“…Diante desses resultados, fica evidente que a idade ideal para o transplantio das mudas varia em função do volume do recipiente, sendo que em volumes menores as mudas são transplantadas mais precocemente, enquanto que em maiores volumes pode-se estender o período no viveiro. Todavia, segundo Magro et al (2011), é necessário o estudo do desenvolvimento das mudas até o final do ciclo, a fim de conhecer a influência da idade das mudas sobre a produção.…”

“…Semelhante a outras brássicas, a implantação da mostarda no campo ocorre normalmente por meio do plantio de mudas (FILGUEIRA, 2008). Essa técnica proporciona condições que favorecem o crescimento máximo, permitindo plântulas vigorosas em uma quantidade mínima de tempo (PINTO et al, 2016), além de outros benefícios operacionais, tais como economia de insumos, otimização dos tratos culturais e uniformidade de estande (FILGUEIRA, 2008;KANO et al, 2008;MAGRO et al, 2011).…”

Objetivou-se avaliar a germinação de sementes de mostarda em função da temperatura e a emergência e o crescimento das mudas sob diferentes recipientes e substratos. O experimento foi conduzido na Universidade Federal do Ceará, Fortaleza-CE, onde foi dividido em dois ensaios. No primeiro, avaliou-se as temperaturas (15, 20, 25, 30, 35 e 40 °C), sob delineamento inteiramente casualizado e com quatro repetições. No segundo, usou-se o delineamento de blocos casualizados, com quatro repetições e sob esquema de parcelas subdividida para a emergência e subsubdividida para o crescimento das mudas. Nas parcelas, avaliou-se os recipientes (450, 200 e 162 células), nas subparcelas, os substratos [S1 - 100% húmus de minhoca (HM); S2 - 60% HM, 20% fibra de coco (FC) e 20% de vermiculita (VERM); e S3 - 80% (HM), 10% (FC) e 10% (VERM) e nas subsubparcelas, as datas de avaliação (25, 32 e 42 dias após a semeadura). As temperaturas de 23,3 e 26,6ºC proporcionaram o maior percentual e velocidade de germinação das sementes, respectivamente. A emergência foi favorecida pelo substrato S3, enquanto que o maior crescimento das mudas foi obtido no recipiente de 162 células, preenchido com o substrato S1 e aos 42 dias após a semeadura.

“…Therefore, the initial differences between seedlings did not remain until the end of the cycle. Kano et al (2008) and Magro et al (2011) reported that after transplanting under favourable conditions, plants may present similar yields when transplanting seedlings with different leaf numbers, fresh and dry matter.…”

The effect of P on different plants and several growth stages are well known to scientists, but there is little information on the effect of P after transplanting the seedling until harvesting. The current study aimed to evaluate the effect of P on tomato seedling and fruit production of Paronset hybrid. Therefore, six treatments (0, 15, 30, 45, 60 and 75mg L -1 P) were evaluated in a randomized complete block design with four replications. Monoammonium phosphate (MAP) was used as P source, in addition to coconut fiber substrate. A linear increase was obtained for leaf area, seedling height, shoot and root fresh matter at 75mg P L -1 . However, yield and fruits characteristics were not affected by increasing P doses on seedlings.Keywords: coconut husk fiber, fertigation, phosphate fertilizer, Solanum lycopersicum, substrate.

“…However, if the seedlings are too young transplanted to the field, they may have an underdeveloped root system, can not withstand wind, heavy rains, and pest and disease attack. The definition of the optimal timing for seedling transplanting has been a research subject for commercial vegetables crops (Salata et al, 2011;Magro et al, 2011) and also fruit trees (Bregonci et al, 2008)…”

Survival and establishment in field of mangaba seedlings transplanted at different ages

et al. 2018

The propagation of mangaba (Hancornia speciosa Gomes) occurs mainly by seeds, a lower cost method that guarantees genotypic diversity. The great barrier is the lack of knowledge of the proper transplanting time of these seedlings. This way, the objective of this study was to evaluate the development of mangaba seedlings transplanted at different ages during the summer in Goiânia, Brazil. A randomized complete block design was used in a 2x4 factorial arrangement, with two mangaba subspecies (gardneri and cuiabenses) and four transplanting ages [45, 60, 75 and 90 days after sowing (DAS)], with four replications. Before transplanting, a destructive analysis was carried out on three plants of each subspecies to determine the biometric characteristics as a function of seedling age. The field evaluations initiated at120 DAS, evaluating monthly the seedling survival (%), plant height, stem diameter and number of live leaves per plant until 210 DAS. The biometric characteristics were not affected by the mangaba subspecies. The plant survival decreased linearly throughout the experimental period, regardless of the subspecies. The interaction age transplanting x DAS showed that at 210 DAS the seedlings transplanted later presented greater growth in height and number of live leaves. Regardless of the subspecies, the mangaba presents limitations for establishment in the field, and it is recommended the transplantio of seedlings with 90 days of age.
