    Crescimento e produtividade de genótipos de palma, cultivados em diferentes regimes hídricos no semiárido

    Cactus pear is one of the most cultivated species and an important alternative to support food for livestock in the semi-arid region of the Brazilian Northeast, however, some locations do not have a suitable climate for its development, requiring water supplementation. Its productivity and development has better result in the criterion of irrigation management. Thus, the objective of this study is to evaluate the growth and development of cactus pear, using the irrigation management strategy on productivity in different water regimes. The experiment was carried out in a rural property in the municipality of Canindé de São Francisco-SE. The trial was carried out in randomized blocks with 4 repetitions in a 4x2 factorial scheme, with four varieties of palms in two water regimes. The irrigation system used was located with dripped tapes. The agronomic variables studied were: plant height and width, number of paddles per plant, length, width and thickness of the paddle, green mass weight and dry mass weight. To evaluate the production cost in the second cycle of the plant's culture, the effective operating cost (EOC), cost with administrative charge (CEA) and the total operating cost (TOC) were evaluated. The small variety responded positively to the application of irrigation. The varieties: elephant ear, Mexican, girl's hand and giant. There was no increase in the number of rackets with the application of irrigation. The acquisition of mineral fertilizers is the factor that most burdens the total operating cost.

    Produtividade e crescimento de genótipos de palma forrageira irrigados com água salobra
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2022-03-04) Farias, Mayara França; Silva, Jose Madson da; http://lattes.cnpq.br/5749870599305506; Silva, Randerson Cavalcante; http://lattes.cnpq.br/7477067848979919; Gouveia Neto, Gilberto da Cruz
    Forage cactus constitutes an important alternative for forage support for the semiarid Northeastern region of Brazil. Accordingly, a worthy mentioning technology to increase its productivity is the suplementar irrigation. This academic work aimed to study the growing and production features of carmine mealybug resistant cactus genotypes, subjected to varying depths of brackish water suplementar irrigation. Experiments procedures were conducted using water collected from the Poço Doce ́s site, located in the minicipality of Piranhas. In terms of methodology, the tests were carried out on a randomized blocks basis with 4 replications in the split-plot scheme, with the plot consisting of five saline water replacement depths: L1 = 0 mm/month, 7.5 mm/month, 15 mm/month, 22, 5 mm/month and 30 mm/month. These aforementioned replacement depths were divided into three monthly applications, and the subportion was composed of the two varieties of forage cactus (Orelha de Elefante Mexicana and Miúda). Using drip tapes to situate the irrigation system, the following characteristics were evaluated: final plants quantity (plants/m2); number of rackets per plant; height and width of plants (m); primary, secondary and tertiary rackets length (cm), width (cm), thickness (mm), and green mass (kg/racket); dry matter percentage and productivity (Mg/ha). We found that optimal forage cactus growth and productivity were achieved for irrigation depth of 15 mm/month. Last, but not least, we concluded that the Orelha de Elefante Mexicana variety showed better growth and productivity characteristics than the Miúda one, and in addition, it presented small percentages of dry matter regardless of the amount of irrigation.
