Companion Planting - Biodiversity; by Sustainable Farming Fund

  1. 1. Companion Planting – Biodiversity Workshop Notes Biological Husbandry Unit Lincoln University June 2004The tendency in market gardens is to plant large areas of single species. This is contrary to some ofthe principles of sustainable agriculture and represents a lost opportunity in terms of the beneficialinteractions that can exist between crops of different species. Home vegetable gardens on the otherhand usually have many crop species growing in close proximity but they are usually not veryplanned. The practice of growing two or more species together to derive some strategic benefit iscalled “intercropping”.A subset of intercropping could be described as companion planting though this term may imply aless scientific basis. Companion planting is highly related to the concept of mutualism. The mutualbenefits accrued to two or more species interacting with each other has long been associated with acreative design for species on Earth (animal examples include fish living in the gills of other fisheating parasites and plover birds picking between the teeth of crocodiles). In the 18th and 19thcentury there was, however, increasing focus on the competitive nature of interactions betweenorganisms perhaps peaking with Charles Darwin‟s Origin of the Species, which accentuated theconcept of survival of the fittest.Interest in mutualism still continued with an important caveat from the rational scientific perspectivethat mutualisms actually still involved each partner acting in its own self interest, not through someselfless motivation.The study of mutualisms in crop science has only begun at any great level since the 1970‟s and inmany cases is yet to come through and confirm or falsify beneficial relationships that have beenproposed between many crop plants. Some of the confirmed combinations can be explained in quitesimple means as described below but many have been derived from intuition or non-scientificmethods.Gause‟s Law (“that two species cannot occupy the same niche at the same time without excludingthe other”) could be seen as running contrary to the concept of companion planting/intercropping butin fact the two or more “mutualistic” species can occupy different niches even in the same area.Examples of this are also given below including the fact that the root zones and above groundarchitecture of plant species can be radically different allowing close spacing and maximumutilisation of resources.
  2. 2. Combinations of plant in intercropping can be beneficial in terms of reducing pests and diseases, outcompeting weeds, maximising resource utilisation, reducing input requirements and providingimproved environmental condition for one or more of the species involved.Benefits Related to Pests, Diseases and WeedsA second plant species may cause reduced pest or disease levels through one or more of thefollowing mechanisms…Disruptive Crop: The pest or disease progress through a crop is impeded by the physical presenceof another (non-host) crop - for instance affecting the flight of insect pests, reducing the spread ofdisease spores and even providing a physical barrier to vertebrate pests. This is sometimes called the“flypaper” effect.Resource Concentration: Conditions for epidemic problems of pests and diseases can be reducedby having a lower concentration of host plants so there is lower propensity for spread from plant toplant. Intercropping is one way of reducing host plant density while still yielding the same or moreproduce per unit area.Trap Cropping: Similar to the disruptive crop idea but in this case the pest or disease is triggeredby and may even attack the trap crop. The trap crop may need to be removed or incorporated into thesoil before a pest or disease has time to multiply.Natural Enemies: Some plants may benefit biological control agents (natural enemies) of the pestsor diseases. The most common examples are ones that provide food (e.g. flowers or alternative prey)and shelter (for day to day activities or overwintering).Benefits for Weed Management: W Some intercrops may be effective at smothering weeds orreducing weed germination. In many cases this can be simply through providing a greaterpercentage of soil cover than a monoculture and/or providing that cover more rapidly. In some casesa plant species may produce allelopathic chemicals that inhibit the growth of many weed species e.g.some varieties of cucumber and squash.Note: Some intercropping designs will prevent effective mechanical weed control. Make sure thatchosen designs fit with appropriate methods of weed management including paying attention to thetypes of weeds present. For example perennial weeds such as twitch/couch grass may be able togrow amongst an intercrop without adequate control leaving an increased problem with this weedafter these crops.
