Pistachio trees consume nutrients from the soil, especially when they produce high yields. Therefore, do not hesitate to apply the appropriate fertilizers in quantities suitable for the production that you aspire to reach and advertise. Moreover, poor fertilization results in a lack of production, small size of nuts, and alternate fruit bearing. Trees may stop bearing permanently in poor soils and when nutrients are depleted from the soil after long periods of non-fertilization.

Diseases affecting tomatoes in greenhouses have changed over the past years. Up until 2015, nematodes and TYLCV were the main concern of farmers, yet Fusarium became the most widespread and harmful disease and the first concern for farmers, merchants and agricultural companies. Fusarium is the species that determines the spreadable varieties, as well as the required grafting rootstocks in nurseries and even pesticides and fertilizers. The main problem with the disease is that it kills the entire plant, thus “zero” production is obtained.

Biostimulants are a group of natural organic compounds that are added to the soil in order to enhance nutrient uptake and activate the role of fertilizers. They are also added with fertilizers and foliar pesticides for the same purpose and to resist factors of plant stress. Despite the rapid growth of the biostimulants market, many professionals and farmers still lack a comprehensive understanding of biostimulants, how they are used, their benefits, and their dangers.

Melon (Canary melon), scientifically known as Cucumis melo, (this name will be used in this study) is one of the crops that evolve and propagate over the years on coastal greenhouses, due to its good profitability during a short season and low costs. This product is sold at reasonable prices at times when it is not found on the market.

The potato (Solanum tuberosum L.) is an annual and dicotyledonous plant from the family of Solanaceae with 26 genus and 2800 species. Cultivative potatoes belong to S. tuberosum with 180 varieties that produce tubers. Most commercial varieties of S. tuberosum are tetraploid. There are two subspecies: tubersum and andigena, whereas, tubersum is with world distribution expended. The root system of S. tuberosum is relatively weak and expands easily in light soil with sandy clay texture. Methods of propagation of potato are asexual with tubers division, and sexual with true potato seed culture.

Protected agriculture is the main source of livelihood for about 80% of the coastal farmers. This farming method has been introduced since the seventies of the last century, and the number of greenhouses has since been increasingly developed to meet the market needs.
