what is multiple cropping answer

In relay inter cropping; there is some overlapping period of two crops. Subsistence: Grown just for the farmer and his family. Such multicrops may take the form of intercrops, where growth and yield are confined to a single growing season, or agroforestry, where a perennial component, e.g., trees or shrubs, occupies some of the land over a series of growing seasons. This is the main difference between them. A term denominated soil-loss tolerance is defined as the maximum amount of soil erosion that will permit a high level of productivity to be sustained both indefinitely and economically. Multiple cropping- It involves growing two or more crops on the same farmland during the same cropping season. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Encyclopedia of Applied Plant Sciences (Second Edition), PRODUCTION SYSTEMS AND AGRONOMY | Multicropping, Corn is grown in a multiple-cropping system. By multiple cropping farmers grow different crops on same piece of land. Food safety issues will dominate the future discussion on the use of chemical weed control in cassava systems. Biodiverse multicropping systems provide food for today and will impact broad future issues such as alleviation of poverty and hunger. Answer Multiple cropping and use of modern farming methods are two different ways of increasing production on the same piece of land. Taking into account the yield advantage and alternate herbicide costs, USEPA estimated the value of atrazine in corn at $28/A. The cropping intensity of Groundnut + Arhar â Sugarcane isâ (A) 200% (B) 300% (C) 150% (D) 250% Ans : (C) 118. Organic farms appear thus to often but not always have higher crop diversity than conventional farms. A) ... -- View Answer: 4). Although the cropping system is being simplified due to shortage of rural labor and mechanical planting, multiple cropping is still dominant. Rattan Lal, in Reference Module in Life Sciences, 2017. What is the simple meaning of literature? 3.4. how to crop multiple files. Here, a lower, shorter-duration crop complements the upper canopy of the plantation species. The choice of species for multicropping varies with geographical location, level of input, and local preference. Properly stored, cooked, How do bonsai trees stay small? Conservation tillage has many forms, ranging from those in which only a small slit is opened in the soil ahead of the planter unit to full-width tillage that could even involve a modified moldboard plow. how make multiple cut or crop of time series. Raising two or more crops in a field in a year in such a way that the second crop is planted before the harvest of first crop is called relay inter cropping. Both the branching and nonbranching cultivars are widely grown in southern Africa. 1. On the other hand, modern farming experiments with the implementation of advanced technology in the field of agriculture. Modern farming methods refer to the agricultural production system characterized by the high inputs of capital, labour, heavy usage of farm machinery such as threshers, harvesters, winnowing machine, heavy usage of technology such as selective breeding, pesticides, chemical fertilizers and insecticides. It is a form of polyculture. Such systems involve growing two or more crops on the same field in a year. Potential residual effects in the reservoir of nutrients, weeds, or pests and diseases with implications for the succeeding crop or crops. It makes use of hybrid seeds of selected variety of a single crop, technologically advanced equipment and lots of energy subsidies in the form of irrigation water, fertilizers and pesticides. Copyright © 2021 Elsevier B.V. or its licensors or contributors. ... Uncategorized. All farmers in Palampur grow at least two main crops; many are growing potato as the third crop. By multiple cropping farmers grow different crops on same piece of land. Modern farming technology is used to improve the wide types of production practices employed by farmers. Different types of cropping system. It is an another way of increasing the productivity of the land. In the southwest, intercropping, relay cropping and mixed cropping are still widely applied for the dryland due to the combination of sufficient farm labor and farmland shortage. Nevertheless, work on a suite of weed management techniques tailor made for long duration crops, such as cassava, is needed urgently. Why do farmers using modern farming methods need more cash than before? (2013) showed that the adoption of conservation tillage practices reduced carbon dioxide emissions, while also contributed to increases in soil organic carbon and improvements in soil structure with a number of other advantages that justify its wider adoption. This data comes, however, both from experimental field trials as well as from farmer's fields, and it is thus not necessarily representative of the entire organic farm population. Cropping and tillage systems have major impacts on potential soil erosion. Mixed cropping is a system of sowing two or three crops together on the same land. In principle, sequential cropping, where a second crop is grown after the harvest of a first crop, is a simple form of multicropping. In the coastal lowland of Kerala two crops of rice is grown per year because of: 1. high temperature in winter 2. adequate rain throughout the year 3. adequate irrigation facility 4. presence of water retentive clayey loam soil. Yields of second crop are often poor and unreliable, often because of pest and disease transfer. Sometimes known as “hedgerow intercropping”, No-till/strip till, nonirrigated, seven states. Rice