RESUMO - ACCUMULATION AND DISTRIBUTION OF NUTRIENTS IN FORAGE SORGHUM GENOTYPES UNDER SALINITYABSTRACT -The absorption and distribution control of Na + and Cl-in plant tissues is related directly to the plant tolerance degree to the salinity and can minimize possible nutritional disorders because of these ions competition with elements such as N, P, K, Ca, Mg and S. The aim of this study was to evaluate the salinity effect on the accumulation and distribution of Na, Cl and macronutrients in ten genotypes of sorghum. The experiment was conducted in a greenhouse located at Embrapa Semiarid, in Petrolina, Pernambuco, Brazil. We used a experimental randomized block design in a factorial 10x6 considering ten cultivars of forage sorghum, six levels of salinity and three replications. After harvest, plants were separated into leaves, culms and roots, left to dry and milled for subsequent determination of the elements N, P, K, Ca, Mg, S, Na and Cl. Concomitantly with the salinity increase, it was observed a reduction in the amount of nutrients accumulated in leaves, culms and roots of forage sorghum, directly related to the dry matter losses and competitive effect of Na + and Cl-, which are in excess in the soil solution.

“…This crop stands out as a good forage for the Brazilian semiarid region for being typical of hot climate, with xerophytic characteristics, low demand in soil fertility, easy cultivation and fast establishment and growth, besides a good nutritional value and high forage production (Botelho et al, 2010;Gomes et al, 2006;Santos et al, 2013).…”

A B S T R A C TThis study aimed to evaluate the cultivation of forage sorghum subjected to different leaching fractions with saline effluent from fish-farming under semiarid conditions. The experiment was set in a randomized block design, with four blocks, in split plots, composed of four leaching fractions (0; 5; 10 and 15%) and three forage sorghum varieties ('Volumax' , 'F305' and 'Sudão'). Irrigation was performed using saline effluent from fish farming with electrical conductivity of 2.5 dS m -1 . The analyzed variables were: plant height; stem diameter; width, length and number of leaves; fresh and dry matter yield, and relative contents of potassium and sodium in the shoots. Forage sorghum under saline effluent irrigation and leaching fraction of 15% shows a yield increase of 25%, in comparison to sorghum without the leaching fraction. The variety 'Volumax' was more sensitive to salinity than the others, since it showed lower shoot growth and low values of leaf area, fresh matter and dry matter.Cultivo de variedades de sorgo forrageiro irrigado com efluente salino da piscicultura em condições semiáridas R E S U M O O presente trabalho objetivou avaliar o cultivo de variedades de sorgo forrageiro submetido a diferentes frações de lixiviação com efluente salino da piscicultura em condições semiáridas. Foi adotado o delineamento experimental em blocos ao acaso, com quatro blocos, em parcelas subdivididas compostas por quatro frações de lixiviação (0; 5; 10 e 15%) nas parcelas e três variedades de sorgo forrageiro (Volumax, F305 e Sudão) nas subparcelas. A irrigação foi realizada com efluente salino da piscicultura (CE de 2,5 dS m -1 ). As variáveis avaliadas foram altura da planta; diâmetro do colmo; largura, comprimento e número de folhas; produtividade de massa fresca e seca, além de teores de sódio e potássio na parte aérea. Observou-se que o sorgo forrageiro irrigado com efluente salino, com fração de lixiviação de 15% apresentou um aumento percentual de até 25% na produtividade quando comparada à do sorgo sem fração de lixiviação. A variedade Volumax mostrou-se mais sensível à salinidade que as demais em virtude de apresentar o menor crescimento da parte aérea e baixos valores de área foliar e matéria fresca e seca.

“…(ZHANG et al, 2016). It therefore has greater potential than that of other sorghum cultivars (SANTOS et al, 2013;VON PINHO et al, 2006). However, the use of sweet sorghum in silage production may promote ethanol production inside the silo, since its high non-structural carbohydrate content provides an ideal environment for yeast activity, which converts WSC to ethanol in anaerobic environment (CAVALI et al, 2010).…”

Sorghum stands out among other plants recommended for ensiling due to its forage composition, its resistance to drought, and its planting range. New cultivars of grain and sweet sorghum that can be used for silage production are available, but there is little information regarding their ensiling characteristics. The aim of this study was to evaluate the fermentation characteristics at the ensiling of different purpose sorghum cultivars, at two crop periods. The trial was carried out at the Plant Production Department of the Federal Institute of Education, Science and Technology of Rondônia, Colorado do Oeste campus, Rondônia, Brazil, and chemical analyses were performed at the Laboratory of Animal Nutrition, at the Federal University of Mato Grosso, Cuiabá campus, Mato Grosso, Brazil. The experimental design used was a randomized block, in split-plot design, with four replicates. The plot treatments consisted of six sorghum cultivars grown for different purposes (grain sorghum: BRS 308 and BRS 310; forage sorghum: BR 655 and BRS 610; sweet sorghum: BRS 506 and CMSXS 647). Split-plot treatments consisted of two cropping seasons (first crop and second crop). The grain sorghum cultivar BRS 310 was the only one that had suitable dry matter content for ensiling; however, it was also the only one that did not show ideal water soluble carbohydrate content for ensiling. Nevertheless, all treatments presented pH below than 4.2 and ammonia nitrogen lower than 12% of total N, which indicates that the fermentation inside the silo had proceeded well. For sweet sorghum cultivars, higher ethanol and butyric acid content were observed for the first crop than for the second crop. All evaluated sorghum cultivars can be used for silage production, but the use of sweet sorghum is recommended at the second crop. Key words: Alcoholic fermentation. Fermentability coefficient.
