Seedlings of cassava varieties are responsive to organic fertilization

In Brazil, there is already a recommendation for the production of cassava seed-cuttings for the production of seedlings originated from micropropagation, which may be extended for the production of seedlings obtained from cuttings from healthy plant stems, in order to avoid the spread of diseases. Therefore, it is essential to establish adequate cultivation substrates of easy acquisition which may stimulate the growth of seedlings, both to reduce the nursery period, as well as the seedling’s production costs. The objective of this work was to evaluate the effect of organic fertilizers made from bovine and goat manures, and tree pruning residues, to produce seedlings of three cassava varieties. The plots were set in a completely randomized design, with six replicates. The treatments consisted of three cassava genotypes (BRS Formosa, BRS Tapioqueira and BRS Kiriris) and five proportions of organic fertilizer: soil (0: 100, 20:80, 40:60, 60:40 and 80:20). The evaluations were performed 30 and 45 days after planting (DAP). There were isolated effects for shoot dry mass, total dry mass, leaf area and number of leaves. Interactions were verified for root length, chlorophyll a and total chlorophyll index, root dry mass and shoot dry mas/root dry mass ratio 45 DAP. The organic fertilizer stimulated the initial growth of cassava seedlings in the three varieties studied in the proportion of 50% of organic fertilizer and 50% of Latosol. Varieties BRS Formosa and BRS Kiriris showed the highest Dickson Quality Scores. Genotypes reacted efficiently to organic fertilization and can be propagated on these easily acquisition cultivation substrates.

The application of Trichoderma fungus can be used to obtain seedlings of higher quality for plantations. The objective of this study was to evaluate the effects of Trichoderma isolates on the germination and initial growth of açaí seedlings. Two trials were set up. In the laboratory, the seeds were inoculated in suspensions prepared with each of the isolates for 24 h, and they were arranged in trays containing filter paper in a completely randomized design with five replicates containing 50 seeds each. For the control, the seeds were submerged only in water. Part of the seedlings resulting from seeds treated and not treated with Trichoderma were transferred to bags containing forest soil and were submitted to seven modes of application of Trichoderma and kept in a nursery. The speed of germination and hypocotyl were not influenced by the biological treatment. The application of the different Trichoderma isolates positively influenced the height, collar diameter, number of leaves, root size, leaf area and root, and aerial part dry mass of the açaí seedlings. The application of the Trichoderma isolate TAM01 on the preplanting substrate and biweekly applications on the postplanting substrate was the combination that most positively influenced the development of açai seedlings.

In order to meet the growing market of gerbera, it is necessary to develop studies that maximize its production, especially using organic fertilizer. In order to assess the nutrition and growth of potted gerbera conducted with mineral and organic fertilization, an experiment in a greenhouse was done, located at Western Paraná State University, Brazil. The experimental design was made in randomized blocks, with four replications and five treatments. The treatments were defined according to the source of fertilization, mineral (NPK) or organic. The organic fertilization were obtained by diluting in water four organic compost of poultry slaughter waste, obtained from in the composting process, in order to adjust electrical conductivity. The solution of the compost was used as organic fertigation, making the organic treatments. The liquid organic fertilizer, as well as irrigation of mineral treatment, was performed manually once a day. At the end of vegetative and reproductive periods, the levels of N, P, K, Ca, Mg and Fe were quantified in the plant tissue. At the same time, biometric parameters were assessed (number of leaves, plant diameter, leaf area, dry matter of aerial parts, number of heads, inflorescence dry matter, stem height, head diameter and diameter stem). The liquid organic fertilizers, obtained by composting procession of poultry slaughter waste, can be used as alternative source for potted gerbera nutrition, since they provide better or higher culture growth than the mineral fertilizer.

