Article Synopsis
  • * In a study involving 12,653 slaughtered sheep in Jeddah, Saudi Arabia, researchers amplified and sequenced the ITS-1 region of Fasciola adult worms, discovering 12 different DNA variants with a high similarity to sequences from other countries.
  • * The research concluded that the only Fasciola species found in the sheep studied was specific to Jeddah, indicating the need for further research across Saudi Arabia for better disease management.

The effect of foliar treatment with jasmonic acid at 0.5 mM (JA) and biochar (15 ton ha) as a soil amendment for the faba bean (Vicia faba L. Sakha 4) was studied under salinity conditions.

Drought stress deleteriously affects growth, development and productivity in plants. So, we examined the silicon effect (2 mmol) and proline (10 mmol) individually or the combination (Si + proline) in alleviating the harmful effect of drought on total phenolic compounds, reactive oxygen species (ROS), chlorophyll concentration and antioxidant enzymes as well as yield parameters of drought-stressed sugar beet plants during 2018/2019 and 2019/2020 seasons. Our findings indicated that the root diameter and length (cm), root and shoot fresh weights (g plant) as well as root and sugar yield significantly decreased in sugar beet plants under drought.

Broomrape parasitism on faba bean ( L.) is the most destructive factor for this crop in Egypt. Pot experiments were conducted during the two successive seasons 2017/2018 and 2018/2019 to study the mitigation of broomrape stress on faba bean using a ten-fold dilution of 10% (w/v) spent mushroom substrate extract (SMSE) of and the same dilution of culture filtrate of mushroom (MCF) grown in potato dextrose broth (PDB) at a rate of 48 l hectare compared with the commercial herbicide Roundup (Glyphosate 48% emulsifiable concentrate) at a rate of 144 cm ha on the two varieties (Misr3 and Sakha3) cultivated in broomrape-infested soil.

Silicon is one of the most significant elements in plants under abiotic stress, so we investigated the role of silicon in alleviation of the detrimental effects of salinity at two concentrations (1500 and 3000 ppm sodium chloride) in sweet pepper plants in two seasons (2018 and 2019). Our results indicated that relative water content, concentrations of chlorophyll a and b, nitrogen, phosphorus and potassium contents, number of fruits plant, fruit fresh weight plant (g) and fruit yield (ton hectare) significantly decreased in salt-stressed sweet pepper plants as compared to control plants. In addition, electrolyte leakage, proline, lipid peroxidation, superoxide (O) and hydrogen peroxide (HO) levels, soluble sugars, sucrose, and starch content as well as sodium content significantly increased under salinity conditions.

Chilling, a sort of cold stress, is a typical abiotic ecological stress that impacts the development as well as the growth of crops. The present study was carried to investigate the role of ascorbic acid root priming in enhancing tolerance of tomato seedlings against acute chilling stress. The treatments included untreated control, ascorbic acid-treated plants (AsA; 0.

Water deficit stress is an abiotic stress that causes reductions in growth and yield of many field crops around the world. The present research was aimed to elucidate the mitigating efficiency of exogenous application of select osmoregulators and biostimulants, i.e.
