Seed shattering is a key constraint to improvement of seed yield in perennial ryegrass and, as result, retention an essential trait for breeding this valuable crop. It unclear whether sources are available plant breeders. Field studies were conducted near Corvallis, OR 2 yr (2017–2018 and 2018–2019) identify genetic variation ascertain there was phenotypic traits that may contribute loss due sh...

Sufficient nitrogen (N) supply is decisive to achieve high grass seed yields while overfertilization will lead negative environmental impact. From the literature, estimation of N rates taking into account crop’s status and its yield potential, seems promising for attaining averting adverse impacts. This study aimed at an evaluation remote sensing predict final yield, traits crop usability nutri...

Context Tagasaste (Cytisus proliferus), a fast-growing leguminous tree, has potential to supplement pasture production in steep-hill country and increase resilience.Aims In the companion paper, we quantified tagasaste characteristics. Here, determine effect of proximity 10-year-old trees on productivity eight species including grasses (perennial ryegrass, Lolium perenne; cocksfoot, Dactylis glo...

In this study, the effect of two allelochemicals, benzoxazolin-2(3H)-one (BOA) and cinnamic acid (CA), on different physiological and morphological characteristics of 1-month-old C(3) plant species (Dactylis glomerata, Lolium perenne, and Rumex acetosa) was analysed. BOA inhibited the shoot length of D. glomerata, L. perenne, and R. acetosa by 49%, 19%, and 19% of the control. The root length o...
