Abstract:
Garden rue (Ruta graveolens L.) strong smelling rue, commonly known as ‘Nagadali’ belongs to family Rutaceae. A field experiment was conducted at College of Horticulture Bagalkote, University of Horticultural Sciences, Bagalkote during kharif 2019-20 with study entitled, “Performance of Garden rue (Ruta graveolens L.) to different levels of irrigation and mulches on growth and yield under Northern dry zone of Karnataka” was carried out to find out best irrigation levels and mulches in garden rue. In experimental plot, twelve treatment combinations with four levels of irrigation (I1:100%, I2:80%, I3:60% and I4:40% Cumulative pan evaporation) and three different types of mulches (M1: Without mulch, M2: sugarcane trash and M3: polythene mulch) were evaluated in split plot design with three replications for growth and yield parameters under field condition. Among treatments, combination of I2M3: Irrigation 80% CPE + polythene mulch is best as it gave maximum growth parameters such as plant height (43.13 cm), number of branches per plant (22.80), plant spread (40.17 cm), soil moisture (17.50%) and yield attributes like fresh herbage yield (469.7 g/plant and 18.47 t/ha), dry herbage yield (116.8 g/plant and 4.89 t/ha) at final harvest. Significantly in case of weed density (10.67 m2), water use efficiency (13.33 kg/ha/cm3), minimum days to first flowering (92.67 days) and 50% flowering (107.00 days) at final harvest were recorded in combination of I4M3: Irrigation 40% CPE + polythene mulch. Hence I2M3:Irrigation 80% CPE + polythene mulch recorded maximum crop growth and productivity of garden rue under Northern dry zone of Karnataka.
