Abstract

This study investigated the effect of different leaching rates on the downward movement of zinc applied, as fertilizer, on the surface of a sandy soil. The experiment was conducted in polyethylene bags filled to 30 cm depth with sandy soil. A zinc supply of 15.3 10-3 cmolc kg-1 was applied to the soil surface as a solution of zinc sulfate. Three leaching rates were tested: 31 mm, 208 mm and 497 mm. Results showed the absence of zinc in the leachate for all leaching rates. Within the soil profile, the highest content on exchangeable zinc (15.3 10-3 cmolc kg-1) was recorded in the top soil layer (0-10cm) for all leaching rates. In the middle (10-20 cm) and in the lower (20-30 cm) layers, the exchangeable zinc content remained similar to that recorded before leaching (0.76 10-3 cmolc kg-1). The percentage of the cation exchange capacity occupied by zinc in the top soil layer increased after leaching. It averaged 0.35% for all leaching rates while it remained similar to that recorded before leaching (0.03%) for the middle and the lower layers. This increase was linked to the adsorption saturations sites particularly released by manganese, potassium, calcium and ammonium after their downward movement.

Abstract

The research was carried out in the Laboratory of Soil Science and greenhouse Agriculture Faculty, Jenderal Soedirman University. This experiment was aimed at studying the effects of fertilizer adhesive levels and fertilizer granule size on water penetration, water, and soil chemical properties. The research was laid out according to Completely Randomized Design (CRD), consisting of 2 factors i.e. fertilizer granule size (2 sizes) and fertilizer adhesive (5 levels). There were 10 types of NZEO-SR fertilizers tested with 3 replications. The fertilizers were tested in water and soil media, totaling 60 experimental units. The results showed that NZEO-SR fertilizer having a diameter of 2.5 - 3.0 mm in combination with 3% (w/w) fertilizer adhesive had the highest ability to resist water penetration. Levels of fertilizer adhesive material gave significant effects on pH (H2O), electrical conductivity (EC) and water-soluble N. Diameter of fertilizer had no effect on all the variables studied, except for water-soluble N. Levels of fertilizer adhesive significantly affected the pH (H2O) and total soil N, but did not show significant effects on the EC and soil available N. The diameter of fertilizer had no effect on all soil chemical variables.

Abstract

Agriculture and irrigation policies in the tidal wetlands are often too general, thus at the level of farm units they are often inaccurate in term of quality and quantity. The research purpose was to analyze the groundwater levels and to determine the effect of groundwater levels in relation to some soil chemical characters in tidal wetlands P17-5S Mulyasari village Delta Telang II Banyuasin.  Indicators of potential land can be analyzed from parameters of variability of soil acidity, Al and Fe content, organic matter and phosphorus and nitrogen status of the soil. Managed limited area was the smallest unit of water management (tertiary plots). The decision was taken based on the dominant values of the hydro-physical and chemical characters. Input criteria design involved the nature of the soil, land use, and hydrology. The field study and analysis showed dominance in soil physical variability. Around 50% of hydraulic conductivity was classified rapid soil with soil acidity is relatively high, moderate nitrogen, low phosphorus, and moderate potassium. Based on these conditions, cropping pattern applied was rice-corn, rice-water melon, soil fertility can be improved through fertilization of N and P; increasing water gate in the tertiary plots, and the water management aimed to controlled drainage

Abstract

The research aimed to know the kind of legume cover crop which more suitable to be cultivated especially in area of Natar, South Lampung and to know the efficiency of N supply. It used a single Completely Randomized Block Design (CRBD) consisted of 4 treatments (several kinds of debris), covering: kacang benguk (Mucuna cochinchinensis), kacang ruji (Pueraria javanica), and oil-palm empty bunch compared to one which no debris added (control). Data analyzed by regression, F test (α 5%; or Kruskal-Wallis), DMR test (α 5%; or Mood Median) and correlation test. Result showed that Pueraria javanica (kacang ruji) was more suitable to be cultivated. Regression showed that management of empty bunch tend to enhance the ratio of NH4+/N-mineral as indicator of N supply efficiency, while the management of Pueraria javanica tend to decrease the ratio of NH4+/N-mineral. The degradation of soil NO3- concentration in the treatment of empty bunch was followed by the degradation of soil nitrification potential and the enhancement of heterotrofic bacteria. The enhancement of soil nitrification potential in the Pueraria javanica and Mucuna cochinchinensis management was followed by the degradation of soil pH.

Abstract

Application of Zn, beside as an essential nutrient for plants, is known to increase the resistance of plants during drought condition. The purpose of the research was to study the effect of ZnSO4 application on root and leaf character of tomato plants in drought conditions. Research was arranged in factorial randomized completely block design. The treatment consists of ZnSO4 application methods (soil and foliar), ZnS04 dosage (0, 40 and 60 mg Zn kg-1 and cultivars ('Permata’ F1 and 'Tyrana’ F1). Watering intervals of every two and eight days were applied, representing non-stress and drought stress conditions during the growth period of the plant. The results showed that the all response of character roots and leaves of the tomato did not show interaction among the three factors. Root biomass, root length and root surface area of tomato plants depend on the method of application and ZnSO4 dosage. Soil application increased root biomass and root surface area. Root biomass of ‘Permata’ and ‘Tyrana’ showed differences in responses to dosage of ZnSO4. Leaf area responses in both cultivars ‘Permata’ and ‘Tyrana’ showed the same pattern of the ZnSO4 dosage. Response of leaf area ratio at each stage of tomato growth on ZnSO4 application was different.

