An evaluation of soil warming for increased crop production

Creator:

Rykbost, K. A.

Abstract:

In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...

Theoretical and experimental evaluation of transfer of 2, 4-dichlorophenoxyacetic acid in porous media

Creator:

Saxena, Subodh Kumar, 1942-

Abstract:

Experiments were conducted to study the effect of pore size distribution on the diffusion of 2, 4-Dichlorophenoxyacetic acid (carbon- 14) through water saturated porous media. Eight size fractions of glass beads were used representing the porous media. It was found that as the average particle radius, and hence pore radius,...

Physiological effects of water stress on young corn plants

Creator:

Barlow, Edward William Ross

Abstract:

Laboratory experiments were used to investigate the mechanism of plant response to water stress by determining the sensitivity of leaf elongation, photosynthesis and transpiration in young corn plants to a decrease in leaf water potential. In initial experiments, 9 day old corn plants were grown at soil water potentials of...
