Abstract

Difference in Harvest Age Against the Results and Quality of Seedlings of Beans
(Phaseolus vulgaris L.)

This study aims to determine the effect of seed age on the yield and quality of
beans. This research is a one factor research with three different age of harvest
treatments are: harvest before physiological maturity 24 days after flower blooms,
harvest at physiological maturity is 27 days after flower blooms, and harvest after
physiological maturity is 30 days after flower bloom. This study used a randomized
block design (RBD) with 9 replications. The observed variables included: the
development of the seed wet weight, seed oven dry weight, seed moisture content, pod
and seed character, percentage of good seed, weight of 1000 seed grains, seed
germination, and seed growth simultaneity. The results showed that the pod harvest
time for the best seeds was carried out at the age of 27 days after the flowers bloomed.
At that time the highest dry weight of the seeds and pods had changed color from green
to yellowish green. At that time the seeds also showed maximum quality
characteristics, such as the percentage of good seeds (87.22%) and the weight of 1000
seeds (91.34 g). Physiological characteristics of seed quality such as seed germination
capacity of 99.78% and 88.78% simultaneity of seed growth were also obtained at the
time of pod harvest at 27 days after flower blooms.
