1. Effects of different legume green manures on tropical soil microbiology after corn harvest
ABSTRACT Legume green manure is a popular practice for sustainable agriculture in tropical environments. The use of grain, forage and purely green manure legumes in a subhumid tropical area in Northeast Brazil was investigated to determine the total C and N contents and estimate C-microbial biomass, soil basal respiration, microbial and metabolic quotients,

2. Deposition and decomposition of litter in periods of grazing and rest of a tropical pasture under rotational grazing
RESUMO: Os objetivos deste estudo foram determinar taxas de deposição e decomposição de serapilheira em pastagens de Marandu (Urochloa brizantha cv. Marandu) sob a) três formas de suprimento de nitrogênio (N), b) em diferentes estágios de pastejo rotativo e c) comparar a constante de decomposição (‘k’) derivada de “litterbags” com os valore

3. Intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate
Abstract Legume silage can increase the forage quality of the diets as well as supply it with nitrogen, calcium and phosphorus. The objective was to evaluate the intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate. Twelve crossbred sheep with an average initial body weig

4. Food quantity and quality of cassava affected by leguminous residues and inorganic nitrogen application in a soil of low natural fertility of the humid tropics
ABSTRACT The aim of this study was to test the hypothesis that the quality and quantity of biofortified cassava root in a humid tropical environment can be modified with the application of a combination of low- and high-quality residues of leguminous tree species. The experiment was designed as a 6 × 2 factorial (a combination of 4 legume species versus 2 l

5. Whisker-mediated transformation of peanut with chitinase gene enhances resistance to leaf spot disease
Abstract Peanut (Arachis hypogaea) is an important legume and oilseed crop, native to South America and grown in all tropical and temperate regions of the world. A simplified and rapid direct gene delivery system in peanut was developed by vortexing silicon carbide whiskers with callus and with plasmid harboring chitinase and hygromcin genes. The effects of

6. Xaraés palisadegrass remains productive after the disappearance of stylo in tropical legume-grass pasture
Gradual reduction of legumes in mixed tropical pastures requires periodic oversowing. Exploiting the carrying capacity of grass for an extra year after the disappearance of legumes can be economically advantageous to the farmer. This study aimed to evaluate the productivity of Xaraés palisadegrass (Brachiaria brizantha) pastures in response to its historica

7. Estudo morfológico de frutos, sementes e embriões na tribo tropical Dipterygeae (Leguminosae-Papilionoideae)
O presente trabalho analisa e descreve a morfologia de frutos, sementes e embriões de 12 espécies de Dipterygeae. O fruto é consideravelmente distinto entre os gêneros, sendo um legume em Taralea, um legume drupoide em Dipteryx e uma criptossâmara em Pterodon. Foi observado que os três gêneros apresentam características morfológicas distintas no epi

8. Classes of secondary metabolites identified in three legume species
The objective of this study was to identify secondary metabolite classes of tropical kudzu, perennial soybean and archer legumes through identification by phytochemical screening and confirmation by infrared (IR), ¹H and carbon-13 NMR spectroscopy of fractions obtained by organic solvents partition of crude extracts. These analyses allowed for proposing the

9. Detection of 1-aminocyclopropane-1-carboxylate oxidase activity in seeds of Stylosanthes humilis H.B.K
The activity of 1-aminocyclopropane-1-carboxylate oxidase (ACO) was characterized in seeds of the tropical legume Townsville stylo (Stylosanthes humilis) both in vitro (desalted extract of non-dormant seeds) and in vivo (entire dormant seeds). Optimum conditions for maximum in vitro ACO activity in a Trizma-HCl 100 mM buffered medium were: pH 7.0, temperatur

10. Modificações morfológicas e metabólicas em gramínea e leguminosa forrageiras tropicais relativas ao suprimento de enxofre / Metabolic and morphological changes in grass and legume tropical forages related to sulfur supply
O enxofre é um dos elementos essenciais para as plantas e as exigências nutricionais nesse nutriente variam com a espécie e a taxa de crescimento das plantas. Com o objetivo geral de avaliar o efeito da nutrição em enxofre no crescimento e no metabolismo do capimtanzânia (Panicum maximum cv. Tanzânia) e do estilosante (Stylosanthes guianensis cv. Mine

11. Productivity, utilization efficiency and sward targets for mixed pastures of marandugrass, forage peanut and tropical kudzu
This study was carried out to evaluate the productivity and utilization efficiency of a mixed marandugrass (Brachiaria brizantha cv. Marandu), forage peanut (Arachis pintoi cv. Mandobi) and tropical kudzu (Pueraria phaseoloides) pasture, rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight), in order to define

12. Solubilisation of inorganic phosphates by inoculant strains from tropical legumes
Microbial solubilisation of low soluble inorganic phosphates is an important process contributing for the phosphorus available to plants in tropical soils. This study evaluates the ability of inoculant strains for tropical legumes to solubilise inorganic phosphates of low solubility that are found in tropical soils. Seven strains of Leguminosae nodulating ba
