-This study evaluated the effect of different cutting intensities and years of harvesting on the morphological characteristics and production of fresh (FMP) and dry matter (DMP) of cactus pear cv. Gigante (Opuntia ficus-indica Mill) under conditions of irrigation, high planting density and fertilization, with 12 months of regrowth. The experimental was completely randomized in a factorial design (3 × 2) with 12 replicates. The treatments were three cutting intensities (preserving the mother cladode (PMC), primary cladodes (PPC), or secondary cladodes (PSC)), and two years of harvesting. The soil was classified as Cambisol Haplicum and the irrigation water was classified as C4S1 (EC 5.25 dS.m -1 ) density of 50,000 plants ha -1 . The research evaluated plant height, number of cladodes per plant (NCP), length, width, perimeter and thickness of the cladodes, cladode area (CA), cladode area index (CAI), FMP and DMP. There was no significant interaction between treatments (P > 0.05) for the variables plant height, NCP, CAI and FMP. The variables related to cladode morphology showed a significant interaction (P < 0.05). The treatment PSC resulted in a greater DMP (P < 0.05) with a mean of 27.17 Mg ha -1 yr -1 , compared to PPC (18.58 Mg ha -1 yr -1 ) or PMC (11.78 Mg ha -1 yr -1 ). The treatment PSC promoted greater NCP and forage productivity at harvest and can be considered as a management practice for the sustainability of cactus pear cv. Gigante under irrigation. The more important morphological characteristics were also influenced by the lower cutting intensities.

“…Neste estudo foi avaliada a superação da dormência em sementes das espécies: Angico (A. colubrina), Jurema-branca (P. (Alvares et al, 2013;Pereira et al, 2015). A temperatura e a umidade atmosférica, durante as duas épocas distintas, foram monitoradas através de uma estação meteorológica automática, localizada a cerca de 300 m da área experimental e pertencente ao Instituto Nacional de Meteorologia-INMET (INMET, 2017).…”

A B S T R A C TSome species of the Caatinga present seeds with dormancy, a mechanism that allows germination when the environmental conditions permit its establishment and survival; this feature is advantageous for the perpetuation and undesirable for producers that need a fast production of these plants. The study aimed to evaluate the efficiency of the application of pre-germination treatments in Angico (Anadenanthera colubrina) (Vell.) Brenan, Jurema-branca (Piptadenia stipulacea Benth.) Ducke and Mulungu (Erythrina velutina Willd.). Two independent experiments were carried out at the Serra Talhada Academic Unit using Angico, Jurema-branca and Mulungu seeds, arranged in a completely randomized design, with four replicates and 15 seeds. The seeds were submitted to pre-germination treatments: T1-control, T2-mechanical scarification on the opposite end of the thread with wood sandpaper, T3-mechanical scarification on the opposite end of the thread with wood sandpaper + immersion in water at room temperature for 24 hours and T4-heat treatment with Immersion in water at 80°C for 2 minutes. The parameters evaluated the efficiency: germination percentage and rate of emergence (IVE), biometric data (30 days after sowing), as seedling height, the number of leaves and stem diameter. The seeds of Jurema-branca (P. stipulacea) and Mulungu (E. velutina), submitted to the pre-germinative treatments T2 and T3, showed better germinative performance, reflected in the growth of the seedling. The Angico (A. colubrina) was not sensitive to the application of the treatments, and its germination was nullified for the T3 treatment application. In all cases, variations of the parameters were observed because of the atmospheric conditions.

“…The Northeastern region of Brazil presents a large space-time variation in the climate and in the weather, in intra and interannual scale, being 56.46% of its territory represented by the semiarid region . The Brazilian semiarid region (BSA) is characterized by large periods of water scarcity, mainly due to irregularity and poor rainfall distribution (i.e., 350 to 800 mm year -1 ), with potential evapotranspiration (ETp) values of up to 2,000 mm year -1 , with a wide variation in the air temperature (20.1 to 32.9 ºC) and relative humidity of 60% Pereira et al, 2015). According to Alves et al (2014a) and Carneiro et al (2014), these conditions are related to the high incidence of solar radiation in this region, also affecting soil temperature and evapotranspiration, affecting plant growth and development.…”

“…Forage cactus is a xerophyte species that due to its morphological and physiological characteristics it presents significant tolerance to environments with extended periods of drought. Even with these characteristics, studies have shown the successful performance of this cactus in response to the use of irrigation, with which it is possible to improve the development and productivity of this cultivation (Almeida et al, 2011;Pereira et al, 2015;Queiroz et al, 2016;Silva et al, 2017a).…”

The Brazilian semi-arid is an area that has a strong influence on climatic factors and agricultural vulnerability, which govern the availability and supply of fodder. The understanding of the limitations and the alternatives to be adopted, aid in the improvement of the systems of production of fodder and an increase in the benefits of the system. In this review, we sought to address agrometeorological aspects and agronomic techniques aimed at improving resilience in forage cactus production systems under different cropping systems in arid and semi-arid environments through information on the stability of the plant population contributing to reducing the risk environmental degradation and production losses.
