Switchgrass Production in Marginal Environments: A Comparative Economic Analysis across Four West Tennessee Landscapes

open access: yes
Switchgrass (Panicum virgatum L.) has been identified as a model feedstock for the emerging biofuels industry. Its selection was based, in part, upon the observation that switchgrass can produce high yields in marginal production environments. This trait

Effect of source and rate of nitrogen fertilization on yield, fruit quality and leaf mineral composition of valencia orange trees grown in Riyadh, Saudi Arabia

open access: yes, 1997
This investigation. was carried out during 1992 and 1993 seasons to study the influence of ammonium sulfate and urea at different rates (0, 250, 500, 750, and 1000 g N/tree) on the yield, fruit quality and leaf mineral composition of Valencia orange ...

NITROGEN FERTILIZATION IN WET AND DRY CLIMATE

open access: yes, 2007
Fertilization may help crops to yield better. To determine whether meteorological and soil conditions influence the productive response of nitrogen fertilization in sunflower, a study was conducted in an Italian interregional project ...

Determining Optimal Levels of Nitrogen Fertilizer Using Random Parameter Models

open access: yes
The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nstochastic ‘‘limited’’ stochastic. In this study, we estimate rye– ryegrass yield functions in which all parameters are random.
