Agricultural Practices and Land Use

Animal husbandry is the branch of agriculture concerned with the care, breeding, and management of livestock.

The Green Revolution refers to a set of research technology transfer initiatives occurring between the 1930s and the late 1960s that greatly increased agricultural production worldwide, particularly in developing nations, through high-yielding crop varieties and modern farming techniques.

The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) led a successful watershed management project in Kothapally village. This initiative educated and helped the villagers implement sustainable agricultural and water-conservation practices.

The Green Revolution refers to a period of technological transfer in agriculture that began in the mid-20th century. It promoted modern methods such as high-yielding variety seeds, chemical fertilizers, pesticides, and advanced irrigation systems to increase crop yields.

Agribusiness refers to large-scale, commercial farming operations that are run like modern businesses, focusing on maximizing efficiency and profit. This contrasts with subsistence farming, which is done mainly to feed the farmer's family.

Organic farming relies on natural inputs like manure, compost, and biological pest control rather than synthetic chemicals and artificial fertilizers. This approach aims to maintain soil health and ecological balance. Farming with heavy chemical use or high electricity consumption represents conventional or industrial agricultural practices.

Slash and burn agriculture, widely known as Jhum cultivation in northeastern India, is a traditional farming method where forests are cleared and burned to create fertile ash-enriched fields. After a few years of cultivation, the land is left fallow to regenerate while farmers move to a new patch of forest.

The Green Revolution focused on modern agricultural techniques such as mechanized farming, high-yielding hybrid seeds, and monoculture to increase crop yields. Slash and burn is an ancient, traditional form of shifting cultivation that is not a characteristic of the Green Revolution.

Domestication involves breeding plants and animals over generations to highlight traits that are beneficial to humans, such as docility in animals or higher yields in crops. This process was a cornerstone of the agricultural revolution, enabling permanent human settlements.

Fertile soil is essential for successful farming because it contains the necessary nutrients for crops to grow healthy and strong. Unreliable water or excessive flooding can damage crops and lead to poor harvests.

FCR stands for Food (or Feed) Conversion Ratio, which measures how efficiently an animal converts feed into body mass. Option A correctly identifies this term, whereas 'ration' refers to the daily feed allowance itself.

Concentrates are animal feeds that are highly digestible and nutrient-dense. They are characterized by having low fiber and water content, but high energy value, making them ideal for supplementing the diets of high-producing animals.

Organic farming is defined by the avoidance of synthetic chemicals, pesticides, and fertilizers in the production of food.

Monocultures lack genetic diversity, meaning that if a specific pest or disease evolves to attack that crop, it can spread rapidly through the entire field without resistance.

Leaving crop residue on the field protects the soil surface from wind and water, which significantly reduces soil erosion.
