Abstract

Water stress can limit the growth and production of cowpea (Vigna unguiculata (L.) Walp.), necessitating the use of strategies that induce plant tolerance to mitigate its effects on the crop. This includes the application of salicylic acid (SA) and antitranspirant polymer (AP). The objective of this study was to evaluate the effect of SA and AP applications on the growth and production of cowpeas subjected to water stress. The experiment was conducted in field conditions at Sítio Boqueirão, Catolé do Rocha, Paraíba, Brazil. The experimental design used was randomized blocks, comprising 10 treatments with four replications. The evaluated treatments included nine combinations generated according to the Central Composite Design experimental matrix, involving five doses of SA and five doses of AP applied to plants under water stress, along with an additional treatment (without water stress and application of SA and AP). The assessed variables included morphological parameters and yield. The data were subjected to canonical correspondence analysis and confidence ellipses. The application of SA and AP increased growth (summer and spring) and productivity (summer). However, in spring, there was a decrease in productivity and an increase in the number of days until the initiation of pod harvesting in cowpeas under water stress. [ABSTRACT FROM AUTHOR]

Abstract

Objetivou-se com este trabalho caracterizar plantas daninhas em área rotacionada de milho e feijão - caupi em sistema de plantio direto. As coletas foram realizadas quatro meses após a colheita do milho. Para amostragem, utilizou-se quadrado de ferro vazado, 0,50 • 0,50 m, lançado aleatoriamente vinte e cinco vezes na área experimental com 1508 m2. As plantas daninhas foram identificadas e quantificadas por meio do somatório das amostras obtidas pelo lançamento do quadrado. As variáveis avaliadas compreenderam: frequência, densidade, abundância, frequência relativa, densidade relativa, abundância relativa e índice de valor de importân cia das espécies. Foram descritas as classes botânicas, famílias, espécies, tipo de propagação, ciclo de vida e hábito de crescimento. Na área experimental foram identificadas 38 espécies, distribuídas em 7 famílias, su a maioria (68,4%) a classe botânica das Dicotiledôneas. Houve predominância das famílias Fabaceae (28,9%) e Poaceae (26,3%). As espécies que apresentaram maior índice de valor de importância, foram: Digitaria horizontalis com 44,66% precedida da Cyperus flavus com 34,13%, Digitaria insulares com 22,87%, Cyperus sp. com 16,18% e Brachiaria plantaginea com IVR de 14,75%, que apresentam importância da mesma ordem de grandeza e devem ser igualmente consideradas na estratégia de manejo The aim of this work was to characterize weeds in a rotational area of maize and cowpea under notillage system. The samples were collected four months after the corn harvest. For sampling, 0.50 • 0.50 m cast iron square, randomly cast twenty-five times in the experimental area with 1508 m2 was used. The weeds were identified and quantified by means of the sum of the samples obtained by the launch of the square. The evaluated variables included: frequency, density, abundance, relative frequency, relative density, relative abundance and importance value index of the species. The botanical classes, families, species, type of propagation, life cycle and habit of growth were described. In the experimental area, 38 species were identified, distributed in 7 families, most of them (68.4%) the botanical class of dicotyledons. The families Fabaceae (28.9%) and Poaceae (26.3%) predominated. The species that presented the highest value of importance were: Digitaria horizontalis with 44.66% preceded by Cyperus flavus with 34.13%, Digitaria insulares with 22.87%, Cyperus sp. with 16.18% and Brachiaria plantaginea with IVR of 14.75%, which are of the same order of magnitude and should also be considered in the management strategy

Abstract

The municipality of Bonfim is the second largest watermelon producer in the state and the incidence of weeds is as one of the factors that most affect the quality and crop productivity. The objective of this work was to study floristically weeds in watermelon crops in the municipality of Bonfim, in Roraimense savannah. The survey was conducted in 10 properties with an area of around 40 ha commercial planting watermelon. To collect the weeds used a square cast iron with dimensions of 0.50 x 0.50 m, being released randomly in the area. They were identified to genus, species, family and botany class. the phytosociological parameters were calculated: frequency, density, abundance, relative frequency, relative density, relative abundance and relative importance value index. There were also evaluated the life cycle, growth habit, propagation method and the photosynthetic pathway of invasive species. The composition of the infesting weed community in the raised area was considered heterogeneous, with 17 species in 10 plant families. Families with higher incidence were Poaceae and Fabaceae. The Digitaria and Sida genres had the highest number of species. Most of the identified weed spreads only by seed have annual life cycle and the C3 photosynthetic pathway., O município de Bonfim é considerado o segundo maior produtor de melancia do Estado e a incidência de plantas daninhas encontra-se como um dos fatores que mais afetam a qualidade e produtividade da cultura. Objetivou-se com este trabalho estudar floristicamente as plantas daninhas em cultivos de melancia no município de Bonfim, na savana Roraimense. A pesquisa foi realizada em 10 propriedades, com uma área em torno de 40 ha de plantio comercial de melancia. Para a coleta das plantas daninhas utilizou-se um quadrado de ferro vazado com dimensão de 0,50 x 0,50 m, sendo lançado aleatoriamente na área. Foram identificadas a nível de gênero, espécie, família e classe botânica. Foram calculados os parâmetros fitossociológicos: frequência, densidade, abundância, frequência relativa, densidade relativa, abundancia relativa e índice de valor de importância relativo. Foram ainda avaliadas o ciclo de vida, hábito de crescimento, método de propagação e a rota fotossintética das espécies invasoras. A composição da comunidade infestante de plantas daninhas na área levantada foi considerada heterogênea, apresentando 17 espécies distribuídas em 10 famílias botânicas. As famílias com maior ocorrência foram as Poaceae e Fabaceae. Os gêneros Digitaria e Sida apresentaram o maior número de espécies. A maioria das plantas daninhas identificadas propaga-se exclusivamente por sementes, apresentam ciclo de vida anual e a rota fotossintética C3.
