RESUMO: Estudou-se o comportamento de mudas de maracujá, quando formadas, utilizando como adubo o biofertilizante de origem suína em experimento realizado em abrigo telado, no IFCE, Campus Crato-CE, com delineamento experimental inteiramente casualizado com seis repetições, tendo como tratamento doses de biofertilizantes (0, 10, 25, 50, e 75 m 3 de biofertilizante por ha). Cada unidade experimental constou de 4 plantas úteis onde foram analisados a altura e número de folhas de mudas em diferentes períodos após a semeadura. Conclui-se que no ultimo período de observação, para as doses de 50 e 75 m³ ha-1 , as mudas refletem um maior intervalo de crescimento alcançando alturas acima de 50 cm e número de folhas acima de 16, demostrando claramente que incrementos ainda podem ocorrer se aumentam as doses de biofertilizantes.

Each experimental unit consisted of 4 useful plants where were analyzed the height and number of leaves of seedlings in different periods after the sowing. It is ended observation period, for the levels of 50 and 75 m³ ha-1 , the seedlings reflect a larger growth interval reaching heights above 50 cm and
Soil fertilization using materials of animal origin, such as biofertilizers, is an important practice to maintain productive soil, as they provide beneficial effects on soil's physical, chemical, and biological properties. This study aimed to evaluate the number of fruits, fruit mass, and yield of yellow passion fruits in the first year of cultivation with the application of swine wastewater (SW) treated in a biodigester. The experiment was set up at the experimental area belonging to IFCE Crato, CE, Brazil, with a spacing of 5.0 m between plants and 3.0 m between rows, using the espalier system of training and drip irrigation. The experiment was conducted in a randomized block design, with five treatments and four replications. Treatments consisted of five SW doses (D1 = 0, D2 = 0.50, D3 = 1.00, D4 = 1.50, and D5 = 2.00 L plant−1) applied at two phenological stages of the crop. The results were subjected to analysis of variance at a 5% significance, followed by the regression test. The increased SW doses influenced all the studied variables, following the linear and quadratic regression models, except for the mean fresh fruit mass. The highest yield was achieved with the highest studied dose, being an interesting alternative for recommendation to farmers in the region.