is sown early or late in the cropping season. List of 220 + multiple choice questions and answers on Agriculture! Instructions. What is difference between multiple and duel cropping? What is the working capital required by the farmer using the modern farming methods? Then the excessive cultivation of soils that are row-cropped can create problems with soil structure. Individual species may be sown, fertilized, and harvested separately, Intercrops where blocked rows of each species are grown separately, Strips are wide enough for some plants within each block to behave as if in a sole crop, The interplanting of one species with a second species before the first crop reaches maturity, The very short overlap means competition between species is minimal. The major reasons for multiple cropping systems are to increase grain production and to maximize resource-use efficiency, which is facilitated by family labor (Zhou et al., 2007). In the northeast and the west, only one crop (maize, rice or soybean) can be sown annually due to temperature and precipitation limitations. They not only reduce soil nitrogen leaching (nitrates become immobilized in plant biomass), but also provide a relatively effective means of weed control. Multiple cropping areas decreased recently due to the shortage of rural labor and the development of the rural economy. Combining the higher yield from atrazine and the lower herbicide cost with atrazine treatments resulted in added grower income of $25.95/A in 2005. also cabinetmaker. e.g., (i) Multiple Cropping When more than one crop is grown on a piece of land during the year it is known as multiple cropping. â¦ Money is always required during production to make payments and buy other necessary items. Intensive: High inputs of labour or capital ususally small. Multicropping systems are among the most common agricultural methods in the Global South, particularly on small farms where practices are designed to produce subsistence for families with limited resources. most used combinations in mixed croppig are: wheat+gram, â¦ Improvement in living standard of farmers. Article shared by: . Table 1.8. Word forms: plural. These complex systems may include dual canopy crops where high-value plantation crops such as oil palm (Elaeis guineensis), coconut (Cocos nucifera), cocoa (Theobroma cacoa), or rubber (Hevea brasiliensis) are interplanted with annual species. Economic or social value, ease of cultivation, nutrient requirements, planting density and spacing, variety and type of plant, and other cultural factors influence the choice and arrangement of different species. On the other hand, modern farming makes use of modern equipment. The greatest negative consequence of cropping systems involving mainly row crops is soil erosion. The different crops on the same land can be cultivated in the different season. Multiple cropping systems are increasingly being used as a tool in modern agriculture. During winter, vegetables (e.g. Name any two methods to increase production in agriculture. (For instance. Answer: What is multiple cropping system class 9? Bohemia is called „Čechy“ in the Czech language. (a) It is the most common way to increase â¦ For example, combinations of rice (Oryza sativa) and other cereals or legumes may be found in higher-rainfall areas with a single extended rainy season such as southeast Asia. Corn yields from 236 university trials reported by the North Central Weed Science Society (NCWSS) between 1986 and 2005 showed that atrazine treatments resulted in an average 5.7 bu/A advantage (Fawcett, 2006). What is multiple cropping? Question: What Does It Mean For A Drink To Be Dry? There is large diversity in Chinese cropping systems including single, double and triple cropping (Fig. It is an another way of increasing the productivity of the land. However, within these categories the rates with which canopies establish vary. In contrast, conservation tillage is related with any system that reduces loss of soil or water (Manning and Fenster, 1983). It is important to understand that the main components of the soil environment include structure, texture, temperature, moisture, air, and nutrient availability and all of them need to be considered to maintain a proper soil structure (Carter, 1994). Between the Great Wall and the northern Huaihe River, the double-cropping system is dominant with two dryland crops annually, such as wheat–maize, wheat–soybean, or wheat–peanut. People in Palampur are able to grow three different crops because they have electricity and well-developed irrigation system. Some primary studies have observed slightly higher diversity of crops in organic than in conventional farms (Belfrage et al., 2005; Kragten and de Snoo, 2008; Weibull et al., 2003). Sowing of second crop before harvest of first crop reduces labor peaks at harvest. Enhanced productivity. It is the most common way to increase production on a given â¦ For example- Farmers in palampur grow atleast two main crops; many are growing potato as the third crop. Very Short Answer Type Questions. The objective of a tillage system is to provide a good seedbed, help control weeds, and modify the soil environment to make it as favorable as possible for corn growth while minimizing soil erosion. a, Verena Seufert, ... Tim G. Benton, in Agroecosystem Diversity, 2019. Learn more about multiple image reading, detecting multiple faces from multiple images There are nine production classes varying by geographic region, tillage type, and irrigation. (note : write the answer in points!!!) The most common sink sizes are 24, 30, and 33 inches. Is multiple