A 2018 study found that Bt-corn protected nearby fields of non-Bt corn and nearby vegetable crops, reducing the use of pesticides on those crops. Data from 1976 to 1996 (before Bt corn was widespread) was compared to data after it was adopted (1996–2016). They examined levels of the European corn borer and corn earworm. Their larvae eat a ...
The seed from selected plants is bulked for the next generation. This method is used to improve the overall population by positive or negative mass selection. Mass selection is only applied to a limited degree in self-fertilizing plants and is an effective method for the improvement of landraces.
About 65 million metric tons of GM corn grains and about 70 million metric tons of soybean meals derived from GM soybean become feed. [95] In 2014 the global value of biotech seed was US$15.7 billion; US$11.3 billion (72%) was in industrial countries and US$4.4 billion (28%) was in the developing countries. [89]
There are two methods for producing baby corn: either as a primary crop, or as a secondary crop in a planting of sweet corn or field corn. In the first method, a seed variety is chosen and planted to produce only baby corn. [2] Many varieties are suitable, but those developed specifically for baby corn tend to produce more ears per plant.
Intensive crop farming is a modern industrialized form of crop farming.Intensive crop farming's methods include innovation in agricultural machinery, farming methods, genetic engineering technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, patent protection of genetic information, and global trade.
Detasseling was used in the late 19th and early 20th centuries in the "ear-row" method of corn breeding. In this method, alternating rows of corn are detasseled and the seed from the detasseled rows is saved for planting the following season.
Hybrid seed is common in industrial agriculture and home gardening. It is one of the main contributors to the dramatic rise in agricultural output during the last half of the 20th century. [ 1 ] Alternatives to hybridization include open pollination and clonal propagation.
Combines generally chop and disperse straw as they move through the field, though the chopping is disabled when the straw is to be baled, and chaff collectors are sometimes used to prevent the dispersal of weed seed throughout a field. The corn sheller was almost identical in design, with slight modifications to deal with the larger kernel size ...
