Abstract

The present study, a part of a series of studies carried out to explore the possibility of beetroot cultivation in the tropics on highlands, was designed to investigate the growth and betacyanin content of beetroot plants in response to water deficit in a tropical condition. The water deficit was executed through varied watering intervals consisting of once three (as control), four, five, six and seven days. A randomized block design with five replicates was used to impose the treatments. The effect of water deficit was found to reduce the leaf water content, the biomass production (total dry weight) and the root yields of beetroot plants. Root dry weight decreased by more than 20% and 50% with the watering interval once four and seven days respectively compared with that once three days. The betacyanin content of roots was not influenced by the water deficit when expressed per unit volume of fresh root extracts (340.5 ± 60.1 mg/l), and increased when expressed per unit root dry weight. It is suggested that an optimal supply of water, for instance watering once three days, is necessary to obtain beetroot plants growing optimally and producing a high root yield and betacyanin content of roots.

Abstract

Five Cytoplasmic Male Sterility (CMS) lines and four restorer lines (tester) were crossed in a line x tester scheme in order to analyze general and specific combining abilities and gene effects on sunflower for some agronomic and physiologic traits. Hybrids were evaluated in a randomized complete block design, with three replications under optimum and limited water conditions. The results of combined analysis of variance for different traits in optimal conditions showed that the mean square, except for the % RWC traits in the limited conditions for plant height, head diameter, number of seeds per head, 1000-seeds weight, proline, catalase enzyme, superoxide dismutase enzyme, chlorophyll a, chlorophyll b, grain yield, and oil yield were significant. Results of data variance analysis indicated that the general combining ability for lines and tester was significant, as well as the specific combining ability (line x tester) for most traits. Based on the AGHK30 and AGHK44 combining ability, the RGHK25, RGHK50 and RGHK50 x AGHK56 and the RGHK56 x AGHK44 tester were identified as the most suitable line for the hybrid test in both conditions.

Abstract

As several reports of impacts arise due to the use of synthetic insecticides, the investigation for safer alternative insecticides should be continued. Using plant material that has several bioactivities is a promising way out to control insect pest. The objective of this study was to evaluate the effect of leaf and seed extract of Castanopsis megacarpa on mortality, longevity development and feeding preference of Crocidolomia pavonana larvae. Extraction conducted by infusion method. The bioassay assesment was carried out using the residual method. The concentration-mortality relationship was analyzed by probit. The antifeedant test was tested using choice and no-choice methods. Both extracts showed the same strong insecticidal activity, LC50 of 0.18% (leaf) and 0.12% (seed). Leaf and seed extracts at concentrations equivalent to LC50 and LC75 in both methods used showed consistent antifeedant properties. The antifeedant activity of extracts in the no-choice method at both concentrations showed a range of activities of 40.1%-53.7% (leaf) and 74.4%-82.7% (seed) extracts. The leaf and seed extracts of C. megacarpa did not significantly extend the larval development period. Plant material that has more than one bioactivity will be better for suppress the insect pest populations in the field.

Abstract

This study investigated the effect of betel (Piper betle L.) leaf at two physiological ages (young, 3rd leaf, and old, 8th leaf) at three concentrations of crude boiled-water extracts (10%, 20%, and 30%) against Streptococcus agalactiae and Escherichia coli. A completely randomized design with nesting was adopted for the six treatments and six replicates. The inhibition zone on nutrient agar media was measured. Overall there were no significantly differences. However, the inhibition zone diameters with 10%, 20%, and 30% crude water extracts of young leaves with S. agalactiae were 5.18 ± 0.99, 5.96 ± 0.34, and 6.38 ± 1.52 mm, respectively, and for old leaves, they were 5.76 ± 0.62, 5.67 ± 0.43, and 4.68 ± 0.33 mm, respectively. For E. coli, the corresponding values for young leaves were 3.96 ± 1.45, 4.54 ± 0.72, and 3.51 ± 0.48 mm, respectively, and for old leaves, the values were 3.85 ± 1.20, 4.14 ±0.68, and 2.35 ± 0.83 mm, respectively. The strongest inhibition was shown by the 30% crude water extract of young leaves against S. agalactiae.

Abstract

This research project was undertaken to study salinity stress changes in the nutritional quality of wheat genotypes. Four wheat genotypes SARC-1, SARC-5, SARC-7, and SARC-8 were grown under nonsaline and saline (7.5 dS/m and 15 dS/m) treatments. Salinity was created artificially by the addition of NaCl in soil before filling in pots. Recommended fertilizers N (120 kg/ha), P (100 kg/ha) and K (60 kg/ha) were used in the form of Urea, diammonium phosphate (DAP) and sulphate of potash (SOP) in both saline and non-saline treatments. The grains of wheat genotypes were evaluated for nutritional quality i.e. chemical composition, mineral contents, wet and dry gluten, gliadin and glutenin, and SDS-sedimentation value. The results showed that growth parameters (biological yield, number of grains, thousand grain weight, grain yield and grain length) were affected significantly by salinity stress. Protein contents were increased with salinity, whereas other parameters (moisture, ash, fat, fiber, glutenin, and SDS-Sedimentation value) were decreased by increasing salinity stress. Similarly, Na content increased while K, Ca, P, Fe, Mg and Zn decreased significantly by increasing salinity stress. Salinity stress affect positively on protein contents in grain of all wheat genotypes. SARC-7 and SARC-5 performed better than SARC-1 and SARC-8.

