Agriculture is an important engine of growth and poverty reduction in much of Africa, Nigeria inclusive. But the sector is underperforming in part because women, who are often crucial resource in agriculture and rural economy, face constraints that reduce their productivity. An understanding of these constraints is a prerequisite to devising policies to improve agricultural production and produ...

The purpose of this study was to measure the technical efficiency of canola farmers and determine the underpinning factors. Required data were collected using stratified random sampling method and questionnaire survey. In this context, 157 canola farmers from Tabriz County, Iran, were asked to fill out the questionnaire in 2012-2013 growing season. The technical efficiency was evaluated using s...

Investing in research and development spending (R&D) affects total factor productivity (TFP).Recently new theories of economic growth have emphasized the relationship between R&D and TFPand also identified a number of channels through which a country’s R&D affects TFP of its tradepartner. This study seeks to estimate the effect of agricultural R&D and education spending and someother factors on...

Most producers use herbicides to manage weed infestations. Generally, herbicides are applied at a uniform rate to the entire field. However, a uniform application may not be appropriate for all areas of a field. As precision agriculture technologies have developed, site-specific management of most agricultural inputs, including herbicides, has become feasible. Differentiated application of herb...

A worldwide proliferation of harmful (toxic, food-web altering, hypoxia-generating) algal blooms (HABs) has been linked to human nutrient (phosphorus (P) and nitrogen (N)) overenrichment. In addressing this pressing environmental and human health issue, reducing P inputs has received the most attention, in part because this nutrient was first identified as driving eutrophication (1), and becaus...

A representative sample of 49 state and collective farms in Ukraine provides data in physical units on livestock and crop production and input use for 1989-92. The changes in production efficiency for beef, pork, dairy, winter wheat, grain, and potato production, investigated using stochastic frontier methods, show declining technical efficiency in livestock production and especially low margin...
