Seeds of four vegetable crops; carrot (Daucus carota L. cv Nantes 2-Tito), cucumber (Cuucumis sativus L. cv Special), onion (Alium cepa L. cv Red Creole) and tomato (Lycopersicon esculentum Mill. cv Tanshet Star) were stored under a wide range of temperature (5, 15, 25 and 35°C) and relative humidity (RH) The quality of stored seeds was tested by measuring(More)
Shading the greenhouses is necessary in summer to reduce the solar radiation load. This however generates a considerable amount of thermal radiation heat load that needs to be removed via cooling systems. This study aimed to evaluate the effect of different shading configurations on the solar and thermal radiation in a greenhouse. Nets at four different(More)
Under harsh weather conditions, closed transplant production systems (CTPS) are currently used to produce high quality transplants under artificial lighting. More than 70% of the electric energy consumed in the CTPS is for lighting. This article presents a simulation study to examine the possibility of using an alternative closed solar house, with radiation(More)
This study assessed effects of irrigation water regimes and humic acid (HA) application on vegetative growth, yield, tuber quality and water use efficiency (WUE) of potato. Five irrigation treatments were applied at three developmental stages; (WR1) control (100 % crop evapotranspiration, 100 % ETc) at all plant growth, (WR2) 75 % ETc at all stages, (WR3)(More)
