Abstract
Irrigation water management in horticultural crops requires timely and accurate determination of crop water status for making irrigation scheduling decisions.
There is potential to improve water use efficiency through smart irrigation systems, especially with the advent of wireless communication technologies, monitoring systems, and advanced control strategies for optimal irrigation scheduling.
Asparagus (Asparagus officinalis L.), due to their deep and well-developed root system, are relatively resistant to the water deficits in the soil.
The aim of the present study was the most efficient agronomic design for water application to asparagus.
The effect of surface drip irrigation was studied on the Grande green asparagus cultivar.
The field experiment was carried out in the third year of the cultivation (2019) at Alcalá del Río near Seville on silty loam soil.
Eight experimental treatments were established consisting of the number of dripper tubes per crop line(0, 0.5, 1 and 2) and irrigation frequency (daily and twice a week). In all treatments, the amount of water applied was the same (cumulative weekly evapotranspiration) except in rainfed.
Drought stress played an important role in limiting fern growth.
Asparagus plants grown on the silty loam soil positively respond to the irrigation treatments.
A lower irrigation frequency and larger irrigated area increased the yield of asparagus.
