Produtividade de variedades de palmas forrageiras no sistema de cultivo sobre o solo.

Abstract

The cactus pear is of fundamental importance for small, medium and large cattle ranchers in the northeastern semi-arid region, being considered a forage support essential in the voluminous feeding of these animals. The research aimed to to evaluate the productivity of three varieties, being from two distinct genera Nopalea and Opuntia, as well as the cultivation system on the soil, and how specific to diagnose the leaf area of ​​the varieties and identify the occurrence of pests and diseases. The experimental area is located in the rural area of ​​the municipality of Jaçanã-RN. The period corresponding to the evaluations of this stage was seven months starting on January 8 and ending on July 8, 2022, corresponding to a cut of the larger research. The investigated variables were the systems of cultivation, number of cladodes, area of ​​cladodes and productivity. The results if were promising, as the soil cultivation system and the studied varieties has been confirming the finding that the cultivation system on the ground and the ear palm Mexican elephant has demonstrated that this technological innovation is viable economically and in terms of time an alternative for the cultivation of cactus pear. It is concluded that the productivity of the investigated varieties Opuntia stricta, Nopalea cochenillifera and Nopalea sp. obtained promising results in relation to the cultivation on the ground, but with considerable prominence of Opuntia stricta. compared to number of cladodes among the varieties, it can be observed that the palms cultivated in cultivation system on the soil stood out in relation to the conventional system, even these are statistically similar, being the variety Nopalea cochenillifera the one that produced the highest number of cladodes. That pests and diseases did not promote imbalance in the cultivation of cactus pears.
