Abstract

The research aims to obtain a genotype of local glutinous rice tolerant to drought stress by investigating yield and physiological responses. The experiment is conducted in May-September 2020 in West Lombok, West Nusa Tenggara. The factorial experiment uses a Randomized Block Design, including the first factor: glutinous rice varieties, namely Me'e, Kala, Samada, and Paketih. The second factor is water supply, consisting of 2,250 ml, 3,375 ml, 4,500 ml, and 5,625 ml. The variables are observed stomata density, the content of proline and chlorophyll, panicle length, number and weight of grains, starch, and amylose content. The result shows that the stomata density has about 39 to 54.74 mm2 caused by water application on all glutinous rice strains. The chlorophyll content decreases to 50% following the declining amount of water application, while proline content on all varieties reaches 40% by water supply at 2,250 ml. In addition, the amylose content reaches 40% with 4,500 ml of water and 5,625 ml of water in all varieties. By contrast, increasing the amount in water supply affect several variables observed, an increase in panicle length of around 10% and the number and weight of the grains at 20% and 40%, respectively.

Abstract

Lanzones scale insect (LSI) has been an important insect pest of lanzones since its first record in 2004. It causes massive defoliation on trees which eventually results to underdeveloped and sour fruits. Different lanzones-growing areas in the Philippines were surveyed for LSI along with its associated parasitoids in commercial lanzones farms located in Laguna (Los Baños,Nagcarlan and Sta. Maria), Oriental Mindoro (Villa Cerveza, Villa Cerveza, San Gabriel-Alcate), Negros (Abante-Pamplona, Poblacion - Pamplona,  Lunga, Valencia, Talisay - Negros Occidental, Jawa-Valencia, Lunga-Valencia, Bongbong), Misamis Occidental (Aloran - Misamis Occidental, Calamba, Oroquieta, Sapang Dalaga, Plaridel), Camiguin (Catarman, Poblacion, Sagay, Tagdo, Mahinog), North Cotabato (Makilala, Kidapawan, and Kabacan) and Sulu (Maimbung, Patikol,Talipao).  From each collection site, a total of 10 infested trees were sampled at random with leaflets (N=10) collected in four cardinal directions around canopy. Leaflets were scanned, photographed, and transported to the laboratory. Population estimates of each local population was obtained along with demographic structure viz. age structure and male-female sex ratio. The sample per tree were kept individually in customized cages for parasitoid emergence and determination of parasitization rate. Parasitoids were identified as Aphytis sp., Encarsia sp. and 2 other unidentified species. LSI population and percent parasitism in Laguna were quite high compared to North Cotabato. Results of this study will contribute to the basic knowledge needed to improve control strategy on LSI.

Abstract

Bemisia tabaci is a major pest in chili as it can act as a vector for transmitting the yellow curl virus. Endophytic bacteria have been reported to trigger plant defense against whiteflies. This study aimed to obtain a solid formula for the endophytic bacteria B. pseudomycoides strain SLBE1.1SN and a storage duration that effectively controls whitefly. This experimental study used a completely randomized design (CRD) consisting of 26 treatments and repeated three times. The treatments combined different types of endophytic bacterial carrier formulas and storage duration, synthetic insecticide treatment (Imidacloprid), and control. The treatments were applied to chili seeds and seedlings. The results showed that not all stored endophytic bacterial formulation could suppress the whitefly population on chili plants. The formula B. pseudomycoides strain SLBE1.1SN with rice straw as carrier material at six weeks storage was the best formula for controlling whitefly. This suggests that the formulation of stored endophytic bacteria not only reduced the number of eggs laid, but also suppressed the development of nymphs and imago.

Abstract

Plant age plays a crucial role in determining rice yield. The study on the prediction model of spatially specific rice plant age was still less reported, especially that based on high spatial resolution multispectral data. This study investigates the use of Geographic Weighted Regression (GWR) and extracted vegetation indexes (VI) from the Sentinel-2 multispectral image to build the prediction model based on the time-series dataset from the paddy field observation station. The GWR result was also compared to the Linear Regression (LR) model to demonstrate the impact of including spatial attribute into the prediction model. Since the majority of paddy field observation stations are situated on Java Island, it served as the research location for this investigation. The results indicate that VI from the Sentinel-2 image shows a significant correlation with the age of the paddy, then the VI was able to use as a predictor to build the paddy age prediction model. In the statistical evaluation of the model, the coefficient of determination values (R2) reached 0.65, and the RMSE of estimate value was 15 days.

Abstract

The assessment of genetic diversity is crucial in citrus improvement programs that represents the relationship among genotypes, thus determining an effective plant breeding program. A molecular assessment of 52 collected citrus accessions based on ISSR and SSR was conducted at the ICSFRI in 2020. Based on 4 ISSR primers and 3 SSR primers, the citrus genotypes were grouped into 6 major clusters. Cluster I has the largest 25 members, while Cluster II, III, IV, V and VI have 5, 2, 2, 4 and 13 accession members, respectively. Members of Cluster I are the majority in the mandarin type with spheroids fruit shape with truncate on the fruit top. Cluster II contains citrus accessions from naturally occurring hybrids, while orange accession members of Cluster III are originally grown in different climates. Cluster IV and V members are connected to a common ancestor, Citrus aurantifolia and Citrus limonia. At the same time, Cluster VI is a pumelo group that contains members of Citrus maxima. Clustering based on molecular markers (ISSR and SSR) resulting in this study is useful in citrus breeding programs in Indonesia and other countries. The genetic distance of the parents affects the heterosis effect of the progeny.

