Introduction
My research focuses on sustainable cropping systems, climate-resilient crops, and open-field horticulture. I am looking at the environmental stress-sustainability of these crops. Currently, I am working on implementing and evaluating smart plant protection technologies.

Quinoa is a strategic crop due to its high N content and its adaptability to adverse conditions, where most of the soils are deficient of nitrogen (N). The central question in this review was the following: How can quinoa yield low levels of nitrogen in the soils of Altiplano? This question was unraveled based on different factors: (1) fertilizatio...

Sandy soils are considered marginal, owing to their low soil fertility, due to their low soil organic carbon and clay contents. The marginality is particularly pronounced when sandy soils exist in hot and arid environments, such as in the UAE and other GCC countries. Three field trials were undertaken in three agricultural seasons, i.e., 2014, 2015...

Small farmers worldwide are the custodians of agro-biodiversity belonging to both the plant and animal kingdoms. Grains and vegetables are the essentials needed to sustain our food systems. Goosefoots, i.e., Chenopodium species like kañawa (Ch. pallidicaule) and Quinoa (Ch. quinoa), are prominent examples of domestication by small farmers during an...

Quinoa (Chenopodium quinoa, Willd.) is a high-quality protein grain originating in the Andean region. Once a staple of the Incas, from being unknown in the rest of the world, this grain has recently become a global commodity. This is largely due to its nutritional qualities and adaptation to a wide range of environments. While the majority of quino...

Salinity is affecting many regions in the world, and common crop plants are not capable of growing under these conditions. First, to introduce new plants to other ecosystems, it is necessary to understand how they perform under salinity conditions. Some plants can grow under high salinity conditions as halophytes. Quinoa, an Andean native crop, is...

In the last 30 years, quinoa started to be tested and produced in more than 100 countries outside the Andes, its region of origin. Nowadays, quinoa is found in more than 120 countries around the globe. During this time, biotechnology has become an important tool for different areas of research in quinoa, especially with the use of genetic markers....

With the ever-increasing world population, an extra 1.5 billion mouths need to be fed by 2050 with continuously dwindling arable land. Hence, it is imperative that extra food come from the marginal lands that are expected to be unsuitable for growing major staple crops under the adverse climate change scenario. Crop diversity provides right alterna...

Arable lands are dwindling due to rapid urbanization or turning into marginal/unsuitable lands due to non-sustainable exploitation of natural resources. By 2050, we will have extra 1.5 billion mouth to feed. Not only to feed the extra mouths but also give them nutrient rich food, the burden will fall on Marginal Lands to address the problem. At ICBA, Dubai, we are working to develop strategies that will allow to grow the nutrient rich food from marginal lands under harsh climate using crop diversity and climate resilient crops like Quinoa etc.
