Production Systems in Agriculture

2021
The essay focuses on the institutional and technical elements that made Lombard agriculture a modern sector, capable not only to ensure subsistence to three millions people, but also to supply raw materials to local and foreign industries, and in general to give a remarkable contribute to the regional economy, both private and public.

Agricultural Productivity Revisited

American Journal of Agricultural Economics, 1997
AbstractThis paper describes production accounts for agriculture. Output is defined as gross production leaving the farm as opposed to real value added. Inputs are not limited to capital and labor but include intermediate inputs as well. We derive index numbers of gross output, capital, labor, and intermediate inputs.

Artificial neural networks and adaptive neuro-fuzzy inference system in energy modeling of agricultural products

Predictive Modelling for Energy Management and Power Systems Engineering, 2021
The expected yield of agricultural production is a significant factor in energy management, because it can help us in an operation like detecting and diagnosing faults, conducting system commissioning, as well as evaluating agricultural energy efficiency

MODELLING AGRICULTURAL PRODUCTION

Acta Horticulturae, 1986
In modelling in general and biological modelling in particular two approaches may be distinguished: a descriptive and an explanatory approach. In descriptive models the system and its behaviour are described at the same level at which the observations about it are made.

Effects on Agricultural Productivity

1988
The dry tropics are characterized by a short and intense rainy season followed by a relatively long dry season. Generally the rainy season lasts from two to four months; the amount of rainfall received ranges between 400 and 1200 mm; the rainy season may have one peak (unimodal) or two peak periods of rainfall (bimodal).
