Nutritional balance and number of leaves as variables for yield prediction of the Horn plantain

Vianel Rodríguez, Ana da Silva, Orlando Rodríguez

Resumo


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.
