Transpiration Evaluation of Corn Grown on a Plastic‐Covered Lysimeter

Abstract

Corn grown on plasticcovered monolith lysimeters at Coshocton showed that a very good crop was produced using only the water stored in the soil. A yield of 125 bush els per acre was obtained by using only 8.5 inches of

Effect of Soil Temperature on Grain Sorghum Growth and Yield1

“…The extra moisture conserved by the plastic probably had no more effect on yield than supplemental irrigation, which accounted for only a small yield increase with grain sorghum in 1959. 6 Wateruse efficiency (pounds grain per inch of water) was as follows: CL-CC ( 428) ; CL-MC ( 408); BL-CC ( 388); BL-MC (363); and BARE (315).…”

Global synthesis of vegetation control on evapotranspiration partitioning

“…Because of the importance of separating E and T , there are many studies focusing on ET partitioning in both agricultural setting [e.g., Harrold et al ., ; Sakuratani , ; Yunusa et al ., ] and natural systems [e.g., Sammis and Gay , ; Kelliher et al ., ; Oren et al ., ; Wilson et al ., ; Wang et al ., ] from plot to ecosystem scale. Some recent works have aimed at developing new tools capable of partitioning ET components at the landscape scale [ Scanlon and Kustas , ; Wang et al ., ; Good et al ., ].…”

Evapotranspiration Partitioning in Surface and Subsurface Drip Irrigation Systems

“…In many cases such as design of irrigation system, measurement of the whole ET is sufficient but when the research on water consumed by crop become more precise measurement or estimation of its www.intechopen.com Evapotranspiration -From Measurements to Agricultural and Environmental Applications 212 two components, E s and T c , will be valuable. Prime attempts to partition ET include methods covering the ground surface of a plot to eliminate E s and measure water loss by crop (Tc) and compare it with water loss by uncovered plot (ET) to reach E s (Harrold et al, 1959;Peters and Rassel, 1959;Shaw, 1959). The researches showed, applying ground cover to partition ET changes the field and soil surface energy balance and does not estimate crop transpiration accurately in natural condition ((Fritschen and Shaw, 1961).…”
