(2019-07-17) Nascimento, Simone Andrea dos Santos; Almeida, Rosa Honorato de; http://lattes.cnpq.br/4319299572657528; http://lattes.cnpq.br/3647378652257643
Soy, being a very important oilseed for the production of oils and bran, becomes an alternative for the composition of human and animal food, since it has gained great expressiveness in Brazil over the years. Due to the scarcity of studies on soybeans in some Northeastern states and the adequate production arrangements for the crop, it is of great importance to develop research on seeding density, a determining factor in the production environment influencing the growth and development of soybeans, with the objective of evaluating the behavior of the BRS 7780 IPRO soybean variety in different plant densities (333, 416 and 476 thousand plants ha1), in semi-arid conditions, in the municipality of Serra Talhada. The study was developed in the period from March to June 2019, at the Universidade Federal Rural de Pernambuco, Unidade Acadêmica de Serra Talhada. The experimental design used was that of randomized blocks, with three treatments representing planting densities of 333 thousand, 416 thousand and 476 thousand ha-1 plants, with eight repetitions. Plant height and first pod insertion, number of pods and grains per plant, number of branches, wet and dry weight of pods, mass of 1000 grains and estimated grain productivity were evaluated. It was concluded that the height of the plants and the insertion of the first pod are higher with the increase of the seeding density, however, it promoted a greater reduction in the number of branches per plant, number of pods and grains per plant. For the cultivar studied, sowing density extremes did not promote considerable variations in productivity and the weight of 1000 grains. The BRS 7780 IPRO soybean cultivar presented a first pod insertion height close to that adequate for mechanized harvesting
Efeitos combinados da salinidade e do fungo (Trichoderma harzianum) no crescimento do pepino (Cucumis sativus L.)
(2019-07-19) Silva Filho, Renato Veríssimo da; Almeida, Rosa Honorato de; http://lattes.cnpq.br/4319299572657528; http://lattes.cnpq.br/8752721745418531
In Brazil, cucumber is well accepted in all Brazilian regions, including the Northeast Region. In this region, due to the semi-arid condition, it is common for low rainfall to occur, which together with the nature of the source material, generate abundance of saline soils and, consequently, water containing high levels of salts. This salinity compromises the production of cucumbers due to osmotic and ionic effects, which result in changes in the processes of water absorption, transport, assimilation and distribution of nutrients in the plant. Faced with this problem, techniques capable of improving the tolerance of plants with greater sensitivity to salinity have been sought. Among these, biological techniques such as the use of biostimulants have been gaining importance, due to their ability to stimulate the root development of plants and to alter the pH of the rhizosphere, thus reducing the deleterious effect of salinity on this crop. In this sense, the objective of the present study was to analyze the combined effects of salinity and the fungus Trichorderma harzianum on the growth and development of cucumber. The experiment was conducted at UFRPE/UAST, in Serra Talhada/PE, in a randomized block design with five salinity levels (TESTEMUNHA/T0: 0.02; T1: 1.2; T2: 1.4; T3: 2.0; T4: 2.4 dS m-1) with application of a commercial product based on Trichorderma harzianum, at 15 and 30 days after the beginning of salt application. The following were evaluated: number of leaves, leaf area, length of the main stem, number of flowers, number, diameter and length of the fruit, as well as root characteristics such as volume, surface area, length, dry and wet mass of the roots. The data allow us to infer that there is an influence of salinity in the cucumber culture. The biometric variables were directly influenced by the interaction of salinity and fungus, so that the plants treated when associated with the fungus T. harzianum revealed positive responses to salinity.

One of the bottlenecks seen by ornamental sunflower producers in the semi-arid region of the Northeast are edaphoclimatic factors, such as temperature and excessive light, in addition to practical crops, such as soil cover, making it necessary to carry out alternatives that mitigate this stress caused on the plant. Thus, an experiment was conducted in an experimental area at the Federal Rural University of Pernambuco, at the Serra Talhada UFRPE / UAST Academic Unit, from November 2019 to January 2020. With this work, the effects of using of different levels of shading combined with regulator of different dose levels in the growth, development and production of flowers in the sunflower culture. The experimental design used was completely randomized in a 4x4 factorial scheme, with treatments referring to the four levels of growth regulator doses 0; 2; 4 and 6 mg / L-1 in interaction with four shading 0, 30, 50 and 70% for flower production in sunflower culture. Three repetitions were used, with two replicates for each repetition, where the sunflower was evaluated. The treatments started to be applied 15 days after seedling emergence (DAE) and another 15 days when the plant had 6 true leaves. Due to flowering, the phytomass, fresh and dry plant variables, number of leaves, buds and flowers, and plant height were evaluated. In relation to plant height for commercialization, the control showed a better performance. Shading at 30% showed increases in fresh and dry phytomass. For the number of leaves, the highlight was the 70% shaded plants.

