Abstract

Weed resistance, indicated by increasing the level of herbicide for control, might arise due to the continuous use of similar herbicides in the long term without any herbicide rotation. The objective of this research was to evaluate the status of dominant weeds in a guava orchard to determine weed control strategies. The research was carried out from November 2020 to June 2021 at Agribusiness Technology Park IPB, Bogor. Vegetation analysis to define dominance was carried out at 4 blocks using the square method. In each block, five sampling points were randomly selected. Seeds of C. kyllingia were collected and planted as many as 25 seedlings in polybags. Glyphosate herbicide was applied onto C. kyllingia in 3 replications using 9 doses, i.e., 0 (D0), 60.75 (D1), 121.5 (D2), 243 (D3), 486 (D4), 972 (D5), 1944 (D6), 3888 (D7), and 7776 g ha-1 (D8). C. kyllingia mortality percentages were analyzed using linear regression to obtain LD50. The results showed that the dominant weed was C. kyllingia. Block 4 showed the highest significant LD50 value at 759.11 g ha-1 with a resistance index of 2.67 (reduced sensitivity). The presence of dominant C. kyllingia was identified only at block 4, indicating the dominance could correlate with increasing resistance of the particular weed.

Abstract

Excessive leaf production in winged bean may delay the flowering time and reduces the yield, therefore, shoot pruning and additional fertilizer were applied in order to improve yield. The research was carried out at Leuwikopo Experimental Station, IPB University, Bogor from January to July 2022. The study used a randomized complete block design with 2 factors and three replications. The first factor was three types of shoot pruning, namely without shoot pruning, shoot pruning at 15, and 30 cm height. Pruning was conducted at 7 weeks after transplanting (WAT). The second factor was four doses of fertilizers (0, 6.25, 12.5, and 18.75 g of NPK (16-16-16) per plant). The additional fertilizer was given every two weeks from 7 until 15 WAT. The variables observed were the morphophysiological characters, shoot auxin levels, plant nutrient levels, pod yield, pod number, and pod flavonoid content. The results showed that plant’s biomass increased with additional fertilizer, lower relative growth rate and higher auxin content was from 15 cm pruning. The interaction of two factors affected flowering time and flavonoid content. Shoot pruning and 6.25 g NPK delayed flowering by 0.7-1 day. The highest flavonoid content was found in the plant without pruning and additional fertilizer. Plant yields were not significantly affected by treatments. Keywords: auxin; flavonoid content; flowering time; leaf nutrient; young pods

Abstract

Production expansion to suboptimal areas such as tidal land through the application of integrated land management technology is an effort to increase soybean production in Indonesia. The study aimed to evaluate the morphophysiological response of soybean treated with arbuscular mycorrhizal fungi (AMF) inoculation and duration of water saturation in tidal land. The study was conducted in April-October 2021 in the plastic house of the Research Field of the Faculty of Agriculture, Sriwijaya University, Palembang. The experiment used a randomized complete block design with two factors and 3 replications. The first factor was the source of AMF propagations (without inoculations, corn inoculants, soybean inoculants, sugarcane inoculants, and soybean-sugarcane inoculants). The second factor was the water saturation periods (0, 2, and 4 months since planting), so there are 15 treatments. The results showed that the interaction between the inoculant sources and the duration of water saturation had no significant effect on all parameters. The inoculant propagated in the media of sugarcane produced the highest effect as compared to other treatments. The water saturation for 2 or 4 months since planting gave soybean plants a better morphophysiological response than conventional cultivation. Keywords: AMF inoculants; morphophysiology; saturated soil culture; soybean

