Growth and production of seven soybean varieties (Glycine max (L.) Merrill) in a coastal area

Abstract

An experiment was conducted in Barombong, Makassar City, to determine the growth and production of several soybean varieties on coastal land. The research was an experiment designed by a randomized block design with seven soybean varieties as treatments, namely Ijen, Wilis, Anjasmoro, Sinabung, Burangrang, Tanggamus, and Kaba. Each treatment was repeated four times, making a total of 28 experimental units. Results showed that all varieties could adapt to the coastal area. However, Anjasmoro provided the best growth and production based on variables of plant height (58.50 cm), the weight of 100 seeds (14.93 g), seeds weight per plot (447.65 g) and seed production per hectare (1.70 tons ha-1). Ijen variety only gave the highest value on the number of leaves (20 strands) and the earliest 50% flowering age, (33.5 days). Kaba variety only gave the highest value on productive branches (2.75 branches) and the earliest 50% flowering age (33.5 days). Sinabung variety only gave the highest value on the number of pods per plant (30.9 pods) and the lowest percentage of empty pods (17.33%). Burangrang variety gave the earliest harvesting time at 85.5 days.
