- Abstract
Increasing the development and deepening of the root system in coffee crops ensures higher water and nutrient uptakes as a result of improved soil utilization, ultimately leading to greater crop yields and longevity. The aim of this study was to evaluate the effect of irrigation levels on the root system of drip-irrigated coffee plants in western Bahia State (BA), Brazil. The experiment was carried out on Café do Rio Branco farm, located in Barreiras - BA, using adult plants (approximately 3.5 years old) of coffee variety Catuaí Vermelho I AC 144. The experiment was set up as a randomized block design with three treatments corresponding to the irrigation depths of 75, 100 and 150% as determined using Irriplus software. After the fourth harvest, the coffee root system was assessed to determine root length density (RLD) and root weight density (RWD) in different sampled layers. A greater concentration of roots (RLD and RWD) was observed in the surface layer (0-20 cm) and under the lateral line (at 30 and 70 cm from the orthotropic branch). The irrigation depth of 75% provided the highest concentration of roots (RLD and RWD) in the 0-10 cm layer.
