- DRIS II: Interpretation of DRIS indices in oil palm cultivation
Authors: Gustavo Enrique Herrera-Peña, Saúl Dussán-Sarria, Jesús Hernán Camacho-Tamayo
Pages: e16095 - e16095
Abstract: The nutritional diagnosis based on leaf tissue analysis is an efficient tool for detecting nutritional imbalances and assisting the fertilizer recommendation process. Therefore, the objective was to use the indices obtained through the Integrated Diagnosis and Recommendation System (DRIS) in oil palm cultivation to interpret them based on the criteria of excess limitation (LE), deficiency limitation (LF), and non-limiting (NL). It was found that sulfur, potassium, and magnesium are not presenting any limitations for production, while zinc, iron, and copper showed deficiency limitations, and nitrogen an excess limitation. The likelihood of a reaction to an augmented nutrient supply via fertilizers was assessed. The results revealed a strong likelihood of a negative response for nitrogen, while elements like phosphorus, potassium, calcium, magnesium, sulfur, zinc, and boron exhibited no significant response. As a final implemented methodology, critical levels and sufficiency ranges were calculated for each element, based on the correlation between the nutrient quantity in leaf tissue and the DRIS index obtained for each element in everyone. Differences were found compared to what has been reported by other authors.

peruviana L. genotypes
Authors: Francy Liliana García-Arias, Erika Sánchez-Betancourt, Franklin Giovanny Mayorga-Cubillos, David Rodríguez-Puertas, Víctor Manuel Núñez-Zarantes
Pages: e16231 - e16231
Abstract: Cape gooseberry (Physalis peruviana L.) productivity in Colombia can be increased by developing high-yielding and adaptable varieties identified in multi-environment trials. In this study, the genotype-by-environment interaction (G×E) for fruit yield and fruit weight of 13 cape gooseberry genotypes at seven locations was evaluated using a randomized complete block design. G×E interaction was significant for yield and fruit weight, suggesting a differential response of genotypes across environments. Through the AMMI analysis, similar and contrasting environments were identified, as well as the genotypes that contributed the most to the G×E interaction. Genotypes I, B, D, and H were the high yielding, ranging from 25.2 to 27.3 t ha-1, so they could be recommended for commercial cultivation. Genotypes B and D was stable in yield and widely adapted; while the genotypes I and H showed a specific adaptation for yield and exhibited heavier fruits. Genotype R1 exhibited the greater fruit weight in most locations except Ipiales but showed low fruit yield. The suitable locations for the cultivation of cape gooseberry were Pasto, Puerres, and Ipiales since they presented the highest yields and fruit weight.

- Insecticidal and phytotoxic activity of essential oil from Colombian
Eryngium foetidum L.
Authors: Víctor Rodríguez-Orozco, Beatriz Eugenia Jaramillo-Colorado, A. Sonia Olmeda
Abstract: Eryngium foetidum L. is a biennial herb belonging to the family Apiaceae, which is used extensively as a medicinal plant in most tropical regions. In this research work, the activity of the essential oil (EO) from E. foetidum against the Hyalomma lusitanicum Koch, and its phytotoxicity in germination of seeds of Lolium perenne and Lactuca sativa was studied. E. foetidum EO was isolated by the hydrodistillation technique. Gas chromatography coupled to mass spectrometry (GC-MS) was used to identify the volatile metabolites. Fifteen compounds were found in the E. foetidum EO. The major compounds were E-2-dodecenal (53.0%), trimetilbenzaldehyde (duraldehyde) (14.8%), cyclododecane (4.4%), trans-tetradec-enal (3.9%), decanal (3.6%), and trans-2-dodecen-1-ol (3.0%) and D-limonene (1.5%), respectively. The E. foetidum EO, and two of its individual main compounds (2-dodecenal, and duraldehyde) had low phytotoxic activity when were compared with the percentage of inhibition of germination of the blank (carvone), in seeds of L. perenne and L. sativa. The acaricidal activity against Hyalomma lusitanicum was determined using a probit analysis (P>0.05). The essential oil of E. foetidum showed 100% mortality at a concentration of 10 µg µL-1, and LC50 = 4.2 µg µL-1. The results obtained from the essential oil of E. foetidum show a great potential to develop natural biocides for the control of H. lusitanicum due to its chemical composition rich in aldehydes and benzene derivatives, and without adverse phytotoxic effects.

