Observe the graph and answer the following question. Why farmers cultivate Wheat crop only in Rabi season?

The crops that are grown only in winter (October to March/April) are called "Rabi crops". These are also known as non-monsoon crops. These crops require a warm climate for seed germination and cold climate to grow. Since wheat is suitable to grow in temperate climate i.e., in a warm climate, Rabi season is the best season to cultivate it.

Observe the graph and answer the following question. What happens if wheat is cultivated in the month of September?

Wheat is a Rabi crop which is grown in winter between October and March/April. Rabi crops are also known as summer season crops. Wheat is a short night duration plant and it requires less water, warm/hot climate and humidity to grow. We get hot climate from February onwards and it is suitable for maturing grains. Short night duration and suitable temperature are needed for proper flowering in wheat plants. That is the reason wheat is cultivated in the Rabi season only. Therefore, if wheat is sown in the month of September, there will be less yield and loss in productivity.

Observe the graph and answer the following question. Why do farmers not cultivate Wheat in Kharif season?

Rabi crops are grown in winter between October and March/April, whereas Kharif crops are grown in the rainy season. Rabi crops are also known as summer season crops and wheat is an example. Wheat is a short night duration plant and it requires less water, warm/hot climate and humidity to grow. We get hot climate from February onwards and it is suitable for maturing grains. Short night duration and suitable temperature are needed for proper flowering in wheat plants. That is the reason wheat is cultivated in the Rabi season only and not in Kharif season.

Observe the graph and answer the following question. If we cultivate wheat in the month of November what will happen?

Wheat is a Rabi crop which is grown in winter between October and January/April. These are also known as non-monsoon crops. Wheat is a short night duration plant and it requires less water, warm/hot climate and humidity to grow. If we cultivate wheat crops in the month of November, then these crops will get appropriate climatic conditions like low humidity and temperature around 10 0 C to 15 0 C and there will be good the yield and productivity of crops.

Observe the graph and answer the following question. Heat is essential for ripening and development of grains in the plants. Then when do we get more heat?

Plants require proper water, minerals and temperature to grow. Heat is required for ripening and development of grains in the plants. For e.g., wheat plants. We get hot climate from February onwards and it is suitable for maturing wheat grains. Short night duration and suitable temperature are needed for proper flowering in plants. So, we get more heat in summer i.e., February onwards.
