A 560m2 naturally ventilated greenhouse (Fig. 1) was constructed at the research farm of Department of Soil and Water Engineering, Punjab Agricultural University, Ludhiana. A similar greenhouse was also constructed at Krishi Vigyan Kendra, Faridkot. Capsicum was cropped during the studying period at both experimental areas in different period of time. Temperature inside the greenhouse at various places was recorded on hourly basis from 0700 hours to 1800. The total area of greenhouse was divided into a number of grid points at 0 m (ground level), 1 m, 2 m, 3 m, 4 m, 5 m and 6 m (cover) height. The study revealed that there was temperature gradient existed in air temperature at different grid points inside the naturally ventilated greenhouse. In morning hour east side of the greenhouse exhibited more temperature as compared with west side greenhouse. Similarly, during evening time the temperature of the east side of the greenhouse was lower than the west side. At 5m and 6m height, from where hot air mass leaving the greenhouse temperature were recorded more as compared with other part of the greenhouse. The present study is helpful for deciding management procedure for crop production inside the greenhouse.
