Arkansas Cotton Variety Test 2007, Fred M. Bourland, A. B. Beach, J. M. Hornbeck, A. J. Hood Feb 2008

Arkansas Cotton Variety Test 2007, Fred M. Bourland, A. B. Beach, J. M. Hornbeck, A. J. Hood

Arkansas Agricultural Experiment Station Research Series

The primary goal of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas. This information helps seed companies establish marketing strategies and assists producers in choosing varieties to plant.


Effects Of Storage Temperature And Duration On The Milling Properties Of Rice, Tanya Pereira, Nora Cooper, Terry Siebenmorgen Jan 2008

Effects Of Storage Temperature And Duration On The Milling Properties Of Rice, Tanya Pereira, Nora Cooper, Terry Siebenmorgen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

To maximize rice quality, it is essential to quantify the various factors that affect milling properties of rice. Rice aging, a process during which rice undergoes a series of chemical and physicochemical changes, affects head rice yield (HRY) and the rate at which HRY changes with degree of milling (DOM). This study examined effects of storage duration (0, 2, and 4 months) and storage temperature (4, 21, and 35°C) on milling properties of ‘Wells’ (long-grain) and ‘Jupiter’ (medium-grain) rice cultivars. In general, HRY increased with storage duration, most significantly for Wells cultivar. Millability curves were developed by plotting HRY vs. …


Arkansas Endemic Biota: An Update With Additions And Deletions, H. Robison, C. Mcallister, C. Carlton, G. Tucker Jan 2008

Arkansas Endemic Biota: An Update With Additions And Deletions, H. Robison, C. Mcallister, C. Carlton, G. Tucker

Journal of the Arkansas Academy of Science

It has been over a decade since the publication of Robison and Allen (1995) that provided the definitive list of endemic flora and fauna of Arkansas. The present study brings up-to-date the endemic biota of the state. Since 1995, several new species have been described and new discoveries have been made, adding species to the state biota. Other species are deleted and new distributional information on other state endemics is presented. Specifically, 3 new plant species are added to the state list while 4 plant species are deleted. Sixteen new animal species/subspecies are added to the state list while numerous …


Geographic Variation In The Pollination Biology Of Passiflora Lutea (Passifloraceae), J. Burks Holland, J. Lanza Jan 2008

Geographic Variation In The Pollination Biology Of Passiflora Lutea (Passifloraceae), J. Burks Holland, J. Lanza

Journal of the Arkansas Academy of Science

Like most species of Passiflora, P. lutea is reported to produce one-day flowers with complicated floral movements and requires deposition of non-self pollen for fruit production. Medium sized bees are the most likely pollinators in central Texas. We report on a series of observations and experimental manipulations that compare the reproductive biology of P. lutea in central Arkansas to that reported previously from plants about 800 km distant in central Texas. We observed floral movements and floral visitors, compared fruit production of flowers available to pollinators versus flowers from which pollinators were excluded, and compared fruit production of flowers that …

The Effect Of Austrian Winter-Pea Cover Crop And Cow-Pea Companion Crop On Corn Yield, Matthew Marsh, David Longer, Vaughn Skinner Jan 2008

The Effect Of Austrian Winter-Pea Cover Crop And Cow-Pea Companion Crop On Corn Yield, Matthew Marsh, David Longer, Vaughn Skinner

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Leguminous cover crops have the potential to combat the rising input cost of commercial nitrogen (N) fertilizers. This experiment examines benefits of implementing a leguminous cover and/or companion crop into a corn production system. Legumes biologically fix nitrogen from the atmosphere, adding to the nitrogen content of the soil. In this experiment Austrian winter peas (Pisum arvense) (AWP) were used as the leguminous cover crop and cowpeas (Vigna unguiculata) were used as the companion crop. A two year experiment was carried out in which winter peas were planted on half the field in the fall and allowed to grow until …


Investigating The Utilization Of Silica Gel Packets In Drying Research-Scale Rough Rice Samples, Ashley Wiedower, George Ondier, Terry Siebenmorgen Jan 2008

Investigating The Utilization Of Silica Gel Packets In Drying Research-Scale Rough Rice Samples, Ashley Wiedower, George Ondier, Terry Siebenmorgen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Rice moisture content (MC) must be reduced to approximately 12.5% MC to prevent spoilage during storage. Desiccants may provide an improved method for drying research-scale rice samples. This study investigated the effects of 1) rice mass to be dried, 2) placement method of silica gel packets in rice samples, 3) regeneration and re-use of the packets, 4) drying temperature, and 5) initial MC on the effectiveness of silica gel packets to dry rough rice samples to the desired 12.5% MC. Multiple masses (200, 500, and 1000 g) of long-grain rice samples were dried using three desiccant placement treatments: 1) intimate …
