Abstract

A study that was aimed to elucidate roles of Gliricidia sepium and Tithonia diversifolia prunings and their extracted humic and fulvic acids on improving phosphorus availability and decreasing aluminum concentration in an Ultisol was conducted in a glasshouse. Thirteen treatments consisting of two prunings, six rates of pruning application (5, 7.5, 10, 20, 40 and 80 t/ha) and one control (no added prunings) were arranged in a randomized block design with four replicates. Each mixture of prunings and soil was placed in a pot containing 8 kg of soil and maize of Srikandi cultivar was grown on it for 45 days. At harvest, soil pH, P content and aluminium concentration were measured. Results of the glasshouse experiment showed that application of Gliricidia and Tithonia prunings significantly increased soil pH, reduced Alo concentration, increased Alp content, increased P availability, and increased P taken up by maize grown for 45 days. The optimum rate of both Gliricidia and Tithonia pruning should be 40 t/ha. However, at the same rate, optimum production gained by Tithonia would be higher than that of Gliricidia.

Abstract

The purpose of this study was to evaluate the socio-economic impact of land degradation and the role of watershed management in the development of agroforestry to support food safety and security. This study used descriptive analytical method that was based on the observations, interviews, and literature survey. Thirty respondents were randomly selected for this study. The results showed that the socio-economic impact of land degradation was the decline production of cassava for the last four years. Watershed management played an important role in the development of agroforestry to support food security. Agroforestry-based soil conservation did not run optimally due to a number of obstacles in its development. The development constraints were large area of critical lands and lack of technology transfer on watershed management. Policies needed in the development of agroforestry-based soil conservation to support of food safety and security are improvement of formal and non–formal educations, adoption of watershed management technology, and empowerment of farmers for agroforestry development.

Abstract

The cultivation of purple long yard bean which tolerance to drought stress and have high productivity can improve farming in arid area. The purpose of this study was to evaluate the mechanism of the tolerance purple long yard beans to drought stress based on morphologic characters, to get the hypothesis method of tolerance and to obtain tolerance cultivars to the drought stress. Eight cultivars of purple long yard beans, i.e. UBPHU1-41, UBPHU1-130, UBPU3-153, UBPU1-202, UBPU2-222, UBPU1-365, Brawijaya 4 and Bagong 2, were tested in two environmental conditions, 100% field capacity and 50% field capacity. The results showed that drought stress in purple long yard bean affected all morphological characters observed, except for root length and flowering time. Estimation of tolerance to drought stress using the Principles Component Analysis (PCA) showed that the shoot fresh weight could be an indicator of purple pod bean tolerance to drought stress. However, the test using Stress Susceptibility Index (SSI) was not able to classify the purple long yard bean tolerance to drought stress. The results of analysis using PCA followed by discriminant analysis and clustering dendrogram showed that the UBPU1-41, UBPU1-130, UBPU2-222, UBPU1-365, UB4 and Bagong 2 cultivars were medium cultivars that are tolerant to drought stress. Therefore, they can be planted in semiarid regions.

Abstract

A study that was aimed to determine the effect of the use of organic manure and azolla on methane emission on paddy field of organic systems was conducted on paddy fields in the Gempol Village, Sambirejo District of Sragen Regency, Indonesia. The experimental design performed for this study was a completely randomized block design consisting of three factors; the factor I was rice cultivars (Mira-1; Mentik Wangi; Merah Putih); factor II was dose of organic manure (0 t/ha and 10 t/ha) and factor III was Azolla inoculums dose (0 t/ha and 2 t/ha). Gas sampling was conducted 3 times in one growing season when the rice plants reached ages of 38, 66 and 90 days after planting. The results showed that there was no correlation between the uses of organic fertilizers for rice production on methane emission. The increase of methane emission was very much influenced by the redox potential. Methane emission from Mira-1 field was higher than that from Mentik Wangi and Merah Putih fields. Emission of methane gas from Mira-1 field ranged from -509.82 to 791.34 kg CH4/ha; that from Wangi ranged from -756.77 to d 547.50 kg CH4/ha and that from Merah Putih ranged from -399.63 to 459.94 kg CH4/ha. Application of 10 t organic manure /ha and 2 t azolla/ha in Mentik Wangi reduced methane emissions with a high rice production compared to Merah Putih and Mira-1.

Abstract

In support of healthy agriculture development to improve farmer’s prosperity status, soil remediation and land conservation efforts maybe relied on the use of biomass of local vegetation. Results of field exploration conducted at Brantas Watershed of East Java indicated that there were at least 154 species of undergrowth scrubs, 47 species of agriculture-plantation crops, and 59 species of road shelter trees. The native undergrowth vegetations had undergone enormous seasonal variations. Biomass of predominance vegetations, e.g. Psophocarpus tetragonolobus, Phaseolus lunatus, Flemingia, Mimosa somian, Acacia villosa, Cassia mimosoides, Mucuna could potentially be used as organic matter sources to improve availability of nitrogen and phosphorus in soils. The amount of nitrogen and phosphorus contributed of the plant biomass significantly correlated with quality of the biomass.

Abstract

Low productivity of food crops on marginal dry lands of South Malang, East Java occurs due to low levels of soil fertility in the region due to low soil organic matter content and low content of available P. The purpose of this study was to evaluate the effect of the combination of biochar and plant litter on chemical properties of a degraded soil of South Malang, and P uptake by maize. The treatments tested in this study was a combination of types of biochar (sugarcane litter biochar and maize litter biochar), and the type of fresh litter (sugarcane and maize). Biochar doses applied were 0, 20 and 40 t biochar / ha, whereas the doses of fresh litters applied were 0, 40, and 80 t litter / ha. Three maize seed of BISI 2 variety was grown in each pot (treatment) for 49 days. Nine treatments were arranged in a completely randomized design with three replications. The results showed that application of litter and biochar tended to lower pH, CEC, exchangeable Ca, and total P the soil studied. The interaction of litter and biochar did not significantly increase P availability in the soil. However, application of litter and biochar also increased P uptake by maize. The best treatment for maximum increase of P availability and uptake of P was application 80 t sugarcane fresh litter / ha and 40 t maize litter biochar / ha.
