Translated Indian Pistachio Health Benefits Factsheets

Why should nuts, including pistachios, be part of a healthy daily diet?
Decades of research has highlighted the significant health benefits of nuts.
A recent scientific review[1] found that eating a handful (28g) of nuts a day, compared to eating
no nuts, was associated with:

  • ↓ 25% reduced risk for coronary heart disease
  • ↓ 22% reduced risk of death from cardiovascular disease
  • ↓ 22% reduced risk of dying from all causes
  • ↓ 21% reduced risk for cardiovascular disease
  • ↓ 11% reduced risk of dying from cancer.

Turkiye’s Pistachio Report for the Current Season.

Turkiye’s pistachio production in Marketing Year (MY) 2023/24 is forecast at 160,000 metric tons (MT). Production volumes will decrease compared to the previous MY since MY 2023/24 is considered an “off-year” in the production cycle for pistachios. Still, production will not be as low as some of the earlier off-years. Production will be buoyed by an increase in the number of bearing trees. According to the Turkish Statistical Institute (TurkStat), there were an estimated 58 million bearing pistachio trees at the beginning of the current marketing year, up nearly 5 percent from last year. There are also about 25 million non-bearing trees, which is about 7 percent higher than a year ago.       Read the report here (PDF):  Tree Nuts Annual_Ankara_Turkiye_TU2023-0030

Summer and Pre-Harvest Seasonal Notes are available.

Dr Ben Thomas has produces the first of the ‘Seasonal Notes’ for 2022.

We are now in the nut fill period of the pistachio production cycle which is a critical phase of the pistachio production cycle when the kernel grows and causes the shell to split. Good management during this phase will maximise kernel growth and shell splitting. Key issues at this time are understanding kernel development, managing irrigation and nutrition and preparing the orchard for harvest. This is also the time for leaf analysis and budding young trees.

Chill Newsletter Number 4, final for 2021, September 2021.

The PGAI Chill Newsletter no. 4, the final report for the 2021 winter season is available, outlining the dynamic chill unit accumulation in different Pistachio growing locations in Victoria, New South Wales, and South Australia.  The data has been prepared by Dr. Jianlu Zhang and PGAI’s new Researcher Dr. Maha Mahadevan.

Records show insufficient chill accumulation for 2021 season (1st March to 31st August) in few pistachio growing regions, particularly the Riverland in SA and Sunraysia in VIC. This would potentially impact pistachio production for the season.

Key information :

  • Riverland did not reach 59 Dynamic Chill units requiring growers to take up mitigation action such as oil or polymer sprays.
  • Sunraysia showed sufficient Dynamic chill units, however, had below average hours less than 7 degrees Celsius (alternate model for chill requirement)

A survey has been set up to collect and compile information on the actions taken to mitigate the issue, the impact it has on uniformity, earliness of bud burst, flowering, and nut set ultimately yield and quality. Capturing and uploading photos would be a great visual representation.
Provision has been provided to upload photos.

This will be a highly valuable information that will help understand and model low chill mitigation practices specific to a geographical location, its interaction with weather parameters and response of the pistachio trees. It will assist develop robust and efficient mitigation strategy through future research.
Thank you in advance for taking up the survey: Click here to access the survey: Chill Survey 2021

The Final Chill Newsletter Number 4 can be downloaded here:  Chill Newsletter No4_20210920

Chill Newsletter Number 3 August 2021.

This gives growers valuable information to determine chill mitigation actions over the coming weeks.
We would make the following additional comments:

  • The Riverland is most unlikely to receive sufficient chill this season. Riverland growers should be considering taking mitigating action with oil sprays at the higher concentrations and the higher application rates.
  • The situation in Sunraysia is not clear. The Dynamic model shows sufficient chill for Swan Hill but border line for Mildura/Merbein. The alternative chill model of <7OC shows insufficient chill for all of Sunraysia. Growers need to consider their own orchard most carefully.

If you require any additional assistance please do not hesitate to contact relevant people within the Industry.

Winter chill to the end of July continues very mixed. The main growing areas of Sunraysia and the Riverland are continuing to be having below average chill with a high risk of not achieving sufficient chill to the end of August, the eastern end of the growing area such as Griffith and Wagga Wagga are enjoying above average chill.

