What is the meaning of rainfed?

Rainfed agriculture is a type of farming that relies on rainfall for water. Rainfed agriculture is distinguished in most of the literature from irrigated agriculture, which applies water from other sources, such as freshwater from streams, rivers and lakes or groundwater.

What is rainfed in geography?

1. Filled or supplied primarily with rainwater: a rainfed lake. 2. Of or relating to farming that relies on natural rainfall rather than irrigation: rainfed crop production.

Which is rainfed crop?

Rainfed agriculture includes both permanent crops (such as rubber, tea, and coffee) as well as annual crops (such as wheat, maize, and rice). In temperate regions with relatively reliable rainfall and good soils, rainfed agriculture generates high yields. Supplemental irrigation practices boost yields even higher.

What is irrigated and rainfed?

The most widespread system is rainfed, which depends basically on atmospheric precipitation. Apart from the rainfed crop, there are irrigated crops that take advantage of the water from the atmospheric precipitations and the land is also irrigated. The irrigated farms are very different from those of rainfed crops.

Which crop is most suitable for rainfed areas?

About 60% of the rainfed areas are used for growing winter season crops like wheat, barley, gram, lentils, rapeseed, and canola mustard while among the important summer crops; millet, sorghum, maize, pulses, guar, groundnut, and watermelon are planted on nearly 40 percent of rainfed lands.

What are the main problem of rainfed farming?

Rainfed Crops are prone to breaks in the monsoon during the crop growth due to water stress. This water stress may be due to variability of rainfall, delay in sowing, diversity in crop management practice and variability of the soil type. The prolonged breaks can result in partial o r complete failure of the crops.

Is Rice a rainfed crop?

Rice is one of the major crops grown and consumed in rainfed areas, and rainfed cultivation accounts for about 25% of global rice production. Due to its dependence on climate, rainfed rice cultivation is vulnerable to changes in temperature and rainfall.

Which crop is called as miracle crop?

Soybeans
Soybeans have long been called the miracle crop for good reason. As the world’s top provider of protein and oil, the crop is the darling of groups as diverse as dieticians and livestock feeders.

Which country has highest irrigated area?

China
China is the top country by total area equipped for irrigation in the world.

Why Maize is called miracle crop?

Maize is one of the most important cereal crops in the world agricultural economy both as food for man and feed for animals. It is a miracle crop. It has very high yield potential, there is no cereal on the earth which has so immense potentiality and that is why it is called queen of cereals.

Why is soybean called miracle crop?

Soybeans are sometimes called the “miracle crop” because of their hundreds of uses. Each person eats 35 to 40 pounds of soybeans a year. People may eat soybeans in bread, cereal, snacks, or salad dressing. During the Civil War, soybeans were used in place of coffee because real coffee was scarce.

Which country has best canal system?

Indus Basin of Pakistan Pakistan is an agricultural country and its agriculture depends on irrigation. The irrigation system of Pakistan is the world’s largest irrigation source. It provides water to about 18 million hectares of arable land.

Which country is the most irrigated?

China is the top country by total area equipped for irrigation in the world. As of 2018, total area equipped for irrigation in China was 74,160 thousand hectares that accounts for 21.87% of the world’s total area equipped for irrigation.

Rainfed agriculture includes both permanent crops (such as rubber, tea, and coffee) as well as annual crops (such as wheat, maize, and rice). For example, tubers, a staple crop for sub-Saharan Africa, have been all but uninfluenced by the technological developments of the green revolution.

Which country is rank first in rainfed agriculture?

Abstract: India ranks first among the rainfed agricultural countries in the world.

What is the meaning of the word rainfed?

Filled or supplied primarily with rainwater. A rainfed lake. Of or relating to farming that relies on natural rainfall rather than irrigation. Rainfed crop production.

What are the different types of rainfed agriculture?

What is Rainfed Agriculture? Definition: Dryland Agriculture refers to the growing of crops entirely under rainfed conditions. Based on the amount of rainfall received, dryland agriculture (Rainfed Agriculture)can be grouped into three categories: 1. Dry Farming:

Where does rainfed agriculture take place in the world?

It provides much of the food consumed by poor communities in developing countries. For example, rainfed agriculture accounts for more than 95% of farmed land in sub-Saharan Africa, 90% in Latin America, 75% in the Near East and North Africa, 65% in East Asia, and 60% in South Asia. There is a correlation between poverty, hunger, and water stress.

How are yields increased in a rainfed system?

Yields can be increased by improved management of rainwater in rainfed systems which presently generates excessive runoff and causes soil erosion Investments to maximize rainfall infiltration and the water-holding capacity of soils minimize land degradation while increasing the water available in the soil for crop growth.

Filled or supplied primarily with rainwater. A rainfed lake. Of or relating to farming that relies on natural rainfall rather than irrigation. Rainfed crop production.

How much of the World’s cropped area is rainfed?

Rainfed agriculture accounts for more than 75% of the cropped area in the world. One-third of the developing world’s population lives in the less-favored rainfed regions [1]. In India, rainfed agriculture accounts for 60% of the cropped area, and is the food basket for the poor, with a millet-dominant crop pattern.
