RODRIGUEZ, Vianel; SILVA, Ana da and RODRIGUEZ, Orlando. Nutritional balance and number of leaves as variables for yield prediction of the Horn plantain. Pesq. agropec. bras. [online]. 2005, vol.40, n.2, pp. 175-177. ISSN 1678-3921. http://dx.doi.org/10.1590/S0100-204X2005000200011.
The objective of this work was to develop a regression equation for yield estimation of the Horn plantain crop (Musa AAB subgroup platano cv. Horn), with the relationship between the Nutrient Balance Indexes (DRIS-NBI) (X1) and the number of leaves of the plant (X2). Totally at random, 398 foliar samples were collected. The regression equation developed is Y= 30.351** - 8.644** log X1+ 0.27502*X2, with R2 of 0.6206***, with normal distribution of the residuals. By the developed equation, the potential yield of any Horn plantain plantation in the sampling area could be predicted.
