“…Mezzalira et al (2012) stated that this response may be related to the exposure of the plant to high temperature, which promotes higher photosynthetic activity. Similarly, Souza et al (2011) found a lower number of leaves per plant under full sun conditions, in basil seedlings grown in a commercial substrate. The interaction between substrates and environments for shoot dry mass (SDM) is shown in (Figure 9A).…”

ABSTRACT The objective of this study was to evaluate the production of watermelon seedlings irrigated with saline waters and cultivated in different types of environments and substrates. The experimental design was completely randomized with split-split plots, in which the plot corresponded to two growing environments (EN1 = full sun and EN2 = 50% shade black net), the subplot to two types of irrigation water (IW1 = 0.8 and IW2 = 2.5 dS m-1) and the sub-subplot to four types of substrates (SB1 = vermiculite + coconut fiber, SB2 = manure + soil, SB3 = carbonized rice husk + soil, SB4 = biochar + soil), with four replicates of twenty-five seeds. The variables analyzed were: emergence percentage (EP), emergence speed index (ESI), mean time of emergence (MTE), number of leaves (NL), stem diameter (SD), seedling height (SH) and root length (RL), shoot dry mass (SDM), root dry mass (RDM) and total dry mass (TDM). The EN2 treatment provided better conditions for emergence and initial growth, and EN1 was also favorable to the emergence and initial growth of watermelon seedlings, when the substrates SB1 and SB2 were used.

“…The addition of poultry manure to the substrate also increased the quality of Ocimum basilicum L. seedlings cultivated in Dystroferric Red Latosol (Souza et al, 2011). The DQI is a fundamental parameter in the evaluation of the quality of the seedlings as it combines biometric and mass production increase characteristics.…”

Organic Residues and Bokashi Influence in the Growth of Alibertia edulis

The aim of this study was to evaluate the use of different organic residues and bokashi in the substrate formulation in the initial growth of marmelo-do-cerrado. The experiment was carried out in pots under shading (50%). The following organic residues were tested: poultry manure (PM) with rice husk base, PM with wood shavings base, Organosuper®, and castor bean meal, in a control with only soil. All treatments were assessed with and without bokashi. The experimental arrangement was a 5 × 2 factorial scheme in a randomized block design with four replicates and four plants. The greatest plant height was observed when the plants were cultivated in PM with rice husk base with bokashi. The pigment contents, photochemical efficiency, biomasses and quality of seedlings were highest in Organosuper® with bokashi. We recommend the use of Organosuper® and PM with rice husk base, both with bokashi, in the growth of marmelo-do-cerrado.

“…On the other hand, Paulino et al (2011) found higher DQI value for jatropha seedlings with the commercial substrate. According to Souza et al (2011), the Dickson quality index takes into account the phytomass distribution balance. Bicca et al (2011), studying the effect of sub-strates on the formation of cabbage seedlings, realized that the substrates with higher amount of vermicompost did not favor the quality of the seedlings.…”

The aim of this work was to evaluate the initial growth of sweet pepper in different substrates and light environments. The experiment was conducted at the Federal University of Recôncavo da Bahia, in the municipality of Cruz das Almas, BA. The sowing was performed directly in 12 x 20 cm polyethylene bags and the design was completely randomized, in a 4x4 factorial scheme, with 4 replications. The substrates were: CC (commercial compound), SCC (soil (50%) + commercial compound (50%)), SV (soil (50%) + vermiculite (50%)) and SVH (soil (50%) + vermiculite (25%) + earthworm humus (25%)); and light environments: red ChromatiNet®, thermo-reflective screen (Aluminet®) and black screen (all with 50% shading) and full sun. The red screen provided higher values of height, stem dry mass, number of leaves, leaf area ratio, specific leaf area of sweet pepper seedlings; the black screen, in turn, provided higher values of root volume, leaf dry mass, stem diameter, total dry mass, root dry mass, Dickson quality index and leaf area. The quality of the seedlings produced on substrates CC and SCC was superior than that of seedlings grown on substrates SV and SVH. The treatments with screens and substrates CC and SCC favored the growth of sweet pepper seedlings.Additional keywords: Capsicum annuum L.; luminosity; shading screens. ResumoO objetivo deste trabalho foi avaliar o crescimento inicial do pimentão em diferentes substratos e ambientes de luz. O experimento foi conduzido na Universidade Federal do Recôncavo da Bahia, no município de Cruz das Almas-BA. A semeadura foi realizada diretamente em sacos de polietileno com 12 x 20 cm, foi utilizado o delineamento inteiramente casualizado, em esquema fatorial 4x4, com 4 repetições. Os substratos utilizados foram: CC (substrato comercial), substrato SCC (solo (50%) + substrato comercial (50%)), SV (solo (50%) + vermiculita (50%)) e SVH (solo (50%) + vermiculita (25%) + húmus de minhoca (25%)) e os ambientes de luz: malha vermelha ChromatiNet®, termorrefletora Aluminet® e preta (todas com 50% de sombreamento) e pleno sol. A malha vermelha proporcionou maiores valores de altura, massa seca do caule, número de folhas, razão de área foliar, área foliar específica das mudas de pimentão; já a malha preta proporcionou maiores valores de volume de raiz, massa seca da folha, diâmetro do caule, massa seca total, massa seca de raiz, índice de qualidade de Dickson e área foliar. A qualidade das mudas produzidas nos substratos CC e SCC foi melhor do que quando cultivadas nos substratos SV e SVH. Os tratamentos com malhas e os substratos CC e SCC favoreceram o crescimento das mudas de pimentão.Palavras-chave adicionais: Capsicum annuum L.; luminosidade; telas de sombreamento.
