“…However according to Silva et al (2015b), cultivar Miúda showed superiority of over 200% in the number of cladodes per plant compared to the cultivars IPASertânia (Baiana) and Orelha Elefante. Cunha et al (2012) reports that lower cladodes are observed in cultivar Miúda. This function is needed to distribute the nutrients to a larger number of cladodes, but their superiority as the number is effectively associated with the morphological characteristics of the genre.…”

“…Consoli et al (2013) . Cunha et al (2012) also in their study of Miúda cultivar reported an average production of 180 t ha -1 in green matter forage cactus at 20 months, with a density of 40,000 plants per ha -1 . Other factors such as greater availability of nutrients in the soil, mineral fertilizers are essential for obtaining high yields are also examined.…”

“…Cunha et al (2012) suggests that the death of the roots of forage cactus at the start of the dry season is a mechanism to save nutrients and water by plants. Therefore, irrigation that ensures the survival and full growth of the roots might explain the high yields achieved.…”

Morphological Characteristics and Forage Productivity of Irrigated Cactus Pear Under Different Cutting Intensities

et al. 2016

-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.

-Cactus is crucial for the livestock of semi-arid regions in Brazil. This plant has shown the high productivity of forage, which is influenced by several management factors. This study aimed to evaluate the effect of organic fertilization doses (20, 40 and 80 t/ ha of bovine manure/ha/two years) and planting densities (20, 40, 80 and 160 thousand plants/ha) on the productivity of cactus pear Clone IPA-20 (Opuntia ficus-indica Mill). At the Experimental Station of Caruaru at the Agronomic Institute of Pernambuco, IPA has conducted the experiment. The experimental design was randomized blocks, with split plot arrangements. Higher shoot productivity was observed with increased population density and the application of manure at 80 t ha-1two years-1 with values of 61, 90, 117 and 139 t DM ha -1 two years -1 at densities of 20, 40, 80 and 160,000 plants ha-1. The planting density influenced the productivity of cladode-plant and root dry weight, showing exponential responses, with higher cladode-plant and roots weight by area observed with increased plant density. The efficiency of organic fertilization decreased with the increase in manure doses. For increase cactus productivity, 40 t of bovine manure ha -1 two years -1 for plantations with 160,000 plants/ha is recommended. , 80 e 160.000 plantas/ha. A produtividade do cladódio-planta e peso seco da raiz foram influenciados pela densidade de plantio, apresentando respostas exponenciais, tendendo a apresentar maior peso do cladódio planta e raízes por área com a elevação da densidade de plantio. A eficiência da adubação orgânica diminuiu com a elevação das doses de esterco. Recomenda-se para plantios com 160.000 plantas/ha aplicação de, no mínimo, 40 t de esterco bovino/ha/dois anos para incremento na produtividade da palma. KeywordsPalavras-chave: Cactácea.
