Harvesting is the procedure of assembling the beneficial portion of a plant. This is performed at the period until all of the nutrient levels have formed and also the edible components have managed to reach the suitable stage of sophistication, which is when the plant is fully matured.A typical harvest occurs 10 to 15 days that after grain has achieved biological maturation, depending on the variety of grain.
When the grain reaches maturity, it seems to have a specialised moisture level and physical attributes that distinguish it from other grains. The duration of the developing cycles (that varies depending on the cultivar and variety) and the level of longer maturities of the grain are used to identify the most ideal time to harvest.Harvesting could perhaps arise whenever the grain has a moisture concentration in the range of 15-20 percent.
Obviously, the higher moisture content of the grain at harvest season, the greater the chance of losses due to moulds, insects, and growing conditions. Alternatively, the more grain is allowed to sit in the field (to allow for yet more dehydration of the grain), the greater the chance of damages to disintegrating of grains or assaults by birds, rats, as well as other parasites.
Harvesting
Peas and lentils are typically harvested manually using basic agricultural tools like a scythe or mechanically whenever the seeds are mature but have not yet been exposed. For manual harvesting, the crops are lifted up and left to completely dry before being harvested. Such a procedure must be carried out first in the morning, when the wetness of the night reduces the likelihood of destroying losses from occurring.
Chemical defoliants are applied to the plants under certain areas prior to harvesting in order to prevent them from becoming diseased. In order to avoid harvesting processes from being slowed down by too much plant matter, this procedure is meant to speed dehydration of the crops and decrease the amount of plant matter present. It takes roughly 80-100 man-hours per hectare of land to trim the plants with a scythe on average.
Harvesting Index Formula
It is calculated as the ratio of the pounds of grain harvested to the overall pounds of above-ground organic matter harveste.This proportion of grain to overall dry shoot matter (HI) is often used as a way of measuring reproductive performance in plants. Harvesting Index (HI) is analysed by connections among genotypes (G), environment (E), and crop management (M)
Harvest index is calculated as follows: lbs of grain divided by (lbs stover added by lbs grain).
