Leaf temperature of maize and Crop Water Stress Index with variable irrigation and nitrogen supply
Springer Science and Business Media LLC - Tập 35 - Trang 549-560 - 2017
David A. Carroll, Neil C. Hansen, Bryan G. Hopkins, Kendall C. DeJonge
Crop canopy temperature and Crop Water Stress Index (CWSI) are used for assessing plant water status and irrigation scheduling, but understanding management interactions is necessary. This study evaluated whether nutrient deficiencies would confound interpretation of plant water status from leaf temperature. Leaf temperature and CWSI in maize (Zea mays L.) were evaluated with different irrigation ...... hiện toàn bộ
The effects of applied water at various fractions of measured evapotranspiration on water relations and vegetative growth of Thompson Seedless grapevines
Springer Science and Business Media LLC - Tập 28 - Trang 221-232 - 2009
L. E. Williams, D. W. Grimes, C. J. Phene
Vegetative growth and water relations of Thompson Seedless grapevines in response to applied water amounts at various fractions of measured grapevine ETc were quantified. Treatments ranged from no applied water up to 1.4 times the water used by vines growing in a weighing lysimeter. All treatments were irrigated at the same frequency as the vines in the lysimeter (whenever they used 2 mm of water)...... hiện toàn bộ
Impact of research on water use for irrigation in Israel
Springer Science and Business Media LLC - Tập 25 - Trang 443-445 - 2006
Marcel Fuchs
The decrease of annual irrigation application rate observed since 1950 was reversed in 1988 as a result of a sudden increase of the amount of treated effluents used for irrigation. Intensification of research on irrigation with effluents and marginal water starting in 1994 resulted four years later in the renewal of the decrease of irrigation application rate.
Canopy-air temperature differentials, water use and yield of chickpea in a semi-arid environment
Springer Science and Business Media LLC - Tập 7 - Trang 149-158 - 1986
M. V. K. Sivakumar
Stress degree days (SDD) and canopy-air temperature differential summation procedures were used to quantify the response of crops of chickpea (Cicer arietinum L.) to soil water availability and atmospheric demand over a four year period on a deep and medium-deep Vertisol in India using different irrigation treatments and planting dates. Canopy temperatures measured between 13.00–14.00 h provided a...... hiện toàn bộ
Assessing and mapping vineyard water status using a ground mobile thermal imaging platform
Springer Science and Business Media LLC - Tập 39 - Trang 457-468 - 2021
Salvador Gutiérrez, Juan Fernández-Novales, María-Paz Diago, Rubén Iñiguez, Javier Tardaguila
Water status directly affects yield and crop quality in grapevines. Precision viticulture demands the application of new available technologies and methodologies for accurate irrigation management in vineyards. The objective of this work was the development of an on-the-go thermal imaging application for the assessment and mapping of vineyard water status, building a dataset from a commercial Temp...... hiện toàn bộ
Effects of different irrigation regimes applied during the final stage of rapid growth on an early maturing peach cultivar
Springer Science and Business Media LLC - Tập 27 - Trang 297-306 - 2009
Vincent Mercier, Claude Bussi, Françoise Lescourret, Michel Génard
Different irrigation regimes were performed on container-grown early-season peach trees (cv. Alexandra) during stage III of fruit growth. In the first experiment, three water treatments were applied: T1, control irrigation; T2, light water restriction; T3, high water restriction. In the second experiment, T4, a light water restriction, was compared to T5, the same total amount of water as T4 but w...... hiện toàn bộ
Soil-based automated irrigation for a nectarine orchard in two water availability scenarios
Springer Science and Business Media LLC - Tập 39 - Trang 421-439 - 2021
María R. Conesa, Wenceslao Conejero, Juan Vera, M. Carmen Ruiz-Sánchez
This work studies the feasibility of using automated drip irrigation based on the volumetric soil water content measured with capacitance probes in early maturing nectarine trees (Prunus persica L. Batsch, cv. ‘Flariba’) grown in a clay–loam soil in Mediterranean conditions. An automated irrigation treatment (AUTO), based on the management allowed depletion (MAD) concept (with a feed-back control ...... hiện toàn bộ
Comparative analysis of micro-physical characteristics of sprayed droplets using various measurement technologies
Springer Science and Business Media LLC - - 2024
Rui Zhang, Yichuan Liu, Delan Zhu, Pute Wu, Wenbo Xia, Changjuan Zheng, Xiaomin Zhang
The study of the micro-physical characteristics of spray droplets provides crucial insights into the impact of sprinkler water on soil erosion, leaf impact, and the microclimate of agricultural environments. However, the variability in measurement outcomes across different technologies due to their distinct measurement principles is a significant challenge. This research aims to evaluate and compa...... hiện toàn bộ
Root system parameters determining water uptake of field crops
Springer Science and Business Media LLC - - 1991
W. Ehlers, A. P. Hamblin, D. Tennant, R. R. van der Ploeg
The distribution of a crop rooting system can be defined by root length density (RD), root length (RL) per soil layer of depth Δz, sum of root length (SRL) in the soil profile (total root length) or rooting depth (z r . The combined influence of these root system parameters on water uptake is not well understood. In the present study, field data are evaluated and...... hiện toàn bộ
The growth and nitrogen economy of rice under sprinkler and flood irrigation in South East Australia
Springer Science and Business Media LLC - Tập 10 - Trang 183-199 - 1989
W. A. Muirhead, J. Blackwell, E. Humphreys, R. J. G. White
The agronomic implications of growing rice under sprinkler irrigation on a duplex soil in inland south east Australia were examined by comparing 3 sprinkler irrigation regimes applied once, twice and three times a week (S1W, S2W and S3W) with continuous flood irrigation (CF). Each sprinkler irrigation treatment was managed to replace evaporative loss since the previous irrigation. Each irrigation ...... hiện toàn bộ
