CONTROLLED RELEASE FERTILIZER IN THE GROWTH OF Moringa oleifera LAM. SEEDLINGS

Abstract

Moringa oleifera presents important medicinal properties, and its seeds are used to treat water for human consumption and wastewater. The aim of the present study was to analyze the initial growth of M. oleifera seedlings in enriched commercial substrate with differing doses of controlled release fertilizer. The experimental was designed in randomized blocks, with four repetitions of 16 seedlings each. The treatment used doses of controlled release fertilizer, with 0; 2; 4; 6; and 8 kg m -3 of commercial substrate. A hundred days after installing the experiment, the following characteristics were analyzed: height of the aerial part; diameter of the root collar; length; volume; and dry mass of the roots and aerial part. Additionally, the relation between the height of the aerial part and the diameter of the root collar and the Dickson quality index (DQI) were determined. The data was submitted to analysis of variance and to the Shapiro-Wilk test to verify the normality and regression. Controlled release fertilizer at a dose of 5.37 kg m -3 of substrate is recommended for M. oleifera seedling production.

Controlled-Release Fertilizer on Growth of Melanoxylon brauna Schott Seedlings

“…Navroski et al (2016) found that cedar seedlings (Cedrelafissilis) show good growth when 5 kg m -3 of CRF are incorporated into the substrate. Rosa et al (2018) verified improvement in growth of Moringa oleifera seedling when using controlled-release fertilizer at dose of 5.37 kg m -3 substrate.…”

CONTROLLED-RELEASE FERTILIZER IN THE GROWTH OF Dalbergia nigra SEEDLINGS

“…Navroski et al (2016) found that cedar seedlings (Cedrela fissilis) show good growth when 5 kg m -3 of CRF are incorporated into the substrate. For the production of seedlings of Moringa oleifera, Rosa et al (2018) found improvement in seedling growth when they used the controlled release fertilizer at a dose of 5.37 kg m -3 of substrate.…”

“…CRFs have been researched to have the optimal release of nutrients so that the rate of release of nutrients corresponds to the maximum rate of absorption of nutrients by plants, which varies dynamically during the stages of plant development during the growing season (IRFAN et al, 2018). For the production of Moringa oleifera seedlings, Rosa et al (2018) found improvement in seedling growth when they used the controlled-release fertilizer at a dose of 5.37 kg / m -3 of substrate.…”

Plant Agronomic Features Can Predict Quality and Field Performance: A Bibliometric Analysis

“…Furthermore, in Elaeis guineensis Jacq., the DQI value is 20.0, possibly due to different factors, including the increase in the crop growth rate, the positive effect of using plant growth-promoting rhizobacteria that alter the plant hormonal balance, and the improvement of both the crop yield and the plant quality biometric attributes [25]. In medicinal plants such as Moringa oleifera Lam., controlled-release fertilisers enhance plant vigour and quality, as shown by a DQI of 18.8 at a fertilisation dose of 5.37 kg m −3 of substrate [148] (Refs. in the Supplementary Materials).…”
