Effect of glyphosate and P on the growth and nutrition of Coffea arabica cultivars and on weed control
The effect of the phosphorus (P) and glyphosate interactions on the growth and nutrition of Arabica coffee cultivars ( Coffea arabica ), as well as on the control of Ipomoea grandifolia and Urochloa decumbens , was evaluated. Catuaí-Amarelo/IAC-62 and Catuaí-Vermelho/IAC-144 cultivars did not show g...

Zusammenfassung: | The effect of the phosphorus (P) and glyphosate interactions on the growth and nutrition of Arabica coffee cultivars (
Coffea arabica
), as well as on the control of
Ipomoea grandifolia
and
Urochloa decumbens
, was evaluated. Catuaí-Amarelo/IAC-62 and Catuaí-Vermelho/IAC-144 cultivars did not show glyphosate poisoning, regardless of the soil P content. However, glyphosate reduced the growth of Catuaí-Vermelho/IAC-144. In addition, the soil P content influenced the height, leaf area and dry matter of Catuaí-Amarelo/IAC-62, and the absorption of P and Ca in both cultivars. On the other hand, glyphosate efficiently controlled
U. decumbens
but not
I. grandifolia
. Glyphosate effectiveness on
I. grandifolia
decreased as the soil P content increased. In addition, the soil P content and the glyphosate influenced the P content in
I. grandifolia
and
U. decumbens
plants. The soil P content influenced the growth and absorption of other nutrients by coffee plants as well as glyphosate effectiveness on weed control. |
