Okra seedlings production in protected environment, testing substrates and producing fruits in field

Abstract

The okra grows well in hot weather, finding favorable conditions for development in Brazil. We evaluated the production of okra seedlings and productivity. The experiment was conducted in the experimental area of the State University of Mato Grosso do Sul, in Aquidauana. In the seedling phase we tested substrates (100% triturated cassava stems, 75% triturated cassava stems and 25% vermiculite, 50% triturated cassava stems and 50% vermiculite, 25% triturated cassava stems and 75% vermiculite and 100% vermiculite). These substrates were placed in two protected environments (nursery with black screen, 50% of shading, and aluminized screen, 50% of shading). Each environment was considered an experiment conducted in completely randomized design with eight replications. After that we realized joint analysis. In the field, a total of 10 treatments generated from combinations of environments and substrates (2 environments x 5 substrates) were distributed in a randomized block design with four replications. The average proportions of cassava stems and vermiculite may be suitable for okra seedlings. The results of shoot and total dry phytomass indicate that the aluminized screen can be recommended for okra seedlings production when the substrate with a 1:1 ratio is used. Seedlings grown on higher percentages of vermiculite anticipate production, while seedlings produced only in cassava stems tend to slow it down. The aluminized screen tends to increase the yield of okra seedlings. Average proportions of vermiculite and cassava stems for seedling production under aluminized screen, provide more fruits and yield of okra in Aquidauana.

Produção De Brócolis Em Função Das Doses De Nitrogênio E Potássio Na Fertirrigação Das Mudas

“…Existem muitos trabalhos relacionados à produção de mudas em diversas hortaliças, como abóbora (Higuti et al, 2010), alface (Domingues-Neto et al, 2016;Souza et al, 2008), beterraba (Oliveira et al, 2012), chicória Ustulim-Filho, 2013), couve-chinesa (Tessaro et al, 2013), melancia (Ramos et al, 2012), pimentão (Santos et al, 2010), quiabo (Costa et al, 2013), repolho (Cimó et al, 2017) e tomate (Rodrigues et al, 2010;Costa et al, 2012). No entanto, a maioria dos substratos estudados é produzida com materiais locais e de difícil reprodução por produtores de outras regiões.…”

Seedlings Production and Fruit Yield of Cucumber on Different Organic Substrates

“…Evaluation of the yield capacity of vegetable seedlings after substrate or container tests was performed by Modolo et al (1999), Modolo et al (2001) and Costa et al (2013b) with okra, Leal et al (2011) with lettuce and beets, and Costa et al (2012a) and Costa et al (2013a) with eggplant, and the results indicating that high-quality seedlings increase yield. In studies with 128-cell expanded polystyrene trays, Seabra Júnior et al (2004) observed that the use of trays with larger volume (121.2 cm 3 ) resulted in earlier fruit harvesting than seedlings grown in trays with smaller volume (34.6 cm 3 ).…”

Produção de mudas de pimentão utilizando fertirrigação

“…Um dos principais fatores que podem afetar a qualidade das mudas é o tipo de substrato, pois durante o período de germinação e desenvolvimento das mudas, o substrato deverá proporcionar condições hídricas e nutricionais satisfatórias. Com isto, vários estudos já mostraram que o uso de mudas com maior vigor resulta em plantas mais produtivas (Seabra Júnior et al, 2004;Leal et al, 2011;Costa et al, 2013bCosta et al, , 2015.…”
