How many catties can an acre of rice in India yield on average? Compared with China, how much is the difference between the yield per mu?

author:Muhai

India is the world's second largest rice producer and the largest country is China, with the total rice production of both countries exceeding the 100 million tons mark. Since 1980, India's rice production has been increasing, from 53.6 million tons to 120 million tons in fiscal years 2020-2021, ranking first in the world in terms of planting area.

As one of the three staple foods, the importance of rice is self-evident, and rice production is related to the feeding of 3.5 billion people. In terms of total output, India is the only country that can be "compared" with the mainland, and its rice production capacity has naturally attracted much attention. So, how many catties of rice per mu can be produced in China and India? How big is the yield gap per acre?

What are the advantages of rice production in India? How many catties can be produced per mu?

India is one of the four ancient civilizations, with a long history of agricultural civilization and a long history of rice cultivation. The october 29, 2014 report published in Nature pointed out that the Ganges Valley in northern India, the Yangtze River Basin in China, and the southern slopes of the Himalayas are the birthplaces of rice.

In addition to its deep historical heritage, India's rice production has unique advantages. Rice is suitable for living in humid, hot climates, while India's Ganges Valley is an extraordinary endowment, with abundant heat, with an average annual rainfall of 760 to 2286 mm, and rain and high temperatures create an ideal humid and hot environment.

The distribution of rice in India is also very distinctive, mainly concentrated in the eastern plains with abundant water sources, as well as the southern plateau and the western coast, covering almost all the deltas, the Assam plain and the low mountains and hills. Due to its tropical and subtropical location, india is hot and humid throughout the country, with rice ripening two or three times a year in the east and south, and one ripening a year in the north and west. From the perspective of harvest cycle, Indian rice has more production advantages than mainland rice.

It is worth mentioning that the area under rice cultivation in India has remained high, and the total output is also considerable. In 2015, India's rice cultivation area reached 43.86 million hectares, which decreased in 2020, but also exceeded 40 million hectares. On the mainland, the area under rice cultivation from 2015 to 2021 showed a downward trend, from 30.78 million hectares to 29.92 million hectares. Therefore, India's rice planting area also has obvious advantages.

But in terms of yield, India's rice performance is mediocre, below the global average. According to statistics, from 1991 to 2020, the average yield of rice per mu in India increased from 232 catties to 362 catties, and the yield increased by 130 catties in 30 years. From 2016 to 2021, the yield per mu tended to be stable, but it always hovered at a low level of 320 to 370 jin, and the interannual increase was minimal.

Many people may be skeptical: the yield of more than three hundred catties per mu is really unbelievable! In China, more than 300 jin / mu can only be regarded as low-yield rice, even the worst planting conditions of seawater rice in the mainland, the average national yield has reached 900 kg (2021), the highest appeared in the record of 1720 kg, a fraction alone is twice as high as the average yield per mu in India!

Why is the yield of rice in India so low?

It is undeniable that India has a vast area of rice planting, large-scale planting area, can be harvested 1 to 3 times a year, it is reasonable to say that the yield should not be so inferior. But this is indeed the case, why?

First, India's rain and heat resource allocation is not uniform. The summer winds of the Indian Peninsula are the southwest monsoon, and monsoon rains are the main source of water for more than 20 million rainy rice feeders. However, the seasonal movement of the air pressure belt and the wind belt has led to uncertain timing of the southwest monsoon landing, which is not conducive to rice production sooner or later.

When the southwest monsoon lands prematurely and retreats late, it is easy to cause flood disasters, which is not conducive to rice growth. When there is too much rainfall, the water level of the paddy field is deep, the soil is oxygen-deficient, the metabolism of rice roots is blocked, the fertilizer absorption ability is weakened, and the growth of rice is insufficient. When the southwest monsoon lands too late and the retreat is advanced, it is easy to cause rice field drought and high temperature heat damage, the pollination and grouting of rice is easily affected, the fruiting rate is reduced, and the empty grain rate is increased, which also affects the harvest.

Second, India's arable land, although vast, is not of the highest quality. The plains in India account for about 40%, the mountainous areas account for about 25%, the plateau accounts for about 33%, the plateau mountains are dominated by semi-arid areas, the annual evaporation is large, and rice production needs irrigation. According to statistics, the area of irrigated rice in India is about 22 million hectares, and the irrigation rate is difficult to guarantee. The Western Desert is an arid region that also suffers from water scarcity and lackluster land quality.

