It also includes the growing of a cash crop with a cover crop or other non-cash crop that provides benefits to the primary crop or to the overall farm system. Ostlie suggested producers who want to intercrop test it first in a small farm trial on their farm. 8. It is practiced in most crops whether direct seeded, transplanted, or grown from vegetative planting materials, both in monocropping and multiple cropping. Row planting as applied in conventional horizontal farming or gardening is a system of growing crops in linear pattern in at least one direction rather than planting without any distinct arrangement. Plants such as garlic, pepper, onion and basil repel some plant pests and can be planted between tomatoes, carrots or any other crop, as long as all plants have sufficient sunlight and space to grow properly. Date: January 27, 2021 Intercropping refers to the agricultural practice of growing two or more crops together in the same field. Modernization of farming equipment has changed our farming practices into what they are today, which is largely mono-cropping. Relay Intercropping/Relay Cropping: Growing of two or more crops simultaneously on the same piece of land during the part of life cycle of each. Second, crop mixtures frequently have lower pest densities, especially of insect pests. Technologies of crop growing and harvesting: diversity of attitudes. to rotate crops, or use intercropping or strip cropping. Intercropping systems require additional management. Alley Intercropping/Alley Cropping: Food crops are grown in alleys shaped by hedge or shrubs or trees. Strip intercropping is the growing of two or more crops together in strips wide enough to allow separate production of crops using mechanical implements, but close enough for the crops to interact. There were other trials done in Ames using winter wheat for harvest and as a cover crop. Examples of the relay cropping system are cotton and corn or chickpea and upland rice. Intercropping also poses a special problem for crop rotation. Crop rotation Example Planting maize one year, and beans the next. If plants from two families are mixed in the same bed or field, however, achieving a substantial time lag before replanting either of those families may be difficult. Suppose, for example, that a farm grows an acre each of tomato, squash, broccoli, and mid-season lettuce. Cover crops can also be intercropped with one another. Therefore, there is a minimum temporal overlap of two or more crops. For example, a second crop can be planted into an existing crop when it has flowered (reproductive stage) but before harvesting. For example, radishes are often planted with carrots. Strip intercropping: Growing of two or more crops together in strips wide enough to permit separate production of crops using mechanical implements, but close enough for the crops to interact is termed as strip intercropping. Sustainable Agriculture Research and Education, by Charles L. Mohler and Kimberly A. Stoner. This means changing the type of crops grown in the field each season or each year (or changing from crops to fallow). © Copyright 2019 Apex Publishers or related companies. In this article, I will commence with the aid of advising that when you set up a banana plantation, do not leave the spaces in … It may do little, however, to increase resource capture by the crops, unless alternating strips are close together. Thus, intercropping requires extra care and effort in planning and maintaining a viable crop rotation. Intercropping: Why Some Farmers Try Something Different Intercropping is defined simply as growing two or more crop types on one field. The second crop is planted after the first crop has reached its reproductive stage of growth but before it is ready for harvest. Sometimes there are perennial species with annual crops grown amongst them, say perennial garlic and basil with annual tomatoes. Doing this successfully requires a bit of additional focus on companion planting. Instead of devoting a w… Intercropping continues to gain attention of U.S. producers hopeful of growing two cash crops simultaneously on the same ground to pull in greater overall return from the … Multi Storied Intercropping/Multi Storied Cropping: Growing of two or more crops of various heights around precisely the same field in the same moment. Mixed intercropping systems can be very complex with a number of crops produced together. Intercropping is an all-encompassing term for the practice of growing two or more crops in close proximity: in the same row or bed, or in rows or strips that are close enough for biological interaction. List of Disadvantages of Intercropping. Row intercropping is the cultivation of two or more crops simultaneously on the same field with a row arrangement (See Figure 8.1). With that definition, it’s easy to see why this is an attractive option for gardeners with limited space. Row intercropping involves the cultivation of different crops … Seeds or other plant material can be obtained from other farmers, on local markets or from specialized seed producers. The practice of intercropping has actually been around since farming began. The secondary crops can provide shelter and even protect the primary crops. Click on the following topics for more information on intercropping on organic farms. This practice is typical of slash-andburn agriculture, which relies on cutting and firing. Maize and legumes in alternating rows (serc.carleton.edu) It is a kind intercropping where different crops are grown at the same time in the same piece of land with a distinct row arrangement. A simple rotation would put each of the crops in a different year, with a three-year interval before a crop is repeated on the same bed. Intercropping includes the growing of two or more cash crops together. Intercropping also allows you to grow cash crops or any crop that will actually supplement the primary crop in some way. For an intercropping scheme to be useful, it should improve the overall economics of the farm. There are two types; contour strip cropping and field strip cropping. If full rates of each crop were planted, neither would yield well because of intense over-crowding. The crops that may grow tall and have a tendency towards excessive growth should be discouraged. Interplanting or intercropping basically involves using 2-3 crops in the same planting area, at roughly the same time, for some beneficial purpose. Intercropping is the technical term for the practice of planting two or more crops in close proximity. ROW INTERCROPPING ROW INTERCROPPING is the growing of two or more crops at the same time with at least one crop planted in rows. 3. Note that some consequences of intercropping—such as better or worse weed control, or difficulties in timing planting or harvest—may not show up in a single test year. USDA is an equal opportunity provider and employer. You can sow turnips with other crops, too, but keep in mind that at around 55 days to maturity, they take longer than most others on this list. Growing Crops two crops may also be possible if there are two rainy seasons, or if there is enough moisture left in the soil to grow a second crop.

