Nutrient Solutions for Hydroponic Systems
Among factors affecting hydroponic production systems, the nutrient solution is considered to be one of the most important determining factors of crop yield and quality. This chapter aims to explain aspects related to plant nutrition and its effects on production of hydroponic crops, considering basic aspects such as nutrient solutions and their development through the years; components of nutr...
متن کاملNutrient Management in Recirculating Hydroponic Culture
INTRODUCTION There is an increasing need to recirculate and reuse nutrient solutions in order to reduce environmental and economic costs. However, one of the weakest points in hydroponics is the lack of information on managing the nutrient solution. Many growers and research scientists dump out nutrient solutions and refill at weekly intervals. Other authors have recommended measuring the conce...
متن کاملHydroponic Production of Purslane as a Sodium-removing Vegetable in NaCl-rich Nutrient Solution
To evaluate the potential of producing purslane (Portulaca oleracea L.) as a sodium (Na)-removing vegetable hydroponically at moderate NaCl salinity, two cultivars (Green and Golden) were grown in solutions with added 0, 6, 8, and 10 mM NaCl (the actual Na concentrations ’2, 8, 10, and 12 mM, respectively). At harvest, 26 days after transplanting, apparent growth and biomass accumulation were n...
متن کاملEffects of nutrient solution EC, plant microclimate and cultivars on fruit quality and yield of hydroponic tomatoes (Lycopersicon esculentum)
Four cultivars (Blitz, Mariachi, Quest and Rapsodie) of tomato were grown hydroponically on rockwool in two microclimates (east and west) inside the greenhouse (Tucson, AZ) under two nutrient solution electrical conductivity (EC) levels (2.6 or 4.5 dS m -1 ), adjusted by adding NaCl and CaCl2 after the setting of first fruit truss. In all cultivars, total soluble solid (TSS, %Brix at 20 o C) an...
