| Umbrohud võistlevad kultuurtaimedega toitainete ja vee pärast ning muudavad kultuurtaimedele sobivat mikrokliimat. Kuid umbrohud suurendavad ka bioloogilist mitmekesisust ja on toiduks paljudele kasulikele putukatele. Umbrohtudel on oluline roll ka mulla orgaanilise aine moodustamises. Järelikult on mahetootmises esmatähtis umbrohtude kontrolli all hoidmine, mitte nende absoluutne hävitamine. Umbrohtumine on enamasti probleemiks hõredate külvide puhul, normaalse tihedusega taimik on umbrohtude suhtes konkurentsivõimelisem. Maheviljeluses tuleb kasutada umbrohtumuse kontrolli all hoidmiseks ennetavaid meetmeid, üheks võimaluseks on kasvatada peale põhikultuuri koristamist vahekultuure. Vahekultuurid vähendavad ka toitainete leostumist ja nende poolt... |

| Maintaining or enhancing the stock of soil organic carbon (SOC) is a key factor in sustaining the soil resources of the world. The objective of this research was to study the effect of different farming systems (conventional farming with mineral fertilizers and crop specific fertilization vs. organic farming with organic fertilizers (catch crops and composted manure)) under the same 5-crop rotation (red clover, winter wheat, pea, potato, barley undersown with red clover) system on the SOC stock and the stability of SOC. The second aim was to quantify plant C inputs to the soil and to identify the relationship between C sequestration rate and C input. Data presented in this paper concerned the first rotation during 2008–2012. The main factors were farming... |

| Jätkusuutlikuks maheviljeluseks on oluline arendada viljelussüsteeme, mis tagaksid elurikkuse suurenemise, mullaviljakuse paranemise ja hea ning kvaliteetse saagi. Selles mängib keskset rolli liblikõielisi kultuure sisaldav ja taimetoitainete tasakaalu säilitav kohalikesse oludesse sobiv külvikord. Taimetoitainetega paremaks varustatuseks saab külvikorras kasutada veel vahekultuure, komposte või sõnnikut. Nende lagunemisel muutuvad toitained taimedele kättesaadavaks aeglasemalt ja ühtlasemalt, kindlustades nii külvikorras järgnevate kultuuride stabiilse varustatuse lämmastikuga. Käesoleva uurimuse eesmärk oli selgitada odra ja nisu saagikus ning saagi kvaliteet nende kasvatamisel viieväljases külvikorras kolmes eri maheviljelussüsteemis, mis erinesid... |

| Kartul on üheks armastatumaiks kultuuriks nii meil kui maailmas. Teda on läbi aegade peetud teiseks "leivaks" ning tänapäeval ei kujutaks meist keegi ette toidulauda, kust puuduks kartul (Eremeev jt., 2012). Mahepõllumajanduslikult kasvatatav kartulipind on Eestis pidevalt suurenenud. Samas ei ole seni veel piisavalt andmeid selle kohta, kas põhiliselt vaid mulla toitainevarudel ja haljasväetistaimedel baseeruv majandamine on piisavalt jätkusuutlik. Kas ilma sõnnikuta külvikordades – paljudes mahetaludes ju loomakasvatus puudub – võib toimuda mulla väljakurnamine (Järvan jt., 2014)? Käesoleva töö eesmärgiks oli uurida kuidas erinevate maheviljelusviisidega kartuli kasvatamine mõjutab mulla toitainete sisaldust. |

| The aim of this study was to investigate how different farming systems influenced tuber yields and quality (N, NO3−, P, K, Ca, Mg, dry matter and starch concentrations) of potato as well as how potato cultivation within a crop rotation under different farming systems affects soil quality (pH, Ntot, Corg, plant available P, K, Ca and Mg concentrations). Potato (Solanum tuberosum L.) was part of a five crop rotation experiment in which red clover (Trifolium pratense L.), winter wheat (Triticum aestivum L.), peas (Pisum sativum L.), potato and barley (Hordeum vulgare L.) followed each other simultaneously on a same field. Data presented in this paper concerned the first 3 years of the rotation during 2009–2011. The experiment was performed with six different... |

| Nisu on maisi ja riisi kõrval üks olulisemaid teravilju maailmas. Tema kogutoodangust kasutatakse 75 – 78% inimestele toiduks, ülejäänud läheb valdavalt loomadele söödaks. Euroopas on mahesüsteemis kasvatatud nisu saagikus keskmisena 30 – 40% madalam kui tavasüsteemis kasvatatud nisul, seda enam tuleb hinnata erinevates süsteemides kasvatatud nisu kvaliteeti. Püüli- e peenjahu saak on oluline kvaliteedinäitaja, mida mõjutab suurel määral taimede kasvukeskkond. Peale sorditunnuste sõltub kasvukeskkonnast näiteks tera kõvadus, mis omakorda mõjutab nisuterade jahvatusefektiivsust. Pehmema nisutera jahvatamisel saadakse üldjuhul rohkem ebaregulaarse kuju ja väikese diameetriga osakesi, mis vähendavad jahu voolavust, põhjustades seadmete ummistusi (Evers ja... |

