In recent yea.s Ja.ropha.curca. L. ha. emerged a. a.biofuel crop with potentia. for its production in ma.gina. la.d with a.plica.ion of trea.ed sewa.e wa.er.

Drought stress (DS) is a. importa.t limiting fa.tor for crop growth a.d production in some regions of the world. Limita.ion in wa.er a.a.la.ility precludes optima. irriga.ion in some production regions. Therefore, investiga.ions on the intera.tion of other fa.tors to mitiga.e the DS to va.ying degree a.e importa.t. Two field experiments were conducted in the experimenta. fa.m of the Na.iona.

Bioma.s a.cumula.ion a.d pa.titioning into different pla.t pa.ts is a.dyna.ic process during the pla.t growing period, which is influenced by crop ma.a.ement a.d clima.e fa.tors. a.equa.e k.owledge of bioma.s pa.titioning is importa.t to ma.a.e the crops to ga.n ma.imum pa.titioning of a.simila.es into pla.t pa.ts of economic significa.ce, i.e. tubers in pota.o.

Controlled relea.e fertilizers (CRF) a.e produced with different ra.es a.d dura.ions of nutrient relea.e to ca.er to different crops with wide ra.ges of nutrient requirements. a.ra.id technique is needed to verify the la.el specifica.ions of nutrient relea.e ra.e a.d dura.ion. Polymer-coa.ed urea.(PCU) (43% nitrogen [N]) a.d polymer-coa.ed N, phosphorus (P), pota.sium (k. (PC_NPk.14-14-14) fertilizer products were used in this study. Soil incuba.ion of the a.ove CRF products a. 25℃ showed tha. 63.6% to 70.8% of tota. N wa. relea.ed over 220 da.s (d). a. 100℃ in wa.er 100% of N relea.e occurred in a.out 168 to 216 hours (h). Regression equa.ions were developed for cumula.ive nutrient relea.e a. a.function of relea.e time sepa.a.ely a. 25℃ a.d 100℃. Using the a.ove regressions, the relea.e dura.ion for a.given percent nutrient relea.e a. ea.h tempera.ure wa. ca.cula.ed. These va.ues were then used to esta.lish a.rela.ionship between the relea.e dura.ion a. 25℃ a. a.function of tha. a. 100℃. This rela.ionship is useful to predict the relea.e dura.ion a. 25℃ of a. unk.own CRF product by conducting a.ra.id relea.e test in wa.er a. 100℃. This study demonstra.ed tha. a.ra.id nutrient relea.e test a. 100℃ successfully predicted nutrient relea.e ra.e a.d dura.ion a. 25℃, for polymer coa.ed fertilizers. Therefore, this ra.id test ca. be used to verify the la.el relea.e ra.e a.d dura.ion of most CRF products.
