The research was carried out at the research station of the College of Agriculture - University of Kufa during the growing season of 2022-2023 to demonstrate the effect of biofertilizers and phosphate fertilization on the growth of Iris flowers. Bacillus subtilis, Pseudomonas fluorescens, Azotobacter chroococcum by injecting the bacteria into the culture medium before planting the bulbs, and the second was foliar spray using superphosphate Nano-fertilizer at levels 0, 1, or 2 mg/L. The bulbs were cultivated on 10/24/2022 in a factorial experiment with three replications as Randomized Complete Block Design (R.C.B.D). Results showed that when phosphate Nano-fertilizer concentrations rose, so did indicator levels. It was also discovered that regardless of the type of bacteria used for fertilization, the results were the same: an increase in the growth markers of interest. In contrast to most Single and nested transactions, the results showed that the bacteria A. chroococcum at the treatment of P2 fertilization (2 mg/L) recorded the highest values for plant height, number of leaves, vegetative dry weight, number of bulbs, bulb diameter, and root dry weight. In comparison to other varieties of bacteria at the same stage of fertilization, however, it showed no significant differences.

Production Potential and Shelf-Life of Shallot as Affected by Inorganic Fertilizers Complemented with Organic Fertilizer and Rice Husk Charcoal in Dryland

Shallot (Allium cepa L.) is one of the important horticultural commodities with high economic value in Indonesia. The extent of planting areas in marginal land requires technological innovation for the development of shallot such as improvement and location-specific technological innovation. This research aims to observe the effect of various doses of inorganic fertilizers complemented with organic fertilizer and rice husk charcoal on the production and shelf-life of shallot. The study was conducted from March to June 2019 in East Lombok using a completely randomized block design with 1 factor and 5 levels of treatment: A1 (farmer’s practices: 0 kg/ha organic fertilizer; 0 kg/ha rice husk charcoal; 300 kg/ha urea; 250 kg/ha NPK+Zn; and 100 kg/ha SP-36), A2 (10,000 kg/ha organic fertilizer; 10,000 kg/ha rice husk charcoal; 75 kg/ha urea; 62.5 kg/ha NPK+Zn; and 25 kg/ha SP-36), A3 (10,000 kg/ha organic fertilizer; 10,000 rice kg/ha husk charcoal; 150 kg/ha urea; 125 kg/ha NPK+Zn; and 50 kg/ha SP-36), A4 (10,000 kg/ha organic fertilizer; 10,000 kg/ha rice husk charcoal; 225 kg/ha urea; 187.5 kg/ha NPK+Zn; and 75 kg/ha SP-36) and A5 (10,000 kg/ha organic fertilizer; 10,000 kg/ha rice husk charcoal; 300 kg/ha urea; 250 kg/ha NPK+Zn; and 100 kg/ha SP-36). Results showed that plant height and leaf number were not significantly different in various treatments. The bulb number showed that at the age of 20 and 70 days after sowing, the highest value was shown in the A3, and the lowest value was shown in A1 and A2 treatments. Meanwhile, treatment of A5 can reduce weight loss of the prospective seeds.

Coping with Water Stress: Ameliorative Effects of Combined Treatments of Salicylic Acid and Glycine Betaine on the Biometric Traits and Water-Use Efficiency of Onion (Allium cepa) Cultivated under Deficit Drip Irrigation.

Freshwater scarcity is a major global challenge threatening food security. Agriculture requires huge quantities of water to feed the ever-increasing human population. Sustainable irrigation techniques such as deficit drip irrigation (DDI) are warranted to increase efficiency and maximize yield. However, DDI has been reported to cause water stress in plants. The study aimed to investigate the influence of the exogenous application of salicylic acid alone (SA) or in combination with glycine betaine (GB) on the growth, yield quality, and water-use efficiency of onions under different DDI treatments (100%, 70%, and 40% field capacity (FC)). Spray treatments (sub-treatments) were as follows: T1: (distilled water), T2: (1.09 mM SA), T3: (1.09 mM SA + 25 mM GB), T4: (1.09 mM SA + 50 mM GB), and T5: (1.09 mM SA + 100 mM GB). Our results indicated that T2 slightly ameliorated the effects of water stress by improved plant heights, leaf number, pseudostem diameter, bulb quality, and nutrient content of onion bulbs, especially under the 70% FC treatment. However, T3 recorded the poorest results on leaf number, pseudostem diameter, and bulb quality under the 70% and 40% FC treatments. Generally, our results indicated that onions could tolerate moderate water stress (70% FC) without severely affecting the growth and yield of onion. In conditions where freshwater is a limiting factor, a DDI treatment of 40% FC is recommended.

