Sweet sorghum is a special purpose sorghum with a sugar-rich stalk, almost like sugarcane. The objective of this work was to evaluate the phenotypic stability and adaptability of sweet sorghum genotypes, in different Brazilian regions, for the production of bioethanol. Twenty-five sweet sorghum genotypes were evaluated in 10 environments distributed in the Southeast, Midwest, Northeast, and Southern regions of Brazil. The experimental design was a randomized complete block design with three repetitions. The following agroindustrial traits were evaluated: fresh biomass yield (FBY), total soluble solids content (TSS) and tons of Brix per hectare (TBH). The adaptability and stability analyzes were performed with the methods GGEbiplot and Annicchiarico methodologies. The Annicchiarico and GGEbiplot adaptability and stability study methods presented satisfactory and consistent results and can be used separately or together in sweet sorghum breeding programs, and B005 and B008 sweet sorghum genotypes presented superior performance, with similar classification in both methods studied.

This study evaluated the effects of the sugarcane borer Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) on cultivars of sweet and biomass sorghum for the selection of resistant cultivars. The present work consisted of two trials, with natural pest infestation. In the first one, 10 sweet sorghum cultivars were analyzed for the following variables: plant height, number of healthy and damaged internodes, gallery position and size, stem infestation level and soluble solids content (°Brix). In the second trial, it was analyzed 16 genotypes of high biomass sorghum, with the same variables above mentioned, in addition to the lignin, cellulose and hemicellulose contents. Among sweet sorghum genotypes evaluated, the genotype CMSXS647 stood out due to the traits: plant height, infestation level, gallery size and soluble solids content. Among the sorghum genotypes evaluated, CMSXS7030, CMSXS7012 and CMSXS7028 presented ideal characteristics for infestation level, plant height and number of lignocellulosic compounds. Such information, in addition to supporting the bioenergy sorghum breeding program, will assist in integrated pest management for sorghum cultivation.

Among the problems faced by the melon crop in the state of Rio Grande do Norte, northeastern Brazil, the effect of water and soil salinity is considered one of the key factors to limit fruit production and quality. The aim of this work was to study the effects of using irrigation waters with different salinity levels on yield and quality of fruits of the yellow melon hybrid Mandacaru. A randomized complete block design was used with five treatments (irrigation water salt concentrations: 0.54, 1.48, 2.02, 3.03, 3.9 dS m-1) and four replications. The effects of these concentrations were evaluated through, number of marketable fruits per plant, marketable and total fruit yield, average marketable fruit mass, soluble solids content and pulp firmness. Increment in water salinity level negatively influenced crop yield. The 3.9 dS m-1 salinity level caused yield losses of 20.31%, due to the reduction of fruit number per plant. The highest soluble solid content and the highest pulp firmness values were estimated to occur at salinity levels 2.09 and 3.5 dS m-1, respectively.

Abstract: The objective of this work was to evaluate the potential per se of male-sterile and fertility-restorer lines of sweet sorghum (Sorghum bicolor), as well as to detail the heterosis manifested for some traits directly or indirectly related to ethanol production, accumulation rate, and predictability. Evaluations were performed for 20 genotypes, of which 4 are fertility-restorer lines (R), 3 are male-sterile lines (A), and 12 are experimental hybrids (H) resulting from the partial diallel cross between lines A and R, besides a commercial hybrid CV198 used as a check, in four harvest seasons. The experiments were carried out in the municipalities of Lavras and Sete Lagoas, in the state of Minas Gerais, Brazil. The measured traits were plant height, green mass production, juice extraction, total soluble solids content, and megagrams of Brix per hectare. The male-sterile A1 and the fertility-restorer R1 and R3 lines show the best potential per se, considering all traits and their accumulation rate and predictability over harvest times. Heterosis is significant for all traits. The H11, H13, H14, H21, H22, and H33 hybrids are promising because of their better performance per se and higher heterosis.

