Water management and vegetative cycle

Asparagus (Asparagus officinalis) is a crop with good drought tolerance; however, if drought occurs during the harvest stage, the quality of the shoots is compromised, with a decrease in thickness and turgidity.

To achieve maximum yield, it is best to maintain the soil at field capacity*, ensuring a constant supply of water, adequate availability of nutrients, and avoiding the accumulation of salts above tolerance levels, especially in arid areas.

The vegetative period of asparagus varies depending on the type of planting: 12 months for direct planting and around 9 months for seedling planting.

Once harvesting is complete, the plant begins to develop stems and leaves (cladodes) in order to stimulate photosynthesis until it reaches its maximum growth.

The products of photosynthesis are translocated to the rhizomes and roots, where they are stored as reserves. These reserves enable the formation of new buds, which will give rise to the shoots of the following season, thus ensuring the continuity and productivity of the crop.
