Eel farming according to new model. (Photo: Anh Tuyet/VNA) Farmers in Can Tho city are very excited because intensive farming of field eels using water circulation technology has helped them stabilize their livelihoods and get rich with typical products. This is a research achievement that has been implemented into reality by scientists of the Can Tho University . Associate Professor, Dr. Pham Thanh Liem, Head of the Department of Freshwater Aquaculture Technology, Can Tho University, Head of the project, shared from the fact that eel farming households in Can Tho are implementing two projects. farming, with soil and without soil with plant media or bamboo/nylon blisters all have limitations. Because, for the farming model with land, the stocking stock is large in size, often using natural seed, the food used is trash fish or homemade food, low density, eels hiding in the mud become a hindrance in the management of feed and health of farmed eels. In landless farming model , if it is an eel obtained from the wild, the growth and yield are lower than the land culture model. The rate of water change in both farming methods ranges from 1-1.3 times/day with 100% fresh water. Both of the above methods give low eel farming productivity of less than 10kg/m2. If the stocking density is increased, the water exchange rate will increase and increase the risk of disease, environmental pollution and food safety. Since 2018, the research team has implemented the intensive farming model field eels by water circulation technology. This is a model that meets food safety and traceability requirements, while maintaining environmental quality and protecting natural resources. The strength of the model is the application of technical and biological solutions, self-cleaning and reuse of water sources, increasing the maximum eel farming density up to 600 fish/m2 and increasing productivity to 25kg. commercial eel/m2. The productivity of farmed eel also increased from 2.5-4 times compared with conventional farming model; profit efficiency is from 36.5-60.2%. Households raising eel under the new model ensure safe operation, control of pathogens, health and quality of farmed eel products; minimize the rate of water change, increase the output of cultured eel; improve and increase the growth rate, eel quality and production efficiency; allows the treatment of contaminated water and helps control the discharge process. Thereby, contributing to environmental protection; forming and developing farming technology to create clean, high-quality products, meeting the needs of consumers. Currently, the model is starting to be transferred and deployed in a number of breeding and commercial eel farming sites in Can Tho city. Mr. Nguyen Thanh Tan, owner of Binh Thuy farm, Long Tuyen ward, Binh Thuy district has implemented the eel farming model in the form of water circulation since 2019, on a test area of ​​30m2, including 5 tanks, each tank is 6m2. The culture tank is designed to connect to the water circulation system including a biological filter tank, a solid waste settling tank and a water tank. The flow of water through the aquarium is adjusted from 0.5-0.8 liters/min. Black nylon rope is tied into a beam with a length of 20-30 cm, used for sheltering eels. This cord is cleaned daily and renewed once a month. Model of an eel tank based on water circulation technology. (Photo: Anh Tuyet/VNA) Eels are incubated for 90 days, size from 1.4-3.2g/head. Eel feed is industrial pellets, with 41% protein content. Instead of having to change the water every day like the old model, in the water recirculation model, the water is changed every 2-3 weeks. This helps farmers reduce labor costs, water costs, as well as help stabilize the water quality of the aquarium, and the eels are healthier and faster. After 8-9 months, commercial eels can reach 400g / head, farmers’ profits doubled compared to the old model. “In the commercial eel farming group of Binh Thuy district, there are currently more than 10 households out of 40 members who have switched to raising eels using water circulation technology. In general, the model is quite easy to install, the initial cost is The income is not high. The members are aware of supporting each other in farming techniques as well as product output. Therefore, most of the farming households give quite positive feedback,” said Mr. Tan. According to Associate Professor, Dr. Pham Thanh Liem, in the near future, the model will be replicated in Ninh Kieu and Phong Dien districts. The purpose is to support farmers to increase the technology content in farming and farming.

