The interference of weeds in the soybean crop can lead to losses that reach 80%, if its management is not adequate, however, the phenological phase of the crop and the period of living with the weed species intensify the interference, which may whether or not the plant shows indications of damage in its development. Based on this, the present work had as general objective to study the interference of weeds on the soybean culture. The experiment was conducted in the field for a period of 35 days, using soybean, var. Tracajá. The design used was randomized blocks, where the treatments consisted of five weed control periods since the emergence of soybean; Witness M (Without weeding); Witness C (with weeding 0-35 days); C7 (weeding 0-07 days); C14 (weeding 0-14 days); C21 (Weeding from 0 to 21 days). Plant height, stem diameter, number of leaves, fresh and dry mass of aerial part and root system and total chlorophyll contents, a and b of soybean were evaluated, in addition to the survey of the main weed species occurring in the cultivation area. The data were subjected to analysis of variance and the means compared by the Tukey test at 5% probability. Twenty vegetable species were registered in the soybean cultivation area, distributed in 14 botanical families, and the weeds considered of greatest importance were Euphorbia heterophylla L (dairy), Cyperus rotundus L. (tiririca), Merrenia aegyptia (L). Urb (jitirana), Amaranthus deflexus L. (caruru), Cenchus echinatus L. (carrapicho grass); and the control periods evaluated did not interfere with soybean development; and in the absence of weed control, there was negative interference on the variables: stem diameter, number of leaves, total chlorophyll, a and b, and dry and fresh biomass of the shoot and root.Item Desenvolvimento inicial do feijão-caupi em função de crescentes doses de molibdênio(2019) Sousa, José Victor Lessa de; Oliveira, Alexandre Campelo de; http://lattes.cnpq.br/8164135937542569; http://lattes.cnpq.br/7406808303559442The cultivation of cowpea began with the advance of colonization of the country, being introduced in the state of Bahia and spread by routes in the interior of the Northeast, becoming highly adapted to edaphoclimatic conditions and characterizing as the main source of protein of the sertanejo until nowadays. Even when it is a legume, the bean can not supply its nitrogen demand only with what is produced by biological fixation, and associated with this condition, the deficiency of molybdenum, an important element in nitrogen metabolism can be an important strategy of nitrogen. nutritional management that provide the expression of their maximum productive potential. The objective of this work was to evaluate the behavior of cowpea cv. Paulistinha, when subjected to increasing doses of molybdenum associated with nitrogen doses, seeking to determine the treatment that provided the best development for the studied variables. The experimental design was in blocks, in a 5x2x3 factorial arrangement, with the following treatments: 5 doses of molybdenum (0, 40, 80, 120 and 160 g / ha), and 2 doses of nitrogen (0, 80 kg / ha). , with 3 repetitions, totaling 30 experimental units. The source of molybdenum used was sodium molybdate, and nitrogen, urea. The treatments were applied 20 days after seedling emergence. The studied variables were: plant height (cm), stem diameter (mm), leaf area (cm²) and fresh matter mass (g). The data were submitted to variance analysis and later to polynomial regression analysis. Increasing doses of molybdenum applied via leaf provided higher plant height, stem diameter and leaf area in cowpea. The variable fresh matter mass was not influenced by the applied treatments.Item Manejo e caracterização de acessos e variedades de videira nas condições do semiárido nordestino(2019) Nunes, Adriana da Silva; Ataíde, Elma Machado; http://lattes.cnpq.br/2422663252620574; http://lattes.cnpq.br/7066574850437767
