Ministry of Environment and Water
Selecting salt-tolerant date palm varieties for the UAE
In collaboration with the Ministry of Environment and Water
(MOEW), ICBA continued its long-term research in date palms that are a key
component of production systems in the Arabian Peninsula characterized by
drought and salinity stresses. The goal of this research is to identify
high-yielding, tolerant date palm varieties and improve crop management
techniques to maintain optimal functioning of the agro-production system and
survival of the plants under stress environments.
During 2011 date palm canopy attributes (plant height,
diameter, size and angle of the leaves and the fruiting branches) and yield
parameters were recorded for each local and imported variety reaching maturity
stage. Taking the experiment as a whole, there were significant variety,
salinity and variety x salinity effects for all parameters. Local varieties,
Shahla and Lulu, can be recommended for intermediate and highly saline water of
irrigation, respectively. Indeed, these varieties performed the same during the
previous years, thus showing inter-year stability. In contrast, varieties such
as Nabatet Sultan, Um Al Hamam and Ajwa-Tul-Madinah seemed to be slightly
adapted to the environment and showed high inter-year variation in yield.
In March 2011 ICBA was recognized during the Khalifa Date
Palm Awards when it was one of the eight winners chosen out of 131 regional and
international participants with its research on the potential of Arbuscular
Mycorrhizal Technology for Date Palms. The research was awarded second place in
the 1st category of Distinguished Research and Studies.
In another partnership with MOEW, ICBA contributed to
the successful conduct of the soil survey of the northern emirates as a member
of the technical committee.
DEMONSTRATING THE POWER OF SYNERGY
Farmers’ Services Centers
Enhancing water and food security in
the UAE
ICBA’s efforts in the United Arab Emirates will enhance
water and food security and enable adaptation to the impacts of climate change.
In a long-term collaboration with the Farmers’ Services Centre (FSC) – the
intermediary between ADAFSA and the UAE farming community - the ICBA scientific
team are researching improved varieties and non-conventional forages for
replacing Rhodes grass in the Western Region of Abu Dhabi Emirate, improved
farming management practices and developing capacity development for extension
services and farmers.
Recognizing that on-farm trials with
farmers’ participation will speed up the selection and introduction of new crops
to diversify the production systems, the ICBA/FSC team developed farms, which
had been selected after a survey and soil and water analyses by ICBA, at two
levels: (i) Demonstration; and (ii) Model. The Demonstration farms were
developed in small areas of 0.5 donums (0.05 ha) to represent different
agricultural regions (Liwa, Madinat Zayed and Ghayathi) and different salinity
levels (low 5-10, moderate 10-15 and high 15-20 dS m-1 and above).
Three Demonstration farms were
planted with different accessions of five winter forages (barley, fodder beet,
safflower, mustard and quinoa) during October 2010 and continued up to February
of the current year. The summer trial was carried out during May, using
salt-tolerant varieties of sorghum, pearl millet, guar, cow pea and sesbania in
all of the three Demonstration farms; crop were irrigated using water of
salinity levels varying from 15.4-17.7 dS m-1.
The Model farms, ranging from 23 to
40 donums (2.3-4.0 ha), were also proposed for the same regions and salinity
levels, but on the whole farm-level (excluding date palm growing and livestock
areas). The ICBA team prepared the planting and irrigation layout and measured
soil salinity for the model farms for the three regions. After commissioning the
irrigation systems in Madinat Zayed and Mezaira’a, four perennial salt-tolerant
forages (Paspalum vaginatum, Distichlis spicata, Sporobolus virginicus and S.
arabicus) were planted. These grasses were established at ICBA headquarter under
field conditions and acclimatized with irrigation water of 30 dS m-1. For transplanting,
grass strips of 50 cm were removed with the soil, rolled and transported to the
Western Region. The grasses were split with root systems and transplanted in the
field.
Improving management practices leads to increased productivity in
Iraq
The Australian Centre for International Agricultural
Research (ACIAR) is funding a partnership between the International Center for
Agricultural Research in the Dry Areas (ICARDA), International Water Management
Institute (IWMI) and Iraqi representatives. The scope of the collaboration is to
address the salinity problems impacting on agriculture in central and southern
Iraq; however, trial sites have been established in similar areas in Syria.
