Allium Cepa L

Onion (Allium cepa L.) is among the most cultivated vegetable crops in the world. Afghanistan is thought to be the origin as several local and wild varieties are found in different parts of the country. Safid e Paisaye is a local variety grown in central parts of Afghanistan in the Ghorband valley. This variety has long storability and high market demand among restaurants in the region, but little research has been done to increase the quality and its availability to the market to increase its market share in Afghanistan. Conducted under supervision of Amity University Uttar Pradesh, Noida, India, at Agriculture Faculty Research Farm of Kabul University, this investigation looks at plough depth, land preparation methods, and planting date on quality and yield of onion bulb; it also studied other cultural practices including irrigation and fertilization dose and frequency. The parameters studied in this investigation include neck diameter (cm), bulb diameter (cm), neck to bulb ratio, bulb weight (gr), bulb volume (cm3), bulb density (gr/cm3), Total Soluble Solids (TSS) (Brix), firmness (Kg/cm2), marketable yield (MT/Ha), and total yield (MT/Ha). The data revealed that planting date has significant influence on bulb quality and yield of onion. The highest bulb diameter (6.95 cm), bulb weight (121 gr), bulb volume (128 cm3), marketable yield (32.54 MT/Ha), and total yield (34.24 MT/Ha) and the lowest neck to bulb ratio (0.04) were recorded for the first planting date (seed sown in nursery on 10 March - seedlings planted in field on 10 May).

A field experiment was conducted at CCS Haryana Agricultural University, Hisar to study the effect of FYM and gypsum on onion (Allium cepa L.) production under sodic water irrigation. Treatments comprised of three levels of farm yard manure (FYM) (F0- no FYM, F1- 10 t/ha and F2- 20 t/ha FYM) and three levels of gypsum (G0- nogypsum, G1- 50% neutralization of RSC and G2- 100% neutralization of RSC) in addition to control (irrigation with sodic water and no FYM and no gypsum F0G0). Results of the study showed that the seedling mortality was maximum (77.50 %) in control (F0G0) treatment, while minimum number of seedlings mortality (18.17 %) was observed in (F2G2) treatment followed by (25.17 %) (F2G1) treatment. There was significant increase in growth and yield of onion with application of FYM and gypsum. Moreover, maximum bulb yield (180.83 q/ha) was recorded in (F2G2) followed by F2G1 (152.22 q/ha) where 100% sodicity of water was neutralized by the application of gypsum and 20 t/ha FYM. Under sodic water conditions, increasing level of gypsum and FYM help in reducing the sodicity of irrigation water and thereby, increasing the yield of onion. The study concluded that in present situation of scarcity of good quality water for agricultural purposes, use of amendments like FYM and gypsum were best alternative for the best possible use of poor quality ground water and simultaneously sustain the yield of vegetable crops like onion which are sensitive to sodic water.

Allium Cepa L

Onions (Allium cepa L.) are one of the most consumed vegetable crops worldwide and are damaged by several fungal diseases in the field or during storage. Gray mold disease caused by the necrotrophic pathogens Botrytis cinerea and Botrytis squamosa is a disease that reduces the productivity and storage life in onions. However, it is difficult to control gray mold disease in onions by using physical and chemical methods. Breeding resistant onions against gray mold disease can reduce the damage caused by pathogens, reduce the labor required for control, and reduce environmental pollution caused by fungicides. However, onions have a large genome size (16Gb), making them difficult to analyze, and have a biennial cycle, resulting in a very long breeding period. Therefore, in this study, markers were developed to shorten the onion breeding period. First, random amplified polymorphic DNA (RAPD) was performed to confirm the genetic relationship between the gray mold disease-resistant and -susceptible lines through a dendrogram. In addition, the sequence characterized amplified region (SCAR)-OPAN1 marker to select resistant lines was developed using a polymorphic RAPD fragment. Second, the RNA-seq of the gray mold-resistant and -susceptible onion lines were analyzed using NGS technology. Using the RNA-seq results and DEG and GO analyses were performed, and the variants, such as SNPs and indels, were analyzed to develop a selectable marker for the resistant line. This study developed the SNP-3 HRM marker for selecting gray mold disease-resistant lines by using the SNPs present in the aldo-keto reductase (AKR) gene with high expression levels in these lines. The SCAR-OPAN1 and SNP-3 HRM markers developed in this study could be used to select gray mold disease-resistant onions in breeding programs to reduce the damage caused by gray mold disease.

Onion (Allium cepa L.) is one of the most important vegetable crops in Serbia, where it is grown on an approximate surface of 20,000 ha. During the routine quality control analysis of onion seed in 2014, fungal infection was observed in an average of 28% of the seed. The objective of this paper was to isolate, determine, and identify Fusarium sp. based on the pathogen?s morphological and molecular characteristics. Onion seed samples were collected from different localities in the region of Vojvodina. To obtain a DNA se?quence-based identification, a total DNA of the 25 isolates was extracted directly from the mycelium (~ 100 mg wet weight), with a DNeasy Plant Mini Kit (Qiagen, Hilden, Germany). Following DNA extraction, the translation elongation factor 1-alpha region was amplified by PCR with the primer pair EF1 and EF2. An amplicon of 700 bp was amplified in 25 tested isolates. Identification of one isolate was performed by sequencing the translation elongation factor EF-1? gene, which was deposited in the NCBI GenBank database under accession number KP658211 (Fusarium sp. FIESC3).

Lack Of Knowledge

Taro production in Fiji is fluctuating in a yearly basis due to presence of devastating pests and diseases. Lack of knowledge in controlling these pests and diseases and the availability of controlling resources is another problem, which farmers in Fiji are currently facing. Taveuni being the largest supplier of taro in Fiji, is experiencing problems related to mono-cropping which in cooperates problems like soil degradation, unwanted weeds and minor pests and diseases. This research article mainly focuses on pests and diseases associated with taro production in Fiji and possible control measures to help farmers in Fiji to enhance their knowledge in controlling these pests and diseases. A thorough survey of taro farmers and exporting companies in Fiji was done to evaluate the problems that have directly or indirectly affected taro production in Fiji in previous years. As shown in figure 2, Fiji has experienced the shortages of taro in the year 2010, 2012 and 2014 as a result of increasing pest and diseases. This shortage not only has affected the demand from overseas market but also farmers in terms of earning for their livelihood. If these problems are not solved at an earliest, the taro industry in Fiji may collapse resulting in greater number of problems in future.