  3. 3. Benefits in Improved Utilisation of ResourcesSunlight:  The aim can be to maximise the amount of sunlight per unit area that is captured byplants and converted into carbohydrate energy and harvestable yield. There can be differences inplant architecture, light level tolerances, different timing of presence and general ability to be plantedclose together (the last factor due to some of the other resource utilisation factors or pest and diseaseeffects). Mostly this is thought of on a spatial scale, with the object being to minimise the amount ofdirect light that reaches the soil (i.e. to maximise the amount of light utilised by the plants) but thetemporal scale can be very important. An undersown or oversown crop will utilise solar energyhighly efficiently after the harvest of a main crop – even if this is just a catch crop, it will provideorganic matter for feeding soil microbial activity and addition to soil humus.Note: In some cases, a reduction in the amount of direct sunlight reaching the ground can be seenas a negative aspect. This is the case in some orchards and vineyards where heat build up in the soilduring the day is required to reduce the risk of frost overnight that might otherwise affect sensitivebuds or flowers.Aerial Space: Related to the sunlight capture, this is simply the ability to fit more plants in to an area of ground bytaking advantage of different “canopy” levels, plant architecture and timing  of crop growth.Root Competition: RCompetition for nitrogen, mineral nutrients and water may be less between plants of different speciesbecause of difference in rooting depth or zone, rooting form or time that the roots are utilisingresources.Water:  Extra ground cover from some interplanted species may help conserve soil moisturelevels.Note: In some cases intercropping may increase the per-hectare water and nutrient requirement asoccurs for some orchard understoreys.Catch Crops: Some catch crop plants may be interplanted with a cash crop to “capture nutrients” from deeper inthe soil and effectively bring them up to the surface. Or the catch crop may simply reduce theamount of nutrients susceptible to leaching, the latter usually meaning an advantage for a subsequentcrop after the catch crop is incorporated in as a green manure.Soil Condition: ▒Soil condition deteriorates when there is a lack of vegetation. Part of this is exposure of the soilsurface to drying out and damage from rain and watering. The presence of roots is also anotherfeature of vegetation that improves soil structure by physically pushing through the soil, bypromoting soil biological activity through the leaking of “nutrients” and by old roots dying,
  4. 4. decomposing and forming soil organic matter including humus. Intercropping can improve the soilcover spatially (tighter combination of vegetation covering the soil) and temporally (an undersown oroversown crop may remain after harvest to continue to provide soil cover.Cultivation: CThe requirement for cultivation can be reduced simply by the outcompeting of weeds as mentionedabove. In some cases a subsequent cash crop, catch crop or pasture can be sown at the same time orbefore the harvest of an initial crop thus eliminating the requirement for cultivation after harvest ofthe original crop.Edge Effects: ┐Many of our crop plants are adapted to being on the edge of a forest or in a forest clearing. These areexamples of botanical edges. Intercropping can provide an increased number of edges and thereforeopportunities of crop plants to take advantage of, for instance, a sheltered environment incombination with sufficient sunlight. Also includes some plants providing a “climbing frame” forother plants e.g. corn for beans.Nitrogen Fixation Many intercropping combinations include a legume component. This may contribute availablenitrogen to the soil or at least reduce the amount of nitrogen that needs to be applied or utilised fromthe soil for a given yield. Since nitrogen is often the most limiting element for crops, it makes senseto contribute to the pool of this nutrient.Yield: YThe crop yield per unit area will often be increased through the strategic use of intercropping. Thereare many variations to this. In some cases the aim is to improve the yield of the main crop from thebeneficial effects of the intercrop species and in other cases the aim is to have a combined yield thatis greater even though the yield of each individual species may be less than if they were grown bythemselves over the same area. Yield per unit area can be very important in countries with limitedland area available or for maximising the yield in particular areas of interest such as tunnelhouses,microclimates or space-limited farms. The Land Equivalent Ratio (LER) can be used to portray theyield advantage of an intercrop. The LER is the number of hectares of monoculture crops required tomatch the production of the intercrop on one hectare. An example is the calculation for a BHUexperiment on squash, bean and corn which gave an LER of around 1.7 for two of three densitiestested (for one hectare of intercrop, there was the equivalent production to planting approximately0.6 ha of squash, 0.2 ha of bean and 0.9 ha of corn).Note: Harvesting is more complex and mechanical harvesting may be precluded.The major cost in western countries is often in the harvesting. The amount of production per hectareis not usually a crucial factor with market garden vegetables. Planting should be such that it stillfacilitates harvesting. Strip cropping or at least planting in rows can allow more efficient harvestingif required. In some cases, mixed grains may be able to be harvested mechanically together andseparated later.Bees: B Flowers provide fodder for bees for potential extra honey harvest and/or improvedpollination of intercrops or other crops.