ICBA’s role in the project is to focus on crop improvement and production system
management at the farm-level and as well supplied germplasm of salt-tolerant
plants.
During the year, two trials were initiated at mirror sites in Deir-Azzor
and Al-Dujaila in Syria.
- Activity E1(B) and E2 evaluated summer forages (sorghum and
pearl millet – ICBA-supplied salt-tolerant varieties and two local varieties),
sesbania, guar and cowpea at Al-Dujaila (Wasit) at the salinity range of 10-20
dS m-1.Activity E1 researched the impact of salinity and
boron content of irrigation water on the growth of winter cereals (wheat and
barley) in Deir-Azzor in Syria as part of the Mirror Trial in Iraq. The trial
focused on the need to improve production in wheat and barley cropping systems
in soils with ECe values of 10-20 dS m-1. Preliminary results show that the
plants exposed to the highest level of salinity indicated symptoms of boron
toxicity on the first leaf of two of the cultivars of the tested crops, and the
damage was greater for barley than wheat.

The growth of these crops will be monitored during the trial. Additionally
soil samples have been taken from five locations for two depths (0-50 and 50-100
cm) to determine the soil salinity. Ground water salinity is monitored monthly
through peizometers at two locations.
By assessing the salt distribution and its drivers, irrigation water
salinity at different levels (farm, irrigation district, and river basin) at
representative sites such as Wasit (Al-Dujaila), Babil (Al-Musaib), and Basra
(Abu Al-Khaseeb), the research will inform methodologies for salinity control
and productivity enhancement of saline water and salt-affected soils. In the
long-term funding of additional research and mitigation strategies could be
provided by ACIAR and a broader set of interested donors.
Enhancing crop-livestock productivity through the use of sorghum
and pearl millet in WANA
Saline soils cover 5-10% of the world’s arable land; a
percentage that continues to expand. Salinity is a major constraint to crop
production, especially in the arid and semi-arid regions of the world, where low
precipitation, high surface evaporation, irrigation with saline water, rising
water tables, and poor irrigation practices generally increase the levels of
soluble salts. A strategically important objective is to improve forage yield in
harsh environments where the salinity of irrigation water is increasing
constantly. Crop options provide less expensive, more sustainable solutions for
enhancing the crop-livestock productivity of salinity-affected lands.
Both pearl millet and sorghum are two main fodder crops in
the MENA region that have the potential role to fill the gaps in farm
productivity and in a crop livestock system. In many salt-affected areas with
reduced potential for the production of high value cash crops, the most viable
option is to shift production to a forage livestock production system that can
maintain farm productivity and improve income through the integration of forage
production and a livestock system. Defining the salinity tolerance of pearl
millet (Pennisetum glaucum (L). R. Br.) and sorghum (Sorghum bicolor L. Moench)
and establishing crop management systems can facilitate more productive and
eco-efficient agriculture. The current project is a major selection program
where ICBA and ICRISAT are following similar environments of selection on a
large amount of genetic diversity. Through extensive screening and evaluation of
more than 800 landraces, breeding lines, and varieties of the two crops for
salinity tolerance and yield potential (both grain and fodder) under various
levels of irrigation water with salinity up to 15 dS m-1 (11,000 ppm), a nursery
of each crop species containing 2530 genotypes with high potential for yield
under saline conditions was identified and distributed to partnering countries.
The achievements in phase I in Egypt, Jordan, Oman, Syria
and Tunisia have laid the foundation for larger on-farm trials, increased seed
production, release and adoption of identified high-yielding and
salinity-tolerant sorghum and pearl millet varieties and also set up the
efficiency of genetic improvement for salinity tolerance for Phase II. During
the second phase, ICBA, ICRISAT and the NARS Egypt, Jordan, Oman, Syria
and Yemen have achieved the following:
Seed production and distribution
Based on ICBA and NARS evaluations, promising entries of
twelve pearl millet and nine sorghum were selected. Six pearl millet and two
sorghum entries were multiplied at ICBA and distributed among NARS for further
seed multiplication and distribution among local farmers in each country.
