2018 ASHS Annual Conference

This experiment was carried out to investigate the effect of number of lateral shoots on growth and yield according to the external weather conditions during the growing stage. The test group was divided into zero, one, two and three leaves of lateral shoots based on one leaf on main branch from March 31 to November 15, 2014 for 36 weeks. As a result of this experiment, the total LAI difference between zero leaf and three leaves was about three times. The plant height was the largest at 286.86cm on zero leaf, and the smallest at 259.14cm on two leaves. In the period 1, the average fruit weight was 258.97g, 260.65g, 271.86g and 255.43g, respectively. However, as the growth progressed, it decreased to 110.73g, 104.21g, 95.1g and 72.04g, respectively, in Period 5, reversing to 148.24g 156.44g, 176.76g and 183.39g. The total production of zero leaf was 58.8kg, the smallest. And the largest yield 73.6kg of two leaves. In conclusion, by the fact that total yield increased to two leaves from zero leaf but decreased over two leaves, two leaves are considered to be the best number of lateral shoots in winter-plant cultivation of paprika.
