“…This is well described by Potop (2014) who reported a low yield when drought/dryness conditions prevailed in May through August and higher yields under normal wet conditions and by Kučera and Krofta (2009) that reported that the strongest influence on the alpha-acid content was exerted by air temperatures in July and that rainfall had significant effects during the period from May to July. However, few studies have focused an in depth determination of hop water requirements (Bárek et al, 2009;Krofta et al, 2013) and there are no studies providing for an in-depth analysis of evapotranspiration or the water balance. Urban et al (2012) applied the sap flow technique and BREB with the hop cv.…”

This study was conducted during three seasons (2012-2014) in an experimental hop yard at Mabegondo, Galicia, NW Spain. The research aimed at calibrating and validating the soil water balance model SIMD-ualKc for Humulus lupulus L. cv. 'Nugget'. The model computes the soil water balance using the dual K c approach, thus partitioning crop evapotranspiration (ET c) into crop transpiration, ground cover transpiration and soil evaporation. Calibration and validation were performed using TDR soil water content measurements, which produced small root mean square errors (RMSE) ranging from 0.012 to 0.015 cm 3 cm −3. The initial, mid-season and end-season basal crop coefficients (K cb) that allow computing hop transpiration were respectively 0.16, 0.97 and 0.83. The single K c for the same crop growth stages, which refers to transpiration and soil evaporation together, were respectively 0.69, 1.02 and 0.85. SIMDualKc provided to estimate water use by the hop yard and the components of the soil water balance, particularly hop transpiration (T Hop), ground covered transpiration (T cover) and soil evaporation (E s). T Hop represented 92% of actual evapotranspiration (ET c act) during the mid-season, and E s averaged 69% of ET c act during the initial stage. It was observed that T cover was strongly influenced by soil and ground cover management. The impacts of water use and T Hop on hop yield quantity and quality were assessed. A linear regression between hop cone yield and T Hop has been found, with a high coefficient of determination r 2 = 0.92, while the linear regressions of T Hop with alpha and beta-acids had regression coefficients not significantly different from zero. These results denote appropriate irrigation management with absence of stresses that could affect yields or the concentration of bitter acids.

“…Geographic information systems (GIS) are not limited to the field of geography per se [1], but have found broad application in agriculture [2][3][4][5], forestry [6,7], pedology [8], ecology [9], environmental studies [10][11][12][13], botany, biology, landscape planning [14], land consolidation projects [15] and nature conservation. The interconnection of GIS with other diverse scientific disciplines is necessary in the development of methodological procedures and terminology for working with spatial soil data [16].…”

The goal of this study was the spatial processing and showcasing selected soil properties (available water capacity, total organic carbon content and the content of clay fraction <0.001 mm) in the Nitra River Basin (Slovakia) via the usage and the subsequent evaluation of the quality of applied interpolation methods (Spline, inverse distance weighting (IDW), Topo to Raster). The results showed the possibilities of “conversion” of point information obtained by field research as well as research in the laboratory into a spatial expression, thus providing at least relevant estimation of the soil properties even in localities not directly covered by soil sampling. Based on the evaluation and mutual comparison of the accuracy of the used interpolation methods (by using the so-called cross-validation and trust criteria), the most favorable results were achieved by the Spline method in the GRASS GIS environment, and in the ArcGIS environment. When comparing the measured and estimated values of given soil properties at control points, the interpolated values classified as very accurate up to accurate prevailed in the verification dataset. Qualitatively less favorable (but still acceptable) were the results obtained with Topo to Raster (ArcGIS) interpolation method. On the contrary, the Spline method in the ArcGIS environment turned out to be the least accurate. We assume that this is most likely not only a consequence of insufficient density of points (resources), but also an inappropriate implementation of the method into the ArcGIS environment.

“…The contextual literature on irrigation has been informing on the particularities of the irrigation sector in the Danube countries, particularly in the Lower Danube where irrigation has a long tradition. While the syntheses on irrigation remain valuable sources of information in terms of past developments of the agricultural infrastructure, crop suitability and environmental impacts in irrigated areas (Grumeza and Kleps, 2005;Bárek et al, 2009), the local case-studies provide details on the conditions and parameters of various agricultural regions for optimum irrigation schemes, such as timing, watering norms, water use efficiency in irrigated vs. rain-fed conditions, etc. The results of numerous empirical studies and field experiment applications concerning irrigation water use for most common crops under various local conditions in the Danube Basin are found in the annual series and communications published in the journals and bulletins of specialized institutions, such as the National Research Institute of Agriculture in Romania, the Agricultural Faculties (e.g.…”

In this paper we assess the irrigation water use in the Danube Basin, highlight its complexity, identify future challenges and show the relevance for a basin-wide integrative irrigation management plan as part of a more holistic and coherent resource policy. In this sense, we base our integrative regional assessments of the water-food-energy nexus on insights from an extensive review and scientific synthesis of the Danube Basin and region, experimental field studies on irrigation and agricultural water consumption, current irrigation related policies and strategies in most of the Danube countries, and regulatory frameworks on resources at European Union level. We show that a basin-wide integrative approach to water use calls for the evaluation of resource use trade-offs, resonates with the need for transdisciplinary research in addressing nexus challenges and supports integrative resource management policies within which irrigation water use represents an inherent part. In this respect, we propose a transdisciplinary research framework on sustainable irrigation water use in the Danube Basin. The findings were summarized into four interconnected problem areas in the Danube Basin, which directly or indirectly relate to irrigation strategies and resource policies: prospective water scarcity and Danube water connectedness, agricultural droughts, present and future level of potential yields, and science based proactive decision-making.
