Resumo: | There are few studies about the nutritional requirements and dry matter accumulation due to the mineral nutrition of Helianthus sp. Since this plant presents a high requirement of boron it is a good indicator of the boron deficiency in the soil. A study was curried out in pots in the greenhouse to evaluate the effect of different level of lime and of boron on growth and dry matter accumulation. The soil's pH improvement was done with lime in the folowing dosages: 15% (0 t/ha), 40% (1t/ha), 60% (2t/ha) and 80% (3t/ha) of bases saturation and the boron leveis (boric acid) were 0,1 and 2mg dm3 After 33 days of plantation the aerial part of the heilanthus plants was cut off and dried in greenhouse and, after that, evaluated in terms of dry substance yield. The increase of soil basis saturation to 40% resulted in a higher accumulation of dry substance which indicated that the 1 ton/ha dosage was considered sufficient to reach a satisfactory pH. The boron level at 1 pprn reached a higher value of dry substance which differs significantly from the helianthus yield with the absence of boron. |

Poucos são os estudos sobre as exigências nutricionais da planta de girassol. Em razão de sua exigência a esse micronutriente, o girassol é uma forte indicadora de deficiência de boro no solo. Com o objetivo de avaliar o efeito de diferentes doses de calcário e de boro na produção de matéria seca do girassol foi realizado um estudo em casa de vegetação. A correção do pH do solo foi realizada com minercaf nas seguintes dosagens 75% (O t/ha), 40% (1t/ha), 60% (2t/ha) e 80% (3t/ha) de saturação por bases e as doses de boro (ácido borico) foram 0,1 e 2 mg dm3. Após 33 dias do plantio foram colhidas as partes aéreas das plantas que foram secas em estufa e posteriormente pesadas. A elevação da saturação por bases do solo para 40% resultou em maior acúmulo de matéria seca. O nível de boro a 1 mg dm3 proporcionou maior valor de matéria seca diferindo significativamente do rendimento do girassol na ausência de boro.
