Weed Early and Often. Crop yield is the term for the amount of harvested production per unit of land. In the U. Acre — unit of land used to measure cropland in the U. An acre is 4, square yards, and there are acres in one square mile.
The minimum amount realizable from a well cultivated hectare of land is N, A farmer may go home with almost N, profit margin or more in three months, all things being equal. Cost of harvesting and grain shelling:. What is a good corn yield per acre? During , the U. At the county-level, corn yields ranged from less than bushels per acre in portions of the Southeast and the western Corn Belt to greater than bushels per acre across many portions of the Corn Belt.
How long does Maize take to mature? What is the expected yield of maize per hectare? Depending on the farming process used and type of maize seeds hybrid seeds or not planted, you may be able to either generate about 10 tonnes of maize yield per hectare or about 2 tonnes of maize yield per hectare.
How many bags of beans can an acre produce? Bean yields in many farms are, however, very low averaging 1 to 2 bags per acre. But if grown well farmers can get up to 11 bags. What is the spacing of maize? Fourth, for good growth and development, maize should be planted at the right spacing. The recommended spacing is 75cm between rows and 25cm for plants. Hybrid genetics is the most important factor in determining the number of potential kernel rows.
However, plant stresses can reduce the actual number of kernel rows produced. The number of kernel rows on an ear is almost always an even number because the first kernel initials are split, forming two rows from one. Kernel rows can be visually observed by dissecting ear shoot as early as the late vegetative stages.
Kernels per row Kernels per row are determined, developmentally, at approximately the 6th leaf stage V6 up to tasseling VT , with the maximum number of ovules set about one week before silks begin to emerge.
Plant stress at this time can reduce the number of ovules that develop. It has been estimated that there are up to 1, ovules per ear.
The number of ovules that are fertilized and retained ultimately determines kernels per row. Kernel abortion will occur as late as the milk stage R3 if plant stress occurs to the point where insufficient resources become available. Kernel abortion occurs starting from the tip of the ear. The measurement of kernels per ear can be determined as early as the milk stage R3.
To determine kernel rows per ear and average kernels per row, record the number of complete kernel rows per every fifth ear in the row.
This will give you the number of kernels per ear. If row number changes from butt to tip, estimate an average row number for the ear. If kernel numbers per row are uneven among the ear rows, estimate the average value for kernels per row. Kernel weight Kernel weight is largely determined from the blister R2 through dent R5 stages. It is common to use a generic, assumed value for kernel weight when determining yield estimates.
Common kernel weights range from 0. For yield estimation, a correction factor of 65, to , kernels per pound bushel is used; 90, is most commonly used. If your crop is subject to stress before R6, starch accumulation in the kernels is reduced, so you will have a lower kernel weight. Since a total of 1, farmers have participated in the PEPS contest. Profit groups were determined by ranking contestants in quintiles by division, district and year.
The variability is mostly due to the way in which fertilizer costs are calculated using yield level and consequent P and K removal rates. Total acre cost of production between the top and bottom profit group is similar, but grower return is not, due to substantially higher yield Fig. Better efficiency lower cost per bushel occurs with higher yields.
Table 1. Top corn farmers have 1. Farmers in the top profit group tend to use land with lower yield potential, rotate more frequently, plant about 3 to 6 days earlier, and make 0.
