Results on bioenergetic potential of some sweet sorghum hybrids cultivated under psamosols conditions in Southern Oltenia

Abstract

Sorghum bicolor L. Moench is a herbaceous annual C4-type plant, with a high ecological plasticity because it can be grown in tropical, subtropical, temperate and semi-arid regions, harnessing soils with reduced natural fertility, from the category of sandy soils. Studies on 5 sweet sorghum hybrids studied under psamosols in southern Oltenia highlight a bioenergy potential in the milk-wax phase of the grain, ranging from 60847.4-89338.65 Mcal / ha, with a maximum in the hybrid Shaşm 2, which achieved a distinctly significant difference in production, compared to the average production of hybrids. The results recorded in sugar sorghum production were positively correlated, significantly distinct with leaf index determined during the flowering of the plants (r = 0.9854**).
