Desenvolvimento inicial da mamoneira, girassol e nabo forrageiro adubados com lithothamnium

Resumo

In order to evaluate the effect of lithothamnium fertilizer on the initial development of castor bean (Ricinus communis L.), sunflower (Helianthus annuus L.) and radish (Raphanus sativus L), IAC Al Guarany, Embrapa 122 and AL 1000, respectively, developed three experiments inside the greenhouse, where each plant was grown in pots with a capacity of 10 dm 3 . The experiment in the three experiments was randomized blocks with five treatments and three repetitions where the treatments consisted of different doses of lithothamnium (0, 100, 200, 400 and 600 kg ha -1 ). The plant castor bean, radish and sunflower were collected 60 days after sowing for evaluation. The characteristics evaluated were: plant height (cm); stem diameter (cm); dry matter of leaf; flowers and fruit stalk. Doses of lithothamnium influenced the growth of castor, sunflower and radish. The best results for the sunflower, radish and castor beans were found by applying the average doses of 428, 432, 527 kg ha -1 lithothamnium respectively.
