By applying variance decomposition technique to the regional data from China, this paper discusses possible impact on Chinese foodgrain production and its variations created by institutional changes, including imposition of procurement quota and the introduction of the agricultural production...

Over the decades to 1980 agricultural marketing and input supply systems came increasingly under official monopolies. Dissatisfaction with the incentives offerred to producers and with the costs to governments has sparked interest in reform. Practicable ways of introducing more competition and...

Variables related to farmers' awareness and attitudes towards intercropping of immature rubber (Hevea brasiliensis) stands, extension contacts, education level, and experience with farming other crops are positively associated with the probability of adoption. Higher levels of off-farm income...

A fairly comprehensive range of planting choices made by maize farmers in Kenya (including discrete endogenous variables creating self-selectivity) is modelled and estimated as one system of interrelated decisions. Two-stage and three-stage probit procedures are used to handle the simultaneity...

The Zambian Government encourages crop production in the Gwembe Valley without taking into consideration the risks involved. These risks mainly originate from the stochastic nature of rainfall. This paper, therefore, identifies optimal cropping patterns in the Gwembe Valley by using Target MOT...

This paper develops a stochastic multi-period decision model to analyse a continuous wheat cropping system infested by wild oats (Avena fatua L.), in southern Australia. The multi-period solutions is obtained by employing a dynamic programming model in conjunction with a bioeconomic simulation...

Previous empirical studies on the relationship between agricultural growth and farm imports in the LDCs suffer from serious methodological defects, which to some extent may invalidate their results and interpretations. This study used Sims' causality test to examine interactions between...

The study investigates the value of additional information on the response function to soil salinity of a given crop (potatoes), with regard to a stochastic long-run optimization model for utilization of saline water in a single-farm framework. The analysis provides a conceptual and...

Rice is the most important staple food in the People's Republic of China (PRC). In many Asian countries rice appears to have become an inferior good, with income increases leading to declines in per capita consumption as other food products are substituted for rice. In this study, human rice...

This paper attempts to contribute to one of the major aspects of international research agenda in agroforestry. A general framework is developed in this paper to capture the dynamic interactions of various components of agroforestry system. Using a multi-seasonal model of agroforestry, the...
