Abstract

The poultry manure and vertisols matter have potency for reclaiming a soil. The research objectives was to study the effect of poultry manure (PM) and vertisols matter (VM) on availability and leaching of macro nutrient in coastal sandy soil treated by rainfall simulation. A laboratory experiment was conducted with lesymeters to measure nutrient leaching. The factorial 4 × 4 treatment applied was arranged by randomized completely block design with three replications. The first factor was level of PM consisted of 0, 20, 40, and 60 Mg ha-1. The second one wasthe level of VM consisted of 0, 5, 10, and 15%. Variables observed were soil physical and chemical properties such as bulk density (BD), particle density (PD), porosity, pF 2.54, pF 4.2, available water capacity (AWC), permeability, cation exchange capacity (CEC), available macro nutrients (N, P, K, Ca, Mg, and S) by Morgan Wolf extraction, and the rate of macro nutrient leaching measuared by Spectrophotometry and Atomic Absorption Spectrophotometry. Result of the research showed that application of PM and VM in the sandy soil decreased soil PD and BD, increased soil porosity and AWC, decreased soil permeability, and slightly increased soil CEC. Application of PM and VM increased soil available nutrient in the sandy soil. Up to 60 Mg ha-1 dose PM increased soil available nutrient, while 10 to 15% dose, VM did not increased it. The rank of nutrient leaching from high to low by rain simulation was N-NO3 -> SO4 = > K+ > Ca2+. Leaching of K and N-NH4+ could be reduced by soil amendment. Combination of PM 60 Mg ha-1 and VM 10% was the best soil amendment for increasing nutrient availability and decreasing nutrient leaching in the sandy soil.Keywords: available nutrient, coastal sandy soil, leaching, poultry manure, vertisols matter

Abstract

Extension of jatropha planting on coastal sandy soil is an effort to look for an alternatif area to other soil types, this experiment is one of a series experiment aiming to classify jatropha based on their drought resistance, and to determine watering interval causing drought stress. The experiment was arranged using Split Plot Design with watering interval (once in 1, 3, 5, 7, and 9 day (s)) as main plot, and jatropha genotypes (IP-1A, IP-1M, IP-1P, IP-2A, IP-2M, IP-2P, Unggul Lokal (NTB), Gundul and Daun Kuning) as sub plot. The seeds of genotypes were planted in black polybag with coastal sandy soil media. The parameters observed were plant height, stem diameter, number of leaf, leaf width and plant dry weight, and the data collected were analyzed using Analysis of Variance, DMRT, Regrression and Cluster Analysis. The result showed that IP-1A, IP-2M, Gundul and IP-1M are the resistant genotypes, whereas Unggul Lokal, Daun Kuning, IP-2A and IP-2P are the susceptible genotypes. Once in one and three day (s) are optimum watering intervals, and once in nine days is a watering interval causing drought stress. Keywords : jatropha, drought, watering, coastal sandy soil

Abstract

ABSTRACTDevelopment of Jatropha, an important tropical biofuel crop, to coastal sandy soil is an urgent situation due to more limited of fossil fuel in one side, and high potency of coastal sandy land that has not been utilized yet. Tolerant and sensitive genotypes of Jatropha were treated with drought stress using watering interval, and their responds on the vegetative growth and yield were studied in this reasearch. Drought stress significantly decreased all vegetative growth parameters observed, except the number of branch. Different jatropha genotypes had different number of branch, number of leaf, root surface area, total of root length, root diameter, plant dry weight, shoot root ratio and light absorption. IP-1A genotype had the highest yield, i.e 33.54 g of dry seed plant-1 (equal to 0.15 ton ha-1), in the first year.Keywords: biofuel, sand, watering
