In field trials in 1972-5, white dent maize was given (a) 150 t FYM + 60 t urine or (b) 50 t FYM + 20 t urine/ha or (c) 230 kg N + 170 kg P2O5 + 240 kg K2O/ha and harvested at tasseling to early-milk stage. Highest annual DM yield was obtained in 1973 without significant differences between treatments. (a) gave the highest CP yield, especially in 1973, '74 and '75 and CP content was significantly higher with (c) than with (b) in 1972. Herbage Ca content was lower and K and NO3-N content generally higher with (a) than with (b), but differences between these treatments and (c) and differences in herbage P content in all treatments were not consistent over the years of the trial. Herbage crude ash content tended to increase and K and Na content decrease with increasing plant age. CP digestibility in green herbage and sun-dried hay was higher with (a) and (b) than with (c) and all treatments gave excellent silage.
