Cassava Varieties

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.

Agriculture Development

This article proposes a systematic engineering for sustainable economic and ecologic development. This system is deemed to be applicable in any country of the world. The system aims to realize five important objectives: water source clearance, energy saving and emission reduction, renewable energy and organic fertilizer production, and ecological agriculture development, all in large scale and at low cost. The main conception of the new system to reach these goals is the replacement of the conventional sewage treatment approach with more efficient and more ecological process – the natural fermentation of the mixture of the urban sewage and agrarian wastes, such that water body clearance, including water de-eutrophication, green algae prevention and siltation dredging will all be accomplished at virtually a zero cost. Along with this process, the system can produce a vast amount of renewable energy and organic fertilizers, consequently ecological agriculture development in large scale can be realized. As a result, this system will greatly reduce the use of chemical fertilizers thus largely reduce the consumption of fossil energy and the related polluting emissions. This system is thus fully a circular economy model through full west-reuse processes, which ultimately will enhance our life quality with healthier food and living environment. The system is flexible and adaptable to be implemented in either small towns or megacities. The implementation and operation of this system will also benefits employment growth. Lastly, in terms of economic feasibility and profitability, millions to billions of dollars of annual revenue can be generated from the running of this system in a country.

The Impact

Introduction. Marigold (Calendula officinalis L.) is an annual plants belongs to Asteraceae family. The species is widespread in the world and have a long tradition of medicinal use with multidirectional action. Aim. The field experiments were carried out to assess the impact of genetic (cultivar) and environmental factors on yielding variability and biosynthesis of essential oil in conditions of conventional cultivation of marigold after using different methods of plantation weeding. Material and methods. The research material were two cultivars of marigold such as Orange King and Indian Prince. The following activity were tested: 1) spraying of Fusilade Forte 150 EC (1 l • ha-1), 2) spraying Fusilade Forte 150 EC (1 l • ha-1) + manual weeding, 3) manual weeding, 4) no weeding – control. The scope of the research included assessment of marigold yield (inflorescence) and determination of the essential oil contents in dry mass of raw material. Results. Regardless of the cultivar, a non-chemical methods (mechanical weeding in interrows and manual in rows) gave the highest efficiency of weed control. Similar results observed after using chemical weeding with manual weeding. In these cases the yields were at least 2.5 times higher than obtained from the control. The total yield of dry mass of inflorescence for the above methods was 6.35 and 5.53 q • ha-1 for Orange King cultivars, slightly lower result obtained for cultivar of Indian Prince (4.81 and 4.12 q • ha-1). It was also shown that the content of essential oil in the raw material ranged from 0.25 to 0.37% and was independent from the cultivar. Conclusions. The Orange King cultivar of marigold yielded better than Indian Prince in analogous methods of plantation weeding. The highest effectiveness of weed plantation was found using a non-chemical method (mechanical weeding in interrows and manual weeding in rows) and using chemical weeding with manual weeding. It was shown that the content of essential oil in the inflorescences of both examined cultivars was similar.

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.

A high level of antioxidants in organic-produced vegetables has been attributed to soil conditions; however, little is known about the relationships between antioxidants and rhizobacteria under different fertilization treatments. A pot trial for pakchoi (Brassica campestris ssp. chinensis L.) was conducted under greenhouse conditions with: (1) control; (2) chemical fertilizer; and (3) organic fertilizer. The responses of the plant, soil properties, and rhizobacterial community were measured after 45 days of cultivation. Fertilization increased soil nutrient levels and pakchoi productivity and the reshaped rhizobacterial community structure, while no differences in rhizobacterial abundance and total diversity were observed. Generally, most plant antioxidants were negatively correlated with inorganic nitrogen (N) and positively correlated to organic N in soil. The genera of Arthrospira and Acutodesmus contained differential rhizobacteria under chemical fertilizer treatment, which are known as copiotrophs. In addition, the addition of a chemical fertilizer may stimulate organic substance turnover by the enrichment of organic compound degraders (e.g., Microbacterium and Chitinophaga) and the promotion of predicted functional pathways involved in energy metabolism. Several beneficial rhizobacteria were associated with organic fertilizer amended rhizosphere including the genera Bacillus, Mycobacterium, Actinomycetospora, and Frankia. Furthermore, Bacillus spp. were positively correlated with plant biomass and phenolic acid. Moreover, predictive functional profiles of the rhizobacterial community involved in amino acid metabolism and lipid metabolism were significantly increased under organic fertilization, which were positively correlated with plant antioxidant activity. Overall, our study suggests that the short-term application of chemical and organic fertilizers reshapes the rhizobacterial community structure, and such changes might contribute to the plant’s performance.

The cherry tomato is a vegetable that is gaining great prominence commercially and, for this reason, are being developed alternatives that aim to its production of more sustainable way. Among these alternatives are the use of organic fertilizers and barriers alive. The objective of this study was to evaluate the growth and gas exchange of cherry tomato plants (Solanum lycopersicum var. Cerasiforme) cultivated under different organic fertilizations in an environment with and without alive barrier. The experimental design was randomized blocks with split-plot to the variables leaf area, leaves dry mass and stem dry mass, relative index of chlorophyll, photosynthetic rate, stomatal conductance, transpiration and water use efficiency, being the plots defined by two environments (with or without barrier) and the subplots formed by the sources of organic fertilizer (chicken manure, bovine manure and without fertilization), with five repetitions. As for the variables plant height, stem diameter, used a split-split plot design with sub-subplots formed by the seven evaluation epochs (7, 14, 21, 28, 35, 42 and 49 days after transplanting). When cultivated in alive barrier environment and under fertilization with chicken manure, cherry tomato plants presented higher growth in height and stem diameter, with no difference between the leaf and stem dry masses. In contrast, the without alive barrier environment provided an increase in chlorophyll content and increases of 55.38%, 34.49% and 46.81% in stomatal conductance, photosynthesis and transpiration, respectively. For WUE, the environment with alive barrier was higher in 18.71%.
