Urochloa mutica is a species of grass known by the common names para grass, buffalo grass, Mauritius signal grass, pasto pare, malojilla,gramalote, parana, Carib grass, and Scotch grass. Despite its common name California grass, it does not occur in California; it is native to Africa, where it is cultivated for fodder. It was introduced elsewhere and it is now cultivated throughout tropical regions of the world for this purpose.
Digitaria is a genus of about 300 species of grass (family Poaceae) native to tropical and warm temperate regions. Common names include crabgrass,finger-grass, and fonio. They are slender monocotyledonous annual and perennial lawn, pasture, and forage plants; some are often considered lawn pests. Digitus is the Latin word for "finger", and they are distinguished by the long, finger-like inflorescences they produce. 20-60 All crabgrasses have similar growth habits and flowering structures, but species are separated by minor differences in the flower structures and leaf pubescence.
Sorghum halepense, commonly called Johnson grass, is a plant in the grass family, Poaceae, native to the Mediterranean region, but growing throughout Europe and the Middle East. The plant has been introduced to all continents except Antarctica, and larger islands and archipelagos. It reproduces by rhizomes and seeds.
Imelda Grass or more popularly known as Imelda Flower could be seen sprouting all around Gensan. Legend says that it was former First Lady Imelda Marcos who introduced it here in the 70s upon noticing that the area was one hot, arid desert. This thorny grass which is also known as Imelda creeper thrives well in sandy areas and needs minimal water.
Cynodon dactylon (syn. Panicum dactylon, Capriola dactylon), also known as dūrvā grass, Bermuda grass, bermudagrass, dubo, dog's tooth grass, Bahama grass, devil's grass, couch grass, Indian doab, arugampul, grama, and scutch grass, is a grass native to north and east Africa, Asia, Australia and southern Europe. Although it is not native to Bermuda, it is an abundant invasive species there. It is presumed to have arrived in North America from Bermuda, resulting in its common name.
The carabao grass is a kind of grass that is very common in the American tropics and tropical countries especially in Southeast Asia. It can be found in abundance in countries like the Philippines, Indonesia and the Pacific islands. The grass originated from the American tropics and is eventually naturalized in other tropical nations all over the world. It has a scientific name of Paspalum conjugatum Bergius.
Pennisetum purpureum also known as Napier grass, elephant grass or Ugandan grass is a species of perennial tropical grass native to the African grasslands. It has low water and nutrient requirements, and therefore can make use of otherwise uncultivated lands. Historically, this wild species has been used primarily for grazing; recently, however, it has been incorporated into a pest management strategy.
Euphorbia hirta, known in the Philippines as "Tawa-tawa" or “gatas-gatas,” is a hairy herb grown in open grasslands, roadsides and pathways. This indigenous plant is claimed to have a curative effects on dengue patients as being backed up by personal testimonies, it became one of the most popular “folkloric medicine” for dengue in the Philippines. However, despite its widespread use, there is no evidence to support this claim.
Amaranthus, collectively known as amaranth, is a cosmopolitan genus of annual or short-lived perennial plants. Catkin-like cymes of densely packed flowers grow in summer or autumn. Approximately 60 species are recognized, with inflorescences and foliage ranging from purple and red to green or gold. Members of this genus share many characteristics and uses with members of the closely related genus Celosia.
Cyperus rotundus (coco-grass, purple nut sedge, red nut sedge, is a species of sedge (Cyperaceae) native to Africa, southern and central Europe (north to France and Austria), and southern Asia.

My Village

...right of the village flows quietly a clear and blue river. When I was young, I used to swim in the river with my friends. How can I forget the wonderful time on this river fishing or rowing a boat with my boyhood friends! On the left of the village lies the village green where village meetings are often held by village officials. On this ground covered with soft grass we used to fly kites on windy autumnal evenings. The majority of villages live on agriculture. They get rich thanks to their fertile rice-fields and their diligence. Harvest time is certainly the busiest and the merriest time of the year. During the harvest, the villagers often get up very early in the morning. They cheerfully go to their rice-fields to harvest the bumper crop – the fruit of many months of hard work. My villagers are very friendly and helpful. They are willing to offer mutual help in any case and always get on with one another harmoniously. My village is rather small indeed but I like it very much because I was born and have grown up there and spent my happiest childhood among the simple and hard-working villagers who always feel attached to their native...

