Monocrotaline presence in the Crotalaria (Fabaceae) plant genus and its influence on arthropods in agroecosystems

Braz. j. biol; 84 (), 2024
Abstract Crotalaria (Fabaceae) occurs abundantly in tropical and subtropical regions and has about 600 known species. These plants are widely used in agriculture, mainly as cover plants and green manures, in addition to their use in the management of phytonematodes. A striking feature of these species is...

Crotalaria and millet as alternative controls of root-knot nematodes infecting okra

Biosci. j. (Online); 36 (3), 2020
The relationship of crops grown in rotation or in succession has increased every day and the use of antagonistic plants and/or non-host plants is one of the most efficient practices of integrated management of nematodes. This study aimed to evaluate the efficiency of crotalaria (Crotalari...

Germination of Crotalaria and Lupinus (Fabaceae) seeds submitted to different pre-germination treatments and their effect on enzymatic activity during early germination

Braz. j. biol; 80 (1), 2020
Abstract Most of the wild and native legume seeds has a hard and impermeable testa, which causes physical dormancy and prevents them from germinating even when environmental conditions are favorable. The study evaluated the effect of scarification treatments on germination and enzymatic activity of Crot...

Experimental poisoning by Crotalaria lanceolata and Crotalaria pallida seeds in broilers

Pesqui. vet. bras; 39 (11), 2019
Crotalaria lanceolata E. Mey. and Crotalaria pallida Aiton. are leguminous plants of family Fabaceae found in most of the Brazilian territory. They were initially used as green manure and due their easy spread they are currently considered weeds in crops. Soybean and corn contamination can occur through ...

Physical and chemical properties of an oxisol after maize cropping on rotation with leguminous plants

Biosci. j. (Online); 35 (4), 2019
Crop rotation has been a daily management to ensure viability of no-tillage system; however, it is few accepted and practiced by farmers. Thus, this study aims to establish a crop rotation scheme in soil quality. Consequently, cover crops of dwarf mucuna, pigeon pea dwarf, sun he...

Leaf area estimation from linear measurements in different ages of Crotalaria juncea plants

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT The goal of this study was to estimate the leaf area of Crotalaria juncea according to the linear dimensions of leaves from different ages. Two experiments were conducted with C. juncea cultivar IAC-KR1, in the 2014/2015 sowing seasons. At 59, 82, 102, 129 days after sowing (DAS) of the first an...

Extratos de Brunfelsia uniflora na germinação de sementes de Crotalaria spectabilis

As sementes do gênero Crotalaria L., de um modo geral, apresentam dificuldades no processo germinativo. O objetivo da pesquisa foi avaliar a eficiência do extrato bruto de Brunfelsia uniflora na germinação de Crotalaria spectabilis. O delineamento foi inteiramente casualizado, com quatro tratamentos ...

Rendimento de massa de adubos verdes e o impacto na fertilidade do solo em sucessão de cultivos orgânicos

Biosci. j. (Online); 29 (6), 2013
O objetivo deste trabalho foi avaliar a produção de massa, teores e aporte foliares de adubos verdes, utilizados em região de altitude do Espírito Santo, adequados à implantação da prática de plantio direto de hortaliças sob manejo orgânico. Objetivou-se também avaliar a evolução da fertilid...

Adubação verde e alterações nas características químicas de um Cambissolo na região de Ji-Paraná-RO

Acta amaz; 40 (3), 2010
A adubação verde promove benefícios nas características químicas, físicas e biológicas do solo. O trabalho avaliou o efeito da incorporação de diferentes adubos verdes nas características químicas de um Cambissolo háplico eutrófico. Foi utilizado o delineamento em blocos ao acaso, com oito t...
