While treatment D gave the highest yield on the number of tillers (3.14), the number of leaves (6.97), the number of tubers (3.14). Treatment C gave the highest yield on tuber diameter (22.58 mm) and treatment A tuber length (31.48 mm).

Effect of additive intercropping with peanut and organic-silicate-biofertilizer combinations on growth and yield of shallots

Allium crops including shallot have been reported to have a high dependency on symbiosis with arbuscular mycorrhizal fungi (AMF), and have a high requirement for fertilizers. This study aimed to examine the effects of additively intercropping shallot with peanut and application of different combinations of organic-silicate-mycorrhiza-bio-fertilizer on growth and yield of several varieties of shallots. The field experiment for this study was designed according to Split Split-Plot design, with three blocks and three treatment factors, namely additive intercropping as the main plots (T0 = without; T1 = with shallot-peanut intercropping), shallot varieties as the subplots (V1 = Bima Brebes; V2 = Ketamonca; V3 = Super Philip), and fertilizer combinations as the sub-subplots (P1 = NPKS fertilizer only; P2 = NPKS+organic+silicate; P3 = NPKS+organic+silicate+mycorrhiza bio-fertilizer). Results indicated that among the treatment factors, fertilizer combination showed the most significant effects on growth and yield of shallot, and both fertilizer combinations containing silicate and organic fertilizer (P2 and P3) significantly increased yield of shallot, especially the P3 fertilizer combination, which contained mycorrhiza bio-fertilizer. Although intercropping with peanut showed no significant effects on all observation variables, there was a significant three-way interaction effect on shallot yield, which indicated different responses between varieties to intercropping and fertilizer combinations, in which yield of Ketamonca (V2) was not affected by intercropping but yield of Bima Brebes (V1) was reduced by intercropping, whereas yield of Super Philip (V3) was increased by intercropping it with peanut, especially under fertilizer combination containing mycorrhiza bio-fertilizer (P3).

Application of potassium nitrate to increase flower and seeds formation on different shallots varieties

The use of True Shallot Seeds (TSS) as an alternative planting material to produce quality shallots (Allium cepa L.), is constrained by the low formed of flowers and seeds. This study investigates the effect of potassium nitrate (KNO3) concentration on the flower and seeds formation of three shallots cultivars, and was conducted from September 2019 to January 2020 in District of West Sinjai, Sinjai Regency, South Sulawesi, at 1250 m above sea level. The experiments was set up as split plots design and provided with 3 replications. The main plot was shallots varieties (Sanren, Superpilip, and Tajuk) and the subplot was PN dosage (0, 7, 9, and 11 g per plant). Experimental results revealed that interaction of PN and shallots varieties gave a significant effect onthe average number of flower buds, number of filled flower capsules, and seeds weight. Application of 11 g PN on Superpilip varieties was able to produce the highest average number of flower buds (63), number of filled flower capsules (66.62), and seed weight (4.4 grams). This finding concludes that application of 11 g potassium nitrate per plantinduce flowering and increase seeds production of shallots, however the results will vary depend on the varieties.

Response of Trichoderma sp and shallot varieties towards plant growth and disease incidence

The main diseases that commonly attack shallots include purple blotch disease (Alternaria porri), anthracnose (Colletotrichum gloeosporioides), wilt (Fusarium oxysporum) and Stemphylium vesicarium. Purple blotch disease can cause yield losses of 3-57%. The research is aimed to measure the response of Trichoderma sp and other varieties to the growth and development of shallot disease. The study was conducted at IP2TP Margahayu Indonesian Vegetable Research Institute (IVEGRI), in August - November 2019. The research used a randomized block design (RBD) with 12 treatments and 3 replications. The treatments consisted of three varieties which are Batu Ijo, Sumenep, Trisula, Violeta 1, Maja Cipanas, and Ambasador in combination with Trichoderma and without Trichoderma. Results for the parameters of plant height and number of leaves showed that varieties that have been Trichoderma applied have reached higher height than those without Trichoderma. Ambasador showed the highest plant height (46.27 cm) and the highest number of leaves (44.16 cm). A The intensity of the purple blotch disease attacks A. porri (0.67-8,00%) and S. vesicarium (6.67-23.33%) on all varieties treated with Trichoderma lower than without Trichoderma s for the number of tillers, it is almost the same as an average of 6-7 tillers, except for Sumenep that has only 3-4 seedlings. For wet weight and dry weight per clump in the varieties applied to Trichoderma, the weight per clump is higher than those without Trichoderma, and yet wet weight and dry weight for Batu Ijo without Trichoderma application are relatively similar.

