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. [2] 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, [3] as well as just less than half of the total number of acres of rice harvested nationwide. [4] 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. [5] 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. [3]
The origins of rice cultivation within the state of Arkansas, as well as within the entire Grand Prairie region, is typically attributed to Nebraskan entrepreneur W.H. Fuller's move to Lonoke County, Arkansas and subsequent planting of rice throughout the region. The idea to plant rice in Arkansas came to Fuller in August 1896, when he was travelling to Louisiana with companion Hewit Puryear for a hunting trip. Along their horse and wagon trip, the two men were especially captivated by a rice field in the southern Louisiana town of Crowley. It was in front of these fields that Fuller realized "...we had a good rice country if we had the water. At that time there were no wells [near Crowley] but they were talking of making wells, which gave me the idea of wells here." Fuller was initially successful, but later realized that he had yet to master the techniques of rice cultivation, and so in 1898 embarked with fellow Nebraskan farmer John Morris back to Louisiana to perfect these techniques. Fuller returned to Arkansas in 1903 a master of rice farming, sowing acres of it in 1904, from which he harvested over 5,000 bushels. [5]
The annual Arkansas rice crop is crucially integral to the state's economy, contributing more than $6 billion to the state's economy every year and accounts for over 25,000 jobs. [2] Being such a large system with many interrelated factors, the factors that impact the profitability of Arkansas rice are diverse and numerous. For example, the Arkansas rice producers' profit margins are directly impacted by domestic farm prices, which are in turn firmly connected to global market prices. Along with this, government payments also directly impact Arkansas farm revenues, and in turn the quality of the crop/its profitability due to the programs and methods the government encourages (such as crop mixing as a way to manage risk). Economic return of rice crops within Arkansas vary markedly depending on variety cultivated, methods of crop rotation, region of the state it is grown in, methods of cultivation, etc. For example, "continuous rice produced the largest gross returns [from 2000-2001] per hectare on average, ranging from $936.94 ha−1 to $1195.83 ha−1," whereas "the rice-corn rotation produced the smallest gross returns on average," only yielding $749.24 ha−1 to $1003.79 ha−1. [3]
Of all the rice producing states, Arkansas continues to be the largest in terms of acres of rice planted as well as production. In 2003, Arkansas had 1,466,600 acres planted with rice. California and Louisiana, the two states runner up to Arkansas in these categories, had only 509,000 and 455,000 acres of rice under cultivation in the same year, respectively. The five largest rice-producing counties in the state of Arkansas were Poinsett (134,944 harvested acreage), Arkansas (117,675 harvested acreage), Cross (106,254 harvested acreage), Jackson (101,762 harvested acreage), and Lawrence (99,480 harvested acreage) in the year 2003, which represented nearly 36% of the state's total land acreage under rice production. [7]
Rice is an extremely water intensive crop, and as a result requires quite a bit of irrigation "that must be secured from other sources." [5] However, Arkansas rice growers have adopted water saving irrigation practices where natural slopes and soil depths can be utilized in order to retain water. One such method that is being adopted more and more by rice farmers in Arkansas is straight-levee rice cultivation. [8] Other common methods of irrigation include flood/levees, of which 1,089,036 acres of rice (74.9% of total acreage) were irrigated with in the year 2003, as well as flood/multiple inlets, of which 361,168 (24.8% of total acreage) acres were irrigated with in the same year. [7]
Arkansas rice is typically grown in drilled rows, which are flooded at the four to six leaf stage (usually four to five weeks after planting), under a dry seeded culture. [9] Many Arkansas rice farmers still rely on conventional tillage methods for planting their rice, such as farmer Dow Brantley of England, Arkansas who reported in 2005 that he "still plants about 20 percent of his 1,200 acre rice crop in conventional tillage methods." Planting the majority of his rice with no till methods, Brantley has found that "reduced till rice...advantages include: lower production costs, more profit per acre, less labor demand (the same labor handles more acres), less wear on equipment, more residue (that helps with more cotton), and less red rice pressure, especially with continuous rice." [10]