| A five years research run at the experimental station of the Estonian University of Life Sciences in Eerika, Tartu, Estonia since 2008 on Albic Stagnic Luvisol soil, compared the evolution of different elements (Corg, N, P, K) in soil with time, on the basis of conventional and organic farming. For this aim, 80 plots under the same crop rotation (pea, potato, barley, red clover and winter wheat) were divided as follows: 40 cultivated under conventional farming system with different concentrations of mineral fertilizers (20 without addition of chemical fertilizers: N0P0K0; and 20 with a final concentration equals to N125P25K95) and the remaining 40 plots cultivated under organic farming conditions with winter oil-rape after pea, winter rye after potato and... |

| In a field experiment based on a five-year crop rotation (pea, potato, barley undersown with red clover, red clover and winter wheat), several soil parameters, porosity, number and biomass of earthworms, total nitrogen, organic carbon, percentage of water stable aggregates and enzymatic activity, were studied during 2013 and 2014, the first and second year, respectively, since the first rotation concluded. This rotation was managed under three organic farming systems: Organic 0 (control), Organic I (with winter cover crops lately incorporated into the soil as green manure) and Organic II (with the same cover crops plus a yearly amendment of 40 t ha−1 of cattle manure). Crop rotation had a yearly positive effect on the soil bulk density, and enhanced the... |

| Kartuli (Solanum tuberosum L.) hõbekärn (Helminthosporium solani Durieu, Mont) on seenhaigus, mis viimastel aastatel on osutunud tootmises äärmiselt problemaatiliseks. Haigustekitaja nakatab valmivaid mugulaid juba mullas, kuid eoste kaudu levib haigus hoidlas jõudsalt edasi, mistõttu peetakse hõbekärna ka säilitushaiguseks. Patogeen tungib mugulasse läbi loomulike avade siis, kui mugulad on saavutanud juba oma suuruse ja massi, kuid toimub veel koore kinnistumine. Seetõttu on vajalik mugulad põllult võimalikult ruttu koristada. Hõbekärna nakatunud mugulate koore pinnale tekivad pruunikashallid laigud. Kui mugulad puutuvad kokku veega ilmneb nakatunud kohal iseloomulik hõbe-metalne läige. Eriti hästi ongi haigust näha just pestud mugulate pinnalt.... |

| Nitrogen (N) deficiency is a major problem in organic and low-input farming systems. Growing spring cereals with undersown legumes has a positive effect on soil fertility, enriching it with nitrogen, through symbiosis of legumes with nodule bacteria. Two hypotheses were tested: 1) undersowing of red clover increases the protein content of barley grains and 2) mineral N has negative aftereffect on growth of legume plants. The aim of this study was to investigate the effect of organic (cattle manure, off-season cover crop) and mineral N in organic and conventional farming systems on (i) barley (Hordeum vulgare L.) grain yield and quality, (ii) biomass yield formation of undersown red clover (Trifolium pratense L.) and (iii) the aftereffect of mineral... |

| Uurimistulemustest selgus, et punase ristiku allakülviga odra kasvatamine avaldas soodsat mõju mulla mikroorganismidele, suurendades mullaorganismide hüdrolüütilist aktiivsust. Mulla mikroobide hüdrolüütilise aktiivsuse (FDA) määramistulemused olid pärast punase ristiku allakülviga odra kasvatamist tavaviljeluse aladel 18,6% ja mahealadel 37,2% võrra suuremad võrreldes eelvilja (kartuli) alt vabanenud ala mullaga. Katseaastate keskmisena tõusis orgaanilise süsiniku (Corg %) sisaldus maheviljelusviisides 11,6% võrreldes tavaviljelusega. Pärast allakülviga odra kasvatamist võrreldes selle eelsega Corg sisalduses olulisi usaldusväärseid muutusi ei täheldatud. Enne allakülviga odra kasvatamist seos FDA ja Corg vahel sisuliselt puudus. Küll aga esines tugev... |

| In organic agriculture, soil fertility is essential for harvesting high quality crop yields. Plant nutrient cycles should be kept short and as closed as possible. Therefore, it is important to have sustainable growing systems that have rotations with appropriate crops and cover crops. In organic farming green manures and cattle manure are also used to ensure fertile and biologically active soil and to enhance biodiversity. Green manures offer supporting services, such as nutrient cycling, promotion of beneficial insects for pest control and soil formation. Also the catch crops on winter period are essential to reduce nutrient leaching (Stark and Porter, 2005). Growing system does not only influence the soil fertility, but through that also the quality... |

| Keskkonnasõbralik umbrohutõrje maheviljeluses koosneb viljavaheldusest, äestamisest, vaheltharimisest, multšimisest, liblikõieliste kasvatamisest külvikorras ja vahekultuuride (sh talviste kattekultuuride) kasvatamist (Thorup-Kristensen jt., 2003). Käesoleva uurimisega seotud varasemad tulemused näitasid, et talvistest vahekultuuridest rukis osutus umbrohtudele kõige kahjulikumaks, pärssides umbrohuseemnete idanevust. Mõnevõrra vähem toimis raihein, mida oli märgata järgnevates kultuurides - herne ja odra umbrohutaimede tiheduses (Barberi jt., 2014). Lisaks kasvutihedusele vähendasid talvised vahekultuurid ka umbrohtude biomassi (Madsen jt., 2015). Väiksem umbrohtude arvukus ja biomass mõjutavad ka mulla umbrohuseemnete varu. Käesoleva uurimistöö... |
