Under this premise, the present research work was developed with the objective of evaluating irrigation methodologies on the agro-productive response of corn (Zea mays) in Bolivar Canton, Manabi; different deficit irrigation methodologies were evaluated: optimized deficit irrigation by stages (ORDI) and partial root drying (PRD), forming the following treatments: T1: control treatment without deficit, T2: ORDI 50 %, T3 ORDI 50 % + PRD 1 week, T4 ORDI 50 % + PRD 2 weeks, T5 ORDI 50 % 1 week, T6: ORDI 50 % 2 weeks; using a completely randomized block design (DBCA), with a total of 24 experimental units; for which variables of agro-productive behavior were evaluated; among the most relevant results, it was obtained that treatments 1 and 2, presented the highest agro-productive yields, reaching an average yield of 8.81 and 7.37 Mg/ha-1 of dry hard corn respectively; In terms of water productivity, T2 and T5 showed the highest productivity with an average value of 38.39 and 36.66 kg/mm, respectively, thus making the most efficient use of water in relation to the other treatments. |