As with many issues pertinent to rice farming in Arkansas, the rates and methods of fertilization vary depending on a number of factors. Nitrogen fertilization, as with many crops grown in the United States, often plays a significant role in the growth of rice within Arkansas. The University of Arkansas Division of Agriculture (U.A.D.A.) suggests different amounts of Nitrogen addition to soil depending on such factors as soil type, rice variety being grown, crop rotation, etc. For example, the U.A.D.A. recommends 150 lb. N/acre ("this recommendation is for N applied in a 2 or 3-way split application where 90 lb N/acre is applied preflood and followed by 60 lb N/acre at midseason") for Wells rice grown in rotation with soybeans on silt/sandy-loam soils. However, a simple change in soil texture from silt/sandy-loam soil to a clay soil induces a 30 lb per acre increase in the recommended amount of nitrogen to be added to the soil. [11]
The most prominent varieties of rice planted within Arkansas, with their respective percentages of acreage occupied of total area under rice cultivation are: Wells (45.2%), Cocodrie (21.8%), Bengal (11.2%), Francis (6.3%), CL 161 (4.7%), and LaGrue (2.6%). [7] Wells, the most prominent variety of rice grown in Arkansas, is a long grain rice actually developed by the University of Arkansas Agricultural Experiment Station in February 1999 in order to increase yields of the crop. [11] Though the long grained Wells variety essentially dominates the rice fields of Arkansas, "Bengal is a successful southern medium-grain released in 1993 and is still the leading medium-grain variety grown in Arkansas." [13]
Yamada Nishiki is a specialty variety cultivated for sake production. [14]
A number of diseases and pests pose threats to rice cultivation within the state of Arkansas. One such culprit, Pyricularia grisea, commonly known as rice blast, is an invasive fungus that spreads primarily through infected rice stubble from the prior year, related host species and even sometimes infected seed. [16] Though epidemics of the fungus seem to be sporadic (infected seed most likely accounts for the randomness in distribution of the rice blast in Arkansas rice fields), "rice blast has caused significant yield losses in Arkansas." [16] Another disease that is actually "second only to, and often rivals, rice blast in importance" is sheath blight, which is a soil borne pathogen the initial symptoms of which commonly begin with "lesions on the sheaths of lower leaves when plants are in the late tillering or early internode elongation stage of growth." [17] The weed that poses perhaps the largest threat to Arkansas rice is barnyard grass, due to its "widespread resistance to propanil and quinclorac, two of the most frequently used herbicides." [9] Along with this, "weedy red rice ( Oryza sativa ) is a problematic weed in cultivated rice," and of the rice fields in Arkansas that account for 50% of the nation's rice crop, "about 60% of these...have some red rice infestation." [18] Weeds such as barnyard grass and weedy red rice can often have detrimental effects to rice fields throughout the state of Arkansas, accounting for over $22 million worth of crop yield losses in 1992. [19]
Panicum miliaceum is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. Major cultivated areas include Northern China, Himachal Pradesh of India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the Great Plains states of the United States. About 500,000 acres are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet.
Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. This practice reduces the reliance of crops on one set of nutrients, pest and weed pressure, along with the probability of developing resistant pests and weeds.
A sugar beet is a plant whose root contains a high concentration of sucrose and that is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet. Together with other beet cultivars, such as beetroot and chard, it belongs to the subspecies Beta vulgaris subsp. vulgaris but classified as var. saccharifera . Its closest wild relative is the sea beet.
Organic farming, also known as ecological farming or biological farming, is an agricultural system that uses fertilizers of organic origin such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. It originated early in the 20th century in reaction to rapidly changing farming practices. Certified organic agriculture accounts for 70 million hectares globally, with over half of that total in Australia. Biological pest control, mixed cropping, and the fostering of insect predators are encouraged. Organic standards are designed to allow the use of naturally-occurring substances while prohibiting or strictly limiting synthetic substances. For instance, naturally-occurring pesticides such as pyrethrin are permitted, while synthetic fertilizers and pesticides are generally prohibited. Synthetic substances that are allowed include, for example, copper sulfate, elemental sulfur, and veterinary drugs. Genetically modified organisms, nanomaterials, human sewage sludge, plant growth regulators, hormones, and antibiotic use in livestock husbandry are prohibited. Organic farming advocates claim advantages in sustainability, openness, self-sufficiency, autonomy and independence, health, food security, and food safety.
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.
Thlaspi arvense, known by the common name field pennycress, is a flowering plant in the cabbage family Brassicaceae. It is native to Eurasia, and is a common weed throughout much of North America and its home.
A crop is a plant that can be grown and harvested extensively for profit or subsistence. In other words, a crop is a plant or plant product that is grown for a specific purpose such as food, fibre, or fuel.
