Yield and Quality Response of Florunner Peanut to Applied Drought at Several Growth Stages1

Autor: J. R Stansell, J. E Pallas

Publikováno v: Peanut Science. 12:64-70

Florunner peanuts (Arachis hypogaea L.) were subjected to 35 and 70-day drought periods during several growth stages (days after planting). Drought conditions were maintained by the use of automatic rainout shelters covering groups of drainage lysime

Tracking the elemental content of leaves and other plant parts of the peanut under irrigated culture in the sandy soils of South Georgia

Autor: J. E. Pallas, J. R. Stansell, J. B. Jones

Publikováno v: Communications in Soil Science and Plant Analysis. 11:81-92

Tracking the nutrient element content of peanut leaves over the entire fruiting season revealed significant changes in certain essential elements during short periods. These short‐term changes may be more influential on yield than the general chang

Photosynthetic Response of Peanut 1

Autor: Y. B. Samish, J. E. Pallas

Publikováno v: Crop Science. 14:478-482

The net photosynthetic rates of nine genotypes of the cultivated peanut (Arachis hypogaea L.) grown under controlled conditions were measured at six different light intensities: 180, 255, 526, 784, 1098, and 1546 µE m−2 sec−1 (E = einsteins). Al

Water and nutrient element regulation prescription in nonsoil media for greenhouse crop production

Autor: R. R. Bruce, J. E. Pallas, L. A. Harper, J. B. Jones

Publikováno v: Communications in Soil Science and Plant Analysis. 11:677-698

The regulation of water and nutrient elements in nonsoil, solid media for crop production in a greenhouse is examined in relation to parameters of the plant‐media‐water system. Physical and chemical characteristics of the media and crop character

Photosynthetic Traits of Selected Peanut Genotypes1,2

Autor: J. E. Pallas

Publikováno v: Peanut Science. 9:14-17

These studies were undertaken to identify photosynthetic traits of the cultivated peanut (Arachis hypogaea L.) that might be used in breeding programs designed to increase yield. Net photosynthesis (Pn), CO2 compensation point (Γ), stomatal diffusio

Effects of Drought on Florunner Peanuts 1

Autor: J. R. Stansell, T. J. Koske, J. E. Pallas

Publikováno v: Agronomy Journal. 71:853-858

Droughty conditions are implicated in causing low yields, poor grades and germination, and an increased incidence of aflatoxin in the peanut (Arachis hypogaea L.). However, very little is known as to when in the growth cycle drought is most critical.

Publikováno v: Peanut Science. 3:44-48

Three peanut (Arachis hypogaea) varieties were maintained at soil water levels ranging from moderately wet to very dry. Pod yield and quality were significantly reduced in treatments receiving less than about 30 cm of water during the growing season.

Publikováno v: Journal of the American Society for Horticultural Science. 104:659-663

Glasshouse microclimate during 3 growth periods in the Southern Piedmont region of the United States was characterized. An increase in density of tomato plants (Lycopersicon esculentum Mill.) by one-third, which doubled radiation interception, was su
