Abstract
Water and fertility management of processing tomatoes were studied with high frequency subsurface drip (SSD), high frequency surface drip (HFSD) and low frequency surface drip (LFSD). In 1984 and 1985, N, and N + P were injected uniformly through the drip systems, respectively.
In 1987 N + K were injected uniformly through the drip systems, and the subtreatments were 0, 15, and 30 mg/1 P injected daily in the irrigation water.
The yields for all main treatments increased with injected P (1985) and K 1987). The SSD out-yielded the HFSD and LFSD in 1985 and 1987 when P was injected with the irrigation water but was not different in 1984 when only N was injected.
