Article
Full-text available
A number of studies have investigated the impact of using Bt technology on the mean and variance of yields. Yet, many of these studies have not looked at its impact on yield skewness and its damage abating nature. Using a stochastic production function estimation approach that allows for examining the skewness effects of Bt within a damage abatemen...

Full-text available
We examine the origins, implications, and consequences of yield-based N fertilizer management. Yield-based algorithms have dominated N fertilizer management of corn (Zea mays) in the United States for almost 50 yr, and similar algorithms have been used all over the world to make fertilizer recommendations for other crops. Beginning in the mid-1990s...
Article
Full-text available
The site-specific nutrient management (SSNM) strategy provides guidelines for effective nitrogen, phosphorus and potassium management to help farmers make better decisions on fertilizer input and output levels in rice (Oryza sativa) production. The SSNM fertilizer recommendations are based on the yield goal approach, which has been frequently cited...
Thesis
Full-text available
This paper evaluates an old and widely accepted rule of thumb for fertilizer recommendations from Stanford (1973): apply 1.2 pounds of nitrogen (N) fertilizer per bushel of corn expected. While algorithms similar to the “1.2 Rule” have been used for the past four decades all over the world to make fertilizer recommendations for various crops, littl...
Article
This study estimates the impact of the adoption of SSNM practices on rice production of smallholder farmers in Vietnam using cross-section household data (n = 371) gathered from the provinces of Ha Nam and Ha Tay in the Red River Delta. Specifically, it investigates the economic impact of SSNM, focusing on SSNM-induced changes in the yield, profit,...
Article
Full-text available
This article evaluates the impacts of a controlled irrigation technique in rice production called alternate wetting and drying (AWD). Propensity score matching (PSM) and regression-based approaches applied to farm-level survey data are used to achieve the objective of the study. The PSM and regression-based approach accounts for the potential bias...

Using panel data econometric techniques and propensity score matching procedures, this study evaluates the impact of the MAUNLAD agricultural development program - a program designed to help alleviate poverty in Philippine coconut-producing communities. Our results indicate that the program had a significant positive mean effect on the recipients'...

Project
OPTAIN aims to (i) identify efficient techniques for the retention and reuse of water and nutrients in small agricultural catchments across Continental, Pannonian and Boreal biogeographical regions of Europe, taking into account potential synergies with existing drainage-irrigation systems, and - in close cooperation with local actors - (ii) select Natural/Small Water Retention Measures (NSWRMs) at farm and catchment level and optimize their spatial allocation and combination, based on environmental and economic sustainability indicators.
Project
Scientists from NIBIO and CAAS are working together using innovative technologies in order to improve productivity, food safety and sustainability in Chinese agriculture.
Project
The overall goal of SPEAR is to provide science-based frameworks and indicators capable of monitoring and evaluating improvements in productivity and quality of livestock and poultry value chains. SPEAR will evaluate the LPVCs in Senegal, Ghana, and Kenya.