- Selection and evaluation of gene-edited knockout mutants of AtAAP2 and
AtCRF4 homologs of rice for agronomic nitrogen use efficiency (ANUE)
Authors: Kentaro Wakatabi, Michael Gomez Selvaraj, Diego Alexander Guzmán-Prada, Juan Bosco Cuásquer, Karina López-López, Masaki Endo, Manabu Ishitani
Pages: e16120 - e16120
Abstract: Nitrogen (N) is essential for amino acid synthesis in rice production, but its excessive use poses an environmental concern. This research aimed to improve rice agronomic nitrogen use efficiency (ANUE) by knockout (KO) of rice homologs of the two selected genes from Arabidopsis thaliana: AtAAP2, an amino acid permease involved in N transportation in shoots, and AtCRF4, a transcription factor participating in N uptake in roots. The homologs of these genes in rice were identified based on amino acid sequence similarity and knocked out using CRISPR/Cas9 mediated gene editing (GE). The AAP2-KO and CRF4-KO lines were subjected to agronomic evaluations with three N doses: 100% (180 kg ha-1), 50% (90 kg ha-1), and 0% (0 kg ha-1) and showed a 130-175% increase in dry biomass weight and a 183-313% increase in panicle number compared to wild type (WT) in the first experiment. These lines also had slower leaf senescence, the so-called “stay-green” trait, indicating the KO effect of target genes in N metabolism. However, neither AAP2-KO nor CRF4-KO showed better yield or ANUE than WT. This study demonstrated the usefulness of GE technology in gene evaluation and highlighted the effects of AtAAP2 and AtCRF4 genes in the plant N cycle.

- Propagation of Cannabis sativa (L.) plants through cuttings and use of
auxin phytoregulators
Authors: Beatriz Porras-García, Elberth Hernado Pinzón-Sandoval, Pedro José Almanza-Merchán
Pages: e16428 - e16428
Abstract: Cannabis sativa (L.) is an annual herbaceous species which has been extensively cultivated and used as a medicinal plant and for recreational purposes. Its medicinal value is primarily attributed to a group of secondary metabolites called phytocannabinoids, which are mainly concentrated in the essential oils of unfertilized female flowers. Asexual reproduction allows for the offspring of plant material while maintaining the genetic characteristics of the mother plant. The aim of the research was to improve the vegetative propagation process of Cannabis sativa (L.) cv. Eco-2, which has characteristics of medicinal phytocannabinoid producers, using auxin plant growth regulators (NAA and IBA) at different doses. The study was conducted under greenhouse conditions in the municipality of Pesca (Colombia). Doses of 400, 800 and 1,000 mg L-1 and a control without application were evaluated for plant height, stem diameter, number of branches, root volume and length, and rooting percentage. The best treatment was obtained with the application of NAA at a dose of 800 mg L-1, which resulted in a rooting percentage of 86.6%, a root length and volume of 9.0 cm and 5.0 cm3, and an increase in the length of the cutting by 3.8 cm, with significant differences compared to the treatment without application, after 4 weeks of planting. The use of auxin plant growth regulators becomes an alternative with high potential for the propagation of medicinal cannabinoid-producing plants.

