Effect of herbicides on rice yield components

Effect of herbicides on rice yield components

Two brazilian rice cultivars IAC-165 and BR-IRGA 409 were seeded in pots and cultivated in a screenhouse under the climatic conditions of Goiânia, state of Goiás, Brazil. The herbicides bentazon, 2,4-D, propanil, butachlor, oxadiazon, thiobencarb and pendimethalin were applied to the plants on the recommended rates and dates to evaluate their effects on some rice yield components. The herbicides butachlor and oxadiazon only showed a trend to reduce production, without any significant difference from the control. On the other hand, 2,4-D was the most injurious of the herbicides to the rice production, reducing the number of panicles per plant and filled seed percentage of the cultivar BR-IRGA 409. The herbicides bentazon and propanil applied at post-emergence and thiobencarb applied at pre-emergence were the least phytotoxic products, not affecting any of the evaluated parameters.

As cultivares de arroz IAC-165 e BR-IRGA 409 foram semeadas em vasos e cultivadas no interior de um telado, nas condições climáticas de Goiânia (GO). Os herbicidas bentazon, 2,4-D, propanil, butachlor, oxadiazon, thiobencarb e pendimethalin foram aplicados às plantas nas doses e épocas recomendadas, para avaliar seus efeitos sobre os componentes da produção de arroz. Os herbicidas butachlor e oxadiazon apresentaram apenas tendência de reduzir a produção; não se observaram diferenças significativas desses produtos em relação à testemunha. O 2,4-D foi o herbicida que mais prejudicou a produção, tendo reduzido sobretudo o número de panículas por planta e a percentagem de espiguetas cheias da cultivar BR-IRGA 409. Os herbicidas bentazon e propanil aplicados em pós-emergência e o thiobencarb em pré-emergência revelaram-se os produtos menos fitotóxicos: não afetaram nenhum dos parâmetros avaliados.
