The fate of fertilizer nitrogen applied to the paddy field and its absorption by rice plant part 7 relationships between the absorption of nitrogen by the rice plants and the growth of the plants



The fate of fertilizer nitrogen applied to the paddy field and its absorption by rice plant part 7 relationships between the absorption of nitrogen by the rice plants and the growth of the plants



Japanese Journal of Crop Science 45(2): 220-225



The rate of N absorption was greatest just before the neck mode differentiation stage throughout all the growth stages. The greatest rate of N absorption at this stage was positively correlated to the length of culms, the sum of lengths of lower 3 internodes, the sum of lengths of upper 3 leaf blades (excepting those of the plots of N topdressing) and the number of spikelets per panicle (except those of the plots of no basal N, N topdressing at the neck node differentiation stage and at the stage of reduction division), respectively. The amount of plant N per unit area at the early stage of spikelet differentiation was positively correlated to the number of panicles per unit area. The amount of N in plant per unit area at the ear mergence was positively correlated to the number of spikelets per unit area. To obtain optimum growth, the rate of N absorption by rice plants must be decreased just before neck node differentiation stage and be increased at the other growth stages. Early transplanting and high plant density improved N absorption and increased yield per unit area.
