| Popis: | New Jersey 'Syn 4' asparagus (Asparagus officinalis, L.) was grown on a sandy loam soil to compare plant survival and yield of asparagus grown from crowns and transplants under four irrigation treatments: sprinkler (SPR), surface trickle (ST), subsurface trickle (SST), and no irrigation (NI). While plant survival of crowns was not appre- ciably influenced by any irrigation treatment, survival of transplants was significantly increased by SST. Total and marketable yields from crowns and transplants were similar in the first harvest season (year 3). However, in years 4 and 5, the yield of crowns was higher than that of transplants. Subsurface trickle increased yield from transplants in years 4 and 5 and increased yield from crowns in year 5. All irrigation methods significantly increased both spear production (spear/ha) and average spear weight. Subsurface trickle irrigation resulted in the largest increase over NI in total yield and spear production. The yield of many hybrid asparagus cultivars is higher than that of older, open-pollinated cultivars (Benson and Takatori, 1980; Damicone and Manning, 1987; Mapplebeck and Tiesson, 1983; Price, et al., 1986). Although transplanting crowns is the primary method of establishing commercial asparagus plantings (Kirpes et al., 1985, Mapplebeck and Tiessen, 1983), the lim- ited seed supply and grower interest in rapid establishment of these new cultivars has resulted in increased interest in using asparagus transplants. Use of greenhouse-grown transplants re- duced risk of infection by fusarium wilt and crown rot (F. ox- ysporum and F. moniliforme), increased mechanization of planting, reduced planting time and labor, and more efficiently used expensive hybrid seed (Ombrello and Garrison, 1978; Fisher |
