Abstract

This study aimed to investigate the biochar effect on peat soil fertility and uptake of nitrogen, phosphor, and potassium by corn plants. The experiment was conducted at a greenhouse in the Indonesian Swampland Agriculture Research Institute (ISARI), Banjarbaru, South Kalimantan, from June to September 2014. The peat soil sample was collected from the village of Kalampangan, Palangkaraya, Central Kalimantan. The treatment consisted of four types of biochar, namely coconut shell, palm midrib, Galam stem (Melaleuca leucadendron), rice husk and five rates of biochar i.e. 0, 2, 4, 8 and 16 t ha-1. Biochar was analyzed in total C, P, K, Ca, Mg, Fe, Si, ash content, pH and CEC, also initial soil sample was analyzed  pH, EC, organic C, total N, P, available P, exchangeable K, Ca, Mg, H, Cu, Zn, and total acidity were measured. The application of biochar changed peat soil properties including pH, available P, exchangeable K, nutrient uptake and the dry weight (i.e root and shoot). The type of biochar significantly affect the exchangeable K in peat soil and nutrient uptake. The highest exchangeable K and NPK uptake by corn showed by the coconut shell biochar at dose 4 t/ha.

Abstract

Foxtail millet is relatively tolerant to salinity stress and thus can be grown in salinity affected areas. This study was conducted to identify anatomical changes in the roots of foxtail millet genotypes with different tolerance level to salt stress. Four foxtail millet genotypes, namely ICERI-5 and ICERI-6 (salt tolerant) and ICERI-4 and ICERI-10 (salt sensitive), were grown hydroponically for 1 week prior to 60 and 120 mM salt stress treatments. Root anatomical changes were observed on the fifth day after treatments. The results showed that salt stress significantly induced some anatomical changes in the roots of foxtail millet, i.e. increased epidermis and cortex thickness, increased root diameter, and increased the number of root hairs. The increase in epidermis thickness, root diameter and the number of root hairs due to the salt application were more pronounced in the sensitive genotypes. Number of protoxylem in the tolerant genotypes were significantly increased due to salt stress, however salinity significantly decreased the number of protoxylem in the sensitive genotypes. The different anatomical changes under salt stress between the tolerant- and sensitive genotypes indicated that some anatomical attributes of the roots might determine the salt tolerance level of foxtail millet.

Abstract

The physiological response of cocoa plants under VSD infections is still limited because there is no method in artificial inoculation since Oncobasidium theobromae was reported as parasitic obligates. The investigation of correlation between cocoa responses and VSD attack becomes important information to figure out the effect of decreased productivity as the consequences of the physiological damages. The objective of this research was to describe the pathogen infection and the symptom of VSD through fungal staining method and to asses the changes of some physiological aspects (chlorophyll and gass exchange character) under VSD pathogen infection. This study was conducted in Kaliwining experimental station, ICCRI, Jember, East Java, Indonesia. The result of the study indicated that late infection stage caused chlorophyll degradation, decreasing transpiration rate, and increasing temperature in both tolerant clone (Scavina 6) and susceptible clone (TSH 858). The rate of photosynthesis, stomatal conductance, and concentration of CO2 in susceptible clone (TSH 858) showed a drastic decrease when infected by VSD pathogen than that of in healthy plants. In resistant clone (Scavina 6), photosynthesis rate, stomatal conductance, and concentration of CO2 showed no significant decrease when infected by VSD pathogen compared to that non-infected condition.

Abstract

An environment is strongly affected plant growth, particularly under drought condition. The obstacle for this condition can be maintained by water and nitrogen sources. The aim of this research was to determine and observe the effect of N-encapsulation on the distribution of macro nutrients in the vegetative and generative phases of rice plants (Oryza sativa L.) during rice growth. The difference of nitrogen sources will influence the nutrient absorption by roots. This research was conducted in June to September 2018 at field experiment in Batu, East Java, Indonesia. The method used a Randomized Block Design with the first factor was nitrogen sources and the second factor was field capacity as drought levels. The result showed that the proline content was 0.67 µm/g in plant treated by Urea which is higher and following by N-encapsulation at 0.52 µm/g. The proline strongly maintained grain-filling phases until field capacity 25 % at the entire nitrogen source (N-encapsulation, ZA, Urea) are 72.73 g; 69.93 g; and 66.15 g respectively. At 25 % field capacity induced length of roots and had the lowest number of tillers at 30.55 by N-encapsulation and less number of panicles was 19.33 per clump. The N accumulations were maintenance in higher concentration of leaves at 100 %field capacity compared with the other treatments.

Abstract

The effort to reduce chemicals has become an important issue in floriculture agribusiness. The chemicals included fungicides for white rust control in chrysanthemum. The combined application of synthetic fungicide with biological agent and botanical fungicide were expected not only to reduce synthetic fungicide application, but also suppressed the white rust attacks. The research was conducted at the Indonesian Ornamental Crops Research Institute (IOCRI). A factorial randomized complete blocked experiment was designed to facilitate combined applications of hexaconazol-50 (SFH-50), antagonist microbe Corynebacterium sp. (Cor-5) and formulated botanical fungicide CEES 50EC (ES-50). The results showed that the combined SFH-50 with Cor-5 and ES-50 merely affected the disease intensity, yet less on white rust incidence, period of disease emergence, plant growth, flower production and quality. All combined applications of SFH-50 with Cor-5 and ES-50 showed lower disease intensity than single SFH-50. Higher suppressions were detected on 1 ml/l SFH-50 + 5 ml/l Cor-5-3 and 1 ml/l SFH-50 + 2 ml/l ES-50-3. The use of antagonist microbe and botanical fungicide singly or in combination with synthetic fungicide could reduce with the higher affectivity than single synthetic fungicide application.

