ABSTRACT The objective of this study was to evaluate the technical viability using longer recirculation intervals nutrient solution than those conventionally used for acclimatization Prata-Ana banana seedlings grown under hydroponic system. experiment carried out in a greenhouse plantlet production biofactory, Cruz das Almas, Bahia, Brazil, randomized block design with four replications. use (0...
Sterile peat used as biofilter medium, was amended with four different concentrations of a nutrient solution, inoculated with a toluene-utilizing consortium. Samples were incubated over 120 days in closed environments microcosms with water vapor and toluene saturation to emulate the conditions prevailing in biofilters. An improvement on toluene consumption rates, associated with microbial growt...
abstract soil nutrient management with efficient fertilizer use has an important role on maximizing yield and environmental effects. in this study game theory is applied to identify the nutrient proportion for corn production in kooshkak in fars province, iran, in 2008-2009. cost of fertilizer combinations and production of corn are the players of the game. a goal programming was applied to obt...
The effect of salinity and nitrogen on yield, vitamin C, citric acid and nutrient distribution of tomato in hydroponics culture was investigated. Tomato seeds were first let germinate in yonolit pots with wet coco peat and then their seedlings were transferred to plastic tanks containing 5 liters nutrient solution. Treatments were three levels of salinity (0, 30 and 60 mM as NaCl and CaCl2) and...