The vast utilization of wetland and dry land in the lowlands of West Sumatra Province for the development of shallots as a potential commodity in an effort to increase farmer income. Shallot is one of the leading vegetables coomodities since it has been cultivated by the people of West Sumatra in the highlands area. The availability of superior varieties of shallots produced by the Agency of Agricultural Research and Development provides many choices in shallot farming, it is necessary to test the adaptation of these superior varieties in the lowlands area. The study aimed to determine the level of adaptation of several shallot varieties in the lowlands area in Pesisir Selatan Districts, West Sumatra. The study was conducted on farmer group land in the Surantih area, Sutera sub District, Pesisir Selatan Districts from April until July 2016. The study used a Randomized Block Design (RBD) with the treatment of four superior shallot varieties namely: Katumi, Bima Brebes, Pikatan and Mentes, with 6 (six) replications. The data obtained were analyzed using variance and continued with the Duncan Multiple Range Test (DMRT). The results of research showed that: (1) the Katumi variety showed a higher harvest weight (14.00 tons/hectare) followed by the Bima Brebes, Pikatan and Mentes varieties, (2) For the Pesisir lowland dry land area, the most adaptive shallot variety was Katumi.

Effects of mycorrhiza biofertilizer and additive intercropping with peanut on growth, bulb formation, N and P contents of several varieties of shallot

Application of mycorrhiza biofertilizer to rice intercropped with soybean could increase growth and yield of rice. This study aimed to examine the effects of mycorrhiza biofertilizer application and intercropping with peanut relay-planted between double-rows of shallot on growth, N and P content, and harvest bulb number of several shallot varieties. The experiment was designed according to Split Split-Plot Design, testing three treatment factors, i.e. intercropping with peanut as the main plots (I0= without, I1= with intercropping), application of mycorrhiza biofertilizer as the sub-plots (M0= without, M1= with mycorrhiza application), and shallot varieties as the sub-sub-plots (V1= Bima Brebes, V2= Ketamonca, V3= Super Phillip). Results indicated that among the three treatment factors, mycorrhiza biofertilizer showed the most significant effects whereas intercropping did not show any significant effects. However, there were two-way interaction effects on some variables, and three-way interaction effect on harvest bulb number, with the highest average (12.8 bulb/clump) was on intercropped “Ketamonca” supplied with mycorrhiza biofertilizer whereas the lowest average (8.7 bulb/clump) was on monocropped “Bima Brebes” without mycorrhiza biofertilizer. Leaf N and P contents were also highest on peanut-intercropped shallot plants supplied with mycorrhiza biofertilizer, indicating the environmentally-friendly nature of using these treatments in increasing shallot productivity.

BGM 30 t.ha-1 produced more leaf number and fresh weight of tubers per plant higher and significantly different without BGM. Application LOF 32 L.ha-1 produce of shallot leaves more than without LOF and LOF 16 L.ha-1.

Shallot haploid breeding for sustainable production-callus induction from shallot anther tissues

Shallot is an essential vegetable crop in Indonesia, and its cultivation requires labor and capital intensive. Availability of high yielding and disease resistant shallot varieties will ensure its sustainable production. Haploid breeding should be beneficial for supporting the shallot breeding program. This study aims to identify suitable media for inducing callus growth and subsequent shoots or somatic embryo (SE) regeneration from anther tissues. In this study, successful callus induction was obtained from shallot anther but not for shoots or SE regeneration. The three different flower-sized responses were also investigated, and large flowers (5mm x 3mm) with an average anther length of 1.44 ± 0.04 mm were the best for callus induction. The microscopic observation indicated that large and medium flowers contain most bicellular pollen developmental stages, while small flowers are mostly tetrad stage. It also showed that the bicellular stage was more responsive to callus induction than the tetrad one. Moreover, the C1 medium consisted of MS basal medium supplemented with 3 mg L−1 BAP, 3 mg L−1 NAA, and 30 g/L sucrose was the best medium for inducing callus from anther explant.

Leaf Pigment, Phenolic Content, and Production of Green Shallot of Five Different Shallot Varieties

