The age of the seedlings in the transplant, as well as the use of biostimulants in their production, are factors that can influence the good quality of the seedlings, which is fundamental for the good development of the plant, and can affect the yield of the tomato crop. The objective of this study was to evaluate plant development and fruit yield according to the age of tomato seedlings, during transplantation, whether or not treated with the Stimulate® biostimulant. The hybrid H9553 was used, and the experiment was conducted in a randomized block design, with four replications, and ten plants were evaluated, per plot. The factorial scheme 2 x 6 was adopted, where 2 corresponds to the use or not of Stimulate®, and 6 corresponds to the age of the seedlings, in the transplant. Before transplantation, the height of the seedling, length of the root, stem diameter, number of leaves, fresh and dry mass of the aerial part and the root were evaluated at 20, 30, 40, 50, 60 and 70 days after sowing. At 78 days after transplantation, the length of the main stem, stem diameter, number of fruits per plant, total fruit mass per plant and average fruit mass were evaluated. Seedlings with seventy days show superior results for the morphological characteristics, however, this does not interfere in the yield of the culture. The use of Stimulate®, alone or in interaction with the age of the seedlings, does not influence plant growth or fruit yield.

ABSTRACT: Cultivars of the genus Nopalea are known in Brazil for being tolerant to cochineal carmine attacks, thus making the cultivation of this genus a promising alternative for mitigating the negative effects of this insect on the production of biomass. With the objectives of characterizing morphologically spineless forage cactus varieties and identify morphological characteristics that may be the focus in spineless forage cactus breeding programs, an experiment was conducted in a completely randomized block design with 11 treatments and four replications. The variety Alagoas showed the highest values of weight, area and volume of cladodes. The varieties Negro Michoacan F7 and V7, Tamazunchale V12 showed the highest values of the cladode area index, the total volume of cladodes and total fresh mass production. The varieties Negro Michoacan V7 and F7 presented the highest water use efficiency and dry mass yield. Cladode volume showed the highest correlation coefficients with the fresh weight of cladodes. Aiming the release of varieties for biomass production, varieties Negro Michoacan F7, V7 and Tamazunchale V12 may substitute the Miúda variety. The number and cladode area index may be used as criteria for selection of superior varieties in breeding programs.

Abstract: Some desiccation techniques for harvesting wheat may affect seed quality. The objective of this study was to evaluate the effect of different desiccant herbicides applied to the wheat crop and their effects on the production and seed quality. The experiment was conducted with cultivar COODETEC 150 (CD 150) in two sites in Palotina (Paraná state, Brazil) with a randomized block design consisting of 7 treatments (desiccation herbicides) and 4 replications. Desiccation was realized when 50% of the plants were in stage 80 with seeds in powdery or mass consistency. The variables analyzed were percentage of moisture content after harvest, Yield, hectoliter weight, mass of 100 seeds, vigor, germination, fresh mass of seedlings, dry mass of seedlings and root length. The herbicides carfentrazone-ethyl and clethodim were the ones that promoted greatest reduction in vigor. The herbicide paraquat caused reduction in seedling length. There was a reduction in the mass of 100 seeds for glufosinate-ammonium, clethodim, diquat and carfentrazone-ethyl. Glufosinate-ammonium, paraquat, glyphosate, clethodim and diquat caused reduction in yield. Desiccation of Cultivar CD 150 at stage 80 is not recommended, since plant Yield and physiological seed parameters were adversely affected by herbicides.

ABSTRACT The Panicum maximum species (cv. Mombaça) is a forage plant well adapted to the different edaphoclimatic conditions found in Brazil; however, it requires high nitrogen fertilizer doses to ensure high yields. The present study aimed to assess the inoculation effect with associative diazotrophic bacteria strains on the yield and bromatological characteristics of the Guinea grass. A randomized block design was used, consisting of 25 treatments, being 23 of them inoculated with diazotrophic bacteria and two without inoculation (one with and the other without mineral nitrogen), with four repetitions. The analyzed variables were stem diameter; leaf width and length; leaf, stem and root dry mass yield; crude protein; acid and neutral detergent fibers. There were no differences among the treatments for root dry mass, stem diameter and acid detergent fiber. For the remaining variables, a positive effect of the inoculation with diazotrophic bacteria was observed, particularly for the following Unifenas strains: 100-06, 100-13, 100-26, 100-30, 10-35, 100-54, 100-69, 100-71 and 100-94. This reveals the potential of these bacterial strains for use at the sustainable production of the Guinea grass with a reduction in the use of nitrogen inputs.

