MEJIA DE TAFUR, María Sara; MARIN PIMENTEL, Gilberto Eduardo  e  MENJIVAR FLORES, Juan Carlos. Physiological response of coriander (Coriandrum sativum L.) to water soil availability. Acta Agron. [online]. 2014, vol.63, n.3, pp.246-252. ISSN 0120-2812.  https://doi.org/10.15446/acag.v63n3.39826.

An experiment was conducted to determine water requirements of coriander Unapal Precoso related to fresh foliage yield and dry matter. Plants were sown in pots with 6 kg of soil and water depths of 140, 160, 200 (witness proposed by Vallejo y Estrada, 2004), 240 and 280 mm were applied. A random complete block design was used with 5 treatments and 4 replications, with 36 plants per experimental unit. Daily evapotranspiration measurements were made. Production of foliage and biomass was evaluated 35 days after sowing. Increased production of foliage was obtained with 200 mm of water depth, value associated with greater efficiency in water use (0.64 grams of dry matter per liter of water applied). The crop Kc was determined: 0.83 at the stage of germination, 1.12 in linear growth stage and 1.40 on the stage of forming flower stems and harvesting.
