Cardinal temperatures and thermal time requirements for germination of annual and perennial temperate pasture species
(The Agronomy Society of New Zealand, 2009)
Cardinal temperatures (base (Tb), optimum (To) and maximum (Tm)) and thermal time (Tt) requirements for germination of 21 temperate annual and perennial grass, legume and weed species were calculated from incubator ...
Two annual legume species and their selection of nodule occupants
With its intensive animal production, New Zealand relies heavily on legume and ryegrass dominated pastures. Legumes in association with their rhizobial symbionts fix nitrogen and provide high quality forage. Little is known ...
Strain diversity of rhizobia occupying lucerne and Caucasian clover nodules in New Zealand high country soil
A poster summarising a study that aims to quantify nodulation and genetic diversity of strains recovered from lucerne and Caucasian clover, grown in soils of low pH and high aluminium.
An explanation of yield differences in three potato cultivars
(American Society of Agronomy, 2016-07)
Under ideal growing conditions, yield is the product of intercepted photosynthetically active radiation (PARi) and its conversion efficiency to dry matter (radiation use efficiency, RUE). For potato (Solanum tuberosum L.) ...
Alfalfa coumestrol content in response to development stage, fungi, aphids, and cultivar
(American Society of Agronomy, 2018-03-29)
Coumestrol produced by alfalfa (Medicago sativa L.) can reduce the ovulation rate of ewes. This study isolated agronomic factors that affect coumestrol levels in alfalfa. Fungal diseases explained most differences in ...
Cardinal temperatures and thermal time requirements for germination of forage brassicas
(Agronomy New Zealand, 2012)
Cardinal temperatures, base (Tb), optimum (Topt) and maximum (Tm), and thermal time (Tt) requirements were defined for germination of nine forage brassica cultivars. Seeds were germinated at nine constant temperatures. ...
