COMPORTAMENTO DE VARIEDADE DE PALMA FORRAGEIRA RESISTENTE A COCHONILHA-DO-CARMIM EM CONDIÇÕES DE SUB-IRRIGAÇÃO NO CARIRI PARAIBANO

Abstract

The objective of the research was to evaluate the behavior of varieties of cactus-resistant cochineal carmine in the sub-irrigation conditions in Cariri Paraibano. The survey was implemented in the town of Serra Branca, Caatinga, River Basin Paraíba, semiarid region, mesoregion Borborema, Micro-region of West Cariri from Above Light District. After preparing the area for plowing gave the rackets of varieties of ear-elephant- Mexican Opuntia sp; Sweet or Tiny Nopalea cochenilifera and Bahia or Sertânea Nopalea sp at the National Institute of Semi-Arid INSA / MCTI, located in the city of Campina Grande, Paraíba. After curing or healing of at least five days rackets Ear-of-elephant-Mexican and Tiny were planted on September 6, 2014 and the Bahian or Sertânea on October 23, 2014 obeying the spacing of 1, 5 mx 0.50 mx 0.50 m in double rows in contour system. Twenty-three were planted palm ranks of which thirteen palm double rows Tiny 827 rackets, three consortium in rows with Gliricidia sepium planted in the center of the double rows. The Bahia or Sertânea palm were planted five double rows, one consortium, totaling 651 rackets and last five rows of palm Ear-of-elephant-Mexican, with a consortium, totaling 708 rackets. The girl variety began sprouting five days after planting. Already-ear elephant Mexican started sprouting at twenty-five days after planting. The palm-ear elephant without the Mexican consortium with gliricídia presented for primary racquets in the top row of median values of 3.40 shoots per plant which means that at a spacing of 1.5 mx 0.50 m x 0, 50m at a ratio of 20,000 plants / ha quantitative 68,000 primary green shoots with a unit weight of 0.210 kg which is equivalent to 14,280 kg / ha. The results of the palm-ear elephant-Mexican consortium with gliricidia can be verified that for the top rows of the primary ramifications occurred in the ratio of 2.90 unit / plant making rackets 58,000 / ha. Assuming an average 0.250 kg / racket can be total green mass of 14,550 kg / ha. These little in values clash with the situation without consortium which may mean that does not even occur gliricídia influence of the agro-ecosystem for the time searched. Regarding the behavior of Gliricidia plants the values found for the gliricídia consortium / palm girl far superior way both height and diameter than for gliricídia consortium / palm-ear elephant-Mexican.
