Item Analisando a contribuição de estratégias agrometeorológicas na produção de espécies forrageiras sob agricultura biossalina por meio de campo e laboratório(2018) Assís, Méry Cristina de Sá; Silva, Thieres George Freire da; http://lattes.cnpq.br/0213450385240546; http://lattes.cnpq.br/6998116555134928Item Eficiência do uso da água e nutrientes da palma forrageira sob diferentes regimes hídricos e sistemas de plantio(2018) Assís, Méry Cristina de Sá; Silva, Thieres George Freire da; http://lattes.cnpq.br/0213450385240546; http://lattes.cnpq.br/6998116555134928Forage cactus is a crop widely used in Brazilian semi-arid region animal production systems, since it presents great adaptation to this region. Thus, the objective of this work was to analyze water efficiency and nutrient use of forage cactus submitted to different water regimes and planting systems. The experiment was carried out in Serra Talhada - PE, from 11/2014 to 11/2015, with "Orelha de Elefante Mexicana" clone forage cactus and cv. SF-15 forage sorghum distributed in randomized blocks, with 4 replications, in a 5x4 factorial arrangement, with five water blades (0%, 25%, 50%, 75% and 100% of reference evapotranspiration - ETo) and four planting systems (exclusive forage cactus, exclusive sorghum, forage cactus-sorghum consortium and palm with cover. The crops productivity was obtained at harvest time and then, efficiency indicators of water use were calculated relating crop productivity in water blade systems, and nutrient use efficiency, relating nutrient productivity to water blades. There was no interaction between water slide and water and nutrient efficiency planting systems use for N, P, K, B, Mn, Zn and Na, however it was observed that higher efficiency of water use at water blades occurred in dry or irrigated condition based on ETo 25% and between the systems, exclusive forage cactus has lower efficiency. In relation to nutrients when influenced by slides under lowest water conditions (dryland and ETo 25%) highest efficiencies are obtained, and when it comes to planting system exclusive forage cactus has the lowest efficiency. There was interaction between water blade and planting system for nutrient utilization Ca, Mg, S, Cu and Fe, being observed a greater influence of the planting system than of water blade system. Considering the water use efficiently based on dry matter, even when there was no interaction between planting systems and water blades, forage cactus planting, forage cactus intercropped with sorghum and forage cactus with cover systems are more efficient than exclusive forage cactus since forage cactus should not be fed to animals as an exclusive diet, the forage cactus-sorghum consortium becomes an efficient alternative to overcome this limitation. The application of 208.3 mm of complementary water distributed regularly during greatest deficit period promotes an increase in forage cactus green matter yield and green and dry sorghum matter. It is indicated its use mainly in forage cactus- sorghum system, since the sorghum has less water use efficiency. Mulching use, consortium with sorghum, as well as complementary irrigation with 208.3 mm in forage cactus cultivation Opuntia stricta (Haw.) Haw., are efficient strategies to promote forage production improvements. The Mulching use promotes greater extraction of nutrients by forage cactus, as well as promotes increased productivity.Item Refinando a avaliação bioclimática do estado de Pernambuco para a criação de vacas leiteiras(2021) Oliveira, Gabriela Mayara Pereira; Silva, Thieres George Freire da; http://lattes.cnpq.br/0213450385240546; http://lattes.cnpq.br/6833841784894704The Brazilian Northeast has shown significant growth in dairy cattle, which has contributed to the improvement of the economy. In this context, the objective was to improve the bioclimatic assessment of the state of Pernambuco for the creation of dairy cows through the application of bioclimatic risk, and multivariate statistics. Meteorological data from 13 to 20 years from 14 municipalities in the state of Pernambuco were used. From the meteorological data, bioclimatic indices were generated, such as ITU, DPL, RCA, TGN, ITGU, and CTR, as well as the bioclimatic risks for levels 10, 15, 20, 25, 30, and 35 kg of animal milk-1 day-1 . A principal component analysis was carried out with bioclimatic indices and animal performance to verify the capacity and the discriminative relationship of the variables in each season of the year. The four principal components were responsible for explaining 85.70% (summer), 88.75% (autumn), 93.06% (winter), and 85.70 (spring) of the total variation of the data sets. The municipalities of Arcoverde and Caruaru were the only ones that showed a negative correlation with the indices of DPL, RCA, CTR, TGN, ITGU, and bioclimatic risk, which qualify as places of significant potential for the implantation of a dairy in the state of Pernambuco
