Synopsis Irrigation was effective in increasing total forage production in 1957 but not in 1958. In both years, however, irrigation prior to the first harvest did not increase yields. Deep fertilization was ineffective in increasing forage production. Alfalfa, alone and with orchardgrass, was the only species whose root yield was increased by deep fertilization. Alfalfa, alone and with orchardgrass, made the best use of available subsoil moisture; orchardgrass made the least use of this moisture.
