This research work aimed to study the effect of different mixtures of growing media
on pepper seedlings and their ability to withstand transplanting shock.The variety QarnAlgazal
of pepper and five mixtures of growing media were used.The mixtures i
ncluded bitmoss
alone,bitmoss with equal volume of soil or sand,soil and cow manure in a ratio of
1:2,and cow manure with soil and sand in a ratio of 1:1:1.
The experiments were implemented in aplastic green house without heating in the
nursery farm of the faculty of Agriculture,Tishreen University.The completely randomizel
design was adopted with three replications for each treatment and 15 plants for each replication.
The results showed that themedia containing cow manurewere the more effective ingrowth
of sapling as represteded by the increased hieght of sapling, number and area of
leafs,fresh weight of both biomass and roots of sapling.The effect was very clear in the
media containing cow manure and soil in the ratio of 1:2.
The experiment was carried out to assess the germinability and seedling
growth rate of some treated vegetable seeds (i.e. onion, carrot, and tomato) with
aerated - aqueous solutions.
Seeds were treated for 24 hours with 0.1% of both succinic acid
and
nutrient solution, and the seeds to medium ratio was 1:5.
The soaking solution was continuously aerated by an air pump. At the end
of treatment, the seeds were dried up at room temperature to eliminate the
excess superficial moisture.
The aim of this study was to test the effeciency of some organic and bio fertilizers in
improving the seeds germination and transplants growth of pepper Capsicum annum L.
local variaty" Qorn Algazal":by using two commercial compounds; organic (Hube
st) and
one bio (EMI) fertilizers. Two experiments were used; the aim of the first was to study the
effect of these fertilizers on germination of seeds in Petri dishes and plastic peatmoss peds.
Whereas the aim of the second experiment was to evaluate the effect of the fertilizers on
the pepper transplants growth that prepared in the 5 * 5 Striopor peatmoss plates placed in
un warmed plastic tunnel.
The results showed that the soaking of pepper seeds in the tested fertilizers, provoked
and the germination increased the seeds, vigor, with a significant performance of the bio
fertilizer.
The results also showed that the treated transplants with the tested fertilizers gave an
increase of the transplants growth ratio (the height, leaves number and foliar surface area,
the dry and wet weight) with a significance superiority of the bio fertilizer.
The research aims to study the effect of the treatment of the
eggplant seeds- pink local kind in some seaweed extracts to improve
the germination characteristics, as well as the study of their impact
on the growth of the resulting seedlings and their ability to
withstand the transplanting shock.
