write the requirements for rice and wheat crops
Answers
Grains and legume crops are cultivated throughout the world in every imaginable growing condition, from tropical swamplands to arid deserts. Rice (Oryza spp.), wheat (Triticum spp.), corn (Zea mays) and soybeans (Glycine max) are four of the most widely cultivated staple crops in the world and can also be grown by home gardeners on a limited scale. Each of these annual crops has specific growing requirements. For example, the planting season for eRice originates in tropical lowlands and requires a long, warm growing season but is cultivated commercially in California and some of the Southeastern states. It thrives in USDA hardiness zones 9b through 10a. It can be grown wherever nighttime temperatures stay above 60 degrees for at least three months of the year. Rice is traditionally grown in flooded fields, though this is not necessary for home production. However, it does require constant soil moisture to grow. Plant rice in poorly drained areas, if possible, and do not let the soil dry out. The growing area should be kept weed-free and well-fertilized with a source of nitrogen.ach varies depending on the local climate.Wheat
Wheat is an annual grass that grows well in cold temperate regions. It thrives in USDA zones 7a through 10b. There are two main types -- winter wheat and spring-planted varieties. Winter wheat germinates in fall and needs to go through a period of cold weather to produce its seed early the following summer. Varieties for spring planting are more heat tolerant and ripen in late summer or fall. Wheat can often be grown without supplemental irrigation except in very arid areas. It is not a heavy feeding crop, but excessively sandy or heavy clay soils should be amended with compost prior to planting.
Corn
Corn can be grown as a grain or vegetable, though there are ornamental varieties that can be dried and used in decorative arrangements. It is a warm-season annual that germinates easily when soil temperatures reach 70 degrees and thrives in USDA zones 9b through 10b. It is one of the heaviest feeding crops, growing best in soils that have been amended with composted manure prior to planting. It needs regular irrigation throughout the growing season and should be planted only in well-drained soils. Good pollination is essential for growing full, well-formed ears of corn. Planting three or four short rows together rather than one long row is the key to effective pollination.
Soybeans
Soybeans are an annual legume that can be eaten as a fresh vegetable, used as a dried bean or made into a wide variety of soy products. Sow seed in spring after soil temperatures have reached 70 degrees or more. They thrive in USDA zones 7 through 9. They are a bush-type bean that is easy to grow and can be productive even in poor soils, as long as they are loose and well-drained. Nitrogen fertilizer stimulates bushy, dark green growth but may result in reduced bean production. For use as a steamed vegetable, harvest when the seed pods are full but still green. For dried beans, wait to harvest until the plants have dried and turned brown.
1. Soil type required is clay or clay loam because it has good water retention capacity.
2. Suitable temperature is above 25°c.
3. Annual rainfall required is 100cm.
*Requirements for wheat crop*:-
1. Well drained fertile soil and heavy textured soil with lime, clayey loamy soil or black soil required.
2. Temperature required is 10°-15° during growth and 25°-28° during ripening.
3. Annual rainfall required is 50 to 75 cm.