Media Release – ANAO assessment of the department’s response to biosecurity non-compliance – 7 June 2021

The ANAO has completed an audit to assess the Department of Agriculture, Water and the Environment’s effectiveness in responding to non-compliance with biosecurity requirements. The department agreed to all eight recommendations in the ANAO report.

Head of Biosecurity at the Department of Agriculture, Water and the Environment, Andrew Tongue, said the report identified timely recommendations to improve the department’s arrangements to respond to non-compliance with biosecurity.

“Although Australia’s current biosecurity system has served our country well, the department recognises that the system must continue to evolve to enable appropriate management of known and emerging threats both domestically and globally,” Mr Tongue said.

“Prior to the audit, the department had already commenced a body of work to enhance its compliance arrangements and regulatory practice.

“In particular the department is undertaking a range of changes and improvements through the development of its Regulatory Practice Statement and Regulatory Practice Framework.

“We are committed to protecting Australia’s biosecurity status and our agricultural industries by minimising the entry of new pests, diseases and weeds and regularly making improvements.

“The Australian Government’s significant investment in its Biosecurity Package in the 2021-22 Budget and the recently released Commonwealth Biosecurity 2030 will further position the department to address the audit findings.

“The Budget investment will boost our frontline people and resources, strengthen our partnerships with industry and the community, and modernise our ICT systems, technology and data analytics to better target risk and speed up clearance times.

Commonwealth Biosecurity 2030 will help the government build a stronger, smarter biosecurity system.

“Through addressing growing biosecurity risks and making sure we have the best controls, tools, processes and networks in place into the future we can continue to safeguard Australia’s agricultural industries, environment and exports.”

Merry Christmas and a Happy New Year to all PGAI Members

2020 was indeed a difficult year with the pandemic figuring prominently – tempered by a generally good harvest and a thriving industry.  However, I’m sure many of us will be pleased to see the end of 2020!  To that end from PGAI and the Committee, may you all have a Very Merry Christmas and a Happy and Safe New Year.  Here’s to time spent with family and friends, good cheer and a successful 2021!

Minimising drip system drainage

Drip irrigation has become the standard irrigation system adopted for irrigated horticulture. Most irrigators are generally operating at a high level of efficiency.  Recent observations have highlighted that drip irrigators can achieve even greater efficiencies by addressing system drainage (often referred to as ‘drain-out’).  Reducing the level of system drainage will result in a more even water application, a reduction in localised rootzone waterlogging and crop productivity loss.

Agriculture Victoria has produced a 6 page document on the hows and whys and can be found here:   Minimising drip drainage

Alternatively, you can find this paper and further information on the Irrigation Management page in the members section –  Pistachio Production Puzzle

Dr Ben Thomas has provided the latest in his seasonal reminder series.

We are now in the nut fill period of the pistachio production cycle which is a critical phase of the pistachio production cycle when the kernel grows and causes the shell to split. Good management during this phase will maximise kernel growth and shell splitting. Key issues at this time are understanding kernel development, managing irrigation and nutrition and preparing the orchard for harvest. This is also the time for leaf analysis and budding young trees.
• Kernel development. During the nut fill period, the kernel within fruit start to grow and fill the shell. The start of this period varies each season and flowering and fruit set was variable this season for many growers. As such, understanding the range of kernel development is very important when considering irrigation and fertiliser applications as well as being very valuable when estimating the start of harvest.

Agriculture, water and environment – a positive move for Australia

The changes to departmental structures announced by Prime Minister Scott Morrison today will strengthen the Government’s ability to deliver effective policy outcomes across agriculture, water and the environment for all Australians.

Environment, water and agriculture are inextricably linked across regional and rural Australia and metropolitan centres.  Bringing together the environment and agriculture departments will provide greater synergies to the policies and programs that underpin regional Australia and our agriculture, fisheries and forestry industries.  Managing our natural environment, our water, our land, our soils and air together makes sense.  Farmers and our agricultural industries are at the frontline of Australia’s conservation and environmental efforts. We look forward to working even more closely together to deliver a practical environmental agenda that delivers for our farmers, who manage more than 50 per cent of Australia’s land mass and which supports the Morrison Government’s national environmental agenda.

We wish to sincerely thank outgoing Agriculture Department Secretary Daryl Quinlivan for his many years of outstanding leadership and tremendous policy advice. Daryl has been a dedicated and utterly professional public servant. We look forward to working with the new Secretary of the Department of Agriculture, Water and Environment, Mr Andrew Metcalfe.

