Conservation tillage has been widely recommended for implementation in the U.S. for its environmental benefits. The effect of conservation tillage on crop yield is a subject of continued concern amongst farmers who have not adopted the practice. Previous empirical research on the yield...

The purpose of this paper is to evaluate the degree of dicotyledonous weed species of maize culture, the effectiveness of weed control products and the evaluation of maize yield. Experimental factors A-treatment variants: a1-pre-emergence herbicide with Tender 1.5 l/ha + Merlin Flex 0.4 l/ha...

Almost all countries worldwide are impacted by climate change driven events such as heat waves, droughts, sandstorms and flooding. Being one of the most impacted sector, the agriculture industry needs to develop strategies to adapt to climate change. In semi-arid and arid areas, these strategies...

Tanzania's economy is heavily dependent on rainfed agriculture thus, climate variability has a strong impact on crop production. This study aims to assess the effects of climate variability on maize yield in Tanzania. Regression, co integration and ARIMA models were applied. The regression...

We conduct an econometric analysis of the factors influencing U.S. corn and soybean yields using U.S. county level data from 1977 to 2007 and evaluate the likely effects of future climate change on U.S. crop yields based on the projected climate changes by IPCC (2001) and our estimated...
