Can outsourcing pest and disease control help reduce pesticide expenditure? Evidence from rice farmers

open access: yesAgribusiness, EarlyView.
Abstract Outsourcing pest and disease control (PDC) has grown rapidly worldwide, especially in developing countries. Although numerous studies have investigated various advantages of outsourcing PDC, little is known about its impact on pesticide expenditure.

Do floral syndromes predict specialisation in plant pollination systems? Assessment of diurnal and nocturnal pollination of escallonia myrtoidea [PDF]

open access: yes, 2006
Pollination syndromes lead to questions concerning the role of different suites of pollinators on the pollination success of plants. Escallonia myrtoidea exhibits floral traits associated with pollination by diurnal butterflies; however, flowers remain ...

Assessment of Pollen Limitation and Pollinators’ Contribution in Soybean (Glycine max)

open access: yesPlants
Soybean (Glycine max) is a predominantly self-pollinating crop; however, its flowers exhibit traits associated with insect pollination. While several studies report yield benefits from floral visitation, others suggest little or no effect, and few have ...

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Effects of pollination treatments (spontaneous self-pollination vs. hand cross-pollination) on reproduction of Chaetanthera renifolia.

open access: yes, 2013
Mean percentage of achene set and achene weight at La Parva (A and C) and Piedra Numerada (C and D). Open bars: autogamous self-pollinated (n = 18); Grey bars: hand cross-pollination (n = 18). Bars are means ± SE.

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...
