Citizen Succeeds in Increasing Cucumber Production


The farmer, Salem Al-Essayi, in the state of Saham, was able to implement a system of cooling the nutrient solution in hydroponics in greenhouses for the production of cucumber crop hydroponics.

Al-Eisayi explained that the amount of production before the cooling system ranges from 4 to 5 tons, and after using the cooling system, it ranges from 5 tons and a half tons to 6 tons.

Dr. Moathir bin Saleh Al Rawahi, Head of the Vegetable Research Department said: Efforts are continuing by researchers in the Vegetable Research Department of the General Directorate of Agricultural Research at the Ministry of Agricultural, Fisheries and Water Resources to develop soilless farming techniques in the Sultanate, as the technology for cooling the nutrient solution was developed during the summer period. This technique was applied to the cucumber crop.

He added that one of the most important reasons that led to the development of this technology is the noticeable rise in temperatures during the summer season, which in turn leads to an increase in the temperature of the nutrient solution, reaching between 32 - 35 degrees Celsius, which directly affects the plant as the absorption of nutrients decreases. By the roots of the plant, thus weakening it and causing a decrease in its productivity, in addition to infecting the root system with fungal diseases, which was a greater obstacle for many farmers who applied this system.

He mentioned the example of "a rise in the temperature of the root zone of the cucumber crop to more than 30 degrees Celsius that affects most of the physical, chemical and biological processes that the plant performs and becomes unable to absorb water and nutrients in a good and usual way, which stops its growth and becomes weak in structure and cannot resist." Diseases and may lead to its death often, so cooling the root zone is very important, as the amount of chlorophyll formed in plants is strongly influenced by environmental factors, including temperature changes, because optimum temperatures enhance the increase in carbohydrates and photosynthesis processes, which leads to Increased chlorophyll in leaves and positively affects productivity.

He explained that the temperature of the water or the nutrient solution is an important factor affecting plant development in water systems, so it is necessary to study the optimum temperature requirements for different crops grown in high-temperature conditions (summer).
