Estudios sobre la nutrición mineral del sorgo para grano. X. Eficiencia nutritiva comparativa entre sorgo para grano maíz
1980
This investigation was designed to estimate and to compare the nutritional efficiency of 5 grain sorghum and 6 corn cultivars. In the greenhouse, sorghum and corn plants were grown in nutrient solution until maturity, being then harvested, separated in parts and dried. Samples were analysed for total N, P and K. The nutritional efficiency was calculated by the following formula. E = grain yield (g) nutrient contained in the vegetative part of the plant (g) x plant cycle (days). The results obtained allowed for the conclusion that there is need for further studies to establish conclusively the concept of nutritional efficiency for grain sorghum. There were significant correlations between production and N and P nutritional efficiency for corn. Grain sorghum yielded more than corn and the nutritional efficiency was also higher.
