ESTABLISH DROUGHT TOLERANT PLANTS BY DIRECT SEEDING
PROGRESS IS REPORTED ON RESEARCH BEING CONDUCTED BY THE UNIVERSITY OF CALIFORNIA, AT DAVIS, CONSISTING OF ESTABLISHING DROUGHT-TOLERANT PLANTS BY DIRECT SEEDING. PLANT SPECIES AND ECOTYPES WITHIN SPECIES ARE BEING EVALUATED AND SELECTED FOR DROUGHT-TOLERANCE, AGGRESSIVENESS, RESISTANCE TO INSECTS AND DISEASES, BEAUTY AND THE ABILITY TO ACCOMPLISH THE DESIRED FUNCTIONAL PURPOSE. SEEDING TECHNIQUES ARE BEING DEVELOPED WHICH CONSIDER MAXIMUM UTILIZATION OF THE PLANT'S INHERENT SEED GERMINATABILITY, NATURAL SOIL MOISTURE, SUITABLE SOIL TEMPERATURE, FERTILIZER PLACEMENT AND WEEK CONTROL. THE GOAL IS TO OBTAIN ATTRACTIVE AND FUNCTIONAL ROADSIDE PLANTINGS WHICH ARE ABLE TO SURVIVE WITH MINIMUM MAINTENANCE AND WITH LITTLE OR NO IRRIGATION. TRIALS TO DATA INDICATE THIS PLANTING TECHNIQUE CAN BE APPLIED ON ROADSIDES THROUGHOUT THE STATE, USING INDIGENOUS PLANT MATERIAL OR PLANTS GROWING UNDER CLIMATIC CONDITIONS SIMILAR TO THAT SPECIFIC AREA. /AUTHOR/
