The processes that determine tomato crop growth and yield are considered in detail, with emphasis on the influence of environmental factors such as light, CO2, temperature, humidity and salinity. The main topics are as follows: Biomass production (leaf area and light interception, leaf and crop photosynthesis); Crop and fruit growth; Biomass ...

Abstract This chapter focuses on the various processes that determine the growth and yield of tomatoes, with emphasis on the influence of environmental factors and crop management, such as light, carbon dioxide, temperature, humidity, salinity, plant density and leaf and fruit pruning.

MODELLING FOR CROP GROWTH CONTROL
Acta Horticulturae, 1989In relation to the control of crop growth it is necessary to consider the aspect of time constants. Some growth characteristics, such as photosynthesis and transpiration have a rapid response to control actions, whereas other characteristics, such as development and morphogenesis show a much slower response.

This chapter addresses the problem of greenhouse crop growth control using a hierarchical control approach. The proposed control scheme consists of two layers. In the lower one, any of the controllers described in Chap. 3 are used. The upper layer calculates optimal climate setpoints based on different criteria.

Nitrogen and the growth of potato crops
1995The lengthening of the period of full soil cover in response to increasing nitrogen supply can be explained from the effects of nitrogen on the rate of leaf expansion and on stem branching. Nitrogen supply modifies most other developmental processes or plant attributes only marginally or transiently.

Growth of crops, plants or plant parts is defined as the irreversible increase in size whereas development is the continuous change in plant form and function with characteristic transition phases. Growth is primarily associated with capture and allocation of resources whereas development is mostly related to non-resource environmental cues such as ...

Effects of DDT on the growth of crop plants
Environmental Pollution, 1989The effects of DDT on the germination and growth of plants were studied using many crop species. Of the species tested, oil-rich seeds of plants, such as peanut (Arachis hypogaea) and mustard (Brassica juncea), were more prone to DDT induced inhibition of germination and subsequent plant growth than cereals, pulses and fibre crops, like rice (Oryza ...

SIMULATING GROWTH AND DEVELOPMENT OF TOMATO CROP
Acta Horticulturae, 2009Crop models are powerful tools to test hypotheses, synthesize and convey knowledge, describe and understand complex systems and compare different scenarios. Models may be used for prediction and planning of production, in decision support systems and control of the greenhouse climate, water supply and nutrient supply.

Gibberellic acid and the growth of crop plants
The Journal of Agricultural Science, 19561. Field trials with gibberellic acid on grass, wheat, potatoes, turnips, carrots, peas, runner beans, lettuce, celery, blackcurrants, kale and maize are described. The effects on plant growth and crop yield were determined.2. The experiments on grassland were carried out between July 1953 and June 1956, and included trials at four different centres ...
