Abstract
An important aspect for the optimization of productivity and diffusion of asparagus in Argentina depends on which hybrid to sow.
The aim of this paper is to evaluate the productivity of 13 green asparagus hybrids within the framework of the Fourth International Asparagus Cultivar Trial, one year after planting.
A trial with four random blocks was planted on 16/11/2011 at the Experimental Field Unit, Faculty of Agronomy, UNCPBA (36°48S and 59°51W) with a density of 23,810 plants ha‑1. The genotypes planted included European (Italo, Vittorio, Eros, Ercole, Giove and Franco), Asian (Chino), and American (Early California, UC-157, Patron, NJ-1189, NJ-1123, and NJ-1192) cultivars with a total planted area of 1690 m2. Harvesting was performed in the period 10/09/2012-01/10/2012. The variables studied were: total productivity (PFT), total number of spears (NTT), average spear weight (PPT), and caliber distribution.
Analysis of variance (ANOVA) and least significant difference (LSD) were applied.
Averaged for all hybrids, the following were obtained, for PFT: 931 kg ha‑1, for NTT: 63932 spears ha‑1, and for PPT: 12.7 g spear‑1. For PFT, the hybrids Patron, NJ-1123, UC-157, Early California, Italo and Vittorio had the best total productivity.
For NTT, the most productive hybrids included Patron, followed by UC-157, NJ-1123, Early California, Vittorio, and Italo. Regarding the distribution of calibers, the only hybrid that produced Jumbo was Franco. For extra-large spears, NJ-1123 and Italo performed best, followed by Patron and Early California. For large spears, Patron, NJ-1123, Early California, Italo, Vittorio, and UC-157; for medium spears, Patron, UC-157, Early California, Italo, and Ercole. Finally for small spears, UC-157, Patron, Early California, Ercole and Italo. From this preliminary evaluation, Patron, UC-157, Italo, NJ-1123, and Early California would be the most appropriate hybrids for growing green asparagus at Azul, Argentina.
