Question

In which type of cotton production, fertilizers are not used?

• A. Bt
• B. Cyano ethylated
• C. Organic
• D. Carboxy methylated

Hint:

Remember the differences between Organic and Bt Cotton: \[ \begin{array}{|c|c|c|} \hline \textbf{Feature} & \textbf{Organic Cotton} & \textbf{Bt Cotton} \hline Synthetic Fertilizers & \textbf{Not Used} & Used \hline Synthetic Pesticides & Avoided & May be Used \hline Genetically Modified & No & Yes \hline Eco-friendly & High & Moderate \hline \end{array} \] A simple memory trick is: \[ \boxed{ \text{Organic Cotton} \Longrightarrow \text{Natural Farming} \Longrightarrow \text{No Synthetic Fertilizers} } \] This distinction is frequently asked in textile technology, agriculture, and environmental science examinations.

Answer 1

The Correct Option is C

Concept: Cotton can be cultivated using different agricultural practices depending on the farming system adopted. The major types of cotton production include:
• Conventional Cotton
• Bt Cotton
• Organic Cotton Among these, Organic Cotton is produced without the use of synthetic chemical fertilizers, pesticides, herbicides, or genetically modified seeds. Instead, it relies on natural farming practices to maintain soil fertility and crop health. Organic cotton cultivation aims to protect the environment, conserve biodiversity, and produce eco-friendly textile fibres.

Step 1: Understand Organic Cotton production.
Organic cotton is grown by following certified organic farming practices. In this method, \[ \boxed{ \text{Synthetic chemical fertilizers are not used.} } \] Instead, farmers use natural alternatives such as \[ \begin{aligned} &\bullet\ \text{Farmyard manure (FYM),} &\bullet\ \text{Compost,} &\bullet\ \text{Green manure,} &\bullet\ \text{Biofertilizers,} &\bullet\ \text{Vermicompost.} \end{aligned} \] These practices improve soil fertility naturally while reducing environmental pollution.

Step 2: Examine each option.
Option (A): Bt Cotton Bt cotton is a genetically modified cotton variety developed for insect resistance. Although it reduces insecticide use, fertilizers are still applied during cultivation. \[ \boxed{\text{Incorrect}} \] Option (B): Cyano ethylated Cyano ethylation is a chemical modification process of cellulose and is unrelated to cotton cultivation. \[ \boxed{\text{Incorrect}} \] Option (C): Organic Cotton Organic cotton is cultivated without synthetic chemical fertilizers and pesticides. It follows environmentally sustainable farming practices. \[ \boxed{\text{Correct}} \] Option (D): Carboxy methylated Carboxymethylation is a chemical treatment of cellulose and has no relation to cotton production methods. \[ \boxed{\text{Incorrect}} \]

Step 3: Write the final answer.
Thus, the type of cotton production in which synthetic fertilizers are not used is \[ \boxed{\text{Organic Cotton}.} \] Therefore, \[ \boxed{\text{Option (C) is the correct answer.}} \]
