New method of estimation of pre-harvest yield in graniferous sorghum cultivation
In the absence of a practical and precise method for estimating pre-harvest yield of graniferous sorghum, it was proposed that such a procedure be developed. Samples of pan leaves from 23 graniferous sorghum hybrids were analyzed in which the correlations between different morphological variables an...

Samples of pan leaves from 23 graniferous sorghum hybrids were analyzed in which the correlations between different morphological variables and the weight of the grains contained in them were studied. The morphological variables evaluated were the diameter of the peduncle (DPP), the length (LP) and the width (AP) of the panicle. It was concluded that by means of a simple linear regression and using the DPP or the average AP of a sample of at least 50 panojas as the regressor variable, an accurate estimation of the weight of the grains in the panicle can be made. Ante la falta de un método práctico y preciso para estimar rendimiento precosecha de sorgo granífero se propuso el desarrollo de un procedimiento con esas características. Fueron analizadas muestras de panojas de 23 híbridos de sorgo granífero en las que se estudiaron las correlaciones entre diferentes variables morfológicas y el peso de los granos contenidos en las mismas. Las variables morfológicas evaluadas fueron el diámetro del pedúnculo (DPP), el largo (LP) y el ancho (AP) de la panoja. Se concluyó que mediante una regresión lineal simple y utilizando el DPP o el AP promedio de una muestra de por lo menos 50 panojas como variable regresora, se puede hacer una estimación certera del peso de los granos en la panoja.
