Publisher : Central Research Institute For Agriculture

The purpose of this study was to determine the productivity of eight varieties of large red chili (Capsicum annum L) against fertilization levels grown inorganically in the lowlands. Observations made in this study included non-destructive, destructive and harvest observations. Among others: Number of branches per plant, plant height, number of leaves, number of flowers, number of fruit, fruit set, for destructive observation is the measurement of leaf area, while for harvest observation: fresh weight of fruit planted, fresh weight of fruit per plot, number of fruit per plant, fruit size, number of fruit that are attacked by pests. Analysis of the observed data used analysis of variance (F count). If there were significant differences between the treatments, a Least Significant Difference (LSD) test was carried out with an error rate of 5%. Based on the research results from observational data, it shows that several doses of inorganic fertilizers on 8 large chili cultivars did not produce any interactions. Likewise with the use of inorganic fertilizers with large chili cultivars with doses of P1: Urea 100kg ha-1 + Sp-36 150 kg ha-1, P2: Urea 175 kg ha-1 + Sp-36 300 kg ha-1, and P3: Urea 250 kg kg ha-1 + Sp-36 450 kg ha-1 had no effect on the various observed variables. Significant effect was obtained from the use of various varieties of chili peppers. These significantly different responses were shown by the variable plant height, production per plant and yield components. Based on plant height observation data up to 84 hst, Jet set had the highest height compared to the other cultivars, which was 32.13% higher than Horizon cultivar. Meanwhile, based on yield component data, the Horizon cultivar produced the highest yield, which was 6.96 ton.ha-1, while the lowest was produced by the Hot Chili cultivar, which was 1.66 ton.ha-1.

This study aims to determine the effect of concentrations of Rooton F, young coconut water, and cow urine on the growth of cuttings patchouli stem. Patchouli plant (Pogostemon cablin Benth.) is one of the important essential oil producing plants. The export volume of essential oils has always increased, in 2001 it reached 5,080 tons. Indonesia is the main supplier of patchouli oil in the world, which is almost 90% of the world's needs (Emmyzar, 2004). However, in recent years, patchouli oil exports have shown a downward trend. The cause of the decline was the limited ability to produce patchouli oil. Therefore efforts to increase the production of patchouli oil by way of development patchouli plants wide open. One of these efforts can be done by producing patchouli plants that have good quality. Patchouli plant propagation can be done by cuttings. The success of cuttings can be seen from their roots. Good rooting will produce quality plants fine too. Auxin is a type of plant hormone that can stimulate root growth. Rooton F is an example of a synthetic ZPT ingredient, while young coconut water and cow urine are natural ZPT ingredients. The three materials have their advantages and disadvantages. With the difference in the content of the three ingredients, it will also have a different effect on the growth of patchouli cuttings. In observing the number of leaves aged 6 wap, 75% rooton-F gave a yield of 4.67 leaves and was not different from the treatment of 75% coconut water, 50% cow urine, and 100 cow urine. At 5 wap, 75% and 100% treatments gave the effect is the same and different from other treatments.

(Colony area, dry weight and number of spores) and antagonistic activity of Gliocladium sp. in inhibiting Foc. The research was conducted at the Laboratory of Plant Diseases, Department of Plant Pests and Diseases, Faculty of Agriculture, University of Brawijaya. The stages in this study included counting colony area, sporulation and dry weight of Gliocladium sp. with single culture method, antagonism test between Gliocladium sp. and Foc with dual culture method. In the research stage to determine the effect of salt levels used NaCl, with concentrations of 0 gr/l, 4 gr/l, 8 gr/l, 12 gr/l and 16 gr/l. The design method used in this study was a completely randomized design (CRD). Banana plants can grow in tropical climates with a pH of 4.5-7. In banana cultivation there are several obstacles that can reduce banana production, the main obstacle is caused by the attack of the pathogen Fusarium oxysporum f. sp cubense (Foc) which causes banana plants to wilt. Efforts to control the attack of pathogenic Foc, can be done by utilizing the antagonistic fungus Gliocladium sp. The results showed that the colony area, sporulation and dry weight of Gliocladium sp. showed that overall growth increased with increasing salt content used, the results obtained were colony area, sporulation and dry weight of Gliocladium sp. The highest yield was found in the treatment with a concentration of salt content of 16 gr/l, with values of 4.184 cm2, 7.933 spores/ml and 0.132 gr respectively, while the antagonism test between Gliocladium sp. and Foc, the highest inhibition percentage of Gliocladium sp. occurred at a salt concentration of 16 gr/l of 45.556%. The research shows that the addition of NaCl to the media has a positive effect on Gliocladium sp.