Foram avaliadas a taxa de alongamento das folhas, o número final de folhas no colmo, a taxa de surgimento de folha, filocrono e taxa de elongamento de colmo. As variáveis não apresentaram interação tripla significativa entre genótipo, espaçamento de entrelinhas e época de semeadura. O genótipo BRS 506 apresentou número de folhas acumuladas, taxa de alongamento de folhas nas épocas de semeaduras constante. O atraso na época de semeadura resulta em menor número de folhas acumuladas e taxa de elongação do colmo para o Fepagro 19. O filocrono para o espaçamento entrelinhas 0,70 m é inferior ao de 0,50 m. Os genótipos estudados estão aptos para a produção na região, desde que a semeadura ocorra no mês de outubro. Palavras-chave: alongamento foliar, filocrono, graus-dia, índice Haun, Sorghum bicolor. LEAF MORPHOLOGY OF SWEET SORGHUM CULTIVATED IN DIFFERENT ROW SPACINGS AND SOWING DATES ABSTRACT - The objective of this work was to evaluate the morphogenic characteristics of the main stem of sweet sorghum genotypes in different spacing between lines and sowing times. The experimental was carried out in a randomized complete block design in a trifactorial scheme (2x2x3), with two sweet sorghum (BRS 506 and Fepagro 19), two spacing between lines (0.50 m and 0.70 m) and three sowing seasons (October, November and December), four replications and two years of cultivation. The leaf elongation rate, the final number of leaves in the stem, the leaf appearance rate, phyllochron and shoot elongation rate were evaluated. The variables did not present significant triple interaction between genotype, spacing between rows and sowing time. The genotype BRS 506 presented a number of accumulated leaves, leaf elongation rate at constant sowing times. The delay in sowing seasons results in a lower number of accumulated leaves and the elongation rate of the stem for genotype Fepagro 19. The phyllochron for the 0.70 m line spacing is less than 0.50 m. The genotypes studied are suitable for production in the region, as long as sowing occurs in October.Keywords: leaf elongation, phyllochron, degree-days, Haun index, Sorghum bicolor.

The fossil energy sources used in the world are gradually decreasing and limited. Fossil fuels cause environmental pollution, and the unit price is constantly increasing. For this reason, demand for cheaper and renewable energy sources that do not pollute the environment is increasing day by day. The sweet sorghum plant has attracted attention in recent years with its high biomass yield, sugar content and bioethanol yield. In this study, it was aimed to determine the bio-fuel potential of some sweet sorghum genotypes in semi-arid climatic conditions. The experiment was set up in randomized complete block design with 4 replicates. Research was carried out in 2015 under Harran Plain (36o 42’ N and 38o 58’ E) second crop conditions, Sanliurfa, Turkey. In the study 49 genotypes of sweet sorghum were used. Stalk yield, juice yield, syrup yield, brix, sugar yield and theoretical ethanol yield were determined in the study. Significant differences were found between the genotypes for tested characteristics (P≤0.01). Stalk yield ranged from 7110.0 kg da-1 to 24262.5 da-1, juice yield from 2550.0 L da-1 to 12187.5 L da-1, syrup yield from 291.4 L da-1 to 2242.5 L da-1. Also, brix value varied between %7.0 and %18.87, sugar yield between 247.7 da-1 and 1906.1 da-1, Theoretical ethanol yield between 131.9 L da-1 and 1014.8 L da-1. Considering to stalk yield, juice and syrup yield, brix, sugar yield and theoretical ethanol yield; Nebraska sugar, Topper 76, Smith, M81E and Corina genotypes were found as the best. As a result of research, 21 genotypes with better performance than the others were selected for further studies.

