Impact of defoliation intensity and frequency on N uptake and mobilization in Lolium perenne [PDF]

Journal of Experimental Botany, 2006
The aim of the study was to evaluate the impact of defoliation intensity, defoliation frequency, and interactions with N supply on N uptake, N mobilization from and N allocation to roots, adult leaves, and growing leaves. Plants of Lolium perenne were grown under two contrasted N regimes.

Effects of intensity and frequency of defoliation on a mixture of guinea grass (Panicum maximum cv. Coloniao) and Verano stylo (Stylosanthes hamata cv. Verano) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Plant Science at Massey University [PDF]

, 1985
A study was conducted in a glasshouse to determine the effect of defoliation treatments comprising combinations of two intensities (7.5 cm and 15.0 cm cutting height) and three frequencies (2, 3 and 6 weeks) on production, botanical composition and crude

Tissue flow and biomass production of piatã grass in function of defoliation frequency and nitrogen fertilization

COLLOQUIUM AGRARIAE, 2019
Due to the multifactorial interplay of the morphogenic, morphologic and agronomic characteristics of forage species, it is necessary to find management options that increase the production and utilization of the forage mass of grasses when submitted to different defoliation frequencies and nitrogen application levels The objective of this study was to ...

Structural and Productive Characteristics of Urochloa Cultivars Submitted to Different Defoliation Frequencies in Semiarid Region

Journal of Agricultural Studies, 2019
This study assessed the effect of three cutting intervals (30, 45 and 60 days) on structural and production features of five different cultivars (Urochloa Brizantha: Marandu, Piatã and Xaraés; Urochloa decumbens: Basilisk; Urochloa hybrid: Mulato I). The experiment was carried out in a completely randomized design.

Effect of intensity and frequency of defoliation on growth of ryegrass, tall fescue and phalaris

Proceedings of the New Zealand Grassland Association, 1990
Pasture growth rates of ryegrass, tall fescue and phalaris were compared under combinations of 2 defoliation heights and 3 defoliation frequencies in mowing trials run in spring, summer, autumn and winter over 2 years. Lax defoliation gave on average 15%, 20% and 21% higher pasture growth rates than intense defoliation for ryegrass, tall fescue and ...

Forage productivity and chemical composition of Panicum maximum cv. Mombaça under defoliations intensities and frequencies

Research, Society and Development, 2021
The effects of defoliation frequency (28, 35, 42 and 49 days) and defoliation intensity (30, 40 and 50 cm above the ground) on green dry matter (GDM) yield, and chemical composition of Panicum maximum cv. Mombaça were evaluated under natural field conditions at the Roraima´s savannas.

Structural characteristics of Puerto Rico stargrass (Cynodon nlemfuensis) pastures under different frequencies and severities of defoliation

Tropical Grasslands - Forrajes Tropicales, 2013
An understanding of the effects of frequency and severity of defoliation on the sward structure of pastures is essential for identifying pasture management strategies that are more efficient in forage usage in tropical environments (Da Silva and Nascimento Jr 2007; Euclides et al. 2010).
