| Kartuli kuivlaiksust (Alternaria solani, A. alternata) on seni Eestis peetud suurt kahju põhjustavaks kartulihaiguseks. Viimastel aastatel on kuivlaiksus osutunud suureks probleemiks Eesti kartulipõldudel, seda eriti just vastuvõtlikel sortidel. Kuumadel keskmise niiskusega kasvuaastatel on kuivlaiksusele vastuvõtlikel sortidel vaja tavaviljeluses teostada keemilist tõrjet, kuna haigus hävitab enneaegselt kartuli lehestiku, sageli enne veel kui lehemädanik lööbida jõuab. Kuivõrd maheviljelus välistab keemilise tõrje, siis tuleb leida kasvatustehnoloogilisi võtteid ning kasutada võimalikult haigusekindlaid sorte. Uurimustöö eesmärgiks oli selgitada, kuidas erinevad maheviljeluse tehnoloogiad mõjutavad kartuli kuivlaiksuse arengut haigusele soodsal... |

| Nowadays, organically produced products have become more popular than ever and interest in them is still growing fast. The early blight causal pathogen Alternaria solani has not been considered a great threat to potato in northern climate conditions in the past and has not been routinely sprayed against. During our study early blight was evaluated in 2010 and 2011 on the plants of a potato cultivar ‘Reet’ in an organic farming experiment. In our study, both growing seasons were very favourable for early blight development. Significant differences between the two cultivation technologies were found (F1,12 = 4.84, p = 0.048). In 2010, the area under disease progress curve (AUDPC) value was 303 on cover crop (CC) plots and 990 on CC + M (manure)... |

| Viie katseaasta (2012–2016) keskmised tulemused näitavad, et võrreldes tavasüsteemidega on maheviljelussüsteemidel eelised kestlikuks taimekasvatuseks. Viljelussüsteemi mitmekesistamine vahekultuuride ja lisaks veel kompostitud veisesõnnikuga, võimaldab oluliselt parandada mulla omadusi. Tõusis mulla mikroobide aktiivsus, mulla orgaanilise süsiniku ja üldlämmastiku sisaldus. Mulla mikroobide aktiivsuse ja üldlämmastiku sisalduse vahelised seosed aga vajavad jätkuvaid uuringuid. |

| A study was conducted which aimed to investigate the effect of farming systems (FS) (four conventional with increasing mineral N fertilizer amounts 0–150 kg of N ha−1) vs. two organic with catch crops (CC) and cattle manure (CC+M)) under the same five crop rotation system on the occurrence of tuber diseases such as common scab (Streptomyces spp.), silver scurf Helminthosporium solani), dry rot (Fusarium spp.), and soft rot (Pectobacterium spp.). As the average of the first rotation years 2009–2011, the FS had a significant effect on the occurrence of silver scurf, dry rot and common scab (surface cover <30 %). The organic systems had significantly more tubers (around 39 %) infected with common scab (surface cover 4–15 %) than in conventional systems... |
