Under natural rainfall conditions, relay cropping (in which the soybean crop is seeded between rows of growing camelina plants) used less water than double-cropping
(whereby soybean seed is sown right after a camelina harvest, around mid to late June).
An important innovation is taking place in the cerrado region: a double-cropping
system called safrinha.
This research project aims to study the tolerance of winter crops for the dry summer cultivation and saline water irrigation and to select crops for double-cropping
scheme and a variety of crop rotation.
Another factor that may have contributed in this double-cropping
situation is the narrow spacing between wheat rows.
This can be achieved through double-cropping
, where a second crop is grown in the same production area as the first crop (Duval 2005; Santos et al.
The project is expected to enable double-cropping
(two harvests per year) of rice and horticultural crops, as well as to improve the productivity of rice and other crops by expanding the total cultivated area from 7,860 ha to 16,920 ha in the project area.
2000, 2003) in the annual double-cropping
(winter wheat and summer maize) regions of northern China since 1997.
Over-cultivation of [genetically modified] soy and double-cropping
has led to serious soil erosion in Argentina in the past," says Miguel Rivas, a third-generation Argentine corn farmer.
A second new protein production model, which also relies on ruminants, is one that has evolved in China, principally in the four eastern central provinces of Hebei, Shangdong, Henan, and Anhui--where double-cropping
of winter wheat and corn is common.
Ghost acres refers to a second crop following a first crop that was not harvested because of prevented planting or failed conditions because of damaging weather or related conditions, where the second crop is not normally planted in a double-cropping
situation in the area after the first crop is harvested.
The increase is attributed to a production shift from corn to potatoes as well as an increase in double-cropping
, according to the report.
The cultivated areas of early paddy and double-cropping
paddy totalled 11.
