potintial to fulfill this gap is to increase the productivity per unit area of cultivated land which may achiveded by, enhancing soil fertility through the use of alternate fertilizers as organic and biofertilizers along with chemical nutrients, in the same time horticultural production is facing various threats like challenges of climate change and increase environmental pollution (Abobatta, 2020), moreover, chemical fertilizers cause series environmental problems, as loss of soil nutrients, soil degradation, and reducing beneficial microorganisms (Suhag, 2016).…”

Citrus trees (Citrus spp.) considered one of the major fruit worldwide, due to continuous and excessive use of synthetic fertilizers, there is a severe hazard to human health and to environment. The integrated fertilizing system in citrus orchards contributes to improve crop production through eco-friendly nutrient supply, producing healthy fruits, enhancing the plant tolerance to biotic stresses, increases growers' profits, and sustains natural resources. There are numerous types of organic fertilizers used in citrus orchards include Compost, Vermicompost, Humic substances, Biochar, Farm manure, and, microorganisms in biofertilizers increase the amount and availability of essential elements to plant, there are various biofertilizers used for different purposes according to the role of microorganisms like Nitrogen-fixing microorganisms like Azotobacter, Azospirillum, Rhizobium and Frankia; Phosphorous solubilizing microbes such as Pseudomonas and Bacillus; Phosphorous mobilizing as Vascular arbuscular mycorrhiza, and Plant growth promoting rhizobacteria (PGPR). There are numerous beneficial effects of organic and biofertilizers include increasing availability of nutrients in soils, increase the tree productivity, enhancing fruit quality, improve soil properties, stimulate microflora population in the rhizosphere, reducing the harmful effects of pathogenic organisms, and improving plant tolerance to biotic and abiotic stresses, particularly using both organic and biofertilizers play a critical role in environmental conservation, they can compensate large amounts of inorganic, fertilizer , reducing the great amount of inorganic fertilizer used indiscriminately in citrus orchards. Using a consortium of organic and biofertilizers with mineral fertilizers provide a positive response in citrus orchards.
