Meet the people behind the crops: Netta Doitch

In Hazera, we tend to put the spotlight on our successful products, yet their success starts with the People of Hazera: the truly committed and passionate experts who make it all happen on a daily basis. Meet Netta Doitch (43), our Global Lead Tomato Breeding from Mefalsim, a small Kibbutz in the southern part of Israel. It seems as though it was meant to be- the daughter of a flower and strawberry farmer, Netta (meaning “a young plant” in Hebrew), was destined for a life in agriculture.

When she was young, she gladly helped her dad around the farm and without knowing it performed “cuttings” from a very young age, removing a small part of the plant’s stem, and replanting it together with a “rooting hormone”, to receive a genetically identical plant. “I always enjoyed agronomy and loved visiting agricultural events. When I was in high school, I recall reading in the newspaper about a successful “breeding” of red and blue bananas and decided, even though I did not know what “breeding” was, that this is what I wanted to do for a living. Netta went on to get her Bachelor of Science in Agriculture with specialization in Genetic Breeding and Biotechnology and later fulfilled her dream to become a breeder, doing so with a true feeling of love and chosen destiny.

Netta has been with Hazera since 2009, when she started out as Tomato Breeder Assistant. Two years later she became an Associate breeder and led the determinate heat set tomatoes and indeterminate round open field tomato projects. Approximately 12 years later, she is now, the Global Lead Tomato Breeding; and amongst her many projects she also leads the breeding projects of the Indeterminate Round Open Field (IROF) tomatoes.

“What is a common myth or preconception about your job or field of expertise?”

“It seems as though everybody believes that breeding ruins the taste in vegetables”. Nowadays she just explains to whoever asks that she works in Tomato Genetics without transgenic interference.

“In your opinion, what is the most important personality trait/strength someone would need to work in your industry/be successful in your job?”

According to Netta, being a good breeder requires super focus on the goal, you have to ‘breathe’ breeding every day, the plant dictates your work and not vice versa. Netta also highlights the constant change of environments in a breeder’s life: “You can say that I wear two hats: “In winter, you can find me all neat and dressed up in office clothing, whereas in summer you could hardly recognize me, as I’m all covered in plant parts, soil, and remains of tomatoes.” In other words, you have to be highly adaptable and “passionate” about your field of work.

“Tell us about a project you’re really proud of and why”

“I’m really proud of our Giga tomato, part of the IROF project in Brazil. When examining where we started and where we are at today, it is truly amazing!”. In the beginning of the project, we started out with zero resistance but very strong and vegetative plant genetics. The genetic change and adding the required disease we achieved was truly significant. The variety Giga in Brazil has excellent firmness, size, and unique array of resistances.

We went from totally “burned” plants, changed the selection method and started doing selections in the region, which was a major change in the way we work.

For more than ten years, together with Arno Van Staden, Tomato Regional Product manager in Marketing, we studied the Brazilian market and trends ,we built a breeding platform in Brazil from scratch which gave us the boost for high level of Xct-resistant plant without compromising all other quality traits.

This success story of Giga is a remarkable example of great cooperation between R&D and Marketing”, Netta goes on to say: “We walked it hand in hand, with top synchronization that greatly contributed to the success of the project”. On top of everything, we have succeeded in creating excellent genetic material for other markets as well.

“Tell us something about you that most people don’t know”

I like to cook but I don’t like fresh tomatoes- I prefer cucumbers. Also, I recently got my kibbutz’s “annual entrepreneur for the community” award for the farm work I do at my home village/

This short glimpse into Netta’s life and daily work truly showcase that breeding does run in one’s DNA.

Grondbewerking en zaaien op het land

Tillage and sowing onions, what about it?

Sowing onions is a precise job because they are fine seeds and onions should not be sown too deep. We recommend 1.5 to 2.5 cm deep sowing in firm moist soil. Before sowing, you first have to till the soil, of course.


On sand, that is ploughing, digging and in some cases non-tilling, in all cases make sure the seedbed is level. For each type of tillage, make sure the soil does not dry out too deeply. We are dealing with drying weather that can easily cause the top layer of ploughed soil to dry out too much. After ploughing or digging, it is very important that the soil lies “closed”. I.e. if one ploughs the soil, immediately prepare the seed bed so that only the top layer dries out but the seed bed remains sufficiently moist. If one ploughs with a front packer, do so in combination with a “trailing roller” (a cross roller, or a Cambridger roller etc). This way, the soil is also “closed” and the moisture remains at the top. This also applies to aforementioned tillages. Till the soil shortly before sowing. When you start sowing, check at what depth the soil is moist and adjust the sowing depth accordingly. When sowing, check regularly whether the seeds are well pressed into the moist soil. Repeat this several times.

Plant numbers

Depending on the bed width and the number of rows, the seed is distributed. Regardless of the sowing system, the most ideal plant number is between 80-90 pl./m2. Plant number generally means a good yield, especially when varieties are used that have a relatively high specific weight, which means they are already heavy in themselves. The number of plants per linear metre is shown on the right, depending on the width of the bed and the number of rows per bed.

Thousand-grain weight

The thousand grain weight of onion seed is always stated on the bags and can vary quite a bit. The risk is that too much or too little seed is sown, which can cause an irregular crop position. When the seed drill is adjusted to a thousand grain weight of 4.2 grams and a following variety has a thousand grain weight of, for example, 3.6 grams, this can cause double seeds on the sowing discs if the suction pressure of the seeder is not adjusted accordingly, and therefore an irregularity in the position of the crop. So check this carefully! Want to know more? Then read this article on the thousand-grain weight.

Mineral administration

What the plant needs in terms of minerals to achieve its kilos, but also to continue to meet the right quality requirements is very important. When which mineral is needed and at which growth stage the plant has the greatest need for the elements is crucial for the quality and final yield. Talk to your fertiliser supplier/business consultant and ask what would be wise for each type of soil and variety. For example, if you grow onions on light sandy soil, this requires a different strategy in terms of mineral application than if you have onions on clay soil of 40% silt.
