“…On observation, the highest plant tuber diameter of 3.78 cm was obtained in the combination of treatment B (compost 10 tons / ha and violetta varieties) but did not differ markedly from other treatment combinations. This is in line with the opinions of Mythili et al, (2018) and Petrovic et al, (2019), stating that the use of compost on various varieties does not increase the number of tubers and diameter of tubers but only encourages vegetative growth. In addition, the number of tubers and the diameter of tubers in plants depends on the growth period of plants, especially plant height and number of leaves (Harvendra et al, 2019).…”

This experiment aims to determine the effect of the combination of compost on the growth and yield of plants of three varieties of shallots (Allium ascalonicum L). The experiment was carried out in Karangwangun Village, Babakan District, Cirebon Regency - West Java. The research period will be carried out from January to May 2023. The location is located at an altitude of 93 meters above sea level (asl), the soil type of Latosol and Regosol association, including rain type C (moderately wet). The experimental method used is using an experimental method with a Randomized Group Design (RAK) combination pattern, the treatment consists of two factors that are repeated three times. The first factor is compost which consists of three levels, namely compost 10 tons / ha, compost 15 tons / ha, and compost 20 tons / ha. While the second factor is varieties consisting of three levels, namely pancasona varieties, violetta varieties, and bima varieties. The main observation data were processed using linear model statistical tests, fingerprint analysis, and scott-knot group follow-up test analysis. To determine the correlation between the treatment and the growth and yield components of shallots, the correlation used is with the Product Moment correlation coefficient. The experimental results showed: (1) The combination of compost treatment and onion plant varieties had an effect on the weight of fresh bulbs per plot and the weight of dry tubers per clump, but did not affect plant height, number of leaves, number of saplings per clump, root volume, number of tubers per plant, diameter of tubers per plant, weight of fresh bulbs per plant, and weight of dry tubers per plot, (2) The highest dry tuber weight per plot was produced by a combination of compost treatment of 10 tons / ha and bima varieties of 3.85 kg / plot or equivalent to 10.26 tons / ha and was not significantly different from other treatment combinations, and (3) There was a significant correlation between plant height and the number of leaves aged 35 HST and 45 HST with seed weights per plot with weak and medium categories. However, there was no apparent correlation between plant height and leaf count aged 25 HST with seed weight per plot with very weak category.

“…The effect of this fertilizer was more spectacular than the remaining treatments B-Stimul (based on bacterial and algal cultures) and VermiFit A (compost from Californian earthworms). Beneficial microorganisms are known to be the most effective as plant stimulants in stress conditions, and EkoBooster 2 is composed of organic matter and NPK (nitrogen, phosphorus, potassium) in available forms, which led to the optimal nutritional status of onion plants [23,24]. Hanci and Cebeci [25] noted that drought, occurring especially during the vegetative phase of the onion life cycle, significantly decreased chlorophyll a and b content and total chlorophyll content, but not the chlorophyll a/b ratio, indicating that chlorophyll a was more sensitive to drought.…”

This investigation was conducted to determine the effect of organic fertilizers on the content of chlorophyll a, chlorophyll b, antioxidant activity, crude fibre, and zinc in two onion cultivars, Stuttgarter Riesen and Rote Laaer, during 2016, 2017, and 2018. In this research, the following treatments were used: B-Stimul (contains Azospirillum Tarrand et al., Azotobacter Beij., Bacillus Cohn, Chlorella vulgaris Beij., and Herbaspirillum Baldani et al.), EkoBooster 2 (contains biostimulators and mineral salts of nitrogen, phosphorus, and potassium) and Vermifit A (extract of compost of Californian earthworm). The results showed that the application of biofertilizers to onion resulted in the highest chlorophyll b content in 2017 in Stuttgarter Riesen. EkoBooster 2 positively affected crude fibre content in both cultivars, but only in 2016. Antioxidant activity was not significantly affected by the interaction of experimental factors. The application of the biostimulating fertilizers can have a positive impact on the quality parameters of onion, but the kind of fertilizer must be suited to seasonal conditions and the cultivar.

“…The result is in agreed with (Kaur and Singh (2019), Jayathilake et al (2003) ; Akoun (2004), Mohammad and Hassanpour ( 2012). Organic fertilizers help in onions bulbs production (Petrovic et al, 2019;Vachan and Tripathi ,2017;Shah et al, 2019;El zemrany and Faiyad 2021). The reason for these results may be due to released nutrients and hormone increase soil fertility by increasing soil biota and enhances the plant growth and bulb yield.…”

A field experiment was conducted during the two growing seasons (2019-2020), At Agricultural Experimental Station of the Desert Research Center at Khamisa Village (29.21º N and 25.40º E), Siwa Oasis, Matrouh Governorate, Egypt, to study the effect of biofertilizers (Azotobacter chroococcum, Bacillus megatherium and Pseudomans fluorescence ) and foliar applications with copper, manganese, and iron at two concentrations of 0.2 and 0.4% (Cu, Mn, and Fe). The best results recorded with A. chroococcum combined with 0.4%iron for most parameters. The outcomes were as follows: Both biofertilizer inoculation and micronutrients foliar application gave a synergistic effect and enhanced the uptake of minerals and their metabolism in plants. The application significantly impacted the development, yield, and microbial community in the rhizosphere of inoculated plants. Compared to the control, the interaction treatments between biofertilizer inoculation and micronutrient foliar application had the most positive effects on onion plant growth indices, yield, and microbial activity in the rhizosphere.A.chroococcum increased plant height, leaves number, plant fresh and dry weight specifically with 4.0% iron, bulb diameter with Mn and Fe, yield ,total microbial count with Fe at 2.0 and 4.0% compared with B. megaterium, and Ps.fluorescence. Comparing with Ps.fluorescence and A.chroococcum, B.megaterium recorded the highest, bulb weight, bulb diameter with copper (Cu), total soluble solids (TSS), total microbial count with Cu and Mn, Bacillus count and phosphatase activity.
