Description The vegetative and reproductive growth of six groundnut genotypes (Arachis hypogaea L.) in two photoperiods were studied in a field experiment. Normal daylength was 11–13 h and long-day conditions (15–16 h) were provided by extending the day with tungsten-filament bulbs. Yield differences between the photoperiodd treatments were largely explained by changes in crop growth rate, partitioning, and the length of the effective pod-filling period. Long days resulted in increased crop growth rates but generally decreased partitioning and the duration of the crops' effective pod-filling phase. However, it was dependent on the genotype which of the yield-determining processes had been more influenced by day-length conditions. In some cases, partitioning contributed most to yield ifference; in others, the duration of the effective pod-filling phase contributed most.