The genotype and environment interaction influences the selection criteria of sorghum (Sorghum bicolor) genotypes. Eight sweet sorghum genotypes were evaluated at five different locations in two growing seasons of 2014. The aim was to determine the interaction between genotype and environment on cane, juice, and ethanol yield and to identify best genotypes for bioethanol production in Kenya. The experiments were conducted in a randomized complete block design replicated three times. Sorghum canes were harvested at hard dough stage of grain development and passed through rollers to obtain juice that was then fermented to obtain ethanol. Cane, juice, and ethanol yield was analyzed using the additive main effect and multiplication interaction model (AMMI) and genotype plus genotype by environment (GGE) biplot. The combined analysis of variance of cane and juice yield of sorghum genotypes showed that sweet sorghum genotypes were significantly (P<0.05) affected by environments (E), genotypes (G) and genotype by environment interaction (GEI). GGE biplot showed high yielding genotypes EUSS10, ACFC003/12, SS14, and EUSS11 for cane yield; EUSS10, EUSS11, and SS14 for juice yield; and EUSS10, SS04, SS14, and ACFC003/12 for ethanol yield. Genotype SS14 showed high general adaptability for cane, juice, and ethanol yield.

 RESUMO - O rendimento de cultivares de sorgo sacarino em planta de primeiro corte e na rebrota tem sido estudado para viabilizar o cultivo com menores custos de produção. Entretanto, dados qualitativos sobre a qualidade de caldo e rendimento de etanol entre safra principal e rebrota são escassos. Objetivou-se com este trabalho comparar genótipos de sorgo sacarino quanto à qualidade industrial e avaliar o efeito do tipo de colheita e biomassa processada no rendimento industrial para produção de etanol. Foi conduzido um experimento em blocos ao acaso com três repetições em esquema de parcela subdividida, sendo as parcelas constituídas por 20 genótipos de sorgo e as subparcelas pelos tipos de amostras processadas ou colheitas realizadas. Os maiores rendimentos de etanol, em termos absolutos, foram obtidos para CMSXS646 e BRS 511 na colheita de primeiro corte com colmos limpos. A utilização de colmos limpos promoveu, em média, um incremento de 13,5, 14,2, 13,4, 3,3, 7,9, 7,0, 8,0 e 16,4% para etanol, ART, ATR, umidade, ARC, Pol, °Brix, quantidade de caldo, respectivamente, e redução de 17,3% para fibra, em relação às amostras de colmos com folhas. O rendimento médio de etanol por tonelada de caldo extraído foi 28% superior no primeiro corte comparativamente à rebrota.Palavras-chave: Bioenergia, biomassa, °Brix, Sorghum bicolor.  INDUSTRIAL QUALITY AND ETHANOL YIELD OF SWEET SORGHUM GENOTYPES IN MAIN AND RATOON CROPS  ABSTRACT - The yield of sweet sorghum cultivars in first cut and ratoon crops have been studied to enable the cultivation with lower production costs. However, qualitative data on broth quality and yield of ethanol on main crop and ratoon are scarce. The aim of this work was to compare sweet sorghum genotypes regarding the industrial quality and to evaluate the effects of harvests and processed biomass types in the industrial yield for ethanol production. A randomized block design experiment was carried out with three replicates in a split plot design, being the plots composed by 20 sorghum genotypes and the subplots by the types of processed samples or harvests. The highest ethanol yields, in absolute terms, were obtained for CMSXS646 and BRS 511 in first cut with clean stalks. The use of clean stalks promoted, on average, an increase of 13.5, 14.2, 13.4, 3.3, 7.9, 7.0, 8.0 and 16.4% for ethanol, ART, ATR, moisture, ARC, Pol, ° Brix, juice amount, respectively, and reduction of 17.3% for fiber, in relation to samples with stalks and leafs. The average yield of ethanol per extracted juice ton was 28% higher in first cut compared to ratoon.Keywords: bioenergy, biomass, °Brix, Sorghum bicolor.

