Maturity of maize whole-plant and voting of corn hybrids after measure - Optimal maturity of maize whole-plant and constant animal production through leading the maize culture before harvesting by means of measurement of corn maturity

- With the grain-T-content can the time of harvesting, maximum of the yield and the quality of corn plant more exactly and thereby with least material and temporal expense in comparison to the T-content of the whole plant of different corn plant population are determined. The optimum for ensiling and the maximum of the yield are with the physiological maturity of whole plant next to identical and lie with the grain-T-content of 65% in the beginning stage of the maize corn. - The harvesting of the whole corn plant on the basis of the T-content of the whole plant can lead to maturity in the grain of under 55% and/or to insufficient concentration of starche and energy in the whole plant material. The T-content of the whole maize plant is at a certain maturity of corn and/or of starche only expression of the aging of the plant without cobs. For the improvement of the quality are higher cutting and/or feeding of concentrates the consequence in the practice. - The plant without cobs takes beside the grain a strong influence on the T-content of the whole plant. At T-contents of the plant without cobs over 30% should be explored the feeding value, before everything from mykotoxikological view. On these locations the crop is to be accomplished already before reaching the optimum of maturity and of maximum of yield. Therefore hybrids with a long harvesting time should be grown in the future only, which store intensely starche and display a high digestibility of plant cell wall at slowly drying of the plant without cubs. - The KRZ is for the declaration of a sort in a maturity group better than the SRZ and the grain-T-content than maturity for all using in the production of maize suitable.
