Response surfaces of growth and yield of wheat
(Lincoln College, University of Canterbury, 1979)
In the 1976-77 and 1977-78 seasons four field experiments using a three factor central composite second order design in incomplete blocks were conducted to quantify the responses of autumn-sown wheats established at five ...
Components of grain yield in wheat
(Lincoln College, University of Canterbury, 1977)
Between 1972 and 1976 a series of field experiments were conducted to investigate the factors limiting grain yield in wheat (Triticum aestivum L). Spike population restricted yield when it was below about 500 spikes/m² ...
