A study of grain yield and nitrogen content in different shoots of wheat
(Lincoln College, University of Canterbury, 1984)
Three field experiments were conducted on different high fertility soils during the years 1979-80 and 1980-81 to investigate factors controlling grain yield and nitrogen content in wheat (Triticum aestivum L.). Autumn-sown ...
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 ...
