Abstract

Monitoring rice plant growth is crucial for evaluating rice field management and yield production. RGB images are generated from Unmanned Aerial Vehicles (UAV) with RGB cameras. UAVs produce high spatial and temporal resolution, while RGB cameras are commonly used and cheap. The objectives of this study were to identify the spectral pattern of rice plant growth and to estimate yield production based on the spectral value of RGB images. The spectral pattern and yield estimation were analyzed using confidence interval (CI) and regression, respectively. Results show that spectral pattern during the vegetative until ripening stage forms a concave with minimum value in the generative stage and decreases towards the harvest stage. Based on the CI value, the high interval between upper and lower happened in the vegetative and ripening stages while the low interval happened in the generative stage. The high CI in the vegetative and ripening stages was due to the soil background and complexity of the rice plant canopy, respectively while the low CI in the generative stage was due to the homogeneous response of the leaf canopy. The best rice yield estimation based on the spectral value occurs in the ripening stage with an R2 of 0.84. Keywords: chlorophyll content, confidence interval, drone images, rice plant, regression

Abstract

Trichoderma has become one of the most studied filamentous fungi to be used as a greener and more sustainable solution for improving the production and growth of numerous crops, due to its capability to form symbiotic associations with plants. This study aimed to evaluate the effect of Trichoderma isolates obtained from the rhizosphere of organic rice fields in Sukabumi, Indonesia, in enhancing rice germination and seedling growth. A laboratory experiment used a completely randomized design consisting of seed treatments of 21 Trichoderma isolates (T1-T21) and a control treatment without Trichoderma (C). The inoculation was employed to elucidate any potential effects of Trichoderma isolates. Results showed that five isolates, i.e., T5, T7, T9, T10, and T14 stimulated the highest seedling vigor index, root and shoot length, and fresh weight and dry weight. These findings exhibited the potential of these five isolates as plant growth-promoting fungi to improve rice seedling growth and contribute to our understanding of the role of symbiotic fungi in sustainable rice crop production. Keywords: plant growth promoting fungi; seed treatment; plant-microbe interactions, symbiotic fungi

Abstract

A superior variety of rice with high yield and resistance to diseases is expected to meet the increasing demand for this one of the most important carbohydrate sources worldwide. Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the major biotic stresses limiting rice production. Combining BLB resistance and high-yield traits is possible through gene pyramiding. Introgression of targeted traits in the parental genotypes and hybridity confirmation in the F1 generation are important initial steps in gene pyramiding. This study aimed to confirm the presence of targeted genes in parent genotypes using specific molecular markers and to confirm the hybridity of F1 plants generated from three crosses combinations of Inpari 32 (as the female parent) and three Code-qTSN4 lines (as the male parents) using SSR markers. This study successfully confirmed the introgression of BLB-resistance genes in Inpari 32 (Xa4, Xa7, and Xa21) and in Code-qTSN4 (Xa4, Xa7). The introgression of yield-related QTL, qTSN4, was confirmed in the three Code-qTSN4 lines (A10-1, B12-2, and A16-5) by RM17483 marker. Five SSR markers (RM5, RM55, RM105, RM223, and RM561) successfully confirmed the hybridity of F1 derived from Inpari 32xA10-1 (five individuals), Inpari 32xB12-2 (one individual), Inpari 32xA16-5 (two individuals). These confirmed hybrids can be further evaluated in the F2 generation. Keywords: Gene pyramiding; molecular marker; SSR; qTSN4; Xoo.

