<div>Field experiment was conducted to evaluate the growth, yield and essential oil constituents of savory at three different locations across Egypt (El-Minya, El-Sharkia and Sinai). Plants cultivated in El-Sharkia showed significantly higher values of plant height, number of branches and herb fresh and dry weights. Also, the highest quality was observed on plant cultivated in El-Sharkia region. Thirty one main compounds were detected in GC-MS analysis of essential oil. There were obvious differences in chemical constituents of essential oil of plants cultivated under different locations. The main components were &atilde;-Terpinene and Carvacrol. The highest &atilde;-Terpinene and Carvacrol were observed also in plants cultivated in El-Sharkia. These results suggested that agro-climatic zone is very important for maximizing the content and composition of essential oils.Further studies are still needed to determine the precise factors of agro-climatic zoning which could be important strategies for optimizing the yield and quality.</div>

<div><strong>Background: </strong>Lettuce (<em>Lactuca sativa</em> L.) is an annual plant with very rapid growth and a major species in the assortment of leafy vegetables. Plant parasitic nematodes are economically important pests of leafy vegetables in monoculture and intensive organic fertilization. The simultaneous cultivation of several plant species in the same area can overcome the disadvantages of crops from homogeneous crops. The purpose of this work is to determine the quantitative changes in soil nematode communities in the joint cultivation of medicinal and vegetable species.&nbsp;<br />
<br />
<strong>Methods:</strong> The experiments were carried out in a vegetation house. To create mixed crops, the plants the lettuce (<em>Lactuca sativa</em> L.), cutivar &lsquo;Bohemia&rsquo;, tagetes (<em>Tagetes </em>sp. L.), basil (<em>Ocimum basilicum</em> L.), calendula (<em>Calendula officinalis </em>L.) summer savory (<em>Satureja hortensis </em>L.) and arugula (<em>Eruca sativa</em> L. Cav.) were used.&nbsp;<br />
<br />
<strong>Result: </strong>The results of the nematological analysis showed a decrease in the number of nematodes when mixed growing of lettuce with arugula, calendula and tagetes. The mixed growing of lettuce and calendula resulted in a significant reduction in nematodes, with a Pf/Pi value of 0.3. As a result of the decrease in the nematode population, there was an increase in lettuce yields when mixed grown with arugula and calendula, compared to when grown alone. The study of plant parasitic nematodes based on comparative evaluation of different combinations of plants shows that combinations of crops can be applied as a control method in integrated plant protection systems.</div>
