now a day winter cover crops planting has been attended to reduce herbicide application. an experiment was carried out at the research farm of agriculture faculty, bu- ali sina, university, in 2009. the experiment was a randomized complete block design with three replications. the trial included of five treatments consists of no cover crop, rye, winter oilseed rape, barley and triticale. the re...
potato is one of the most productive crops in agriculture and is a valuable food source in developing countries. mycorrhizal fungi involve a symbiosis with most of crop roots and leads to improve the crops growth and yield. in order to investigate the effect of mycorrhiza fungi species on yield of potato cultivars a factorial experiment was arranged in a randomized complete block design with ei...
Global organic agriculture and consumption of food has continuously increased over the past decades. The aim research was to determine compare cadmium (Cd) lead (Pb) concentrations in conventional root tuber vegetables from Serbian market. Samples three commonly consumed Serbia, including potatoes, carrots beetroots, were collected at two green markets four supermarkets territory city Belgrade,...
Arbuscular mycorrhizal fungi (AMF) are widely distributed in nature. They live in the roots of higher plants, in a symbiotic relationship. In this study, five commercial species of yams (Dioscorea spp.) were inoculated with six species of AMF, Glomus clarum, G. etunicatum, G. fasciculatum, Gigaspora sp., G. mosseae, and Acaulospora sp., in field cultivation conditions to investigate the influen...
Nitrogen (N) uptake (kg ha-1) of field-grown potatoes was measured in 4.32 m2 lysimeters that were filled with coarse sand, loamy sand, and sandy loam and subjected to full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation strategies. PRD and DI as water-saving irrigation treatments received 65% of FI after tuber bulking and lasted for six weeks until final harvest. Results show...

Studies were conducted to determine the role of 3-methylthioproprionic acid (MTPA) in the pathogenicity of potato stem canker, Rhizoctonia solani, and the concentrations required to inhibit growth of R. solani under laboratory and plant house-based conditions. The experiments were laid out in a completely randomized design with five treatments and five replications. The treatments were 0, 1, 2,...
The source-sink relationship determines crop yield, and it is largely regulated by water and nutrients in agricultural production. This has been widely investigated in cereals, but fewer studies have been conducted in root and tuber crops such as potato (Solanum tuberosum L.). The objective of this study was to investigate the source-sink relationship in potato and the regulation of water and n...
ABSTRACT: Yam is a tuber vegetable crop with vegetative propagation. The low yielding due to the difficulty of obtaining quality material for propagation and high cost acquisition. cutting technique new alternative yam. present studyevaluated production minitubers yam through cuttings, follow formational growth minitubers. Different types obtained from three positions on shoots, substrates were...
in this study, the amount of total phenol, chlorogenic acid, catechin, quercetin, phloridzin, cyanidin and antioxidant activity of apple (malus domestica) skin and flesh of six iranian cultivars, including: ‘golab kohanz’, ‘sib torsh dirras’, ‘ghara yapragh’, ‘torkman’, ‘ghezel alma’ and ‘abbasi mashhad’, and four commercial cultivars including: ‘golden delicious’, ‘red delicious’, ‘braeburn’ a...
