Hansen, M. J., Owens, V. N., Beck, D. and Sexton, P. 2013. Suitability of cover crop monocultures for late-season forage in South Dakota. Can. J. Plant Sci. 93: 589–597. Cover crops provide many agronomic benefits and can produce large amounts of forage that is suitable for grazing. The objectives of this study were to determine (1) suitable cover crop forages based on yield and nutrient values; and (2) changes in feed value and yield of these crops through the late fall. Five cover crop monocultures consisting of lentil (Lens culinaris Medikus), cowpea (Vigna unguiculata L.), foxtail millet (Setaria italica L.), oats (Avena sativa L.), forage radish (Raphanus sativus L.), and a mixture of these crops were planted after winter wheat (Triticum aestivum L.) harvest in 2010 and 2011 in central and southeastern South Dakota. Forage data were collected on approximately Oct. 01, Nov. 01, and Dec. 01 each year. Yields increased after the first harvest date at both sites, both years. Oats, radish, and the cover crop mixture all yielded >4000 kg of dry matter per hectare on the second harvest date in 2011 in central South Dakota and radish and oats yielded >4000 kg ha−1 in southeastern South Dakota on the second and third harvest dates, respectively. Forage quality tended to decrease after each harvest date. Radish in central South Dakota in 2010 had the highest protein values for the study (194–313 g kg−1) whereas oats in southeastern South Dakota had the lowest protein concentrations (63–108 g kg−1), both years. All cover crops except cowpea were viable forages through the late fall when they had good establishment with the potential need for protein supplementation with oats, foxtail millet, and the cover crop mixture, depending on animal requirements.

Legume Cover Crop

The influence of winter legume cover crops and of tillage on soil populations of fungal genera containing plant pathogenic species in the subsequent summer sorghum crop were examined in field studies. Legume cover crops significantly increased populations of Pythium spp. throughout the sorghum crop compared with a rye cover crop or no cover crop. This stimulation of the populations of Pythium spp. was not solely due to colonization of cover-crop residue, as populations were significantly greater at the time the legume cover crop was desiccated. Removal of aboveground residue generally decreased populations of Pythium spp. in soil. Incorporation of residue by tillage increased populations of Pythium spp. at some sampling dates. Legumes differed in the magnitude of stimulation, with hairy vetch stimulating Pythium spp. more than crimson clover. Cover crop treatments did not consistently influence soil populations of Fusarium spp., Rhizoctonia solani, Rhizoctonia-like binucleate fungi, or Macrophomina phaseolina. Macrophomina phaseolina populations were significantly greater under no tillage.

Abstract A commercial sunflower field near Mina, in north-central South Dakota, was selected foi our trial of several insecticide treatments at standard and reduced rates for management of SB larvae. The experiment was arranged in a RCBD with 4 replications, and individual treatment plots were 25 ft long by 10 rows (38 inch spacing) wide. In addition, each plot was bordered by two buffer rows to prevent drift. Pre-application evaluations were carried out using whole-plant visual counts of the number of live SB larvae per plant. Twenty plants were examined from each treatment plot and these counts indicated an average of 11 SB larvae per plant within the test area. Treatments were applied on 11 Ju’ using a CO2-propelled backpack sprayer system with a hand-held 6.7-ft long boom. The boom was equipped with 4 TeeJet 8001 nozzles spaced 20 inches apart, and was calibrated to deliver a spray volume of 15 gpa while traveling at 3 mph. Insecticide efficacy was evaluated at 6 DAT using the same count ing technique and number of samples described for pre-application sampling. Data were analyzed with SAS’ s General Linear Models procedure and means were compared using DMRT.
