Tiller turnover differences in four commercial varieties sown under contrasting environments were followed from sowing up to harvest. Three different phases were recognized from the patterns observed. Tiller production was the dominant feature of the first phase which culminates in a peak tiller number stage. During the second phase, tiller d eath was predominant and leads to the achievement of a stable population (third phase) which survives up to harvest. Environmental effects were seen through differences in rates and duration of tiller production in the initial phase. Peak tiller number stage was closely related to the number of millable stalks observed at harvest. Higher tiller production irrespective of environmental conditions or variety led to higher number of stalks at harvest inspite of differences in tiller mortality. Changes within and between stalk populations are discussed in relation to a crop phasing strategy aimed at yield increases at harvest. | |