Five shallot varieties namely ‘Bauji’, ‘Bantaeng’, ‘Tuk Tuk’, ‘Rubaru’, and ‘Palasa’ were examined for their leaf pigment, total phenolic content, leaf tissue nutrient analysis, and green shallot production. The experiment was conducted in in Cikabayan greenhouse, IPB University, Dermaga, Bogor, arranged in a randomized complete block design with single factor (variety) and three replications. The observations were carried out three times in the maximum vegetative period, consisting of 20, 30, and 40 days after planting. The result showed that ‘Palasa’ had the highest leaf pigment content, such as chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid, while the anthocyanin content fluctuated between the varieties and observation times. ‘Palasa’ also had the highest sulfur content in the leaf tissues. On the contrary, ‘Palasa’ had the lowest production compared to other the varieties. Meanwhile, ‘Bantaeng’ had the highest green shallot production, total nitrogen, and total phosphorus content in the leaf tissues. Total phenolic content fluctuated in the five varieties and observation times. The highest total phenolic content was in ‘Tuk Tuk’, observed 20 days after planting. The principal component analysis (PCA) showed that the five shallot varieties formed three clusters. The first was ‘Palasa’, the second cluster was ‘Bauji’, ‘Tuk Tuk’, and ‘Rubaru’, while the third cluster was ‘Bantaeng’. ‘Palasa’ had the highest content of leaf pigment, while Bantaeng had the highest leaf production. Leaf pigment and total phenolic content changed along with the increasing plant age in all varieties.

Amelioration and variety selection to increase shallot yield in peatlands

Productivity can be achieved by improving fertility and using adaptive varieties. The research aimed to determine the effect of ameliorant types and onion varieties on soil properties and shallot yield in peatlands. The research was carried out on degraded peatland in Kalampangan, Palangkaraya, Central Kalimantan from April to September 2017. The experiment was arranged using a factorial randomized block design with four replications. The first factor was the ameliorants type (A1 = 100% manure, A2 = 50% rice husk biochar + 50% manure, A3 = 50% rice husk ash + 50% manure, and A4 = compost formulated from 40% weeds + 40% manure + 20% agricultural lime). The second factor was the shallot variety of Bima and Bauji. Observation variables included available P, exchangeable K, plant growth and yields. Manure was better than others for increasing the availability of P and K. The highest yield of shallot obtained by Bauji variety which applied ameliorant 100% manure. Shallot yields in peatland were more influenced by ameliorant type than varieties so the ameliorant was very important for the success of shallot development in peatland. The Bauji variety is quite adaptive in peatlands, so it can be recommended for larger development.

The Cost Potential of Shallot in Rasi Salai District, Sisaket Province

This research aimed to study the cost potential of shallot in Rasi Salai District, Sisaket Province in order to lead to planning on pricing, marketing, improving the quality of shallot and analyzing data of farmers and shallot production. The research findings on the general information of shallot farmers revealed that they consisted of 75% of males and 25% of females with 40-49 years of age or 50%. Most of their educational levels were 55% of primary level or lower. They grew shallot together with other crops. The Bang Chang varieties (local shallot varieties of Sisaket Province) were grown most of 75% and the other 25% of local northern verities called Hom Bua. The 70% of planting shallots were harvested from the last season and the other 30% were purchased from other farmers in the market. The shallot productivity per rai was uncertain depending on the caring, fertilizing and disturbing disease. Approximately 35% of the farmers harvested 1,200-1,500 kilograms per rai or 25%. Regarding the production cost of shallot, it was found that the average mount was 8,151.5 baht per rai with the highest amount of verities of 3,250 baht per rai or 15.2%. The cost of insecticide was 1,000 baht or 10.2% of the total cost. In addition, the least cost was transportation for 3.3% only because most merchants bought shallots at the farming sites. According to sale data, 70% of the farmers sold local verieties of Sisaket Province with average price of 30 baht per kilogram, followed by 15% of Hom Bua with an average price of 45 baht per kilogram. The average income earned by farmers in each household was different at 20,001-25,000 baht per rai

Evaluation of True Seed Shallot Varieties for Yield and Yield Components

Shallot (Allium cepa var. ascalonicum Backer) is an important vegetable crop cultivated by smallholder farmers for consumption and income generation in Ethiopia. However, scarcity of high yielding varieties as well as lack of superior planting material seriously constrains productivity of the crop. Research project was initiated aiming at studying adaption of true seed shallot for yield and components. A series of experiments were conducted using the randomized complete block design to identify the appropriate variety for production of bulb yield. The combined analysis of variance results for marketable bulb yield (kg/plot), unmarketable bulb yield (kg/ha), total bulb yield (kg/plot) and total bulb yield (t/ha). The results showed that the mean squares for main factors of genotype and year as well as interaction of genotypes x year were significant for marketable bulb yield (kg/plot). The overall marketable yield range of the shallot varieties was from 256.56- 171.49qtha^-1 and the average number of splits per plants ranged from 8- 4.72. Improved Minjar shallot variety showed its superiority in marketable bulb yield (kg/plot), total bulb yield (kg/plot) and total bulb yield (t/ha) yields as compared to other varieties. Therefore, as there was no significant yield advantage between these varieties from true seed study area, so the experiment could be repeated across locations to come up with good conclusion for recommendation.

