Factors to consider in hybrid election

Source: INTA

When projecting the you surrender of a hybrid one it is always important to know their behavior in the precedent years, previous to choose the most suitable in particular for each situation and region.

Nevertheless, the election of the best to cultivate for yes it doesn't only assure us the final success in the crops yield.

In consequence they are also important decisions on the floor type elect (profile depth , agricultural history, predecessor crops), farm, dates and installation type, sow density, control of overgrowths and fertilization.

The type of crossing of an hybrid allows to locate us, for example, on the possible behavior that can have, before a period of hidric stress in the bloomer stage. The hybrid triples adapt better to be sowed in more limited atmospheres, because the biggest bloomer period that possess the make it more elastic. The cost of the seed is more economic. The hybrid ones simple on the other hand, are recommended for those floors without impediments, with good capacity of water storage , where the farming can express its potential production.

The grain type is a characteristic that again is taking importance. At the moment they are little the hybrid ones with yellow jagged grain that exist, characteristic that prevailed until some years ago. Those classified as half-jagged possess reason why more than 75% of the horny endosperma in the commercialization standard hard grains they are considered. In the new materials a tendency is observed to return to the hybrid of harder grain, so much orange as something redder. This condition is very looked for and generally discounted with a surcharge about the slate value.

The value of relative maturity indicates us in general form the differences to wait among hybrid in the percentage of humidity to the crop. If two farm that were sowed in the same date possesses 6 units of difference to the crop (for e.g.: 112 and 118) it would be equal to that in those hybrid ones a difference of 3 units of humidity would be expected (for e.g.: 14,5% in the first one and 17,5% in the second). In a comparison among the relative maturity of two materials, it is calculated that to the units of difference that they exist it should be considered the half in units of humidity. With this value it is indicated independently in general form the maturity of a hybrid one of the sow date and other environmental factors that could impact in the period to crop.
