This study
investigated the effects of different nitrogen (N) fertilization rates on the
growth, yield, and grain quality of rice (Oryza sativa L.) in the Nile Delta
region of Egypt. A field experiment was conducted during the 2022 and 2023
growing seasons, using a randomized complete block design with four
replications. The treatments consisted of four N fertilization rates: 0, 75,
150, and 225 kg N ha-1. Results showed that increasing N fertilization rates significantly
increased plant height, tiller number, and grain yield. However, the highest N
rate (225 kg N ha-1) did not result in a further significant increase in grain
yield compared to the 150 kg N ha-1 rate. Grain quality parameters, such as
protein content and amylose content, were also significantly affected by N
fertilization rates. The optimum N fertilization rate for maximizing rice yield
and grain quality in the Nile Delta region was found to be 150 kg N ha-1. This
rate can contribute to sustainable rice production by optimizing yield and
minimizing environmental impacts.

1. 1 Background
Fusarium wilt, caused by the
soilborne fungus *Fusarium oxysporum* f. sp. *lycopersici* (Fol), is a
devastating disease of tomato (*Solanum lycopersicum* L.) worldwide, causing
significant yield losses in both greenhouse and field production systems (Jones
et al., 2013). The fungus infects tomato plants through the roots, colonizes
the vascular system, and eventually leads to wilting, yellowing, and plant
death (Agrios, 2005).
Conventional methods for controlling Fusarium wilt, such as
soil fumigation and the use of chemical fungicides, are often ineffective and
can have negative environmental impacts (Gullino et al., 2000). The development
of resistant tomato cultivars is an important strategy for managing Fusarium
wilt, but the emergence of new races of the pathogen can overcome resistance
genes (Foolad et al., 2008).
1. 2 Problem Statement
The increasing prevalence of Fusarium wilt and the
limitations of conventional control methods necessitate the development of
sustainable and environmentally friendly strategies for managing this disease.
Biological control, using beneficial microorganisms, offers a promising
alternative to chemical control (Whipps, 2001). Endophytic bacteria, which
colonize plant tissues internally without causing disease symptoms, have shown
potential for controlling various plant diseases, including Fusarium wilt (Compant
et al., 2005).
1. 3 Objectives
The objectives of this study were to:
1. Isolate and identify endophytic bacteria from tomato
plants.
2. Evaluate the *in vitro* and *in vivo* antifungal activity
of selected endophytic bacteria against *Fusarium oxysporum* f. sp.
*lycopersici*.
3. Investigate the
mechanisms of action of the most effective endophytic bacteria in suppressing
Fusarium wilt.
4. 4 Hypotheses
This study tested the following hypotheses:
1. Endophytic bacteria can be isolated from tomato plants.
2. Some endophytic bacteria possess antifungal activity
against *Fusarium oxysporum* f. sp. *lycopersici*.
3. Endophytic bacteria can suppress Fusarium wilt of tomato
under greenhouse conditions.
4. The mechanisms of action of endophytic bacteria in
suppressing Fusarium wilt involve the production of antifungal compounds and
the induction of systemic resistance in tomato plants.

