Understanding the interactions among soil properties,

salinity and the inorganic substances application is

great importance for improving growth of Coriander [Coriandrum sativum L.] in sandy soils. In the present

study, twenty seeds of Coriander were sown during the growing season 2016 to investigate the effe ct of some

inorganic substances [Bentonite, Nano selenium and Micronutrients mixture] on Coriander growth and

properties of sandy soil under salinity condition. A split plot design replicated thrice was used in this study.

The results indicated significa nt succeed in enhancing all estimated soil properties, such as available

nutrients in soil, EC, pH and bulk density. Besides, traits of coriander plant i.e., plant height, fresh, dry weights

and plant chemical composition. Therefore, it could be recommende d that adding of inorganic substances can

improve the sandy soil properties and growth parameters of coriander plant

Factorial field experiment was conducted to evaluate relationship between two genotypes of local wheat (Triticum aestivum) and phosphorus soil test values. The M 0.5 NaHCO₃ based (Olsen phosphorus) extractant was carried out on soils taken from the plots. The experiment was conducted at western region of Libya. Soil pH at the experimental site was 8.1 and the texture is sandy. The experiment was performed using a randomized complete block design (RCBD) method with three replicates for each treatment of phosphate fertilizer at concentrations of 0, 60, and 120 kg P₂O₅ ha^-1 for both genotypes. Results were expressed by relative values (Relative Yield). Relative yield (RY) of the two wheat cultivars showed similar significant responses to both soil test values and the grain yield. Linear relationship between relative yield and the grain yield at 0 kg P2O5 ha^-1 for both genotypes was found, whereas, non-linear relationship was noticed among treatments that received 120 kg P₂O₅ ha^-1. Both the linear and non- linear relationship have explained by tendency curves and showed how both genotypes response to phosphate fertilizer.

Field experiment was conducted to evaluate the correlation relationship between the yield of two localized wheat genotypes (Triticum aestivum,) Acsad 901 and Salamboo and Olsen phosphorus soil test (0.5 M of NaHCO3 at pH 8.5) values. The experimental site was run at west sector of Libya. The experimental site pH was 8.4 and the texture is sandy The experiment consisted of three replicates and three phosphate fertilizer rates which equivalent, (0, 60, and 120) kg P2O5 ha-1 for both genotypes. The results of grain yield of the experiment were expressed by relative values (Relative Yield). The relative yield (RY) illustrated the relationship between soil test values and the grain yield clearly. Very close correlation relationship (r = 0.98 ) between relative yield of grain and the soil test values of Salamboo was found whereas Acsad genotypes was achieved less correlation( r =0.69) at 0 kg P2O5 ha-1 for both genotypes. The similarity between the two genotypes was very close (r = 0.99 ) for treatments that received high phosphate rate.

A strengths, weaknesses, opportunities, and threats (SWOT) analysis has become a key tool used

by businesses for strategic planning. Scholars have conducted SWOT research for over six

decades. However, a collective understanding of SWOT analysis remains vague. This study

accessed, analyzed, and synthesized the SWOT literature, allowing for new theoretical

perspectives and frameworks to emerge. Using an integrative literature review, this study reviewed

SWOT studies historically, providing a greater understanding of the SWOT analysis in different

sectors and the different approaches used in SWOT studies. Furthermore, it fills the knowledge

gap in the strategic planning context and indicates meaningful implications for managers that could

help improve their strategic decisions.

Contamination of wastewater by toxic metals is a global environmental concern. In this study, the possibility of using inactive (dead) Sargassum bacilluria powder as a natural adsorbent was investigated in the removal of cadmium from aqueous solutions. The biosorption process was found to be highly dependent on a set of variables such as pH, temperature, contact time, shaking speed and initial metal concentration. The results showed an optimum pH value, (6.0) for cadmium, where was the biosorption capacity (842.15±0.252) for cadmium, and the lowest biosorption value for Cd was found at pH 2.0. The optimum temperature in this study was 30 °C. The time required for equilibrium was investigated over a period of 360 min and found to be 180 min. The capacity of biosorption increased with increasing shaking speed, and the highest uptake value was found at 120 rpm. The maximum removal of Cd+2 was found at 20 mg/l. The models Freundlich and Langmuir were used to study the equilibrium process of these systems. The Langmuir model was found to be more suitable for the interpretation of these systems by the value of the correlation coefficients higher than 0.99. Brown seaweed powder is an effective, low-cost, .and environmentally friendly adsorbent for removing metals from aqueous solutions, according to the results obtained.

Factorial field experiment was done to estimate agronomic phosphorus use efficiency (APE) and partial factor productivity (PFP). The experiment was run in a private farm in Janzour area which is located west of Tripoli Libya in 2018. Two localized wheat genotypes (L1, and L2) and three rates of triple super phosphate fertilizer (0, 60, and 120) kg P2O5 ha-1 were used. The results indicated that both genotypes have good response to phosphate fertilization. APE and PFP achieved positive relationship with only 60 kg P2O5 ha-1 rate for both genotypes. Moreover, APE calculation showed positive relationship with increasing soil phosphorus test values, meanwhile, APE values was kept steady at 120 kg P2O5 ha-1 .
