ROSARDA, MARK ARIEL A., ATERRADO, GIA ANGELICA B., and PERLADO, MELFOMINIE P. Effects of Planting Distance on the Growth and Yield of Gotu kola (Centella asiatica). A Research Study (General Science Curriculum). Science High School, College of Education, Cavite State University, Indang, Cavite, April 2011. Adviser: Dr. Analita dM Magsino.

This study entitled “The effects of planting distance on the growth and yield of gotu-kola(Centella asiatica)” was conducted at the Culinary Herbs, Aromatics and Medicinals, Project of the Department of Crop Science, CVSU-CAFENR from November 2010 to January 2011. The main objective of the study was to determine the growth and yield performance of gotu kola (Centella asiatica) in different planting distances. The specific objectives were to determine the effects of planting distance on the growth and yield of gotu kola; to compare the growth and yield differences of gotu kola raised in different planting distances, and to identify the planting distance for the production of gotu kola (Centella asiatica). The different planting distances include Treatment 1 - 30 cm between rows by 30 cm between plants, Treatment 2- 40 cm between rows by 30 cm between plants, Treatment 3 - 50 cm between rows by 30 cm between plants, and Treatment 4 - 60 cm between rows by 30 cm between plants.

The experiment was arranged following RCBD (Randomized Complete Block Design) with four planting distances as treatments, three blocks or replications, and six plants per replication. Canopy diameter, number of leaves, number of shoots, shoot yield, and percentage survival were the parameters used to determine the effects of gotu-kola as affected by different planting distances.


Canopy diameter was not significantly affected by planting distance. It was observed that the widest canopy diameter was consistently exhibited in Treatment 1 and the narrowest canopy diameter was inconsistently exhibited.

Number of leaves was not also significantly affected by planting distance. It was observed that the highest leaf production was consistently exhibited in Treatment 1 and the lowest leaf count was consistently exhibited in Treatment 4.

Number of shoots was not also significantly affected by planting distance. It was observed that the most number of shoots was exhibited in Treatment 1 and the least number of shoots was consistently exhibited in Treatment 4.
