The correct answer is (b).
Gypsum is a mineral that is used as a fertilizer to improve soil structure and fertility. It is especially beneficial for crops that are sensitive to low levels of calcium, such as berseem. Berseem is a legume that is grown for its forage and hay. It is a high-quality feed for livestock and is also used in the production of silage. Berseem is a sensitive crop and requires a lot of nutrients, including calcium. Gypsum can help to improve the soil’s ability to hold onto calcium, which is essential for berseem’s growth.
The other options are incorrect because they are not crops that are sensitive to low levels of calcium. Paddy is a type of rice that is grown in flooded fields. Wheat is a cereal grain that is grown in temperate climates. Groundnut is a legume that is grown for its oil and nuts. These crops do not require as much calcium as berseem, so gypsum is not as necessary for their growth.
In conclusion, the correct answer to the question “Application of gypsum is required more in the crop of” is (b). Berseem is a crop that is sensitive to low levels of calcium, so gypsum can help to improve its growth.
