Great part of solid waste are deposited inappropriately near cities or in rural areas, contributing to negative environmental impacts. There are numerous forms of waste processing, one of them is pyrolysis to produce biochar and subsequent use in agricultural systems. The objective of this study was to evaluate different substrates with activated biochar (AB) and biochar (B) in substrate and its effect on the growth of passion fruit seedlings. The test was conducted in a nursery, located in Sinop/MT, May to July 2013, designed in four blocks with ten treatments: commercial substrate (CS), composed by pine bark and vermiculite 4:1; nursery substrate (NS) composed by carbonized rice husk and coconut fiber 1:1; and the eigth treatments represented were B and AB additions of 25; 50; 75; and 100% in CS, (B25, B50, B75, B100, AB25, AB50, AB75 and AB100, respectively). After 60 days sowing the stem diameter, plant height, leaf number was evaluated and at the end of the experiment the fresh and dry weight of shoots and roots, and Dickson Quality Index (DQI) were assessed. AB at concentrations of 25, 50 and 75% combined with commercial substrate showed increases in parameters fresh and dry biomass weight, height, stem diameter and number of leaves. The dose of 25% AB is presented as the best dose to be adopted in commercial crops. The sawdust processed into AB is an alternative in the production of passion fruit system and the reintegration of this raw material to the productive sector.

Areca nut is widely used as industrial raw material, both for health and cosmetics and as a source of renewable energy. This study aimed to examine the combination of seed bombatriconditioning and LEISA fertilization treatments that were effective in increasing the growth of areca nut seedlings. The research was carried out in the Wua-Wua Kendari Village, from March to July 2021. The study used a split-plot design with a completely randomized design (CRD). The main plot is seed biomatriconditioning treatment which consists of 3 treatments. While the subplots were fertilized with the LEISA technique which consisted of 6 treatments so that 18 treatment combinations were obtained with 3 replications. Observations were made on plant height, number of leaves, stem diameter, number of roots, wet weight and dry weight of shoot. Observational data were analyzed using analysis of variance, followed by the DMRT α0.05 if there was a significant effect. The results showed that seed biomatriconditioning treatment with rhizobacteria integrated with the LEISA technique was able to increase the growth of areca nut seedlings. The integration between L1R biomatriconditioning and the application of organic plus fertilizer + 100% inorganic fertilizer showed a better growth performance of areca nut on plant height, number of leaves, stem diameter, number of roots, wet weight and dry weight of betel nut which were significantly different with control and application 100% inorganic fertilizer, but not significantly different from organic plus fertilizer, organic plus fertilizer + 50% inorganic fertilizer and organic plus fertilizer + 25% inorganic fertilizer. As a conclusion, pre-planting seed treatment with L1R biomatriconditioning is very important to increase areca nut seed germination. To increase the growth of areca nut seedlings, further fertilization needs to be done with organic plus fertilizer or a combination of organic plus fertilizer + 25% inorganic fertilizer.

The highbush blueberry cultivar Bluecrop was inoculated with potential plant growth-promoting (PGPR) candidates, including bacterial inoculants Pseudomonas fluorescens (Migula) (strains Pf 5, PRA 25, 105, or 101), Bacillus pumilus (Mayer and Gottheil) (strain T4), Pseudomonas corrugata (Roberts and Scarlett) (strain 114), and fungal isolates Gliocladium virens (Miller et al., Von Arx) (strain Gl.21) and Trichoderma harzianum (Rifai) (strain T 22). Addition of G. virens to pasteurized soil increased leaf area and the number of leaves produced in a 4-month growth period, as well as shoot content of P, Zn and Cu in 1997. Treatment with P. fluorescens Pf 5 increased leaf area and stem diameter. In nonpasteurized soil, plants inoculated with G. virens had greater leaf area, stem diameter, shoot and root dry weight, and more leaves per plant. These results demonstrate the potential of G. virens for increasing growth when used to inoculate blueberry plants in the nursery or at transplanting.