Selected genotypes were grown in isolation at ICBA and these produced 150 kg of
sorghum and 260 kg of pearl millet seeds. Multiplied genotypes were distributed
to NARS for adaptation studies under various environments of the WANA region.
This new collection was also sent to NARS for on-station and on-farm
evaluations.
Partnering countries extended considerable efforts in seed
multiplication and field evaluation of all the plant materials provided by ICBA
and ICRISAT. Scaling-up and farmers’ participation increased during 2011 to
reach the target of 50 farmers in each country. Farmers participated in
establishing the selection criteria and identifying the most promising genotypes
for their targeted environments and field salinity levels. Genetic diversity of
the newly introduced genotypes was equal to 60% and 90% for sorghum and pearl
millet, respectively. Biological yield recorded was on average 50% higher for
pearl millet compared to sorghum species. Indeed, averaged across all tested
salinity levels, the advantage of pearl millet over sorghum were 18% higher leaf
area and 25% heading beginning earlier. The best performing genotypes identified
in the NARS showed high early vigor which allowed them to have high potential
yield. This advantage found in controlled conditions was confirmed in field
experiments and in on-farm trials. The average crude protein was equal to 13.5%
which was within the acceptable level of forage quality for both species.
On-farm evaluation
Selected genotypes were assessed for forage productivity
and quality in a series of 23 on-farm trials covering c.a. 30 ha over two
growing seasons. The farmers’ survey covering 70 farmers showed that introducing
salt-tolerant forage into the farmers' cropping systems improved the farming
income by 20–30% compared to conventional practices. Harvested salt-tolerant
fodders, cultivated using saline water, were analyzed to determine nutritive
quality. Indeed, the harvested plants were intended to feed small ruminants. Two
animal feeding experiments were set up in order to compare feed intake, growth
performances, carcass characteristics and animal reproduction of indigenous
lambs fed diets containing various levels of hay and silage of salt-tolerant
pearl millet genotypes. Accordingly, a series of on-farm trials and lamb feeding
experiments served as demonstration support for farmers.
Optimization of crop management systems
Optimization of crop management systems was achieved
through a series of 10 field experiments across all countries with the aim of
integrating diverse farming conditions as a parameter in the study. Crop
management systems tested included various sowing densities, irrigation systems
(furrow, drip, gated pipes and sprinkler), cutting systems (number and height),
nitrogen and potassium fertilization (total amount to be applied, timing of
applications, chemical formulation and physical form) and intercropping systems
with annual crops and shrubs. Optimum levels of many input factors have been
determined and are being transferred to farmers in the targeted regions.
Improving Integrated crop and seed production systems in SSA
An inter-disciplinary approach to improve the performance of small-scale
irrigated farming systems of Sub-Saharan African (SSA) countries (Burkina Faso,
Gambia, Mali, Mauritania, Niger, Nigeria and Senegal) should consider water
quantity and quality, irrigation technologies/management, crop diversification,
appropriate soil, water and nutrient management practices, and rural
socio-economic aspects such as market linkage and value-chain development.
The multiple benefits for the SSA countries generated from such an approach
would include improved sustainable agricultural production, improved water
management for seed production for commercialization and diversification. By
achieving a dependable supply of basic agricultural products, food security will
be improved and sub-optimal migration from the farming communities minimized.
The NARS of the seven SSA countries, the Islamic Development Bank and
International Center for Biosaline Agriculture (ICBA) launched the endeavor in
October 2011 in Dakar, Senegal. This four year project of US$1.2 million (IDB
grant) with a contribution of US$0.8 million from the NARS has started in
November 2011. The key outputs include (i) water resources database developed,
(ii) Appropriate irrigation technology (ies) are identified, tested and
transferred, (iii) packages of diversified crops indentified, demonstrated and
evaluated, (iv) sustainable seed production for improving agricultural
production, (v) profitability and impact of crop production related to different
water/irrigation management practices on the livelihood of poor farmers assessed
and quantified, and (vi) technology transfer and capacity building. During the
first six-month, the project made a good progress, against agreed work plan, in
data collection, testing and demonstrating some technologies in some countries,
and a limited capacity building activities.
