“…Teniendo en cuenta planteamientos de Gómez et al (2013), la mayor producción de bulbos comerciales se logró 20 d después de iniciarse el doblamiento del follaje. El déficit de humedad en el suelo influyó significativamente en la disminución del peso y tamaño de bulbos con mayor efecto en el nivel del 50% de humedad en el suelo, acorde a Estrada et al (2015).…”

El artículo tiene como objetivo analizar factores asociados a la producción de la cebolla en la Provincia de Ocaña utilizando cuatro fórmulas de abono. La investigación siguió un enfoque cuantitativo, diseño experimental y técnicas de análisis factorial, a través de cuatro tratamientos distribuidos en subparcelas con abono orgánico casero gallinaza, estiércol bovino, pulpa de café con bagazo de caña, y, abono orgánico comercial. Resultados: cuatro factores se asocian a la producción de la cebolla en la Provincia de Ocaña, variables explicativas son zona, variedad, plagas, tecnología, y canales de comercialización, el mayor desarrollo se obtiene en parcela con abono orgánico comercial. Conclusión: amenazas, características del terreno, logística, inversión e infraestructura son factores principales. Existe diferencia significativa en efecto de fertilización entre abonos orgánicos caseros y abono comercial.

“…The growth of the polar diameter decreased from week 1 of the evaluation to week 8, with an increase in the equatorial diameter, especially when the plants entered the bulbous stage. On the other hand, from week 8 to week 11, there was new growth, accumulating the largest amount of photoassimilates, with increases in the polar and equatorial diameters (Estrada-Prado et al, 2015).…”

The bulb onion is one of the most important agricultural products in Colombia. The productive conditions of the Riego del Alto Chicamocha (Boyaca) district are a regional and national benchmark for this market. The objective of this research was to evaluate four irrigation regimes in terms of production and irrigation water efficiency in bulb onion crops. This trial was in the municipality of Nobsa, village of Dicho (Boyaca). A completely randomized design with four treatments was used: irrigation regime with 150% evapotranspiration (Evt); moisture-based irrigation regime, detected with soil moisture sensors; irrigation regime with 100% Evt; irrigation regime with 60% Evt, along with four repetitions. Starting three weeks after transplant and for 11 weeks (77 days), the polar diameter (cm), equatorial diameter (cm), root length (cm), leaf length (cm), SPAD units, stomatal conductance and irrigation water use efficiency were determined. The irrigation regime with 100% Evt had the best performance in terms of the polar and equatorial diameters and the root and leaf lengths, which were reflected in the fresh weight at harvest. The irrigation regime with soil moisture values obtained from remote sensors, with lower amounts of applied water, had better values for the transformation of water to fresh mass, with 13.64 kg mm-1.

“…Además, se utilizó semilla de cebolla certificada híbrido F1 2000 (casa comercial Hazera), una cebolla amarilla de día corto que ha mostrado cierta tolerancia al bajo contenido de humedad en el suelo (Estrada-Prado et al, 2015). the doses of chemical fertilizers in the field.…”

“…In addition, F1 2000 hybrid certified onion seed (Hazera commercial house) was used, a short-day yellow onion that has shown a certain tolerance to low moisture content in the soil (Estrada-Prado et al, 2015 to 1100 masl, and its geographical location corresponds to 8° 31' N and 71° 22' W. A composite sample of the soil was taken and sieved through a 2.36 mm in diameter mesh to prepare the seedbed. The physical-chemical characteristics of the soil are shown in Table 1.…”

The practice of producing more vigorous seedlings represents a competitive advantage at the time of transplanting a crop, and the use of combined biofertilizers are a sustainable ecological alternative. The objective of this research was to select a microbial consortium for the production of F1 2000 hybrid onion seedbeds under shade-house conditions. Five rhizobacterial strains of the genera Rhizobium (ME01 strain), Bradyrhizobium (Leu2A and YE1 strains), Ochrobactrum (ES1 strain) and Pseudomonas (Alf strain), which have shown favorable effects on pepper and lettuce seedlings. These rhizobacteria were inoculated in a mixed manner (microbial consortium) in onion as follows: Alf+ES1, ME01+ES1, ES1+Leu2A, Alf+Leu2A, YE1+ES1, ME01+Alf, YE1+Alf, ME01+YE1, YE1+Leu2A, ME01+Leu2A, using a soil from San Juan de Lagunillas-Mérida, Venezuela under shade-house conditions for 60 days. The following variables were determined: number of leaves, pseudostem base diameter, aerial and root length, aerial and root fresh and dry weight. Additionally, a CO2 assimilation curve under different light levels was carried out on the seedlings of the selected consortium to observe their photosynthetic response. The consortium ME01 + Leu2A (Rhizobium tropici + Bradyrhizobium japonicum) increased all studied variables, especially the pseudostem base diameter, essential for onion cultivation, and yielded higher seedlings CO2 assimilation rates. The use of this microbial consortium is recommended as an option for agricultural production under seedbed conditions.
