The Village is about 10 km from Gudha gorji, 40 km from Jhunjhunu and 150 km from Jaipur.  Bhojgarh was founded by Thakur Gopal Singh Shekhawat.  Number of its residents serves in Indian Army, Indian Airforce and Paramilitary Forces.  However, the farming is the main occupation for the most of Bhojgarh residents.  The main crops in the monsoon seasons are Bajara (Pearl Millet), Moth, and Guar.  The main crops in the winter months are Wheat, Barley, Sarson ( Mustard seed), and Chana.

Mustard plant: Mustard plants are any of several plant species in the genera "Brassica" and "Sinapis" in the family Brassicaceae.  Mustard seed is used as a spice.  Grinding and mixing the seeds with water, vinegar, or other liquids, creates the yellow condiment known as prepared mustard.  The seeds can also be pressed to make mustard oil, and the edible leaves can be eaten as mustard greens.

Dundlod: Dundlod (Hindi: ) (Rajasthani: डळौद ) is a town in Jhunjhunu district of Rajasthan in India.  It is situated in the Shekhawati region of Rajasthan.  It is famous for its fort and havelis.  It extends between latitude 28°.06’ in the north and longitude 75°.20’ in the east.  It lies about seven kilometers north of Nawalgarh in the heart of the Shekhawati region.

Garden cress oil: Garden cress oil is obtained from garden cress ("Lepidium sativum L") seeds, by cold pressing (hydraulic pressing), solvent extraction (soxhlet) and supercritical CO.  The total oil content of garden cress seeds is 21.54% (by solvent extraction method) garden cress oil has a typical smell of mustard oil but less pungent than mustard oil.

Mustard oil: The term mustard oil is used for two different oils that are made from mustard seeds:

Jakhal: Jakhal is a village in the Shekhawati region of Rajasthan, India.  It is located in the district of Jhunjhunu, approximately 20 km east of Nawalgarh and 30 km south of Jhunjhunu.  Jakhal was founded by Salehadi Singh Shekhawat on August 9, 1732 (teej of Sravana Shukla 1789).  Hundreds of its residents serve in Indian Army.  However, the farming is the main occupation for the most of Jakhal residents.  The main crops in the monsoon seasons are Bajara (Pearl Millet), Moth, and Guar.  The main crops in the winter months are Wheat, Barley, Sarson (Mustard oil, Mustard seed), and Chana (Chickpeas).

Mustard seed: Mustard seeds are the small round seeds of various mustard plants.  The seeds are usually about 1 to in diameter and may be colored from yellowish white to black.  They are important spice in many regional foods and may come from one of three different plants: black mustard ("Brassica nigra"), brown Indian mustard ("B. juncea"), or white mustard ("B. hirta/Sinapis alba").

Sinigrin: Sinigrin is a glucosinolate that belongs to the family of glucosides found in some plants of the Brassicaceae family such as Brussels sprouts, broccoli, and the seeds of black mustard ("Brassica nigra").  Whenever sinigrin-containing plant tissue is crushed or otherwise damaged, the enzyme myrosinase degrades sinigrin to a mustard oil (allyl isothiocyanate), which is responsible for the pungent taste of mustard and horseradish.  Seeds of white mustard, "Sinapis alba", will give a much less pungent mustard because this species contains a different glucosinolate, sinalbin.

1998 Delhi oil poisoning: In 1998, adulterated mustard oil poisoning in Delhi resulted in widespread dropsy and deaths of 60 people and illness of more than 3000.  It was revealed that white oil, a petroleum product was mixed with edible mustard oil.  Sale of mustard in loose quantity was banned by a court order, to prevent more health hazards.  In September 1998, the ban on packed mustard oil was removed after a Cabinet decision with a condition that the date of packing should be prominently displayed.  Even though mustard oil is banned as an edible oil in countries like USA, Canada and EU due its erucic acid content, the oil is widely used as an edible oil in North India, Pakistan and Nepal.

Mustard oil bomb: The mustard oil bomb is a chemical herbivory defense system found in members of the Brassicaceae (or cabbage family).  The mustard oil bomb requires the activation of a common plant secondary metabolite, glucosinolate, by an enzyme, myrosinase.  The defense complex is typical among plant defenses to herbivory in that the two molecules are stored in different compartments in the leaves of plants until the leaf is torn by an herbivore.  The glucosinolate has a β-glucose and a sulfated oxime.  The myrosinase removes the β-glucose to form mustard oils that are toxic to herbivores.  The defense system was named a "bomb" by Matile, because it like a real bomb is waiting to detonate upon disturbance of the plant tissue.