  5. 5. Aesthetics: Intercropping tells a story of its own complexity that attracts a human audience. A market gardencan benefit from such combinations which in some cases may also be visually striking in colourcontrast, plant form contrast or simply be more pleasing to the eye with less soil exposure and areduced “harshness” crop rows.Conservation Values: Conserv There can also be non-commercial benefits of conservation of native(or other important) flora or fauna from the planting of native and some introduced plant species.Intercrop DesignIt is important to determine what factors might be involved in the mutual or one–way benefits (andnegative effects) between intercrop species as the benefits will tend to vary between environments,soil types and style of farming. Once we have an understanding of the interactions, we are morelikely to be successful in introducing intercropping systems into new areas. Nevertheless there willstill be a requirement for trialing crop mixtures and optimising the design for a particular farm beforerelying on them too heavily.One approach to assessing intercrop design is to assign codes to the interaction between two species.Namely does one plant species benefit „+‟, suffer „-‟ or not get affected „0‟ by the planting of anotherparticular species beside it. The effect of the first plant on the second plant is then also assessed. Apaired code is then given (if one crop is the main or original crop it is represented first and asecondary crop represented second)…-- : Both crops are negatively affected by the interplanting0- : The first crop neither benefits nor suffers but the second crop suffers-0 : The second crop neither benefits nor suffers but the first crop suffers00 : Both crops are neither positively nor negatively affected by the interplanting-+ : The first crop suffers but the second crop benefits+- : The second crop suffers but the first crop benefits0+ : The first crop neither benefits nor suffers but the second crop benefits+0 : The second crop neither benefits nor suffers but the first crop benefits++ : Both crops are positively affected by the interplantingThis method is described in Mollison (1998, p.62) with examples given related to treecrops. This fitswith the main origin of this method, which is interspecies forestry design. The method can beapplied to vegetable crops though there is a higher degree of complexity of plant form, crop timingand other factors. One of the major uses of this method is to design to accentuate the positives,eliminate the negatives by using a Mr. In Between which has positive or null effect between itselfand neighbours on either side (there may have been negative interaction between the neighbourswithout the in between plant) [again see Mollison (1988, p.62 for an example)].It is not just a case of fitting as many species as possible into a crop mixture and waiting for stabilityand productivity. The number and magnitude of the beneficial connections (balanced with thenumber and magnitude of negative connections) between species chosen is of greater importancethan the number of species. In many cases an intercrop of two or three species is a highly efficient
  6. 6. system requiring little outside input. Care is still warranted in case pest/disease or other issuesinterfere with this normally successful combination.Applicability of Intercropping ExamplesThe examples dealt with here are broadly relevant to many New Zealand conditions. It should benoted though that there are many international examples of intercropping practice that are mostlyapplicable to a tropical setting. The construction of food forests is a popular concept withinPermaculture but as discussed below under „Orchards‟, there needs to be quite a different approachtaken to this concept in temperate as compared to tropical regions.Where the difference in site is not as dramatic as tropical versus temperate, experimentation is stilladvisable to derive optimum combinations, planting design and spacings for the new area andenvironment. In many cases intercropping designs are based around particular pest species whichmay not even occur at the new site.INTERCROPPING EXAMPLESBroccoli with Mustard   W   R   ▒ C ┐ Y B Mustard may be grown around areas of broccoli to reduce pest levels in the broccoli. Mustard acts asa trap crop for the cabbage flea beetle and if allowed to flower will improve the survival andeffectiveness of parasitoid wasps for the control of caterpillars (diamond back moth and whitebutterfly). The two species of the same family occupy different root zones (mustard is