Item Respostas agronômicas do feijão caupi (Vigna unguiculata (L.) Walp.) sobre diferentes proporções: solo e esterco suíno em dois sistemas de cultivo(2019-07-17) Jesus, Maria da Saúde Santos de; Simplício, Josimar Bento; http://lattes.cnpq.br/1876691945804390Cowpea is a food crop grown in several Brazilian regions, rich in protein is one of the most important legumes and even in soils of low fertility, regions of high temperatures and conditions of water stress produces well. The area cultivated with cowpea in Brazil for the 2017/2018 harvest was approximately 1,440,000 ha, with the Northeast region having the largest planting area, 404,20 thousand ha. Given its great importance for the Northeast region and considering a crop that presents rapid expansion throughout Brazil, it is also considered as one more option for export culture. The creation of confined animals grows every year and this growth favors a considerable volume of waste that if thrown into the environment, can cause damage to this environment. In this sense, the present research proposed to evaluate in a 2x3x2 factorial scheme the behavior of two Creole varieties of cowpea, LA2017 and CB2017, originating from communities of rural producers in the municipality of Santa Cruz da Baixa Verde - PE, The authors present three proportions of pork soil and manure, in two culture conditions, with and without dead cover, in experimental design of casualized blocks, in the experimental area of the Academic Unit of Serra Talhada (UAST), in the Sertão do Pajeú micro-region. By means of the results observed, it was concluded that LA2017 presented superior behavior in the cultivation system with dead cover of 35% for the weight of pods per plant. While the CB2017 presented more significant performance in the cultivation system without dead cover. The proportion with 100% pig manure increased by up to 27% the weight of seeds when compared to the control, proportion 100% soil. Overall, the presence of manure increased the development of cowpea plants.Item Adubação potássica em clones de palma forrageira(2019) Cirino Júnior, Baltazar; Leite, Maurício Luiz de Mello Vieira; Oliveira, Alexandre Campelo de; http://lattes.cnpq.br/8164135937542569; http://lattes.cnpq.br/4204641633941814; http://lattes.cnpq.br/4245406622322251The objective of this study was to evaluate the agronomic performance of Nopalea cochenillifera clones under different levels of potassium. Cladodes of forage palm were selected and collected (in the middle third of the plant), which was three years old, in the UAST experimental area. These cladodes went through a healing period of 10 days. They were then placed in pots (larger diameter) = 24 cm (smaller diameter) = 17 and 23 cm deep), with a capacity of 7 kg of soil, presenting deep drains, covering the bottom of the vessel with gravel to facilitate drainage. The experiment was arranged in a randomized block design in a 5x2 factorial scheme, using five levels of potassium (0, 250, 500, 750 and 1000 Kg.ha-1) and two forage palm clones (Giant Sweet and Sweet Child), with four replicates. Five biometric campaigns were carried out in August, September, October, November and December / 2018 to measure the plant height, length, width and thickness of cladodium, as well as the number of cladodes in order and totals . For the comparison test of means, only the data of the last campaign were used. The clones presented a similar response to potassium fertilization, presenting non significant results for fertilization levels. When comparing the two clones, there was no significant difference for all studied variables: plant height, number of cladodes, length, width and thickness of cladodes. Potassium fertilization does not influencethe morphological, productive and potassium parameters of plant tissues during the initial growth of the genus Nopalea. The software used was R-project version 3.5.0 and SigmaPlot 10.0.