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.
During the Sangam age, 500 BCE – 300 CE, agriculture was the main vocation of the Tamil. It was considered a necessity for life, and hence was treated as the foremost among all occupations. The farmers or the Ulavar were placed right at the top of the social classification. As they were the producers of food grains, they lived with self-respect. Agriculture during the early stages of Sangam period was primitive, but it progressively got more efficient with improvements in irrigation, ploughing, manuring, storage and distribution. The ancient Tamils were aware of the different varieties of soil, the kinds of crops that can be grown on them and the various irrigation schemes suitable for a given region. These were also in Madras, Thanjore.
The southeast Asian country of Laos, with a landmass of 23.68 million hectares, has at least 5 million hectares of land suitable for cultivation. Seventeen percent of this land area is actually cultivated, less than 4 percent of the total area.
Rice production in Laos is important to the national economy and food supply.
The term cropping system refers to the crops, crop sequences and management techniques used on a particular agricultural field over a period of years. It includes all spatial and temporal aspects of managing an agricultural system. Historically, cropping systems have been designed to maximise yield, but modern agriculture is increasingly concerned with promoting environmental sustainability in cropping systems.
Organic beans are produced and processed without the use of synthetic fertilizers and pesticides. In 2008, over 2,600,000 acres (11,000 km2) of cropland were certified organic in the United States. Dry beans, snap beans, and soybeans were grown on 16,000 acres (65 km2), 5,200 acres (21 km2), and 98,000 acres (400 km2), respectively.
Farming systems in India are strategically utilized, according to the locations where they are most suitable. The farming systems that significantly contribute to the agriculture of India are subsistence farming, organic farming, industrial farming. Regions throughout India differ in types of farming they use; some are based on horticulture, ley farming, agroforestry, and many more. Due to India's geographical location, certain parts experience different climates, thus affecting each region's agricultural productivity differently. India is very dependent on its monsoon cycle for large crop yields. India's agriculture has an extensive background which goes back to at least 9 thousand years. In India, in the alluvial plains of the Indus River in Pakistan, the old cities of Mohenjo-Daro and Harappa experienced an apparent establishment of an organized farming urban culture. That society, known as the Harappan or Indus civilization, flourished until shortly after 4000 BP; it was much more comprehensive than those of Egypt or Babylonia and appeared earlier than analogous societies in northern China. Currently, the country holds the second position in agricultural production in the world. In 2007, agriculture and other industries made up more than 16% of India's GDP. Despite the steady decline in agriculture's contribution to the country's GDP, agriculture is the biggest industry in the country and plays a key role in the socio-economic growth of the country. India is the second-largest producer of wheat, rice, cotton, sugarcane, silk, groundnuts, and dozens more. It is also the second biggest harvester of vegetables and fruit, representing 8.6% and 10.9% of overall production, respectively. The major fruits produced by India are mangoes, papayas, sapota, and bananas. India also has the biggest number of livestock in the world, holding 281 million. In 2008, the country housed the second largest number of cattle in the world with 175 million.
The production of corn plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of its annual yield is exported.
Rice production is the fourth largest among cereals in the United States, after corn, wheat, and sorghum. Of the country's row crop farms, rice farms are the most capital-intensive and have the highest national land rental rate average. In the US, all rice acreage requires irrigation. In 2000–09, approximately 3.1 million acres in the US were under rice production; an increase was expected over the next decade, to approximately 3.3 million acres. USA Rice represents rice producers in the six largest rice-producing states of Arkansas, California, Louisiana, Mississippi, Missouri, and Texas.
Vigna angularis, also known as the adzuki bean(Japanese: 小豆, azuki, Uncommon アヅキ, adzuki), azuki bean, aduki bean, red bean, or red mung bean, is an annual vine widely cultivated throughout East Asia for its small bean. The cultivars most familiar in East Asia have a uniform red color, but there are also white, black, gray, and variously mottled varieties.
The sugar industry of the United States produces sugarcane and sugar beets, operates sugar refineries, and produces and markets refined sugars, sugar-sweetened goods, and other products. The United States is among the world's largest sugar producers. Unlike most other sugar producing countries, the United States has both large and well-developed sugarcane and sugar beet industries. Refined sugarcane, processed sugar beet, and high-fructose corn syrup are all commonly used in the U.S. as added sugars to sweeten food and beverages.
