Evidência isoenzímica sobre a origem interespecífica do café Piatã [PDF]
Bragantia, 1995 Encontrou-se, anos atrás, em uma lavoura de Coffea arabica (2n = 44), uma forma de café bastante distinta das demais. Inicialmente, julgou-se tratar de um cafeeiro autotetraplóide de C. liberica (2n = 22) ou de C. dewevrei (2n = 22). Estudos morfológicos e citológicos de tal cafeeiro, denominado Piatã (prefixo C387 da Seção de Genética do IAC), assim ...

Is organic fertilizer application a viable alternative to synthetic fertilizer for Piatã grass?
Tropical Grasslands-Forrajes Tropicales, 2021 Organic fertilizer in many cases can replace mineral fertilizers and in consequence reduce production costs and improve soil quality. Thus, the aim of this work was to evaluate productive, morphogenic and structural characteristics of Piatã grass (Urochloa brizantha) fertilized with urea, organic compost and biofertilizer throughout a year.

Dry matter intake by beef steers on Piatã palisadegrass (Brachiaria brizantha cv. BRS Piatã) pasture
Tropical Grasslands - Forrajes Tropicales, 2013 Beef production in Brazil is primarily based on tropical pastures and 85% of these pastures are Brachiaria brizantha cv. Marandu. Such a monoculture could prove disastrous, if some pest or disease emerged. With the goal of further diversifying pastures and contributing to the sustainability of the pasture production system, B. brizantha cv.

Perfilhamento do capim-piatã submetido a regimes de desfolhação intermitente [PDF]
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2019 RESUMO Objetivou-se avaliar o perfilhamento da Brachiaria brizantha cv. Piatã, como base para identificação das frequências e alturas pós-corte mais adequadas para essa gramínea forrageira. Em um esquema fatorial 2 x 2, foram estudadas combinações entre duas frequências de corte (95% e máxima interceptação de luz, ILmax) e duas alturas pós-corte (15 e ...
