Evaporative Cooling Efficiency Of A Fogging System For Greenhouses, Hasan Hüseyi̇n Öztürk Jan 2003

Evaporative Cooling Efficiency Of A Fogging System For Greenhouses, Hasan Hüseyi̇n Öztürk

Turkish Journal of Agriculture and Forestry

The objective of this study was to investigate the efficiency of fogging system (FS) for greenhouses. The experiments were carried out in a multi-span plastic greenhouse (PG), 105.6 m wide and 205 m long, made of 11 spans. The FS consists of a water softener and filters to prevent nozzle clogging, a water reservoir, pumps and a pressure regulator, and fog generating nozzles (FGN). The required pressure for FGN was 4.5 atm. Three nozzle lines with 82 FGN were installed in each span of the PG. At each nozzle line, 82 FGN were uniformly located at 2.5 m nozzle spacing. …


Assessment Of Day-Neutrality Scoring Methods In Strawberry Families Grown In Greenhouse And Field Environments, Sedat Serçe, James F. Hancock Jan 2003

Assessment Of Day-Neutrality Scoring Methods In Strawberry Families Grown In Greenhouse And Field Environments, Sedat Serçe, James F. Hancock

Turkish Journal of Agriculture and Forestry

A strawberry plant is considered day-neutral if it can form flower buds under both long and short day conditions; however, researchers use different methods to score day-neutrality. We studied the relationship among several different evaluation methods for day-neutrality and analyzed the possibility that greenhouse screens can be used to predict field flowering performance. The evaluation methods included: 1) flowering within 100 days from germination in a greenhouse; 2) flowering during the first summer after planting in the field; 3) flowering under both short and long days in the second year in a greenhouse; and 4) flowering under both short and …
