Abstract: ABSTRACT. Plant population and arrangement should be properly designed to maximize the seed yield of short-height genotypes of castor (Ricinus communis L.) in each cropping season. Experiments were performed in the in the fall-winter cropping season of 2008 and 2009 in Botucatu, State of São Paulo, Brazil, to evaluate the effects of row spacing (0.45, 0.60, 0.75, and 0.90 m) and plant population (25,000, 40,000, 55,000, and 70,000 plants ha -1 ) on agronomical traits, yield components, seed yield, and oil … Show more

“…Plant arrangement is a simple low-cost technology that can affect yield [21,92], ranging from 4200 plants•ha −1 for tall cultivars to 70,000 plants•ha −1 for dwarf varieties [73]. Castor bean plants compensate for a low population density by producing a higher number of racemes [93,94] which, however, do not increase the seed yield considering the reduced number of plants per hectare [95]. Lower plant population increases basal stem diameter and survival rate [92,94,96].…”

Lower plant population increases basal stem diameter and survival rate [92,94,96]. Seed number, a highly hereditable characteristic, is hardly influenced by environmental or exogenous factors [92].…”

“…En este sentido, el arreglo espacial, o distribución de las plantas de manera estratégica, puede ser una oportunidad para evitar la presencia de patógenos (Potts, 1990;Storkey et al, 2018). Diferentes estudios mencionan que el arreglo o disposición física de plantas es una estrategia para controlar la presencia de maleza (Evers y Bastiaans, 2016), mejorar la producción (Boyd et al, 2009) y la calidad de cultivos (De Souza-Schlick et al, 2014), así como afectar la morfología y calidad de la planta (Jirmanová et al, 2016). Investigaciones recientes sobre los compuestos orgánicos volátiles (β-farneseno, linalool, β-pineno, β-cariofileno, entre otros) generados por cultivares de crisantemo infectados por B. cinerea, proponen la planificación del arreglo de los cultivares en el invernadero como un factor a considerar ya que un cultivar que libera este tipo de compuestos podría ser la protección de otro cultivar diferente (Piesik et al, 2015).…”

“…En otro estudio, se evaluó la respuesta de diferentes cultivares de crisantemo al daño por este mismo hongo, encontrando que los antecedentes genéticos determinaron el grado de infección (Yusuf et al, 2017). Estudios de Solano-Baez et al (2013) demuestran que algunas variedades de crisantemo son (De Souza-Schlick et al, 2014), and affect plant morphology and quality (Jirmanová et al, 2016). Recent studies on volatile organic compounds (β-farnesene, linalool, β-pinene, β-caryophyllene, among others) produced by chrysanthemum cultivars infected by B. cinerea propose planning cultivar arrangements in the greenhouse as a factor to be considered, since a cultivar that releases this kind of compounds could protect a different cultivar (Piesik et al, 2015).…”
