Basra grows date palms at a lab due to rising salinity levels and heat.

Iraqi technicians in masks and gloves lift tiny?date-palm shoots out of jars. They hope to one day restore orchards that have been ravaged by wars, land loss, and the creeping salinity of?water.

The date palms that were once the backbone of Iraq's agriculture have been decimated by the damming upstream of?the?Tigris?and?Euphrates?, decreasing rainfall, seawater invasion and decades of war.

Scientists and government officials are stepping up their tissue-culture propagation efforts to create disease-free date-palm saplings, and preserve rare Iraqi types.

Mohammed Abdulrazzaq is the director of Nakheel Al Basra. He said that tissue-culture agriculture was distinguished by its high productivity. In the past, a palm could produce three or four offshoots. With tissue culture, however, we can create thousands.

ONE PALM CAN GENERATE THOUSANDS OF OTHERS

Nakheel Al Basra is one of the largest tissue-culture laboratories in the province. It began operating in 2023, and it can produce 250,000 palm seedlings per year.

Workers in the laboratory use gloves and masks to prevent contamination when handling palm samples. The smallest shoots are placed in jars, and then moved through a series of stages to create uniform, disease-free plant?material.

Abdulrazzaq claimed that wars, the destruction of farmland, and increasing salinity of water had "pushed" some Iraqi dates to the verge of extinction.

Iraq's water supply has become an urgent issue, as the Euphrates River and Tigris River have fallen sharply. This is compounded by dams upstream, mostly in Turkey.

The drop in Shatt al-Arab has allowed the seawater to move further inland. This has increased salinity levels to unprecedented levels. Farmers describe this as a "saline advancing tongue" that is affecting their water supply.

Basra once had 32 million palm trees in total, according to Dr. Jassim Mohammad, the head of the agriculture division at Basra Directorate of Agriculture. However, the number of palm trees has dropped sharply since then.

Toughened to withstand heat and salt

The researchers at the facility said that producing seedlings was only part of the problem in Basra where temperatures in the summer can reach 50 degrees Celsius and the salt content in the water can rise.

Ismail Sadiq is a researcher at Nakheel al Basra and said that to improve survival rates young palms must be acclimated to extreme conditions by raising the temperature gradually before planting.

He said that the process begins at 25C and increases to 52C in the summer.

"This means that when the palm is moved to a place with temperatures similar to or higher than those in its current location, it will be fully acclimated," Sadiq explained.

He said that salt concentrations in the lab are also gradually increased, from zero to between 6,000 and 8,000 parts per millions (ppm) to prepare plants for saline water on the field.

Abdulrazzaq, standing in a greenhouse with rows of young palms lined up and irrigation lines running through it, said that the process was now at its post-lab phase.

He said that the palms were ready for farmers to buy and needed six months to be planted. "They're ready for outdoor conditions."

Farmers claim that the technique has already improved survival rates. Faysal al-Khazraji, a farmer from Kuwait, said that he had planted 100 tissue-culture seedlings along with 100 conventional offshoots.

He said, "100 of the tissue culture palms were successful while we got only 25 out of 100."

Abdulrazzaq stated that the laboratory propagates Iraqi varieties, including Barhi. It also introduces commercial types imported from abroad such as Sukkary. He added that seedlings up to 30 cm tall are sold locally for $40-$60.

Saleh Hassan said that tissue-cultured palms represent more than 15 percent of the varieties in Basra’s Al-Zubair, and Safwan districts.

Basra added approximately 600,000 palms in the last five years. This brings the total up to about three million palms, according to Dr. Mohammed. He said that tissue-cultured Palms account for over 100,000 of these. (Writing and editing by Enas Alashray)