The tomato crop is considered of great socio-economic importance in the world, feeding millions of people daily. This crop is considered strategic because its production is diverse in the world, being produced by large agro-industries, moving a rich productive chain. This work aimed to evaluate the production of tomato seedlings as function of different substrates, and to comprehend the interrelation of characteristics through linear associations. The experimental design was randomized blocks, using one tomato cultivar, Santa Cruz Kada, in 32 repetitions for each treatment. The treatments consisted of several substrates such as carbonized rice husk, grape husk (S10), coconut fiber, and commercial substrate (Bioplant®). The experiment was carried out in a greenhouse using pots. The characters measured 25 days after sowing were: stem diameter, number of leaves, shoot length, root length, green mass of root, green mass of shoot, dry mass of shoot, and dry mass of root. The analysis of variance was performed and the characters that presented significance were compared by the Duncan test at 5% of probability. Subsequently, Pearson’s linear correlation was individually performed for each substrate. The results showed that commercial (Bioplant®) and grape skin substrates were the most suitable for production of tomato seedlings cv. Santa Cruz Kada. The characters of stem diameter, number of leaves, shoot length, green mass of root and green mass of shoot revealed significant correlations; however they differently behaved in the substrates.

The acerola tree is one of the most promising fruit trees of the Brazilian fruit sector, demanding the development of studies that indicate the proper conditions to improve its production under adverse conditions. Consequently, our purpose was to evaluate the growth of Malpighia emaginata D.C in several substrates and under ascending levels of irrigation water salinity. The experiment was conducted in a 4 × 5 factorial scheme randomized block design, which comprised four substrates (S1 = soil; S2 = soil with a 10% addition of cattle manure; S3 = soil with a 10% addition of organic compounds; and S4 - soil with a 5% addition of cattle manure and a 5% addition of organic compounds) and five CEa salt levels (0.3, 1.0, 1.7, 2.7, and 3.5 dS m-1). The plant height and stem diameter variables were not affected by the studied factors. The interaction between salinity and the substrates affected the root growth and the build-up of the plants’ fresh and dry biomass, resulting in the increase of the values obtained by the substrates containing manure and organic compounds. The seedlings’ quality, represented by the height/stem diameter and aerial part/root dry mass ratios, and by the Dickson quality index, indicated that the plants produced in the substrates 2 and 3 were more vigorous.

The objective of this study was to identify the hybrids of sorghum most suitable for the production of silage in the semiarid regions of northeastern Brazil. Twenty-three hybrids were evaluated in a randomized block design with three replicates. The dry mass yield; dry mass of leaf, stem, panicle, grains, and senescent matter; and chemical composition of the plant were evaluated. The pH, ammoniacal nitrogen (N-NH3), and chemical composition of the silage were also assessed. The hybrids 947252, FEPAGRO 18, 12F042226, and SF 11 performed best in terms of morphological characteristics, with the highest mass of leaves and grains. The hybrid FEPAGRO 19 had the highest dry matter value (443.3 ± 17.0 g kg-1), whereas the hybrid 12F042496 had the lowest value (271.3 ± 17.0 g kg-1). The dry matter (DM) content of the other hybrids was within the recommended values for silage production (280 to 400 g kg-1). High levels of crude protein were observed in the grouped hybrids 12F042496, 947254, and 12F042422. The hybrid 12F042496 had the highest neutral detergent fiber content. The hybrids 9929036, 9929030, 9929012, 947254, 947072, PROG 134 IPA, 12F042226, 12F042422, and BRS 506 had pH values ranging between 3.8 and 4.2, indicating good quality silage. Overall, the sorghum hybrids 9929030, 12F042224, 12F042150, FEPAGRO19, and FEPAGRO11 had the best growth and production characteristics, and plant and silage chemical composition, and are thus recommended for the production of silage in the semiarid of northeastern Brazil.

