Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural output difficult. Therefore, agricultural productivity is usually measured as the market value of the final output ...
The term cropping system refers to the crops, crop sequences and management techniques used on a particular agricultural field over a period of years. It includes all spatial and temporal aspects of managing an agricultural system.
The main prewar agricultural products of the Confederate States were cotton, tobacco, and sugarcane, with hogs, cattle, grain and vegetable plots. Pre-war agricultural production estimated for the Southern states is as follows (Union states in parentheses for comparison): 1.7 million horses (3.4 million), 800,000 mules (100,000), 2.7 million dairy cows (5 million), 5 million sheep (14 million ...
Figure 2 [OLD]: Total Output vs. Total Input [top] & Output per unit Input vs. Total Input [bottom] Seen in TOP, the change in output by increasing output from L 1 to L 2 is equal to the change from L 2 to L 3. Seen in BOTTOM, until an output of L 1, the output per unit is increasing. After L 1, the output per unit decreases to zero at L 3.
Agricultural economics is an applied field of economics concerned with the application of economic theory in optimizing the production and distribution of food and fiber products. Agricultural economics began as a branch of economics that specifically dealt with land usage. It focused on maximizing the crop yield while maintaining a good soil ...
Good management of field residues can increase efficiency of irrigation and control of erosion. The residue can be ploughed directly into the ground, or burned first. In contrast, no-till, strip-till or reduced-till agriculture practices are carried out to maximize crop residue cover. Simple line-transect measurements can be used to estimate ...
Agriculture in Kenya dominates Kenya's economy. [1] 15–17 percent of Kenya's total land area has sufficient fertility and rainfall to be farmed, and 7–8 percent can be classified as first-class land. [2] [3] In 2006, almost 75 percent of working Kenyans made their living by farming, compared with 80 percent in 1980. [2]
For example, a project has the following inflows years Inflows respectively 1 100,000 2 150,000 3 200,000 If the project's payback is 2 years having an outflow of 250,000 the cut off period must be 2 years otherwise the project will be rejected.
