The Effect Of Black Plastic Mulch Alone And In Combination With Various Types Of Plastic Row Covers On Production Of Sweet Corn, Morteza Jabalameli
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effects of black polyethylene (PE) mulch alone and in combination with plastic film tunnels (Agronet, Reemay, whiteperforated, clear, and clear-slitted) were studied on morphology and yield of sweet corn in North Logan, Utah. Yields of "Miracle" sweet corn (Zea mays L.) were increased significantly by using black PE mulch and with a combination of various types of plastic row covers, as compared to unmulched soil. Standard-growth analysis procedures were conducted to verify responses among treatments. Treatment effects were determined by measuring days to first flowering, ear weight, number of side tillers, cob length, cob circumference, cob fill length, number …
Effect Of Feeding A Viable Yeast Culture With Or Without Aspergillus Oryzae On Milk Production, Apparent Nutrient Digestibility, Ruminal Fermentation, And Nutrient Degradability In Holstein Cows, Daeyoon Kim
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Twenty-four early to midlactation Holstein cows were allocated to one of three treatments. Treatments consisted of: 1) basal ration plus 60 g wheat bran per day per head (control); 2) basal ration plus 57 g yeast culture per day per head; 3) basal ration plus 57 g yeast culture plus 3 g Aspergillus oryzae per day per head. Feed intake and milk yield were recoreded daily and milk composition and body weights were recorded weekly. Feed and fecal samples were recorded weekly. Feed and fecal samples were collected to determine apparent nutrient digestibility. No statistical difference was observed in milk …
