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. By eliminating the need for transplanting, farmers can cut down on labor costs and effectively manage the workforce during peak periods. It also provides flexibility in timing the planting, helping farmers to adapt to changing climate conditions. Moreover, DSR offers water efficiency. Traditional rice farming involves flooding fields, which is water-intensive and often unsustainable. Direct seeding of rice, on the other hand, requires less water during the establishment period, making it an attractive solution in regions experiencing water scarcity. Reduced water usage in DSR systems can help lower methane emissions, a potent greenhouse gas significantly produced in flooded rice paddies. [4]
One of the most significant hurdles is weed control. In flooded paddies, water serves as a natural barrier to weed growth. However, in DSR systems, weeds can grow alongside rice, reducing yield. Thus, effective weed management strategies are critical for the successful application of DSR.
Another concern is the need for precision in seed placement. Unlike transplanting, where seedlings are carefully placed in fields, direct seeding requires accurate equipment to ensure optimal plant density and uniform growth. Technological advancements, such as laser-assisted land leveling and drill seeders, are paving the way for overcoming these challenges, making DSR an increasingly feasible option for farmers.
Finger millet is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Africa and Asia. It is a tetraploid and self-pollinating species probably evolved from its wild relative Eleusine africana.
Tillage is the agricultural preparation of soil by mechanical agitation of various types, such as digging, stirring, and overturning. Examples of human-powered tilling methods using hand tools include shoveling, picking, mattock work, hoeing, and raking. Examples of draft-animal-powered or mechanized work include ploughing, rototilling, rolling with cultipackers or other rollers, harrowing, and cultivating with cultivator shanks (teeth).
Intensive agriculture, also known as intensive farming, conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital, labour, agrochemicals and water, and higher crop yields per unit land area.
A seedbed or seedling bed is the local soil environment in which seeds are planted. Often it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field. A seedling bed is used to increase the number of seeds that germinate.
The stale seed bed or false seed bed method is a weed control technique used at both the farm and garden scales. In this that the young weeds can then be easily eliminated. By destroying them early, the farmer or gardener eliminates most of that season's annual weeds, which reduces their labor and improves their crop yields.
Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.
In agriculture, polyculture is the practice of growing more than one crop species together in the same place at the same time, in contrast to monoculture, which had become the dominant approach in developed countries by 1950. Traditional examples include the intercropping of the Three Sisters, namely maize, beans, and squashes, by indigenous peoples of Central and North America, the rice-fish systems of Asia, and the complex mixed cropping systems of Nigeria.
A paddy field is a flooded field of arable land used for growing semiaquatic crops, most notably rice and taro. It originates from the Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with pre-Austronesian and Hmong-Mien cultures. It was spread in prehistoric times by the expansion of Austronesian peoples to Island Southeast Asia, Madagascar, Melanesia, Micronesia, and Polynesia. The technology was also acquired by other cultures in mainland Asia for rice farming, spreading to East Asia, Mainland Southeast Asia, and South Asia.
Aeroponics is the process of cultivating plants in an air or mist environment, eliminating the need for soil or an aggregate medium. The term "aeroponic" originates from the ancient Greek: aer (air) and ponos. It falls under the category of hydroponics, as water is employed in aeroponics to deliver nutrients to the plants.
The System of Rice Intensification (SRI) is a farming methodology that aims to increase the yield of rice while using fewer resources and reducing environmental impacts. The method was developed by a French Jesuit Father Henri de Laulanié in Madagascar and built upon decades of agricultural experimentation. SRI focuses on changing the management of plants, soil, water, and nutrients to create a more productive and sustainable system of rice cultivation.
Controlled-environment agriculture (CEA) -- which includes indoor agriculture (IA) and vertical farming—is a technology-based approach toward food production. The aim of CEA is to provide protection from the outdoor elements and maintain optimal growing conditions throughout the development of the crop. Production takes place within an enclosed growing structure such as a greenhouse or plant factory.
Intensive crop farming is a modern industrialized form of crop farming. Intensive crop farming's methods include innovation in agricultural machinery, farming methods, genetic engineering technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, patent protection of genetic information, and global trade. These methods are widespread in developed nations.
Agriculture accounts for 22 percent of Cambodia’s GDP, and employs about 3 million people.
Upland rice is rice grown in drier environments. The term describes varieties of rice developed for rain-fed or less-intensely irrigated soil instead of flooded rice paddy fields or rice grown outside of paddies.
Rice production in China is the amount of rice planted, grown, and harvested for consumption in the mainland of China.
Perennial rice are varieties of long-lived rice that are capable of regrowing season after season without reseeding; they are being developed by plant geneticists at several institutions. Although these varieties are genetically distinct and will be adapted for different climates and cropping systems, their lifespan is so different from other kinds of rice that they are collectively called perennial rice. Perennial rice—like many other perennial plants—can spread by horizontal stems below or just above the surface of the soil but they also reproduce sexually by producing flowers, pollen and seeds. As with any other grain crop, it is the seeds that are harvested and eaten by humans.
Large scale rice production in the state of Arkansas became a significant industry in the late 19th/early 20th century with its wide scale propagation within the state by entrepreneur W.H. Fuller around 1896. Arkansas has historically been the largest rice producer in the entire United States, and accounted for nearly 45% of U.S. rice production in 2001, as well as just less than half of the total number of acres of rice harvested nationwide. Much of Arkansas' rice is grown in the east-central portion of the state, where it requires nearly three times more the amount of irrigation water than the average eleven inches the region receives during the growing season. In the areas of lowest precipitation, or where weedy red rice is a significant problem, farmers follow a three year, three phase "old rotation" of rice-soybean-soybean. However, most Arkansas rice producers follow a two year, two phase crop rotation of rice following soybeans.
Alternate wetting and drying (AWD) is a water management technique, practiced to cultivate irrigated lowland rice with much less water than the usual system of maintaining continuous standing water in the crop field. It is a method of controlled and intermittent irrigation. A periodic drying and re-flooding irrigation scheduling approach is followed in which the fields are allowed to dry for few days before re-irrigation, without stressing the plants. This method reduces water demand for irrigation and greenhouse gas emissions without reducing crop yields.
