Title
CORN YIELD RESPONSE TO IRRIGATION, PLANT POPULATION AND NITROGEN IN A COOL, HUMID CLIMATE
D. M. BROWN Canadian Journal of Plant Science 1986. doi:10.4141/cjps86-063
Other claims from this paper (9)
- Intervention effect Irrigation did not affect corn development stages.
- Association Corn yield increases from irrigation scaled with midsummer water applied and dry-weather intensity.
- Intervention effect Higher plant density increased corn yields in four of five years.
- Intervention effect Extra nitrogen increased corn yields in 1982 and 1983.
- Intervention effect Extra nitrogen decreased corn yields in 1981.
- Intervention effect Extra nitrogen no differences corn yields in the other two years.
- Association Positive yield responses to extra nitrogen were usually greater with irrigation.
- Association Responses to extra nitrogen were greatest at high plant density and for longer season hybrids.
- Observation Corn harvest indices were exceptionally high in 1983.
