Abstract

Sorghum is a potential crop as feed forage. The objective of the research was to obtain optimum dose of liming to improve the growth and productivity of sorghum (Sorghum bicolor (L.) Moench) biomass as feed forage. A completely randomized design with 4 treatments and 4 replications were applied for the research. The treatments were doses of dolomite lime addition i.e., 1) SD0 (dolomite lime addition at a dose of 0 ton/ha) as a control, 2) SD1 (dolomite lime addition at a dose of 1 ton/ha), 3) SD2 (dolomite lime addition at a dose of 2 ton/ha), and 4) SD3 (dolomite lime addition at a dose of 3 ton/ha). The result shows that supplementation of dolomite lime at doses of 2‒3 tons ha-1 can increase soil pH after a week of incubation. The dolomite lime addition at a dose of 3 tons ha-1 significantly increases (P<0.05) the plant height (2 weeks after planting) and the number of leaves from a week after planting until the end of the research (10 weeks after planting). In addition, this dose of dolomite addition (3 tons/ha) can increase fresh biomass productivity as well as dry biomass compared to control (SD0). In conclusion, supplementation of dolomite lime at a dose of 3 tons ha-1 was effective to increase the pH value of soil, plant height, leaves number, as well as fresh and dry biomass of sorghum plant. In addition, this dose of dolomite lime produces better green color of sorghum plant leaf compared to without liming. Keywords: biomass production, dolomite lime, feed forage, Sorghum bicolor (L.) Moench

Abstract

Entisol has poor physical, chemical, and biological properties that limit the growth and yield of maize. This study aimed to obtain the correct dose of vermicompost to increase the growth and yield of maize on Entisols. The research was arranged using Randomized Block Design, consisted of 7 treatment doses of vermicompost fertilizer (0; 2.5; 5; 7.5; 10; 12.5; and 15 Mg ha-1 and 4 re;plications. The results showed that the dose of vermicompost significantly affected the growth and yield of maize in coastal entisol soils. The dose of 10 Mg ha-1 was the best on plant height, leaf number, fresh weight, plant dry weight, shoot fresh weight, fresh root weight, and shoot and root dry weight. Meanwhile, the dose of 12.5 Mg ha-1 produced the best maize yields for the fresh weight of husked ear per plant, fresh weight of unhusked ear per plant, and dry grain weight per plant, namely, 322.75 g, 286.66 g, and 173.4 g, respectively. The best results of fresh weight of husked ear per plot, fresh weight of unhusked ear per plot, and dry grain weight per plot were achieved by vermicomposting of 15 Mg ha-1, which were 11.28 kg, 9.72 kg, and 5.94 kg, respectively. Keywords: coastal, Entisol, maize, vermicompost, yield

Abstract

Katuk (Sauropus androgynus), a traditional herb that has been traditionally consumed by breastfeeding mothers to increase their milk production but still has some side effects, such as bronchiolitis obliterans and inhibition of calcium absorbtion. Removing the polar compounds in katuk leaf (depolarized katuk leaf) can eliminate those side effects without eliminating its side effect in increasing milk production and body growth in several production animals. This study was aimed to analyze the physiological status of beef cows consuming diet supplemented with depolarized katuk leaf as feed additive by measuring their hematology and blood mineral profile. Nine Brahman cross cows in the finisher stage, were grouped based on their diet: complete feed (control), complete feed plus depolarized katuk leaf powder (P1; 100 g per day), and complete feed plus depolarized katuk leaf pellet (P2; 100 g per day). Blood sample was collected after six weeks of consumption for analysis of hematological profiles including total erythrocytes, hematocrit, hemoglobin, total leukocytes, stress index (neutrophil-lymphocyte ratio); and blood mineral concentration (calcium and phosphorous). Dietary administration of depolarized katuk leaf did not have any statistically significant effect on all hematology parameters and blood mineral profiles. In conclusion, depolarized katuk leaf can be used as a growth promoter in beef cows without any negative effect on their physiological status.

