The Cerrado has fruit species of great potential of use in commercial systems of agricultural production. They are obliged to carry out studies on the production of seedlings, contributing to a perpetuation of these species. The objective of this study was to evaluate the effect of different substrates and different doses of Basacote® on the emergence and early development of B. gaudichaudii plants. The experiment was conducted in a greenhouse in the experimental area of the Goiano Federal Institute-Campus Ceres. Experiment 1 was composed of six treatments (six compositions) and experiment 2 consisted of 5 treatments (five doses of Basacote®). The experimental design was a randomized complete block with four replicates and 12 plants per experimental plot. The variables analyzed were emergence, height, lap diameter, number of leaves, root system length, survival rate and fresh and dry matter of the aerial part and root system. The substrate composed of bovine manure + Plantmax® + soil provides better conditions for growth and development of mamacadella plants. The mamacadela seedlings do not tolerate high levels of organic matter in the substrate. For the production of Brosimum gaudichaudii seedlings the use of the 6.48 g dose of Basacote® plant-1 is indicated.

Given the high costs of agricultural production, especially due to the price of fertilisers, particularly nitrogen, the use of inoculants to supply nitrogen to soybean crops is a widely recommended practice. The objective of this study was to evaluate the feasibility of applying inoculants through seed and planting furrow in soil previously cultivated with soybean and Brazilian native “cerrado” biome soil under greenhouse conditions. Seven treatments were tested: 1) inoculation via seed (inoculant + fungicide + micronutrient), 2) treatment via seed (fungicide + micronutrient), 3) control (only seed), 4) inoculation via furrow-dose 1 (recommended dose), 5) inoculation via furrow-dose 2 (twice the recommended dose), 6) inoculation via furrow-dose 3 (three times the recommended dose) and 7) inoculation via furrow-dose 1 + seed inoculation. We evaluated plant height, fresh and dry matter weight of the aerial part and nodules, number of total, viable and non-viable nodules, number of pods per plant and grain yield. Inoculation was more effective when used in cerrado soil, but soybean performance in treatments without inoculation was higher in previously cultivated soil. Application through furrow proved to be a viable practice due to the similarity of the results obtained with the traditional application by seed.

Glyphosate Drift

ABSTRACT Chemical ripeners are frequently used on sugarcane crops in order to increase profitability. However, the drift of these products to neighbouring fields can expose susceptible non-target plants, such as sunflower, to these agents causing indirect impacts on growth and development. Therefore, this study aimed to assess the toxicity characterize possible changes in the growth of sunflower plants exposed to simulated drift of the ripeners glyphosate and trinexapac-ethyl. For each ripener, the following doses were used: glyphosate (0 (control), 3.6, 7.2, 14.4, 28.8 and 86.4 g a.e ha-1) and trinexapac-ethyl (0, 3.12, 6.25, 12.50, 25 and 75 g a.i ha-1). The effects of these products on plant height, number of leaves, leaf area, stem diameter and dry matter (leaves, stem, flower, root, shoot and total) were evaluated. We also conducted a visual analysis of symptoms of phytotoxicity after exposure. The effects of the ripeners on sunflower plants varied depending on the type of agent used and the dose. Plants treated with glyphosate showed altered growth patterns, indicating high sensitivity of these plants to the herbicide. With increasing doses, glyphosate drift promoted lower growth and development of sunflower plants and negatively affected productivity. Nevertheless, trinexapac-ethyl drift, in the evaluated doses, did not affect sunflower plants.

Phosphorus (P) and Zinc (Zn) stand out for their interactions, however, little is known about the interaction of these elements in organic substrates used in the development of plants. The objective of this work was to evaluate the extractable and total P and Zn of the enriched coconut powder substrate and the development of tomato seedlings grown on the same substrate. The work consisted of 10 treatments and 4 replicates with different doses of P and Zn. The substrate used was coconut powder enriched with nutrient solutions in a ratio of 10:1 (v/m). Then, the experiment was conducted using the enriched substrate to observe the effect of P and Zn doses on the development of tomato seedlings in trays. The height, number of leaves and the dry matter of the plants were evaluated. For the water and Mehlich-1 extractors the highest values of P and Zn were for treatments with the highest doses and only the quadratic positive effect of P did not differ statistically in the enriched coconut powder substrate. The results showed that the coconut powder used as substrate is deficient in P and Zn. The highest development of the seedlings was obtained at the doses of 74 mg L-1 P and 3.25 and 4.75 mg L-1 Zn of the substrate enrichment solution.