Research related to the identification of invasive plants is so far unknown for the culture of cactus in the semi-arid northeast. Therefore, the present study aimed to evaluate the weed community under different cultivation conditions through a phytosociological survey. The experiment was carried out in an experimental area located at the Universidade Federal Rural de Pernambuco, which has been cultivated with forage cactus (Orelha de Elefante Mexicana) and vip ferocious hybrid son, distributed in six treatments: exclusive cactus with and without mulch; palm intercropped with corn with and without mulch; and the condition of exclusive corn with and without mulch. Based on the data obtained, the following phytosociological parameters were calculated: frequency; relative frequency; density; relative density; abundance; relative abundance; and the importance value index. There was a need for greater attention in the area for the management of the poaia-rasteira (Richardia grandiflora (Cham. & Schltdl.) Steud.), which obtained the highest frequencies and importance value index in most conditions of cultivation

(2020) Silva, Michelle Ferreira; Almeida, Rosa Honorato de; http://lattes.cnpq.br/4319299572657528; http://lattes.cnpq.br/8539218987631657
Soy (Glycine max L.) is one of the most important agricultural crops in Brazil, occupying the second largest place in production in the world. 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.

(2022-05-24) Oliveira, Jéssica Patrícia de; Almeida, Rosa Honorato de; http://lattes.cnpq.br/4319299572657528; http://lattes.cnpq.br/4377561093655050
Agroecological Fairs have an indispensable role in safe and healthy food as they provide the supply of different types of products for consumers while guaranteeing the family income of several farmers. The present study aimed to identify the profile of consumers of agroecological products in the city of Triunfo-PE, as well as their satisfaction with the products sold. Data collection was carried out using forms available at the Feira da Agricultura Familiar de Triunfo. The data obtained were tabulated and processed in a Microsoft Excel 2010 spreadsheet. Through the results, the consumer profile was identified and, based on the Net Promoter Score (NPS) methodology, the consumer satisfaction and preference index. Through this study it was possible to identify the profile of people who usually attend the fair, which is mostly composed of women and young people. Through the NPS it was identified that the fair is located in the improvement zone, an area close to the quality one, which indicates a good performance of the agroecological fair in the city. With the application of a form containing open questions, information was collected, which are of paramount importance for the development of possible improvement plans for the fair. Such results proved to be effective in identifying positive and negative points and, therefore, actions that can increase consumer satisfaction, as well as their quantity, are appropriate.

Family agriculture in Brazil accounts for 70% of all food consumed in the domestic market, however, the difficulty of access to information and the lack of technical assistance has promoted the excessive use of pesticides. In Pernambuco, there are about 6,619 tons of pesticides used annually and an average of 1545 cases of intoxication between 2002 and 2014. In view of the above, the objective of the present study was to conduct a survey of the profile of riverine family producers regarding the use of agrochemicals and safety procedures during their use. The study was carried out in the Sertão do Alto Pajeú region of Pernambuco, in the municipality of Calumbi, with family farmers located on the banks of the Pajeú River. The data were collected from the application of an oral questionnaire, subdivided into three themes: 1- Cultures worked; 2- Agrotoxic used and 3- Personal protective equipment. A total of 25 family farmers were interviewed and the choice of farmers was made according to the best profile of family farmer and proximity to the banks of the Pajeú River. This study reveals an important social and environmental problem, which is reproduced in several rural areas of the country, within the context of food production by family agriculture. A significant portion of the farmers interviewed were found to use agrochemicals, which are not recommended for crops and classified as very dangerous to the environment, also highlighting the non-use of IPEs. If these family farmers had the opportunity and technical guidance, access to information and government incentives, the reality presented in this research could be different.