Abstract

Nitrogen (N) fertilizer of the urea type is very commonly used in Indonesia. The demand for this fertilizer is expected to increase, so an alternative is needed as a complement. Ammonium chloride (NH4Cl) is a by-product produced in the soda ash industry. This compound contains 26% N, which can be an alternative source of N nutrients for plants. The level of the following element, namely chlorine (Cl), is relatively high, so it is a concern that might affect the plant growth. This field experiment aimed to evaluate the effect of the application of ammonium chloride combined with potash fertilizers on the growth, production, and uptake of N and Cl nutrients in sweet corn plants. The trial was designed in a randomized group with nine treatments of 0%, 100%, 150%, and 200% N, combined with potassium sources from KCl and K2SO4. As a comparison, the source of N is urea at a dose of 100% N is referred to as the standard N treatment. Parameters observed included plant height, the weight of corn cobs and corn stover, N and Cl nutrient uptakes in seeds, leaves, and stems. The results showed that the application of ammonium chloride combined with different K sources markedly affected plant height, cob and plant stover weight, and N and Cl uptakes of sweet corn compared to controls. Applying N-ammonium chloride with KCl and K2SO4 showed no significant effect in growth and yield compared to standard N. The N dose showed no significant effect on plant growth and yield compared to the standard N dose. Keywords: by-product, nitrogen fertilizer, soda ash

Abstract

Bogor is one of the cities with a very rapid development rate, so the need for sand for construction is very high. There are plenty of sand sources in Bogor, feeding by 2 major rivers and 7 tributaries, including the Ciapus River. This river is a job opportunity for sand miners. Based on the study results, the traditional sand mining model is applied. The income from the sand miners is IDR100,000/m3, while the income from the collectors who also distribute the sand to the users is IDR150,000/delivery. The positive impact of this activity is that it can reduce sedimentation in the Ciapus River, while the negative impact is that it caused a change in the shape and function of the river and the road damage around the mining due to the sand transportation, but not on the road within the housing area. In the long term, this activity needs more attention because until now, the Bogor Kota Government still needs to have a regulation regarding type C mining.

Abstract

The difference in seasonality in the red chili farming business affects the allocation of the use of production factors and the availability of its supply in the market, which is suspected to affect the cost structure and revenue of the farming business. This study aims to calculate the cost structure, revenue, and earnings of red chili farming businesses in the dry and wet seasons in Central Java Province. Data was collected from the 2013 Agricultural Census: 2014 Horticultural Crop Business Household Survey and a 2535 red chili farmers sample. The methods used include the analysis on income, cost and revenue structure, revenue, R/C ratio, and Mann-Whitney differential test. The results showed that the cash and overall costs of farming red chili in the dry season were higher than in the wet season. So are the total and cash revenues. Farming in the dry season is more profitable in terms of cash income, net farm income, R/C ratio, return to total capital, and return to land, which is higher than in the wet season. The results of the Mann-Whitney difference test showed a significant difference in the income factors and R/C ratio of the red chili farm business in the two seasons. Keywords: cost structure, income, R/C ratio, red chili, season

Abstract

Pathogenic microbes are the limiting factor in increasing red chili productivity. These pathogens cause decreasing yield of red chili up to 50-100%. This research aimed to characterize and evaluate disease severity on 20 red chili genotypes caused by pathogenic microbes. The research was arranged in Randomized Complete Block Design with three replications. The samples were 20 chili genotypes, namely UNIB K01, UNIB CGTS1, G35, G48, G56, G60, G67, G77, and G43 (developed by the University of Bengkulu researchers) and IPB C19, COPAY, IPB C495, IPB C14, DORSET NAGA, IPB C4, IPB PANJANG, LOKAL BENGKULU, SELOKA, SSP, and ANIES (developed by others). The results showed that four groups of pathogens attacked red chili, namely Fusarium oxysporum, which causes fusarium wilt disease; Cercospora sp., the cause of leaf spot disease; Colletotrichum sp. causes anthracnose; and virus groups. All tested red chili genotypes could be infected by these four pathogens in which the incubation period, disease incidence, and disease severity were insignificant. Of the nine genotypes developed by the University of Bengkulu researchers, the G35 genotype had the best potency to be developed as a disease-resistant genotype.

