Abstract
This study aimed to evaluate the dry matter production and nutrient accumulation of coriander (Coriandrum sativum L.) under pulse and continuous fertigation depths. The experiment was conducted in randomized blocks in 2 x 5 factorial arrangement, with three replicates. Treatments consisted of two types of fertigation application (pulse and continuous) and five fertigation depths (40, 60, 80, 100 and 120% of crop evapotranspiration – ETc). Highest accumulations of dry matter, N, P, K, Fe, Mn, Cu and Zn were obtained with pulse fertigation. Pulse fertigation combined with depths lower than 100% ETc led to highest accumulations of K, Mn, Cu and Zn. The accumulation of nutrients decreased in the following order: K > N > Ca > P > Mg > S > Fe > Mn > Zn > Cu.