The present work aimed to evaluate the influence of use, as well as to determine adequate doses in organic fertilization of the bokashi type in the cultivation of two basil (Ocimum basilicum L.) cultivars. Seeds from the collection of the Floriculture Laboratory of the Phytotechnics Department of the Federal University of Ceará were used. The treatments used were arranged in a randomized block design (RBD), arranged in a 2x5 factorial scheme, consisting of two cultivars of basil (Genovese and Anão) and five doses of Bokashi, namely: 0, 3, 6, 9 and 18 g.L-1. Plants that received no dose (0 g.L-1) served as a control treatment. Each treatment contained 5 repetitions, with the plot consisting of 7 pots, one plant per pot, the useful unit a pot with a basil seedling. From the transplant, applications of bokashi were started in doses of 0, 3, 6, 9, and 18 g.L-1 in both cultivars. Both applications were performed every 20 days after the first application of Bokashi. Fivety five days after transplantation in the final pot, the following variables were analyzed: plant height, stem diameter, fresh and dry mass of the aerial part and the root. The 9 g.L-1 dose of Bokashi showed the best results for the variables analyzed for both cultivars, in addition to being efficient when compared to the control, in which the vegetative growth was incipient.

The objective of this work was to evaluate the influence of cell sizes used for strawberry plug production in trays compared to bare root transplants, regarding initial plant size, harvest timing, and total strawberry fruit yield. Plug transplants were produced from runner tips rooted in trays with cell sizes of 26.5, 50, 100 and 150 cm³ filled with Plantmax HA organic substrate. Bare root transplants (control) were produced in a closed soilless system using sand as substrate. A randomized block design was used, with four replicates with 16 plants per plot. Bare root transplants and plug transplants from 100-cm³ cells had larger crown and higher leaf and root dry mass. Early fruit yield was higher in plants propagated from plugs than in those propagated from bare root transplants. Spring and total fruit yield did not differ among treatments, with an average yield of 435 and 874 g per plant, respectively. Earlier strawberry fruit yield was obtained by using plug transplants, even from trays with small cells of 26.5 or 50 cm³.

Experiments were conducted on valerian (Valeriana officinalis L.) grown under glasshouse conditions to evaluate the effect of Cadmium (Cd) on plant morphological characteristics and Cd uptake. Valerian plants were grown in pots containing a uniform mixture of either moderately acidic or slightly alkaline substrate consisting of peat and perlite (1:1 v/v) over two periods. Pots were arranged in a completely randomized block design within two groups (moderately acid substrate and slightly alkaline substrate) with four Cd treatments (0, 1, 2 and 5 mg Cd L-1) and six replications per treatment. Cadmium was applied as CdSO4*8/3H2O. No visual symptoms of toxicity or nutrient deficiency were attributed to Cd application irrespective of the growth stage or substrate in either experimental period. Cadmium did not affect the dry mass of shoots or roots. Cd concentration in both shoots and roots increased with increasing Cd application, indicating valerian to be a Cd accumulator with accumulation occurring mainly in the roots both in moderately acidic or slightly alkaline substrates. The amount of Cd extracted by Diethylene triamine penta acetic acid-triethanol amine (DTPA-TEA) increased with increasing Cd doses and significantly correlates with the Cd concentrations within the shoots and roots indicating that this extractant could be used to predict Cd concentrations within the plant parts.

ABSTRACT The use of cultivars appropriate to the soil and climate characteristics of a region provides farmers with security by facilitating credit for crop financing and improving product prices in local commerce. The objective of this work was to evaluate the agronomic performance of “Contender” and “Amarelo Japonês” green bean bush cultivars grown in the Cerrado in terms of water replenishment (RH) of 25, 50, 75, 100, and 125% of evaporation using the Piché evaporimeter. The experiment was carried out in the experimental area of the State University of Goiás, on the Ipameri Campus. The experimental design was a randomized block design. Sowing was done in May 2017, with treatments distributed in a split-plots scheme with water replenishment in plots and cultivar subplots with 3 replications. The analyzed variables were: height; stem diameter; leaf number; leaf area; number of inflorescences; number of flowers; fresh and dry mass of the plant; number, length, diameter, fresh and dry mass of the pods. The different water replenishment rates increased the mean plant height, stem diameter, number of pods per plant, number of bean seeds per pod, and number of bean seeds per plant in the cultivars “Amarelo Japonês” and “Contender.” Water replenishment of 125% produced higher development and better agronomic performance in the two cultivars than the other rates.
