Analysis of humidity effects on growth and production of glasshouse fruit vegetables. By J.C. Bakker. Topics: GREENHOUSES, HUMIDITY, FRUIT VEGETABLES, PLANT RESPONSE Author: J.C. Bakker. Four discrete humidity treatments (, , and kPa vapour pressure deficit) were maintained continuously for 28 days from mid-Jan. and their effect on the growth and yield of a long-season tomato crop ( by: The system removes 40 g of condensate per hour per square metre of greenhouse floor from the humid air sufficient during periods when heating is applied and ventilation is minimized. The heat transferred at the cold surface by condensation is less than one-third of the total heat removed by the system at a relative humidity of 80%.Cited by: 8.

  Abstract. The climatic conditions are one of the most striking differences between the growing conditions of field crops and those of protected crops, especially in the moderate climate zones. The increased temperature and the humidity in greenhouses are the dominating factors responsible for the by: 1. A model was developed using Artificial Neural Networks (ANNs) based on Principal Component Analysis (PCA), to accurately predict the air humidity. inside an experimental greenhouse located in Daegu (latitude °N, longitude °E, and altitude 48 m), South Korea.

Bakker () reported that under high relative humidity, an increase in vpd determined only slight variations in qualitative fruit characteristics of different vegetables and he observed a reduction in mean fruit weight of cucumber and eggplant, and an increase in tomato weight. In the present study the increase of vpd from to kPa caused a relevant reduction in fruit fresh weight (∼−10%).Cited by: The proportion of total plant weight in fruit was only reduced slightly at 17 mS. The effects of salinity on fruit growth were investigated for seven weeks beginning seven days after anthesis. increase is % or less. This specifies the importance of glasshouse cultivation of vegetables and ornamentals as an augment against the present situation of food crisis in Nigeria. Glasshouse vegetable production has potential as a niche market for out-of-season, all year round produce and as a sustainable method of production.   Temperature affects growth & development of vegetable crops during different phases of growth such as seed germination, general survival, development of economic parts, flowering, pollination and fruit set, quality of produced, seed production, seed storage, seed .
