| The introduction of agricultural reforms has debatable effects on food security in developing countries. This research investigates how such effects influenced maize supply in two developing countries which were among the first to introduce agricultural reforms. Conclusions from the research suggest that agricultural reforms led to mixed results. This may be attributed to the sometimes stop-go nature of reform implementation. The mixed results are reflected in the weak maize output response to price changes. Overall country economic conditions, state of agricultural development can be attributed to the pace of response, hence effect on agricultural supply. Elasticity of maize output to changes in price and acreage are strongly significant in maize output... |

| The aim of this paper is to identify optional ways of preventing NO3-levels from rising within Croatian farming systems, and the implications from the viewpoint of the manager. More specifically, the purpose is to 1) Determine whether Croatian farmers exceed profit maximising levels of N-fertilizer use in maize cultivation, and its possible influence on NO3 N-levels. 2) To estimate the marginal abatement cost (MAC), at the farm level, of reducing NO3 N leaching through the following instruments: a tax on optimal N-doses, a product tax and an N-fertiliser quota and a requirement for all instruments to correspond to the same abatement level. Based on. N-response experiment from feld trial for maize N-response curves were estimated. A sample of 20... |

| Croatian farming systems have become more intensive in recent years. There is some evidence of rising NO3-N-levels in ground water. The aim of the paper is to find pos-sible ways of preventing NO3-levels to rise in Croatian farming systems and their im-plications from the viewpoint of the manager. More specifically the purpose is to 1. Determine whether Croatian farmers exceed profit maximising levels of N-fertiliser use in maize cultivation and possible influence on NO3-N-levels. 2. To estimate the marginal abatement cost (MAC) at farm level of reducing NO3-N leaching through following economic instruments: a tax on optimal N-doses, a product tax and a N-fertiliser quota, all instruments corresponding to the same abatement level. Based on N-response... |
