ABSTRACT.
Three studies were conducted at Clinton, N.C., to investigate the relationship between number of rows per bed, in-row spacing, and spear yield of asparagus (Asparagus officinalis
L. ) over 11to 13years. In the first study, increasing plant densities from 21,550 to 43,100 plants/ha by doubling the number of rows/bed increased the cumulative yield from 64% to 80% for three hybrid lines ('UC 157', 'WSU 1', and 'WSU 2') but only 6% for 'Rutgers Beacon '.The effects of doubling the plant density were still apparent 13years later. In the second study, yields of 'Princeville' ('Mary Washington' selection) crowns, grown at densities from 14,000 to 86,000 plants/ha, were also increased for 8 years by doubling rows at various in-row spacings. In a third study, in which densities ranged from 21,000 to 387,900 plants/ha, the magnitude of the response to rows/bed was dependent on in-row spacing. Efficient use of bed space and the avoidance of crowding exerted a larger influence on productivity than did average planting density. The yield response to rows/ bed was greater and more persistent through the years for wider in-row spacings. Spear size was only marginally responsive to rows per bed and in-row spacing. |

Objectives: Paratuberculosis (PTBC) is a chronic infectious disease of ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP), with an important economic impact in the dairy sector. This study aimed at evaluating and comparing the performance of two molecular diagnostic tests (PCR and qPCR) for the detection of MAP shedding in feces and milk of seropositive dairy cows across time. |
