The responses of some growth traits of cherry tomato to organic fertilizers in soilless culture

One of the alternative and sustainable methods in agricultural productions field without adverse environmental effects is using non-chemical alternative in agriculture. Plant grows stimulants and organic fertilizers are one of these alternatives. present research is done in order to investigate the possibility of using Ascophyllum nodosum brown algae and vermicompost extracts on cherry tomato with the purpose of reducing the use of chemical fertilizers. For this purpose to investigate the effect of different concentrations and determine the appropriate amount of consumotion in hydroponic culture a pot experiment is done as factorial in a completely randomized design with three replications in a green house in Mashhad(4102 -4102).and 0, 2,4 and 6 concentrations per thousands of each two treatments was tested. The results analysis of data variance showed that reaction of plants is different to consumption levels.By increasing the concentration all variables was increased compared to control. According to performed pot test results brown algae extract and then after it vermicompost extract with the highest level consumption rather than other concentrations specially control treatment had the most positive effects on plant growth elements.in total it can be said that both treatments can play a positive role to reduce the use of chemical fertilizers consumption and environment pollution reducing, plant health, growth attributes and nourishment and use as a materials with natural resource for growth and development of cherry tomato in ecologic agriculture and hydroponic cultivation
