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

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

The difficulty of seeding and sweetness quality of seedless watermelon is an obstacle for farmers. 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

Evaluation of soil fertility status on agricultural is to know the fertility of soil chemically through soil analysis or soil test. This is done to obtain estimates data of land characteristics based on parameters observed and tested for various alternative uses based on specific objectives. Parameters used to assess soil fertility status are Cation Exchange Capacity (CEC); Bases Saturation (BS); Organic Carbon; Total P and K levels. Evaluation of soil fertility status is needed as an effort to know the potential and direction of the management of production land on the cultivation of agricultural crops, and to know the factor of fertility that limits on the land. Based on the above description, it is necessary to evaluate the status of soil fertility in Tirtomoyo District in order to be used in the effort to provide and increase food sustainability for Wonogiri region and able to increase the economy level and income for the farmers. The results showed that the soil fertility status in all areas of Tirtomoyo District classified into the low category. This is due to the low value shown in almost all observation parameters; Cation Exchange Capacity (CEC); Base Saturation (BS); Organic Carbon; Total P and K levels. The limiting factor of soil fertility status caused by a very low Total P value of 2.16 mg 100 g-1 to 14.19 mg 100 g-1, and Organic Carbon which is low with 0.4% to 1.7%.

Abstract

The utilization of red mud, which is a residue from the extraction of aluminum from mined bauxite ore, as a plant growing medium, needs to be studied further. There are some chemical aspects that may hinder the growth of, or even cause mortality in, plants such as very high pH, electrical conductivity (EC) and exchangeable Na (Naexch), and very low nutrient elements content.  The objective of this study was to investigate the effects of adding Ultisol soil material, mixed with compost, both soil ameliorating agents, to red mud for use as a growing medium for Sengon (Paraserianthes falcataria) seedlings. This study was conducted in two stages, namely: washing of the red mud, and trial planting in the greenhouse using different combinations of the soil ameliorants. Washing of the red mud with tap water was intended to reduce the levels of Na, EC, and pH. Trial planting in the greenhouse was carried out in 2-factorial Completely Randomized Design (CRD). Factor 1 was the proportion of the mixture of Ultisol soil material (sm-Ultisol) and red mud, viz: (1) 1500 g red mud + 0 g sm-Ultisol, (2) 1000 g red mud + 500 g sm-Ultisol, and (3) 750 g red mud + 750 g sm-Ultisol.  Factor 2 was the dosage of compost that was mixed with the red mud and sm-Ultisol, namely: 0, 58.6, and 117.2 g/polybag which corresponded to 0, 2.5 and 5 kg/planting hole, respectively. The results of the trial indicated that washing the red mud could reduce the level of EC from 28.70 dS m-1 to 2.68 dS m-1; but it reduced pH and Naexch only from 11.91 and 149.38 cmol(+)kg-1 to become 10.55, and 66.74 cmol(+) kg-1, respectively. A better outcome was obtained after the red mud was washed and then, mixed with sm-Ultisol up to 1:1 proportion in which resulted in lower rates of pH, EC, and Naexch from 10.28, 2.53 dS m-1 and 62.79 cmol(+) kg-1 to 8.65, 2.07 dS m-1 and 45.01 cmol(+) kg-1, respectively. The treatment of using a mixture of 750 g red mud + 750 g sm-Ultisol, and adding compost at 117.18 g/polybag gave the best result in improving the chemical property of the red mud growing medium, and producing the best plant growth among all treatment combinations.

Abstract

Growing rice had been done previously by applying crumble compost on the floating raft but part of compost was lost through runoff, so briquettes compost needs to be buried in soil.  The aims of this research were to find out the effects of briquettes compost and liquid fertilizer on rice and soil and plant nutrients content. Briquettes compost and liquid fertilizer were made of water mimosa (Neptunia prostrate Lam.).  Briquettes were applied at rates of (0, 10, 20 and 30) ton ha-1 and liquid used at (0 and 20) ml clump-1.  This experiment used Factorial Randomized Block Design.  Briquette compost was made by mixing compost with starch and the application was by inserted into the soil.  Liquid fertilizer was made from extracted compost and the application was sprayed on plant leaves.  Results showed that the application of Briquette compost (10 ton ha-1) increased (0.34%) P and (1.88%) K plant contents significantly, compared to the control treatment were only (0.09%) for P and (1.38%) for K plant contents.  Combination of briquettes compost (20 ton ha-1) and liquid fertilizer (20 ml clump-1) increased dried weight rice significantly to (4.55 ton ha-1)from (1.58 ton ha-1) for control treatment. Briquettes compost inserted into the soil had increased nutrients P and K absorbed due to more contact between roots and nutrients and produced more rice yield.