deeperrooting) so competition is reduced. Mustard can be grown as a crop for salad leaves or the seed itselfor simply turned in as an effective green manure. Mustard species can also be effective in trappingand reducing the levels of plant parasitic nematodes.Cabbage and Tomato or aromatic plants   W   R   ▒ C ┐ Y B Tomato emits odour that either repels diamond back moths (Plutella xylostella) or masks thecabbages from the moths. The odour from celery, dill and rosemary is also thought to interfere withcabbage location by this pest species and white butterfly.Broccoli and Lettuce    W   R   ▒ C ┐ Y Planted at the same time in alternating rows, the lettuce is ready faster and takes advantage of thespace and other resources available before the cabbage has formed a tall canopy. This also helpsreduce the potential for weeds.Carrots, Beets, Onions    W   R  ▒ C ┐  Y 
  7. 7. Planted in single species rows, these crops do well in each others presence. The onion and carrothelp mask from or repel plant pests such as carrot rust fly. The beets provide shelter for the soilreducing weed issues and providing habitat for beneficial insects such as predatory ground beetles. Note: European research has shown that the carrot rust fly deterrence is effective primarily in thefirst flight of this pest though subsequent flights are likely to have reduced problems as long as onionwere present from early in the season.Salad Vegetable Polycultures    W   R   ▒ C ┐  Y B It is now common to grow mixtures of salad species such as a mesclun mix. These can be cut inmixtures so scattered random placement of seed is workable. In many cases the plants will have areasonably similar growth form so the advantage of mixing is for aesthetics, rate of growth andreduced pest and disease potential through plant diversity. Some combinations can be planned suchas at the Biological Husbandry Unit (BHU), Lincoln University where upright edible amaranthusprovides a frame for the nitrogen fixing snowpea and mixed in with these two is the shade tolerantshingiku (Japanese edible chrysanthemum) which is relatively pest free and may reduce pest levels inthe other crops through masking or repellant effects.Corn, Squash and Bush Beans    W   R   ▒ C ┐  Y B This is a long-standing traditional intercrop combination of species in the Americas. One of thenames for the combination is the Aztec trilogy. The North American Indian methods of planting thiscombination along with sunflower are discussed in detail in the first web link given in the resourcessection. Some of the mechanisms for the high combined yield per hectare are the differences in plantarchitecture and maximising sunlight use, nitrogen fixation from the beans, corn providing structurefor beans to climb, shading of the soil by squash conserving soil moisture, reduced pest problemsfrom diversity and disruption of insect flight by the corn plants, the squash vines inhibiting raccoonmovement and differences in root zones and nutrient requirements. The BHU has successfully usedthis mixture.Clover Understoreys   W   R  ▒ C ┐  Y B White or red clover can be sown at the same time (or clover oversown once a slow growing cropspecies is sufficiently established) with many horticultural and broadacre crop species such ascabbage, cereals, sweetcorn and maize. Here the intention is to allow nitrogen fixation that willbenefit the cash crop and/or subsequent crops. There may also be benefits of extra weedsuppression, lower weeding requirement and improved habitat for predatory ground beetles and otherbeneficial insects and spiders.Industrial Hemp and various species    W   R   ▒ C ┐ Y Industrial hemp is currently a restricted crop requiring police permission for trial growing. It islikely to become a reasonably significant cash crop for its fibre as well as seed (including theproduction of high value health products from the seed oil. The emission of plant chemicals fromhemp has long been associated with reducing pest and disease levels in crops. It can apparentlyreduce caterpillar damage in a variety of crops including cabbage with which it was oftentraditionally planted as a border plant. Any effect on diseases requires further elucidation. It can beused to provide shelter for late summer crops with the hemp rapidly growing to two or three metresin height. Hemp is very deep rooting