Abstract

Banana group can be divided into two groups based on their method of its utilization. Banana group that can be eaten immediately after ripening is called "dessert banana", e.g., Raja, while the group that needs particular processing before consumption is called "plantain banana", e.g., Kepok. This study aimed to compare the growth of Raja banana with Kepok plantain through experiments at three stages of the in vitro culture media: the shoot initiation, shoot multiplication, and plantlet acclimatization, also to compare the growth of Raja bananas with Kepok plantains in response to cytokinins BAP and TDZ at shoot multiplication stage. Planting material was in the form of rhizomes that was prepared with the same size. The experiment was performed using a completely randomized design. Results showed that Kepok plantain could adapt faster to the media condition than Raja banana; the phenomenon was evident in the growing speed of Kepok during shoot initiation stage. The proportion of the B genome did not show a direct effect on shoot induction at the multiplication stage or enlargement and organ formation at the acclimatization stage. Shoot induction at the multiplication stage depended more on the composition of the media used. The combination of BAP 3 mg L-1 and TDZ 0.01 mg L-1 in MS media produced the best shoot induction rate, and TDZ 0.01 mg L-1 in MS media had the highest shoot elongation rate. Keywords: banana, BAP, genome, PGR, plantain, TDZ

Abstract

Sorghum is a globally important commodity for food, feed, and fuel, and is known to have a high tolerance to heat, drought, and other abiotic stresses, and have a large genetic variation for grain yield under low-P conditions. Agricultural land in Indonesia is dominated by acid soils with limited P availability, of a total of 144.5 million ha, around 107.3 million ha are acid soils. Information regarding the tolerance of sorghum to P deficiency conditions is still very limited. The review aimed to discuss the adaptation strategy of sorghum to P deficiency. Studies showed that sorghum has a moderate adaptation to Al3+ stress with low P. Under various P levels, the performance of sorghum was also very diverse following the wide genetic diversity. From evaluations of several varieties and inbred lines with high tolerance to P deficiency that has been obtained, sorghum tolerance strategies to low P conditions are: (1) increase root size (length, diameter, and volume), and root proteoid on several genotypes, (2) increase secretion of oxalic acid, particularly in tolerant genotypes, the secretion of which are higher when Al3+ is present, (3) higher P-use efficiency (PUE), eventhough the specific absorption ratio (SAR) was lower than the sensitive ones. The high PUE is thought to contribute to higher grain weight compared to sensitive genotypes under P starvation condition, and (4) higher stay green percentage, which has a high correlation to grain weight/plant. Such strategies should be considered in precission breeding program of sorghum to P deficiency. Keywords: adaptation strategy; oxalic acid; P-use efficiency; sorghum genotypes; sorghum low P; stay green

Abstract

Mengevaluasi pertumbuhan dan produksi varietas di lokasi yang berbeda dapat menjelaskan potensinya untuk beradaptasi secara luas. Varietas yang sama seringkali memiliki performa yang lebih baik di lingkungan tertentu atau bahkan di beberapa lingkungan dan sebaliknya. Penelitian ini mengevaluasi empat varietas bawang putih di dua lokasi dataran tinggi. Varietas yang diuji meliputi Lumbu Putih, Lumbu Hijau, Lumbu Kuning, dan Tawangmangu Baru. Varietas-varietas ini ditanam di Lembang, Jawa Barat (1.250 m dpl) dan Ciwidey, Jawa Barat (1.200 m dpl). Hasil penelitian menunjukkan bahwa interaksi yang signifikan antara varietas dan lokasi berpengaruh nyata terhadap tinggi tanaman, diameter batang semu, bobot segar, bobot kering, dan diameter umbi kering. Lumbu Kuning menghasilkan rata-rata bobot segar tertinggi per sampel dengan perbedaan yang cukup besar di kedua lokasi (Lembang: 52,01 g, Ciwidey: 31,87 g). Varietas ini juga memiliki bobot kering tertinggi 24,65 g ketika ditanam di Lembang. Secara keseluruhan, hasil penelitian ini menunjukkan bahwa Lembang memberikan kondisi yang lebih baik untuk pertumbuhan dan hasil dari ketiga varietas kecuali Lumbu Hijau.

