In Iraq, wheat and barley are the main crops, followed by dates, maize and rice. the central provinces, fruit trees, mainly citrus, are inter-planted in date palm orchards. Vegetables, mainly tomatoes and potatoes, are important irrigated crops.
However Kuldeep, there are several others cropping sequence aroung the country, for example: soybean or corn in the summer followed by wheat during the fall and winter
Cropping sequences is a rotation system approach in crop production that enabling the available natural resources to be preserved and more efficiently utilized. It is the growing of the succession of crops in time on one field in particular time.
In the region of the central humid pampas of Argentina, the monoculture of soybeans still persists as the only crop (25-30% of the surface), another 30% of the surface is sown with winter wheat, immediately followed by soybeans as the second annual crop, finally 40% of the surface is planted with corn (which is always alternated with Wheat / soybeans or with part of soybeans as the only crop.
Soil degradation always goes hand in hand with high proportions of soybeans as the only crop. While the best conservation alternatives combine Wheat / soybean one year, following corn, and ending with soybean: four crops in three years and using winter cover crops (grasses before soybeans or legumes before corn).
The objective of Cropping sequence is many; diversification for consumption, nutrition, market, soil fertility, disease/pest cycle break, sustainable use of resources. etc. The links below may help get better information: https://www.sciencedirect.com/user/error/ILP-VERIFY-1?errorContext=tpp-e5a7308d-a6e4-46ef-b675-80bf6d6e4a42#
Major part of arable land and gardens in 2006 was sown by cereals (67%), followed by oil seed crops (13%), forage crops (12%), sugar beet, vegetables, potatoes, tobacco, flowers, aromatic and other plants.
There is a livestock manure composting network in the BASQUE COUNTRY [between France and Spain] in which the solid manure produced by 82 farmers is composted at farm level. All compost piles are they flip mechanically according to a previously agreed schedule and the final product is sold.
Barley, wheat, rice, vegetables, corn (maize), millet, sugarcane, sugar beets, oil seeds, fruit, fodder, tobacco, and cotton are the most important crops. Yields fluctuate greatly from year to year, especially in rain-fed farming areas. Production date Iraq used to be the world's largest producer of dates.
