The Jobner research station of Jaipur has developed the Jadia and Jwala varieties of moth bean. It is a drought-resistant crop that can be easily cultivated in the hot and dry habitats of the northern and western parts of our country. It is grown on an area of 13.19 lakh hectares with a production of 17.53 lakh tonnes.

Based on chemical, physical and biological features, the soil has been categorized into 12 categories, which are called soil orders. These are Vertisols, spodosols, Mollisols, histosols, Entisols, Andisols, Ultisols, Oxisols, Inceptisols, Gelisols, Ardisols, Alfisols. Entisols are the pedologically youngest of the soils added to the order recently. It is formed from freshly deposited materials.

In India, Dr. Arun Krishnsan and Dr. Hiralal Chaudhari launched the Blue Revolution, also known as the Nili Kranti Mission in India, between 1985 and 1990.

The rotation intensity of any cropping pattern means a growing combination of crops that matches climatic conditions, water availability, and nutrient storage of soil in that particular field. This is calculated by counting the number of crops grown in a rotation and is multiplied by 100 and then divided by the duration of the rotation. Therefore here the intensity is 300%.

Mechanical analysis is the determination of the size range of particles present in the soil and it is expressed as a percentage of the total dry weight. And its analysis is based on Stroke's law, which states that the terminal velocity of settling of spherical particles in suspension varies with the square of the diameter of the sphere, the density and viscosity of the field and the density of the sphere (soil particles are considered as spheres).

Lucerne, also known as Alfalfa, whose scientific name is Medicago sativa, is a perennial flowering plant in the legume family. It is native to Persia but is now grown worldwide as an important forage crop. It is used for grazing, hay and silage, as well as green manure and cover crops.
