Aloe vera is one of the most popular ornamental plants that is widely used in production of medicines and cosmetics. To investigate the effect of different ratios of peat and perlite on quantitative and qualitative characteristics of Aloe vera, a split-plot experiment, arranged as completely randomized design, with five substrates (peat, peat and perlite (1:3 v/v), peat and perlite (1:1 v/v), p...
melon produced by transplanting cause seed saving, reduce the risk of cold, pest and disease stress. in order to investigate the effects of growing medium and cultivars on characteristic of melon's transplants, an experiment was conducted based on randomized completely design with 10 replications at the ferdowsi university of mashhad during 2010. treatments included 6 levels of growing medium (...
This research was performed to study the effect of direct planting and transplanting of potato minituber on its yield and yield components. The experiment was designed as a randomized complete blocks with nine treatments and three replications. Treatments were one direct and eight indirect planting. In order to prepare the nursery, two types of pots (peat and nylon) and four types of substrates...
Salinity is a very serious problem for agricultural development, especially in arid and semi-arid regions. On the other hand, many benefits of soilless culture have caused the expansion of these systems in these areas. In this research, in order to investigate the effects of different substrates and salinity stress on physiological characteristics and yield of broccoli, an experiment was conduc...
poinsettia as an ornamental pot plant is widely grown in peat-based substrates with high phosphorus (p) fertilization. the aim of current study was to evaluate the p demand of poinsettia according to its depletion ability during the growth stages by using a mechanistic simulation model. for this purpose, rooted poinsettia cuttings were grown in the medium with 80: 20 (v: v %) peat+ mineral comp...
To study the effect of different substrates on growth and yield of gerbera, this experiment was carried out as randomized completely block design with 14 treatments and 3 replications. Treatments were as fallowing: fine sand, peat+fine sand (25%+75%), peat+fine sand (50%+50%), perlite+peat (75%+25%), perlite+peat (50%+50%), perlite+peat (25% +75%), perlite+peat+expanded clay (25%+70%+5%), perli...
Dut to econemic and envaironmental limitiations of peat moss as a growth medium for ornamental plants, researchers seek an apporiate alternative in flower and plants industry. Zeolite, due to its high potential in water holding capcity and cation enchange capacity, has the ability to replace peat moss. To investigate the posibility of subtituting peat moss by zeolite as a proper medium for grow...
abstract this study was performed in order to determine a suitable alternative substrate for peat in soilless culture in 2007. different plant wastes including carbonized rice hull, saw dust and dry pine leaves (pinus eldarica) were examined. treatments were 100% peat as control, peat plus dry pine leaves (1:1 v/v), peat plus carbonized rice hull (1:1 v/v) and peat plus saw dust (1:1 v/v). the ...
To evaluate the effect of different culture media on growth indices of Pelargonium ×hortorum “Maverick Star” in plug culture, a greenhouse experiment was carried out based on a completely randomized design with seven treatments and four replications. The treatments were seven different substrates including peat moss (100%), cocopeat (100%), peat moss + cocopeat (60%+40%), peat moss + cocopeat (...
in order to evaluate the possibility use of palm waste cellulose as a substitute substrate for growing pot plants, an experiment was conducted in completely randomized block design with 6 replication and six treatments on aglaonema sp. the treatments were 5 levels including 0, 25, 50, 75 and 100 palm celluloid wastes mixed with different rates of some amendments such as peat, coconut coir, perl...