This is a merging of departmental resources, not portfolios. From a portfolio perspective each minister will maintain their own policy objectives.

Best practice biodiversity management front and centre

The Liberal and Nationals Government is delivering on an election commitment to explore the need and current tools available to farmers that could turn their natural resource management into increased profits.

Minister for Agriculture, Senator Bridget McKenzie, said the National Farmers’ Federation (NFF) was looking at the positive environmental contributions in the agriculture supply chain under the $4 million Australian Farm Biodiversity Certification Scheme Trial. “The use of sustainability standards has the potential to boost farm incomes if farms are certified as achieving high environmental standards,” Minister McKenzie said.

“Our farmers are our nation’s greatest environmentalists—they care for more than half of our land mass.  “It makes sense that farmers’ good practices are recognised as consumers demand more information about how the food they eat and the fibre they use is produced.

“This project is about making sure that any certification or verification scheme delivers benefits for farmers and means something for consumers. “The NFF will work with farmers to develop and showcase innovative examples of best practice biodiversity management of natural resources.

“It will research existing schemes, sustainability frameworks and best management practices, and will also assess the readiness of farmers to participate in schemes. “The NFF will also work with farmers on how plant and animal pest management practices can deliver productivity improvements.  “The scheme is part of the Agriculture Stewardship Package—a $34 million election commitment that aims to integrate productivity, sustainability and biodiversity on farms to provide lasting benefits to farmers and community.”

Demand for pistachios is going nuts giving growers good reason to smile.   ABC News online article 14/04/2019

Despite expanding their orchard Martin and James Simpfendorfer cannot keep up with demand.  Photo courtesy ABC Rural: Jessica Schremmer.

A cold winter and hot summer has given pistachio growers good reason to celebrate, with many farmers harvesting great volumes despite being in the “off-year” crop cycle — and demand for the green nut is rising rapidly. Robinvale pistachio grower and director of Australian Pioneer Pistachio Company, Chris Joyce, said looking at the two-year average the industry was doing well and growers were confident.

“Pistachios are an alternate-bearing crop, so one year they have a big crop and the next year they have a much lesser crop,” he said. “In 2018 we had a record crop and in 2019 we had the inevitable off-crop, significantly less than the previous crop.   Read the full article here:  Pistachios_Simpfendorfer_12_04_2019

The May 2019 Task List for Pistachios by Bob Beede, University of California farm advisor now available.

The latest task list for pistachios by Bob Beede. Even though the Caliufornians received good winter chilling this year, the cool spring weather has delayed pistachio leaf out and bloom by five to seven days. This spring is a great example of how, even with good chilling, pistachio plant development can be delayed by cool temperatures.

Announcement on Biosecurity Steering Committee – 5th March 2019

Minister for Agriculture David Littleproud has announced the chair and members of the biosecurity levy steering committee.

The committee contains representatives from industry and farm groups to help steer an informed delivery for the levy, which will see importers pay for biosecurity border screening.

The Chair will be Mr David Trebeck. Mr Trebeck currently chairs Australia’s Oyster Coast Ltd and has been a non-executive director of six ASX-listed companies since 1997, including GrainCorp Ltd (13 years) and Incitec Pivot Ltd, and has been involved in shipping since 1974. 

He was a non-executive director of the shipping company, AP Moller Maersk, a National Water Commissioner, director of the Australian Meat and Livestock Corporation and contributed to the Commonwealth Government inquiries into Long Term Policy for the Agriculture and Food Sector, Fuel Taxation, Biosecurity and three Commonwealth Fisheries. He also worked with the National Farmers Federation from 1972-1983 and co-authored the Beale Review into biosecurity in 2008.

The steering committee will also include Paul Zalei from the Freight Trade Alliance; Margie Thomson from the Cement Industry Federation, Mike Gallacher from Ports Australia, Mike Sousa from Qube Holdings, Rod Nairn AM from Shipping Australia, Brian Lovell from the Australian Federation of International Forwarders, and Tony Mahar from the National Farmers Federation.

“Australia’s border biosecurity protects our food supply, 300,000 jobs, the $60 billion agriculture industry and our way of life,” Minister Littleproud said.

