This paper presents validation results and some management applications of a Tropical Pasture Simulator. The e ects of di erent environmental conditions, N fertilisation regimes and grazing intensities are analysed, and physiological concepts are used to aid in the inter- pretation of the respons...


Herrero, Mario T.Fawcett, R.H.Dent, J.B.[Modelling the growth and utilisation of kikuyu grass (Pennisetum clandestinum) under grazing. 2. Model validation and analysis of management practices]Modelling the growth and utilisation of kikuyu grass (Pennisetum clandestinum) under grazing. 2. Model validation and analysis of management practices

This paper describes a Tropical Pasture Simulator. This is a simple mechanistic model representing the growth of vegetative tropical pastures under rotational or continuous grazing with responses to N fertiliser, temperature and irradiance that can be used as a tool to study management options fo...


Herrero, Mario T.Fawcett, R.H.Silveira, V.Busqué, J.Bernués, A.Dent, J.B.[Modelling the growth and utilisation of kikuyu grass (Pennisetum clandestinum) under grazing. 1. Model definition and parameterisation]Modelling the growth and utilisation of kikuyu grass (Pennisetum clandestinum) under grazing. 1. Model definition and parameterisation

Appropriate selection of holistic management strategies for livestock farming systems requires: (1) understanding of the behaviour of, and interrelations between, the different parts of the system; (2) knowledge of the basic objectives of the decision maker managing such enterprise; and (3) under...

The objective of this study was to predict the in vitro gas production and the estimated metabolisable energy (ME), crude protein (CP) and neutral detergent fibre (NDF) concentrations of kikuyu grass (Pennisetum clandestinum) by near infrared reflectance spectroscopy (NIRS). A total of 288 sample...

Community-based management of natural resources is a priority in Mozambique's policy on forestry and wildlife resources. In essence the government’s policy is to manage the natural resources in partnership with the rural communities and the private sector. This represents a change in policy in th...

A study was carried out to test: (1) if the prediction of in vitro gas production of kikuyu grass (Pennisetum clandestinum) samples by near-infrared reflectance spectroscopy (NIRS) could be improved by the use of a spectrally-structured sample population; and (2) if the parameters from exponentia...
