The growth and development of Cuscuta chinensis Lam., and the effects of the holoparasite on the growth and yield of tomato (Lycopersicon esculentum), chilli (Capsicum annuum) and rice (Oryza sativa) were investigated in pot experiments under glasshouse conditions. ‘Mature’ and ‘immature’ seeds of C. chinensis showed 15 and 47% germination, respectively. The independent life duration of seedlings from ‘immature’ seeds was 6 days shorter than ‘mature’ seeds (19 days). Cuscuta chinensis formed haustoria on chilli and tomato, but not on rice seedlings. Infection with three C. chinensis seedlings per host plant reduced leaf area, dry weight, carbon and nitrogen content by 78–84% and 27–44% in tomato and chilli plants, respectively. Dry weight of C. chinensis was 0.63 g per pot in tomato, and 0.24 g per pot in chilli. Carbon and nitrogen content of C. chinensis was 0.189 and 0.028 g per pot, respectively, when grown with tomato. When it was grown with chilli, the carbon and nitrogen content of C. chinensis was 0.001 and 0.007 g per pot, respectively. Cuscuta chinensis reduced the fruit yield of tomato and chilli by 72 and 29%, respectively. The results indicated that tomato is a preferred host of C. chinensis compared with chilli, and rice is not preferred. In the host–parasite associations, C. chinensis suppressed growth and yield of chilli and tomato by diverting the elaborated products of metabolism of the hosts.

“…The application of sand to frozen cranberry beds during the winter or early spring has been a part of this fruit crop's production practices since the early 1800s. Growers apply the sand to bury emerging weed seedlings (Sandler et al 1997) and to encourage lateral shoot production of the cranberry vines (Eck 1990). Below the alternating layers of OM and sand is about 30 cm of pure sand.…”

Even though nitrogen (N) is a key nutrient for successful cranberry production, N cycling in cranberry agroecosystems is not completely understood. Prior research has focused mainly on timing and uptake of ammonium fertilizer, but the objective of our study was to evaluate the potential for additional N contributions from hydrologic inputs (flooding, irrigation, groundwater, and precipitation) and organic matter (OM). Plant biomass, soil, surface and groundwater samples were collected from five cranberry beds (cranberry production fields) on four different farms, representing both upland and lowland systems. Estimated average annual plant uptake (63.3 ± 22.5 kg N ha -1 year -1 ) exceeded total average annual fertilizer inputs (39.5 ± 11.6 kg N ha -1 year -1 ). Irrigation, precipitation, and floodwater N summed to an average 23 ± 0.7 kg N ha -1 year -1 , which was about 60% of fertilizer N. Leaf and stem litterfall added 5.2 ± 1.2 and 24.1 ± 3.0 kg N ha -1 year -1 respectively. The estimated net N mineralization rate from the buried bag technique was 5 ± 0.2 kg N ha -1 year -1 , which was nearly 15% of fertilizer N. Dissolved organic nitrogen represented a significant portion of the total N pool in both surface water and soil samples. Mixed-ion exchange resin core incubations indicated that 80% of total inorganic N from fertilizer, irrigation, precipitation, and mineralization was nitrate, and approximately 70% of recovered inorganic N from groundwater was nitrate. There was a weak but significant negative relationship between extractable soil ammonium concentrations and ericoid mycorrhizal colonization (ERM) rates (r = -0.22, P \ 0.045). Growers may benefit from balancing the N inputs from hydrologic sources and OM relative to fertilizer N in order to maximize the benefits of ERM fungi in actively mediating N cycling in cranberry agroecosystems.

“…In addition, sanding may stimulate root growth and encourage decomposition of organic matter (DeMoranville et al, 1996;Strik and Poole, 1995). Sanding also provides some pest management benefits, including burial of cranberry girdler (Chrysoteuchia topiaria Zeller) pupae (Franklin, 1951;Tomlinson, 1937) (Sandler et al, 1997).…”

Field conditions associated with commercial cranberry (Vaccinium macrocarpon Ait.) production were simulated in greenhouse studies to determine the effect of soil surface characteristics on dichlobenil activity. Sand was compared with organic matter, in the form of leaf litter, as the surface layer. A seedling bioassay using alfalfa (Medicago sativa L.), a dichlobenil-sensitive plant, was employed to determine root growth response on herbicide-treated soil. When the herbicide was applied to a sand surface, root growth was greater as time after application elapsed, indicating loss of herbicide activity. Conversely, the presence of organic matter on the surface prolonged the activity of the herbicide. Composition of the surface layer was more important than the depth of the layer in determining herbicide persistence. The influence of cultural practices, such as the application of sand or the removal of surface debris, on herbicide activity should be considered when planning weed management strategies for cranberry production. Chemical name used: 2,6-dichlorobenzonitrile (dichlobenil).
