Abstract: BARROT, IRENEO. Don Severino Agricultural College, Indang, Cavite, April 1992. EFFECT OF POPULATION DENSITY ON THE GROWTH AND YIELD OF FIVE COTTON VARIETIES. Major Adviser: DR. VICENTE G. LONTOC. The study was conducted to determine the effect of population density on the growth and yield of five varieties of cotton; to identify the most appropriate population density that is most suitable to cotton production; and identify the most suitable variety of cotton that will give the highest yield. Split-plot in Randomized Complete Block Design was used in this study with five varieties of cotton as the main treatments and three population density as the sub-treatments. Results showed that population density merely affects the growth and yield of cotton. Variety 2 (ACC-455) under population density 3 (26,666 plants per hectare) gave a better results in terms of leaf area index, number of square formed at flowering, number of bolls produced at maturity, fresh and dry weight of plant, number of harvested bolls , and seed cotton yield per hectare. On the other hand, the tallest plant, number of branches and number of leaves was observed in higher population density in all varieties of cotton used. Results revealed that higher yield of cotton can be obtained if they are planted at lower population density (26,666 plants per hectare). This might be due to lesser competition between plant for light, water and nutrients.

BARROT, IRENEO. Don Severino Agricultural College, Indang, Cavite, April 1992. EFFECT OF POPULATION DENSITY ON THE GROWTH AND YIELD OF FIVE COTTON VARIETIES. Major Adviser: DR. VICENTE G. LONTOC.

The study was conducted to determine the effect of population density on the growth and yield of five varieties of cotton; to identify the most appropriate population density that is most suitable to cotton production; and identify the most suitable variety of cotton that will give the highest yield.

Split-plot in Randomized Complete Block Design was used in this study with five varieties of cotton as the main treatments and three population density as the sub-treatments.

Results showed that population density merely affects the growth and yield of cotton. Variety 2 (ACC-455) under population density 3 (26,666 plants per hectare) gave a better results in terms of leaf area index, number of square formed at flowering, number of bolls produced at maturity, fresh and dry weight of plant, number of harvested bolls , and seed cotton yield per hectare.

On the other hand, the tallest plant, number of branches and number of leaves was observed in higher population density in all varieties of cotton used. Results revealed that higher yield of cotton can be obtained if they are planted at lower population density (26,666 plants per hectare). This might be due to lesser competition between plant for light, water and nutrients.