Experiencing 3 production crops from the 2019 – 2020 winter-spring crop up to now, it shows that the synchronous application of scientific and technological measures and mechanization in peanut production in Tinh Tho commune has contributed to improve peanut yield, bring higher economic efficiency compared to rice and cash crops in the locality. New peanut varieties combined with intensive farming for high yield in Tinh Tho commune (Son Tinh, Quang Ngai). Photo: Thu Phuong. Tinh Tho commune is located in the northwest of Son Tinh district, the soil quality in the commune is relatively good, very suitable for the production of crops such as rice, corn, cassava, sweet potatoes, legumes of all kinds. In which, peanut is a crop that occupies a fairly large area with about 136 hectares, but the yield is still not commensurate with the potential. With the support of the provincial Department of Science and Technology, for the past 2 years, Tinh Tho commune has implemented an inefficient model of peanut cultivation on rice and cropland with an area of ​​80 hectares. In which, in the winter-spring crop 2020-2021, the commune planted 40 hectares, with 339 households in Tho Trung, Tho Nam and Tho Tay villages participating. The objective of the project is to apply synchronously scientific-technological measures and mechanization in peanut production to grow groundnuts on rice land and inefficient crops. The peanut varieties included in the demonstration included LDH.01, LDH.09 and L14. These are peanut varieties selected by the Institute of Agricultural Science and Technology of the South Central Coast, belonging to the good variety, creating a premise for high yield. Peanut varieties have wide adaptability, high yield in ecological regions, large fruit, shallow waist and veins, high seed rate. The variety is tolerant to drought conditions. During the production process, farmers were trained and guided in technical processes of peanut intensive cultivation on rice and inefficient crops such as preparing peanut varieties, handling seeds before sowing, selecting groundnut planting techniques, soil preparation, fertilization techniques, care when sowing and pest control. Accordingly, after the variety is selected, farmers dry the seeds to ensure that the water content in the seeds is less than 8%, classify large and small seeds to plant each bed separately for even plants. People make the soil according to the right techniques such as the soil is airy, porous, moist enough, weed free, the bed surface is flattened. Peanuts are planted in rows 25 cm apart, trees 10 cm apart, 1 seed/hole, density 40 plants/m2. Fertilizers to be applied include organic fertilizers, nitrogen, phosphorus, potassium and powdered lime. The 4-step application process includes priming, the first application after sowing 10-15 days, the second application after sowing 25-30 days, the third application, when the flower ends. In the process of development, the appearance of pests and diseases is also timely prevented. Groundnut is a very suitable crop for arid sandy soils, difficult to irrigate in Quang Ngai. Photo: Thu Phuong. In the bamboo field, Tinh Tho commune (Son Tinh district), Mr. Nguyen Tam, a farmer participating in the model said that in this crop, he planted 3 peanuts of L14 variety. Thanks to the guidance and methodical application of science and technology, the L14 peanut variety is highly resistant to disease, yielding about 3 quintals / sao (higher than the previous peanut variety, only about 2.6 quintals / sao). And Mr. Nguyen Xuan Son in the same commune also happily said that this crop he was supported to plant 2 sao L14 peanuts, this variety has wide adaptability, large fruit, high seed rate. Thanks to the correct application of the technical process, with 2 peanuts of L14 after harvesting, he is expected to press 75 liters of oil, 12 liters more than 2 sao of peanuts. Currently, 40 ha of peanuts in the winter-spring crop 2020-2021 in Tinh Tho commune participating in the intensive farming model have been synthesized with an average expected yield of 36.1 to 38.7 quintals/ha. In which, LDH.01 variety reached 36.1 quintals/ha; LDH.09 variety reached 38.7 quintals/ha; L14 variety reached 36.6 quintals/ha. Meanwhile, traditional peanut varieties only reach 26.3 quintals/ha. Accordingly, the revenue of peanut variety LDH.01 is over 90 million VND/ha, selling price is 25,000 VND/kg, minus expenses, profit is over 47.4 million VND/ha, more than 28.5 million VND higher than peanut variety. /ha. Sales of peanut variety LDH.09 profit reached over 53.9 million VND/ha, 35 million VND/ha higher than peanut variety; sales of peanut variety L14, profit reached over 48.6 million VND/ha, higher than peanut variety over 29.8 million VND/ha.

According to the planting experience of households in Phuoc Vinh commune, Ninh Phuoc district, custard-apple is quite well adapted to sandy soil as well as hot and dry local climate. Plants are easy to care for, resistant to many types of pests and diseases, cost less to buy fertilizers and fertilizers. After nearly three years of care, custard-apple harvested the first fruit, the average weight per fruit from six ounces to more than 1 kg. When ripe, fruit is very fragrant, sweet taste, chewy flesh, few seeds, less cracking when ripe, so it is easy to harvest and transport. Trees are propagated by grafting method. During the care process, it is necessary to provide enough water to irrigate the plants, especially in the dry season, to prevent weeds, mealybugs and thrips. In order for the tree to produce beautiful fruit and to limit pests and diseases, growers need to carry fruit since the fruit is as big as a chicken egg, and at the same time use a support tree so that the custard-apple tree will not break its branches when the fruit is large. The initial investment cost (including seeds, fertilizers, plant protection products) to plant a sao of custard-apple is about 10 million VND, about 80 to 100 trees / pole. Usually three years after planting, the Queen soursop gives fruit, the time from flowering to fruit harvest is about 5 months. Each tree gives harvest from 30 to 40 kg / crop and increases gradually as the tree grows. After harvesting is complete, it is necessary to prune, create canopy, fertilize and supplement nutrients so that the plants begin to flower for the next season. Queen custard apple has a purchase price of two to three times higher than that of our custard apple, about 60 to 70 thousand dong / kg; On holidays, Tet the selling price is higher. It is known that Ninh Thuan currently has nearly 18 hectares of new varieties of custard apple and more than 341 hectares of custard apple. In order to improve the production efficiency for the people, the Provincial Agricultural Extension Center is implementing seedling support programs, training on intensive farming techniques of Empress Soursop in the direction of VietGAP, guiding techniques for watering. saving, pollinating flowers, ways for plants to flower off-season, fruit wrapping techniques, preserving fruit after harvest to provide quality products to the market.

