Inefficient cultivation of peanuts on fertile soils

Some peanut varieties of the Institute of Agricultural Science and Technology of the South Central Coast have been selected for intensive cultivation for high yield and value.
In recent years, implementing a project on applying science and technology to build an inefficient peanut-growing area on rice and non-crop land along the value chain in Tinh Tho commune, Son Tinh district (Quang Ngai), Son Tinh district has implementing the model of intensive farming of peanuts on rice and cash crops inefficiently in Tinh Tho commune.

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.

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.

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.
