Start / Crops and productivity

Crop yield

Estimated soybean and corn yield from population, ears or pods, grains per unit and thousand-grain mass, in bags per hectare.

Estimated yield

Estimate soybean and corn yield before harvest from plant population, pods or ears per plant, grains per structure, and thousand-grain weight.

Bags per hectare by components

Harvest losses

Convert the grains fallen in a 1 m² frame into kilos, bags and reais lost per hectare, and compare with the crop's tolerance.

Grain lost at harvest, in bags and in reais

Degree-days

Accumulate degree-days from the daily temperature and estimate how many days are left for the crop to reach a stage, based on the base temperature and the total required by the cultivar.

Days for the crop phase, by accumulated degree-days

Plants per hectare and stand

Convert the plant count in 5 metres of row into plants per hectare and compare with the target population, as a percentage of stand.

Plants per hectare from the 5 m count

Production by components

Estimate wheat or rice yield from yield components: plants, ears, grains per ear, and thousand-grain mass, with harvest losses.

Germination, IVG, and vigor

Calculate the final germination, the first count, the germination speed index (IVG) and the mean germination time of a seed test.
