Item Influência do uso de biofertilizante a base de esterco caprino (BioCapri) na dinâmica de crescimento e produção de palma forrageira no semiárido brasileiro(2021-02-23) Leite, Renan Matheus Cordeiro; Silva, Thieres George Freire da; http://lattes.cnpq.br/0213450385240546; http://lattes.cnpq.br/9490242836620362Several problems are threatening food security in the world, which is even more worrying in climatically vulnerable locations, requiring the adoption of agricultural resilience practices to mitigate the effects of climate change on the production chain in semiarid regions. The forage cactus becomes a good alternative for the production of forage due to its high adaptation to adverse climatic conditions, in addition to having a low production cost, organic fertilization can provide an increase in the agronomic performance of the crop. Maintaining the supply of food for herds in times of drought. This work investigated the application of sustainable and low-cost techniques to the cultivation of forage cactus in the Brazilian semiarid region, aiming at an efficient management of resources, an increase in productivity and a better understanding of the growth dynamics. Two forage cactus clones were evaluated, Miúda (Nopalea cochenillifera (L.) Salm-Dyck) and Orelha de Elefante Mexicana (Opuntia stricta (Haw.) Haw.), Conducted in pots and subjected to five doses of liquid biofertilizer at based on goat manure (BioCapri), with 0, 50, 100, 150 and 200 mL plant-1 month-1 , and a dose of goat manure (180 cm3 plant-1 ). Monthly biometric assessments were carried out during the experimental period to assess the growth and development of the forage cactus, obtaining plant height and width, number of cladodes and length, width, perimeter and thickness of the cladodes. The productivity of the forage palm was obtained by means of a single biomass (dry mass, DM) event, being carried out at the end of each cycle. In order to establish a phenology of forage cactus, the beginning of a new phase was considered when a production tax of a specified order of cladodes was exceeded by the rate of production of cladodes of the subsequent order. Evaluate the efficiency of the use of radiation and water. It was found that the manure and the doses of applied liquid biofertilizer (0, 50, 100, 150 and 200 mL) did not affect most of the biometric variables analyzed, however, the clone factor differed due to the intrinsic characteristics of the clones, where the OEM clone excelled in variables such as CC, LC, PC, AC and IAF. Although the MIU clone has a lower radiation interception, a better capacity for converting to biomass was observed due to the superior MS content of this clone. The contribution of biofertilizer, as well as the use of goat manure, did not cause results obtained in the forage yield, however the clone differed due to its intrinsic characteristics. The development of future research with forage cactus and its natural resource efficiencies are essential to document, and describe the relationship of this crop with the environmental conditions and soil fertility.Item Caracterização fenológica e qualidade de frutos de umbuzeiro em clima semiárido do estado de Pernambuco(2019-07-10) Dores, Tamires Eduvirgem das; Ataíde, Elma Machado; http://lattes.cnpq.br/2422663252620574; http://lattes.cnpq.br/5487942250380238Umbuzeiro (Spondias tuberosa Arruda Câmara) is a species belonging to the Anacardiaceae family, endemic to the Brazilian semiarid region, and there are no reports of its occurrence in other regions of the planet. The plant has great socio-environmental and economic importance for the Caatinga biome, as it survives very well the hostile conditions of the semiarid climate. However, studies with this fruit are scarce in all areas of research. Notably with regard to its phenological behavior and fruit quality, this study aimed to characterize the phenological stages and fruit quality of umbuzeiro in semiarid climate of the state of Pernambuco. The experiment was carried out with umbuzeiro culture, from November 2017 to April 2018, using three adult accessions, located in the Mata da Pimenteira State Park, Serra Talhada-PE. The physical and physicochemical characterization of the fruits was carried out at the Chemistry Laboratory of the Federal Rural University of Pernambuco of the Serra Talhada Academic Unit. Data were obtained from INMET and evaluated using descriptive statistics, where each value represents the means and standard deviation for the variables studied per plant and the simple correlation between the duration of each phenological stage (in days) and each variable in the period. of the study. To evaluate the umbuzeiro phenology in the 2017/18 agricultural cycle, we evaluated the number of days from flowering to fruiting, followed by the number of days from fruiting to harvest. The curve and rate of fruit growth were also analyzed. For fruit quality assessments the following physical attributes were determined: Diameter (mm), length (mm), shape, mass (g) and fruit yield (%), pulp, rind and stone. For the physicochemical attributes it was determined: the soluble solids content (SS%) and technologist index. Under Pernambuco semi-arid conditions, the average number of days between fruit formation and harvest for the three evaluated accessions was approximately 129.3 days and the average period between floral anthesis and fruit formation was 3.5 days. . The curve representing umbus growth had sigmoidal behavior. Regarding quality attributes, access three presented the highest pulp yield (72.63% ± 2.46%), while access two presented the lowest value (65.56% ± 5%). , 62%). The average soluble solids content for fruits of the three accessions was 14.33%. There is potential for commercialization of fruits from the accesses of umbuzeiros studied in the fresh fruit market. Because it is a fruit tree that can be economically exploited and has a high production potential under semi-arid conditions, it is a great alternative to improve the income of family farmers who produce under rainfed conditions, justifying the need for greater attention to culture. Given this, it is understood that to have commercial exploitation of the culture of umbuzeiro, it is necessary to promote the conduction of more research, capable of generating information that reaches the target population