Relay intercropping is practiced in regions where the growing season is too short to permit two sequential crops. It also includes the growing of a cash crop with a cover crop or other non-cash crop that provides benefits to the primary crop or to the overall farm system. A new intercropping idea should be tested first on a relatively small area. Yields for the wheat fields came in around 57.2 bushels per acre in 2018 and 30.1 bushels per acre in 2019. Seeds or other plant material can be obtained from other farmers, on local markets or from specialized seed producers. height and width of the plant. Cover crops can also be intercropped with one another. Introduction to Intercropping on Organic Farms, Benefits and Limitations of Intercropping, Integrated Pest Management on Organic Farms, Plant Disease Management for Organic Crops. This type of intercropping is ideal for shade loving plants like groundnuts and cowpeas. This will allow evaluation of whether it fits into the overall management system and whether benefits outweigh extra costs, labor, or yield reduction. SARE Outreach operates under cooperative agreements with the University of Maryland to develop and disseminate information about sustainable agriculture. Intercropping is good for the primary crops. Mono-cropping is planting only one … Principles of intercropping Intercrops should occupy a secondary place in the orchard, primary consideration being given to the perennial fruit trees. The goal is to get the interplanted crops to support each other’s growing habits, so you get a better result in the garden. This site is maintained by SARE Outreach for the SARE program and is based upon work supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture, under award No. Intercropping is an agricultural practice in which two or more crops are grown together in the same field. It is often used where fields are relatively small and field operations involve mostly manual labor. Beans Many gardener’s introduction to intercropping is through the three sisters method : planting corn, beans and squash together in the same plot. Mixed cropping, companion planting, relay cropping, interseeding, overseeding, underseeding, smother cropping, planting polycultures, and using living mulch are all forms of intercropping (see glossary at the end of this chapter). If, however, the lettuce and tomato are grown together (see the next section), crops would be separated by only a two-year interval, which may be insufficient to keep some diseases under control (see Appendix 3). Beans. Intercrop in Banana. Intercropping includes the growing of two or more cash crops together. This occurs both because the mixture confuses the insects and, if the mixture is chosen carefully, because the mixture attracts beneficial predators. Growing Crops two crops may also be possible if there are two rainy seasons, or if there is enough moisture left in the soil to grow a second crop. intercropping produces healthy crops Growing a variety of crops together minimizes pest problems and makes efficient use of soil nutrients. Consider including a pulse crop in the intercrop, as pulses fix nitrogen and help to improve soil fertility and soil structure. Another take on intercropping is to sow or plant between vegetables whose spacing and/or leaves naturally allow plenty of light to reach the ground so that seedlings of a later-season crop can find their feet while the earlier crop is in its final weeks of growth. No part of this content or the data or information included therein may be reproduced, republished or redistributed without the prior written consent of Apex Publishers. Field strip cropping has strips with uniform width that follows across the general slope of the land. This is to ensure your plants aren’t hoarding resources, or attracting all the wrong insects. In intercropping systems, it is an advantage if the different crops in the mixture have different maturity dates, with different times of peak demand for nutrients, water and sunlight, thereby reducing competition. All rights reserved. Finally, intercropping may allow more effective management of cover crops. 1. Meanwhile, soybean yields came in at 16.3 and 33.0 bushels per acre in the double-crop … Intercropping: Examples- Planting alternating rows of maize and beans, or growing a cover crop in between the cereal rows. Advantages of intercropping fall into three basic categories. When two or more crops are combined in a field, plant densities need to be adapted to maximize yields. First, an intercrop may use resources of light, water, and nutrients more efficiently than single crops planted in separate areas, and this can improve yields and income. While intercropping involves the planting of more than one crop on the same piece of land at the same time, there are different methods of maximizing yield from this type of farming. Almost any type of crop or combination of crops can be used for intercropping. These are the basic four methods commonly employed. USDA is an equal opportunity provider and employer. Strip intercropping is ideal for vegetables. The onion and carrot example makes … They often call for careful timing of field operations, and they may necessitate special interventions to keep competition between the intercropped species in balance. Intercropping: The method of growing two or more crops simultaneously on the same piece of land (field) is called intercropping. Use of this site is governed by our Copyright Policy, Terms of Use Agreement and Privacy Policy. The principle of intercropping is opportunism. As explained in chapters 2 and 3, this is critical for management of diseases and, to a lesser extent, insects. When two or more crops are cultivated in an intercropping system, each crop should have adequate space, to maximize cooperation and minimize competition between the crops. Another of the intercropping techniques is alley cropping. People noticed that planting either tops or roots in turns prevents soil erosion. When you stop to think about it intercropping li… Examples of mixed intercropping of annual crops are the practice of growing corn, bean and squash in Central America and forage sorghum with