EFFECT OF DIFFERENT MOISTURE REGIMES ON THE GROWTH AND QUALITY OF GLADIOLUS (Pages : 43 - 45)

An Experiment was conducted at the floriculture field of Horticulture Research Centre, BARI, Joydebpur during 2003-2004 and 2004-05 to find out the irrigation requirement and a proper irrigation schedule of gladiolus (var. GL-001). Five irrigation schedules were considered viz.; I0 : no irrigation, I1 : plant emergence + spike initiation, I2 : 4 leaves + spike initiation, I3 : plant emergence + 4 leaves + spike initiation and I4 : plant emergence + 4 leaves + spike initiation + flower initiation. Irrigation had significant influence on the increase number of spike of gladiolus over control (non irrigated). On the basis of two years result the highest spike yield of gladiolus was recorded with three irrigations applied each at sprouting, 4 leaves and spike initiation stage which was statistically identical to four irrigations each at plant emergence, 4 leaves, spike initiation and flower initiation stage. The lowest spike yield of gladiolus was obtained from control treatment (no irrigation). The highest total water expense (TWE) bearing was in I4 and the lowest in I0. The highest water expense efficiency was obtained with non-irrigated (control) treatment (I0). Soil water depletion was decreased with increased irrigation water. Download
