this study was conducted to investigate the effects of irrigation frequency and substrates on some parameters of greenhouse tomato (cv. hamra) during 1381-1382 at research greenhouse of agriculture college, in ferdowsi university of mashhad. the experiment was based on split plots in the form of completely randomized design and in four replications. irrigation frequency in three levels of 12, 8...

ISHS II International Symposium on Growing Media, Soilless Cultivation, and Compost Utilization in Horticulture Recirculation, circular fertilizers resilience: the potential of growing media systems for production

In the last few decades, soilless culture systems (SCSs) have been gaining worldwide popularity, making them one of fastest-growing sectors in agriculture [...]

abstract colchicum kotschyi boiss (colchicaceae) is one of the sixteen iranian native colchicum species, containing considerable amount of colchicine. to study the effect of different nutrient levels on corm yield and colchicine content of colchicum kotschyi boiss under open field soilless culture, an experiment was performed in a randomized complete design at the horticultural research station...

When lettuce seeds are imbibed and subjected to high temperature for periods of 72 h or more, dormancy known as thermodormaney is induced. Priming of three cultivars of lettuce ( Lactuca sativa L.) seeds in 1% (w/v) K3P O4 for 20 h in the dark reduced thermodormaney. Addition of 100 mg 6-benzyladenine (BA)/liter to the priming solution increased germination in petri dishes at 35C in ‘Green Lake...

In the current scenario of human-driven climate change, extreme weather events will likely affect agricultural production worldwide. Soilless systems have recently arisen as a solution to optimize use natural resources, such water and soil, hence contribute reducing environmental impact agriculture. However, nutritional imbalance due adverse factors, drought, high temperatures, salinity, might ...
