Abstract

Coastal land area are potential as a source of fulfillment of food. Environmental conditions in the coastal area generally have a high temperature, saline, sandy soil, strongs winds, and high evaporation. One of the coastal land reclamation method is to use the presence of trees combined with the type of legume crops through agroforestry patterns. This study aims to determine soybean varieties adaptive to the beach area. Experiments using Completely Randomized Design Group. Varieties of soybean in the test consists of four varieties: derings 1 (drought-tolerant), dena 2 (shade tolerant), deram 1 (saline soil tolerant) and local (control). The seeds of each variety were planted in plots measuring 4 x 3 m of 7 replicates. Character of nyamplung plant observed were height and diameter and character of soybean plants observed were: plant height and root length (cm) were taken destructif sampling as many as 10 samples (at 60 days old), number of branches, number of pods, seed weight per plant, seed weight, based weight of 100 grains, and heavy yields. The data were analyzed by using analysis of variance. The results showed that soybean varieties that give the lowest to the highest production is dena (2.37 ton.ha-1), thunder (1.31 ton.ha-1), local (1.13 ton.ha-1) and the ring (0.81 ton.ha-1).Key words : Agroforestry, coastal area, soybean, varieties

Abstract

Land management in agroforestry systems requires species selection and proper silviculture. Selection of species and silvicultural treatments aimed at maintaining competition in obtaining a light, water and nutrients. Farmers choose the species based on the economical factor. This study aims to determine the composition of plant species in dry land agroforestry in Menoreh Hill, Kulon Progo District. Research done by survey method. Plot observation was divided into three level of light intensity: : a) early agroforestry (light intensity >50%), b) middle agroforestry, (light intensity 30-50%), c) further agroforestry (light intensity <30%). Four planting plots were made as repetition, so that there were 12 plots observation. Observations and measurements of vegetation are done with census (100%). The Result show five important value index in early Agroforestry,: sengon (77.84), coconut (50.04), and cacao (25.47), tree density was 482 trees/hectare and basal area 5.48 m2/ha, in middle agroforestry were: sengon (88.15), mahogany (49.51), and clove (45.03), with tree density was 595 trees/ha, and basal area was 6.70 m2/ha, further agroforestry were: clove (72.37%), sengon (50.61), and coconut (37.02), tree density was 650 trees/ha, basal area was 6.78 m2/ha.
