An experiment was conducted to select the optimum nutrient solution for growing lettuce (Lactuca sativa L.) under hydroponic conditions (open system) and Shahrekord climate, as a completely randomized design with five different nutrient solutions and three replicates, in Shahrekord University. The nutrient solutions were: 1) Research Station for Floriculture and Greenhouse Vegetables (the Nethe...
hydroponics technique accompanied by adjustment of nutrient solution seems to optimize crop production and help in establishing sustainable agriculture. in recent years, the greenhouse production of cucumber has been increased in iran, however there are just a few proper nutrient solutions employed in growing the crop. in line with this, an experiment was conducted to find the effect of various...
Effects of nutrient solutions on quantitative and qualitative indices of tulip (Tulipa gesneriana cv. Apricot parrot) were studied in a completely randomized design with 5 nutrient solutions, 4 experimental units and 3 replications. Plants were fed with five nutrient solutions (S1, S2, S3, S4 and S5) having NH4+-N/total N ratios of 0, 0.038, 0.074, 0.11 and 0.14, respectively. All nutrient solu...
this study was conducted to evaluate the responses of two greenhouse tomato cultivars to nutrient solutions' electrical conductivity (ec). two cluster type greenhouse tomato cultivars (razan and ergon) were grown in perlite in a glasshouse hydroponic system. the grown plants were daily fed with either constant ec nutrient solutions (ecs 2, 3 ds m-1) or nutrient solutions of alternatively c...
Lettuce is one of the major leafy vegetables that is consumed as fresh and salads crops. Although, today, the tendency is to grow lettuce as hydroponic crop, there is not an optimal nutrient solution and growers use different nutrient solutions for growing lettuce. Therefore, an experiment was conducted to find an optimal nutrient solution to grow lettuce. In this experiment, the effect of va...
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...
in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...
In order to determine the best nutrient solution and potato cultivar for minituber production in aeroponics and comparison with classic hydroponics, a factorial experiment with three factors of culture system (aeroponics and hydroponics), nutrient solution (Chang et al., APCoAB and commercial nutrient solution of Isfahan), and different potato cultivars (Marfona, Santana and Moren) was carried ...
