The multicolored picture of the rice fields in An Giang and Dong Thap shows a wide variation in the start of the season dates (SoS) and also reflects technical challenges in monitoring rice production across the Mekong Delta.

The majority of early winter-spring rice in Dong Thap has been harvested (over 50% of the total area). On these fields, farmers have not yet done land preparation. Rice residuals have begun to regrow. Besides, the rest of the late winter-spring rice is in the ripening stage, preparing to harvest. In parallel with An Giang, a small area in Dong Thap is in the progress of tillering or booting.

In An Giang, SoS variations remain smaller amplitudes. Most An Giang rice is at the end of the tillering, milking and maturity stages. A small area of An Giang is in the final stage of the maturity period, which is expected to be harvested in two weeks.

With sunny weather, regular irrigated condition, average water level in the field 3-10cm, the Winter-Spring 2017 season in An Giang and Dong Thap will give farmers a promising harvest.

Field work has been conducted regularly on 25/9, 7/10, 19/10, 31/10, 12/11, 24/11, 6/12, 18/12, 30/12 2016; 11/1, 23/1, 4/2, 16/2 and 28/2 2017. Field survey records, combined with statistics from the Ministry of Agriculture and Rural Development and the General Statistics Office are important inputs that contribute to improving the accuracy of satellite image interpretation and rice yield forecast model.

According to Can Tho University's technical experts, about 50% of the project sites were planted with sticky rice (Thai sticky rice and CK variety). Therefore, Spring 2017 may likely be longer than normal due to the longer glutinous rice growing charecteristics. From the middle until the end of April 2017, all winter-spring rice in An Giang and Dong Thap provinces will be harvested.

RIICE has been carrying out end-of-season yield forecasts for Dong Thap, as well as making preparations for An Giang later. The results of the analysis on the Oryza yield model show a decrease of 5.6 quintals per hectare in yield of Dong Thap compared with the same period last year was.
