Abstract:
Present investigation is carried out to find out response of betelvine to different shading materials. The experiment was carried out in the Research Farm, Kalyani, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, during the year 2013 to 2015 under boroja condition. Popular bangla cultivar of betelvine Ghanagatte was used for the present study. In control treatment (T1) plants were grown in normal boroja condition while in full light treatment (T2) entire shading material was removed and plants were exposed to direct sunlight throughout different seasons. In 35% light treatments (T3), more paddy straws were added over normal boroja while in 70% light treatment (T4), little bit paddy straws were removed from normal boroja and plants were moderately exposed to sunlight. In Blue Shaded treatment (T5), boroja was covered with blue colored plastic shading material, in Green shaded treatment (T6) and Red shaded treatments (T7), Green and red colour plastic shade was used respectively. Observations were recorded on the traits like leaf length (cm), leaf width (cm), vine elongation (cm), 100 leaves dry weight (g), SPAD values, leaf area (cm²), and leaf yield vine^-1. Growth of the betelvines shaded with polythene (perforated) sheets (blue, red, and green) was better than those shaded with cereal straw of different density or those completely unshaded. Betelvines shaded with blue polythene sheet produced longer vines with more number of leaves which were better in all dimensions like length, width, area and dry weight. Yield and yield quality of betelvine can be improved by using perforated polythene as shading material instead of cereal straw and blue colored polythene was best shading material for betelvine.