  8. 8. In China a corn and summer squash intercrop is practiced in some regions with self sown industrialhemp allowed to establish in the shady environment. After the corn and summer squash areharvested, the hemp is allowed to rapidly grow and produce a seed crop (harvested for its oil). Anadditional practice can be to oversow with clover as the hemp starts to lose leaf cover giving some ofthe same benefits as discussed in the oat and clover intercropping example below.BROADACREVarious Crops with Clover   W   R  ▒ C ┐  Y B As detailed above it is possible with several crops including cereals, sweetcorn and maize to sowwhite or red clover with the cash crop. With some crops such as linseed there is the opportunity tosow not just clover but a whole pasture sward with this fast growing cash crop. The pasture swardestablishes in the shade of the linseed and then, following grain harvest, it rapidly grows to a stockcarrying condition. A cultivation is saved and there is no lag between grain crop and pastureestablishment.Oats oversown with Clover   W   R  ▒ C ┐  Y B As heads start to form in the oats, the farmer oversows with clover, which establishes well in thepartial sunlight. After oat is harvested as forage, the clover will grow rapidly. Advantages of thissystem are improved clover establishment, faster turnaround to harvesting a second forage crop,nitrogen fixation by the clover, essentially replacing that used by the oats, no cultivation requirementafter the oats before planting the clover, and maximising sunlight utilisation during head formationand after the oats have been harvested.ORCHARDSApple Trees and Umbelliferous Understoreys   W   R   ▒ C ┐ Members of the Apiaceae (formally Umbelliferae) or carrot family have small open flowers suitablefor providing nectar and pollen to beneficial insects with short probosci including parasitoid waspsand hoverflies. Such plants have been used as understorey plants in apple orchards to providebiological control of codling moth and leafroller caterpillars through the boosted action of parasitoidwasps (leaf roller control is more effective than codling moth control as the codling moth caterpillaris protected for much of the time within the apple). The carrot family member used successfully atthe Biological Husbandry Unit (BHU) at Lincoln University is cow parsley (Anthriscus sylvestris).The cow parsley offers a range of benefits including – a wide season of flowering providing food forbeneficial insects, perennial growth habit requiring little maintenance, it outcompetes grass speciesthat would otherwise reduce apple yields, it eliminates need for herbicide strips or mulching, itprovides a habitat for beneficial insects, its tap roots do not compete strongly with apple tree roots, itincreases rate of leaf litter decomposition (nutrient cycling and disease prevention benefits) and it
  9. 9. traps black spot fungal spores that are shot up in the spring from the fungus overwintering in leaflitter. Alternatives or additions to cow parsley include wild carrot, wild parsnip, dill and corianderbut they do not have them same protracted flowering period or persistence. Wild flower strips ofmember of other plant families can be beneficial including yarrow, chamomile, borage, clover,chicory and cornflower. Other understorey companions that may be useful include nasturtium (weedsuppressive, edible flowers, leaves and seeds, possible codling moth limiting through providinghabitat for natural control agents) and chives (grow okay in the semi shade and may provide someprotection from apple blackspot).Food Forests    W   R   ▒ C ┐  Y B  ConservA popular concept among Permaculture is that of Food Forests. A collection of productive trees,shrubs and various herbaceous perennials and understorey plants are planted together to resemble acomplex forest ecosystem yet still be productive. Examples of Food Forests abound in developingtropical countries where they suit a subsistence lifestyle and provide a diverse diet over the wholeyear and display good resilience to outside factors such as droughts, storms and pests.There are some examples of Food Forests in sub tropical parts of New Zealand but the economicefficiency requires consideration as harvesting and maintenance requirements may be more difficultper unit of production. A further consideration in New Zealand is that the usual design of food forestis one of dense planting of a high variety of species. Most temperate fruit and nut species will not dowell in dense and shaded planting especially with regard to fungal and bacterial diseases favoured bythe likely humid conditions (tropical species are more adapted to this type of condition). Atemperate Food Forest needs to have better airflow, more distance between trees and the sameamount of food productivity per unit area will not be possible.

