We analysed to what extent the stochastic effects of two biological control agents (i.e. weevils and mycoherbicides) affect the optimal choice of Californian thistle control. A stochastic, dynamic optimisation model was set up to analyse strategies that maximise the expected net present values....

Hybrid rice, one of the viable and proven technologies has been considered as a new frontier to increase rice production for meeting growing demand for staple food in Bangladesh. Using farm survey data this paper examines comparative profitability of hybrid and inbred rice cultivation and...

The development of molecular markers allows plant breeders to identify desirable traits by analysing DNA rather than undertaking field trials or laboratory tests. This capacity provides a potential for a significant changes to occur within plant breeding programs. However, the value of...

A set of simulations were run to estimate the impact on gross margins due to improvements in cattle breeding efficiency and other management factors in extensive pastoral systems in Western Australia. The output from the simulations was integrated into a statistical model of gross margin as a...

To assist in the management of plant breeding programs, and particularly in managing change, the detailed cost structure and the nature of the cost function facing plant breeders need to be known. In this paper, an attempt is made to define a cost function for a representative wheat breeding...

The western NSW rangeland is the pastoral zone of NSW, with increasing abundance and distribution of feral goats (Capra hircus). Feral goats are generally viewed as agricultural pests impacting on agricultural production and natural resources but they are also valuable economic resources that...
