Question

fertilisers to the soil, which crop should be
grown in the fields for fulfilling the
requirement of nitrogen? *
O
Peas
O Barley
O Wheat
O Rice​

Answer 1

Answer:

Barley

Explanation:

Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.

Answer 2

Answer:

Peas

Explanation:

I am not sure its peas. I am writing this answer because certain microbes such as Rhizobium can convert atmospheric nitrogen into a form that can be easily used by plants. This bacterium gets associated with the roots of leguminous plants such as peas, beans and gram. The plant provide food and shelter to the bacterium. Rhizobium fixes nitrogen for the plant and helps in replenishing the soil. That is why farmers grow a leguminous plant in between two main crops to maintain the fertility of the soil.