Area planted with genetically modified maize in Tho Hai commune (Tho Xuan). Accordingly, units under the Department of Agriculture and Rural Development have planted some genetically modified maize varieties, such as: DK 6818S, NK 4300BT / GT, NK 7328BT / GT, DK 9955S, NK4300Bt / Gt. , DK6919S … in some localities in the province. The actual assessment shows that the genetically modified maize varieties are highly resistant to pests and diseases, especially for dangerous diseases such as the autumn acacia, so the input cost is reduced by about 10 to 15%. Therefore, the yield of genetically modified maize varieties was 15 to 20 quintals / ha / crop higher than conventional maize varieties and 5 to 7 million VND / ha / crop higher than conventional maize varieties. Due to the proof of economic efficiency, the suitability of farming conditions and qualifications of many localities in the province, in recent years, the agricultural sector and local authorities in the province have encouraged her to Farmers put genetically modified maize varieties into production. Therefore, the model of genetically modified maize is increasingly being replicated, the area planted to genetically modified maize has been expanded according to each production season. In the summer-autumn crop of 2019, Tho Xuan District Agricultural Extension Center (now the Agricultural Service Center of Tho Xuan district) cooperates with DEKALB Co., Ltd. to implement a demonstration model of 2 genetically modified hybrid maize varieties 6919S and DK 9955S, in Tho Hai commune, with 2 sao. These are considered to be 2 genetically modified maize varieties with high yield and superior resistance to the autumn acacia worms. Accordingly, the company has put 2 genetically modified maize varieties: 6919S and DK 9955S into cultivation on the maize land area of ​​Tho Hai commune for trial planting. The actual evaluation from the model shows that, on 2 control maize fields planted adjacent to each other, the maize cultivating area is often destroyed by the autumn acacia worm, affecting the growth, development and yield. However, the planted area of ​​2 genetically modified maize varieties 6919S and DK 9955S still grows and develops well, the rate of damage caused by the autumn acacia and some other pests is low, almost does not affect the quality and productivity. According to calculations of the households implementing the model, the area of ​​genetically modified maize yield from 78 to 80 quintals / ha / crop, about 16 quintals / ha / crop higher than conventional maize varieties, the profit is from 27 to 33 million VND / ha / crop, about 7 million VND / ha / crop higher than the area planted with conventional maize varieties. At the end of the model, many households in Tho Hai commune boldly use genetically modified maize varieties for mass cultivation. On average, each year, the whole commune has about 100 ha of maize planted with genetically modified maize varieties. Particularly in the winter-spring crop 2020-2021, the whole commune has more than 30 hectares of maize planted with genetically modified maize varieties. In Yen Dinh district, genetically modified maize varieties, such as NK4300Bt / Gt, DK6919S, NK7328Bt / Gt, and DK6818S are also being widely cultivated by farmers in many lands. Each year, the district has nearly 1,000 ha of maize planted with genetically modified maize varieties and it is expected that the area of ​​using genetically modified maize varieties for cultivation will be expanded in the next seasons. According to Mr. Trinh Xuan Quy, Head of Agriculture and Rural Development Division, People’s Committee of Yen Dinh district, said: The reason for the rapid expansion of genetically modified marine maize area is because the use of genetically modified maize varieties helps to reduce labor, investment costs and amount of pesticides, thereby, reducing environmental pollution, improving farmers’ income, increasing economic efficiency from 15 to 20% compared to production of ordinary maize. From the benefits brought, Yen Dinh district is continuing to encourage farmers to use genetically modified maize varieties for planting, improving economic efficiency. According to the synthesis of the Provincial Plant Protection and Cultivation Department, the presence of genetically modified maize has been expanded in many districts, such as Cam Thuy, Yen Dinh, Tho Xuan, Ngoc Lac, Vinh Loc, Thieu Hoa, Trieu Son, with a total area of ​​more than 3,000 hectares per year. Most of the area planted to genetically modified maize achieves 20-30% higher economic efficiency than conventional maize varieties. More importantly, the genetically modified maize varieties are highly resistant to pests and diseases, so the amount of pesticide use in the production process is low, significantly contributing to environmental protection, ensuring safety. whole food for product