silage corn in Oregon. Consider including a pulse crop in the intercrop, as pulses fix nitrogen and help to improve soil fertility and soil structure. Relay Inter Cropping – Growing a second crop is planted into an existing crop when it has flowered … To accomplish this, attention should be paid to the specific local conditions (climate), the choice of crops, the arrangement of crops in space and time, the plant density, maturity dates of the different crops, plant architecture, and spatial arrangements. Intercropping, on the other hand, is a fancy word for planting two vegetables in the same space. Contour strip cropping follows a layout of a definite rotational sequence and the tillage is held closely to the exact contour of the field. With alley cropping, you plant crops in rows but each row is a different type of plant that benefits the rows around it. Choose crops that are locally grown and well adapted to the climatic conditions. The productivity of row intercropping is influenced by the specific combination of crops, their spacing, and planting dates. Sometimes they involve annual grains and vegetables, such as the mixed intercropping classic of corn, beans and squash. Planting crops in alternate rows or strips greatly simplifies management and captures some of the benefits of intercropping for pest control. Various approaches in agriculture developed thousands of years ago even without a scientific background. Cabbage grows in the part shade of taller rapini going to seed. It is also commonly practise in orchard and plantation crops. Crops that root deeply such as parsnips, carrots and tomatoes, can be intercropped with shallow vegetables such as broccoli, lettuce and potatoes.Fast growing plants, like spinach, can be tucked in around slow maturing plants like corn. You can plant early crops that will be removed from the garden alongside late-season crops. Almost any type of crop or combination of crops can be used for intercropping. A mixture of crops with different growth forms or timing of development may make cultivation and use of mulches more difficult and less effective. This type of intercropping is common in intensive subsistence systems, especially in subtropical and tropical areas of the world. In farms grown to perennial crops, annual crops like corn, rice and pineapple are commonly grown as intercrop between the rows of the main crop. In other words, while one vegetable is still filling out the crafty gardener sneaks in an additional crop that's long gone before the main crop needs its space. 7. Row intercropping involves planting more than one crop simultaneously, with at least one of the crops planted in a row. With intercropping, the two crops may have a synergism where one crop helps the other to give a better return on investment than when either are grown alone, according to CREC. 2019-38640-29881. The advantages of intercropping, however, do not come for free. One fundamental principle of crop rotation is the separation of plant families in time. It is easier to control pest outbreaks in one strip as this method ensures that crops of the same family are not too near to each other. Some vegetables can share space amicably. This suits a slightly larger garden than mixed cropping. Many people don’t think of growing beans next to or underneath their tomato plants, but it’s … A crop mix that works well in one year may fail the next if weather favors one crop over another. Intercropping: Examples- Planting alternating rows of maize and beans, or growing a cover crop in between the cereal rows. Intercropping has four general spatial arrangements. In designing an intercropping system, it is useful to pay attention to differences in plant architecture between the crops given that different crops may have a different architecture, i.e. Inga alley cropping has been proposed as an alternative to the ecological destruction of slash-and-burn farming. Root and tuber crop such as elephant foot yam, greater yam, cassava, spice crop like turmeric,ginger and other, vegetable and meditional and aromatic plants can profitably grown both at the young and old stages. Let’s get some basic definitions out of the way. The best crop combination tested in this experiment was canola-pea, which overyielded 100% of the time under conventional management. Poor Yields Intercropping can lead to poorer yields. Relay intercropping reduces temporal overlap in harvesting different species, but the second crop must be tolerant of the shade of the first one. Mixed intercropping or mixed cropping is the growing of two or more crops at the same time with no distinct row arrangement. Consider growth rate above and below ground when interplanting flowers and vegetables. Relay intercropping describes a cropping pattern in which the life cycle of one crop overlaps that of another crop. There is mixed intercropping, no distinct row arrangement; strip intercropping, growing crops in strips wide enough to separate them, yet narrow enough to allow interaction between them; relay intercropping, growing two or more crops during differing parts of their life cycles; and row intercropping, at least one crop is planted in rows. Types of Intercropping . There are four types of intercropping: Mixed intercropping is the cultivation of two or more crops that are randomly distributed rather than grown in rows. Perennials also work well with other perennials. Mixed intercropping ensures that the ground is covered, and therefore weeds are suppressed. Mixed intercropping: is defined as growing two or more crops at the same time with no distinct row arrangement. The purpose of this chapter is to outline some of the basic principles for using intercropping successfully and to relate these to the principles of crop rotation detailed in the rest of this manual. Examples of intercropping strategies are planting a deep- rooted crop with a shallow-rooted crop, or planting a tall crop with a shorter crop that requires partial shade. Aonla based intercropping system: In Canada, research showed increased production per land area by growing together soybean and corn … Choose crops that are locally grown and well adapted to the climatic conditions.