Abstract

A series of studies was carried out to explore the possibility of beetroot cultivation in the tropics on highlands.  This was initiated by a study on the effect of temperature and duration of beetroot storage on betacyanin content after determination of a wavelength giving the maximum absorbance of betacyanin extracts from beetroots.  The second study was designed to examine the response of betacyanin and plant growth to nitrogen (N) fertilization.  A randomized block design was used to impose the treatment of N fertilizer (Urea) consisting of 0, 0.15, 0.30, 0.45, and 0.60 g N per plant with five replicates.  The maximum absorbance of betacyanin extracts from fresh beetroots was attained at the wavelength of 536 nm.  Betacyanin content of beetroots increased with duration of storage up to 7 days from 229 ml l-1 to 639 ml l-1 when stored at room temperature (± 220C), and was reduced after slight increases when stored at lower temperatures.  Nitrogen fertilization reduced betacyanin content of beetroots with a reduction of up to 25%, from 351.5 to 257.6 ml l-1, with the application of 0.6 g N plant-1.  Root yield and total dry weight (TDW) increased with the supply of N fertilizer.

Abstract

To facilitate international discussion and research on the REDD+ framework and associated programs, I present an overview of the historical background, major rules, and challenges of implementing REDD+. The framework of REDD+ is illustrated using examples from scientific literature and the agreements adopted by the United Nations Framework Convention on Climate Change (UNFCCC). The institutional challenges related to REDD+ are discussed in the context of how to promote and implement REDD+ activities. Key issues for advancing REDD+ in the future include the establishment of a financial framework, the transferability of results, the risk of double counting, the timing of payments, and the domestic distribution of funds. Because agreements related to REDD+ do not mention transfers or trade of results from REDD+ activities, the transfer of results might give disincentives to developing countries; thus, allowing transfers or trade may actually limit REDD+ activities. Therefore, it seems preferable that the results of reduced emissions and increased removals through REDD+ activities, through publicly financed programs under the UNFCCC and Green Climate Fund (GCF), should be non-transferable. The transferability of results through REDD+ activities is important to consider, especially for different schemes such as the Forest Carbon Partnership Facility (FCPF) and the Joint Crediting Mechanism (JCM), because double counting can occur between countries and between schemes. Although I support advance performance-based payments for the planning and implementation of REDD+ activities, which is a similar concept to that discussed by the GCF, appropriate indicators and transparent methods for monitoring and evaluating performance will be required.

Abstract

This study aimed to determine the effects of chicken compost and KCl fertilizer application on the growth, yield, post-harvest quality of sweet corn (Zea mays L. var. saccharata), soil respiration and microbial population. The research was arranged according to a Factorial Random-Block Design consisting of two factors and three replications. The first factor was the dose of chicken compost (0 and 15 t/ha) and the second the dose of KCl fertilizer (0, 50, 100 and 150 kg/ha). The results showed that chicken compost stimulated the growth, yield, postharvest quality of sweet corn, respiration, and microbial activity of soil. KCl fertilizer increased SPAD values linearly and quadratically chlorophyll pigment, β-carotene, yield components, and yield. KCl fertilizer did not affect soil respiration, fungi, or bacteria populations. The use of chicken compost reduced the need for KCl fertilization by 25%. Therefore, the integration of organic and inorganic fertilizers are recommended to be applied by farmers in the tropics.

Abstract

The study aims to evaluate the effectiveness of sweet basil aqueous extract against Sclerotium rolfsii in-vitro and damping-off on tomato seedling in-vivo. The sweet basil leaves were obtained from a commercial market in Los Banos, Philippines. The leaves were rinsed by water and then air dried. The dried leaves were ground using a domestic blender and 10 grams of this material was extracted using 100 ml of sterile distilled water (1:10 w/v) and 0.01 ml absolute methanol. The mixture was kept for 48 hours at room temperature. The solution was strained by a Whatman filter paper No. 1, then the extract was stored at 4°C. The effectiveness of sweet basil extract was determined in-vitro by measuring the mycelial growth inhibition of S.rolfsii and in-vivo by the percentage of disease incidence on tomato seedlings. The result showed that sweet basil extract was effective to inhibit the mycelial growth (33.35%). However, the effectiveness of water extract of sweet basil was considered ineffective for reducing disease incidence on the inoculated tomato seedlings, i.e. 46.67%-60%, similar to benomyl after the inoculation. Further investigation is needed to find out an effective formula of O. basilicum leaf extract which is stable and prolonged persistence for controlling S. rolfsii.

Abstract

Cacao pod rot caused by Phytophthora palmivora, is an important disease and contributes significant disease losses to global cocoa production. This research objective was to determine the effect of Trichoderma harzianum and T. virens suspensions to cacao pod rot disease on the field. This research was carried out in Pulo Hagu village, Pidie Regency, Aceh, Indonesia from March to July 2017. The single pattern randomized block design was adopted to evaluate three treatments, i.e. without suspension (control), suspensions of T. Harzianum, and T. virens for eight replications. Each replication consisted of three of experimental units. The result showed that both of Trichoderma species contained only Alkaloid metabolite based on Phytochemical test. On the field, the application of T. harzianum suspension reduced the percentage of fruit infection and disease intensity for 48.57 %, 46.04 % at 12 weeks after application (WAA) respectively. Based on the percentage reduction in the area of the spot between the metabolites T. harzianum suspension and control and T. virens and control are 47.24 % and 27.46 % at 87 WAA respectively. In addition, T. virens suppressed the percentage of infected fruit and the intensity of infected fruit for 40.61 % and 38.02 % at 12 WAA.