Study on the off-season shallot seed storage using biological pesticides in Kretek district, Bantul regency, Yogyakarta special region

Farmers in the Samiran village use chemical pesticides to store their shallots. The purpose of this study was to examine the storage of shallot seeds from the off-season crops using biological pesticides. The research was conducted in March 2018 in the Ngudi Makmur farmer group. The research materials used were red onion varieties and biological pesticide of neem. The experimental design used was a completely randomized design with 3 factors with 2 replications. The factors were the type of biological pesticide (liquid and powder), storage treatment (hanging and in the basket), and the shallot varieties (Bimo, Crok Kuning, and Tajuk). The parameters observed were weight loss, damage level, growth capacity, and chemical composition. The results showed that the lowest weight loss was the storage of shallot off-season in the bucket with liquid pesticides on the Crok Kuning variety, while the high growth power test results were hanging. The treatment of biological pesticides can reduce the percentage of onion weight loss, while the use of powdered neem leaves can affect the weight loss, but it is not too high compared to the control. Hanging storage is better than basket storage because yield loss due to weight loss in basket is higher.

Effectiveness of land cultivation to control pests and diseases and increasing yield of shallots

Pests and diseases are one of the obstacles in increasing production and productivity of shallots. The study was conducted in Subak Rejasa Klod, Rejasa Village, Penebel District, Tabanan Regency - Bali Province. Research was conducted in June-November 2019, using a split plot randomized block design. The main plot is shallot varieties (V) and the subplot of the technical culture innovation (P). The main plot (V) consists of 2 treatment shallots namely Bali Karet (V1) and Lokal Tabanan (V2) and the plot consisting of 3 treatment of technical culture namely existing (P1); improvement (P2); and introduction (P3). Data on growth components and crop yields are analyzed using diversity analysis and continued with the DMRT test. Analysis of farming businesses was analyzed using B/C ratio and MBCR analysis. The results showed that Spodopthera exigua and Altenaria porri at V1 are lower than V2. The highest dry weight per hectare was obtained in the Bali Karet (V1) of 20,89 tons/ha. Introduction technology (P3) is the best innovation of dry weight-weight producing per hectare on irrigation land.. The value of B/C ratio and MBCR is 1.73 and 3.06 for introduction technology. It was concluded that introduction technology was effective as innovation of pest controllers and main diseases and were able to improve the yield of the Bali Karet variety on irrigation land.

The Effect of True Shallot Seed (TSS) Varieties and Population on Growth and Bulb Yield

Background: The purpose of this research was to evaluate the growth and bulb yield of shallot (Allium cepa L.) varieties grown by TSS with different population.Methods: This study was carried out in the low dry land at Laleten Village, Malaka District, NTT Province, Indonesia, from March to August 2018. We investigated different plant populations per planting hole using a split-plot design with two factors and four replications. The main plot was the varieties (Trisula and Bima Brebes) and the subplots were the seedling population (100, 200 and 300 plants/m2).Result: There was no interaction between varieties and population for any of the measured parameters. The population only affected the plant height at the beginning of plant growth. A high plant population (300 plants/m2) gave the highest production of single bulbs but was negatively correlated with the bulb weight. Trisula variety produced significantly more single bulbs than the Bima Brebes one. The establishment of the TSS-adapted varieties could be recommended in this area.

Effect of Nitrogen Fertilizer Rates and Intra-row Spacing on Yield and Yield Components of ‘Improved Huruta‘ Shallot Variety (Allium cepa var.ascalonicum) at Haramaya, Eastern Ethiopia

Agronomic practices for the newly released shallot variety have not been conducted in Eastern Ethiopia. To assess the effect of nitrogen fertilizer rates and intra-row spacing, a field experiment was conducted in 2017 which consisted of seven rates of nitrogen (0, 25, 50, 75,100,125 and 150 kg N ha-1) and three intra-row spacing (7.5, 10 and 12.5 cm) in factorial combination and it was laid out in a RCBD with three replications. Results of the analysis revealed that all bulb yield and yield components of the variety were highly significantly influenced by the main effects of nitrogen fertilizer and intra-row spacing. Moreover, the interaction of nitrogen fertilizer and intra-row spacing significantly influenced days to maturity, plant height, and average bulb weight and bulb dry matter. The application of 125 kg N ha-1gave high total and marketable bulb yield advantage of 32.45% (13.89 t ha-1) and 40.8% (15.47 t ha-1), respectively over the control. Plants spaced at 7.5 cm had total and marketable bulb yield advantage of 35.94% (14.54 t ha-1) and 32.83% (12.42 t ha-1), respectively over plants spaced at 12.5 cm. Therefore, intra-row spacing of 7.5 cm with the application of 125 kg N ha-1 is used for optimum yield in the study area although further research should be needed to come up with conclusive recommendation.
