This experiment was carried out to investigate effects of onion extract on growth performance, meat quality and blood profiles of White mini broilers. Total of 600 one-d-old male White mini broiler chicks were divided into four groups and fed control diets (non-medicated commercial diet or antibiotics medicated) or experimental diets (non-medicated diets containing 0.3% or 0.5% onion extract) f...

Research was carried out on antibacterial activity of Allium cepa. Two different extracts were made from Allium cepa (onion) using distilled water. The extracts include fresh onion extract and cold water extract. The antibacterial activity of the onion was tested on four bacteria isolates associated with various ocular infections. The bacterial isolates include: Escherichia coli, Staphylococcus...

The objective of Onion Routing is to make it completely impossible for third parties to perform traffic analysis. This goal is achieved by applying cryptographic techniques to networking. The packets transiting the chain of onion routers thus appear anonymous. Yes, we are talking about a chain. Practically speaking, there is a group of onion routers distributed around the public network, each o...

Onion (Allium cepa L.) is a vegetable that is widely consumed due to its flaouring and healthpromoting properties. A randomized complete block factorial experiment was carried out in Payame Noor University, Marivan center, in order to study the effects of rates of nitrogen, phosphorus and sheep manure on the yield and quality of onion. The first factor consisted of two sheep manure levels (0 an...

An experiment was conducted to study the effect of sulphur application on growth, yield and quality of onion at Horticulture Farm of Institute of Agriculture, Visva-Bharati, Sriniketan. The treatments consisted of six incremental doses of sulphur application (10, 20, 30, 40, 50 and 60 kg ha-1) and no sulphur application (control, 0 kg S ha-1). Treatments were arranged in Randomized Block Design...

Populations of onion thrips, Thrips tabaci Lindeman, from commercial onion fields in New York were evaluated for their susceptibility to the commonly used pyrethroid, lambda-cyhalothrin (Warrior T), using a novel system called the Thrips Insecticide Bioassay System (TIBS). To use TIBS, thrips are collected directly from the plant into an insecticide-treated 0.5-ml microcentrifuge tube that has ...

A glutathione S-transferase (GST, EC 2.5.1.18) inhibitor was isolated from the onion bulb by fractionation and purification using Sep-pak Vac C18 column, TLC and HPLC. Five partially purified onion bulb GSTs (GSTa and GSTb as minor GSTs, and GSTc, GSTd and GSTe as dominant GSTs) separated by DEAE column were used to detect the inhibitory substance in onion bulb extract. Among the three fraction...

The consumption of fruits and vegetables that have high polyphenol content has been previously associated with a reduced risk for cardiovascular disease. We investigated the effects of onion peel extract on plasma total antioxidant capacity, lipid peroxidation, and leukocyte DNA damage. This study was a randomized, double-blind, placebo-controlled, crossover trial. Healthy female subjects recei...

Volunteer potatoes are difficult to control in onions and can greatly reduce onion growth and yield. Herbicides and cultivation were evaluated for control of simulated volunteer potatoes in onions in 1996 and 2000. Three interrow cultivations did not control potatoes in the onion row and the remaining plants reduced onion yield 50 and 73% compared with the hand-weeded checks. Three applications...

Some intervention studies have shown that quercetin supplementation can regulate certain biomarkers, but it is not clear how the doses given relate to dietary quercetin (e.g. from onion). We conducted a two-period, two-sequence crossover study to compare the bioavailability of quercetin when administered in the form of a fresh red onion meal (naturally glycosylated quercetin) or dietary supplem...
