ABSTRACT
Increasing the productivity of lowland rice can be done by offering P
fertilizer using the System of Rice Intensification (SRI). Optimal growth in plants
is determined by the availability of Phosphorus (P) in the soil medium. The
available P nutrients were increased by P fertilization. This study aims to
determine the interaction effect of multiple doses and timing of application of P
fertilizer, the main effect of each and to obtain the best treatment for the growth
and yield of rice (Oryza sativa L.) with the modified SRI method. The study was
conducted using a factorial completely randomized design (CRD) consisting of 2
factors, namely the application of phosphorus fertilizer (P) with three levels,
namely (54, 81, 108) kg P2O5.ha-1 and the time of application of P fertilizer with
three levels, namely at planting time (PT), PT and 30 days after planting (DAP),
PT, 30 DAP and 60 DAP. Parameters observed were plant height, maximum
number of tillers, number of productive tillers, plant dry weight, root crown ratio,
panicle exit age, harvest age, number of pithy grain per panicle, percentage of
pithy grain per panicle, 1000 grain weight of pithy grain, grain weight. milled
dryness per clump and harvest index. The interaction treatment of phosphorus
fertilizer dose and time of administration did not affect all the parameters of the
observation. The application of phosphorus fertilizer had an effect on plant height,
maximum tiller number, number of productive tillers, number of pithy grain per
panicle, percentage of pithy grain per panicle, weight of milled dry grain per
clump and harvest index. The time of applying phosphorus fertilizer had an effect
on plant height, weight of milled dry grain per clump and harvest index. The
combination treatment of fertilizer dose of P 81 kg P2O5.ha-1 and time of
application was three times better than other combinations. The dose of P fertilizer
at 81 kg P2O5.ha-1 was better than the dose of 54 kg P2O5.ha-1 and 108 kg P2O5.ha-
1. The time of administration was three times better than the time of
administration once and the time of administration was twice on plant height. The
time of giving was twice better than the time of giving once and the time of giving
three times on the weight of milled dry grain per clump and harvest index.
