Water-conservation traits to increase crop yields in water-deficit environments : case studies [Monograph]
Sinclair, Thomas \ 2017
Agricultural conservation - Crops Drought tolerance - Crops Effect of drought on

Abstract:
This volume explores specific approaches that have shown to result in crop yield increases. Research on the physiological understanding of these methods has led to the development of practical applications of plant breeding approaches to genetically improve crops to achieve higher yields. Authoritative entries from crop scientists shed new light on two water-conservation traits: one that is based on an initiation of the decrease in transpiration earlier in the soil drying cycle, and the second that is based on a sensitivity of transpiration rate under high atmospheric vapor pressure deficit that results in partial stomatal closure. Both these approaches involve partial stomatal closure under well-defined situations to decrease the rate of soil water loss. Readers will be able to analyze the circumstances under which a benefit is achieved as a result of the water-limitation trait; and key discussion points in the case studies presented will help answer questions such as what species, which environments, how often will yield be benefited for various crop species? Contributions also review the genetic variation for these two traits within each crop species and the physiological basis for the expression of these traits.

How peasants read their farm \ Farming matters : small-scale agriculture for a sustainable society [Article]
Ploeg, J.D. van der \ 2016
farming systems - farm planning - sustainability - alternative farming - organic farming

Abstract:
Whereas yield increases are considered central in modernised agriculture, they can be seen as just one element of impact in peasant farming. In assessing their farms, peasants depart from the specificities of their farm, the ecosystem in which it is embedded, the society and the markets in which they operate, and the possibilities and limitations entailed in their own families. This holds even truer when peasants work with agroecology.

Abstract:
Bemesting is een van de sleutelfactoren voor een succesvolle aardbeienteelt. Naast een kwantitatief en kwalitatief goede productie, zijn ook het in stand houden van de bodemvruchtbaarheid en rekening houden met factoren die impact hebben op het milieu belangrijke aspecten bij het plannen van de bemesting van de aardbeien in de vollegrond.

Maximising the yield of biomass from residues of agricultural crops and biomass from forestry : final report [Monograph]

Abstract:
There is a huge potential for yield increase of agricultural crop residues and biomass from forestry in the European Union, Ukraine, Russia and Belarus. A stepwise approach was used to identify the realistic potential in these regions, starting with an estimate of the theoretical potential based on crop- and forest-type specific best practices for yield increase, which is then narrowed down to a technical-sustainable potential. Ecofys developed and assessed best practice strategies for residue yield increase with regard to their feasibility of application in the EU, Ukraine, Russia and Belarus.

Yielding a fruitful harvest : advanced methods and analysis of regional potentials for sustainable biomass value chains interlinked with environmental and land use impacts of agricultural intensification [PhD thesis]

biomass production - yield increases - intensive cropping - land use - environmental impact - value chain analysis - sustainability - biobased economy

Abstract:
This thesis examined the regional potentials, the environmental impacts and economic performance of different pathways for agricultural intensification, biomass production and biomass use. To this end, the following research questions were formulated: 1. What are regional possibilities for agricultural intensification and what are their impacts on the demand for agricultural land and biomass potentials? 2. What is the effect of different agricultural intensification pathways and biomass production on GHG emissions and the environment? 3. Which biomass value chains are preferred today as well as in the future with regard to their economic performance and GHG balance?

Abstract:
Het Landbouwcentrum Granen (LCG) legde dit jaar op 9 plaatsen rassenproeven voor wintertarwe aan. Hoewel een moment noodrijpheid werd gevreesd wegens de droogte, kon de regen bijna overal voor een zeer behoorlijke opbrengst zorgen. De gemiddelde opbrengst van de getuigenrassen was op de meeste plaatsen hoger dan ooit.

Abstract:
The ILUC Prevention project aimed at providing insights into how ILUC (risks) can be mitigated by taking a sustainable approach to all crop production for all purposes, how this can be quantified and how ILUC (mitigation) may be regulated. Key ILUC prevention measures (e.g. above-baseline yield increases and cultivation of currently under-utilized land) were quantified for four case studies by assessing how much additional biofuel feedstock can be produced with low risk of causing ILUC. Key results from case studies: Large biofuel potentials with low risk of causing ILUC exist in all case studies.

Abstract:
Op een proefveld in Bree, dat door de Bodemkundige Dienst van België (BDB) werd opgevolgd in samenwerking met de Vlaamse Landmaatschappij (VLM), bleek dat het beregenen van aardappelen in 2013 tot meeropbrengsten leidde. Beredeneerde irrigatie leidt tot een efficiëntere stikstofopname door het gewas, met een lagere stikstofrest in de bodem tot gevolg.

Abstract:
De snel toenemende vraag naar palmolie leidt tot ongewenste neveneffecten: vernietiging van oerwouden en sociale misstanden zijn daarvan bekende voorbeelden. Minder bekend is dat een flink deel van de palmolieproductie in handen is van kleine boeren. Het stimuleren van deze kleinschalige productiewijze kan de negatieve impact van de palmolie aanzienlijk verminderen.

Abstract:
In het buitenland is het kruislings poten allang niet meer bijzonder.

Opbrengstverhoging snij-amaryllis (Hippeastrum) : teelt voor kerstbloei in 3-jarig gewas van 2010 t/m 2012 [Monograph]

Abstract:
Om de rentabiliteit van snij-amaryllis ( Hippeastrum ) te verbeteren is onderzoek uitgevoerd naar productieverhoging voor de kerstbloei. In een kas van 600 m2 is een teeltstrategie toegepast gericht op optimalisatie van de fotosynthese met verneveling en een diffuus schermdoek. De productie was vergelijkbaar tot iets hoger dan gemiddeld in de praktijk, maar lager dan verwacht door een tragere doorgroei tot bloeibare knop en toename van achterblijvende bollen. Geoogste bloemstelen bleken 10 tot 22 maanden voor de oogst aangelegd. De oudste knoppen zijn het meest gevoelig voor knopverdroging. Verhoging van de bodemtemperatuur van 22 naar 24o C vanaf het vroege voorjaar tot de start van de koeling gaf meer Fusarium en geen productieverbetering ten opzichte van continu 22o C. Op perliet was de productie iets hoger dan op kleikorrels. De cultivar Mont Blanc gaf minder bloemstelen, maar een hoger steelgewicht dan Red Lion. Omdat productieverhoging van een enkele bol lastig is, zal productieverhoging vooral moeten komen uit een vermindering van achterblijvers en gezond houden van de bollen.