Eggplant (Solanum melongena) falls under the fruit species under the family of Solanaceae. It is grown widely throughout tropical and subtropical Zones in the world. It is a good source of phenolics, flavonoids, vitamins, calcium and protein. Due to its high nutritional properties, the demand for eggplant is increasing annually. However, due to limited planting space, it is difficult for the producers to increase the production in order to meet the demand. Thus, the objective of this study is to improve the growth and development of selected physiological characteristics of eggplant with chitosan and salicylic acid. The experiment was carried out in factorial randomized complete block design (RCBD) with 4 replications. This experiment was conducted at Field 15, Universiti Putra Malaysia. The plants were treated with chitosan and salicylic acid at four different rates; 0, 2, 4 and 6 ml/L for chitosan and 0, 50, 100 and 150 mg/L for salicylic acid. The treatments were applied either alone or in combination. Results revealed that the application of chitosan combined with salicylic acid influenced the physiological characteristics of the eggplant compared to the control group. Combination of 4 ml/L chitosan with 150 mg/L salicylic acid gave the highest mean values of plant height (107.13 cm), number of branches (14.91), number of leaves (136.08), total number of flowers per plant (101.8), compared to other treatments. Therefore, due to cost effectiveness and better impact on physiological characteristics the combination of 4 ml/L chitosan and 150 mg/L salicylic acid as foliar fertilizer is recommended to improve the growth and development of eggplant.

Enterolobium schomburgkii (monkey ear) is important Amazonic forest specie, being used for wood and medicinal purposes and environmental recuperation issues. Biological treatment such as Trichoderma fungus is alternative method that may improve performance of seeds germination and provide healthy seedlings. We aimed to assess effect of Trichoderma fungus on development of E. schomburgkii seedlings. Five isolates of Trichoderma spp., in the concentration of 1.0 x 107 conidia.mL-1, were assessed and applied through four methods: seeds; pre-planting substrate; post-planting substrate; and seed + pre-planting + post-planting substrate. The seedlings were produced in polypropylene bags and kept in nursery for 10 months. The experimental design was completely randomized, in a 5x4+1 factorial scheme, with 10 repetitions. We monthly assessed the plant height, collar diameter and number of leaves and leaflets. After 10 months, we assessed root length, dry matter of aerial part and dry matter of roots system. The results showed that variables were significantly influenced by Trichoderma isolates and its application modes, either individually or under interaction, except on the root length. Eight treatments boosted the plants height and five of them increased the collar diameter, compared with the control. The height of the seedlings was the variable that mostly influenced by the treatments. Application of Trichoderma in pre-planting substrate influenced the highest number of variables analyzed. Therefore, the isolates application used in this work is feasible for production of Enterolobium schomburgkii seedlings. Based on results of this experiment we do not recommended treatment of Enterolobium schomburgkii seeds with Trichoderma isolates, except using T. asperellum T09

Drug Solution

Biohumus-based preparations are widespread in agricultural production due to the high content of nutrients for plants, which improve their growth and development and, as a result, productivity. GTK indicates sufficient moisture during the growing season, but, given the nature of precipitation, in certain periods, pea plants that are sensitive to moisture, experience a lack of it in the soil and atmospheric air. The research was carried out in the farm Belousov I.V. of Starozhilovsky district. The area of plots is 40 m2. Water for the preparation of the drug solution was taken from a pond located 20 m from the pea field. The object of the study is the seed pea (Pisumsativum), which belongs to the Fabaceae family, the genus Pisum, which forms nodules on metamorphosed roots. As a result, there is a different intensity of nutrient and water consumption in ontogenesis. Watering and spraying pea plants with Humistar preparation made it possible to reliably prove high agronomic and economic efficiency in option 2: activation of enzymes, an increase in the mass of nodules on roots to 69 mg/plant, an improvement in growth to 57 cm and plant development by 5–15 days, an increase in peas yield up to 27,7 dt/ha, accumulation of dry matter in seeds up to 59 g and an increase in the level of profitability up to 80,7%.

Guarana (Paullinia cupana var. Sorbilis (Mart.) Ducke) is a species native from Amazon which has high caffeine concentration. The interactions between guarana and microorganisms in Amazonian soils need to be investigated, especially in relation to the seedling production process, due to its beneficial relationships such as biosynthesis and the supply of stimulating substances, which may result in shortening of the nursery garden or increased productivity. Thus, this research had the objective of evaluating the potential of growth caused by rhizobacteria (Burkholderia ambifaria and Bacillus sp.) in rooting of guarana seedlings. The root length, volume, dry matter of the aerial part, height, number of leaves, leaf area and dry matter of shoot were evaluated at 180 days after planting emergence. Were also determined the carbohydrate and proline content of the aerial part. The rhizobacteria did not influence the growth of the seedlings, however, the carbohydrate contents were higher when the inoculation of the rhizobacteria was carried out with the Burkholderia ambifaria bacteria in the cultivar BRS-Amazonas, with the best results. The proline levels were higher in the control treatment of the two cultivars.

