The experiment was designed with two
cropping patterns following randomized complete block design with six dispersed replications.
Happy Seeder (HS) technology in rice-wheat
cropping system, gives an advantage of direct drilling of wheat into loose as well as standing stubbles of rice in a single pass of the field, giving an additional benefit of 60% against conventional sowing (Qamar et al., 2012).
When nitrogen fertilizer is restricted in supply, biological nitrogen fixation is an important source of nitrogen in legume-cereal
cropping systems.
"And as in conventional
cropping systems, cover crops can help organic producers improve their environmental footprint with sustainable practices that help reduce soil nitrogen losses--an issue that is becoming increasingly important for agricultural producers."
As regards cost benefit ratio, the highest ratio was received in case of rice-lentil (1:2.38)
cropping system followed by rice-canola (1:1.96) and rice-wheat-mungbean (1:1.78) as against the existing
cropping pattern (rice-wheat) which gave the ratio (1:1.56).
* Polyculture (intercropping) is a
cropping system in which two or more crops are grown together on the same field during a growing season.
However, incorporating them into summer annual
cropping systems, especially following corn grain in the upper Midwest, presents challenges because of the short establishment window after grain harvest limited by temperature and possibly water.
The most significant change in
cropping patterns in Saskatchewan over the past 20 years, and perhaps since agriculture became well established in the province, has been the increase in land sown to specialty crops.
Let's try and blow away the smoke surrounding cover
cropping and talk about what we do and don't know.
In the U.S., 64% of the increased yield in the corn crop since the 1920s can be attributed to genetic improvements; the rest to better
cropping practices.
Not only will they require hard-to-get spare parts and petroleum-based fuels, but they were developed for different soils and
cropping patterns.
Multiple
cropping was a form of poly culture, he said and added it can be double
cropping in which second crop was cultivated after harvesting the first one.