Abstract

Early establishment of shallot growth is important in order to ensure optimum yield. This study aimed to evaluate the effect of seed priming with moringa leaf extract (MLE) and the application of Tithonia compost on the growth of shallots. The research was conducted at the experimental farm belonging to the Faculty of Agriculture, Hasanuddin University, Makassar, from September to December 2022. The study was arranged in a factorial design with three replications. The first factor was priming, consisting of five levels: unprimed, hydropriming, 12.5% MLE, 25% MLE, and 37.5% MLE. The second factor was the level of Tithonia compost, consisting of four levels: 0, 5, 10, and 15 tons ha-1. The results revealed that shallots treated with a combination of priming 37.5% MLE followed by application of 15 tons ha-1 of Tithonia compost in the field had the highest chlorophyll index (25.97). Priming with 37.5% solely resulted in the highest average shallots height (38.23 cm), the number of plant leaves (10.55), leaf weight (15.67 g), and bulb weight (29.92 g). Application of Tithonia compost solely of 15 tons ha-1 produced shallot with the highest average plant height (37.72 cm), the number of plant leaves (9.74), leaf weight (13.68 g), and bulb weight (27.01 g). Seed priming using MLE and application of Tithonia compost are prospective to enhance shallots growth, however, it is important to further evaluate the effect of priming on germination traits and economic evaluation on using Tithonia compost for practical applications in the field.

Abstract

Many peanut planting fields have limited water resources, therefore farmers must use water efficiently. A study aimed to obtain appropriate watering intervals and adaptive peanut cultivars at limited water conditions. The greenhouse study was conducted at Central Bengkulu Regency, Indonesia, from December 2019 to March 2020. Three varieties of peanut (Takar 2, Talam 1, and Kancil) and four watering intervals (1, 3, 6, and 9-day intervals) were arranged using a split-plot design and replicated three times. Results showed that the three varieties evaluated had similar agronomic performance (P≥0.05). The Takar 2 and Kancil had similar growth and yield components to the dry land adaptive variety Talam 1. It indicates that Takar 2 and Kancil cultivars are suitable for cultivation in a water-limited field. Watering every 6 days reduced peanut growth and insignificantly differed from watering every 9 days. Daily watering produced the highest growth and yield of peanut, irrespective of genotypes. Nevertheless, in areas with limited water availability, watering every 3 days was sufficient with yield reduction by about 25.55% of watering daily. Keywords: drought, irrigation, peanut production

Abstract

Leaf morphological characters and nutrient content in leaf tissue can vary depending on plant genotype. The nutrient solution culture can produce leaves with good nutritional content. Therefore, this research aimed to evaluate and validate cassava putative mutants' morphological traits and Zn content using a nutrient solution culture system. This research was carried out from January to May 2022 at the greenhouse of Cikabayan Experimental Garden, IPB University, Bogor. This study used two cassava cultivars and ten mutant genotypes from the cassava research team of IPB University, resulting from mutation breeding by gamma irradiation. The plant characters observed in this study included the number of leaves, length and width of the leaflet, leaf colour, plant height, fresh and dry weight leaf, and analysis of Zn content. The data were analyzed using ANOVA at a significant level of α = 5%, followed by Tukey's further test. The results showed that the G2D1-422 genotype had a higher Zn content than the wild type (Ratim/G2) and the other genotypes. The high Zn genotypes (G2D1-422) and low Zn genotypes (Ratim (G2) had not significantly different in fresh and dry leaf weight. Meanwhile, the plant genotype did not affect other growth characteristics such as plant height, the number of leaves, and the length and width of the leaflets, and overall, the characters were similar between the observed genotypes.

Abstract

Javanese turmeric (Curcuma xanthorrhiza Roxb.) is important for study due to its increasing economic value in many aspects including marker-associated compounds for curcuminoids and xanthorrhizol. This systematic review aimed to summarize and find information about C. xanthorrhiza starting from its pharmacological activity and mechanism as an anticancer, anti-inflammatory, and antioxidant extraction process, and cultivation techniques. The data were obtained from relevant journals in national and international scientific databases PubMed, Scopus, Google Scholar, Web of Science, SINTA, ScienceDirect, and Wiley Online from 2000 to 2023. Results showed that from the perspective of anti-inflammatory pharmacological activities, xanthorrhizol inhibits pain response and inflammatory response. Its antioxidant activity showed a contribution to inhibiting oxidation which also successfully inhibits cancer cell proliferation. The extraction method of xanthorrhizol and curcuminoid compounds with Ultrasonic-Assisted Extraction (UAE) 20-2000 kHz performs better than other methods. C. xanthorrhiza cultivation techniques under shading produce better rhizomes. Based on research on cultivation techniques, extraction methods, and pharmacological activities, C. xanthorrhiza has an important role in the future.
