Abstract
In the present study aimed to evaluate the use of metric variables as non-destructive method for estimating the green mass of prickly pear in semi-arid environment. The correlation between the weight of green mass, volume and real volume estimated by the variables of length, width and thickness of the cladodes was investigated in 500 cladodes of prickly pear, variety IPA20. The cladodes were collected in five different size classes (length). The coefficient of determination for the variables of weight and volume of real (0.922) confirmed the correlation between variables. The determination coefficients for the variables of weight and volume were estimated 0.922, 0.94, 0.971, 0.864, 0.889 and 0.982 for classes A, B, C, D, E and all classes together respectively. Except for class B, which also showed significant, high correlation was observed between the variables tested. Thus, we conclude that the use of tape and the caliper can be important tools in the estimation of green mass production of cactus pear.