cropping a modern farming method? Table 1 describes various types of cropping system ranging from the simplicity and uniformity of monocrops, where similar plants grow alongside each other simultaneously and sequentially from one season to the next, through to the multiplicity and heterogeneity of agroforestry systems where diverse plant types coexist within and between seasons. How loud can a human yell? But census data on livestock associations of organic farms are not available. cabinet maker. Crop rotations typically form an integral part of organic management, as sequential cultivation of different types of crops is used to suppress pests and diseases, to maintain soil fertility, and to prevent soil erosion and nutrient losses. Health concerns related to the direct consumption of cassava roots and pesticide residues need to be dispelled using recent qualitative laboratory analytical data. Crops are commonly sown in May and harvested from September to October. Even more challenging is the development of low residue herbicide formulations specifically for root and tuber crops that farmers directly consume at harvest. What is the first plague God sends? Multiple cropping- It involves growing two or more crops on the same farmland during the same cropping season. What are the requirements of multiple cropping? What is multiple cropping explain with example? Where corn yields are high and the crop residues are returned to the soil, the level of organic matter is also high. What is the difference between multiple cropping and modern farming method Class 9? Cassava is a long duration crop and varieties grown in the region take 12â18 months to maturity and these are commonly grown as monocropping and multiple cropping systems in Angola, Malawi, Mozambique, Zambia, and Zimbabwe. Fig. Such systems emphasize leaving varying amounts of crop residue on the soil surface. Includes Illinois, Indiana, Iowa, Minnesota, Missouri, Ohio, and Wisconsin. S.N. What are the advantage of using modern farming method? Quick Answer: How Do You Reuse Leftover Pasta? The growth of the second crop is often risky because of the limited amount of residual moisture. Sequential cropping (growing one crop after another in the same year) and intercropping are types of multiple cropping and include numerous different systems. These issues are explored in the following sections. If we did not use fertilizers then the some insects attack on the crop. Multiple cropping became more prevalent with the introduction of high yield variety seeds. Wheat–maize rotation or a relay cropping system is being replaced by spring maize per season in the northwest (Gansu and Shaanxi), or in the northern China Plain such as northern Hebei, Tianjin, and Beijing. Some of the more common crops grown in rotation with corn are oats, wheat, barley, soybean, sorghum, alfalfa, and numerous clovers and grasses (Farnham et al., 2003; Brummer, 2006). That means farming with the facilities of modern science and technologies. Inter-cropping aim is to increase the productivity from the unit area. Small farm families find the labor needs in multicropping to be both rewarding in food production and limiting as they attempt to scale up to commercial activity, and diverse systems address other social issues in the community. Weed management in cassava cropping systems is currently dominated by mechanical methods with manual hand weeding leading other methods. Restricted to crops such as sorghum, millet, rice, and pigeonpea, Crop composed of individual plants of the same variety of one species, Interactions occur between plants that are all at the same stage of growth. Even in the paddy fields, farmers often grow soybean and vegetable crops on the paddy ridges during the rice-growing season. China has a small farmland area per capita with the largest population in the world; hence the role of the multiple cropping systems to ensure food security is crucially important. (2015) showed that in 13% of studies examining yields of organic agriculture for annual crops organic systems had longer crop rotations than conventional systems (while the remaining 85% of studies had similar rotation lengths), while 24% of the 92 studies on annual crops included in their analysis did not use any crop rotation in the organic system. Asked by Wiki User. Given the importance of crop rotations for organic management and given the crop rotation requirements in many organic regulations, this appears like a small difference. Recently, a novel relay strip inter-cropping system of wheat–maize/soybean has been developing in the southwest which outperforms economically the traditional wheat–maize cropping system by 30% or more (Yong et al., 2012). It refers to the widespread adoption of high-yielding cereal crop varieties by farmers in many developing countries starting in the mid-1960s. About September, Is cycling 30 miles a day too much? Two characteristics, which dominate cassava systems and could be major consideration when designing weed management strategies, are the crop cycle, i.e., time to maturity, and the crop architecture. There are two main types of tillage, conventional and conservation. Tillage includes benefits in terms of its soil-loosening, seedbed-preparation, and weed-control effects. For livestock, some studies show that organic dairy farms often include more other species like chicken, dairy animals for slaughter, and pigs than conventional dairy farms (Sorge et al., 2016). The National Corn Growers Association in the United States represents more than 32 300 growers from 48 states and each year sponsors a corn yield contest.
