Abstract

Termites are plants, housing, furniture, and building pests. Termite control has been carried out using synthetic pesticides that are harmful to the environment and human health. Innovation in controlling termites and fungi is required for the preservation of wood and furniture. The aim of this study was to analyze the use of bamboo Wulung’s (Gigochocha atroviolace) smoke for controlling termites and fungi attacks. The methods used were the manufacture of bamboo’s smoke, a test of preference for termites, and mortality of termites. The results showed that liquid smoke at 450oC was effective for controlling termites and fungi. The smoke of bamboo Wulung with a concentration of 10% can control C. formosanus termites. It showed 100% mortality within 14 days, while the smoke of bamboo Wulung with a concentration of 5% showed 100% mortality of R. speratus within 14 days. Bamboo smoke at pyrolysis temperature 450oC and a concentration of 2.0% can prevent the growth of T. vesicolor fungus while effective at the same concentration for F. palustris. Bamboo smoke can prevent the growth of T. vesicolor mushrooms at a liquid smoke temperature of 450oC with a concentration of 2% and the fungus F. palustris at a concentration of 2.0%.

Abstract

Oil palm empty fruit bunches (OPEFB) were utilized as the source of organic fertilizer, but become a medium of Oryctes rhinoceros proliferation in oil palm plantations. O. rhinoceros uses cellulose, hemicellulose and lignin in the OPEFB as energy sources for larvae growth and development. In the process of breaking and combining complex compounds into simple molecules, they are establishing symbiotic relationship with bacteria residing in the digestive tract of O. rhinoceros larvae. Isolation of the symbiotic bacteria of the O. rhinoceros larvae was carried out with the aim of identifying bacteria in the digestive tract of the third instar found in the OPEFB. This research was done by using a descriptive method. Exploration of symbiotic bacteria of O. rhinoceros larvae was conducted through two stages. The first step was attained by isolating, growing and multiplying the bacteria and conducting biochemical testing. The second phase was accomplished by molecular testing for bacterial identification. The results showed that bacterial isolates were found and and after molecularly sequenced based on 6S rDNA, the species were identified as Bacillus stratosphericus, B. siamensis, B. cereus, Haemophilus parainfluenzae, Achromobacter xylosoxidans, and Alcaligenes faecalis. The research also found several species of bacteria originating from the hindgut larvae O. rhinoceros.

Abstract

Flax is a crop whose products can be used in a variety of ways such as industrial use, human consumption, and fiber production. Nitrogen appears to have a positive effect on flaxseed growth and production. In an experiment conducted in two consecutive years in Greece, it has been studied how three combinations of urea fertilization affect flaxseed cultivation (cv. ‘Everest’). More specifically, the experimental treatments with urea fertilizers were represented as follows: only urea; urea with urease inhibitor; and urea with urease inhibitor and nitrates inhibitors. The value of root mass ranged from 0.780 to 1.182 mg/cm3 in the first year and from 0.872 to 1.267 mg/cm3 in the second year. The maximum value of plant height was 69.25 in urea with double inhibitors. Leaf Area Index (LAI) was double in fertilized plots compare to unfertilized. Oil content was significantly affected by year and noticed mostly 1% among treatments. Oil yield was affected by fertilizers and the maximum value was 513.96 kg/ha. A positive significant correlation coefficient was observed between oil yield and LAI (r=0.8699). A positive correlation was noticed between seed yield and NUE (r=0.6881). The most beneficial effects were mentioned under urea with UI and NI inhibitors.

Abstract

Agriculture cultivation systems and farmer’s income are the crucial issues in many agriculture-based developing countries. Our previous study proved that the polyculture system positively affects land productivity and land-use efficiency. This research investigated the relationship between intercropping farming systems and farmer’s income. We hypothesized that the intercropping farming system increases farmer’s income compared to monoculture. The farming income analysis was carried out using Microsoft Excel and STATA software. The results showed that the farmer’s income derived from the intercropping farming system differs from monoculture. Based on the T-test, the intercropping farming system provided a higher income. Intercropping farming systems that have higher plant diversity, contributed to higher farmer income from different plant yields. Farmers that applied the intercropping system would harvest of 2-3 different plants from one cultivated land at the same time with regular planting distance. These indicated that the intercropping farming system reduces the risk of loss due to price fluctuations of products and the higher input costs during the production process.

Abstract

Genetic diversity is required for crop improvement against environmental stress. Astudy wasconducted to determine characters as selection indicators of water-stress tolerance, and of yield components and yield. The research method involved a one-factor experiment with 21 sweet potato clones, using a Completely Randomized Block design with three replicates. Water stress in this study mean that the bottom of plants was submerged in water at 2 and 3 months of age. Determination of selection indicators was conducted by estimating the coefficients of genetic and phenotypic variations, heritabilities, genetic advance and correlation test result. The characters of number of leaves, individual leaf area, leaf area per plant, leaf area index, stem length, internode length, number of tubers (storage root), individual tuber weight and yieldas selection indicators of water stress tolerance. Selection indicators of yield components consisted of less number of leaves, small leaf size, short stemsand number of branches, whereas selection indicators of yield were small leaf size, number of branches, number of tubers and individual tuber weight. Selection became effective and efficient when the selection indicators were influenced greatly by genetic factors.

