Basically capsicum is a cool season tropical crop and lacks adaptability to varied environmental conditions. Despite its economic importance, growers are not in a position to produce good quality capsicum with high productivity due to various factor affecting i.e. temperature, relative humidity, pest, diseases, rainfall, light intensity and crop factors (flower and fruit drop). Due to erratic behaviour of weather, the crops grown in open field are often exposed to fluctuating levels of temperature, humidity, wind flow etc. which ultimately affect the crop production adversely. Hence, to obtain a good quality produce and production during off season, there is a need to cultivate capsicum under protected condition such as green houses or polyhouses, shade net house. Protected cultivation has tremendous scope to improve the economy of the growers as well as fulfill the demand for vegetable crops throughout the year from the small piece of the land. Effect of different color shade net and shading percent on plant growth performance as well as on micro climate was studied and its finding is presented in this book.
