Association of morphological and water factors with irrigated forage cactus yield

Abstract

A B S T R A C TThis study aimed to understand the relationship of morphological characteristics and actual evapotranspiration of forage cactus clones with their productive capacity under different water regimes. The data used in this study were collected between the years 2012 and 2013, in Serra Talhada, State of Pernambuco. The clones Sertânia IPA -IPA, Miúda -MIU and Orelha de Elefante Mexicana -OEM were submitted to three irrigation depths (2.5, 5.0 and 7.5 mm) and three irrigation intervals (7, 14 and 28 days). Cladode and plant morphology, accumulated actual evapotranspiration and yield were obtained at the moment of harvest. Pearson's correlation matrix was elaborated and, in the sequence, multicollinearity, canonical and path analysis were applied. There was no correlation of yield with the soil water supply and actual evapotranspiration of the clones (p > 0.05). Forage cactus yield was more associated with peculiarities of the morphological characteristics of the clones than with the different soil water supplies or the crop actual evapotranspiration. However, regardless of the water regime and clone, the vigor of the basal cladodes was highly decisive for the expression of the forage cactus productive capacity.Associação de fatores morfológicos e hídricos com a produtividade da palma forrageira irrigada R E S U M O Objetivou-se, neste trabalho, compreender a relação de características morfológicas e da evapotranspiração real de clones de palma forrageira com sua capacidade produtiva em diferentes regimes hídricos. Os dados usados nesta pesquisa foram coletados entre os anos de 2012 e 2013, em Serra Talhada, PE. Os clones IPA Sertânia -IPA, Miúda -MIU e Orelha de Elefante Mexicana -OEM foram submetidos a três lâminas (2,5; 5,0; e 7,5 mm) e três intervalos de irrigação (7; 14 e 28 dias). Dados morfológicos dos cladódios e da planta, evapotranspiração real acumulada e desempenho produtivo foram obtidos na ocasião da colheita. A matriz de correlação de Pearson foi elaborada e, em seguida, foram aplicadas análises de multicolinearidade, canônica e de trilha. Não houve correlação da produtividade com o suprimento de água e evapotranspiração real dos clones (p > 0,05). A produtividade da palma esteve mais associada a peculiaridades das características morfológicas dos seus clones do que aos diferentes suprimentos de água no solo ou à evapotranspiração real da cultura. Mas, independente do regime hídrico e do clone, o vigor do cladódio basal foi bastante decisivo para a expressão da capacidade produtiva da palma forrageira irrigada.

Growing, Production and Quality of Thornless Cactus Irrigated With Dairies Effluent

“…Such a similar result to those observed by Queiroz et al (2015) and Cunha et al (2012) in studies with forage palm and irrigation blades in semiarid region conditions. However, Barbosa et al (2017) observed an increase in the number of cladodes of 3 rd generation, resulting in greater CO 2 assimilative ability and photosynthetic activity, enhancing the cell division and the increase of fresh mass, dry mass, length and number of cladodes of the Mexican erect prickly pear (Opuntia stricta (Haw.) Haw.…”

“…In this work, only positive and significant (5%) effects of the orthogonal contrasts were observed for pH, and for C and CN at 1% probability, thus demonstrating the nutritional and water supply effects for the thornless cactus in a semiarid environment. Queiroz et al (2015), and Barbosa et al (2017) confirm that the macro and micronutrients coming from wastewater can enhance the cacti productivity in semiarid regions, even being the water supply fundamental to the plant performance in these climate condition (Oliveira et al, 2017;Klomjek., 2016). However, dairy effluents have high terores salts, including sodium, which can cause salinization and in agricultural areas sodification handled improperly reused.…”

Study of morphometric and ruminal parameters in santa inês sheep fed spineless cactus (Opuntia ficus-indica, MILL)

“…Within the Brazilian semiarid scenario, spineless cactus (Opuntia ficus indica Mill) is a highpotential forage resource, as this succulent forage is important for the herds, especially during prolonged dry periods, and it meets most of the water requirements of the animals (Barbosa et al, 2017) in addition to providing palatable feed. Spineless cactus is also considered a mucilagerich feed, with significant mineral levels, mainly calcium (2.0 to 5.7%), potassium (1.5 to 2.58%), magnesium (1.3 to 1.7%), and phosphorus (0.1 to 0.6%) (Wanderley et al, 2002).…”

It even has high levels of non fiber carbohydrates and low levels of neutral detergent fibers, making it an important feed alternative in semiarid regions (Barbosa et al, 2017).…”
