Direct seeded rice (DSR) [2] [3] is a practice of sowing paddy which involves planting rice seeds directly into the field, instead of the traditional method of growing seedlings in nurseries and then transplanting them into the fields. This method significantly reduces the demand for labor, one of the major costs associated with rice farming.
When seeds are sown directly into the soil, the seeds and young plants can be damaged by drought conditions before floods arrive. During this stage, the plants can also suffer due to competition from weeds. Sudden flooding, where a large volume of water enters the field in a short time, can lead to a high level of seedling death. [8]
Scarification is often done mechanically, thermally, and chemically. The seeds of many plant species are often impervious to water and gases, thus preventing or delaying germination. Any process designed to make the testa (seed coat) more permeable to water and gases is known as scarification.
Fiber mulch accelerates the growing process by maintaining moisture around the seeds thereby increasing the rate of germination. [4] Seeds are applied to tilled soil using a high pressure hose. The seeds are likely mixed into a water-based spray that often contains mulch, fertilizer, lime, or other substances that promote seed growth. [5]
Liu Shiping's team at Yangzhou University created rice varieties that can be grown in salt water, and achieve yields of 6.5 to 9.3 tons per hectare. [ 13 ] [ 14 ] As of 2021, seawater rice had been planted on 400,000 ha (990,000 acres) in soils with up to 4 grams of salt per kilogram, with yields averaging 8.8 tons per hectare, according to ...
Reduced water consumption: This is because rice plants do not require continuously flooded conditions to grow, [13] and that water savings can be achieved without compromising yields. Studies have shown that SRI can reduce water use by 25-50% compared to conventional rice farming, while maintaining or increasing yields.
Rice water for hair. Rice water contains an antioxidant called inositol, which is considered to be a "hair rejuvenator," reveals Khetarpal. Inositol may help hair grow faster and become healthier ...
Because of the installed tubes in the field, it is possible to monitor the water depth below the soil surface up to 15–20 cm. When the water level drops 15 cm below the soil surface, irrigation should be applied in the field to re-flood to a depth of 5 cm. During the flowering stage of the rice, the field should be kept flooded.
