Agronomic characteristics and environmental requirements<\/strong><\/span><\/h2>\n

Rice is the most important food crop, accounting for the highest area and output. In our country, rice can be grown in different regions of our country but is most grown in the Mekong Delta, Red River Delta and Central Coastal Delta.
\nRice is an annual crop that can be grown on many different types of soil such as alluvial soil, alum soil, gray soil, and sandy soil. Rice is a water-loving crop, the suitable temperature for rice is 20-30oC. Rice can be grown in all seasons, but there are usually two main rice crops a year: the Winter-Spring rice crop and the Summer-Autumn rice crop. Depending on the growth characteristics of rice varieties, people divide them into varieties. Rice: seasonal rice varieties (>140 days), mid-season rice varieties (105-140 days) and short-term rice varieties (<105 days).<\/p>\n

Rice plants can be planted in different forms: sowing (wet sowing, dry sowing, underground sowing) or transplanting (field seedling, yard seedling, tray seedling, ...). Wet sowing (regular sowing) is the most popular method of rice cultivation in the Mekong Delta.<\/p>\n

Nutritional requirements<\/strong><\/span><\/h2>\n

Rice plants need all 3 groups of macronutrients, macronutrients and micronutrients, including macronutrients such as nitrogen, phosphorus and potassium.<\/p>\n

Rice plants need nitrogen throughout the growth process, but the highest amount of protein is needed during the seedling, tillering and tillering stages. Rice plants need a lot of phosphorus in the early stages of growth (seedlings and tillering). As for potassium, rice plants need a lot at the seedling, flowering and flowering stages.<\/p>\n

Although rice plants need smaller amounts of secondary and trace elements, they are essential for rice growth and development, especially Si, Ca, Mg, Boron, etc.<\/p>\n

* Original fertilizer:<\/p>\n

The amount of fertilizer for rice depends on the rice variety, season and soil type. The table below shows how to fertilize short-term rice on some main soil types in the Mekong Delta.<\/p>\n\n\n\n\n\n\n\n

* Foliar fertilizer:<\/p>\n

Rice plants can quickly and effectively absorb nutrients through their leaves. Foliar spraying is a method of supplementing nutrients, especially micronutrients, during the plant's nutrient crisis period at the time of tillering, flowering, before and after flowering.<\/p>\n
