Fumigation with methyl bromide (MB) is practiced to control pepper (Capsicum annuum L.) collapse disease, but in P-sorbing soils the plants grow poorly after fumigation. A field trial was conducted on a high P-sorbing soil (fossiliferous Typic Torriorthents) to compare P-fertigation effects on plants grown on fumigated soil subsequently inoculated with Glomus macrocarpum Tul. & Tul. [MB plus vesicular-arbuscular mycorrhizal fungus (MB + VAMF)] and not inoculated (MB), and on nonfumigated soil (NF). Pepper plants in MB-VAMF were most mycorrhizal, and MB plants the least. Both VAMF inoculation and P fertigation controlled early season stunting. Plants fertigated with 1.3 mmol P L-1 weighed the most 9 weeks after seeding, and among them the MB + VAMF plants were the heaviest. After 9 weeks, all plots were fertigated with 0.6 mmol P L-1. Yields were high (61 to 65 Mg ha-1) where 0.4 mmol P L-1 and more was supplied early in the season, and highest (73 to 74 Mg ha-1) where both P fertigation and VAMF inoculation were used. The presence of significant quantities of mycorrhiza early in the growth season inducet the highest percentage of large-size fruit, thus making P fertilization with VAMF inoculation most beneficial. Phophorus fertilization recommendations may have to be adjusted when used in conjunction with soil treatments that significantly reduce VAMF populations in the soil. |
