This study identifies farm‐specific and market factors affecting the adoption of herbicides and the level of herbicide use by rice farmers in the Philippines. This requires the application of a modified version of Heckman's two‐step method to estimate a random‐effects double‐hurdle model for unbalanced panel data.

In this article, we use a probit model to assess the factors that will influence the decision of Irish farmers to adopt genetically modified (GM) technology should they be given a choice in the near future of selecting between GM and non-GM varieties of crops. The results from the probit model indicate that among the likely early adopters of GM technology in Ireland are farmers with large farm acreage who are specialist crop farmers and who have formal agricultural education together with access to high-quality soils.

Discussion Paper 34 contains information on property relations and profitability of 100Russian large-scale farm enterprises, gathered in interviews in the Volgograd region in 2000.They are an integrated part of research activities concerning the privatisation and restructuringof farm enterprises in Central and Eastern Europe and take up the subject of Discussion Paper18. 31 questions were formulated. The answers were evaluated using multivariate statisticalmethods.

Focus group methodology in a field demonstration setting was used to obtain qualitative data on the perceptions of family forest owners relating to treatment efficiency and feasibility of herbicide control methods. Interviews took place on sites where various strategic herbicide treatments were implemented for Chinese privet (Ligustrum sinense) control using the active ingredients glyphosate and metsulfuron.

A „Gazdálkodás” 2010. évi 2. számában vitacikkem jelent meg „A földbirtok-politikaválaszt igénylő kérdései” címen. Ezzel az volt a célom, hogy a témakörrel kapcsolatban felvessek kérdéseket, leírjak megállapításokat, és ezzel egy olyan vitát generáljak, ami fórumot ad a tudományos közélet szereplőinek a megszólalásra, a vélemények ütköztetésére, egymás nézeteinek jobb megértésére, a politika számára javaslatok megfogalmazására.

The fragmentation of landholdings is considered as disturbing factor for agriculture. The aim of this article is to evaluate the extent of land fragmentation of the large landholdings in Estonia. The Januszewski and Schmook indexes were calculated for that purpose. The detailed survey of three agricultural landholdings was conducted in order to assess the possibilities to reduce the land fragmentation and improve their land use conditions. Results showed that Estonian agricultural producers’ landholdings are considerably fragmented.

Acacia mearnsii De Wild (black wattle) is an important plantation species for tannin production and woodchip exports in South Africa and Brazil. This study provides an updated overview of the black wattle industries in both countries, including planted areas and land ownership, silviculture and management, bark extract production, woodchip exports, as well as key research and development issues. The current total planted area to black wattle is 110 000 ha in South Africa and c. 170 000 ha in Brazil. In both countries black wattle is mainly cultivated by farmers (c.

Nine midwestern states have laws that restrict the involvement of publicly held corporations in agriculture. Opponents argue that the laws' direct efforts to regulate ownership structure may have an adverse indirect impact on size structure. Restricting corporate involvement might stifle the emergence and growth of efficient, large-scale establishments if corporations have advantages over other organizational forms in meeting capital requirements. Since 1982, Nebraska has had an anti-corporate farming law that prohibits corporate ownership of feedlots.

The current biofuel debate is characterized by concerns about the environmental effects of large-scale biofuel plantations, controversies about GMO-based feedstocks and the recent global food crisis. Predictions for the development of the biofuel sector are either departing from the supply-side or the demand-side, but are mostly based on modelling efforts with an unclear experimental basis and only broadly defined economic settings. Results vary widely and tend to undervalue technical progress in processing efficiency or management-related increases in biomass yields.

Hokkaido Island is located in the cool temperate zone, and its climate conditions facilitated the formation of a variety of wetland types, the majority of them peat-forming mires. Most of these remained in a natural state until the early 20th century. However, drainage and subsequent conversion mostly to agricultural land have since destroyed more than 70% of the original wetland ecosystems.

Forests in the Central Hardwood region are undergoing change in terms of area, volume, species composition, and forest structure. These forests are dominated by deciduous species; are increasing their average stand size, volume, and age; and, are experiencing woody plant species replacement as shade intolerant species are being replaced by more shade tolerant species. As changes progress, concerns are being raised regarding the potential for these lands to produce the wide array of benefits associated with timberland.