Plant growth promoting rhizobacteria application increased growth and yield of shallot supplied with NPK fertilizer

ABSTRACT Shallot (Allium cepa L. var. Aggregtum group) production fluctuates duo to use of synthetic fertilizer. The effect of how Plant Growth Promoting Rhizobacteria (PGPR) and NPK affect growth and yield of shallot in a pot experiment were examined. The first factor consisted of 0, 10, 20, and 30 mL·L−1 of PGPR, the second treatment consisted of 0.8, 1.2, or 1.6 g of NPK per pot. There was no interaction between PGPR and synthetic fertilizer on growth and yield. The PGPR increased growth and yield of shallot when PGPR doses rose. The 30 mL·L−1 basal dose of PGPR increased plant height (39.96 cm), number of leaves per plant (42.33), fresh bulb weight per plant (53.46 g), and number of bulbs per plant (9.78). The 1.8 g NPK increased number of leaves (42.17) and number of fresh bulbs per plant (9.25), which gradually decreased when doses were reduced. Increasing applied synthetic fertilizer produced improved growth and yield of shallot. Under sustainable crop management, PGPR application could further enhance growth and yield of shallot.

APLIKASI PUPUK KALIUM CAIR PLUS UNTUK MENINGKATKAN KUALITAS BAWANG MERAH DI ADIPALA, CILACAP

One of the important factors influencing crop production is nutrition, which depends on soil fertility and fertilizer application. Nutrition will affect the weight loss of shallots. Shallots can loss weight loss of 25-40% during drying and 17% during storage. One of the nutrients that affect weight loss is potassium. Potassium is an element that plays an important role for plants in the process of photosynthesis, energy storage, protein synthesis, translocation of photosynthetic products. Potassium also plays a role in protecting the osmotic potential of plants in regulating the closing and opening of stomata so that plants can maintain water conditions which will have a good impact on photosynthesis and the flow of assimilate from leaves to plant parts. This study aimed to determine the effect of liquid potassium fertilizer plus application on the quality of shallots. The research was conducted in Adipala, Cilacap which has a height of 10 m above sea level and a temperature ranging from 23-30o C. The land area used is 50 m2. The study was conducted from June 2021 to September 2021. This study used a non-factorial randomized block design with four treatments, namely (1) 0 ml/plot, (2) 1 ml/plot, (3) 1.5 ml/plot, and (4) 2 ml/plot with ten replications. Data were analised using Anova and than follow DMRT at error 0,5%. The variables observed were: plant height, number of leaves, number of bulb, total fresh weight, total dry weight of askip, bulb diameter, bulb hardness and crop yield/plot. The results showed that the application of liquid potassium fertilizer plus had no significant effect on plant height, number of leaves, number of bulb, total fresh weight, total dry weight of askip, blub diameter, and crop yield/plot, but significantly affected the hardness of shallot bulbs.