Objective. We evaluated the effect of arbuscular mycorrhizal inoculation in Citrusvolkameriana Tan & Pasq plants with the application of Glomus spp Zac- 19 (G.claroides, G. diaphanum and G. albidum) to assess growth under greenhouseconditions without fertilizer application.Methodology. The evaluated treatments were inoculation with 2,4,6,8, and 10 g ofinoculum, plus a control without inoculation in an experimental design of completerandomized blocks with three replications. Variables were plant height, stem diameter,number of leaves, foliar area, dry weight, and mycorrhizal colonization.Results. A statistically significant response (p?0.01) to inoculation wasobserved, registering higher growth of mycorrhizal plants. The inoculation wasconsidered appropriate for all the levels evaluated. The outstanding treatment was 10 gof inoculum that produced plants with 110.16 cm in height for the last sampling; 38.56leaves per plant; 1.13 cm stem diameter; 35.95 g dry weight of root; 76.88 g dry weightof the aerial part of the plant; 225.03 cm 2 of leaf area per plant and 88.87% ofmycorrhizal colonization.Conclusions. The application of 10 g per plant to the roots of Citrus volkameriana fromthe Glomus Zac-19 arbuscular mycorrhizal consortium promoted the production of morevigorous plants for grafting, without the application of chemical fertilizer.

ABSTRACT Seedling quality is a key factor to achieve success in vegetable production. The present work aimed to evaluate the production of gherkin seedlings in substrate of coconut fiber fertirrigated with different concentrations of nutrients. The experimental design was completely randomized in a 3 × 5 factorial with four replications. The treatments consisted of combinations of three cultivars of gherkin (Do Norte, Liso de Calcutá, e Liso Gibão) with five concentrations of nutrients in the solution (0, 25, 50, 75, and 100%). The nutrient solution, considered standard, matches the recommended solution for melon in hydroponic systems. We evaluated the variables: chlorophyll index, shoot length, number of leaves, stem diameter, main root length, dry weight of leaves, roots, and stem, mass of total dry matter, leaf area, specific leaf area, and leaf area ratio. All variables were affected by the ionic concentration in nutrient solutions. The use of coconut fiber in the production of gherkin seedlings is more efficient with nutrient solutions in concentrations ranging from 75 to 100% of the recommended solution for melon cultivation.

A field experiment was conducted on April 3, 2016, at the Demonstration Farm of College of Agricultural Studies, Sudan University of Sciences and Technology, Shambat, Khartoum, Sudan to study the effect of some fertilizers and their time of application on growth and forage productivity of mung bean. The treatments were arranged factorially in split-plot trial with four replications. Application time was assigned to the main plot as three times of application: before sowing, with sowing and after sowing. Types of fertilizers as the sub plot including four types of fertilizers: without fertilizer (control), 50 kg ha-1 (organic manure), 100 kg ha-1 (diammonium phosphate), and 10 L ha-1 (humic acid). Different characters were measured include plant height (cm), stem thickness (cm), number of branches/plant, number of leaves/plant, fresh weight/plant (g) as well as dry weight/plant (g). The results revealed that there is a highly significant difference for types and application time of fertilizers and their interaction on plant height, number of leaves, and fresh forage and dry forage. Highly significant differences (p ≤ 0.01) were recorded in types of fertilizers and interaction between different application time and types of fertilizers for number of branch and significant difference (p ≤ 0.05) of application time for number of branch and stem diameter. There was no significant difference in types of fertilizers for stem diameter. The highest height of the plant (28.78 cm), the highest number of branches/plant (9.37), the maximum stem diameter (6.43 cm), the largest number of leaves/plant (31.69), the best fresh weight (815 kg ha-1) and dry weight (161 kg ha-1) were recorded for the treatment of 50 kg ha-1 organic manure applied after sowing.

Sunflower is considered a temperate zone crop but it can perform well under varying climate conditions. In this context, the aim of this study was to evaluate the growth of ornamental sunflower cultivars for cutting in two growing seasons in semiarid conditions. Sunflowers cultivars were sown in a randomized complete design in a split plot system, with four blocks. Six cultivars were evaluated (‘Bonito de outono sortido’, ‘Sol noturno’, ‘Sol vermelho’, ‘Jardim amarelo alto’, ‘Sunflower F1 sunbright supreme’ and ‘Sunflower F1 vincents choice’) in the main plots and two growing seasons in the subplots (GS1 – hot weather and GS2 – mild weather). Plant emergence percentage, plant height, stem diameter, number of leaves and internal inflorescence diameter were significant affected both by sunflowers cultivars and growing seasons.  Emergence speed index and external inflorescence diameter were significantly affected by the interaction of cultivars and growing seasons. The obtained results indicated ‘Sol vermelho’ for cultivation in growing seasons with mild temperatures (GS2) and 'Sunflower F1 vincents choice' recommended for both growing seasons with mild climatic (GS2) and in warmer conditions (GS1). Although all other cultivars studied have not been indicated immediately, they may be considered for cultivation, but more studies are necessary for better acclimatization.