Sweet sorghum is currently an important alternative for ethanol production in sugar cane off-season. In this study was to evaluate the effects of plant arrangements and the application of atrazine and S-metolachlor on growth and productivity of sweet sorghum. An experiment was conducted in randomized block design and, arranged in split plots with four repetitions. Plots consisted of spacing (0.25 m, 0.45 m 0.45-0.45-0.90 m) and sub-plots of weed control methods - atrazine (2000 g ha-1), atrazine + S-metolachlor (2000 + 720 g ha-1), atrazine + S-metolachlor (2000 + 960 g ha-1), atrazine + S-metolachlor (2000 + 1200 g ha-1), atrazine + S-metolachlor (2000 + 1440 g ha-1). Besides that, manual hoeing control was added. The intoxication of sorghum plants and weed control was evaluated at 7, 14 e 28 days after herbicides application (DAA). Plant height, stem diameter, total fresh matter, juice mass and total soluble solids (°Brix) were evaluated at 120 days after crop emergence (DAE).  There was no interaction between the factors spacings and control method for variables total matter fresh (TMF), height (H), stem diameter (D), juice mass (JM), and Brix. Application of the mixture (atrazine + S-metolachlor) in the highest doses reduced total fresh matter and °Brix. The spacing of 0.25 m provided the highest productivity of fresh matter, juice mass and increased the °Brix. The application of mixture (atrazine + S-metolachlor) controlled 90% of the weeds at 28 days after application. The increasing in doses of S-metolachlor elevates the intoxication in sorghum plants. The mixture (atrazine + S-metolachlor) has a potential for use in weed control in sweet sorghum, but at doses below 960 g ha-1 of S-metolachlor. metolachlor.

Despite the expansion of viticulture in Brazil, the lack of chilling hours is a factor that requires the use of growth inducers to promote sprouting. Erger™ is a product of low toxicity and efficient in the bud induction of apple. However, there is a lack of studies testing such a product on the grapevine. This research was carried out to evaluate the sprouting and phenological cycle of ‘Fiano’ grapevine after Erger™ and calcium nitrate application in comparison to hydrogen cyanamide, as well as characterizing its production in Brazil. The experiment was carried out in Campo Largo, PR, under a trellis system, with plants spaced at 1.25 × 2.7 meters. The experimental design was a randomized complete block design with four replications and three plants per plot. Different concentrations of Erger™ and calcium nitrate (3%, 5%, 7%, and control) were tested compared to the standard dose of Dormex™ (4%) to induce sprouting in ‘Fiano’ grapevine, while phenological aspects of this cultivar were evaluated following the BBCH scale. Soluble solids content, titratable acidity, and pH were evaluated weekly after the beginning of berry maturation. The main biometric and qualitative characteristics of bunches were evaluated at harvest. All treatments presented satisfactory sprouting rates in 2014, but a lower cold accumulation was observed in 2015, and Erger™ application significantly increased sprouting when compared to the control. Plants treated with Erger™ had a delay in sprouting in the two years of study, requiring more time to reach a satisfactory percentage of open buds. The anticipation of sprouting was also observed in all treatments in the second agricultural season due to higher temperatures in relation to the previous year when the occurrence of low temperatures led to a longer time to start bud opening, which was related to ecodormancy. The cultivar Fiano is productive and adapted to the conditions of Campo Largo, PR, Brazil.

AbstractTomato is worldwide the most grown vegetable. The primary target of breeding programs is to develop new tomato cultivars that are resistant to pests and diseases, in combination with high quality and yield, well-adaptation and good firmness. Among the different tomato types, cherry and cocktail tomatoes are widely preferred by consumers due to their better taste and appearance. In this study, two female tester lines were crossed with four male lines to obtain new tomato hybrids. The eight F1 hybrids and two commercial hybrids were planted in a randomised complete block design with two replications in a greenhouse in Antalya. The tomatoes of the hybrids and lines were harvested at fully ripened stage to evaluate yield, total soluble solids (TSS), fruit firmness, lycopene content and fruit colour parameters. TSS values of the cultivars and lines ranged from 4.5 to 9.5 °Bx, fruit firmness from 7.94 to 11.85 kg cm−2, lycopene from 52.10 to 55.88 mg kg−1, yield from 554.3 to 1336.7 g/plant. Hybrid AK0020 was found the best for both yield and quality.
