Abstract: The experiment was carried out at High-Tech Farm, Department of Horticulture, College of Agriculture, Dr. B.S. Konkan Krishi Vidyapeeth, Dapoli for investigating the effects of different shade intensities on growth performance of Chilli seedlings. The experiment laid out by randomized block design having seven treatments viz., T₁-U shaped tunnel covered with 25% shade net, T₂-U shaped tunnel covered with 50% shade net, T₃-U shaped tunnel covered with 75% shade net, T₄-U shaped tunnel covered with LDP paper, T₅-U shaped tunnel covered with coconut leaves, T₆-U shaped tunnel covered with gunny bags and T₇-U shaped tunnel without coverings and which was replicated by three time. The minimum days required for germination was recorded in the treatment T₄ (7.33 days). Among all the treatments, T₆ significantly influenced growth and health of seedlings and produced the maximum seedling height (32.83 cm), numbers of functional leaves (16.53), leaf area (17.85 cm²), diameter at collar region (3.93 cm), plant spread (21.77 cm), length of tap root (6.87 cm), numbers of adventitious roots (59.47), fresh weight (6.817 g), dry weight (1.0005 g), absolute growth rate (1.955 cm^.day^-1), relative growth rate (0.045 cm^.cm^-1day^-1) and minimum number of weeks (3 weeks) required for transplanting. The considering overall performance of the different shade intensities, it is concluded that the Chilli seedlings performed better in terms of days required for germination and their growth was found best in ‘U’ shaped tunnel covered with gunny bags under Konkan agro-climatic condition of Maharashtra State.