Abstract

In the recent years, basal plate rot (BPR) caused by Fusarium oxysporum f. sp.cepae (FOCe) is one of the important constraints of shallot production in Indonesia. This research aimed to study the potential of S-oxidizing bacteria (SOB) as biological control agents to inhibit FOCe and provide available-S to shallot on Andisols. An experiment in laboratory was conducted to evaluate the capabilty of SOB in oxidizing S in liquid medium and a pot experiment was aimed to evaluate the capability of SOB in providing available-S and inhibiting infection of shallot by FOCe in Andisols. All treatments were arranged by a Completely Randomized Design with three replications. The data were analyzed by F test, followed by Duncan’s Test.The results showed that the capability of oxidizing S in a liquid medium increased after the incubation for six days, with the highest concentration of soluble-S was taken from SOB2 isolate. The isolate provided the highest available-S, while the highest capability of decreasing the disease incidence was taken by SOB3 and SOB1+2+3. SOB3 isolates promoted the highest growth of shallot. So it has a tremendous potential if they are used as an inoculum of bio-fertilizer and biological control agent of BPR of shallot.

Abstract

There is limited information and insures for next studies on exogenous brassinolide application fig cultivar of Masui Dauphine (MD) and Improved Brown Turkey (IBT). Therefore, the research objective was to determine the impact of concentrations of exogenous brassinolide application on Leaf Area Index (LAI), Leaf Mass Ratio (LMR), Net Assimilation Rate (NAR), Relative Growth Rate (RGR), and Specific Leaf Area (SLA) of fig. Fig resources were propagated using stem cuttings and were transferred into 3:2:1 mixed soil (topsoil:organic matters:sand) media. Two cultivars of fig treated with brassinolide (control, 50, 100 and 200 ml/L) were repeated four times and constructed by Split Plot Randomized Complete Block Design.  Changes in the parameter of LAI, LMR, NAR, RGR, and SLA were investigated monthly. There was a significant effect of fig variety alone on LAI, SLA and LMR but it wasn’t affected on NAR and RGR. SLA and LMR were influenced by brassinolide but not on LAI, NAR and RGR. Cultivar IBT showed higher responses to these parameters than cultivar MD after receiving brassinolide treatment. The interaction between brassinolide and variety was significant on LAI, SLA and LMR of fig except in the parameters of NAR and RGR.

Abstract

The objective of this study was to investigate a method of measuring bamboo diameter at breast height (DBH) for biomass estimation using Monte Carlo sampling. The data for this study were collected in Paung Laung Reserve Forest, Myanmar. The research developed two different methods for determining required sampling numbers based on changes in the coefficient of variation (CV) with the sampling ratio and sampling size using 37 plots of bamboo. These sampling numbers were derived from the sampling ratio with a CV less than 10 % and the stability of the CV. The error ratios of the two results between measured and estimated bamboo biomass were 6.0 % and 6.9 %. It will be necessary to assess the balance between the estimation accuracy and survey time for carbon stock estimation of bamboo, which is indispensable for an accurate forest carbon accounting in Myanmar.

Abstract

The escalating demand of shallot has forced the increase of domestic production, including through extension of harvest area by utilization of arable land on peatland. This study was aimed to analyze genetic profile of shallot adapted in peatland areas using SSR markers. Twenty-one shallot genotypes were tested in the field and eighteen primers dispersed throughout the genome was applied to analyze genetic diversity of the peatland-adapted shallots. Phenotypic evaluation revealed that shallot yield potential ranged from 6.66 to 14.21 t/ha. Of these, seven shallot clones (11 NA, 1111 TA, 12 NA, 12 NC, 20 NA and 22 N) had good yield potential and comparable with those of five released shallot varieties. Nine out of 12 shallot clones were moderately resistant to Alternaria porii. Clustering analysis showed that shallot genotypes were clustered into two main groups, Clustered I and II which consisted of 13 and 8 genotypes, respectively. The closest genetic relatedness was observed between 8NC and 8NA (0.85), while the farthest ones was between 11NA and Kramat2 (0.51). This result implies that cross combination between 11NA and Kramat2 is valuable and suitable for breeding programs aimed at improving shallot potential yield in the future.

Abstract

West Indian arrowroot (Maranta arundinacea L.) is a tuber crop that is consumed as an alternative food. İt can grow in an area with altitudinal range from 0 to 1,000 m asl. This study aimed to analyse physiological response and photosynthate distribution which is related to growth performance and tuber yield of West Indian arrowroot at two different altitudes. Four accessions of West Indian arrowroot i.e. Bantul, Krajan, Kemalang, and Begawat were planted at 250 and 1,100 m asl. This study was conducted using split plot design with altitude as the main plot and the accession of West Indian arrowroot as a subplot. The results showed that altitudes significantly affected physiological response, plant height, leaf area per plant, and tuber yield of West Indian arrowroot. The rate of photosynthesis in the highland tended to be higher than that in the lowland, but plant height and tuber yield were lower in highland. These results suggested that the West Indian arrowroot had different pattern on photosynthate distribution between shoot and tuber at different altitudes because of environmental factors. Bantul accession had the lowest tuber yield compared to the others, and showed the low ability of accession Bantul in distributing photosynthate towards tuber.