“If our border biosecurity is breached and say foot and mouth disease entered Australia, consumers would pay much more for meat and the losses to farmers would be around $50 billion. 

“Those creating biosecurity risk should contribute fairly to addressing that risk, remembering pests and diseases arrive on the hulls and decks of ships and not just in the imported product itself. 

“If the taxpayer alone bears the burden of protecting Australia then companies being bailed out by the taxpayer are unlikely to take our biosecurity seriously.” 

Minister Littleproud said he was also glad Joel Fitzgibbon has put the following on record:

‘Labor supports the rationale for the biosecurity levy. Labor is committed to a properly funded biosecurity system.’

PGAI Seasonal Notes for January 2019 by Dr Ben Thomas.

We are now in the nut fill period of the pistachio production cycle which is a critical phase of the pistachio production cycle when the kernel grows and causes the shell to split. Good management during this phase will maximise kernel growth and shell splitting. Key issues at this time are understanding kernel development, managing irrigation and nutrition and preparing the orchard for harvest. This is also the time for leaf analysis and budding young trees.  Read more here: Seasonal Notes_January 2019

Managing the risks of working in heat from Safe Work Australia.

Working in heat can be hazardous and can cause harm to workers. The human body needs to maintain a body temperature of approximately 37 degrees Celsius.  If the body has to work too hard to keep cool or starts to overheat a worker begins to suffer from heat-related illness.  This guide produced by Safe Work Australia shows you how to manage the risks.   Download the guide here: guide_for_managing_the_risks_of_working_in_heat_1

Latest US Chill paper by Dr Louise Ferguson and others.

California growers in the San Joaquin Valley believe that climate change will affect
the pistachio yield dramatically. As the central valley fog disappears, insufficient dormant chill
accumulation results in poor flowering synchrony, flower quality, and fruit set in this dioecious
species. We have developed a novel, user-friendly, and low-cost Voice-Controlled Wireless Solid Set Canopy Delivery (VCW-SSCD) system to increase bud chill accumulation with evaporative cooling on sunny (winter) days.

The paper can be found in the PGAI Chilling Requirements page here

Merry Christmas and Happy New Year

Another year draws to a close and a new one about to start.  Overall it has been a great year for the Australian Pistachio Industry and on behalf of the PGAI I would like to wish you all a very Merry Christmas and a safe, happy and prosperous New Year!  Please take care over the Christmas – New Year period.  See you all in 2019!

Workplace Health and Safety

You may not realise it but farming is one of the most dangerous occupations in Australia. Only one in 10 workplaces are farms, yet they account for one quarter of all work-related deaths. Children under 15 years and adults over 65 years are more likely than others to be injured or killed on farms. Males are more likely to be injured than females.

You can reduce the risk of farm injuries and illness at your farm by evaluating the risks and taking steps to minimise them. Accidents can be prevented through better farmer education, making sure equipment is well maintained and has adequate safety features, having safety procedures in place, and training every worker and family member about potential dangers and the proper, safe use of equipment and machinery

NEW- QLD Gov/HIAL Online Chill Calculator

This site accesses daily weather station data for the period 1968 to the current year for 600 locations across Australia. This data is used to make calculations for the accumulation of winter chill and growing degree days/hours.

Because the chill and growing degree day calculations are based on weather data from the Long Paddock SILO, the calculations can only be updated when the weather data becomes available. The weather data from yesterday is usually available after about midday (AEST). The Long Paddock SILO uses data form the Bureau of Meteorology and patches this to create complete daily data sets. Stations that no longer record temperature data are synthetically in-filled with gridded data derived from statistical analysis.

All calculations are performed using the chillR package of Luedeling et al. (2013) & Luedeling (2017).  The website has been developed by the QLD Government in conjunction with Hort Innovation.

Pistachio Irrigation Research Paper by Louise Ferguson et. al.

Sustainability of pistachio production (Pistacia vera L.) under supplemental
irrigation in a Mediterranean climate.   The paper looks at the effects of supplemental micro-irrigation in a commercial rainfed orchard.  Irrigating with 10–15% of estimated full evaporative demand significantly increased average annual productivity by increasing yield in the on-crop year of this alternate bearing species. Irrigation increased yield by 30%, resulting in 1600 kg of in-shell product per ha.  You can download and read the research paper here:  Marinoetal2018
