azospirillum is a well-studied genus of plant growth-promoting bacteria. phytohormone production by pgpr is considered as one of the effective factor to increase the tomato yield significantly. in order to study the effect of azospirillum inoculant on on growth characteristics and yields of tomato, three strain of azospirillum were isolated, identified, and purified from tehran suburb soils. to...
Background and purpose: Traditionally, probiotics are extensively incorporated into fermented dairy products. Dairy products could cause two major problems including allergy to milk protein and lactose intolerance, which ultimately lead to limited consumption of these foods. Today, fruit or vegetable drinks are ideal sources of probiotics for consumers. In this study, we investigated the possib...
Among the most important quality parameters of irrigation water used for greenhouse crops, alkalinity of water is considered critical due to its impact on pH of soil or growing medium solution. In this study, shoot and root Fe contents and SPAD index were investigated in non-grafted and grafted tomato (greenhouse tomato) plants onto five rootstocks (eggplant, datura, orange nightshade, local Ir...
Phyllocnistis citrella Stainton, the citrus-leafminer, is an important pest of citrus worldwide. Knowledge of natural parasitism levels is fundamental to the establishment of tactics of management and control of this species. This work aimed to evaluate the parasitism in two citrus orchards, one of ‘Montenegrina’ (Citrus deliciosa Ten.) and the other of ‘Murcott’ (C. sinensis (L.) Osbeck x C. r...
The parasitoid assemblage associated with a lepidopteran leafminer, Coptotriche japoniella (Tischeriidae), on an evergreen tree, Eurya japonica (Theaceae), was studied in the center of Japan to explore parasitoid coexistence mechanisms. The leafminer supported 12 parasitoid species. Eight abundant or common species were classiÞed into Þve guilds according to their koinobiont/ idiobiont mode and...
The leafminer Liriomyza huidobrensis Blanchard is considered a key pest for potatoes in Argentina. Population dynamics and leaf damage caused by the leafminer on seven selected potato processing varieties were assessed at Balcarce during the 2002 and 2003 growing seasons. Adult population dynamic was monitored using yellow sticky traps, while leaf damage (punctures and mines) was assessed using...
In order to determine and evaluate the mechanization indices, including energy and economic, in production of greenhouse cucumber and tomato, a study was carried out using sequential design- factorial with three replications in Khuzestan province, Iran, during 2011-2012. The greenhouse structures and production methods in all the systems were similar. The evaluated treatments included two culti...
powdery mildew is one of the most important disease concerns of tomato production in different regions of the world, which is caused by different species of erysiphales. the most important causal agents of which are leveillula taurica and oidium neolycopersici. in the present study tomato farms in qazvin province were surveyed and tomato leaves with powdery mildew symptoms were collected. after...
