A simulation study on the interactive effects of radiation and plant density on growth of cut chrysanthemum [PDF]

open access: yes, 2002
In the present study, we used a photosynthesis-driven crop growth model to determine acceptable plant densities for cut chrysanthemum throughout the year at different intensities of supplementary light.

Reference crop evapotranspiration database in Spain (1961–2014) [PDF]

open access: yesEarth System Science Data, 2019
Abstract. Obtaining climate grids describing distinct variables is important for developing better climate studies. These grids are also useful products for other researchers and end users. The atmospheric evaporative demand (AED) may be measured in terms of the reference evapotranspiration (ETo), a key variable for understanding water and energy ...

GBS-SNP-CROP: a reference-optional pipeline for SNP discovery and plant germplasm characterization using variable length, paired-end genotyping-by-sequencing data [PDF]

open access: yes, 2016
Background: With its simple library preparation and robust approach to genome reduction, genotyping-by-sequencing (GBS) is a flexible and cost-effective strategy for SNP discovery and genotyping, provided an appropriate reference genome is available. For

Reference crop evapotranspiration over Greece

open access: yesAgricultural Water Management, 1991
Abstract Monthly evapotranspiration (ET) estimates for 31 locations in Greece are calculated by the Penman, Priestley-Taylor and Thornthwaite methods. The analysis of 27 years of routine meteorological data indicates that annual amounts of ET obtained by Priestley-Taylor or Thornthwaite methods do not generally agree very well with Penman ET (ETPEN ...

Representing uncertainty in continental-scale gridded precipitation fields for agrometeorological modeling [PDF]

open access: yes, 2008
This work proposes a relatively simple methodology for creating ensembles of precipitation inputs that are consistent with the spatial and temporal scale necessary for regional crop modeling.

Estimation of Reference Crop Evapotranspiration in Northwest China [PDF]

open access: yesEarth Sciences, 2020
Based on the daily meteorological data from 1956 to 2011 in Northwest (NW) China and the Penman-Monteith (PM) equation, the regional reference crop evapotranspiration (ET0) is estimated. The ET0 variations in time series and spatial distributions are analyzed.

Use of supplementary lighting top screens and effects on greenhouse climate and return on investment [PDF]

open access: yes, 2008
Discomfort caused by light pollution from greenhouses that apply supplementary lighting is an issue in Dutch society nowadays. At this moment Dutch legislation requires an opaque screen that reduces light transmission of the greenhouse wall by 95%.