Abstract

This study aimed at determining the effect of Arbuscular Mycorrhizal Fungi (AMF) and Antagonistic Rhizosphere Fungi (ARF) on growth of Coffea liberica seedlings in peat soils. Eight AMF isolates (without AMF, Glomus sp.-1a, Glomus sp.-3c, Acaulospora sp.-1b, Acaulospora sp.- 2d, Glomus sp.-1a + Glomus sp.-3c, Acaulospora sp.-1b + Acaulospora sp.-2d, and mixtures of Glomus sp.-1a + Glomus sp.-3c + Acaulospora sp.-1b + Acaulospora sp.-2d) were combined with five ARF types (without ARF, Trichoderma sp., Aspergillus sp., Gliocladium sp., and Penicillium sp.). Data were collected on the following variables: seedling height, leaf number, stem diameter, shoot and root dry weight, N and P uptake, and root infection by AMF. Results indicated that Trichoderma sp., in combination with various types of AMF, was the best ARF in promoting C. liberica seedling growth and increasing N and P uptake. On the other hand, the mixture of Glomus sp.-1a + Glomus sp.-3c combined with various types of ARF was the best AMF in promoting seedling growth and increasing N and P uptake. It can be concluded that Trichoderma sp. and the mixture of Glomus sp-1a and Glomus sp-3c were best combination to be applied to promote the C. liberica seedlings grown in peat soil.

Abstract

The low productivity of shallot ‘Bima Brebes’ during the rainy season contributed to increasing Indonesia's economic inflation. This study aimed to assess the sustainability of shallot cultivation in low-organic sandy clay soil during the rainy season in South Sumatera, Indonesia. The study observed the farmer group's actual shallot cultivation method. The research findings were expected to explain the phenomenon of shallot production (Cohen f2) at least 0.50 with a maximum error rate (α) of 0.05 and a probability of making the right decisions (1-β) at least 80%. The variables included climate, soil characteristics, cultivation methods carried out by farmers, plant growth, and shallot production. The cultivated field has sufficient porosity to drain water quickly. Still, it tends to make compaction easier. The diameter of the shallot bulb produced fell into category 1 (size over 2.5 cm) by as much as 31.0%, category 2 (between 2.0-2.5 cm) by 38.0%, and category 3 (between 1.5-2.0 cm) by 17.8%. The loss caused by Fusarium disease was 20.29%. Sustainability of low disease-resistance shallot variety cultivation in low-carbon sandy clay soil during rainy seasons was possible by regulating soil humidity rather than fungicide application.

Abstract

The tomato (Solanum lycopersicum) is considered a significant horticultural crop in Indonesia and is widely consumed by the local population. It should be cultivated by more efficient water irrigation methods, such as pocket fertigation. This study aims to determine the effect of pocket fertigation-based nitrogen fertilizer treatment on the growth and yield of tomato plants. Three different treatments of fertilizers, including without chemical fertilizer as control (P0), 200 kg/ha of urea fertilizer (P1), and 200 kg/ha of ZA fertilizer (P2), are applied by utilizing pocket fertigation. The tomato plant is cultivated under 24-30oC of daily air temperature, 25.6-28.9oC of soil temperature, and 68-201 W/m² of solar radiation recorded by an automatic weather station. The results show that treatments do not significantly affectplant height, number of branches, root volume, number of fruits, fruit weight per plant, fruit color index, fruit hardness, Brix, and consumption index. However, P1 increases yield and fruit quality more efficiently, while P2effectively increases plant weight. Further research needs to regard the optimal dosage of Ureaand ZA in optimizing the yield and quality of fruits.

Abstract

The rising popularity of the Sissoo spinach is growing in the vegetable industry along with the increase in its demand. However, water stress conditions may affect the plants' growth, physiology, and water status. Hence, the research study aims to evaluate Sissoo spinach's growth, physiological parameters, and water status once subjected to water deficit. Besides, it also focuses on determining the optimum water requirement for Sissoo spinach. There were four different water treatments consisting of 100% (well-watered), 75% (moderate water deficit), 50% (high water deficit), and 25% (severe water deficit) water treatments arranged in Randomized Complete Block Design (RCBD) with five replications in the greenhouse. The research findings show that the results are statistically significant for most parameters: plant height, number of leaves, chlorophyll content, stomatal conductances, plant water status, and chlorophyll fluorescence. Contrarily, the stem diameter, fresh weight, dry weight, and leaf area data do not show any significant differences. As it comes to the point of research findings, the optimum water requirement for Sissoo spinach was 50% water treatment. This is crucial to prevent unnecessary, avoidable water application onto plants.

Abstract

The garlic seed bulbs cannot be planted immediately after harvest because has dormant period. Bulb dormancy can be broken by exposure of pre-planting bulbs to low temperatures. The research aimed to determine the sensitivity of different bolting types of garlic genotypes at low temperatures and the role of low temperatures on dormancy break. The experiment was conducted from March to June 2019 at the Universitas Brawijaya, using a nested design with three replications. Chinese hardneck and softneck, Sangga Sembalun and Tawangmangu Baru were the garlic accessions used in the study. The storage temperature treatments at 3 and 7°C; and room temperature at 27°C. Chinese softneck bulb had the highest sprouting and rooting after 3 and 7°C storage and was sensitive to low temperatures. The Chinese hardneck had the lowest sprouting and was highly insensitive to cold stress. Sangga Sembalun and Tawangmangu Baru had sprouted bulbs in between these Chinese genotypes, and they were insensitive and highly insensitive to low temperatures, respectively. Metabolites of 5-hydroxymethyl-2-furancarboxaldehyde, palmitic acid, diallyl trisulfide, and 2,3-dihydro-3,5-dihydroxy-6-methyl-4(H)-pyran-4-one played important roles in the bulb response to low temperature stress and directly or indirectly involved in the sprouting and rooting in dormant garlic cloves.
