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...

A composite model was developed for water and mineral relations of greenhouse tomato (Solanum lycopersicum L.) cultivated in semi-closed or open soilless (rockwool) culture. The model simulated on a daily basis: (i) the evolution of crop leaf area index and water uptake using empirical equations; and (ii) the variations of ion concentrations and electrical conductivity (EC) in the recirculating...

With the aim of defining the best management of nutrient solution (NS) in a soilless system for obtaining high quality baby-leaf rocket, the present study focuses on two wild rocket genotypes ("Nature" and "Naturelle"), grown in a greenhouse under two Southern Italy growing conditions-autumn-winter (AW) and winter-spring (WS)-using two soilless cultivation systems (SCS)-at two electrical conduc...

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 ...

Cyanobacteria are found to be renewable and sustainable additives for growth improvement in crops. Extracts biomass of three nitrogen-fixing cyanobacteria namely, Roholtiella sp. (QUCCCM97), Nostoc ellipsosporum (QUCCCM99), Desmonostoc danxiaense (QUCCCM112) isolated from Qatar desert environment were tested their ability enhance the bell pepper (Capsicum annuum L.) seedlings. Soilless cultivat...