ABSTRACT The objective of this work was to evaluate the initial growth of Bauhinia variegata L. when inoculated and fertilized with different proportions of organic compost. The experiment was performed in greenhouse in a completely random factorial (2 x 5) + 1 design, with 9 replicates, constituted by the presence or absence of inoculation, five proportions of organic compost:soil (0:100, 20:40, 40:60, 60:40 and 80:20; v/v) and one additional treatment with chemical fertilization without inoculation. Ninety days after sowing, the plant height, stem diameter, number of leaves, radicular length, dry mass of the aerial portion, dry mass of roots, total dry mass, Dicksosn's quality index (IQD), contents of nitrogen and carbon and the C/N ratio of the dry mass of the aerial portion, were evaluated. The inoculation with diazotrophic bacteria stimulated growth in height, stem height/diameter ratio, dry mass of the aerial portion, dry mass of roots, total dry mass and the foliar contents of nitrogen and carbon in seedlings of B. variegata L. Seedlings grown using organic compost showed better development when compared to seedlings grown only in soil with or without chemical fertilization. Seedlings grown with formulated substrate at a proportion of 16:84 (organic compost:soil + inoculation) exhibited higher IQD, therefore, this constitutes the recommended proportion for production of B.variegata L. seedlings.

Irrigation Levels

The sprouting phase of cassava is critical for the establishment of the plant, with this phase being dependent on soil moisture. As such, this study evaluated the effect of different irrigation levels on the initial growth of cassava cv. Mossoró in semi-arid conditions. The experiment was conducted under completely randomized design conditions with 5 replications. The treatments in pots containing one plant per experimental unit consisted of 5 irrigation levels, 0, 25, 50, 75 and 100% of the reference evapotranspiration (ETo, mm day-1), which corresponded to totals for the experimental period of 11.20; 42.15; 73.09; 104.03 and 134.97 mm, respectively. At 30 days after planting, the number of leaves and stems, as well as the dry mass of the shoot and the root had increased sharply for irrigation levels up to 73.09 mm. For higher irrigation levels there was a tendency for plant growth stabilization; however, above 104.03 mm there was a decrease. Shoot and root dry mass ratio showed severe water stress at the 11.20 mm level, being more damaging to root growth. Plant height showed a positive linear trend as the level of irrigation was increased, as opposed to water use efficiency. Therefore, irrigation with 50% replacement of ETo (73.09 mm) provided the best conditions for early growth of cassava.

The excess of salts may compromise the growth and physiological functions of plants, but the use of bovine organic fertilizer can mitigate these effects. It was intended was to evaluate the saline stress in soil with and without bovine organic fertilizer on the initial growth, the accumulation of biomass and the gas exchanges of the okra culture. The test was conducted at the UNILAB’s experimental farm, in Piroás, in Redenção – CE city. The treatments were distributed in a completely randomized design with five replications, in a 5 x 2 factorial concerning five irrigation water salinity levels (1.0; 2.0; 3.0; 4.0 and 5.0 dS m-1), in the presence and absence of bovine organic fertilizer. Plant height, stem diameter, root length, a dry mass of shoot, photosynthesis, transpiration and stomatal conductance were evaluated. The bovine organic fertilizer promoted better means in initial growth and biomass in okra plants compared to the control treatment, thus showing efficiency in the attenuation of the salts present in irrigation water. The increase in the saline concentration of the irrigation water reduced the gas exchange (photosynthesis, stomatal conductance and transpiration) in okra plants. Nonetheless, in smaller proportions in the soil with the bovine organic fertilizer.

Organic fertilizer is capable to decrease the use of synthetic fertilizer due to release of plant nutrients and improvement of other soil properties. The objective of this experiment was to compare the growth and yield of green mustard as affected by cattle manure and litter compost. The experiment was conducted employing Completely Randomized Design with 8 treatments. Treatments included litter compost and cattle manure at rate of 25 Mg ha-1 and 15, 20, 25 Mg ha-1 with addition of 1.85 g nitrogen fertilizer per plant, respectively. Each treatment was replicated 5 times. Soil used in this experiment was Ultisol collected at depth of 0-20 cm. Five kg of soil was mixed with organic fertilizer according to each treatment and placed in 10 kg polybag. Green mustard was planted to each polybag. Nitrogen fertilizer was applied a week after planting. The experiment revealed that application of litter compost and cattle manure at rate 25 Mg ha-1 with additional nitrogen fertilizer resulted in higher green mustard fresh weight per plant and number of leaves. On the other hand, application of both organic fertilizers at rate of 25 Mg ha-1 without addition nitrogen fertilizer as other treatments did not provide significant differences on most variables observed. This indicated that application of organic fertilizer is able to reduce synthetic nitrogen fertilizer for green mustard production.