Abstract

The problem of low soybean yield on Alfisol is low soil fertility. The availability of P is often a constraint because the P element on the Alfisol soil is strongly bound by Al and Fe elements. Efforts to increase the availability of P element in Alfisols can be done by ameliorant of zeolite and organic fertilizer. This study objective was determined of zeolite and organic fertilizer in increasing of available P and soybean yield on Alfisols. A field experiment was conducted using Randomized Block Design consisting of two factors: a dose of zeolite (0 ton ha-1, 2.5 tons ha-1, and 5 ton ha-1), and organic fertilizer (no organic fertilizer, quail, and cow manure 5 ton ha-1 respectively). The results showed that zeolite 5 ton ha-1 is the highest effect on the increasing of available P, pH, organic matter, and saturation base as big as 5.19, 5.21, 24.03, and 21.55 respectively, while cow manure is improved to organic matter and saturation base 26.17, and 21.38% respectively.The combination of zeolite and cow manure 5 ton ha-1 gave the highest yield on the number of pods (101 pods plants-1), and the 1000 seeds weight is 153 g.

Abstract

Banana stem water content is 90%. Therefore, it is potential as an alternative for planting media in limited agriculture lands due to their function changes. The aim of the research is to obtain information on cultivation technology and how long water content in banana stem is available for plant. This research employed the randomized block design- split plot with two treatment factors. The first factor was banana stem durations after harvest (0, 2, and four weeks) and the second one was vegetable crops, namely: kangkungs and mustard greens. Based on the treatment level, there were six combinations, and each was replicated 4 times. The research variables were height, number of leaves, chlorophyll content, nitrogen tissue, leaf area index, specific leaf area, unit price of leaves, growth rate, biomass (dry weight of the plant), length of root, and fresh weight of the plant. The result of the research shows that all treatments applied to banana stems had no effect on all variables tested. Banana stems could provide water to Ipomoea reptans Poir for the duration of 37 days after planting, and to mustards greens for the duration of 32 days after planting. Above the stated duration, the plant died due to water excess. Thus, banana stems had the potential to provide water for plants from planting to harvest, and the plants planted did not require additional watering.

The objectives of this study were to know the successful of shoots growth with seeding treatment and production quality due to fertilizing package for seedless watermelon with the variety of Riendow F1. The experiment was conducted in dry season at upland areas in Palangkaraya. The experimental design for seeding randomized block design (RBD) 3x3 with treatment consisting of a control (G0), cracking seed by hitting (G1), cracking seed using pincette (G2). The experiment of fertilizing package at productive phase used of fertilizer used RBD 4x3. The treatment consisted of several packages of fertilizer, namely: without fertilization (P0), low fertilizer package (P1), medium fertilizer package (P2), and high fertilizer package (P3). Before the experiment, soil analysis was first conducted to determine land suitability classes. The results showed that the study site area has marginal suitability class with limiting factor involving rooting condition (S3rc). The highest germination was obtained in the cracking treatment compared to control, otherwise, the rate of death seeds for control was lower than cracking treatment although it is not significantly different according to statistics. For the parameter of fruit perimeter, it indicates that treatment of high fertilizing package was significantly different from the control, respectively, 64.25 cm and 53.96 cm. It also includes the weight of fruit, respectively, 4.05 kg and 2.80 kg. For the quality of watermelon, it showed that fertilizing packages at productive phase is significantly different from controls. The sweetness level at the medium fertilizing package (P2) has the highest level of 11.73oBrix, followed by the high fertilizing package (P3), 11.00oBrix, low fertilizing package (P1), 9.92oBrix and the lowest for control, 8.98oBrix. Application of medium fertilizing package at productive phase can then produce the highest quality level of watermelon.

Abstract

Sustainability of paddy field becomes the main concern as the media of biomass production, thus it is needed a data and information about land characteristics to find out its degradation. Mapping of soil degradation potency in paddy field is an identification of initial soil condition to discover the land degradation potency. Mapping was done by overlaying map of soil, slope, rainfall and land use with standard procedures to obtain its value and status of soil degradation potency. Area mapping is an effective land for biomass production (natural forest, mixed farm, savanna, paddy field, shrub and dry field) with approximately 43,291.00 hectares (ha) in Sidoharjo, Girimarto, Jatipurno, Jatisrono, Jatiroto, Tirtomoyo, Nguntoronadi and Ngadirojo District. The result shows that soil degradation potency (SDP) in Districts of Sidoharjo, Girimarto, Jatipurno, Jatisrono, Jatiroto, Tirtomoyo, Nguntoronadi and Ngadirojo are very low (DP I) 0.00 ha (0.00%), low (DP II) 20,702.47 ha (47.82%), moderate (DP III) 15,823.80 ha (36,55%), high (DP IV) 6,764.73 ha (15.63%) and very high (DP V) 0.00 ha (0.00%). Paddy field is 22,036.26 ha or about 50.90% of all area as effective biomass production, its SDP considers as low (DP II) 16,021.04 ha (37.01%) and moderate (DP III) 6,015.22 ha (13,89%). Paddy field has a low SDP because it is commonly lies on flat area and conservation method by the farmer is maintaining the paddy bund and terrace. This study needs an advanced study to identify actual SDP through detail verification in the field, and also support by soil sample analysis in the laboratory.