Growth and yield of shallot (<em>Allium ascalonicum</em> L.) as influenced by soil application of liquid urea and cow urine

This experiment was carried to evaluate the effect of liquid urea and cow urine with cow dung on the economic yield of shallot (Allium ascalonicum L.) in the Eastern Province of Sri Lanka. The experiment was arranged in a Completely Randomized Design (CRD) with eight replicates and six treatments namely, T1: 20 g cow dung, T2: 20 g cow dung + 3% urea, T3: 20 g cow dung + 3% cow urine, T4: 30 g cow dung, T5: 30 g cow dung + 3% urea, and T6: 30 g cow dung + 3% cow urine. The soil applications of liquid urea and cow urine were done as top dressing at two weeks interval from 3rd week after planting (WAP). Data were collected at 3rd, 5th, 7th, and 9th WAP and at harvesting stage. The results revealed that there were significant (P<0.001) variations in plant height, number of bulbs, bulb diameter, fresh weight of single bulb, number of roots, root length, dry weight of leaves, dry weight of bulbs per plant and bulb yield per unit land among the treatments. Relatively higher yield (37.5 t/ha) was obtained from the plants treated with 30 g cow dung and 3% urea (T5) than other treatments whereas 20 g cow dung alone (T1) produced the lowest yield (8.4 t/ha). T6 (30 g cow dung and 3% cow urine) gave 32.6 t/ha bulb yield. It was also noted that there was no remarkable (P>0.05) difference in the bulb yields between T2 and T3. However, significant variation was observed between T5 and T6. The combined effect of cow dung and liquid urea fertilizer increased the onion yield. From this study, it could be stated that 30 g cow dung with 3% urea or 3% cow urine could give high bulb yield in the shallot cultivation at rural areas in Sri Lanka where farmers could easily collect the locally available materials for crop production in ecofriendly manner.

Application of silicon foliar spray to increase growth and yield of shallot (Allium ascalonicum L.) under sprinkler and furrow irrigation system

Silicon foliar application can help mitigate the negative effects of drought stress and is an important component of climate-smart agriculture. This study aimed to assess the effect of various concentrations of silicon foliar spray (SFS) on shallot growth and yield under two irrigation systems. On-farm experiment was arranged in the randomized block with split-plot design in dryland of East Lombok District of Nusa Tenggara Barat (NTB) Province during dry season of 2018. The main plot was furrow and sprinkler irrigation system, and the sub-plot was four concentrations of SFS (0, 15, 30, and 45 ml) with five replications. In general, plant height, leaf number, bulb number, and fresh biomass of shallot were increased following the increase of SFS concentration, with the optimal dosage being 15 ml/lt for the experiment site. Shallot fresh yield was significantly higher under sprinkler irrigation (3.72 kg/m2) compared to furrow irrigation (2.70 kg/m2). The significant interaction effects were found on plant height (20 and 40 days after planting) and weight loss (after sun-dried and after 90 days of storage to produce bulb seeds). All in all, the sun-dried shallot yield was significantly higher from 14.76% (30 ml) to 28.40% (15 ml) compared to the control.

Shallot growth and production responses to application of microorganisms based-biostimulant and NPK fertilizer combinations on acid soil

Shallot plants require attention because the demand for this high-value commodity is increasing, especially as Indonesia expands its cultivation over a large area of land. This study aimed to assess the potential of microorganism-based biostimulant formula doses and NPK combinations in promoting shallot growth and production in acidic soil. The experiment used an RCD with four treatments: P=control; P1=standard NPK (600 kg· ha1 urea, 250 kg·ha1 SP-36, and 175 kg·ha1 KCl); P2=3 ml L1 biostimulant + 3/4 standard NPK; and P3=5 ml L1 biostimulant + 3/4 standard NPK with four replications. The observed parameters were plant height, number of leaves and bulbs, as well as bulb fresh and bulb dry weights. The results showed that all treatments gave significantly different effects on all observed parameters. Treatment of P1, P2 and P3 showed a higher bulb’s number and dry weight than control. The P3 is an optimal treatment with a bulb number of 10.0 ± 2.2 per clump. This biostimulant formula is an eco-friendly, renewable, and promising technology for improving the growth and production of shallots in acidic soil.

