CAN THO: Using organic fertilizer from rice straw to fertilize rice has helped reduce the cost of fertilizers and chemical drugs by 35-40%; profits increased by 10%.
On May 18, the Can Tho Plantation and Plant Protection Sub-Department in collaboration with the International Rice Research Institute (IRRI) held a field workshop on “Rice farming model using organic fertilizer from straw”.
The model was deployed in the summer-autumn rice crop 2023 at Mr. Tran Van Dao’s household in Tan Hung ward, Thot Not district (Can Tho city) with an area of 1.7ha, of which 1ha was built to build a model using fertilizers. organic fertilizer from rice straw and the remaining area (7 workers) as a control was cultivated according to traditional methods, using 100% chemical fertilizers and pesticides.

Mr. Tran Van Dao said, this year’s summer-autumn rice crop, the model field of organic rice farming uses 1 ton of straw fertilizer to fertilize 1 hectare of rice, divided into several times during the crop. Besides, there is a small amount of NPK fertilizer sponsored by Phu My Fertilizer Company to ensure enough nutrients for the green growth of rice plants.
In this rice crop, Mr. Dao cultivates OM5451 variety, sowing seeds with an amount of 80kg/ha. Currently, his family’s rice is about to be harvested. According to the preliminary assessment results of the professional industry, the yield of fresh rice in the model field is estimated at 6.4 tons/ha, 0.3 higher than the control field. tons/ha.
According to Mr. Dao, currently 1ha of organic rice cultivated by the family has about 1 week left to harvest, traders have come to the house to pay a deposit in advance to buy at the price of 6,300 VND/kg, after deducting everything. expenses, he also made a profit of more than 3 million dong/work.
Ms. Pham Thi Minh Hieu, Head of Can Tho City’s Plantation and Plant Protection Sub-Department, said that the model field using organic fertilizer composted from straw (1 ton/ha) helps the rice plant’s roots grow larger and longer than that of rice straw. with farmers’ unfertilized fields. The roots are much and deeply rooted to help the rice plant to be strong, limit falling, post-harvest losses…

Rice production follows the model of using certified seed or higher, sowing density is sparse (80kg/ha), priming with organic fertilizer at the beginning of the crop to help reduce nitrogenous fertilizers, limit the possibility of generation and cause damage. pests and diseases, thereby reducing the amount of pesticides, helping to reduce production costs, increase productivity, increase profits and rice grain quality.
According to the Director of the Can Tho Plantation and Plant Protection Sub-Department, the city’s agricultural sector is currently implementing pilot models of rice cultivation using organic fertilizers from rice straw combined with technical advances. “1 must 5 decrease” in districts such as Thoi Lai, Co Do and Thot Not district…, each model has been demonstrated 1ha and has done 2 rice crops with 6 models deployed (winter-spring crop and summer-autumn crop). in 2023).
Through the evaluation results, the model helps farmers reduce the cost of using fertilizers and chemical drugs by 35 – 40% and increase profits by 10% on the same area compared to traditional production.
“The solution of organic rice farming with organic fertilizers made from rice straw has helped farmers reduce production costs significantly. In the coming time, the agricultural sector of Can Tho recommends that this model should be replicated so that more farmers know and apply it,” said Ms. .
Ms. Dinh Thi Kim Dung, Chief of Office of the International Rice Research Institute (IRRI) in Vietnam, said that from 2022, IRRI in collaboration with the Sub-Department of Crop Production and Plant Protection of Can Tho City has supported training for farmers. People in Thot Not district about the technique of making use of rice straw, turning it into organic fertilizer for rice.

“This time we came back here and saw that farmers use organic fertilizer from rice straw to fertilize rice to help rice grow green, less pests and higher productivity. It can be said that this is a circular agricultural model. , helps reduce greenhouse gas emissions, is environmentally friendly and adapts to climate change to minimize production costs, produce safe and quality products.
