Variability in yield of four grain legume species in a subhumid temperate environment. I. Yields and harvest index
(Cambridge University Press, 2004-02)
In 1998/99 and 1999/2000, field trials were conducted to try to explain why grain legume yields and harvest index are more variable than many other crops. Treatments involved varying plant populations and sowing depths and ...
Variability in yield of four grain legume species in a subhumid temperate environment. II. Yield components
(Cambridge University Press, 2004-02)
The effects of plant population (one-tenth of the optimum to four times the optimum populations in 1998/99 and 10–400 plants/m² in 1999/2000) and sowing depth (2, 5 and 10 cm) on yield and yield components of four grain-legumes ...
