Occurrence Of Diseases And Insect Pests In Select Soybean (Glycine Max (L.) Merr.) And Sorghum (Sorghum Bicolor (L.) Moench) Rotations In Mississippi, Sergio Tomas Pichardo
Occurrence Of Diseases And Insect Pests In Select Soybean (Glycine Max (L.) Merr.) And Sorghum (Sorghum Bicolor (L.) Moench) Rotations In Mississippi, Sergio Tomas Pichardo
Theses and Dissertations
Field and greenhouse studies were conducted during 2004 through 2006 at the Rodney R. Foil Plant Science Research Center, Starkville, MS. Six sorghum and soybean rotation treatments were tested to determine their effect on plant pathogen, insect, and nematode diversity and density levels. Treatments included 1) continuous sorghum, 2) continuous soybean, 3) sorghum-soybean-sorghum rotation, 4) soybean-sorghum-soybean rotation, 5) sorghum-soybean-soybean rotation, and 6) soybean-sorghum-sorghum rotation. Several nematode and insect species were identified during the study, but were always below economic thresholds. Six insect species were identified on soybean during each growing season and used as the indicator species for this study. …

Soybean cultivar performance tests are conducted each year in Arkansas by the University of Arkansas Division of Agriculture. The tests provide information to companies developing cultivars and/or marketing seed within the State, and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for soybean producers.

Management programs aimed at reducing wildlife damage to row crops rely on information concerning the spatial nature of wildlife damage at local and landscape scales. In this study we explored spatial patterns of wildlife damage within individual corn and soybean fields by describing relationships between specific locations where wildlife damage was recorded and distances from such locations to various habitat types that presumably influenced animal abundance and movements in our study area. Using stratified random sampling, we conducted depredation surveys of 100 corn fields and 60 soybean fields from May through October both in 2003 and 2004 and recorded the …

Temperature and photoperiod can be used to simulate soybean (Glycine max [L.] Merr) phenology because they serve as surrogates for complex biochemical pathways leading to the appearance of certain developmental stages at the whole plant level. We developed a soybean phenology model (SOYDEV) which utilizes non-linear temperature and photoperiod functions and separates floral induction and post-induction for simulating time of flowering. This model accurately simulated the dynamics of vegetative development, final node number and the occurrence of major reproductive stages such as flowering (R1), beginning pod (R3), mid-pod elongation (R3,5), beginning seed (R …

The Effects Of Row Spacing On Yield And Yield Components Of Full Season And Double-Cropped Soybean, Sevgi̇ Çalişkan, Mehmet Arslan, İlhan Üremi̇ş, Mehmet Emi̇n Çalişkan
Turkish Journal of Agriculture and Forestry
Compared to full season soybean cropping systems, seed yield reduction is a major concern in double-cropped soybean production systems. This study was conducted at the Research Farm of Mustafa Kemal University, Hatay, Turkey, to determine if it is possible to enhance the yield of both full season and double-cropped soybean by narrowing row spacing. Two soybean cultivars, A3935 and S4240, were planted using row widths of 30, 50, and 70 cm, and twin row (50 25 50 cm) in 2004 and 2005. Seed yield and the other investigated plant parameters of double-cropped soybean were lower compared to full season soybean. …

Seed hardness is an important factor in determining soybean suitability for natto production. There is no established methodology for testing seed texture of soybeans. The objective of this study was to develop an efficient method by examining different instruments and seed parameters that could be potentially used for testing soybean seed hardness. Five food-grade soybean genotypes with different seed sizes were used to determine seed hardness and water-absorption capacity. Water absorption capacity was expressed by swell ratios for seed weight, seed dimension, and volume of water changes before and after soaking. Seed hardness test was conducted by a one-bite method …
The Influence Of Morningglory (Ipomoea Lacunosa), Hemp Sesbania (Sesbania Exaltata), And Johnsongrass (Sorghum Halepense) On Reproduction Of Rotylenchulus Reniformis On Cotton Gossypium Hirsutum L. And Soybean Glycine Max. (L.) Merrill, Michael John Pontif
LSU Doctoral Dissertations
Microplot studies were conducted to evaluate the effects of cotton (LA. 887), soybean (Pioneer 96B21), and three endemic weed species, pitted morningglory (Ipomoea lacunosa), hemp sesbania (Sesbania exaltata), and johnsongrass (Sorghum halepense), on reproduction of the reniform nematode, (Rotylenchulus reniformis). Over two microplot trials the co-culture of cotton with any of the three weeds suppressed numbers of reniform nematode juveniles in soil. When grown singly, reniform nematode reproductive values after 60 days on cotton averaged 69.0, while those for morningglory, hemp sesbania, and johnsongrass averaged 42.0, 23.5, and 18.0, respectively. Reproductive values for cotton co-cultured with morningglory averaged 38.7. Those …
Comparative Genotoxic Potential Of Mercury And Cadmium In Soybean, Girjesh Kumar, Priyanka Rai
Comparative Genotoxic Potential Of Mercury And Cadmium In Soybean, Girjesh Kumar, Priyanka Rai
Turkish Journal of Biology
Genotoxic effects of two heavy metals viz. mercury (Hg) and cadmium (Cd) on somatic and gametic cells of soybean were investigated. Seeds were treated with different doses of these heavy metals. Treatments with Hg and Cd not only reduced the frequency of dividing cells but a wide spectrum of chromosomal abnormalities were also recorded. Pollen fertility was found to be significantly correlated with meiotic irregularities found in the metal treatment sets. It was found that both of these heavy metals are capable of inducing chromosomal aberrations, but Hg is much more genotoxic than Cd, since it induces greater abnormalities.