Concept of Pest

...injures man, his property, or his environment, or which just causes him annoyance. Such organisms include principally certain insects, nematodes, fungi, weeds, birds and rodents, or any other terrestrial or aquatic plant or animal life, or virus, bacteria, etc. In agriculture, concern is normally expressed when the damage done to a crop by a specific crop pest or a group of pests causes a loss in yield or quality because this would mean a reduction in profit. When a loss in yield reaches certain proportions, the pest can be designated an economic pest. According to Edward and Heath (1964), the pest status is reached when there is a 5 percent loss in yield in a particular crop. In pest management, the economic appraisal of the pest status and justification of the need to embark on control measures is defined in relation to the following concepts: economic damage, economic injury level and economic threshold. Economic damage can be defined as the amount of injury done to a crop that will justify the cost of artificial control measures. Economic injury level is the lowest pest population density that can cause economic damage, which will vary from crop to crop, season to season, and area to area. For practical purposes, there is an economic threshold defined by Stern et al. (1959) as the pest population density at which control measures should be initiated or started to prevent an ever increasing pest population from reaching the economic injury level. The economic threshold is conceptualized...

What Does This Contract Reveal to You About the Nature of Sharecropping? Was This System a Good One for Both the Sharecropper and the Landowner?

...believe what the contract reveals about the nature of sharecropping is that it was set up to set the “freed” African American for failure and to put them in such debit that they basically became slaves to the landowner once again. The landowner has left a lot of responsibility to the sharecropper obviously I think a good example of this in this contract is that the landowner has agreed to provide the team but the sharecropper has to feed the team Saturday nights, and every other day morning night a day and if he fails to provide the meal he will then owe the landowner 5 cents, which was a lot of money at the time especially for a poor sharecropper. He also has to pay for his half of the manure which the landowner designates as enough of the crops. This system is so beneficial to the landowner but only allows the sharecropper enough to thrive to live. I don’t believe this system was good for both the sharecropper and the landowner. I believe as earlier stated it was one sided to the landowner. The sharecropper had a lot of responsibility while all the landowner did was provided the land and horses for the sharecropper and then reaped all the benefit finically. He got a low cost of labor and once the debit piled up from the landowners harsh expectations basically free labor out of this. This landowner even went as far to make the sharecropper “sow and haul” his oats but of course the sharecropper was not allowed to take part in any of them. Also if the sharecropper does not meet...

The Indian Farmer

...India is an agricultural country. Eighty percent of Indians earn their living by working on land. The Indian farmer is the backbone of the Indian society because he feeds us and supplies us with food grains. He provides us with raw materials for cloth, fire-wood and timber. He works very hard from morning to evening. He has to get up early in the morning and plough the land. From the ploughing of the fields he turns to the feeding of the cattle. Hardly does he finish hoeing when he takes to weeding or watering. He takes his breakfast in the fields and works on till noon. He enjoys simple food, fresh air and sound sleep at night. His living depends on the rain god. He is ruined if his crops fail due to lack of rain or drought. He is happy if the harvest is growing. When the crop fails, he borrows money and runs into debt. The Indian farmer spends his life in the lap of nature. An Indian farmer is generally illiterate. He is often used to drinking heavily. Since the freedom of the country, the lot of the Indian farmer is improving. He is being encouraged by the government to improve his lot by increasing production. He is being given loans to buy farm inputs and to have tube wells and pumping sets. Free and compulsory education goes a long way in bringing about a great change. The Indian farmer is growing more, earning more and has a better standard of...

