Efficient grazing management programs cannot succeed without proper stocing rates. However, proper stocking rate alone will not insure a successful grazing program. Successful grazing management only occurs when all factors affecting production are manipulated properly: season of use; kind, class, and/or combination of animals; grazing distribution; grazing program; fertilization; pest control; and water management as well as stocking rate. The following suggestions in this circular are a guide to initial planning of new pastures and the modification of existing grazing programs.
Photoperiod Requirements For Flowering And Flower Production In Soybean, John Settimi, James Board
Photoperiod Requirements For Flowering And Flower Production In Soybean, John Settimi, James Board
John R. Settimi
Photoperiod has been recognized as playing a major role in soybean [Glycine max (L.) Merr.] growth and development. The objective of these studies was to determine the number of short days (13.5h) representative of early spring daylengths in the southeastern United States necessary to cause anthesis and adequate flower production in soybean. Growth chamber studies were conducted at the Phytotron at North Carolina State University, during the first 26 wk of 1985. The soybean cultivar Tracy-M and the delayed flowering genotype D77-12480 were subjected to treatments in which they were transferred either from short-day (13.5-h) to long-day (16-h) or long-day …
Photoperiod Effect Before And After Flowering On Branch Development In Determinate Soybean, John Settimi, James Board
Photoperiod Effect Before And After Flowering On Branch Development In Determinate Soybean, John Settimi, James Board
John R. Settimi
Previous research indicated that restricted branch development was a factor associated with soybean [Glycine max (L.) Merr.] seed yield reductions at late planting dates in the southeastern United States. The present studies were conducted to outline the progress of branch development at different planting dates and to determine the role of photoperiod in branch restriction at late planting dates. In field studies, eight cultivars were planted at early April (nonoptimal), mid-May (optimal), and mid-June (nonoptimal) planting dates in 1982 and 1983 at Baton Rouge, LA (30°N Lat), on an Olivier silt loam (fine-silty, mixed, thermic Aquic Fraguidalf) soil. Plants were …