Abstract

Siam orange (Citrus nobilis L.) provides great economic value and social importance, despite its susceptibility to Huanglongbing (HLB) disease caused by Ca. Liberabacter sp., classified as specific bacterium phloem vessels marked by the formation of callouses covering plasmodesmata. This research aims to improve the tolerance of Siam orange from Banyuwangi (SB) to HLB disease. The experiment was undertaken by performing a randomized design (CRD) with one factor (irradiation dose). This study consists of two interrelated experiments, which include: induction of embryo mutations with gamma rays irradiation, and in vitro selection of putative mutant. The embryo of SB was irradiated by gamma rays with doses of 0, 45, 50, and 55 Gray. Each treatment was repeatedly undertaken for five times with 20 embryos. After 24 weeks, in vitro selection of putative mutant shoots was screened by HLB pathogen suspension. The observation indicated that treatment of gamma rays in various doses influenced embryo germination. In general, gamma ray irradiation gave significant effects on embryo germination and plant morphological characters. In vitro selection results for putative mutant on doses of 45, 50, and 55 indicated tolerance to HLB pathogen after selection.

Abstract

Bawang dayak is a medicinal plant and can be grown as an economical crop with great potential value. Its contains secondary metabolites with biological activities that are important for human health. The main problem related with the production of bawang dayak is the standard of cultivation. The goal of the experiment was to study the effects of organic fertilizers and growing media on the growth and yield of bawang dayak. The polybag experiment was performed with two factors, namely soil type and organic fertilizer by Factorial Completely Randomized Design and located in the greenhouse of University of Palangka Raya. The treatments were chicken manure, oil palm empty-fruit-bunch compost (OPEFBC), and NASA granule as organic fertilizers, while Histosol and Ultisol served as growing media treatment. The results showed that OPEFBC gave the highest in Ultisol and chicken manure in Histosol to improve plant height. The highest number of tubers were developed in Ultisol. Chicken manure improved P and Fe bulbs tissue whereas the content of N and K bulbs grown in Ultisol was higher than those in Histosol.

Abstract

The use of pesticides in fresh food of plant origin (FFPO) such as horticulture products is widely known. Such broad implementation of pesticide can result in a tremendous usage of pesticides and, afterward, in intolerable levels of pesticide residues in the products. In this work, we analyzed the pesticide residues in FFPO - which include fruits, vegetables, and rice - from some provinces in Indonesia. These products are taken from the market as samples for this analysis and they were not washed before the test. The test for pesticide residues uses two kinds of tests, which are: Rapid Test Kit that gives the qualitative result (presence or absence of active ingredients residual) without showing the amount of pesticide residue itself; and laboratory test that gives a quantitative result of pesticide active ingredients residual. Lab test data analysis shows that 98.58% of total samples from 26 provinces do not contain or have residues under MRLs so that it is stated as achieving food safety requirements. The pesticide residues include Organophosphate, Carbamate, Pyrethroid, Organochlorine, N-Phenylpyrazole, and Neonicotinoid groups of pesticide. Considering the effect of pesticide (residue) on human health and to environmental sustainability, efforts to control pesticide use need to be continued.

Abstract

Leaf canopy area is a fundamental crop growth characteristic that encompasses the spatial area covered by plants. However, non-destructive and automatic computation of lettuce canopy area is still open research. This study presents a vision-based system with color space thresholding and machine learning models in measuring the photosynthetic productivity of aquaponic lettuce based on canopy area derived from the numerical image textural features of Haralick and gray level co-occurrence matrix (GLCM). Lettuce images on different growth stages with varying photosynthetic pigment intensities and geometrical structures are extracted with contrast, correlation, energy, homogeneity, entropy, variance, and information measure of correlations 1 and 2 features. For multi-band color space thresholding, CIELab bested RGB, HSV, and YCbCr colour spaces in segmenting the lettuce plant with sensitivity and specificity measures of 94.77% and 97.16% respectively. For measuring the lettuce canopy area, RMSE was recorded as 50.23% for fitness function neural network (FFNN), 20.46% for radial basis function neural network (RBFNN), 15.11% for exact radial basic function neural network (RBEFNN) and 13.54% for generalized regression neural network (GRNN). Comparative analysis revealed that the two-hidden layer GRNN model with 0.09 spread value and 240 hidden neurons bested other machine learning models in terms of RMSE without overfitting.

Abstract

In recent years, intensified development of stem rust of wheat has again been noted in the grain-growing regions of Kazakhstan. To determine the genetic basis of immunity in 2015 – 2019, the authors performed targeted studies in the conditions of the southeast and north of Kazakhstan on the natural and the artificially infectious backgrounds of inoculation. Their scientific novelty consisted in identifying effective Sr genes of wheat resistance to the Kazakhstan population of stem rust. The obtained results of the immunological assessment of the trap varieties show that most studied genotypes with the Sr genes were susceptible to the Kazakhstan population of stem rust. With that, the varieties carrying the Sr31 gene have been affected to varying degrees. It should be especially noted that the Sr31 gene in combination with the Sr24 gene ensured more reliable protection from the population of the stem rust pathogen. The authors have selected the obtained resistance genes by their efficiency: Sr2 complex; Sr11; Sr21; Sr31; Sr36; Sr39; Sr40, SrSatu; SrNin, as well as combinations of the Sr24 and 1RS-Am genes; Sr24.31; Sr6.31.21; Sr6,24,36,1RSAm; Sr7a, Sr12, Sr6; and Sr31 absent. The authors recommend them as sources of resistance to the local stem rust population.