Abstract

The subterranean termite Coptotermes curvignathus is a type of insect that damages wood until it is porous and destroyed. Until now, termites are chemically controlled but negatively impact the environment, so bioinsecticides such as from Usnea barbata lichen are needed. This study aims to determine the bioactivity of U extract. Barbata as a bioinsecticide for subterranean termites C. curvignathus. The experiment used Completely Randomizd Design with 7 treatments (concentrations of 0%, 5%, 10%, 15%, 20%, 25%, and Termicon) and 3 replicates. The extract was prepared from 300 g of U barbata powder, macerated in 7 days in 96% ethanol in a ratio of 1:10 (300 g/3 L). Mortality and feed weight loss were observed for 7 days. The extracts contained alkaloids, flavonoids, terpenoids, steroids, saponins, and tannins. The phytochemicals were analyzed descriptively, and a lethal concentration value of 50% (LC50) was determined by probit analysis. Data on termite mortality percentage and feed loss percentage were analyzed using ANOVA at a 5% confidence level. If the Fcalct > Ftable, Duncan's further test was carried out. The results showed that the extract contained alkaloids, steroids, tannins, and saponins. The mortality of subterranean termites was indicated by an LC value of 50-72 hours of 19.32%. Statistically, U. barbata extract affected mortality but did not differ significantly in the feed weight loss of C. curvignathus subterranean termites.

Abstract

Arbuscular mycorrhizal fungi (AMF) is a fungus that has a symbiotic impact on the plant at the root system level. The research objective was to evaluate the growth of Indigofera zollingeriana produced from inoculation of AMF under different fortification and fertigation techniques at the field scale. A completely randomized design with six treatments and five replication were applied for the study. The treatments were: FD1000, FD2000, FD3000 (AMF fortified with 1000, 2000, and 3000 ppm of AB mix at flat fertigation), FB1000, FB2000, and FB3000 (AMF fortified with 1000, 2000, 3000 ppm of AB mix at graded fertigation). The result shows that the AMF colonization level at the root of was similar (P>0.05) to the upper value of colonization (80.00‒99.00%). The entire products of AMF have similar favorable symbiotic effects on the plant with major growth traits (plant high, stem diameter, number of branches and twigs). A fortification of 2000 ppm of AB mix under graded fertigation technique has produced AMF that significantly (P<0.05) increased the number of leaves with higher green color level (7.5GY 4/6) compared with other treatments. In conclusion, the AMF produced by different fortification and fertigation techniques at the field scale has a similar result on root colonization effectivity and growth performance of I. zollingeriana. In addition, the AMF produced by 2000 ppm of AB mix with graded fertigation technique effectively increased the number of leaves with higher green color intensity.

Abstract

Pineapple (Ananas comosus L. Merr) is a plant that can live well on nutrient-poor lands such as peatlands. However, plant resistance to nutrient-poor conditions is caused by symbiosis with endophytic bacteria capable of plant growth-promoting bacteria (PGPB) through biostimulant and bioprotective mechanisms. This study aims to characterize the potential of endophytic bacteria from pineapple roots from peatlands as biostimulants and bioprotective agents. Thirteen endophytic bacteria from pineapple root were characterized by their ability as biostimulants through phosphate dissolution tests using Pikovskaya media qualitatively and quantitatively, and the production of indole-3-acetic acid (IAA) upon additional 0.1% tryptophan. Furthermore, bacteria as bioprotectors were characterized by qualitative production of chitinase enzyme and antifungal tests against Fusarium proliferatum using dual culture techniques. The results showed the presence of 2 positive bacteria in all tests, namely the ANAP3 and ANAP5 isolates. ANPA3 bacteria show the highest activity in IAA production (26.3 ppm), and the highest antifungal activity in inhibiting F. proliferatum, with an inhibitory index reaching 52.6%. Meanwhile, ANAP5 is an endophytic bacterium with the highest phosphate dissolving activity, with a dissolved phosphate value of 253.5 ppm. This finding shows that some endophytic bacteria from pineapple roots on peatlands can be biostimulants and bioprotectors that can be developed as PGPB. Keywords: Ananas comosus L. Merr, endophytic bacteria, bioprotectant, biostimulant, Fusarium proliferatum
