“…Although numerous studies have determined the fodder potential of C. procera (LIMA et al, 2004;ANDRADE et al, 2005;ANDRADE et al, 2008;SOUTO, 2009), Costa et al (2009) highlighted the need for more studies regarding the way it is produced. In the vegetal species domestication process, information concerning seed physiological potential, particularly germination and plantlet growth evaluations, constitutes an initial stage in developing a cultivation system.…”

-Characterizing genetic diversity based on evaluations involving germination and seed vigor, is a fundamental stage in starting the development of a cultivation system for Calotropis procera. Thus, this study aimed to estimate genetic diversity among 35 C. procera genotypes based on germination and vigor of seeds stored for 1 year. The genotypes, which originated from areas in Paraíba (Brazil), where they occur naturally, were collected and stored in March 2014. In order to evaluate the physiological potential of the seeds, two experiments were conducted between March and April 2015. The first involved a propagation test conducted in a germination chamber, while the second involved an emergence test in washed sand, performed in polyethylene trays in a screened environment under uncontrolled conditions. In both experiments, an entirely randomized design was used, with four repetitions of 25 seeds per genotype. The characteristics evaluated were germination, average daily germination, daily germination speed, the speed of germination index, the plantlet vigor index, emergence, the speed of emergence index, total length, and total dry mass. The results showed that genetic variability exists among the C. procera genotypes for variables involving germination and vigor of seeds stored for 1 year. Also, emergence, total dry plantlet mass, and germination characteristics contribute most to the genetic divergence among C. procera genotypes.

“…Em situações de seca severa, como nos últimos anos, a C. procera se sobressai em relação às espécies citadas acima, uma vez que tem a capacidade de germinar e acumular fotoassimilados mesmo quando submetida a estresses térmicos, hídricos e salinos (CARVALHO JÚNIOR et al, 2010;SOUTO et al, 2008). Outra característica importante da C. procera é sua rebrota vigorosa após o corte, conferindo a essa planta maior facilidade de manejo e obtenção (ANDRADE et al, 2008). Estudos recentes no semiárido reforçam a viabilidade agronômica da utilização dessa espécie como adubo verde em hortaliças de raízes (BATISTA et al, 2013;BEZERRA, 2012;LINHARES et al, 2011;SILVAet al, 2013).…”

“…This species remains lush and green throughout the year, forming a shrub that is fast growing and exhibits vigorous regrowth, with a production capacity of approximately 700 kg of dry matter per hectare within 60 days after cutting (Andrade et al, 2008). The content of nitrogen, phosphorus, and corresponding potassium is 17.4, 4.4, and 23.5 g kg -1 dry weight, respectively, and their C/N ratio is 25/1, which favors the mineralization process of organic matter.…”

The use of green manures in vegetable crop production systems has increased, but there is still a lack of information about the correct handling of the species for better use by culture. Two field experiments were conducted in Serra Talhada in the semiarid of Pernambuco state, Brazil, to evaluate the effects of amounts of biomass and times of Calotropis procera incorporation into the soil in the agronomic performance of the beetroot 'Early Wonder' in two growing seasons (fall and spring-summer). The experimental design was a randomized block in three replications. The treatments were arranged in a 4 x 4 factorial scheme, with the first factor corresponding to the quantities of C. procera biomass (5.4, 8.8, 12.2, and 15.6 Mg ha -1 on a dry basis) and the second to the times of incorporation into the soil (0, 10, 20, and 30 days before sowing of beetroot). The following characteristics were assessed in the beetroot: plant height, number of leaves per plant, root diameter, total productivity, commercial productivity, and dry mass of roots. The amount of C. procera as well as the time of incorporation and growing season directly influenced the agronomic performance of beetroot. Regardless of the assessed agronomic characteristics, increasing amounts, and decreasing the time of incorporation proportionally influenced the performance of beetroot. The best agronomic performance of the beetroot was obtained by fertilization with 15.6 Mg ha -1 of C. procera. The ideal time of incorporation of green manure coincided with the date of the sowing of beetroot. The cultivation in the fall season resulted in higher total and commercial productivity of beetroots fertilized with C. procera.
