Tribulus mollis

The optimal planting time is mid-spring, as the seeds require high temperatures to germinate successfully. Light, sandy soils with neutral to slightly alkaline pH are preferred for commercial cultivation.

Seeds should be sown at a depth of 1–2 centimeters, ensuring sufficient spacing between plants to accommodate their spreading, prostrate growth habit.

Maintenance of stable soil moisture during the first week of germination is crucial. Once the seedlings develop two true leaves, thinning is recommended to ensure optimal spacing of 30–40 centimeters.

Commercial plantations often employ row sowing patterns to facilitate mechanized weeding and field maintenance throughout the growing season.

This crop is a classic xerophyte, well-adapted to arid environments and intense sunlight. It thrives in regions with hot, dry summers and limited precipitation.

Proper soil drainage is essential for this plant; waterlogging must be strictly avoided, as it significantly increases the risk of root rot and plant death.

Tribulus mollis prefers loose, well-aerated sandy substrates with low organic matter content. It demonstrates high tolerance for saline conditions, making it suitable for developing marginal lands.

The temperature optimum for development ranges from +25 to +35 degrees Celsius. Growth slows significantly if temperatures drop below +10 degrees Celsius.

The plant requires minimal fertilization but responds well to minor micronutrient supplementation when grown on extremely nutrient-poor, sandy soils.

The yield of green biomass depends on sunlight availability and effective weed management. Under ideal conditions, a yield of 5–8 tons per hectare can be achieved.

Harvesting for medicinal raw material should take place during the peak flowering phase, as this is when the concentration of active chemical components is highest.

Two harvest cycles per season are possible with proper field management and occasional weeding. The second cut is generally lighter but maximizes the economic utility of the land.

Drying the material in shaded, well-ventilated areas is necessary to preserve the essential phytochemical properties. Direct sun exposure can degrade the quality of the raw material.

Dry matter yield usually accounts for 20–25 percent of the fresh weight. Proper drying protocols are key to ensuring the long-term stability and quality of the harvested product.

Root rot caused by fungal pathogens is the primary threat, typically arising from poor water management or excessive humidity. Maintaining soil aeration is the best preventive measure.

Pests such as aphids and spider mites can damage foliage and stems, especially during periods of extreme heat and drought when plants are under physiological stress.

Effective prevention involves rigorous crop rotation and weed control, as weeds can act as reservoirs for common agricultural pests and diseases.

The use of biological control agents is encouraged, as synthetic insecticides may leave residues that interfere with the intended medicinal use of the crop.

• Monitoring fields for early signs of leaf discoloration
• Ensuring adequate spacing to prevent air stagnation
• Proper disposal of plant residues after harvest
• Routine check-ups for pest colonization during drought
• Selective use of biopesticides only when necessary

Harvesting is typically mechanized using mowers set to an appropriate height to avoid soil contamination. This ensures high purity of the gathered biomass.

Work should be carried out in dry conditions, as moisture from dew or rain can lead to rapid deterioration and molding of the raw material during initial storage.

Freshly cut material should be transported quickly to drying facilities to prevent heat buildup and self-heating of the biomass, which significantly lowers quality.

Post-harvest cleanup of the field is mandatory to minimize the pathogen load for the subsequent season. Removing all debris helps maintain a healthy rotation environment.

Storage should occur in a cool, dry place with continuous air circulation. When kept under optimal conditions, the dried raw material can remain viable for several years.