Abstract

The seed yield production determines the success of the development of hybrid rice. Here, an effective and efficient cultivation technology for producing hybrid rice seeds is optimized through spacing and row ratio management. This study aimed to evaluate the effects of spacing and row ratio of restorer (R) : CMS (A) on F1 hybrid rice seed production. The experiment was conducted at the Indonesian Center of Rice Research's experimental field in the dry season of 2016, using parental lines HIPA18 hybrid rice, i.e., CMS: IR79156A line and Restorer: IR53942 line. The experiment was laid out in a strip-plot design replicated three times. Two factors were studied, i.e., plant spacing between CMS lines and row ratio R by A-lines. The results indicated that the highest HIPA18 seed production was obtained from 20 cm x 20 cm spacing of CMS with row ratio 2R:14A, i.e., 3.62 tons ha-1. Plant spacing and row ratio interactions were improved tillers number per plant of restorer and F1 seed yields. Keywords: A-lines; CMS; F1 hybrid rice; R-lines

Abstract

Amorphophallus muelleri Blume locally called Iles-iles or porang becomes a new commercial commodity in Indonesia. The tuber as the most economic value contains high glucomannan. It has been speculated that the high variation in production among farmers is due to different planting materials and soil organic carbon (SOC). Thus, the research aimed to evaluate the growth and yield of A. muelleri from different planting materials and levels of SOC. The research was carried out at Leuwikopo Experimental Station IPB Bogor from December 2021 to August 2022, using a nested design. The main plot was the level of SOC (2%, 3%, 4%, 6%), and the sub-plot was planting materials (seeds, bulbils, and tubers from leaf cuttings). The results showed SOC status determined growth and yield. Plant height, stem diameter, number of leaves, canopy width, leaf greenness, number of tubers, weight, and size of tubers, stomatal conductance, and intercellular CO2 were significantly affected by SOC level. SOC at a level of 6% stimulated the highest growth and yield. Planting materials also determined the growth and yield. Plants originating from bulbils produced the highest yields, followed by tuber from leaf cuttings, and seeds. It is recommended to plant bulbils accompanied by maintaining SOC at a level of 6%.

Abstract

Rapid multiplication of potato seed using cuttings is a pivotal strategy for ensuring seed availability. This study aimed to elucidate the interactive effects of node number, paclobutrazol concentration, and planting density on seed potato and cutting productions. The study consisted of two experiments. The first experiment evaluated two genotypes (Granola and PKHT-6) with one or two nodes per cutting. The second experiment investigated planting density (one, three, or five plants per polybag) and paclobutrazol concentration (0, 15, 30, and 45 mg L-1). Notably, node number did not significantly influence cutting success, despite genotype-specific and interactive effects on vegetative parameters like plant height, stem diameter, leaf number, and root length. Planting density had no statistically significant impact on all vegetative parameters but demonstrably affected all production parameters. Conversely, paclobutrazol concentration significantly affected all vegetative parameters and influenced all production parameters except tuber weight per plant. From the results of this research, the use of single cutting is more recommended because it will obtain more plant material compared to two-node cuttings. Thus, in a more global context of potato development, this has the potential to increase the production of potato seeds from cuttings twice as much as the current seed production. The use of three plants/polybags is more recommended since it will produce more tuber but not different with five plants, and the use of paclobutrazol 15 mg L-1 is also recommended to increase the number of tubers. In this way, the production costs of G0 potato seeds can be reduced so that the availability of G0 potato seeds will be more guaranteed and affordable.

Abstract

West Aceh Regency is one of the regions in Indonesia with quite extensive peatlands, but the diversity of food crop commodities is still very low. To enhance food diversification programs of rice, sorghum production is important. The purpose of this research was to test several varieties of sorghum in the peatlands of West Aceh Regency. This research was carried out from July to November 2023. Several new varieties of sorghum released by the Indonesian Cereals Research Institute (ICERI) were evaluated in the peatland of West Aceh. The research method used a randomized complete block design (RCBD) with two factors and three replications. The first factor was different varieties of sorghum, and the second factor was various doses of fertilizers. The varieties used were Soper 7 Agritan, Bioguma 1, and Suri 3. The doses used Control (no treatment), Dose I (75 kg Urea ha-1 + 50 kg SP-36 ha-1 + 50 kg KCl ha-1), Dose II (150 kg Urea ha-1 + 100 kg SP-36 ha-1 + 100 kg KCl ha-1), and Dose III (225 kg Urea ha-1 + 150 kg SP-36 ha-1 + 150 kg KCl ha-1). The results showed that the Bioguma 1 variety adapted better than the other varieties, where the plant height was 187.97 cm, the number of leaves was 15.08, the panicle diameter was 35.92 mm, and the panicle weight was 79.52 g. Meanwhile, fertilizer dose II is better on the character of the number of leaves and panicle length. The interaction effect between the two factors only showed a significant influence on panicle length. Therefore, the Bioguma 1 sorghum variety can be a recommended variety for planting in the shallow peatlands of West Aceh. Keywords: Acidic soil; alternative food; food diversification

