Abstract
Respect to this research study the response of some types of canola to
modern irrigation systems (trickle-Sprinkler) and using the densities of
various plant is in the distance between the injustice (10 - 20-30 cm) in the
desert lands in the new Research Station Shalatin of the Desert Research Center during the two seasons 2008/2009 and 2009/2010, it became clear that
the soil which made it look as sandy limestone (93.3% sand) and water used
for irrigation of the third degree where the proportion of salinity (1184 ppm)
that have been carried out the experiment in the winter season. It should be
noted that the amount of water disposal system for each of the irrigation
systems were based on measuring the difference between soil moisture. And
include all the experience of two variables, one species, where he studied two
types, one local, sero 4 and the second Imported from France, Bactul and the
second variable is the distance between the injustice on the same line which is
10.20, 30 cm and summarized the results obtained from this study are as
follows:
1- A seed yield and oil / acre: more than crop seed and oil at Plant Growing
canola under trickle irrigation system, compared to irrigation system
Sprinkler, and more than class canola local sero 4 imported counterpart Bactul
in crop seeds and oil per acre, also led Agriculture wide (30 cm
between unfair) to increase both crop seed and oil increased slightly when
compared to the distance the narrow (10 cm between the injustice), during the
seasonal study and the response has been great for crop seeds and oil feddan
when agriculture products canola sero 4, the results indicated field and
chemicals that interact triple between irrigation systems × species × distance
was significant during the two years of study as this indicates that the
interaction of access to BFH crop of canola seed and oil / acre in the desert
land, with an average yield of seed 1915.0 and 1935.0 kg/ acre for two
seasons 2008/2009, 2009/2010 Sort harvest was oil 802.4 and 830.1 kg / acre
for the same two years of study in the same order when growing canola
variety cypress four land sandy limestone under drip irrigation system
quantities water equivalent to evaporation - transpiration of a 1794.6 and
1794.3 m 3/acre for seasonal agriculture respectively. Here, it must be noted
that chemical analysis of water for irrigation has proved that it saline water
from the third class (1184 ppm). Means that the salt-tolerant canola plants to
extremes of high and agriculture in the sandy soil and limestone are given
either a high yield of seed or oil.
2- Percentage of oil in the seed: not affected by the impact of value to both class
and distance of Agriculture, while the trickle irrigation system for the
significant effect in increasing the proportion of oil compared to Sprinkler
irrigation system.
3- Three water consumption: The system of trickle irrigation the impact of a large
decline in water consumption for crop canola when compared to the system
Sprinkler irrigation, has proved the results obtained that the class sero 4 Least
consumption of water for irrigation of the class Bactul, this did not affect
plant spacing on water consumption for canola, this We would like to point
out here that the water consumption of the interaction of three and the abovementioned to produce the highest yield of seed and oil was 1794.6 and 1794.3
m 3/acre for two years of study, 2008/2009, 2009/2010, respectively, where it
represents the amount of water that resembles the evaporation - transpiration
only calculated actually follow the system of equilibrium moisture.
4- The efficiency of water use: canola resulted in trickle irrigation system to
increase efficiency compared to sprinkler irrigation, has also used local
cypress sero 4 to more efficient use of water as it hit 0.54 and 0.67 two years
of study, 2008/2009, 2009/2010, respectively when compared to jumping
into Bactul importer, which amounted to 0.39 and 0.47 for the same two years
of study in the same order, this did not affect the distances of agriculture in
this regard, the results indicate that the efficiency of water use reached 1.07
and 1.10 for the years Search 2008/2009, 2009/2010 respectively, and for the
interaction of the aforementioned trio, which gave the highest yield of seed
and oil /acre.
5- Through the use of mean changes to some of the variables shows that
economic class sero4 beats Bactul in class:
Average change in the amount of the main producer of seeds and oils, the
average change in the value of the main product, the average change in the
value of total revenue, the average change in the value of net returns, the
change in average water consumption of the seeds, the average change in the
efficiency of water use.
6- And at the discretion of the economic indicators sports conclude that the index
of total return on the pound of the costs of irrigation, the total return on the
pound of the cost of human labor used in irrigation, the total return on the
pound of the cost of automation is used in irrigation, the total return for the
unit of irrigation water, the productivity of the unit irrigation water, the
average amount of water required to produce a unit of production activity, the
cost of irrigation generating unit of production activity, the net returns per unit
land, net returns per unit of water, value added per unit land, the value-added
per unit of water has comparative advantage in the case of class sero 4 class
Bactul system of trickle irrigation and Sprinkler irrigation system and trickle
irrigation system is better than Sprinkler irrigation system, with regard to
index the unit cost of irrigation water has achieved a class Bactul relatively
low for an item sero 4 during regular trickle irrigation and Sprinkler, because
the water used in drip irrigation system less water used in sprinkler irrigation
system, which shows the high cost of irrigation in the case of trickle
irrigation.
