Grain yield increased from 2.14 to 2.34 Mg/fed by percentage 9.32% by using automated irrigation compared with traditional irrigation. A water saving of 30 and 20% was achieved in the T-1 and T-2 treatments, respectively. To model LUCC a Cellular automata-Markov chain approach was applied. Unlike AE, RE, RDE, and TDE parameters are well-correlated with relative yield. The experiments were arranged in strip-plot design with three replicates. A postharvest RDI treatment (RDI-P) was irrigated at 0.35 of control after harvest. Sci. The emitters, which are attached to the laterals, distribute water for irrigation… In recent years, there has been an increase in the number of studies analyzing agricultural irrigation from the perspective of sustainability with a focus on its environmental, economic, and social impacts. Irrigated agriculture plays a fundamental role as a supplier of food and raw materials. ... 11 Many studies about autonomous robot for agricultural applications can be found in scientific literature. An additional treatment, denominated 50%-Year, was irrigated at 50 % ETlys during the whole year. rch Centers in Priority Areas (FONDAP CRHIAM in spanish) of National Commission for Scientific & Technological Research (CONICYT); 135:401-412. abiotic stress for irrigation management, and yield components. Cabernet Sauvignon. Eng. Previous experimental studies carried out under certain climatic and soil conditions showed that risk of ground water pollution could be reduced by 20-30% if water and fertilizer are applied separately (by Alternative Furrow Irrigation-AFI). For testing hypotheses, structural equation model and partial least squares that focus on reagent variance were used. – El tercer objetivo es crear redes con instituciones de investigación, nacionales e internacionales y con el sector público y privado del país para beneficiarse de la investigación cooperativa y de la transferencia de tecnología. surface irrigation was lower than for drip irrigation. On the other side, the M2 received the lowest with sub-surface drip irrigation. Moreover it can be seen that when three different typical soil of the area were considered, the EDT was, 91.85%, 91.47% and 90.30% respectively, according with different water storage capacity of each soil. The season was divided into three preharvest periods: leafout to full shell expansion (Stage 1), full shell expansion to the onset of rapid kernel growth (Stage 2), and rapid kernel growth to harvest (Stage 3). Treatments consisted of a control, irrigated during the whole year at 115% of crop evapotranspiration measured in a weighing lysimeter (ETlys) and RDI treatments, where irrigation was reduced at different levels and duration after 'June drop'. This project is the complete design of the … In contrast, an increase in furrow length increases AE while an increase in inflow discharge and cutoff time reduces it. The objective of this paper is to optimize the modeling approach in order to simulate acceptably precisely water and nitrogen transfer under different water/fertilization practices. The UCC and the UCMQ reflects prop- erly the irrigation design, while the EDT reflects irrigation design, management and maintenance. Micro-jet irrigation increased system maintenance and resulted in higher herbicide use to control vegetation on the orchard floor. All rights reserved. m. The study concluded that sprinkler irrigation was almost one and half fold economical than the furrowirrigation. This paper describes a methodology engaging stakeholders (from the land use planning, agriculture, and forest sectors) in the building and assessment of future LUCC scenarios. Five different irrigation strategies, full irrigation, rain fed, and three deficit irrigation treatments were compared from 1996 to 1999, in Cordoba, southern Spain, to characterize the response of a mature olive (Olea europaea L. 'Picual') orchard to irrigation.