Abstract: The potato crop (Solanum tuberosum L.) is considered as one of the main agricultural products in the cold climate regions of Colombia. However, these areas often feature acidic soils with Andean properties, leading to limited availability of essential elements like phosphorus, calcium, magnesium, and beneficial elements such as silicon. Consequently, we assessed the impact of applying increasing doses of three silicate fertilizer amendments on the growth and production parameters of the 'Diacol Capiro' potato within an acidic desaturated soil located in Soraca (Colombia). Two evaluation cycles were executed, each adopting a completely randomized design with 10 treatments. These treatments comprised three doses (300, 600, and 900 kg ha-1) of three amendments (thermal phosphate, double calcium, and magnesium silicate, and Triple 30® amendment (Rio Claro, Medellin)), in addition to a control treatment. Growth variables, encompassing fresh and dry biomass accumulation in aboveground and root components, leaf thickness, leaf area, and total yield, were evaluated. Statistical differences were evident among treatments (P<0.05) for all growth variables and total yield. A discernible response surfaced concerning silicate fertilizer dosage and type. Particularly, the double calcium and magnesium silicate, administered at a dosage of 900 kg ha-1, elicited the most favorable growth and production (61.8±4.1 t ha-1) response. This underscores the potential of silicate fertilizers as a noteworthy alternative for enhancing growth and production in potato plants under the specific conditions of this study.

- Assessment of Burkholderia glumae control in rice (Oryza sativa) FEDEARROZ
67, using silver nanoparticles (AgNPs) under greenhouse conditions
Authors: Carlos Ernesto Morales-Becerra, Luz Yineth Ortiz-Rojas, Giovanni Chaves-Bedoya
Pages: e16358 - e16358
Abstract: Bacterial panicle blight, caused by Burkholderia glumae, represents a significant threat to global rice production, jeopardizing future food security. The severity of this seed-borne disease has been amplified by shifting environmental conditions, yet effective control strategies and fully-resistant rice varieties remain elusive. This research was conducted with the FEDEARROZ 67 rice variety sourced from Agua Clara, Cucuta municipality, and tests were undertaken under controlled greenhouse conditions at Universidad Francisco de Paula Santander. Our objective was to assess the potential of electrochemically synthesized silver nanoparticles (AgNPs) for controlling B. glumae. We employed a completely randomized design with five treatments: preventive, curative, positive control, negative control, and absolute control. Variables analyzed included the number of chlorotic leaves, plant height, and weight. Statistical analyses encompassed variance analysis and Tukey's mean comparison tests using XLSTATS version 2018. Our findings revealed that the preventive treatment with AgNPs at a 5 ppm concentration exhibited significant phytoprotective effects against B. glumae. Plants under this treatment showcased fewer chlorotic symptoms and greater heights and weights compared to controls. These findings underline the potential of nanotechnology as a groundbreaking tool for combating bacterial diseases in essential crops such as rice, thereby contributing to a sustainable future for global agriculture.

Abstract: Quinoa (Chenopodium quinoa) exhibits great potential for adaptation to various agroecological conditions, making it a diversification option for different production systems. In this regard, the objective of this study was to evaluate and compare the agronomic characteristics of different progenies intercropped with coffee (Coffea arabica) cultivation under Popayan (Colombia) conditions, in order to determine their adaptation potential in coffee regions of Colombia. The research was conducted at the Experimental Farm "La Prosperidad", located in the municipality of Popayan, Colombia, at an altitude of 1,800 m. Ten genotypes were evaluated: five selected from BRS Syetetuba (Brazil), three from Colombia (San José, Aurora, and Blanca Dulce de Jericó), and two from Ecuador (Piartal and Tunkahuan). The planting was done between the coffee rows in the zoca stage, in an experimental area of 406 m2, following a completely randomized block design with four replications. Characteristics such as plant height, panicle size, central panicle perimeter, weight of 1,000 grains, grain yield, dry mass yield, harvest index, and phenological stages were evaluated. All quinoa materials showed an early cycle with a maximum value of 118 days, with ‘San José’, ‘Aurora’, ‘BCX1’, and ‘BCX4’ standing out with averages below 110 days. Grain yields ranged from 1,120 to 2,900 kg ha-1, with the genotype BCX6 standing out with 2,900 kg ha-1 and ‘Piartal’ with 2,883 kg ha-1. The weight of 1,000 grains averaged 2.62 g, and the harvest index was 27.96%. Meanwhile, the contribution of dry matter to the intercropped system was 7,799.50 kg ha-1. The genotypes showed adaptation potential in the intercropping system with coffee. A high variability of quinoa genotypes was observed, which is an interesting characteristic for specific selection processes in diversified production arrangements.