Mushroom Media Waste and Goat Manure Application on Growth and Yield of Shallots

The objective of this study was to find out the growth and yield of shallots (Allium ascalonicum L.) with the application of mushroom media waste and goat manure. A randomized block design was used with six treatments viz. without mushroom media waste and goat manure, 25 ton/ha mushroom media waste, 20 ton/ha mushroom media waste + 5 ton/ha goat manure, 15 ton/ha mushroom media waste + 10 ton/ha goat manure, 10 ton/ha mushroom media waste + 15 ton/ha goat manure, and 5 ton/ha mushroom media waste + 20 ton/ha goat manure, and repeated four times. The observed variables were plant height per hill, number of leaves per hill, number of bulbs per hill, wet weight of bulbs per hill, wet weight bulbs per plot, dry weight of bulbs per plot, and yield per hectare. The results showed that the application of 10 ton/ha mushroom media wastes organic fertilizer + 15 ton/ha goat manure gained 1.26 kg/plot, equal to 7.7 ton/ha. The application of mushroom media waste and goat manure had the potency to reduce the use of inorganic fertilizers in supporting eco-friendly agriculture.

A prospective insight into the reproduction of Sternbergia clusiana K. Gawl.: an endangered species

Sternbergia clusiana (SC) is a bulbous plant having an alluring ornamental flower, medicinal properties, and an endangered status due to climate-change ecology. However, the methods of propagation for conserving this notable species have been neglected. The main aim of this study was to evaluate the influence of plant growth regulators (PGRs) on SC regeneration by virtue of a asexual propagation method, with the intention of preserving this endangered species from extinction. In this regard, having collected the bulbs from a wild habitat, bulbs were cut in accordance with the chipping technique. Thereafter, pieces were treated with 6-benzylaminopurine (BAP) at 250, 500, and 1000 mg·L−1, 1-naphthaleneacetic acid (NAA) at 100, 250, and 500 mg·L−1, putrescine (PU) at 50, 100, and 200 mg·L−1, BAP and NAA combination, BAP and PU combination, and a control. Pieces were then transferred into primary and terminal growing media under laboratory and greenhouse conditions, respectively. Next, the number, length, width, and weight of bulbs were determined. The greatest bulb number (2.10 counts), bulb length (26.75 mm), bulb width (16.25 mm), and bulb weight (3.13 g) were observed in the PU treatments. In addition, the results showed that even though the treated bulbs with BAP and PU combinations had preferable performance generally, the results were inconsistent. Taken together, this research indicates that utilizing asexual propagation along with PGRs, in the proper dosage, can serve as a mechanism to protect the endangered geophyte from extinction in nature.

The first factor is chicken manure consisting of 4 levels, namely: K0 = Control (without treatment), K1 = 1.83 kg/plot (equivalent to 15 tons/Ha), K2 = 2.44 kg/plot (equivalent to 20 tons/Ha) and K3 = 3.05 kg/plot (equivalent to 25 tons/Ha). The second factor is POC consisting of 3 levels, namely: P1 = 3 ml/240ml water/plant, P2 = 6 ml/240ml water/plant and P3 = 9 ml/240ml water/plant. Data analysis used analysis of variance and Duncan test. The results showed that chicken manure had a significant effect on plant height, number of leaves, number of tubers per sample, number of tubers per plot, wet tuber weight per sample, wet tuber weight per plot, dry tuber weight per sample and dry tuber weight per plot. Increasing the dose of manure will increase the growth and production of shallot plants. Chicken manure has a significant effect on plant height, number of leaves, dry bulb weight per sample and dry bulb weight per plot, but has no significant effect on the number of bulbs per sample, number of bulbs per plot, wet bulb weight per sample, wet bulb weight per plot. Chicken manure had a significant effect on the dry weight of bulbs per plot, but had no significant effect on plant height, number of leaves, number of bulbs per sample, number of bulbs per plot, wet bulb weight per sample, wet bulb weight per plot and dry bulb weight per sample.

