RESUMO

O trabalho foi desenvolvido com a finalidade de se aquilatar diferenças nos níveis críticos entre os cultivares Agroceres 256, Agroceres 504, Centralmex, H-7974 e Piranão. O ensaio foi conduzido no Município de Piracicaba, SP, tendo como suporte um Regossol arenoso de média fertilidade. Foram seguidas as práticas culturais comuns e a adubação constuiu de 83 g da fórmula 30-120-70, por metro linear no plantio e 33 g/ /metro linear da fórmula 50-0-45 em cobertura. A população de plantas foi de 50.000 por hectare. Aos 60 dias após o plantio e no florescimento foram coletadas as folhas (+4) e da inserção da espiga, para fins de diagnose. Foram observadas diferenças nas concentrações de P, K, Ca, Mg e Fe, na matéria seca das folhas (+4) dos cultivares aos 60 dias após o plantio, e nas concentrações de P, K, Cu e Fe na folha da inserção da espiga, na fase de florescimento. Diferenças estas que não afetam a produção de grãos. A extensão das diferenças entre cultivares nos níveis foliares dos nutrientes depende da época de amostragem. As coletas feitas em épocas fisiológicas determinadas tende a diminuir estas diferenças. Cultivares com potenciais de produção semelhantes podem ser tratados igualmente em relação à análise de folhas, desde que se adote uma faixa de teores adequados.

SUMMARY

The objective of the present work was to examine the differences in nutrients levels between the cultivars Agroceres 256, Agroceres 504, Centralmex, H-7974 and Piranão. The experiment was carried out in the municipality of Piracicaba, State of São Paulo, Brazil. The soil type was a sandy "Regossol" of medium fertility. Common cultivation practices were followed, and the fertilizer used consisted of 83 g of a formula: 30-120-70, per meter length at planting, and 33 g of the formula 50-0-45 per meter length as a dressing. The plant population density was 50,000 per hectare. Sixty days after planting and at flowering the leaves (+4) and the ear leaf, respectively, were harvested for diagnostic purposes. It was observed that differences exist in the concentrations of P, K, Ca, Mg and Fe in the leaf (+4) dry matter of the cultivars at 60 days after planting, and in the concentrations of P, K, Cu and Fe during flowering. Such differences did not affect the production of grain. The extent of the differences between cultivars in the levels of nutrients in the leaves depends on the period of sampling. The harvestry of leaves at determined physiological periods tend to dimi-nuish these differences. Cultivars with similar yield potential may be regarded equally in relation to their leaf analysis, provided that one adopts an adequate range of nutrient levels.
