    Prosedures en probleme by die gebruik van die PUTU9–87 gewasgroeisimulasiemodel vir koring onder besproeiing in die Vanderkloof-Staatswaterskema

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die doel van hierdie ondersoek was om die PUTU9–87 gewasgroeisimulasiemodelte kalibreer om koringop-brengste en die grondwaterinhoud op 'n bevredlgende wyse in die Vanderkloof-Staatswaterskema te voor- spel, gegewe beperkte eksperimentele data. Opbrengste wat met PUTU voorspel is, word vergelyk met eksperimentele...