We have been intercropping sorghum with legumes planted in row of zaipits.Why grow beans? Being legumes, bean crops can improve soils by converting nitrogen from the airinto forms that crops can use. The crops we are working with are quite tolerant of dry conditions andproduce vines that cover the ground, protect6ing it from the intense tropical sun and creating anenvironments in which soil microorganisms, can thrive. Moreover, the legumes provide the farmerwith a harvest of dried, edible beans.What are zai holes? The zai system originated in West Africa as a way to cope with drought and hardencrusted soil. Drought tolerant grain crops such as sorghum or millet are planted in pits about 12inches, 6 inches deep. With the excavated soil thrown to the downhill side, the pits act as tiny watercatchment basins, making maximum use of what little rainfall is received. Several handfuls ofmanure are traditionally placed in each pit, concentrating nutrients near the crop roots.Have we seen any benefits? The results we have so far are from year one of a sorghum-legumesintercropping strategy within the zai system. Most of the legumes we have tried have grown verywell, but cowpea produced the most dried beans.It increase total grain production from 400 kilograms per hectare when grown sorghum alone toabout 1400 kilograms per hectare when grown together with cowpeas.It also increased soil nitrogen as well as nitrogen taken up by the sorghum plants.All of this is very encouraging from the perspective of the smallholder farmer, because it means theyhave a way to improve their soils while greatly increasing food production.
  11. 11. NATURAL SOLUTIONS in Africa by Using Companion PlantingAcross East Africa, thousands of farmers are planting weeds in their maize fields (CompanionPlanting). Bizarre as it sounds, their technique is actually raising yields by giving the insect pestssomething else to chew on besides maize.It is better than pesticides and a lot cheaper, said Ziadin Khan, whose idea it is.And it has raised farm yields by 60-70 Percents.In East Africa, maize fields face two major pests, and Khan has a solution to both. The first is aninsect called the stem borer. True to its name, it s larvae eat their way through a third of the regionsmaize most years.But Khan discovered that the borer in even fonder of a local weed, napier grass. By planting napiergrass in their fields , farmers can lure the stem borers away from the maize and into a honey trap. Forthe grass produces a sticky substance that traps and kills stem borer larvae.The second major pest is Striga, a parasitic plant that wrecks 10 billion dollars worth damage onmaize crops every year, threating the livelihoods of one hundred million Africans.Weeding Striga is one of the most time consuming activities for millions of African women farmers,says Khan.But he has an antidote: another weed, called Desmodium. It seems to release some sort of chemicalthat Striga does not like. At any rate, where farmers plant Desmodium between rows of maize, Strigawill not grow.Khans cheap fixes for Striga and stem borer are spreading like wildfire through the fields of EastAfrica.Trials on more than 2,000 farms are finished. It is out of our hands now, says Khans boss HansHerren , who is the director of the International Centre for Insect Physiology and Ecology in Nairobi.The ideas are being taken up by framers in countries such as Ethiopia where we have never worked.Khans novel way of fighting pests is one of the host of Low-Tech Innovations boostingproduction by 100 percent or more on millions of poor Thirds World farms in the pastdecade.This Sustainable Agriculture just happens to be the biggest movement in Third World Farmingtoday, dwarfing the tentative forays in genetic manipulation.It seems peasant farmers have a long way to go before they exhaust the possibilities of traditionalagriculture
