Rain-fed Agriculture: A Vital Lifeline in a Changing Climate Rain-fed agriculture, the practice of cultivating crops solely reliant on rainfall for water, sustains a significant portion of the global population. It plays a crucial role in food security, particularly in developing countries where access to irrigation is limited. However, this system faces increasing challenges due … Read more
SEED Industry India is the fifth largest seed market across the globe. It is expected to grow at more than 15% during 2017–2022, and can reach a value of more than US$ 7 Billion by 2022. The seed market is majorly contributed by non-vegetable seeds such as corn, Cotton, paddy, wheat, sorghum, sunflower and Millets. … Read more
Water use efficiency in relation to crop production Land and water scarcity are major constraints to the production of food required to meet the quantitative and qualitative shifts of the world’s demand in the mid-twenty-first century. Whereas land and water availability are constrained on a global scale, there are important regional and crop-specific differences that … Read more
Techniques of Irrigation and Soil conservations and soil Health cards Techniques of irrigation Surface Irrigation In this method water flows and spreads over the surface of the land. Varied quantities of water are allowed on the fields at different times. Hence, flow of water under surface irrigation comes under unsteady flow. As a result it … Read more
The Green Revolution was a period of agricultural development that began in the mid-20th century and focused on increasing crop yields through the use of new technologies, such as high-yield varieties of crops, fertilizers, and pesticides. The Green Revolution was a major success, and it helped to increase food production around the world. However, it … Read more
What is Furrow Irrigation? Furrow irrigation is a method of irrigation in which water is applied to the SoilSoil in long, narrow channels called furrows. The furrows are usually made by plowing or disking the Soil, and they are spaced according to the crop being grown and the amount of water available. The water is … Read more
The Green Revolution was initiated in the 1960’s to address the issue of Malnutrition in the developing world.

Electrostatic The basic principle of Electrostatics is based on the fact the electric charges attract or repel other charges depending on their relative signs and the law of force is given by Coulomb‘s law. Coulomb’s law states that: The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the … Read more
