Bulletin – Mekong River delta, May 2017 Volume 10 Page 1
An Giang finished late Winter-Spring, Dong Thap started early Summer-Autumn
Field records by technical experts from Can Tho University from 30 Dec, 2016 to 30 Apr, 2017 show that
when most of Winter-Spring rice in 2017 in An Giang is in the tillering stage, farmers in its neighbourhood - Dong
Thap province, have started land prepration for Summer-Autumn crop 2017. As of mid-February 2017, the Summer-
Autumn rice in Dong Thap has been transplanted.

The season gap between the two Mekong Delta provinces is about one month. While Dong Thap is likely
following the region’s calendar, there is a lag with An Giang compared to the rest. The time-series statistical data over
last years has shown the Summer-Autumn season is from about mid-February to the end of June, similar to
observations recorded by RIICE project team in Dong Thap.
Most of the Winter-Spring 2016-2017 rice crop in Dong Thap was planted in October 2016, while in An
Giang it was around November. Farmers also follow a loose seasonal calendar, resulting in a large area of rice being
transplanted at different dates. The information extracted from the Sentinel-1A and 1B satellite from early October
2016 to the end of March 2017 clearly illustrates the situation of rice production in the two delta provinces.

The Winter-Spring rice cultivated area in An Giang and Dong Thap provinces was estimatedly 227,461 ha
(An Giang) and 203,476 ha (Dong Thap). Compared to the report on agricultural production in the whole region of
MARD (April 2017), the area of rice tracking from satellite images shows a difference of 5% for An Giang and 3%
for Dong Thap.
On the harvested Winter-Spring rice fields, farmers have plowed the land for the Summer-Autumn crop.
According to the monthly report from the Ministry of Agriculture and Rural Development (Report on agricultural
production in the whole country, April, 2017), the Summer-Autumn rice transplanting progress is slower than the
same period last year due to the delay of the foregoing Winter-Spring crop (nearly a month). An Giang province is
one of the provinces where the Summer-Autumn crop started later for the mentioned reason.

As usual, the monitoring of rice production in the Mekong Delta was carried out by the RIICE project team
at the beginning of the season. With 18 Sentinel-1 satellite images, collected from the beginning of October 2016 to
the end of April 2017, the map of Winter-Spring 2017 crop extent was compiled for An Giang and Dong Thap
provinces.

RIICE has been carrying out end-of-season crop yield analyzes for Dong Thap and An Giang at different
times, in accordance with planting progress and regional weather conditions. The appropriate time to forecast
productivity for An Giang is around early April 2017, while the end of February 2017 is a right time for Dong Thap.
The analysis of the Oryza yield model shows a yield decline in Dong Thap compared to the same period last year. The
shortfall is 560 kg/ha or 9 percent. In An Giang, however, the yield increases 6%, reaching to 7.5 tons/ha.
Provincial, district and commune data of An Giang and Dong Thap provinces in the Winter-Spring 2017 are
presented in the tables below.