ABSTRACT Although the effects of aluminum on the content and accumulation of mineral nutrients in crops have been studied, but nothing is known about its effect on the nutritional efficiency of sugarcane. Therefore, this study aimed to evaluate the effect of aluminum toxicity on nutritional efficiency, nutrient accumulation, and growth of sugarcane seedling. Sugarcane seedlings of the genotype IACSP95-5000, obtained from one-bud mini-cuttings (3 cm), were used in the test. Seedlings were subjected to treatments in a completely randomized design, with eight Al concentrations in the nutrient solution (0, 10, 20, 30, 40, 50, 60, and 70 mg L−1) and three replicates, totaling 24 experimental units. Analyses determined the contents, accumulation, and absorption, transport, and use efficiency of macronutrients, micronutrients, and aluminum, in addition to dry matter production. The results show that Al affected all variables analyzed, with a decrease in the nutritional efficiency of macronutrients and micronutrients and a drastic decrease in the accumulation of macronutrients in the aerial part, which reflected in the decrease in the dry matter of the plants. The root system was the most affected, with a decrease in growth of up to 60%. Aluminum reduced the use efficiency of nutrient in decreasing order: Ca (69%)> N (60%)> K (59%)> Mg (50%)> S (49%)> P (40%). As for micronutrients, the following decreasing order was observed: Fe (73%)> Zn (59%) = Cu (59%)> Mn (25%).

The effects of 0, 30 and 60 mM NaCl and substrates (red peat, sand or 3:1:1 [w/w] mixture of peat, sand, or soil) on vegetative growth of lulo, an Andean fruit species, during 12 weeks were studied. The experiment was carried out by using 2000 cm³ of polypropylene plastic pots under greenhouse conditions. Plant height, number of leaves and nodes, leaf area, total plant dry matter (DM), and shoot/root ratio were evaluated. With the increase of salt concentration, the plant height, the number of leaves and nodes, the leaf areas and plant dry mass DM decreased, whereas shoot/root ratio increased. Sand grown lulo plants were most affected by salinity and presented total mortality at 60 mM NaCl. On the other hand, plants held either in peat or in substrate mixture developed larger height, greater leaf and node numbers, higher leaf area and dry matter content. Shoot/root ratio in control (soil) and sand-grown plants (30 mM NaCl) was lower.

Miramar cultivado em vaso na FCAV-UNESP, Jaboticabal-SP.  O experimento foi conduzido em blocos casualizados com avaliação em parcelas subdivididas no tempo, com os tratamentos correspondentes a quatro diferentes soluções nutritivas compostas de fertilizantes comerciais (S1, S2, S3 e S4) e avaliadas em seis épocas (0, 14, 28, 42, 56  e 70 dias após enraizamento - DAE), com cinco repetições. Foram avaliados a altura de plantas; área foliar; número de folhas; diâmetro de haste; massa seca de parte aérea, raízes e total; número e o diâmetro de inflorescências; e, os índices fisiológicos da análise de crescimento. As soluções nutritivas não interferiram significativamente no diâmetro de haste, número e diâmetro de inflorescências e massa seca de raízes. Entretanto, S3 e S4 promoveram a maior altura de plantas, área foliar, número de folhas, massa seca da parte aérea e total. A partir dos índices fisiológicos, observou-se que as plantas apresentaram um crescimento vegetativo acelerado dos 14 aos 28 DAE, destacando-se as soluções S3 e S4. UNITERMOS: Dendranthema grandiflora Tzvelev., índices fisiológicos, nutrição mineral.  BECKMANN-CAVALCANTE, M.

NUTRITIVE SOLUTIONS FOR DEVELOPMENT OF POTTED CHRYSANTHEMUM  2 ABSTRACT             Although the information about nutritive solution for potted chrysanthemum is still incongruent, the objective of this work was to evaluate the effect of nutritive solutions in the development ofMiramarchrysanthemum cultivated in pots at FCAV-UNESP, Jaboticabal-SP. The experiment had a randomized block design with split-plot evaluation and treatments corresponding to four nutritive solutions consisting of commercial fertilizers (S1, S2, S3, S4) evaluated at 0, 14, 28, 42, 56 and 70 days after rooting (DAE), with five replications. The plant height, leaf area, number of leaves, stem diameter, total dry matter mass of aerial part and roots; number and diameter of inflorescences, and physiological indexes of growth analysis were evaluated. The nutritive solutions did not interfere significantly in stem diameter, number and diameter of inflorescences and dry matter of roots, although S3 and S4 provided the highest plants, leaf area, number of leaves, total dry matter of aerial part. The physiological indexes showed that plants presented an accelerated growth from 14 to 28 DAE with S4 and S3 solutions and therefore they were considered  the best solutions. KEYWORDS: Dendranthema grandiflora Tzvelev., physiological indexes, mineral nutrition.
