Tomatoes (Lycopersicon esculentum Mill.) were grown for two seasons on polyethylene-mulched beds to evaluate metam-potassium (metam-K) as both a fumigant and K source in comparison to metam-sodium (metam-Na) fumigant and KCl fertilizer applied preplant or injected. Treatments without fumigation had significantly lower early yield compared to treatments with metam-Na at 468 or 935 L ha-1 or metam-K at 281 L ha-1 in 1993. There were no significant differences in early yield for 1994. No by-year interaction for total yield were noted so results were combined for both years. Tomatoes grown with metam-Na at 468 L ha-1 produced significantly higher yields than all the other treatments. The leaf K concentration in 1993 was 34 g kg-1 with metam-K at 561 L ha-1 which was greater than treatments with Kcl. However, metam-K showed little advantage in performance over metam-Na as a fumigant or KCl as a fertilizer source. |
