Establishment and Yield of Asparagus as Influenced by Planting and Irrigation Method

Abstract

<jats:p><jats:italic>New</jats:italic> Jersey `Syn 4' asparagus <jats:italic>(Asparagus officinalis,</jats:italic> 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 appreciably 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.</jats:p>

Cost-effectiveness of postharvest drip irrigation of chosen North-American cultivars of asparagus grown for green spears in open field technology in the Central Poland

“…Rolbiecki and Rolbiecki, 2008; Rolbiecki, 2013). The results obtained were similar to those reported by Paschold et al (1996Paschold et al ( , 1999Paschold et al ( , 2008 and other foreign authors (Roth and Gardner, 1989;Sterrett et al, 1990;Drost and Wilcox-Lee, 1997;Drost, 1999).…”

Growth of asparagus in a commercial peat mix containing vesicular-arbuscular mycorrhizal (VAM) fungi and the effects of applied phosphorus

“…Precipitation during transplant establishment in the field was below the monthly mean for July (9.5 cm deficit) and August (7.1 cm deficit). In fact, field surface trickle irrigation in the field does not appear to improve survival or growth of asparagus transplants as does subsurface trickle irrigation (Sterrett et al, 1990). The increased survival of the preinoculated plants compared to the control after 14 months in the field for both tissue-cultured plants and those started from seed may be associated with the drought conditions in the first year of growth.…”

Response of Chosen American Asparagus officinalis L. Cultivars to Drip Irrigation on the Sandy Soil in Central Europe: Growth, Yield, and Water Productivity

“…Drost [31] reported that under dry climatic conditions, lowering sandy soil moisture below −50 kPa reduced the number and height of stalks in comparison to drip-irrigated variants. Sterrett et al [30] obtained an increase in stalk number due to irrigation, on average, of four stalks per plant, and Battilani [32] obtained an increase of one stalk per plant. The diverse response of asparagus cultivars to drip irrigation has been confirmed, i.a., by the results of Dutch [33] and Polish [14] studies.…”

“…Some researchers have also shown a significant impact of irrigation on the height of summer stalks in the year preceding the harvest. For example, in the third and fourth year of cultivation, Drost and Wilcox-Lee [29], Hartmann [8,9], Pardo et al [27], Paschold et al [12], and Sterrett et al [30] obtained an average increase in summer stalk height of 14 cm in comparison to non-irrigated control variants.…”

Postharvest drip irrigation, applied in the growing season preceding the next asparagus harvest, significantly increased the number of asparagus summer stalks per plant for the studied cultivars and years, on average, from 7.9 to 11.1 (Table 8).…”
