Abstract:
A field trial was carried out at Azul (36°48',lat.S-59°51',long.O) consisting of asparagus hybrids ‘Italo’, ‘Vittorio’, ‘Eros’, ‘Ercole’, ‘Giove’, ‘Franco’, ‘Chino’, ‘Early-California’, ‘UC-157’, ‘Patrón’, ‘NJ-1189’, ‘NJ-1123’ and ‘NJ-1192’, planted on 16/11/2011 with density 23.810 plants.ha(-1). Characters scored between 19/8/2016-17/11/2016 were: total fresh commercial productivity (TFCP), long and short spear fresh commercial productivity (LSFCP-SSFCP), total commercial spear number (TCSN), long and short commercial spear number (LCSN-SCSN), mean spear weight (MSW) and calibre distribution, CD (J: Jumbo; XL: Extra-Large; L: Large; M: Medium; S: Small y A: Asparagina). Spears were cut, selected (long: 22cm, short: 17cm), weighed, counted, washed and calibrated, and ANOVA-LSD (P≤0.05) employed. Overall mean values were: TFCP:5117,10 t ha-1, TCSN:284910 spears and MSW:18 g spear-1. For TFCP, ‘Vittorio’:6072, ‘UC-157’:6006, ‘Eros’:5885, ‘Franco’:5745, ‘NJ-1123’:5573, ‘Early-California’:5359 and ‘NJ-1192’:5284 kg ha(-1) exceeded the mean. For LSFCP, ‘UC-157’:4250(a), ‘Vittorio’:4134(ab), ‘Franco’:4056(ab), ‘Eros’:3978(ab), ‘NJ-1192’:3861(abc) and ‘Early-California’:3744(abc) excelled and for SSFCP, ‘NJ-1123’:1985(a), ‘Vittorio’:1983(ab), ‘Eros’:1907(abc), ‘Italo’:18174(abcd), ‘UC-157’:1755(abcde), ‘Franco’:1688(abcde) and ‘Early-California’:1615(abcde). For TCSN, ‘UC-157’:356343, ‘Patrón’:341991, ‘NJ-1192’:324675, ‘NJ-1123’:308022, ‘Franco’:307671, ‘Early-California’:307359, ‘Vittorio’:306306, ‘Ercole’:300027 and ‘Eros’:289497 exceeded the mean. For LCSN, ‘UC-157’:230334(a), ‘Patrón’:219336(ab), ‘NJ-1192’:216996(ab) and ‘Franco’:200343(abc) excelled and for SCSN, ‘NJ-1123’:129012(a), ‘UC-157’:126009(a), ‘Patrón’:122655(a), ‘Early-California’:111345(ab), ‘Eros’:110175(ab), ‘Ercole’:110019(ab), ‘Vittorio’:109317(ab), ‘Italo’:108342(ab), ‘NJ-1192’:107679(ab) and ‘Franco’:107328(ab). For CD, 48% were larger calibres and 43% smaller; the following performed well for J: ‘NJ-1189’(a), ‘Eros’(ab), ‘Giove’(abc), for XL: ‘Eros’(a), for L: ‘Franco’(a), ‘Eros’(a), ‘Ercole’(a), ‘Vittorio’(ab), ‘UC-157’(ab), ‘Early-California’(abc), ‘NJ-1123’ (abc), for M: ‘Ercole’(a), ‘UC-157’(a), ‘Patrón’(ab), ‘NJ-1123’ (abc), ‘Franco’(abc) and for S: ‘Patrón’(a). From these results, it can be discerned that (i) a group of five hybrids (‘Vittorio’, ‘Eros’, and ‘Franco’ =Italian), and ‘UC-157’ and ‘Early-California’ =USA) were high performing for all three productivity measures (TFCP-LSFCP-SSFCP); (ii) an additional hybrid, ‘Patrón’, gave high spear number for all three measures (TCSN-LCSN-SCSN); (iii) the hybrids varied considerably in their calibre distribution; and (iv) the hybrids provided a range of different production options for existing and potential growers.
