Effect of Paranet Shade on the Four Green Bean in Jatikerto Dry Land Indonesia

摘要

Background and Objective: The increased frequency of drought causes low yield of green beans in dry land. Therefore, the selection of tolerant varieties and the use of paranet as a shade can provide the best solution related to the problems. The aim of this study was to investigate the effect of paranet shade on the yield of four Green Beans in dry land of Indonesia. Materials and Methods: The study was conducted at Techno Park Universities Brawijaya Malang Indonesia and planting was carried out in September to November, 2016. The treatments of variety and paranet shade were arranged in a split-plot design with 3 replications. Variety was placed as the main plot and percentage of paranet shade as sub-plot. F-test at 5% is used to determine the effect of treatments, while differences between treatments were referred to least significant different (LSD) value at 5%. Results: The highest yield was obtained in the treatment without shade for all varieties, including total dry weight of plants, number of pods/plant, weight of seeds/plant, yield of seeds/hectare and reception of radiation energy. Provision of shade causes a decrease in seed yield /hectare by an average of 46.37, 24.16, 46.85 and 37.14%, respectively for the varieties of Murai, Sriti, Kenari and Perkutut compared to the treatment without shade. However, the provision of shade led to an increase in leaf size by 10.50, 18.21 and 19.38%, respectively for the treatment of 20, 40 and 60% shade than without shade. Conclusion: In the treatment without shade, total dry weight of plants, number of pods/plant, weight of seeds/plant and yield of seeds/hectare produced is higher than shade treatment.
