GROWTH AND YIELD OF 3 VARIETIES OF WHEAT WITH PARTICULAR REFERENCE TO INFLUENCE OF UNPRODUCTIVE TILLERS

An experiment was done to see if three varieties of wheat (Jufy I, Yeoman and Cappelle) of widely different tillering propensities differed in their response to early spring application of nitrogen; and, concurrently and conjointly, to assess the effects of unproductive tillers on the growth of productive shoots. None of the varieties responded to the higher of two levels of nitrogen. The presence of a large number of unproductive tillers appeared to have only a transitory effect on the growth of productive shoots; the latter were able to grow rapidly after the death of tillers and caught up with productive shoots which had been subjected to much less inter-tiller competition. © 1969, Cambridge University Press.
