“…Our results agreement with [8], who found that organic fertilizing with sheep manure improve flowering parameters and fruit set . [13] discovered that different organic fertilizers significantly increased number of inflorescences per shoot , number of flowers per inflorescences and all vegetative growth traits in olive. [9] discovered that treated olive trees with 20% compost 80% soil led to improvements in leaf mineral content (Na+, K, and P), photosynthetic pigments, plant fruit set and fruiting percentage in olive and [16] stated the availability of the N and P macro components influenced flowering intensity and fruit set in another experiment, sheep dung boosted all flowering characteristics (average number of inflorescences/twigs, flowering density, average number of flowers/inflorescences, number of perfect flowers/inflorescence, and sex ratio) when compared to camel and chicken manure.…”

The experiment was conducted on Rawa area at Al-Anbar governorate, western of Iraq, during 2021 and 2022 seasons by using 72 olive trees (Ashrasi cultivar) treated with 0, 15, and 25 kg per olive tree from composted of common reed waste with cow, sheep, and poultry manure, also tree treated with 0 or 50 liters from aqueous extract of compost. The results of the statistical analysis showed that Olive trees were treated with 25 kg from 80 % common reed waste with 20 % poultry manure compost and its water extract, while improved flowering traits (number of flowers per branch, percentage of hermaphrodite flowers, number of fruit set, percentage of fruiting, and fruit retention compared with control treatment under Iraq western desert conditions.

“…In this context, El-Alakmy et al [59] depicted that applying organic fertilizer particularly fish scrap provided a high olive yield and quality and protected trees from environmental stress. Similarly, Nwaigwe et al [60] elucidated that organic fertilizer, particularly goat manure stimulated sweet potato growth, yield component, and root yield compared to non-fertilized control.…”

Olive productivity should be improved through stimulating nutrition, particularly under poor fertility soils. Consequently, the objective of this study was to assess the efficacy of applying organic and bio-fertilizers on the physiological growth, yield and fruit quality of olive trees under newly reclaimed poor-fertility sandy soil in an arid environment. During a field experiment carried out at El-Qantara, North Sinai, Egypt over two consecutive seasons (2019-2020 and 2020-2021), olive Kalamata trees were evaluated under three organic fertilizer treatments alone or in combination with three bio-fertilizers treatments. Organic fertilizer was applied as goat manure (16.8 kg/tree/year), or olive pomace (8.5 kg/tree/year) in mid-December of each season vs. untreated trees. The bio-fertilizers were applied as N-fixing bacteria (150 g/tree) was inculated in early March of each season, or amino acid mixture (1.5%) was applied three times, at 70% of full bloom, 21 days after full bloom, and a month later in comparison to a non-fertilized trees (control). The cultivar used was Kalamata, a dual-purpose cultivar for oil and table olives whose value increases when processed as table olives. The results indicated that the goat manure followed by olive pomace significantly enhanced photosynthetic pigments (chlorophyll a, b, and carotenoids), leaf mineral contents (N, P, K, Ca, Mg and Fe), tree canopy volume, number of flowers per inflorescence, number of inflorescences per shoot, initial fruit set, fruit retention. For fruit quality, fruit length and width, fruit weight, and total fruit yield was increased compared to the non-fertilized control. Likewise, The bio-fertilizer N-fixing bacteria followed by the amino acid mixture significantly improved all of the aforementioned parameters. Accordingly, it is recommended, both environmentally and economically to utilize organic and bio-fertizers, particularly goat manure combined with N-fixing bacteria, in low-fertility soil to sustain olive production as well as reducing mineral fertilization.

“…The potential effects of Nitrobein biofertilizer and urea-formaldehyde fertilizer on fruit quality and yield are consistent with the findings of Kabeel et al (2005) who concluded that all the treatments under their investigation had a positive and significant impact on fruiting characteristics of "Canino" apricot trees and the best and most effectively were ordinary mineral fertilization plus Nitrobein + Enciabein + Phosphorene and ordinary mineral fertilization plus Nitrobein + Enciabein. El-Alakmy et al (2018) studied Kalamata olive trees and observed that applying 50 g of Nitrobein biofertilizer (N-fixing bacteria) to the trees along with a 1.5% concentration of an amino acid mixture (marketed as Protamine) increased blooming, yield, and fruit quality. (2009) on mango, they studied the effects of three different ureaformaldehyde dosages (1000, 750, and 500 g/tree) and revealed that when compared to 1000 g/tree of conventional urea, urea-formaldehyde at 1000 and 750 g/tree considerably enhanced fruit set, fruit retention per panicle, yield, and improved fruit quality.…”

A significant amount of chemical fertilizers are lost due to their widespread use in regions with high temperatures, which also pollute the ecosystem and lower soil fertility. Consequently, using highly nutritious, environmentally friendly fertilizers that are also compatible with the soil and environment is imperative. The application of fertilizers that give macro-and micronutrients to fruit trees is one of the key components of biofertilizer and nitrogen slow release fertilizers in agriculture. A two-year trial was conducted during the 2021 and 2022 seasons in Keitt mango trees orchard about five years old grown in sandy soil under a drip irrigation system from a well at a private orchard, in New Valley Governorate, Egypt. The main objective of this work is to study the effect of three rates of Nitrobein biofertilizer (0.0, 200, and 400 g/tree) and four rates of urea-formaldehyde fertilizer (0.0, 500, 750, and 1000 g/tree) on vegetative growth parameters, yield and fruit quality of Keitt mango trees. Briefly, Nitrobein and urea-formaldehyde treatments enhanced all studied growth, yield, and fruit quality traits. Nitrobein biofertilizer at 400 g/tree combined with ureaformaldehyde fertilizer at 1000 g/tree treatment proved to be the most efficient treatment in this respect.
