Authorities have instructed farmers in the Mekong Delta to sow the summer – autumn rice crop on established schedules to mitigate the damage of drought, saltwater intrusion and disease.

The delta, the country’s rice granary, plans to grow about 1.6 million hectares of rice in the summer – autumn crop, according to the Ministry of Agriculture and Rural Development’s Plant Cultivation Department.
The delta is facing drought and severe saltwater intrusion which is expected to continue and only reduce after this month.
The Plant Cultivation Department has set schedules for sowing the crop in the delta between March and June.
In areas that can secure irrigation water, the sowing is in March and April, while sowing is set in May for areas located south of National Highway No 1 and 70km from the coast.
In areas that depend on rainwater for irrigation, sowing will be in the first half of June when rain is expected.
Based on the sowing schedules, the delta’s 12 provinces and Can Tho City have set up detailed sowing plans for each area.
In Kien Giang Province, which is the delta’s largest rice producer, the province’s Department of Agriculture and Rural Development has given farmers detailed plans between March 20 and June 26.
The level of water resources in Kien Giang’s upper areas has been low, so the province has operated sluices properly to prevent shortage of irrigation water and has dredged irrigation ditches to increase water storage.
Kien Giang targets growing 284,000ha of rice with an average yield of 5.5 tonnes per hectare in the summer – autumn crop.
The province has instructed farmers to grow more high-quality rice varieties that meet export standards, aiming for 85 per cent.
In An Giang Province, farmers have been told to sow the crop between March 10 and May 20 to avoid irrigation water shortage and pests, mostly brown plant hoppers.
Nguyen Si Lam, director of the An Giang Department of Agriculture and Rural Development, said farmers should follow schedules to avoid damage caused by brown plant hoppers.
Farmers should also apply integrated pest management and other techniques used in rice cultivation, he said.
In Soc Trang Province, authorities have told farmers to sow the crop between the end of April and June, and each area has to sow rice seeds at the same time to prevent the spread of brown plant hoppers.
Ngo Thanh Loan, deputy head of the Soc Trang Plant Cultivation and Protection Sub-department’s Plant Cultivation Division, said: “In areas affected by saltwater intrusion, farmers have to wash salts out of fields carefully before sowing rice seeds.”
When the price of rice rose recently, many farmers in the delta sowed the summer – autumn rice crop earlier compared to instructed schedules after they had a bumper harvest for the 2019-20 winter – spring rice crop.
Farmers had a bumper harvest because local authorities had instructed farmers to grow the crop one month earlier compared to normal schedules to avoid the impact of drought and saltwater intrusion.
However, the delta saw 33,800ha of its 1.54 million hectares of winter – spring crop damaged by drought and saltwater intrusion as many farmers did not follow the sowing schedule instructions. — VNS
Despite being affected by drought and saltwater intrusion, the Mekong Delta harvested a record output of about 7.3 million tons of rice in the Winter-Spring crop 2019-2020.
Though saltwater intrusion in the Mekong Delta comes earlier and with higher level of salinity than that recorded in the 2015-16 dry season, the damages to farming areas are expected to be less serious
The Mekong Delta plans to grow this year’s winter – spring rice crop early since drought and saltwater intrusion are forecast to be severe in the dry season starting at the end of this year.
