![]() The combination of pathogens leads to disease known as Bovine Respiratory Disease Complex and costs the cattle industry billion-dollar yearly losses. is able to colonize the lower respiratory tract and become virulent. However, when the immune system is depressed by viral infection, M.h. Mannheimia haemolytica (M.h.) is a gram-negative bacteria that normally lives in the upper respiratory tract of cattle. The virus can suppresses the animals' immune system, rendering them susceptible to other infections. The relationship between roots, water availability, and temperature will be valuable in making decisions such as planting dates.īovine herpesvirus-1, or BHV-1 infects cattle. In addition to this it is expected that the cultivars will perform based on their breeding origin the cultivars from Arizona and New Mexico will do well in the drought stressed units. It is expected that the plants in the well watered, optimal temperature units will be healthier than the plants in the drought stressed or lower temperature units. Twenty days from the time of planting the plants will be pulled up in order to scan the roots. Time of seed sprout, soil moisture, and evapotranspiration measurements were taken. Nine cotton cultivars from nine different breeding programs in nine different states were grown in a pure sand soil under these conditions. An experiment was conducted by varying night and day temperatures (22/14, 30/22 degrees Celsius), and by varying water availability (well watered, drought stress). Better understanding of cotton's roots during drought and low temperatures is needed in order to grow it more effectively. ![]()
