Influence of Different Colored Shade Nets on Micro Environmental Parameters and Pest Incidence of Various Ornamental Plants

Abstract

A field experiment was carried out at Floriculture and Landscaping Block, College of Horticulture, Anantharajupeta during 2022 and 2023. to study the Influence of different colored shade nets on microenvironmental parameters of various ornamental plants. The experiment consists of 25 treatments with three replications which were laid out in FRBD. The treatments were formed with two factors viz. Factor I (Colour shade nets, Green (C1), White (C2), Black (C3), Red nets (C4) and Open (C5) condition and Factor II plants (Pandanus veitchii (P1), Epipremnum aureum (P2), Sansevieria trifasciata (P3), Aglaonema commutatum var. Redgold (P4), Rhoeo spathacea (P5) were taken. The results shown that the maximum temperature was under black net (32.43, 34.10 0C in first and second year respectively), maximum RH was under black net (88.09, 83.11 % in first and second year respectively), lowest canopy temperature was under shade nets than open. Maximum light intensity (653.21, 669.4 lux in first and second year respectively), average PAR values were maximum under white net (718.05 µmol m-2 s-1) in both years. Mealy bug incidence was maximum under black net in both years during the period of study
