Study on the Adaptability of some Sorghum Hybrids in the Pedoclimatic Conditions of Jucu, Cluj County

Abstract

In the current context of global warming, the sustainable development of agriculture can be achieved by expanding the areas cultivated with drought-tolerant plants with high production potential. Sorghum caryopsis, to be intended for human consumption and animal feed, must be free of phytopathogenic agents and meet a series of essential quality conditions. Unfortunately, in unfavourable storage conditions (too high temperature and humidity), caryopsis is attacked by a wide spectrum of pathogens (Fusarium, Alternaria). In this context, the aim of our study is to evaluate the adaptability and productive potential of six sorghum hybrids, identification of pathogens presents on sorghum caryopsis, their quality indices, as well as mycotoxin content. From the data obtained from the notes, observations and analyzes carried out, we can conclude that the percentage of sick caryopses was high in all the hybrids analysed, the microorganisms identified on the caryopses belonged to the genus Fusarium and Alternaria and the mycotoxin content was very low in all the hybrids analysed. This research highlighted the importance of Sorghum which becomes an alternative because it needs only half of the rainfall required by corn (it succeeds even when there is less than 350 mm annual rainfall), being able to replace the corn crop when there are conditions for a poor corn crop.
