“…Onion yields worldwide have averaged 19.7 Mg ha -1 (Bua et al, 2017), while they are approximately 48 Mg ha -1 in Chile (FAO, 2020). González and Herrera (2012) obtained mean yields of 69.5 t ha -1 between 2001 and 2009 when using the same onion variety (Valinia INIA) in soils that share the same agroclimatic zone as the present study, which was located at the Santa Rosa experimental station of INIA Quilamapu. However, conventional management was used and the fertilizer system or rate were not mentioned.…”

“…In the present study, each treatment in 2018 was higher than the yields described by Bua et al (2017), while the fababean and oat-vetch rotation exceeded the yield described by the FAO (2020). No treatment reached the yields obtained by González and Herrera (2012); this can be attributed to low soil available P, which was less than the minimum level of 10 mg P kg -1 required by the onion crop according to Khokhar (2019). Suboptimal yields reflect factors such as low soil fertility, pests, and disease; therefore, several inputs are required to improve productivity, including adequate soil fertility management (Bua et al, 2017).…”

“…Onion contributes to farmer income and human diet, and it is highly valued for its medicinal properties (Bua et al, 2017). It is cultivated and commercialized in south-central Chile, OM and its yield is influenced by agronomic management and soil conditions that affect bulb size and weight (González and Herrera, 2012).…”

Legumes as green manure allow adding N from the air to the soil through their biological fixation. The objective was to evaluate the effect of legume crops as green manure at the beginning of the rotation on soil quality and their N input to the following onion crop (Allium cepa L. var. cepa). Five crops were sown: faba-bean (Vicia faba L.), field pea (Pisum sativum L.), oat-vetch mixture (Avena sativa L. + Vicia atropurpurea Desf.), white lupin (Lupinus albus L.), and oat as control treatment, with four replicates. Prior to sowing soil was prepared with 20 Mg ha -1 compost and 715 kg ha -1 rock phosphate. Then, at 50% grain filling stage these crops were incorporated as green manure to the soil, followed by the onion crop. Biological N fixation (BNF) by 15 N natural abundance technique parameters of green manure, yield, leaf N content of the legumes and onion, and soil bio-physicochemical properties were measured and analyzed by ANOVA and Tukey's test for mean separation (P ≤ 0.05). Faba-bean treatment had the highest BNF (388 and 369 kg N ha -1 fixed in 2017 and 2018, respectively). For onion yield, just faba-bean and oat-vetch in 2018 reached the Chilean mean yield with 54.39 and 49.08 Mg ha -1 , respectively. Control treatment yield was not significantly different. Leaf N content in onion remained within a normal range in all treatments. Adding green manure together with compost to the soil improved soil N and K contents.

“…In Pakistan decades old OPVs are being cultivated whereas little OPV and no heterosis breeding program is in place. Further, mass selection is the predominant variety improvement method in onion (González, et al, 2012) which leads to little improvement in productivity coupled with narrowing the genetic base. Not much emphasis was given on selection of better parents for OPV development and heterosis breeding except some characterization work (Mushtaq et al, 2013).…”

Exploration of genetic variation may help to select diverse parents for open pollinated variety and hybrid development program in onion (Allium cepa L.). Thirty-five onion genotypes were analyzed by two-way cluster analysis and principal component analysis (PCA) on the basis of phenotypic traits. These genotypes were grouped in five different clusters. PCA provided information for variation in genotypes on the basis of studied traits. Ten genotypes were selected from five diverse clusters and hybridized in a line × tester mating fashion. Twenty-four F1 combinations were developed and raised along-with parents for assessment of hybrid vigor, commercial heterosis and genetic correlation. Data was analyzed for morphological and biochemical traits. Maximum commercial heterosis (heterosis computed over commercial standard/check variety) for bulb yield per plot was observed in combination MKS-SGB × MKS-GBP-01, MKS-57404 × Super Sarhad and MKS-SGB × Mustang (55.77%, 36.70% and 32.90%), respectively. Maximum better parent heterosis for bulb yield per plot was in combinations MKS-SGB × MKS-GBP-01 (31.01%), followed by MKS-TEG × Mustang, MKS-57404 × Super Sarhad and MKS-SGB × Mustang (13.76%, 12.49% and 11.79%), respectively. Genetic correlation coefficient showed that bulb yield per plot showed highly significant and positive association with single bulb weight, bulb diameter, significant positive association with leaf density (number of leaves per plant), leaf width (diameter) and significant but negative association with total soluble solids. Yield per plot showed a negative association with days to maturity. Present study revealed that cluster analysis and PCA can play an important role in effective parent selection without compromising genetic diversity for development of potential hybrids for commercial exploitation.
