NEET BIOLOGY

Detailed explanation-1: -Nitrogen (N) deficiency appears as a general pale yellowish-green plant with slow growth and reduced tiller development. If the deficiency persists, plants remain pale green, have reduced growth, and the stand appears thin.

Detailed explanation-2: -Sulphur. Sulphur is a component in the formation of chlorophyll. Deficiencies result in yellow leaves and stunted growth.

Detailed explanation-3: -Nitrate deficiency Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant’s ability to photosynthesise and grow properly, which reduces the farmers’ crop yield .

Detailed explanation-4: -Nitrogen deficiency is a deficiency of nitrogen in plants. This can occur when organic matter with high carbon content, such as sawdust, is added to soil. Soil organisms use any nitrogen available to break down carbon sources, making nitrogen unavailable to plants.
