Productive capacity of Brachiaria brizantha (Syn. Urochloa brizantha) cv. Marandu subjected to liming and nitrogen application

摘要

This work aims to evaluate production of Brachiaria brizantha (Syn. Urochloa brizantha) cv. Marandu subjected to liming and nitrogen fertilization on climatic conditions in the municipality of Humaitá State of Amazonas, Amaz?nia, Brazil. For both, pot experiment with soil after sowing was kept in a greenhouse at the Institute of Agriculture and Environmental Education (IEAA / UFAM). Part of the soil pots was incubated with limestone while the remainder of the vessels is used without liming ground. Different nitrogen levels (0, 100, 0 200 and 300 kg.ha-1) were also applied in a 2x4 factorial design with four replications. To assess the growth and development of plants, number of tillers, along with weight of fresh and dry matter were used in the first, second and third cut. Liming enables further growth and development of B. brizantha (Syn. U. brizantha) plants and enhances the plant response to nitrogen.
