Abstract

Despite being one of the most important staple food consumed by more than half of the world population, the development of red rice still lacks behind the regular white rice. In Madura, most farmers still use their local landraces with red pericarp. Since most of the growing season is dependent on rainfall, those landraces are expected to provide some useful genes related to drought tolerance. This research aimed to select drought-tolerant accessions candidates of red rice derived from pure lines selection at early stages using PEG 6000. A randomized complete block design was used with two factors and three replications, the first factor was red rice genotype and the second factor was two levels of PEG 6000 concentration (0% and 25%). The results showed that there were different responses in all genotypes used in terms of their responses to PEG 6000 screening. Seedling length, seminal root length, shoot length, seminal root dry weight, and shoot dry weight were reduced by the application of PEG 6000 compared to non-PEG 6000 media. Two genotypes had a better response to PEG 6000 treatment compared to check tolerant (Salumpikit), and these are expected to become a valuable resources for further breeding activities.

Abstract

Avocado cv. Cipedak is a superior cultivar that match the preferences of Indonesian consumers. However, it has several weaknesses, such as low edible portion, thin skin, and short fruit shelf life. One effort to improve the character weakness is by mutation breeding using gamma ray irradiation. Induction of mutation by gamma ray irradiation at a dose of 10 Gy was conducted on Cipedak avocado shoots in October 2021 which produced 13 first generation avocado mutants (M1). Observation on leaves morphological characters and DNA analysis were needed to find out the changes level of genetical diversity. The research was conducted in Cukurgondang Research Station and Molecular Laboratory of Indonesian Tropical Fruits Research Institute from January to March 2022. The plant material used involved 13 M1 progenies and cv. Cipedak. The material used were 20 weeks old grafted plants. The observed variables were macro and micromorphological characters as well as DNA-RAPD analysis. The results showed that there were phenotypic and genotypic changes in 13 M1 avocados seedlings. The coefficients of differences on macro and micromorphological characters were up to 33% and 28%, respectively and the coefficient of difference for DNA-RAPD analysis was 74%.

Abstract

Katokkon pepper plant is originated from Toraja, South Sulawesi, Indonesia. This endemic pepper variety has unique hot and spicy characters with a distinctive bell pepper aroma, and aesthetic shape similar to paprika, but with smaller size. This research was conducted to identify ploidy level and plant morphology of colchicine induced Katokkon pepper at Laboratory of Plant Reproduction Bioscience and Biotechnology, Department of Agronomy, Faculty of Agriculture, Universitas Hasanuddin and experimental field of Agricultural Extension System Vocational High School Santo Paulus Tana Toraja (S 03°04’177” E 119°51’526”). Two weeks old seedlings were immersed for 4.5 hours in colchicine concentration (0.00%, 0.0125%, 0.025%, 0.05% and 0.10%). Flow cytometry analysis was carried out using Partec Cy-Flow SpaceTM. Result showed that colchicine concentration (0.025%, 0.05% and 0.1%) produced mixoploid plants with two set of chromosomes (2n=24, 4n=48). This study also found morphological differences between mixoploids plants induced by 0.025%, 0.05% and 0.1% colchicine and diploid plants (0% and 0.0125% colchicine) during first two juvenile leaves phase. However, this difference did not occur further, and eventually morphology of adult mixoploid plant was not significantly different from control (diploid), which concurred to grading mixoploid grade 2. The mixoploid plants analyzed consist of higher diploids cells than tetraploid.

Abstract

The functional roles of Arbuscular Mycorrhiza (AM) in soils with P limitations are well documented. However, the protocol to produce effective AM inocula was still limited. This research aims at obtaining the effective AM culture in handling P constraints for maize growth on Andisols. The first experiment of pot culture I was to propagate and examine the effectiveness of AM isolates by using a factorial completely randomized design with two factors, A=media (A0: zeolite; A1: representative media=Andisol Tengaran; A2: typical media=a mixture of Andisol Tengaran+Tawangmangu; A3: typical media+Bio-RP nutrition; A4: Inceptisol) and I = AM inoculum source (I0: no inoculum; I1: AM from Andisol Tengaran; I2: AM from Andisol Tengaran + Tawangmangu; I3: AM from 8 soil types), with six replications. The second experiment investigated the consistency of mycorrhizal effectiveness by reculturing AM cultures generation I to pot cultures generation II with the same composition of the respective media. The combination treatments of A1I3, A2I2, A0I3, and A4I3 (AM cultures generation I), continued by A1I32, A2I22, A0I32, and A4I32 (AM cultures generation II) showed consistently the highest AM infectivity and effectiveness on maize growth and P uptake on Andisol-based media, and on the comparison media of zeolite and Inceptisol media, respectively.

Abstract

Land and water resources, climate change, and disaster risks significantly affect the agricultural sector. An effective solution for growing crops to improve productivity and optimize the use of resources is through controlled-environment agriculture (CEA). Evapotranspiration (ET) is an important greenhouse crop attribute that can be optimized for optimum plant growth. Light intensity and radiation are significant for controlling ET. To address this challenge, this study successfully determined the properties of optimum artificial light for minimum evapotranspiration rate of head development-stage and harvest-stage lettuce under light-period and dark-period using genetic programming and bio-inspired algorithms namely, grey wolf optimization (GWO), whale optimization algorithm (WOA), dragonfly algorithm (DA), and moth flame optimization (MFO). MFO provided the optimized global solution for the configured models. Results showed that head development-stage lettuce requires higher light intensity with lower visible to infrared radiation ratio (Vis/IR) than harvest-stage lettuce when exposed to light. On the other hand, harvest-stage lettuce requires higher light intensity with lower Vis/IR than head development-stage under dark-period respiration reaction. Findings of this study can be utilized in growing and improving yield crops in controlled-environment agriculture.

Abstract

Improving the grain yield of rice and increasing the availability of nutrients in cultivated soils are important goals of sustainable agriculture. This study was aimed to determine the effects of different fertilizer applications and dolomite amendments on rice yield, quality, and soil fertility after plantation in post-active acid sulfate soil in the Phra Nakhon Si Ayutthaya province, Thailand. A randomized complete block design (RCBD) with six treatments and three replications was employed, i.e. T1 (no fertilizer); T2 (fertilizer at the rate of the farmers’ practice, CFFMP); T3 (fertilizer at the rate of site-specific nutrient management, SSNM); T4 (SSNM+organic fertilizer, OF); T5 (SSNM+dolomite, DM); and T6 (SSNM+OF0.5+DM0.5). Our results indicated that the treatment of SSNM+DM provided the highest grain yield (6,171 kg/ha). For the quality of rice grain, the highest protein level was found in the treatment of CFFMP (80.2 g/kg). Application of fertilizer according to the SSNM+OF treatment resulted in higher soil organic matter, available phosphorus, and exchangeable potassium in the soil after rice cultivation than in other treatments. The results suggested that the application of SSNM+DM and SSNM +OF0.5+DM0.5 was the best options for improving rice yield in this area.

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.
