This study examined the effects of a commercial Lactobacillus probiotic on growth, survival and resistance of western white shrimp (Litopenaeus vannamei) larvae against salinity and formalin stresses in Persian gulf and Oman sea ecology research center. In this experiment, larvae were fed on 6 times a day from mysis I (M1) step to post larvae 5 over 3 treatments with 3 repetitions including a c...

plants growth in many parts of the world are influenced by biotic and abiotic environmental stresses. agriculture in these area is done with higher costs and lower efficiency. therefore, assessment of plant species is so necessary in terms of salt tolerance prior to planting in large-scale for development. in this regard, salinity stress on germination of sorghum bicolor was carried out in a co...

Due to the growing population, crop production is one of the essential needs of the society. Since soil and water salinity can have a great impact on the crop yield loss; so, the appropriate irrigation method can be applied to reduce these effects. In this study, the system dynamics model was developed using VENSIM. The model simulated the effect of salinity and water stress on the crop yield, ...

The effect of salinity and nitrogen on yield, vitamin C, citric acid and nutrient distribution of tomato in hydroponics culture was investigated. Tomato seeds were first let germinate in yonolit pots with wet coco peat and then their seedlings were transferred to plastic tanks containing 5 liters nutrient solution. Treatments were three levels of salinity (0, 30 and 60 mM as NaCl and CaCl2) and...

Improving soil microbial activity and using symbiosis and synergistic relations between plant growth-promoting rhizobacteria (PGPR), arbuscular mycorrhizal fungi (AMF) and plants through improving nutrient uptake can cause better growth of plants especially at salinity tension condition. To investigate the effect of AMF and PGPR application on growth and some nutrient uptake by corn in differen...
