“…Photosynthesis is a key factor of productivity and growth of forage plants, thus, the remaining cladode area after cutting the forage is directly related to growth. Donato et al (2014) recorded a mean cladode area of 350 cm 2 for 20-month-old cactus pear cv. Gigante under different spacing and organic fertilizer levels, which is a lower value than that in this study, which might be related to the use of irrigation and chemical fertilizers.…”

-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.

“…CV = Coefficient of variation *Significant at 0.05 probability level by t-test; **Significant at 0.01 probability level by t-test manure doses (Table 2; Figure 1E and F). The variation for extraction/exportation of nutrients followed the pattern of dry matter production (Donato et al, 2014), with differences only distance between plants decreases, there is an increment in the competition of roots for more mobile nutrients in the soil, such as N, which is transported preferentially through mass flow. The largest amount of NEE occurred at the spacing of 2.0 x 0.25 m, being 140 kg ha -1 for every 10 Mg ha -1 of dry matter, and the lowest one, 125.6 kg ha -1 , at the spacing of 1.0 x 0.5 m. The NEE showed an increasing linear behavior ( Figure 1A).…”

“…Changes in crop management, such as population density, combination of spacings and doses of organic (Donato et al, 2014) or chemical fertilization can interfere with the use of radiation and nutritional status of the plant (Galizzi et al, 2004;Silva et al, 2012), with consequent increment in the photosynthetic rates, growth and yield (Blanco-Macías et al, 2010), and in the extraction/exportation of nutrients.

A B S T R A C TThis study aimed to evaluate the extraction/exportation of macronutrients by cladodes of 'Gigante' cactos pear, grown under diferente spacings and doses of cattle manure applied to the soil 600 days after planting. Twelve treatments were used, three spacing (1.00 x 0.50; 2.00 x 0.25 and 3.00 x 1.00 x 0.25 m) and four doses of cattle manure (0, 30, 60 and 90 Mg ha -1 year -1 ), arranged in a 3 x 4 factorial scheme in randomized blocks, with three replicates. The extraction/exportation of N, P, K, S, Ca and Mg was determined, whose respective values for maximum dry matter production (21.8 Mg ha -1 ), with a cattle manure dose of 71.8 Mg ha -1 year -1 were: 287.9, 46.2, 924.2, 40.7, 609.7 and 249.1 kg ha -1 , 600 days after planting. The amounts extracted/exported from N, P, K and Ca varied independently with spacings and manure doses, while Mg and S were dependent on the interaction between factors. The doses of manure are insufficient to meet the demand of extracted/exported K, Ca and Mg. The increments in the doses promote greater nutrient uptake by the plant. The extracted/exported macronutrients in largest amounts are: K, Ca, N, Mg, P and S, in this order. Extração/exportação de macronutrientes por cladódios de palma forrageira 'Gigante' sob diferentes espaçamentos e adubação orgânica R E S U M O Objetivou-se, com este trabalho, avaliar a extração/exportação de macronutrientes por cladódios colhidos da palma forrageira 'Gigante' , cultivada sob diferentes espaçamentos e doses de esterco bovino aplicadas ao solo aos 600 dias após o plantio. Foram utilizados 12 tratamentos, três espaçamentos (1,00 x 0,50; 2,00 x 0,25 e 3,00 x 1,00 x 0,25 m) e quatro doses de esterco bovino (0; 30; 60 e 90 Mg ha -1 ano -1 ), dispostos em fatorial 3 x 4 num delineamento em blocos casualizados e três repetições. Determinaram-se a extração/exportação de: N, P, K, S, Ca e Mg cujos respectivos valores para máxima produção de matéria seca (21,8 Mg ha -1 ), com uma dose de esterco de 71,8 Mg ha -1 ano -1 foram: 287,9; 46,2; 924,2; 40,7; 609,7 e 249,1 kg ha -1 , aos 600 dias após plantio. As quantidades extraídas de N, P, K e Ca variaram de forma independente com espaçamentos e doses de esterco enquanto as de Mg e S foram dependentes da interação entre os fatores. As doses de esterco são insuficientes para atender às quantidades extraídas/exportadas de K, Ca e Mg. Os incrementos nas doses promovem maior extração de nutrientes pela planta. Os macronutrientes extraídos/ exportados em maior quantidade são: K, Ca, N, Mg, P e S, nesta ordem.

The objective of this study was to evaluate growth and development in an irrigated forage cactus–sorghum intercropping system under different strategies for improving agricultural resilience. The research was carried out from 2018 to 2020 in Serra Talhada, Pernambuco, Brazil, in four experiments in a randomized block design, each with four replications. The first experiment consisted of different configurations for the cactus–sorghum intercropping system (Orelha de Elefante Mexicana [OEM]‐single crop [SNG], IPA Sertânia [IPA]‐SNG, Miúda [MIU]‐SNG, OEM–SF11, OEM–Progenitor 288 [P.288], OEM–467, IPA–SF11, IPA–P.288, IPA–467, MIU–SF11, MIU–P.288 and MIU–467); in the second and third experiments, the cactus–sorghum system was planted under different planting densities (100,000; 50,000; 33,333; 25,000 and 20,000 plants ha−1 for forage cactus and 200,000 plants ha−1 for sorghum) in east–west and north–south orientations, respectively; and the fourth experiment consisted of different planting densities for the cactus and sorghum (50,000; 40,000; 33,333; and 28,571 plants ha−1 and 200,000; 160,000; 133,333; and 114,285 plants ha−1, respectively). The maximum values of the dry matter accumulation rate were observed in the cultivation configurations that contained the OEM clone and at the highest densities. The different cultivation configurations affected the duration and number of phenophases. The cutting time increases as the planting density increases (50,000 and 100,000 plants ha−1) and when the OEM clone is used.