2. 1 The Role of
Probiotics in Poultry Production
Probiotics are defined as live
microorganisms that, when administered in adequate amounts, confer a health
benefit on the host (FAO/WHO, 2001). The use of probiotics in poultry
production has gained increasing attention in recent years as a means to improve
gut health, enhance immunity, and improve overall performance (Patterson and
Burkholder, 2003; Mountzouris et al., 2007). This interest stems partly
from concerns about the use of antibiotic growth promoters (AGPs) in animal
feed and the potential for the development of antibiotic-resistant bacteria
(Dibner and Richards, 2005).
2. 1.1 Mechanisms
of Action of Probiotics
The beneficial
effects of probiotics in poultry are attributed to several mechanisms,
including:
- Competitive
Exclusion:
Probiotics compete with pathogenic bacteria for nutrients and attachment
sites in the gastrointestinal tract, thereby reducing the colonization of
pathogens (Nurmi and Rantala, 1973; Stavric and D'Aoust, 1993). This is
often cited as the primary mechanism.
- Production
of Antimicrobial Substances: Some probiotic strains produce substances that inhibit
the growth of pathogens, such as bacteriocins, organic acids (lactic acid,
acetic acid), and hydrogen peroxide (Rolfe, 2000; Teo and Tan, 2005).
- Stimulation
of the Immune System: Probiotics can modulate the host's immune response by increasing
the activity of immune cells, such as macrophages and natural killer
cells, and by enhancing the production of antibodies (Isolauri et al.,
2001; Schiffrin et al., 1995).
- Improvement
of Gut Morphology: Probiotics can improve the integrity of the intestinal lining by
increasing villus height and crypt depth, which enhances nutrient
absorption (Samanya and Yamauchi, 2002).
- Enzyme
Production:
Certain probiotics can enhance digestive processes by producing enzymes
like amylase, protease, and lipase, thereby improving the bird's ability
to utilize feed (Apata, 2008).
1.
1.2 Commonly Used Probiotic Strains
in Poultry
Several bacterial and yeast species are used as probiotics in
poultry, including:
- Lactobacillus species (L. acidophilus, L.
casei, L. plantarum)
- Bacillus species (B. subtilis, B.
licheniformis)
- Enterococcus species (E. faecium, E.
faecalis)
- Bifidobacterium species (B. bifidum, B.
longum)
- Saccharomyces
cerevisiae
(yeast)
1.
1.3 Effects of Probiotics on Poultry
Performance
Numerous studies have reported positive effects of probiotics
on various aspects of poultry performance, including:
- Improved
Growth Rate and Feed Conversion Ratio: Probiotics have been shown to improve weight
gain and feed efficiency in broilers and laying hens (Kabir et al.,
2004; Zhang et al., 2005).
- Reduced
Mortality:
Probiotics can reduce mortality rates, particularly in young chicks, by
protecting them against enteric pathogens (Jin et al., 1998).
- Enhanced
Egg Production and Quality: In laying hens, probiotics have been shown to increase
egg production, egg weight, and shell thickness (Yousefi and Karkoodi,
2007; Panda et al., 2008).
- Improved
Carcass Quality:
Probiotics can improve carcass yield and reduce abdominal fat deposition
in broilers (Mahdavi et al., 2005).

4. 1 Effect of
Different Starter Cultures on the Physicochemical Properties of Yogurt
Table 4.1 shows the
changes in pH, titratable acidity (TA), and syneresis of yogurt samples made
with different starter cultures during fermentation. The pH of all yogurt
samples decreased significantly (P ≤ 0.05) during fermentation, reaching values
between 4.2 and 4.5 after 6 hours. Yogurt made with starter culture A ( Lactobacillus
delbrueckii subsp. bulgaricus and Streptococcus thermophilus)
showed the fastest rate of pH decline, followed by culture B (Culture A + Bifidobacterium
lactis) and culture C (Culture A + Lactobacillus acidophilus).
The TA of all yogurt samples increased significantly (P ≤
0.05) during fermentation, reflecting the production of lactic acid by the
starter cultures. Yogurt made with culture A had the highest TA, followed by
culture B and culture C.
Syneresis, which is the separation of whey from the yogurt
gel, was significantly (P ≤ 0.05) lower in yogurt samples made with cultures B
and C compared to culture A. This indicates that the addition of Bifidobacterium
lactis or Lactobacillus acidophilus to the traditional yogurt
starter culture improved the water-holding capacity of the yogurt gel.

Different Starter Cultures on the Viability of Probiotic Bacteria
Figure 4.1 shows
the viable counts of Bifidobacterium lactis and Lactobacillus
acidophilus in yogurt samples made with cultures B and C, respectively,
during refrigerated storage for 28 days. The viable counts of both probiotic

