Physiological Quality Seeds Of Bean In No-Tillage System Over Different Coverings Of Plants In Diamantina, Mg

The objective this work was evaluate the effect of different coverings plants on the physiological quality seeds of bean in no-tillage system in Diamantina-MG. The experiment was installed in the Campus 11 of UFVJM, in a Neossolo Quartzarenico Ortico tipico, in blocks randomized design, with ten treatments and four replicates. The treatments were constituted of control chemical and rubbed straw of 1) Brachiaria decumbens cv. Basilisk, 2) Brachiaria brizantha cv. Marandu, 3) Panicum maximum cv. Tanzania, 4) Panicum maximum cv. Mombaca, 5) Mucuna aterrina (black mucuna), 6) Calopogonio muconoides cv. Calopogonio, 7) Dolichos lab lab (lab lab), 8) Cajanus cajan (guandu), 9) Natural covering and 10) Conventional plantation where the bean plantation was made to cultivate Talisman. The physiological quality of the seeds was evaluated by the germination tests (first and final count); electric conductivity of the solute; weigh of 100 seeds; length and weight of the plants; index of germination speed and text of water of the bean seeds. The grass Panicum. maximum cv. Mombaca, Brachiaria brizantha cv. Marandu, B. decumbens cv. Basilisk and P maximun? cv. Tanzania produced dry matter in amount and uniformity for larger conservation of water and protection of the soil to make possible the no-tillage system. The quality of the seeds was not affected by the used soil handlings but had the influence of the climatic conditions in the maturation.
