“…Isso ocorre devido ao porte dessa variedade que apresenta cladódios pequenos, porém em grandes quantidades, reduzindo a concentração de água e, consequentemente, aumentando o teor de massa seca (Figura 7). A variedade Orelha de elefante mexicana apresentou a menor produção, com 133,3 g planta -1 de MS, fato explicado por Santos et al (2006), que ao trabalharem com clones de palma forrageira, observaram que a variedade Miúda, do gênero Nopalea, apesar de possuir menor produção de massa fresca, comumente possui teores médios de massa seca superiores aos clones do gênero Opuntia. Esses valores foram bem superiores aos encontrados por Dubeux Júnior et al ( 2010), que ao trabalharem com o clone IPA 20 do mesmo gênero, em ambiente controlado, em vaso e adubado com doses de 4,25 g vaso -1 de P2O5 e 4,05 g vaso -1 de K2O encontraram produtividade de 86,25 g planta -1 .…”

O experimento foi desenvolvido na estação experimental do Instituto Nacional do Semiárido – INSA, em Campina Grande, Paraíba, Brasil. Foi conduzido em sistema irrigado, com as variedades Orelha de Elefante mexicana, Baiana e Miúda e 4 níveis de salinidade com turno de rega de 7 dias, corrigido a cada irrigação, com base na lisimetria de drenagem. Utilizou-se um fatorial 3 x 2 x 4, com delineamento em blocos casualizados, com 6 repetições. As avaliações ocorreram 365 dias após o início dos tratamentos para produção de massa fresca (PMF) e massa seca (PMS). A variedade Orelha de Elefante Mexicana (OEM) apresentou uma menor variação dentro dos níveis de salinidade, contudo a variedade Baiana apresentou o maior PMF com 1,7 kg por planta e para PMS a Miúda apresentou a maior produção com 180,2 g por planta. A variedade OEM destacou-se como a mais tolerante a irrigação com água salinizada. Palavras-chave: estresse salino, condutividade elétrica, cactáceas, irrigação, tolerância. FELIX, E. S.; ARAÚJO, J.

PERFORMANCE OF FORAGE CACTUS VARIETIES SUBJECTED TO DIFFERENT LEVELS OF SALINITY 2 ABSTRACT The objective was to evaluate the development of forage palm varieties resistant to Cochonilha do Carmim irrigated with saline water. The experiment was carried out at the INSA experimental station in Campina Grande, Paraíba, Brazil. It was conducted in an irrigated system, with the OEM, Baiana and Miúda varieties and 4 salinity levels with a 7-day irrigation shift, corrected for each irrigation, based on drainage lysimetry. A factorial 3 x 2 x 4 with a randomized block design with 6 repetitions was used. The evaluations occurred 365 days after the beginning of treatments for PMF and PMS. At 365 days of treatment, it was found that the OEM variety showed a smaller variation within the salinity levels, however the Baiana variety showed the highest PMF with 1.7 kg per plant and for MS the Miúda presented the highest production with 180.2 g per plant. The OEM variety stood out as the most tolerant to irrigation with saline water. Keywords: saline stress, electric conductivity, cactaceae, irrigation, tolerance.

A B S T R A C TThe objective was to evaluate the application of agrometeorological indicators of water use efficiency for cactus forage, cv. "Miúda", aiming at the analysis of the contribution of the water increase in crop production systems. The experiment was conducted in the municipality of Serra Talhada, State of Pernambuco. The experimental design was randomized blocks with three replications, and treatments composed for two water regimes, the first equivalent of 756 mm.year -1 (around the climatological normal) and another 493 mm.year -1 (below the climatological normal). At the time of the harvest were obtained biometric variables and crop biomass. Through these latest data and water depth received by the crop were calculated Water Use Efficiency (WUE), Water Economic Productivity (WEP), and Irrigation Water Productivity (IWP). The EWP was evaluated assuming the sale of cladode for animal feed and as "seed". There were no effects of increasing water on the growth, productivity and agrometeorological indicators (p>0.05). However, it was noticed a decrease in 42% and 22% on fresh and dry matter production, respectively. Considering the WUE, the production of fresh and dry matter were 59.27 g.ha , respectively. It is concluded that the agrometeorological indicators of water use efficiency can be used for evaluation performance of the cactus forage.

The objective of this study was to evaluate the forage yield and morphological responses of 34 cactus pear (Nopalea cochenillifera and Opuntia ficus indica) genotypes. The genotypes were planted in a randomized complete block design, with 34 treatments and three replicates. After 330 days of cultivation, morphological characteristics, plant mortality and pest and disease occurrence on the plants were assessed, and plant cutting was performed. Multivariate analyses were performed to assign the 34 cactus genotypes to homogenous groups. The average Euclidian distance was adopted as a dissimilarity measurement for use with the standardized data Variables with relatively high levels of independence among the agronomic categories and with biological importance to animal nutrition and forage yield were assessed. To identify associative effects, Pearson’s correlation analysis was performed among all the studied variables. The formation of five distinct groups was observed, and some morphological responses correlated with the productivity characteristics. Green mass production was positively correlated with dry mass production, water accumulation, water-use efficiency, water accumulation and cladode number per plant. The following genotypes had remarkably high yields of dry and green mass, a greater ability to accumulate water and relatively high water-use efficiency and support capacity: Negro Michoacan (V07), Tamazunchale (V12), California (V14), Orelha de Elefante Mexicana (V17), and Amarillo 2289 (T32).
