Explanation

• Stratification is the process of exposing seeds to low temperature before germination to break dormancy.
• It helps seeds of temperate plants to germinate in the next growing season.

Additional information:

• Vernalization (different) is low temperature exposure for plants, not seeds.
• Scarification involves breaking seed coat to allow water absorption.

Explanation

• Cotton requires critical irrigation during flowering and boll formation to ensure good yield and fiber quality.
• Water stress at these stages can reduce boll size and number, affecting total production.

Additional information:

• Flowering stage: Ensures healthy flower development
• Boll formation stage: Supports fruiting bodies (bolls) growth

Explanation

• Denitrification is the loss of nitrogen as gases (N₂ or N₂O) from the soil.
• Occurs more in clayey soils due to poor drainage and waterlogging.
• Reduces soil fertility and crop yield.

Explanation

• Leguminous plants form a symbiotic relationship with Rhizobium bacteria.
• These bacteria fix atmospheric nitrogen (N₂) into usable forms.
• This process improves soil fertility naturally.
• On average, nitrogen fixation by legumes adds about 210 kg nitrogen per hectare.
• Reduces the need for chemical nitrogen fertilizers.
