The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others. Without these activities, a crop cannot be grown.
There was an increase in global production of primary crops by 56% between 2000 and 2022 to 9.6 billion tonnes, which represents a 0.7% compared to 2021. [2] This represents 3.5 billion tonnes more than in 2000. [2] Cereals represented the main group of crops produced in 2022, followed by sugar crops (23%), vegetables (12%) and oil crops (12%).
Crop rotation has been employed for thousands of years and has been widely found to increase yield and prevent harmful changes to the soil environment that limit productivity in the long term. [3] Although the specific mechanisms regulating that effect are not fully understood, [ 4 ] they are thought to be related to differential effects on ...
This type of selection is a refined version of the mass selection procedure and differs as follows: Visually selected individuals out of the base population undergo progeny testing Individuals selected on basis of the progeny test data are crossed with each other in every possible way to produce seed to form the new base population.
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. [1] Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities.
In agriculture, postharvest handling is the stage of crop production immediately following harvest, including cooling, cleaning, sorting and packing. The instant a crop is removed from the ground, or separated from its parent plant, it begins to deteriorate.
Crop demand is expected to double as the world's population reaches 9.1 billion by 2050. Increasing the quantity and quality of food in response to growing demand will require increased agricultural production. Good agricultural practices, often combined with effective input use, are among the best ways to increase smallholder productivity ...
Theoretical production ecology is the quantitative study of the growth of crops. The plant is treated as a kind of biological factory, which processes light, carbon dioxide, water, and nutrients into harvestable products. The main parameters are temperature, sunlight, standing crop biomass, plant production distribution, and nutrient and water ...
