1.
Origin of paddy ?
Correct Answer
B. China
Explanation
Paddy, also known as rice, is believed to have originated in China. Archaeological evidence suggests that rice cultivation began in the Yangtze River valley around 10,000 years ago. From there, it spread to other parts of Asia, including India and Southeast Asia. China has a long history of rice cultivation and is known for its diverse varieties of rice. Therefore, it is logical to conclude that China is the origin of paddy.
2.
Sowing time of paddy in south zone ( dakshina mandalam) during kharif
Correct Answer
C. September
Explanation
The correct answer is September because during the kharif season in the south zone (dakshina mandalam), paddy is typically sown in September. This is because September is the time when the monsoon rains are well-established, providing the necessary water for paddy cultivation. Sowing paddy in September ensures that the crop gets enough moisture for germination and growth, leading to a successful harvest.
3.
Period of short duration varieties
Correct Answer
C. 110-120 days
Explanation
The period of short duration varieties refers to the time it takes for these varieties of crops to mature and be ready for harvest. In this case, the correct answer is 110-120 days, which means that these particular varieties take between 110 and 120 days to reach maturity.
4.
Prevention of Cyprus rotendus
Correct Answer
B. Butachlor
Explanation
Butachlor is a herbicide that is commonly used for the prevention and control of weeds, including Cyprus rotendus. It is effective in inhibiting the growth of weeds by interfering with their cellular processes, ultimately leading to their death. By using Butachlor, farmers can effectively prevent the growth and spread of Cyprus rotendus, ensuring the health and productivity of their crops.
5.

The state also has a long tradition of rice cultivation and farmers in West Bengal have adopted advanced farming techniques and technologies. Additionally, the government of West Bengal has implemented various agricultural policies and schemes to support and promote paddy cultivation in the state. These factors contribute to West Bengal's high production of paddy compared to other states like Tamil Nadu, Andhra Pradesh, and Uttar Pradesh.
6.
Seed quantity of SRI ?
Correct Answer
B. 2kg/acre
Explanation
The correct answer is 2kg/acre. This suggests that the recommended seed quantity for the SRI (System of Rice Intensification) method is 2 kilograms per acre of land. This information is important for farmers who are practicing SRI as it helps them determine the appropriate amount of seeds to use for optimal crop growth and yield.
7.
SRI started in
Correct Answer
D. Madagascar
Explanation
The correct answer is Madagascar because the question asks where SRI started, and out of the given options, Madagascar is the only country mentioned. Therefore, it can be inferred that SRI started in Madagascar.
8.
Plant population per sq. M In kharif
Correct Answer
A. 33
Explanation
The given data represents the plant population per square meter in the kharif season. The correct answer is 33, which indicates that there are 33 plants per square meter in the kharif season.
9.
To overcome zinc deficiency
Correct Answer
A. 2g zinc sulpHate
Explanation
The correct answer is 2g zinc sulphate. Zinc sulphate is a commonly used supplement to overcome zinc deficiency in the body. It is easily absorbed by the body and helps in various physiological processes such as immune function, wound healing, and DNA synthesis. Zinc sulphate is available in different forms, including tablets, capsules, and liquid, making it convenient for consumption. Additionally, it is relatively safe and well-tolerated when taken in recommended doses.
10.
Moisture % in paddy for harvest
Correct Answer
A. 20-22%
Explanation
The moisture percentage in paddy for harvest should ideally be between 20-22%. This range ensures that the paddy is sufficiently dry and can be stored without the risk of spoilage or mold growth. If the moisture content is too high, it can lead to quality deterioration and the growth of microorganisms. On the other hand, if the moisture content is too low, it can result in excessive drying and brittleness of the grains. Therefore, maintaining a moisture level of 20-22% is crucial for proper paddy harvest.
11.
Moisture % in paddy for storage
Correct Answer
B. 14%
Explanation
The correct answer is 14% because paddy, which is rice that still has its husk, needs to be dried to a moisture content of around 14% before it can be stored. This moisture level is considered optimal for preventing the growth of mold and fungi, which can spoil the rice during storage. If the moisture content is too high, it can lead to the rice becoming damp and prone to spoilage. Conversely, if the moisture content is too low, the rice can become brittle and lose its quality. Therefore, maintaining a moisture content of 14% is crucial for proper storage of paddy.
12.
Inputs used for harvest of paddy
Correct Answer
A. Serrated sickles
Explanation
Serrated sickles are used for the harvest of paddy. Paddy refers to the rice plant that is grown in flooded fields. Serrated sickles have a jagged edge that helps in cutting through the paddy plants efficiently. The jagged edge allows for a clean and precise cut, ensuring that the paddy plants are harvested effectively. Other tools like ploughs and harrows may be used for preparing the fields or tilling the soil, but when it comes to the actual harvest of paddy, serrated sickles are the most suitable tool.
13.
Seed quantity in aerobic rice method
Correct Answer
D. 25 to 30kg
Explanation
The correct answer is 25 to 30kg. This is because in the aerobic rice method, which involves growing rice in non-flooded conditions, a higher seed quantity is required compared to traditional flooded rice cultivation. This is because the seeds need to be sown at a higher density to compensate for the lack of water and ensure optimal growth and yield. Therefore, a higher seed quantity of 25 to 30kg is recommended for the aerobic rice method.
14.
Example of short grain varieties
Correct Answer
C. Japonica
Explanation
The correct answer is Japonica because it is the only option that fits the category of "short grain varieties". Basmati and Para boiled are types of rice, but they are classified as long grain varieties. Gleutius is not a recognized variety of rice. Japonica, on the other hand, is a type of short grain rice commonly grown in Japan and other parts of Asia.
15.
Nitrogen required for aerobic rice method
Correct Answer
D. 120kg
Explanation
The correct answer is 120kg. This is because the aerobic rice method requires a higher amount of nitrogen compared to traditional rice cultivation methods. Nitrogen is an essential nutrient for plant growth, and in aerobic rice cultivation, where the rice plants are grown in well-drained soil with sufficient oxygen supply, the higher nitrogen requirement is necessary to support the increased growth and yield potential of the plants. Therefore, 120kg of nitrogen would be required for the aerobic rice method.
16.
Mostly exported varieties from ind,pak
Correct Answer
A. Basmati
Explanation
Basmati is the correct answer because it is a type of rice that is mostly exported from India and Pakistan. Basmati rice is known for its long, slender grains and aromatic flavor. It is highly sought after in many countries and is often used in various cuisines around the world.
17.
One basta =------kg
Correct Answer
B. 75
18.
Which chemical is used for removing seed dormancy
Correct Answer
B. Nitric acid
Explanation
Nitric acid is used for removing seed dormancy. It is a strong acid that can break down the hard seed coat and promote germination. By treating seeds with nitric acid, the dormancy mechanisms are disrupted, allowing the seeds to sprout and grow. Carbondezim and Imidachloprid are not commonly used for removing seed dormancy, making Nitric acid the correct answer.
19.
Mostly used paddy transplantation methods
Correct Answer
A. Zig zag
Explanation
The correct answer is Zig zag. Zig zag is one of the most commonly used methods for paddy transplantation. In this method, the rice seedlings are transplanted in a zig zag pattern in the field. This pattern allows for better spacing between the seedlings, which ensures proper growth and development of the plants. It also helps in efficient water and nutrient management, as well as reducing weed growth. Overall, the zig zag method is preferred by farmers for its simplicity and effectiveness in maximizing rice yields.
20.
