- Abstract
The objective of this study was to evaluate the physiological potential of stylosanthes seeds cv. Campo Grande in response to coating with zinc and boron. The treatments were: T1 - uncoated seeds; T2 - seeds coated with calcium silicate; T3 - 80 g of B + 60 g of Zn.kg-1 seeds; T4 - 120 g of B + 90 g of Zn.kg-1 seeds; T5 - 160 g of B + 120 g of Zn.kg-1 of seed and; T6 - 200 g of B + 150 g of Zn.kg-1 of seed. The seeds were evaluated by germination test, speed index and mean time of germination (GSI and MGT), seedlings emergence test, speed index and mean emergence time (ESI and MET), shoot and root length (SL and RL), leaf area (LA), number of nodes (NN) and shoot and root fresh (SFW and RFW) and dry weight (SDW and RDW). Coating reduced the germination and seed vigor. Micronutrients favored plants development, after its establishment. The coating with 120 g of B + 90 g de Zn.kg-1 of seed favors the growth, development and nodulation of the plants.
