An experiment was conducted in agricultural college arboretum that belong to
tishreen university on okra during the growing season of 2013-2014 to investigate the
effect of spraying by organic fertilizers and growing point pinching on the growth an
d
yield.
The experiment include 8 treatments as control (without spraying by organic
fertilizers or growing point pinching), two kinds of organic fertilizers (ultra humic acid and
amino vega) with or without growing point pinching. Plots were completely randomized
over the experimental area having four replicates for each treatment. Each replicate
contained 14 plants.
Results showed that the highest values of vegetative growth parameters are stem
length branch number ,leave number per plant due to the interaction between pinching of
growing point and spraying by ultra humic acid and amino vega . The experiment results
revealed also ,that the highest yield and The largest number and weight of fruits was
produced from growing point pinching and spraying by ultra humic acid and amino vega,
compared to all other treatments.
This search was carried out in Abi Garash farm, Faculty of Agriculture,
Damascus University to study the efficiency of using “Agerton” as a fertiliser;
either by irrigation or a foliar spry on tomato seedling. Four varieties were
used (Astona, Tyr
ad, E26 and Local).
Results showed that the treatment by the fertilizer resulted in an increase in
growth thorough the plant length increasing. This increase was about 1.1 and
1.2 folds for all varieties and types of treatment (irrigation and foliar spry), as
compared to the control.
Moreover, the using of fertilizer led to a significant increase in the yield of
plant, which increased by 1.2 and 1.5 in Astona; 1.2 and 1.4 in E26, 2.2 and 2.3
in Local and 1.5 and 2 in Tyrade, for the treatment of irrigation and foliar spry,
respectively.
The research aims to study the effect of certain organic and amino
compounds in the growth and production of tomato under green
houses conditions.Hulay F1 hybrid tomato and two organic
commercial vehicles differing in composition Hupost and
Boldo
uzerwere used.The experiment done in a way randomized
complete blocks designed , with three replicates per treatment , and
10 plants per replicate . Seedlings WERE Prepared in beet moss
using trays of Alstrepor inside the greenhouses.
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.
This search aims to study the efficiency of using“Biotolerance” as a
fertiliser; by a foliar spry on Pepper seedling. Four varieties were
used (Marcony, California wander, Maroty-7 andRobber). The
results showed that the treatment by the fertilizer resulted in an
increase in growth thorough the plant length increasing.
