This research was carried out through the 2012-2013 season on 10 years old, grafted on the rootstock B41,grapevines of Al-Hulwani cultivar. Three levels (10,20,40 t/ha) of organic fertilizers of cow, sheep plus and poultry were used, in addition to
three treatments from mixture of this levels (3.33,6.66,13.32 t/ha) for one type of the fertilizers. The research also included three treatments from mixture of mineral fertilization with (N,P,K) at the rate (1:1:1) by using urea 46%, super phosphate 46% and potassium sulphate 50% in three levels (100-200-400 kg/ha), in addition to the control without fertilization, to study their effects on Some quantitative and qualitative Characteristics of the grapevine cultivar Al-Hulwani. The results showed the following:
The use of organic and mineral fertilization gave in all levels and types superiority in all studied characteristics compared to the control.
Most levels of organic fertilization and its treatments are superior to mineral fertilization in all studied characteristics.
The first level of sheep plus (10 kg/ha) gave the better results in weight of cluster and quantity of product, but the first level of poultry gave the better results in weight of 100 fruits.
The use of organic manure was with positive effect on fruits color and was superior to mineral fertilization.
The yield/vine increased significantly from 65.77kg/vine to 118.5 and 97.8kg/vine when the low level of sheep puls the mixture of the medium levels of mineral fertilizers were used.
The research was carried out during the years 2010 and 2011. The results showed the
following:
The soil's care operations are carried out in the modern and middle old orange
fields and aren't carried out in the old fields ( more than 30 years).
The operations are
embodied in the cultivating operation (facial plowing). The plows are used only in the
modern fields to prepare the seed bed for planting some plants (agronomists) between the
trees classes.
The used plows were effected differently on the orange trees according to plowing
depth and machine sorts. By using the disk harrows with (8) cm depth appeared some roots
on the soil's surface. The trees roots were uprooted and cut up by using the chisel plow
with (20) cm depth and by using the mould board plough with (30) cm depth, but the effect
was so clear by using the mould board plough, that the most of the roots were hurt.
This research was conducted in plastic house in Zahed local for organic
agriculture in Tartous in two agriculture season during(2014-2015)
and(2015-2016) to study the effect of solid and liquid organic fertilizer from
digstate in some Physical and Chimical Characteristics of Tomato fruit
(hybride Nesma) in green house.
This research was conducted in plastic house in Zahed local for organic agriculture in
Tartous in two agriculture season during (2014-2015) and (2015-2016) to study the
effect of solid and liquid organic fertilizer from digstate on some vegetative
characteristics of tomato plant (hybride Nesma) in green house 10 treatments with 4
replicates.
