This study considers the efficiency of irrigation water usage in the
economic and productive aspects of peanuts crop in Syrian lands, in
particular: mid, coastal and eastern lands, in terms of arithmetic
means during the period of 2010-2012.
This research on pepper crop conducted to impact water stress using
three transactions water are: full irrigation (100% from water
requirement), 0.75% of full irrigation, and 60% of full irrigation,
has been designed experiment in a way random sectors full, use a
variety of municipal plant peppers, and used drip irrigation method.
A field trail was conducted at Jeleen Research Station, Dara,a governorate,
Syria, during two consecutive growing seasons (2010/ 2011-2011/ 2012), in
order to evaluate the role of some cultural practices in improving nitrogen use
efficiency and gr
ains quality characteristics of four wheat varieties (Acsad1105,
Acsad1229, Acsad885 and Acsad901). The experiment was laid according to
randomized complete block design-split, with three replicates. Leaf area index,
grain starch content and grain yield were significantly higher during the first
growing season, in the wheat variety (Acsad901), for the first planting date, and
nitrogen rate (200 Kg N. ha1-), when nitrogen fertilizer was added in two splits
(1.25, 68.60 %, 1051 g. m-2).
Objective of this work was to investigate how plant density and nitrogen
rate affects the growth , yield and its components in maize (Bassel 2 hybrid).
The experiment was carried out, at the agricultural research centre in Snoubar
Jableh, during t
he 2008 and 2009 seasons, included 12 treatments which were
the combination three plant population densities 71428/ha, 57142/ha, and
47619/ha and four N rates (0, 60, 120 and 180 kg/ha). The experimental design
was a split-plot, with different densities as main plots, randomized in three
complete blocks, and the fertilization as subplots. The data were analyzed by
using “Mstat” statistical package. Increasing planting population density
delayed anthesis and silking date, increased the anthesis-silking interval, plant
height, ear height, grain yield, agronomic nitrogen efficiency and nitrogen use
efficiency, but decreased ear leaf area, chlorophyll content, 1000 seed weight,
number of grains/ear, shelling percentage (%), and grain protein content.
Nitrogen fertilizer decreased tassilling and silking date, and nitrogen use
efficiency, increasing plant and ear height, ear leaf area, chlorophyll content,
number of grains/ear, ear weight,1000-grains weight, Shelling percentage,
grain yield up to 120 kg N/ha, agronomic nitrogen efficiency and grain protein
content.
This research was conducted to determine the most responsive phenological
stage for supplementary irrigation of the durum wheat in a primary stationary
region.
It consisted of six different water treatments in addition to control (non
irrigated)
:
1-From planting to seedling emergence; 2-From planting to tillering; 3-From
planting to booting; 4-From planting to flowering; 5-From planting to the end of
the milk stage; 6–Sowing irrigation and irrigation according to necessity
throughout the milk stage.
The study has been repeated in four blocks for three seasons from 2002 to
2005. The results of the first two seasons showed that the:
The treatment from planting to booting, was canceled because of the rain and
soil dampness during this growth period. A significant increase in production,
water use efficiency, and one 1000 kernel weight, of both 5th and 6th treatments was
noticed in comparison with other treatments and the control. Results of the three
seasons were varied due to the environmental variation in temperature and amount
of rainfall.
This study was conducted at the Faculty of Agriculture, Damascus
University, during two seasons (2002-2003) to assess the effect of irrigation
methods (drip, sprinkler, furrow) of maize (Gota 82). The results showed
significant differences between
irrigation methods in grain and green weight
production (average of two seasons, for grain: 6.48 t/ha,6.065 t/ha, and 7.905
t/ha for drip, sprinkler and furrow irrigation respectively, and for green
weight 24.4t/ha, 22.04t/ha, and 25.75t/ha for drip, sprinkler and furrow
irrigation respectively).Concerning total water requirement, drip irrigation
method was the lowest one (average of two seasons, 4392.87m3/ha) followed by
sprinkler irrigation (5565m3/ha) compared with furrow irrigation
(9011.92m3/ha).
Chickpea (Cicer arietinum L.) in the Mediterranean climate can experience
two types of drought: intermittent drought stress and terminal drought stress.
A study was conducted during early August 2002 to early April 2003 under
glasshouse conditions
, to study the response of six chickpea genotypes, four
Kabuli and two Desi, to soil moisture levels.