Abstract

The rootstock number and scion types can be used to optimize grafting success. This study aimed to determine the effect of rootstock number, scion type, and its interaction on the success of nutmeg grafting. The research was conducted at the Seed Breeding Site in Layeni Village, Central Maluku Regency, Maluku. The research started in November 2022 and ended in August 2023. The experiment used a two-factor completely randomized design. The first factor was the rootstock number, i.e., single, double, and triple rootstocks. The second factor was the scion type, i.e., Myristica fragrans Houtt, Myristica argentea Warb, and Myristica sp. The 9 treatment combinations were replicated six times, resulting in a total of 54 experimental units. The result of the study concluded that grafting success was influenced by the rootstock number and the scion types, and there was no interaction between rootstock and scion. The highest success was achieved by using a single rootstock with a success rate of 60%. The use of Myristica sp. scions gave the highest grafting percentage of 76.66%. Successful nutmeg grafting was characterized by the presence of a fusion between the rootstock and the scion, based on anatomical observations. Failed nutmeg grafting was characterized by the absence of fusion between rootstock and scion. The rootstock number and scion type affected shoot emergence time, linked stem diameter, shoot length, and leaf number, while the scion type affected the shoot number. Double rootstock tended to have higher parameters than single and triple rootstock for shoot emergence and leaf number, but the number of failed grafting was still challenging.

Abstract

Rice is the main food commodity in Indonesia. The main abiotic factor affecting rice productivity is soil fertility. This study aimed to determine the soil fertility status (SFS) of paddy fields in Polewali District, Polewali Mandar Regency, West Sulawesi. The research was conducted by surveying soil characteristics supported by soil chemical analysis at the Laboratory of Soil Science and Environmental Conservation, Faculty of Agriculture, Universitas Muslim Indonesia. The research was conducted in Polewali District, with the survey area consisting of 4 land map units (LMU). Soil fertility status was determined based on the criteria of each soil fertility parameter, namely: soil pH, organic C-content, cation exchange capacity, available P, Potassium content, and base saturation. The results showed that the SFS in Polewali District was classified as low. Only the base saturation parameters in LMU-2 and LMU-3 were classified as high. In addition, all parameters were only classified as very low to medium at all LMUs. Low C-organic content and very low P and K content are the main limiting factors for SFS. Recommended land management to improve soil fertility is the addition of organic matter that can increase total nitrogen and C-organic in the soil and the application of manure. Keywords: Soil fertility status, paddy fields, rice plants

Abstract

Soybean is an important source of cheap protein. However, an adequate supply of soybeans is still challenging in Indonesia. This research aimed to evaluate the morphological, physiological, and yield responses of soybeans from the application of calcium carbonate (CaCO3), humic acid, and arbuscular mycorrhizal fungi (AMF). The research was conducted from December 2022 to April 2023 at the ultisol soil of Sijunjung Regency, West Sumatra. The experiment used a split-split-plot design with three replications. The first factor was AMF and without AMF application. The second factor was humic acid and without humic acid. The third factor was doses of CaCO3 application: 0, ¼, ½, ¾, and 1 time of exchangeable Al. The results showed that CaCO3 application significantly affected root length, shoot dry weight, N-tissue content, soil pH, and exchangeable Al. The application of AMF affected the percentage of AMF colonization. The yield components did not show any significant differences among treatments. However, the yield was 24.85% higher than that written in the official description. Therefore, the application of CaCO3 or humic acid or AMF could be a potential solution to increase soybean yields in ultisol. It needs further evaluation in the field to support future farming practices. Keywords: Al-exch; calcium carbonate; N-tissue content; productivity; soil pH
