“…Since Mann () proposed the Bulbing Ratio ( Bulbing Index – BI) as a simple method to determine when bulbing begins, numerous authors have used this method due to the importance of this phase in the growth of garlic (Rahim & Fordham, ; Brewster & Rabinowitch, ; Argüello et al , ; Ledesma et al , ; Núñez et al , ). This index results from the ratio of the diameter of the neck (pseudo‐stem) to the equatorial diameter of the bulb in any given moment; values are never greater than 1 and decrease to the extent that the bulb develops.…”

“…This index results from the ratio of the diameter of the neck (pseudo‐stem) to the equatorial diameter of the bulb in any given moment; values are never greater than 1 and decrease to the extent that the bulb develops. Normally, the bulbing phase is assumed to begin when values near 0.50 (Argüello et al , ), and values decrease to 0.25–0.20 during harvest (Brewster & Rabinowitch, ). Ledesma et al () differentiated BI values to an even greater extent and outlined two distinct bulbing phases for soft‐neck cultivars.…”

The advantages of using Biologische Bundesanstalt, Bundessortenamt and Chemische Industrie (BBCH) phenological scales are well-known in the field of agronomy. Currently, specific scales exist for the majority of crops. Although garlic has international importance due to its worldwide cultivation, a specific phenological scale has not been developed; in general, garlic is integrated into the BBCH description for onion. While garlic and onion belong to the same genus, this generalisation should be avoided due to their many differences. The means of propagation of garlic is vegetative, from cloves of the previous cycle, and the concurrence of the bulbing phase and the emergence of the inflorescence (bolting types) cause garlic to perpetually remain in a 'second year stage' of its biological cycle. In contrast, onions and other bulbous Liliaceae that produce seeds undergo biannual development. In addition to this complexity, its physiological complex is strongly influenced by environmental factors, such as temperature and photoperiod; distinct conditions are required for overlapping or simultaneously occurring phases (bulbing/flowering). Nevertheless, ambiguity and lack of consensus exist concerning the start of different phenological phases due to the complex morphology of the bulb (composed of a bulb of bulbs/cloves). During bulbing, for example, two distinct, consecutive processes are involved: the differentiation of lateral buds and inflorescence (bolting types) and the thickening of the storage leaf of each bud (cloves). In the present study, an extended BBCH scale was developed for garlic (Allium sativum). Seven principal growth stages divided into secondary growth stages are described in detail and are represented by a two-or three-digit code. Descriptions begin with garlic cloves in a stage of dormancy, destined for planting and end with complete bulb maturity. The most complex growth stages of garlic were described from a morphological and physiological perspective, that is complete bolting types (hard-neck cultivars). Illustrations of different stages are included to clarify the application of the code system. The proposed BBCH garlic scale aims to fill gaps in the knowledge of this important crop and will serve as a useful tool for researchers, technicians and farmers. Thus, experimental findings may be standardised and complementary, which may lead to improvements in management practices and their comparisons. gastronomy of a multitude of cultures (

“…In the current agronomical context, the use of solid agricultural waste (vermicompost) in garlic production constitutes a valid alternative, though the physiological and/or agronomical implications of such use are unknown. Argüello et al, (1997) determined the critical period for fertilizing garlic may be between the initiation of shoot growth and the beginning of bulb filling. In particular, previous work on traditional fertilization, such as urea on garlic, show the fertilization advances the onset of bulbification by 5 to 6 d, which favorably lengthens the period of bulb filling, increases the bulb's dry weight by 10%, and increases yield and quality (Ledesma et al, 2000).…”

The objectives of this work were to a) determine vermicompost effect on bulbification dynamics in terms of garlic (Allium sativum L.) bulb dry weight and sucrose metabolism and b) evaluate the impact of vermicompost on garlic bulb yield and quality. The treatments were soil (control) and 1 soil: 1 vermicompost (by volume). The use of vermicompost as a substrate caused early bulbing (18 to 20 days) and lengthened bulb filling period. Bulb filling period corresponded to an increase in the total soluble carbohydrates and a later modification in nonstructural carbohydrate distribution patterns regarding fructan (scorodose) metabolism. The vermicompost treatment increased scorodose accumulation, which was directly related to the harvest index, resulting in greater yield and bulb quality. Bulb quality was not modified in terms of bulb pungency and soluble solids content by the use of vermicompost.

“…The results found from the findings of [18,24,23,25], were similar with the present study. Bulb development in garlic depend on an increase in total soluble carbohydrate in photosynthetic activity of the leaves which depend on light and nutrition [26]. [27] reported that increasing nitrogen level upto 100 kg resulted in the maximum single bulb weight (42.60 g) of garlic.…”

A field experiment was conducted at the horticulture farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during October 2019 to July 2020 to study the effect of different levels of vermicompost and macro nutrients on the growth and yield of garlic. Garlic variety ‘BARI Rashun-3’ was used as planting material in this study. The experiment consists of single factor. Twelve treatment combinations were tested in this experiment: T0 = Control, T1 = 2 t ha-1 vermicompost, T2 = 4 t ha-1 vermicompost, T3 = 6 t ha-1 vermicompost, T4 = 50% NPKS (RDF), T5 = 100% NPKS (RDF), T6 = 2 t ha-1 vermicompost + 50% NPKS (RDF), T7 = 4 t ha-1 vermicompost + 50% NPKS (RDF), T8 = 6 t ha-1 vermicompost + 50% NPKS (RDF), T9 = 2 t ha-1 vermicompost + 100% NPKS (RDF), T10 = 4 t ha-1 vermicompost + 100% NPKS (RDF) and T11 = 6 t ha-1 vermicompost + 100% NPKS (RDF). The experiment was laid out in Randomized Complete Block Design (RCBD) with 12 treatment combinations having three replications. Data on different growth and yield parameter of garlic were recorded and significant variation was recorded for different treatments. Plant height and number of leaves plant-1 value of garlic was recorded to be the maximum from treatment T10 (4.00 t ha-1 vermicompost + 100% NPKS (RDF)) at different days after sowing (DAS). But, the highest bulb diameter (3.32 cm), the longest clove (3.44 cm), the highest bulb length (2.43 cm), the maximum number of cloves bulb-1 (21.25), the maximum fresh weight of bulb (35.11 g), the maximum dry weight of bulb (4.95 g), the highest fresh clove weight (6.93 g), the maximum dry clove weight (1.89 g), the maximum fresh weight of leaves plant-1 (25.31 g), the maximum dry weight of leaves (3.31 g), the highest bulb yield plot-1 (1.45 kg) and the maximum yield of garlic (14.53 t ha-1) was recorded from T11 (6.00 t ha-1 vermicompost + 100% NPKS (RDF) treatment.
