In maize grain and silage trials at Newe Ya'ar Experiment Station in 1984-85 max. grain yields were > 15 t/ha. N application of > 275 kg/ha did not increase grain yields. Irrigation frequency (1-6 days) did not alter yield of P3323, but decreased yield of hybrid JX180. Significant regression coeff. were found between both whole plant or ear N accumulation and total DM in ears or the whole plant. Max. grain and total DM yield were achieved at 74 000-78 000 plants/ha.
