“…These three karyotypes revealed that shallot plants have symmetrical karyotypes. The symmetrical karyotype is a karyotype with a uniform chromosome type and is considered more primitive than an asymmetric karyotype (Ermayanti et al, 2019;Nemtinov et al, 2021). The ideogram results revealed that the chromosome lengths between control and Bio-Catharantin treatments were different.…”

The seasonal production of Allium cepa var. ascalonicum causes a rise in its demand during the off-season. Consumers mostly prefer onion cultivars like the 'Super Philip', because of their high productivity, large and round bulbs, shiny appearance, and less spicy taste. In plant breeding, polyploidy induction through mutagens is a technique often used to produce shallot cultivars of better quality. Bio-Catharantin from the leaf extract of Catharanthus roseus L. is used as a polyploid induction agent instead of colchicine. The latest study aimed to determine the effect of Bio-Catharantin concentration (0.2% and 0.4%) on phenotypic traits (plant height, bulb mass, and the number of bulbs), and the chromosome number to determine the minimum concentration that could cause polyploidization in shallots. The research was conducted from December 2020 to February 2021 in a greenhouse in Madurejo, Prambanan, and the Laboratory of Genetics and Breeding, Faculty of Biology, Gadjah Mada University, Indonesia. Bio-Catharantin concentration did not affect plant height which was comparable with the control. Both treatments caused an increase in bulb mass up to 37.7 and 41.76 g at the concentrations of 0.2% and 0.4%, respectively, compared with the control (31.47 g). The number of bulbs increased up to 10.6 and 9.8 g for 0.2% and 0.4% concentrations, respectively, compared with 8.8 in the control. The ploidy level of cells was increased from 2n (16) to 3n (24) at 2% and 4n (32) at 4% Bio-Catharantin.

“…Shallots are one of the most indemand commodities, as almost every typical Indonesian dish, and are used either as a condiment or as a flavoring. Another use of shallots is in traditional medicines (Nemtinov et al, 2021). It can be used to relieve fever by rubbing the oil all over the body.…”

“…Nitrogen, phosphorus, and potassium concentrations ranged from 0.95%, 0.38%, and 1.93% (control treatment) to 2.94%, 0.93%, and 4.71% (1.0 g/L Nano NPK + 0.5 g/L algae extract), respectively, and the micronutrients Fe, Mn, Zn, and Cu concentrations ranged from 42.77%, 33.6%, 81.43%, and 16.40% (control treatment) to 219.10%, 76.4%, 104.23%, and 32.27% (1.0 g/L Nano NPK + 0.5 g/L algae extract), correspondingly. The smaller size, the higher the specific surface area, and the reactivity of biostimulants (nanofertilizers) may affect nutrient solubility, diffusion, and availability to plants (Singh et al, 2013;Nemtinov et al, 2021;Billa et al, 2022;Maharijaya et al, 2023). The use of nanoscale fertilizers may additionally assist in minimizing nutrient loss through leaching or run-off, restricting its speedy degradation and volatility, improving the nutrient quality and fertility of the soil, and promoting crop productivity in the long run (Rautela et al, 2021).…”

Biostimulants (nano fertilizers, algal extract) are synthetic or natural compounds for application to seeds, plants, and soil to increase crops, particularly onion yields. These substances cause changes in vital structural processes to influence plant growth through improved tolerance to abiotic stresses and enhance seed and grain yield and quality. The presented study aims to determine if biostimulants beneficially increase onions’ vegetative growth, harvest, and quality of onions (Allium cepa L.). A randomized complete block design with three replications helped compare various rates of Nano NPK fertilization (0.1, 0.2, 0.4, 0.6, 0.8, and 1.0 g/L Nano NPK + 0.5 g/L algae extract, 1.0 g/L mineral NPK + 0.5 g/L algae extract, 1.0 g/L mineral NPK, 1.0 g/L Nano NPK, and 0.5 g/L algae extract) with the control treatment (spraying distilled water only). The results showed as the Nano NPK + 0.5 g/L algae extract levels decreased, all studied parameters gradually declined. Foliar application of Nano NPK 1.0 g/L combined with 0.5 g/L algae recorded the highest significant effects, followed by 1.0 g/L mineral NPK + 0.5 g/L algae and 0.8 g/L Nano NPK + 0.5 g/L algae compared with the control. The highest values of bulb diameter (10.1 cm/plant), plant height (108.7 cm/plant), plant fresh weight (254.7 g/plant), and fresh yield (25.67 t/ha) emerged with foliar application of Nano NPK 1.0 g/L combined with 0.5 g/L algae, and the lowest values, obtained from the control treatment, were 4.2 cm/plant, 62.3 cm/plant, 100.23 g/plant, and 10.09 t/ha, respectively. The results suggested that using the algae extract combined with nano fertilizer treatment as a biostimulant will maximize onion growth parameters, yield production, and nutrient contents

Onions, a crucial bulb crop cultivated globally, including in Ethiopia, face significant production challenges. These constraints encompass poor soil fertility, inappropriate fertilizer usage, limited availability of improved varieties, disease and insect pests, and the high costs associated with commercial fertilizers. Among these limitations, improper fertilizer application amounts and types play a pivotal role in restricting onion production. To address this, a field experiment was conducted during the 2020-2021 cropping season in the Shewa Robit district of the North Shewa zone. The study assessed the impact of NPS and Zn fertilizer rates on onion growth and yield. The treatments included four NPS fertilizer rates (0, 121, 242, and 363 kg/ha) and four levels of ZnSO4 (0, 0.25, 0.5, and 0.75% w/v). The experiment was laid out as a randomized complete block design in a factorial arrangement and replicated three times. The results demonstrated that the interaction effect of NPS and Zn fertilizers significantly influenced various onion parameters, including days to maturity, plant height, leaf length, marketable bulb yield, unmarketable bulb yield, and total bulb yield. The application of NPS at a rate of 242 kg/ha and 0.75% ZnSO4 led to the highest plant height (65.20 cm), leaf length (51.93 cm), marketable bulb yield (34.87 t/ha), and total bulb yield (35.04 t/ha). In addition, this treatment combination yielded the highest net benefit (908,628.89 ETB/ha) with an acceptable MRR (313.64%) compared to other treatments. Hence, it can be recommended for economical production of onion in the study area and areas with similar agroecologies.