Echo Field Trip

...ECHO FIELD TRIP On this wonderful tour, I learned a large amount of sustainable agricultural approaches. Crop rotation was one of them. It’s where the farmer grows different crops in the same field, in succession. Apparently, there are repercussions to planting the same crop over and over. This avoids those challenges. One challenge in particular is reducing the pest issue that most farmers face. These pests usually explode in population due to the continual availability of their food source. These pests tend to prefer one certain crop and by changing it yearly, the pest population stays down. These farmers also tend to plant crops that replenish the nutrients in the soil. Crops like soybeans and legumes reduce the need for the farmers to use fertilizer because it keeps the soil healthy. Farmers also use a method called “cover crops.” This method involves always having something growing in the soil. This prevents the soil from eroding, the weeds from growing, and it improves the quality of the soil. You will also see a large amount of farmers introduce “pest predators” onto their fields. Insects, birds, and spiders eat a lot of the pests that terrorize the crops of these farmers. These are just a few of the sustainable methods farmers use to keep their farms afloat. The biggest problem farmers’ face is the fact that there is an overgrowth of these pests. These pests are evolving and some pesticides are failing to work at this point. This forces farmers to introduce predators...

Itc E-Choupal Review

...appropriate tools that may help them achieve the maximum financial benefits. Farmers did not have access to quality inputs (pesticides, herbicides, etc.), or information on weather reports that may help improve their crop quality as well as the process of bringing it into the market. Because of this, farmers lost 60-70% of the potential value of their crop and the yield was only about a third to a quarter when compared to the global standards. ITC wanted to address the entire issue by helping the farmers earn their fair share, and improving the trading service. ITC wanted the farmers to have access to all the information, and have them make decisions on how they wanted to sell their crop. ITC enabled this by creating a Hub is each village which enabled them to attain information relating to weather, crops, best practices, and all their questions could be answered by an expert in the field. 2. What are the old and new physical flows and information flows in the channel? In the old system, the main source of physical flow and information flow in the channel was via the Mandi, where the farmers and villagers would gather to discuss information on various topics.

Farming

...Textual Analysis of “A Tale of Two Soils” This article was published in AgWeb on September 23, 2013. This article came out just before harvest started for 2013. The author talks about the problems farmers have had with crop yields. The article was written just before harvest started to give some insite as to why some fields produce higher yields of crops as opposed to other fields. Thought the article Smith talks about the main factors in crop productivity. The purpose of this article was to inform farmers what to helps fields produce larger yields of crops. Content The main point emphasized throughout this article is that the content of the soil plays a huge factor in crop yields. Throughout the article, Smith talks about how Farm A and Farm B both have the same soil make up, but Farm B produces an average of 70 bushel of crops less than Farm A. The author points out that both farms have a silty clay loam and a silt loam soil composition and are only a mile apart. Smith says that both farms are no-till farms, but Farm A has been no-till for thirty years and Farm B has only been no-till for four. Smith says, Ken Ferrie said, “Because of the difference in soil health, the best soil on Farm B still can’t yield a well as the poorest soil on Farm A.” Smith points out that it is becoming easier and easier for farmers to test their soil and pinpoint the exact culprit to lower yields. Smith says, Ken Ferrie said, “Improving soil health means sustaining productivity and...

Chicory

...principles, contribution to farming and the associated limitations- an analysis Summary Chicory (Cichorium intybus) is an increasingly popular crop that is excellent in providing high quality feed and high mineral content to grazing animals. Chicory is fast to establish and competitive for its resources given the right conditions, thus has high yields that occur in autumn, spring and summer. Yields expected, range from 8- 10t/ ha which consist of green leaf tissue which is valuable to New Zealand farms. The aim of the report is to find out the potential contribution of chicory to New Zealand farms by its agronomic principles, main advantages and the associated limitations. The literature covered in the findings is from Australian and New Zealand journals and websites, majority being by New Zealand researchers. Findings suggest that chicory is beneficial to New Zealand system under the right conditions following certain guidelines and recommendations. Deer and lambs can do better on chicory rather than the traditional ryegrass (table 1). Other findings suggest that climate change will have an impact on plant growth in chicory. Introduction Chicory is classed as a forage crop that belongs to the Asteracea family. It is commonly used as a specialist summer feed crop which is vital during summer and spring. Unique advantages of the crop ranges from maintaining and increasing the feed supply and quality whilst also providing a source of minerals to the grazing animal. Agronomic...