The Effects of Different Auxin–Cytokinin Combinations on Morphogenesis of Fritillaria meleagris Using Bulb Scale Sections In Vitro

Fritillaria meleagris is a horticulturally and medicinally valuable bulbous plant that requires a period of low temperatures for proper growth and flowering. Since conventional methods of propagation are ineffective and very slow, tissue culture techniques offer an integrated approach to mass production of this valuable geophyte. In this study, we investigated the effects of various auxin–cytokinin combinations on different morphogenetic pathways in bulb scale culture. Bulbs obtained in vitro were cut longitudinally, and bulb scales were cultured for four weeks at 7 °C on MS medium supplemented with 6-benzylaminopurine (BAP) in combination with 2,4-dichlorophenoxyacetic acid (2,4-D) or α-naphthaleneacetic acid (NAA) at different concentrations in order to investigate the influence of plant growth regulators (PGRs) on different morphogenetic responses. Regeneration percentage, number of shoots per explant, shoot length, number of bulbs and number of somatic embryos were monitored weekly. After chilling, bulb scales were transferred to 24 °C, and all parameters were recorded again. Low PGR concentrations were very effective for shoot multiplication, yielding up to 5.5 shoots per explant. 2,4-D (at 2 mg/L) in combination with low BAP (0.25 mg/L) produced the highest number of bulbs (11.00 ± 0.00), while PGR-free medium was extremely effective in somatic embryo formation (13.50 ± 2.90). Detached somatic embryos and bulblets continued to grow and develop on fresh PGR-free medium. We present data demonstrating that low auxin–cytokinin concentrations and PGR-free medium provide an effective method for a combined morphogenetic pathway in F. meleagris that is suitable for large-scale propagation.

BREEDING VALUE OF SHALLOT CULTIVARS AND LOCAL FORMS IN TERMS OF ECONOMIC CHARACTERS FOR THE RIGHT-BANK FOREST-STEPPE OF UKRAINE

Purpose. To indentify the best shallot cultivars and local forms by growing period length, bulb yield, leaf productivity, and bulb weight and number per clump in the Right-Bank Forest-Steppe of Ukraine. Methods. Statistical processing, field assessments, computational and analytical methods. Results. Collection shallot accessions were evaluated for growing period lengthand, bulb weight, number and performance. Earlyripening accession ‘Sh-8’ with a vegetation period of 74 days was selected. Local form ‘Sh-1’ from the Kyivska Oblast region turned out to be the best in terms of the mean bulb weight per clump (26.7 g). Accessions from Kyivska (‘Sh-1’, ‘Sh-2’), Dnipropetrovska (‘Sh-6’, ‘Sh-9’), and Chernihivska (‘Sh-10’) Oblasts yielded the most (30.5, 25.4, 18.9, 18.1, and 19.4 t/ha, respectively). The check cultivar, ‘Lira’, yielded 15.5 t/ha. The smallest yields were harvested from the following accessions: ‘Sh-4’ (12.2 t/ha), ‘Sh-7’ (12.0 t/ha), ‘Sh-11’ (11.9 t/ha), ‘Sh-12’ (13.8 t/ha ha), ‘Sh-13 (13.2 t/ha), and ‘Sh-14’ (13.0 t/ha). Two accessions, which came from the Kyivska (‘Sh-3)’ and Dnipropetrovska (‘Sh-6’) Oblasts were found to be best adapted to the environmental conditions of the Right-Bank Forest-Steppe of Ukraine. Their Lewis’s phenotypic stability factors were close to 1. A local form from the Dnipropetrovska Oblast, ‘Sh 9’ was the worst adapted accessions, as its Lewis’s phenotypic stability factor was as high as 1.2. The maximum leaf length was recorded for accessions from the Kyivska (‘Sh-1’, ‘Sh-2’; 38.0 and 35.8 cm, respectively) and Chernihivska (‘Sh-10’; 36.2 cm) Oblasts. Conclusions. Due to this study, shallot accessions with short growing periods, great weights and numbers of bulbs and yield were selected for the conditions in the Right-Bank Forest-Steppe of Ukraine. ‘Sh-1’ sample originating from the Kyivska Oblast showed the best results in terms of the bulb weight (26.7 g) and yield (30.5 t/ha). However, it turned out to be late-ripening (86 days), and only formed on average 4 bulbs per clump. The maximum leaf length was 38 cm was. ‘Sh-8’, a local form from the Dnipropetrovska Oblast, was the most early-ripening (74 days).
