to study the effect of seed density and plant distance on yield and growth parameters of radish, an experiment was conducted in research of station rice at office rasht in 2008-2009. this study was set in secondary culture after rice by factorial experiment with randomized complete block design with 3 replications. treatments consisted of factorial arrangement of three seed density levels (5, 1...
Tylosema esculentum (marama) beans and tubers are used as food, and traditional medicine against diarrhoea in Southern Africa. Rotaviruses (RVs) are a major cause of diarrhoea among infants, young children, immunocompromised people, and domesticated animals. Our work is first to determine anti-RV activity of marama bean and tuber ethanol and water extracts; in this case on intestinal enterocyte...
Potato tuber necrotic ringspot disease (PTNRD) is a tuber deformity associated with infection by the tuber necrotic strain of Potato virus Y (PVYNTN). PTNRD negatively impacts tuber quality and marketability, and poses a serious threat to seed and commercial potato production worldwide. PVYNTN symptoms differ in the cultivars Waneta and Pike: Waneta expresses severe PTNRD and foliar mosaic with...
In order to determine the potato cultivars responses to irrigation regimes and fertilizer combinations, an experiment was conducted on Fereidan Research Farm, Isfahan Province in 2003. The trial was designed as split-split plot based on randomized complete block design with three replications. The cultivars (Arinda and Navita) were planted as main plots, and irrigated after 70, 140, 210 mm wate...

In present studies several attempts have been made to reduce the amount of trypsin and chymotrypsin inhibitors in winged bean (Psophocarpus tetragonolobus) mutants developed through induced mutation. The low seed TI (trypsin inhibitor) lines comprised long pod-5 and long pod-2 mutant lines. The low tuber TI feature could be noted in the mutant population. Such lines were long pod-5, large leaf/...
Potato microplants were inoculated with three commercial arbuscular mycorrhizal inoculants, Vaminoc (MicroBio, Hemel Hempstead, HP2 7SU, UK), Endorize IV and Glomus intraradices (both produced by Societe Biorize, 21000 Dijon, France) at establishment in the glasshouse. Monitoring of percentage root length colonization confirmed the persistence of all the mycorrhizal fungi during the trial. Colo...
Energetic carrying capacity of habitats for wildlife is a fundamental concept used to better understand population ecology and prioritize conservation efforts. However, carrying capacity can be difficult to estimate accurately and simplified models often depend on many assumptions and few estimated parameters. We demonstrate the complex nature of parameterizing energetic carrying capacity model...
A study was conducted to investigate the influence of planting methods and tuber weight on growth and yield of local yam cultivars obtained by the minisett technique from white yam (D. rotundata) in Gabon. Trials were carried out in 2014 and 2015 at the experimental ground of the Higher National Institute of Agronomy and Biotechnology, under natural conditions of lightness, temperature and rela...
Abstract To contribute to the development of a novel cropping system for potato grown from greenhouse-derived seedlings hybrid true seeds, planting density trials were carried out under normal Dutch agronomic conditions. For two consecutive years, 5-week-old experimental genotypes transplanted into farmers’ production fields at contrasting locations: flat-bed on sandy soil and traditional ridge...