This study aims to determine the effect of the dose and application time of T. polysporum on the effectiveness of controlling Fusarium wilt in tomato plants. Fusarium wilt disease (Fusariun oxysporum) is an important disease in various cultivated plants, especially tomato plants. Fusarium wilt occurs in all tomato growing areas around the world and causes huge losses of up to 60%. Control of F. oxysporum pathogens using fungicides on agricultural land can cause environmental pollution. One of the environmentally friendly control alternatives is to use the biological agent Trichoderma polysporum. The results showed that compost containing T. polysporum was effective for controlling Fusarium wilt in tomato plants. The percentage effectiveness of compost containing T. polysporum in controlling the intensity of disease attacks, namely 0% in the control treatment, 47.80% with the application of 0.25 kg of compost containing T. polysporum, and 70.87% with the application of 0.5 kg of compost containing T. polysporum. The effect of time of application of compost containing T. polysporum is equally effective for controlling the pathogen attack of F. oxysporum. The large doses of T. polysporum compost applied prior to inoculation of the pathogen can increase plant growth and yield. In the application of 0.5 kg of compost containing T. polysporum, the highest growth in plant height was 18.03-19.84 cm, while the lowest growth average was in the control treatment of 16.53-16.70. The highest average plant production, namely 237.65 grams, was found in the application treatment 0.

Publisher : Central Research Institute For Agriculture

This study aims to determine the effect of the compost application on P availability in Alfisols and to compare the compost application through leaves and soil to the P uptake of corn plants. The low availability of P in Alfisol is due to the bond with Ca to form tricalcium phosphate which is difficult to dissolve. One effort that can be done to overcome the lack of P in Alfisols is the addition of organic matter to the soil, both from plants and animals. The final process of decomposition of organic matter produces humic and fulvic acid compounds which can increase the availability of P. Compost tea is the result of a solution of washing nutrients and extracts of bacteria, fungi, protozoa and nematodes from compost. Compost tea can be given in two ways, namely by spraying it through the leaves and giving it to the soil through the leaves and the soil against the P uptake of corn plants. Compost tea is made using the Bubbler method. Before being applied, the compost must be diluted with distilled water (1:1 ratio) to reduce the concentration. The experimental design used in this study was a completely randomized design with 7 treatments and 3 replications with the following types of treatment: CT0 (control); CT1 (soil + compost tea 130 ml/plant equivalent to 50 l/100 m2); CT2 (soil + compost tea 250 ml/plant equivalent to 100 l/100m2 ); CT3 (soil + compost tea 400 ml/plant equivalent to 150 l/100 m2); CT4 (soil + compost tea 60 ml/plant equivalent to 25 l/100 m2); CT5 (soil + compost tea 130 ml/plant equivalent to 50 l/100 m2); CT6 (soil + compost tea 200 ml/plant equivalent to 75 l/100 m2); The results showed that the application of compost tea through the leaves and soil had a significant effect on the difference in available-P levels. Application of the compost through the leaves increased plant height, number of leaves, plant dry weight and P uptake. There was a positive correlation (r=0.386) which showed that increasing available P levels in the soil would increase plant P uptake.

The purpose of this study was to study the effect of the thickness of low density polyethylene plastic as a packaging material for White Oyster Mushrooms on the modification of O2 and CO2 gases and the physical changes that occur during storage. P Completely randomized design (CRD) was used to analyze data on changes in the composition of O2 and CO2 and followed by a T test if the analysis of variance showed that different treatments had a significant effect on changes in O2 and CO2 concentrations. The results of the diversity test showed that the treatment of differences in LDPE plastic thickness had a very significant effect on the concentration of O2 and CO2 gases in the plastic packaging. The thickness of LDPE plastic 0.04 mm is the best thickness that is able to maintain the quality of white oyster mushrooms with a texture value of 0.022 mm/g.sec, weight loss of 0.74%, reduction of water content of 1% and an average minimum oxygen concentration in the package of 3.2 % and the maximum concentration of carbon dioxide in the package is 8.2%. The highest decrease in water content at 0.03 mm thickness was 1.3% and the lowest at 0.08 mm thickness was 0.63%. The lowest respiration rate was 21.71 mlCO2/kg/hour which occurred at a thickness of 0.08 mm on the 5th day of storage. If the respiration rate of a commodity can be matched with the permeability of the film on the package, then a favorable passive atmosphere condition can be achieved within the package. This method is commonly known as Modified Atmosphere Packaging (MAP).

This study was conducted to determine the effectiveness of using N, Si fertilizers at certain doses to prevent further attacks caused by SCSMV. The results showed that each increase in the dose of N fertilizer on sugarcane plants will accelerate the incubation period with a regression value of 1.038% and affect the increase in intensity SCSMV attack of 3,063%. At each increase in fertilization the dose of Si can inhibit the incubation period of SCSMV and can decrease SCSMV attack intensity of 7.018%. There was no significant difference in the growth of sugarcane shoots in the F test. The use of N dose of fertilization would affect the growth process, such as plant height in increasing the N dose would affect the highest plant height increase in the 8 kw/Ha treatment. In the Si fertilization treatment there was a significant difference that each increase in dose would increase the process of plant height growth. Sugarcane (Saccharum officinarium L.) is one of the plants belonging to the grass species (Gramineae). This plant is used as raw material for sugar. Low sugar production affects the fulfillment of national sugar needs. Many things can affect the decline in sugar production, including the explosion of pests and sugarcane plant pathogens. One of the main pathogens is Sugarcane streak mosaic virus (SCSMV) which in recent years has attacked sugarcane plantations in Indonesia. The role of many nutrients needed by plants. The use of appropriate N nutrients can increase yields, and the application of Si elements can protect plants from OPT attacks.