5. 1 Effects of
Dietary Enzyme Supplementation on Broiler Performance
The results of this
study demonstrated that dietary supplementation with the multi-enzyme complex
significantly (P ≤ 0.05) improved body weight gain, feed intake, and feed
conversion ratio (FCR) in broiler chickens during the starter, grower, and
finisher phases. These findings are consistent with previous studies that have
reported positive effects of enzyme supplementation on broiler performance
(Cowieson et al., 2006; Adeola and Cowieson, 2011).
The improved performance observed in the enzyme-supplemented
groups can be attributed to several factors. First, the enzymes in the
multi-enzyme complex (xylanase, amylase, and protease) hydrolyze non-starch
polysaccharides (NSPs), starch, and protein, respectively, in the feed, making
these nutrients more available for digestion and absorption by the birds
(Bedford and Classen, 1992; Choct, 2006). NSPs, such as arabinoxylans and
β-glucans, are present in significant amounts in cereal grains, such as corn and
wheat, which are commonly used in broiler diets. These NSPs can increase the
viscosity of the digesta in the small intestine, reducing nutrient
digestibility and increasing the risk of enteric diseases (Choct, 1997). By
hydrolyzing NSPs, xylanase reduces digesta viscosity, improving nutrient
absorption and reducing the proliferation of pathogenic bacteria in the gut.
Second, enzyme supplementation can improve the utilization of
phytate-bound phosphorus. Phytate is the main storage form of phosphorus in
plant-based feed ingredients, but it is poorly utilized by poultry due to the
lack of endogenous phytase enzyme (Selle et al., 2000). The phytase
enzyme in the multi-enzyme complex hydrolyzes phytate, releasing phosphorus and
other minerals, such as calcium and zinc, making them available for absorption
(Ravindran et al., 1995). This can reduce the need for inorganic
phosphorus supplementation in the diet, which can be beneficial from both an
economic and environmental perspective.
5. 2 Effects of
Dietary Enzyme Supplementation on Nutrient Digestibility
The results of this
study also showed that dietary enzyme supplementation significantly (P ≤ 0.05)
improved the apparent ileal digestibility of dry matter, crude protein, and
phosphorus. These findings are in agreement with previous studies that have reported
improved nutrient digestibility with enzyme supplementation in broiler chickens
(Zanella et al., 1999; Amerah et al., 2009).
The improved nutrient digestibility observed in the
enzyme-supplemented groups is likely due to the direct effects of the enzymes
on the feed components, as discussed above. By breaking down complex
carbohydrates and proteins, the enzymes make these nutrients more accessible to
the digestive enzymes produced by the bird, leading to increased digestion and
absorption.

6. 1 Summary of
Findings
This study
investigated the efficacy of three different insecticides (imidacloprid,
abamectin, and spinosad) and a biological control agent (Bacillus
thuringiensis, Bt) for the control of the tomato leafminer, Tuta
absoluta, in a greenhouse tomato crop. The main findings of the study are:
- All
three insecticides significantly reduced T. absoluta larval
populations and leaf damage compared to the untreated control.
- Imidacloprid
provided the highest level of control, followed by abamectin and spinosad.
- Bt
was less effective than the chemical insecticides in reducing T.
absoluta populations, but it still provided a significant level of
control compared to the untreated control.
- No
phytotoxicity was observed in any of the treatments.
1.
2 Conclusions
Based on the results of this study, it can be concluded that
imidacloprid, abamectin, and spinosad are effective insecticides for the
control of T. absoluta in greenhouse tomato crops. However, the choice
of insecticide should be based on factors such as the level of infestation, the
cost of the insecticide, and the potential for resistance development. Bt can
be used as a biological control agent for T. absoluta, but it may be
less effective than chemical insecticides in situations with high pest
pressure.
6. 3
Recommendations
The following
recommendations are made based on the findings of this study:
- Regular
monitoring of T. absoluta populations is essential for timely
application of control measures.
- Imidacloprid
can be used for effective control of T. absoluta, but its use
should be rotated with other insecticides to prevent resistance
development.
- Abamectin
and spinosad can be used as alternatives to imidacloprid, particularly in
situations where resistance to neonicotinoid insecticides, such as
imidacloprid, is suspected.
- Bt
can be incorporated into an integrated pest management (IPM) program for T.
absoluta as a sustainable and environmentally friendly control option.
- Further
research is needed to determine the long effect and economic impact.
6.4 Future Research
- Further
research is needed to investigate the potential for resistance development
to the insecticides used in this study.
- Studies
should be conducted to evaluate the compatibility of Bt with other
biological control agents and natural enemies of T. absoluta.
- The
economic feasibility of using different control strategies for T.
absoluta should be assessed.
- Research
on the effect of different application timings is warrented.