Developing sustainable water, rangelands and livestock management
in CAC
Crop diversification and sustainable management of marginal land resources
in three Central Asian countries (Tajikistan, Kazakhstan and Uzbekistan) is the
focus of a four-year partnership involving ICBA, ICRISAT and ICARDA commencing
in 2011.
To improve land productivity and livelihood of poor farmers living in
salt-affected and degraded areas, dual-purpose pearl millet (Pennisetum glaucum
[L.] R. Br.) and sorghum (Sorghum bicolor [L.] Moench), two highly productive,
nutritional early spring and summer crops, were introduced to fill existing gaps
in grain and forage production in the Central Asian region. Socio-economic
studies to provide sound costs/benefit estimates for all interventions, under
realistic conditions of small farms, will be conducted.
In the second stage of desk studies the project team will evaluate the
necessary institutional and legal changes to allow for production and marketing
of sorghum and pearl millet by products. These measures will benefit small,
remote, rural communities with limited land/water resources to ensure
sustainable land use and provide additional income. Collaboration with farmer
associations and the National Research Systems will guarantee implementation,
whereas collaboration with academic research institutions will ensure the
necessary data acquisition to allow out-scaling of project results to other
Central Asian and Caucasus countries.
A Project Inception Workshop was held in Uzbekistan during June 14-16,
2011 to discuss the work plan and finalize first-year activities to commence
July 1, 2011 in 2-3 sites in each country.
The seed of sorghum and pearl millet were produced by ICBA in
collaboration with ICRISAT and sent to the CAC partners. In addition, local
varieties of the same forage crops were also included in the trial.
Improving Livelihoods of Rural Communities in Saline Desert
Environments
Extreme drought and high temperature extremes coupled with
rapid expansion of irrigated agriculture and intensification of human activities
have severely impacted the dryland ecosystem of Turkmenistan. These impacts
include major deterioration of the fertile arable lands, natural pastures,
riparian and foothills forest leading to desertification including soil
salinization and waterlogging; a situation exacerbated by climate change.
Currently huge areas of long-term irrigated agricultural lands and sandy desert
rangelands in Turkmenistan have deteriorated into marginal salinized/waste
unproductive lands. The availability of fresh irrigation water in these marginal
areas has inevitably declined because of increasing demand from agricultural and
non-agricultural users.
Partnering with the Institute of Desert Flora and Fauna and
Ministry of Nature Protection, in Turkmenistan, ICBA investigated in 2011 the
efficiency of non-conventional water use in agri-silvi-horticultural and
silvi-pastoral systems to meet the food and feed demands and develop adaptation
strategies for farming communities vulnerable to climate change and water
resources shortage. For farmers to generate additional income, the project team
considered alternative uses of land such as the reclamation of marginal lands by
using non-conventional water for irrigation (drainage, surface rainfall water,
salinized underground water) and the introduction and evaluation of biosaline
technologies.
Located in the Amudarya River Delta, Dashauz region,
Northern Turkmenistan, the Dashauz Experimental Plot typifies newly irrigated
sandy desert land, which is severely affected by salinization, with a shallow
water table (141-182 cm) and low quality surface water (11-20 dS m-1) available
for irrigation.
The seeds of 14 salt conventional and non-conventional
tolerant crops were sown during May. Seed germination of about 68-72% was noted
for flux, chickpea, holy clover, alfalfa, and Amaranthus. Tests of sorghum
germplasm from ICBA accessions showed significant advantage both in seasonal
growth rate and plants’ height in comparison with the local variety. The pearl
millet germplasm from ICBA exhibited about 30% more dry yield and 25% seeds than
local varieties. The analysis and monitoring of soil salinity, water table
depth, irrigation and drainage water quality is being continued.
At the Akdepe site, promising results from the farm
evaluation were obtained for ICBA dual-purpose sorghum (4 varieties), pearl
millet (4 varieties) and two (Eureka and Sceptre - third generation) alfalfa
varieties as compared with local varieties.
