The success or failure in sustainability of crop production depends on local weather and climatic conditions, and year-toyear variations within a region. one means of alleviating climatically induced stress is through modifications of microclimate which include any artificially introduced changes in the composition, behavior or dynamics of the atmosphere near the ground so as to improve the environment in which crops grow. In other words, microclimate modification is an intended change in the soil-plant- atmosphere system, which alleviates stress or prevents damage with the aim of attaining improved yields. Modifications of micro-climate are intended to bring about changes in one or more of the meteorological parameters. (S.S.Hundal 2005) Partial control of the microclimatic conditions, which have a major influence on plant growth characteristics, can be achieved in glasshouses or poly-greenhouses. Greenhouses are the framed or inflated structures covered with transparent or translucent and shade net materials large enough to grow crops under partial or fully controlled environmental conditions to get optimum growth and productivity. These poly-greenhouse structures have provided a new scope for commercial application of high value crops. (Ganesan, M 1999) Nimje and Shyam (1993) obtained that the mean monthly temperatures at 8 AM and 2 PM during January to October were found to be higher by 20 inside the greenhouse than in the open field. Higher temperature during daytime was due to trapping of short wave radiation in the greenhouse under partially closed conditions. They also observed that the relative humidity was higher inside the greenhouse than in the open field condition. Kaname and Itagi (1973) found that the light intensity in the greenhouse was lower than in the open field. Cheemaet al, ( 2004) found that the early and higher yield of different vegetable crops inside the polyhouse was mainly because of better microclimate such as higher temperature (4-9°C than the nearby open field) observed during winter months
