Other claims from this paper (5)

Intervention effect Yield and N content were greatest at pH 6.8 in pots sown with only Lolium perenne.
Intervention effect Yield and N content were greatest at soil pH 6.1 in pots sown with Trifolium repens and Lolium perenne.
Observation Trifolium repens established only at soil pH between 4·3 and 6·1.
Association Sward yield was slightly reduced as soil pH increased from 3·8 to 4·3.
Mechanism The decrease in total N at low pH was attributed to increased N immobilization in the soil microbial biomass.

Title

Biostimulating effect of l‐tryptophan on the yield and chemical and microbiological quality of perennial ryegrass (Lolium perenne) herbage and silage for ruminant

Sebastian W Przemieniecki; Cezary Purwin; Jędrzej Mastalerz; et al. Journal of the Science of Food and Agriculture 2020. doi:10.1002/jsfa.10999

Other claims from this paper (10)

Intervention effect The 5 kg ha −1 dose increased herbage yield by 15% versus C.
Intervention effect The 5 kg ha −1 yield approximated the C+ yield.
Intervention effect Tr5 increased water‐soluble carbohydrate content to 165 g kg −1 DM.
Intervention effect The treatment improved fermentation with lower pH of 4.59.
Intervention effect The treatment raised fermentation acids including lactic acid to 94.7 g kg −1 DM.
Intervention effect A high l‐TRP dose reduced Clostridium loads.
Intervention effect A high l‐TRP dose reduced fungal loads.
Intervention effect A high l‐TRP dose increased Bacillus counts.
Intervention effect Tr05 reduced N‐NH 3 content versus C+.
Recommendation The authors identified 5 kg ha −1 as the most effective dose for yield and fermentation.