The Indus Valley, which has the most abundant water sources, often floods, and crops are immersed in a state of immersion for a long time, not only can not fertilize, but also lead to a large loss of soil fertility and poor fertilizer retention.

In short, India's land conditions and natural climate have limiting factors, and the yield of rice is difficult to reach 1,000 to 2,000 catties per mu like China. Comprehensive land, water, heat and other conditions, the more ideal is only the Punjab region, which is located in northwest India, located on the edge of the desert, the climate is arid, but it is also the confluence of India's 5 major rivers, irrigation water is stable and sufficient, light and heat conditions are similar to the mainland's Xinjiang, is a veritable "Indian granary".

According to the Punjab Ministry of Agriculture, the average yield of rice in the state was 6 tons per hectare (800 catties per mu) in 2019 and 6.9 tons per hectare (920 catties per mu) in 2020, which is a first-class level in India. Of course, compared with the mainland, this yield is decent and not too eye-catching.

How many catties can an average of one mu of rice on the mainland produce?

Like India, the mainland is also the world's largest producer of rice, but the total yield and yield per mu are significantly higher.

According to the statistics of the National Bureau of Statistics, the total area of rice planted on the mainland in 2021 was 29.921 million hectares, and the total output reached 212.8 million tons, with an average yield of 7113.4 kg of grain per hectare, an increase of 1.04% year-on-year. The yield per mu is 948.4 catties, which is more than twice the average yield of India.

The figure of 950 catties is the national average and represents the overall level of rice production in the country. In recent years, the yield of rice on the mainland has been quite stable, for example: the average yield per mu in 2020 is 939.2 catties, in 2019 it is 941.2 catties, and in 2018 it is 936.9 catties, all in the range of 930 to 950 catties.

Although the mainland rice production is strong, it has not won the high-yield competition, and the United States and Australia have higher yields than the mainland. Taking the data of 2020 as an example, the yield of rice per mu in the mainland is about 940 jin, while the mu yield in Australia has reached an exaggerated 1337 jin, followed by the United States, reaching 1138 jin, and the average mu yield has exceeded 1000 jin.

Overall, the mainland's rice yield is still at the forefront of the world, and the advantages of total rice production are particularly prominent, and countries such as the United States and Australia are out of reach (the mainland accounts for 37% of the world).

I believe that everyone must have a question: why can the mainland's rice achieve high and stable yields?

First of all, looking at natural factors, the continent is vast, the plain area accounts for 12% of the total area, the basin accounts for 19%, the hilly accounts for 10%, and the rice cultivation area is vast. Affected by summer winds, the mainland rice production rain and heat at the same time, sufficient water sources, convenient irrigation, deep and fertile soil layer, the advantages at a glance.

The second is the technical advantage, the mainland rice planting has a long history, rich experience, Hubei, Heilongjiang, Xinjiang and other provinces and regions according to local conditions, the introduction of supporting high-yield cultivation technology, to ensure the steady increase in grain output. For dwarf rice varieties, mainland experts in the last century summed up the "three yellows and three blacks" high-yield technology, to promote strong stalks, long ears, the number of dwarf ear ears per hectare up to 306 ~ 3.36 million ears, the number of grains per panicle 76 ~ 104 grains, the yield per mu up to 912 pounds, an increase of 157% over the national yield in the same period, the effectiveness of the application of technology is clear at a glance.

Finally, there is the advantage of varieties, and the rice in the mainland has both characteristic varieties and high-yield varieties with "thousand grain weight" as the breeding index. Rice breeders combined hybrid advantages with plant type improvement to produce indica-type super hybrid rice, which greatly increased yields. Compared with ordinary rice, hybrid rice has more large ears, the total biomass is increased by an average of 10.6%, the jointing is 1.3% ahead, and the yield at the panicle-maturity stage is increased by 19.9%, and the effect is remarkable.

summary

The natural climate, land conditions and continental conditions of rice in India are different, and there are also differences in planting techniques and varieties, and the yield per mu varies greatly.

At present, the yield of rice per mu in India is stable at about 320 to 370 catties, while the mainland is 930 to 950 catties, a difference of 2 to 3 times between the two countries. What do you think about that? Feel free to leave a message in the comments section.
