“…A good biofumigation crop for nematode management should be a poor host for target nematode species (Edwards and Ploeg 2014) and also have high glucosinolate production (Monfort et al, 2007). In our previous study, we investigated 40 genotypes from 15 different Brassica species initially to assess their host suitability level of rootknot nematodes (M. arenaria and M. incognita) and 12 genotypes were found to be as poor host with low potential of nematode multiplication as cover crop for biofumigation (Aydınlı and Mennan 2016).…”

“…Soil incorporation of broccoli was reported to reduce root galling on tomato by 36% (Lopez-Perez et al, 2010). Monfort et al, (2007) reported that incorporation of selected Brassica species as green manure lowered nematode populations and root damage caused by M. incognita infection more than nonBrassica species. However, nematode control activity was found variable among Brassica species depending on host suitability level (Morra and Kirkegaard 2002;Zasada et al, 2003;Hartz et al, 2005;Monfort et al, 2007;Ntalli and Caboni 2012;Avato et al, 2013).…”

“…Soil-borne pests and diseases suppression by product of glucosinolate hydrolysis (most commonly isothiocyanates) released from incorporated plant tissues related to identities and concentrations of glucosinolates in plant tissue (Morra and Kirkegaard 2002). Therefore, it is crucial to know glucosinolate content of the plants to be used for biofumigation.A good biofumigation crop for nematode management should be a poor host for target nematode species (Edwards and Ploeg 2014) and also have high glucosinolate production (Monfort et al, 2007).

Brassica species are sources of bioactive compounds with several biological properties including biocidal activity against various soil borne pathogens and pests such as parasitic nematodes. Isothiocyanates derived from corresponding glucosinolates are major bioactive compounds responsible for this activity. In this study, glucosinolate content of red and white radish (Raphanus sativus L.), oilseed rape (Brassica napus L.), turnip (Brassica rapa L.) and Arugula (Eruca sativa L.) that were previously assessed for their host suitability level of root-knot nematodes (Meloidogyne arenaria and Meloidogyne incognita) were determined to understand the relationship between glucosinolate content and host-suitability level of these crops. The highest glucosinolate content was in radish. Turnip revealed lower levels compared to radish. However, the lowest glucosinolate content was determined in arugula and oilseed rape. Together with previous findings demonstrating host-suitability levels, the effect of glucosinolates on biocidal potential of Brassicaceae plants to fight against root-knot nematodes were evaluated.Copy Right, IJAR, 2017,.

Introduction:-The incorporation of plants containing specific biologically active compounds into soil against soil-borne pests is a natural plant protection approach. The Brassicaceae plants synthesize glucosinolates (GSL) that are sources of bioactive compounds such as isothiocyanates with several biological properties including biocidal activity. They are classified as aliphatics, aromatics or indoles having different properties and functions. Genetic factors determine the glucosinolate profile of plants, therefore the glucosinolates produced by a plant may vary. Glucosinolate content, however, is under the influence of environmental factors as well as stress factors during the growth period as reviewed by Sarıkamış 2009. Although present in the entire plant, the amount of glucosinolates is variable at different plant parts and plant growth stages (Brown et al., 2003).Glucosinolates are hydrolyzed by endogenous myrosinases to produce an array of compounds including isothiocyanates, nitriles and indoles. Among these compounds isothiocyanates are associated with several biological activities including the suppression of soil borne pests (Lin et al., 2000). Benzyl isothiocyanate derived from the Corresponding Author:-G. Sarıkamıs. Address:-Ankara University, Faculty of Agriculture, Department of Horticulture, Ankara, Turkey. ISSN: 2320-5407Int. J. Adv. Res. 5(10), 271-278 272 hydrolysis of glucotropaeolin and 2-phenylethyl isothiocyanate has been shown to have high levels of antibacterial activity (Jang et al., 2010) and toxicity to several soil pathogens including nematodes and fungi (Jensen et al., 2010). Root-knot nematodes are plant parasitic nematodes that cause high losses in plants by reducing its quality and quantity. Chemical nematicides including soil fumigants have effectively controlled nematodes (Nyczepir and Thoma...

Cover crop mixtures enhance stability but not productivity in a semi‐arid climate

et al. 2021

 Cover crop mixtures did not out-yield the most productive single species plantings  A 6-species cover crop mixture resulted in more stable cover crop yields across sites and years  Grasses contributed greater biomass and more consistently to mixture production  Kale productivity increased in the dry year making it a good choice for drier climates ABSTRACT Cover crops are a critical component of sustainable agroecosystems, yet their performance in semi-arid environments with short growing seasons and highly variable precipitation is inconsistent. To evaluate productivity and stability of single species vs. multi-species cover crop plantings with variable water input, cover crops were evaluated at two sites in North Dakota under dryland and dryland plus irrigation conditions. Cover crop treatments consisted of three warm-season monocultures, a three warm-season species mixture (MIX3), and a three warm-season and three cool-season species mixture (MIX6). Averaged across year and water regime, biomass production was not greater for mixtures (8693 kg ha -1 , MIX3; 10212 kg ha -1 , MIX6) than for the most productive monoculture (11295 kg ha -1 , sunflower) at the West site. The same held true at the East site (7486 kg ha -1 , MIX3; 8603 kg ha -1 , MIX6), with cowpea producing the most biomass, 10886 kg ha -1 , of all monocultures. At the West site, variability in production was lowest for MIX6 when pooled across year and water regime (CV = 25%) compared to monocultures (CV ≥ 49%). At the East site, cowpea had the lowest CV (24%) while mixtures averaged 35%. Pooled across sites, production in the MIX6 plots had the lowest variability (29%). Grasses consistently contributed to high proportions of total biomass production compared to other functional types.

The results indicated that some Brassica crops, particularly mustard and canola, had the potential to significantly reduce Phytophthora blight on squash when used as soil amendments. As P. capsici has a remarkable ability to develop resistance to chemical fungicides, use of effective Brassica cover crops could be a biorational alternative to fungicides and a valuable component in developing integrated disease management programs.
