- Abstract
This study aimed to analyze and compare the agronomic characteristics and development of the root system through digital image processing of different cultivars of tropical grasses of Brachiaria and Panicum genera. The experiment was carried out at an experimental station of the Research, Rural extension and land regularization company of Paraiba – EMPAER in Alagoinha - PB, in a rainfed agriculture system. Through June 2019 to 45 days after sowing, the grasses were cut for aerial part evaluation (biomass composition, forage yield, root system (volume and surface area) of the cultivars Mombaça, Tamani, Zuri, Massai, Piatã and Ipyporã. Occurred difference between cultivars for all variables analyzed, except for the leaf-stem ratio. The cv. Mombaça presented the best agronomic and root results, being the one that best adapted the edaphoclimatic conditions of the region. On the other hand, Ipyporã was the least expressive for forage yield and water efficiency. Through root image processing, a diagnosis is possible that reflects the forage yield of the genera Brachiaria sp. and Panicum sp.
