Zinnia is an annual plant with the long flowering period from late spring to mid-autumn. It is a popular plant for landscape. In the present study, the effect of two types of growth promoting bacteria and Azolla compost on some ornamental characteristics of Zinnia were evaluated in pot cultivation and greenhouse conditions. The factorial experiment was conducted in three replications based on a...

This experiment was performed to investigate the effect of Azolla and rice straw mixed compost in peat substitution on Dieffenbachia amoena. Factorial experiment based on a completely randomized design with two factors of nutrient solution in 2 levels (1- without solution, 2- with 130 mg N/ l, 32 mg P /l and 117 mg K/ l) and 5 levels of Azolla and rice straw mixed compost (zero, 15, 30, 45 and ...

In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...

Effect of Different Substrates Containing Azolla Compost and Rice Bran on Vegetative Physiological Traits Three Pothos Cultivars

climatic conditions of guilan have caused to develope azolla growth in wetland and ponds. regarding environmental problems of azolla accumulation, a study was conducted to investigate impact of composted azolla with nutrient solution on the growth of dracaena in replacement of peat in ornamental plants and flower research station, lahijan, iran. the control treatment was a 2:1 ration of peat: p...

Attempts to increase food crop yields by intensifying agricultural systems using high inputs of nonrenewable resources and chemicals frequently lead to de-gradation of natural resources, whereas most technological innovations are not accessible for smallholders that represent the majority of farmers world wide. Alternatively, cocultures consisting of assemblages of plant and animal species can ...

It can by using organic and bio-fertilizer minimize vegetables plants requirements from inorganic synthetic fertilizers which are potentially more detrimental to the environment. The objective of this work was to study the response of sweet pepper plants cv. California Wonder to some micro-organisms and organic fertilizer by soil inoculation with different rats of compost tea (10 or 20 L/fed.) ...

Abstract The improvement of water quality through aquatic plants’ nutrient uptake is one the crucial elements in achieving a sustainable ecosystem. Water affected by variety variables, including dissolved oxygen concentrations, overabundance, bacterial populations, salt content, and number suspended particles water. This experiment was performed to evaluate biological biochemical characteristic...

one of the most important steps of agaricus bisporus production is casing. in this step a layer of soil is added on top of compost. peat is the most suitable casing soil for a. bisporus production. the lack of peat in iran is one of the major problems in a. bisporus production for mushroom producers. it seems that peat can be replaced by spent mushroom compost (smc). in order to study the possi...