Strategies to Overcome Malnutrition

...across gullies. Those methods only use 5% of farmland but increase the crop yields over 50%. Fertilizer from local animals should be used instead of chemical fertilizer. Since fertilizer from animal is always available and free. Chemical fertilizer can cause disease. Simple, reliable, agricultural tools made should be used instead of tractors. Because tractors can be broken and farmers need money to repair them. Farmer can grow cash crops and subsistence crop together in smallholdings instead of cash crops (monoculture) on large estates. Farming mixes with crop rotation or intercropping will reduce soil erosion and exhaustion, protect crops (smaller plants protected by tree crops) and increase yields. For example, in Moc Chau district in Viet Nam, by using this method, crops yield is increased by 33% from 1994-2000. 2) Introduce a new “Green Revolution”: In Mexico, 2 decades after World War II, new varieties of wheat and maize were developed. They produced dwarf plants capable of withstanding strong winds, heavy rain and diseases. Yields of wheat and maize tripled and doubled. The IR-8 variety in Philippines has increased the crop yield by six times at its first harvest. The “super rice” has increased the yield by 25% (1994). Since then, more and more improvements have been made such as: the growing season is shortened, crops can...

...The study was undertaken with the focus on Minimum Support Price and its impact on various parameters of agricultural economy including growth parameters, distribution aspects, and decision making in allocation of resources, environmental effects and above all MSP as an effective instrument of the price policy. The study was mainly dependent upon the data collected from secondary sources at the state level and supported with the primary data. The price policy was more effective in case of paddy and wheat as compared to cotton in the Punjab State. Since 1990s, the gap between farm harvest price and MSP in case of paddy narrowed down considerably while for wheat, the farm harvest price was even lower than the MSP for some years. It was due to the reluctance shown by the Government to purchase large volumes of paddy and wheat arriving in different markets of the state due to lower storage capacity and already piled large stocks of food grains. The growth in MSP, wholesale price and farm harvest price for paddy, wheat and cotton was higher in period II (1985-86 to 1999-2000) as compared to period I (1970-71 to 1984-85). The farmers’ response regarding the awareness of MSP was the highest for wheat followed by paddy and cotton. The increase in MSP had induced the use of new technology and increase in output. Also, the impact of MSP in increasing the adoption of technology was found to be negatively associated with farm size. There was no regional disparity observed in procurement of...

It was really interesting to see the different types of farming. All three of them were completely different than what we do on my home farm. They shared pros and cons of how they farm, and what they’re doing in the future to make the way they farm better. What were the main concerns/observations/experiences of the speakers that formed the basis for their comments and/or recommendations? (about ½ page) Nathan talked about his 850 acre row crop operation. On his family farm, they also raise about 80 stock cattle on 50 acres of pasture. Something that they are experimenting with is planting cover crops on their row crops, and then grazing the cattle on the cover crops. This has worked so far, and they are looking to do more of this. Nathan thinks that grazing cover crops is a logical step for the best management of the farm. Doing this, Nathan believes it will be helpful for long term farming. Something that Nathan doesn’t like doing is spraying, therefore making it unsustainable. He is trying to figure out ways to reduce the amount of spraying and fertilizer that they use on his family farm. Mike operates an 858 acre bison farm.

Marketing Boards in Kenya

...Marketing is the process of creating consumer value in the form of goods, services, or ideas that can improve the consumer’s life. Marketing board is an organization created by many producers to try to market their product and increase consumption and thus prices. It can also be defined as an organization set up by a government to regulate the buying and selling of a certain commodity within a specified area. They most commonly exist to help sell farm products such as milk, eggs, beef or maize and are funded by the farmers or processors of those crops or products. Marketing boards often also receive funding from governments as an agricultural subsidy. The leadership and strategies of the marketing boards are set through votes by the farmers. Marketing boards also sometimes act as a pool, controlling the price of farm products by forming a legal cartel. They also fund other ventures beneficial to their members such as research. Marketing boards are state-controlled or state-sanctioned entities legally granted control over the purchase or sale of agricultural commodities. Since the mid-1980s they have declined in number under pressure from domestic liberalization and from international trade rules that increasingly cover agriculture. Where reforms have been widespread and successful, marketing boards have vanished or retreated to providing public goods, such as strategic grain reserves or insurance against extraordinary price fluctuations i.e. the National cereals board, the...
