MODEL MATEMATIKA PERTUMBUHAN JUMLAH ANAKAN DAN TINGGI TANAMAN PADI YANG DITANAM DENGAN METODE SRI
Abstract: The food requirement
in Indonesia is highly dependent on rice and its requirement is increasing. On
the other hand, the avalability of natural resource especially land and water
are getting more limited. Consequently,there is a need to increase rice
production with efficient resources. On the other hand, there is a necessity to
apply sustainable agriculture. SRI (System of Rice Intensification) method was
developed to deal with the problems. In the field, the SRI method still shows a
wide variation of yields, therefore researches are necessary to reveal the phenomena
behind this method. This paper aims to develop mathematical models of rice
tillers and plant height of rice growth as well as to compare the growth of
rice plants at several locations and treatments. Mathematical models developed
were the rice tillers’ growth model which follow the exponential polynomial
function order 2 and the crop heights model which follow the monomolekuler
function. The number of seedlings from one seed planted in SRI would result
more tillers than conventional crops after more than 30 days after planting.
Conventional crop height was relatively higher than that of SRI because close
spacing and inorganic fertilizers trigger vegetative growth.
